Girma A, Genet A. Prevalence and factors associated with intestinal parasitic infections among preschool-aged children in Ethiopia: A systematic review and meta-analysis. Parasite Epidemiol Control 2024; 26:e00368. [PMID: 39076827 PMCID: PMC11284566 DOI: 10.1016/j.parepi.2024.e00368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 05/28/2024] [Accepted: 07/05/2024] [Indexed: 07/31/2024] Open
Abstract
Intestinal parasitic infections (IPIs) pose a serious public health threat across the globe, particularly in children residing in poor and most deprived communities like Ethiopia. Many published articles were available separately, and a detailed nationwide review was essential to combine all the results to draw a conclusion and avoid any informational conflicts, ambiguities, or misunderstandings. Therefore, this systematic review and meta-analysis aimed to provide pooled estimates for the individually available data on IPIs and its determinant factors among preschool-aged children (PSAC) in Ethiopia. Published and unpublished articles from various electronic databases were accessed using MeSH terms and keywords. I 2 and sensitivity analysis tests were used to assess potential sources of heterogeneity across studies. Funnel plot, Begg's, and Egger's regression tests were used to check publication bias. A random-effects model with a 95% confidence interval (CI) was used to calculate the pooled estimate of IPI. In this meta-analysis, a total of 14,994 PSAC were included in the 32 eligible studies. The pooled national prevalence of IPIs among PSAC was 32.52% (95% CI: 26.24, 38.80). Of these, single and mixed infections contribute 31.08% and 1.44%, respectively. According to the subgroup analysis, the highest prevalence was observed in simple random studies (39.61%; 95% CI: 29.19, 50.03), the Tigray region (58.00%; 95% CI: 54.10, 61.90), studies conducted in >384 (39.47%; 95% CI: 27.73, 51.20) sample sizes, cross-sectional studies (32.76%), community-based studies (42.33%; 95% CI: 31.93, 52.74), and from 2005 to 2016 (34.53%; 95% CI: 20.13, 48.92) study periods. Intestinal parasites were significantly associated with eating raw fruits and vegetables (aOR = 3.21; 95%CI: 1.11-5.31). The high prevalence of STHs observed in this systematic review and meta-analysis underscores the need for appropriate control and prevention strategies suitable for PSAC in Ethiopia.

Abstract
Purpose Parasitic infections are a primary cause of illness worldwide and a public health problem. This study highlighted the prevalence of intestinal parasitic (IP) infections and their updated epidemiologic status from 2019 to 2023 at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Patients and Methods A retrospective study was conducted from 2019 to 2023 at King Abdulaziz University Hospital. The laboratory results, socio-demographic information, and the year of data collection were collected from the hospital's parasitology laboratory. The data were analyzed using SPSS version 26. Ethical approval was obtained from the National Committee of Bioethics (NCBE) - King Abdul Aziz City for Science and Technology, with an approval number of 258-22. Results During the study period, 7673 stool samples were requested for intestinal parasite examination. The prevalence of IP infection from 2019 to 2023 was 212/7673, with a percentage of 2.8%. Infected patients had a mean (SD) age of 37.68 (17.27) years. Most infected patients were females (61%) and from Saudi Arabia (37.1%). Most stool samples were brown (79.1%), and about half were soft (51.7%). 2019 had the highest number of infected cases (28.3%), while the number of cases decreased in 2023 (8.8%), the lowest during five years. The most predominant parasite among study subjects was Blastocystis hominis (48.11%). Conclusion The prevalence of IP infection is lower than in previous comparable surveys. Maintaining personal hygiene, conducting epidemiological surveillance, and enhancing environmental sanitation can prevent and control infections.

Abstract
INTRODUCTION People with visual impairments and blindness face challenges in performing regular tasks such as maintaining proper sanitation, which makes them vulnerable to intestinal parasitic infections. AIMS AND OBJECTIVES This study aims to examine the prevalence and distribution of intestinal parasitic infections in children and adolescents with ocular diseases and to assess if the lockdown during the COVID-19 pandemic affected these rates. METHODS This retrospective, hospital record-based study was conducted among children and adolescents attending the Regional Institute of Ophthalmology in Kolkata, India. It involved routine stool examinations as part of their treatment during 2019-2020. Early morning stool specimens were collected and brought to the institute laboratory in containers. Stools were examined under a microscope for cysts, ova, parasites, and adult worms. Findings were recorded in the laboratory record book. These data were then extracted into a spreadsheet and analyzed using IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York). RESULTS The prevalence of intestinal parasitic infections was 8.59% (59 out of 687 patients). Among those 59 positive cases, Ascaris lumbricoides, Giardia lamblia, Entamoeba histolytica, Trichuris trichiura, Taenia spp., Enterobius vermicularis, and Isospora belli were detected in 27 (45.8%), 15 (25.4%), 8 (13.6%), 6 (10.2%), 3 (5.1%), 2 (3.4%), and 1 (1.7%) patients, respectively. The positivity rate of stool samples was higher from September and thereafter from January to March. The sample positivity rate was higher post-pandemic and lockdown, but not statistically significant (11.5% vs. 5.3%; χ²=4.044, df=1, p=0.44). CONCLUSION Ascaris lumbricoides was the most commonly observed intestinal parasite in children and adolescents with ocular disease in our setting. Seasonal variation was noted with higher case positivity at the end of the rainy season and thereafter in winter. Therefore, we propose to strengthen the routine deworming program during this period in Eastern India. Higher sample positivity after the pandemic may be attributed to school closures during the lockdown period, which might have caused some children to miss their routine deworming medication.

Abstract
Purpose In this study, it was aimed to determine the 5-year prevalence of intestinal parasites in patients admitted to the Microbiology laboratory of a tertiary hospital in Somalia. Intestinal parasites; Types of patients, age and sex of the patients, and the distribution by years were examined. Patients and Methods Stool samples were examined using wet preparation, native lugol and trichrome staining methods. Statistical analysis was performed using IBM SPSS V23 software and a P value of <0.05 was considered statistically significant. Tables and figures were used to show the results. Results One or more parasites were detected in 6766 of 56,824 stool samples examined. It was observed that Giardia lamblia had a higher prevalence than other parasites (60.84%) in a five-year period. Entamoeba histolytica (33.07%) second rank and Ascaris lumbricoides (3.18%) third rank according to their prevalence. When the distribution of the parasite population by gender is evaluated; no statistically significant difference was found (p = 0.235). When the frequency of parasites was evaluated according to age groups, it was seen that the prevalence of parasites between the ages of 0-15 was higher (45.5%) compared to other age groups. A statistically significant difference was found between the distribution of parasite groups according to age groups (p < 0.001). Conclusion Considering the effects of intestinal parasites on public health, it is still considered to be an important health problem for developing countries. It is thought that the frequency of parasitic diseases in society will decrease with the education of individuals, effective diagnosis, treatment, and implementation of preventive measures.

Abstract
BACKGROUND Soil-transmitted helminth (STH) infections are global health problem, especially in low-income countries. Main objectives of this study were to estimate the prevalence and intensity of STH and its risk factors among school children in Kandahar city of Afghanistan. METHODOLOGY/PRINCIPAL FINDINGS This was a school-based cross-sectional analytical study, with data collected during eight-month-period (May-December, 2022) from 6- and 12-years old school children in Kandahar city, Afghanistan. All the stool samples were examined by saline wet mount method and Kato-Katz technique. Data were analyzed by using descriptive statistics, Chi square test, and multivariate logistic regression. A total of 1275 children from eight schools of Kandahar city were included in this study. Mean age of these children was 8.3 years with 53.3% boys. The overall prevalence of any intestinal parasitic infection was 68.4%. The overall prevalence of STH infection was 39.1%, with Ascaris lumbricoides (29.4%) as the most prevalent STH species. Mean intensity of overall STH infection was 97.8. Multivariate logistic regression revealed playing barefoot (AOR 1.6, 95% CI 1.1-2.2), not washing hands after defecating and before eating (AOR 1.3, 95% CI 1.0-1.7), having untrimmed nails (AOR 1.4, 95% CI 1.1-1.8), and belonging to poor families (AOR 1.3, 95% CI 1.0-1.7) as the risk factors associated with the predisposition of school children for getting STH in Kandahar city of Afghanistan. CONCLUSIONS/SIGNIFICANCE There is high prevalence of STH among school children of Kandahar city in Afghanistan. Most of the risk factors are related to poverty, decreased sanitation, and improper hygiene. Improvement of socioeconomic status, sanitation, and health education to promote public awareness about health and hygiene together with periodic mass deworming programs are better strategies for the control of STH infections in Afghanistan.

Santos MCS, Oliveira GLD, Mingoti SA, Heller L. Effect of environmental factors in reducing the prevalence of schistosomiasis in schoolchildren: An analysis of three extensive national prevalence surveys in Brazil (1950-2018). PLoS Negl Trop Dis 2023; 17:e0010804. [PMID: 37459358 PMCID: PMC10374055 DOI: 10.1371/journal.pntd.0010804] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 07/27/2023] [Accepted: 06/03/2023] [Indexed: 07/29/2023] Open
Abstract
BACKGROUND Over seven decades, Brazil has made admirable progress in controlling schistosomiasis, and a frequent question about the explanation for this reduction refers to the effect of improving environmental factors in the country. This article seeks to identify factors related to the change in the epidemiological situation of schistosomiasis mansoni infection by analyzing three national prevalence surveys conducted since 1950. METHODOLOGY/PRINCIPAL FINDINGS This is an ecological study analyzing an unbalanced panel of data based on national surveys and considering the municipality as the unit of analysis. The sample consisted of 1,721 Brazilian municipalities, in which a total of 1,182,339 schoolchildren aged 7-14 were examined during the three periods corresponding to each survey (1947-1953, 1975-1979, and 2010-2015). The percentage of municipalities with zero cases of schistosomiasis was: 45.4%, 54.2% and 73.7%, respectively for those periods. A zero-inflated Poisson regression model, with fixed and random effects, was fitted to assess the association between candidate factors and disease prevalence using a significance level of 5%. There was a significant decrease in disease prevalence between the first and last periods analyzed (RR 0.214, CI 0.184-0.249), with a protective association with access to sanitation (RR 0.996, CI 0.994-0.998), urbanization (RR 0.991, CI 0.989-0.993), and living in own households (RR 0.986, CI 0.983-0.989); and an inverse association with piped water supply (RR 1.010, CI 1.008-1.011). CONCLUSION The findings of this study indicate a decrease in the prevalence of schistosomiasis over seven decades in schoolchildren from the analyzed Brazilian municipalities, associated with environmental factors and social conditions. The increased access to piped water in the municipalities apparently triggers other ways of contact with unsafe water bodies, generating new transmission routes and suggesting the need for a systemic approach concerning contact with water.

Eur J Pediatr 2023:10.1007/s00431-023-04961-x. [PMID: 37041294 DOI: 10.1007/s00431-023-04961-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 03/22/2023] [Accepted: 03/30/2023] [Indexed: 04/13/2023]
Abstract
Eosinophilia is common in children and may be caused by various disorders. Large-cohort studies, including mild cases, are limited in children. This study aimed to reveal underlying etiologies of childhood eosinophilia and to create a diagnostic algorithm. Children (< 18 years) with absolute eosinophil counts (AECs) ≥ 0.5 × 109/L were reviewed from medical files. Clinical characteristics and laboratory values were recorded. Patients were grouped based on the severity of eosinophilia as mild (0.5-1.5 × 109/L), moderate (≥ 1.5 × 109/L) and severe (≥ 5.0 × 109/L). An algorithm was formed to evaluate these patients. We included 1178 children with mild (80.8%), moderate (17.8%) and severe eosinophilia (1.4%). The most common reasons of eosinophilia were allergic diseases (80%), primary immunodeficiency (PID) (8.5%), infectious diseases (5.8%), malignancies (0.8%) and rheumatic diseases (0.7%). Only 0.3% of children presented with idiopatic hypereosinophilic syndrome. Allergic diseases and PIDs were the most common etiologies in mild/moderate and severe groups, respectively. The median duration of eosinophilia was 7.0 (3.0-17.0) months in the study population and was the shortest in severe cases (2.0 (2.0-5.0) months). Multiple logistic regression analysis demonstrated food allergy [OR:1.866, 95%CI:1.225-2.842, p = 0.004] and PIDs [OR:2.200, 95%CI:1.213-3.992, p = 0.009] as independent factors for childhood eosinophilia. A diagnostic algorithm including mild form was presented for childhood eosinophilia. Conclusion: Eosinophilia was frequently determined due to secondary causes; allergic diseases in mild/moderate eosinophilia, PIDs in severe group. Etiology of eosinophilia was diverse, and an algorithm concerning the severity of eosinophilia would be practical and rational. What is Known: • In children, eosinophilia is common, and mild eosinophilia occurs frequently. • Malignancies presents frequently with severe eosinophilia. What is New: • Primary immunodeficiencies were not a rare cause of eosinophilia, especially in countries such as the Middle East and eastern Mediterranean countries, where the countries consanguineous marriages are common, and should be investigated in children with eosinophilia who do not have allergic or infectious diseases. • In literature, there are many algorithms about childhood hypereosinophilia. However, mild eosinophilia is extremely important in children. Because all patients with malignancy and most of the patients with rheumatic diseases presented with mild eosinophilia. Therefore, we proposed an algorithm for childhood eosinophilia that includes mild eosinophilia besides moderate and severe cases.

Abstract
Background Despite global interventions to prevent and control diarrhea, it remains a public health problem leading to childhood morbidity and mortality majorly in developing countries. According to the World Health Organization, data from 2021 indicated that diarrheal disease is responsible for 8% of deaths in children under the age of 5. In the world, more than 1 billion under-five children live in poverty, social exclusion, and discrimination affected by intestinal parasitic infections and diarrhea disease. In sub-Saharan African countries like Ethiopia, diarrheal diseases and parasite infections continue to cause significant and persistent morbidity and mortality in under-five children. Therefore, the purpose of this study was to assess the prevalence and associated factors of intestinal parasites and diarrheal diseases in children under the age of 5 years in Dabat District, Northwest Ethiopia in 2022. Method A community-based, cross-sectional study was carried out from September 16 to August 18th 2022. Four hundred households with at least one child under the age of 5 years were recruited by simple random sampling technique. Sociodemographic, clinical, and behavioral factors were also collected using pretested interviewer-administered questionnaires. Data was entered into Epi-data version 3.1 and exported to Statistical Package for Social Science (SPSS) version 25 for analysis. Binary logistic regression was performed to identify factors associated with diarrhea and intestinal parasitic infections. The level of significance was computed at a P-value ⩽ .05. Descriptive statistics such as frequency and other summary statistics were used for describing sociodemographic variables and determining the prevalence of diarrhea and intestinal parasites. Tables, figures, and texts were used to present the findings. The variables having a P-value of less than .2 in the bivariable analysis were entered into the multivariable analysis at a P-value of ⩽.5. Results According to this study, the prevalence of diarrhea and intestinal parasites among under-five children was 20.8% (95% CI: [16.8-37.8] and 32.5% (95% CI: [28.6, 37.8], respectively. In multivariable logistic analysis at a P-value of ⩽.5, the educational level of mothers (Adjusted odds ratio [AOR]: 3.7, 95% CI: [1.52, 8.95], residence (AOR: 4.7, 95% CI: [1.52, 8.09]), undernutrition (AOR: 3.6, 95% CI: [1.09, 11.3]), latrine availability (AOR:3.9, 95% CI: [1.23, 9.56]), types of the latrine (AOR: 5.9, 95% CI: [3.42, 11.66]), water treatment (AOR = 7.6; 95% CI: [6.4, 12.7]), eating uncooked vegetable or fruits (AOR = 4.6; 95% CI: [1.025, 15.2]), and source of water (AOR = 4.5; 95% CI: [2.32,8.92]) were significantly associated with diarrheal disease. Intestinal parasitic infection was also significantly associated with undernutrition (AOR = 3.9; 95% CI: [1.09, 9.67]), latrine availability (AOR = 2.1; 95% CI:[1.32, 9.32]), types of the latrine (AOR = 2.8; 95% CI: [1.92, 8.12]) residence (AOR = 4.7; 95% CI: [1.52, 8.09]), water treatment, source of water for drinking (AOR = 4.5; 95% CI: [2.32, 8.92]), eating uncooked vegetables or fruits (AOR = 6.7:95% CI: [3.9, 9.8]), and deworming children with anti-parasitic medication (AOR = 2.4; 95% CI: [1.34, 5.62]), washing hands after latrine used (AOR = 2.2: 95% CI: [1.06, 3.86]). Conclusion The prevalence of diarrhea and intestinal parasite among under-five children was 20.8% and 32.5%, respectively. Undernutrition, latrine availability, types of latrines, residence, eating uncooked vegetables or fruits, and source of water for drinking and water treatment were associated with intestinal parasitic infection and diarrheal disease. Deworming children with antiparasitic medications and washing hands after latrine use was also significantly associated with parasitic infection. Hence, awareness creation activities on latrine utilization and building, keeping personal hygiene, safe water supply, feeding cooked vegetables or fruits, taking anti-parasitic medications, practice hand washing habit after toilet use are strongly recommended.

BRAZ J BIOL 2023; 84:e266898. [PMID: 37075409 DOI: 10.1590/1519-6984.266898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Accepted: 11/29/2022] [Indexed: 04/21/2023] Open
Abstract
Intestinal parasitic infections (IPIs) are endemic worldwide and more prevalent in countries with unhygienic conditions. The objective of the research was to identify the prevalence of intestinal parasitic infections in rural and urban areas of Quetta, Balochistan and to check their associated risk factors including; age, gender, educational status, sanitary system and any other immunodeficiency. For this instance 204 stool samples were collected from the urban and rural population of Quetta, Balochistan. The participants with positive results for Intestinal Parasitic Infections were interviewed using close-ended questionnaire. From the findings of this study, it has been revealed that prevalence of Intestinal parasitic infections in rural and urban areas was 21%. Males were found more prevalent (66%) as compared to females (34%) due to higher risk of contacting to outer environment. The prevalence was higher in rural areas (23%). The most prevalent intestinal parasite was Entamoeba histolytica (48%). Other prevailing parasites were Hymenolepis nana (26%), Giardia Intestinalis (17%), Trichomonas hominis (5%) and Trichuris trichiura (5%). The majority of patients were having lower socio-economic (52%) and educational status (48%). Educational status of 48% patients was primary or below primary. Most of the participants with positive results did not have hand washing habit (62%) and didn't have the closed sanitary system (71%). The intestinal parasitic infections were more prevalent among children aged from 1-10 (33%). This may be a result of poor hygiene in children. The study will contribute to lower down the prevalence in the studied areas by the application of different preventive measures in future.

Epidemiologic Investigation of Intestinal Parasite Infection and Associated Risk Factors among Primary Schoolchildren in the Manzini and Lubombo Provinces, the Kingdom of Eswatini. J Trop Med 2022; 2022:9190333. [DOI: 10.1155/2022/9190333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2022] [Revised: 10/09/2022] [Accepted: 11/01/2022] [Indexed: 11/16/2022] Open
Abstract
Although the deworming program has been executed since 2000, the intestinal parasitic infection (IPI) rates among primary schoolchildren (PSC) in the two provinces of the Kingdom of Eswatini investigated in 2010 remained high, reaching 32.2%. In this study, we monitored the IPI status along with the associated risk factors for PSC in two provinces—Manzini and Lubombo. After consent from their parents/guardians, a total of 316 samples collected from PSC with grades 1 to 3 from four primary schools in Manzini and Lubombo were examined by the Merthiolate-Iodine-Formaldehyde (MIF) method. In addition, demographic characteristics and risk factors acquired by questionnaire surveys were included to be statistically analyzed. The overall prevalence was 40.5% (128/316), of which the infection rate in Manzini and Lubombo was 28.8% (19/66) and 58.3% (74/140), respectively. Pathogenic protozoa had the highest infection rate of 20.6% (65/316), including Entamoeba histolytica/dispar (8.5%, 27/316), Giardia duodenalis (14.6%, 46/316), and Blastocystis hominis (9.8%, 31/316). In terms of helminth infection, the infection rate was quite low, 1.6% only, and these five infected cases included four cases of Hymenolepis nana and one case of Enterobius vermicularis infection. Present study showed that 27.8% (88/316) of PSC were infected by more than one pathogenic parasite. Personal hygiene like washing hands before a meal has a significant protection effect (OR = 0.32, 95% CI = 0.14–0.75,
). Rain or well water and the type of water supply from which they drank also showed a considerable risk factor (OR = 2.44, 95% CI = 1.25–4.79,
). The IPI rate in PSC seems unlikely changed compared to that of the previous survey conducted in 2010, especially when the pathogenic protozoan infection rate remains high. Treatment of infected PSC with appropriate medication to reduce intestinal pathogenic protozoan infection should be seriously considered by Eswatini Health Authority.

Abstract
Abstract
Background Intestinal parasites are a major public health problem in tropical countries. Over 1.5 billion people are infected with soil-transmitted helminths (STH), of which 225 million are in India. Parasitic infections are associated with poor sanitation, lack of safe potable water, and improper hygiene.
Materials and Methods The study was undertaken to ascertain the impact of control strategies, namely open-defecation free drive and mass drug administration of single dose albendazole. Stool samples received at AIIMS Bhopal Microbiology laboratory, across all age groups, were studied for protozoan trophozoites/cysts and helminthic ova.
Results Out of 4,620 stool samples, 389 (8.41%) were positive either for protozoal or helminthic infections. Protozoan infections were more common than helminthic infections with Giardia duodenalis infection being the most common, 201 (51.67%), followed by Entamoeba histolytica, 174 (44.73%). The helminthic infections constituted 14 (3.5%) of the positive stool samples with Hookworm ova in 6 (1.5%) cases.
Conclusion This study proves that strategies, namely “Swachh Bharat Abhiyan” and “National Deworming Day” started in 2014 and 2015 led to significant reduction of intestinal parasite infections in Central India, with a higher reduction of STH compared with protozoan parasite infection being ascribed to the activity spectrum of albendazole.

Abstract
The current study specifies the rate of spreading the parasites in fresh vegetables sold in shops located on the left and right sides of the city of Mosul. 600 samples were collected, 300 for each side left and right, with 15 samples of each Lettuce, Celery, Pepper, Tomatoes, Onions and Carrots. Results showed significant differences in the rates of contaminating variables with intestinal parasites at probability level (p<0.05) on both sides, where it was noticed that the percentage of contamination on the right side (39%) was higher than the one on the left side(26%). The results also showed that fresh vegetables are contaminated with three types of intestinal parasites: Entamoeba histolytica, Giardia Lamblia, Entamoeba coli, and four types of intestinal worms as follows: Ascaris lumbricoides, Trichuris trichura, Hymenolypis nana, Enterobius Vermiculoris. The highest contamination percentage with intestinal protozoa was found with Entamoeba histolytica parasite (67%) on the left side. On the right side, the percentage of contamination was Entamoeba histolytica (50%) in each of the tomato plants and coriander., and the highest percentage of contamination with intestinal worms was by Ascaris lumbricoides worm on the left side (40%) and in the right side (29%). Also shown from the results, the percentage of single contamination in the fresh vegetables was higher than the double and triple contamination. The single contamination was found with a percentage of (82-95%) on both sides, respectively and also noticed in the current study, the leafy vegetables (lettuce and celery) and Tomato, which are the most vegetables contaminated with parasites in both sides in comparison with the rest types of vegetables.
Keywords Contamination; intestinal parasites, vegetables; left and right sides

Abstract
Intestinal parasite infections are still prevalent in developing countries and in Cameroon where over 90% of the population is at high risk. To assess the distribution of intestinal parasitic infections and risk factors of the city of Yaoundé, both household and parasitological surveys were conducted from October to December 2019 among inhabitants of lowlands aged from 15 years and over. Stools samples were collected and screened for intestinal parasites presence using Kato Katz and Formol-Ether methods. Sociodemographic status, prevention measures against intestinal parasitic diseases and practices with increase exposition to risky environments were then recorded.
A total of 229 participants (142 females: 62.0%; 87 males: 38.0%) were enrolled for the study, and 24.02% (55/229) were found infected by helminthes (ten species) and/or protozoans (one species). Participant infection rates and risk varied by parasite species and socio-demographic factors. Global risk analysis showed that age (OR ranges: 3.78-15.96), anti-parasitic drug consumption (OR: 2.53), eating behavior,,hygiene (OR: 22.4), occupation (OR ranges: 1.92-3.53) and type of toilets (OR: 3.4) were strongly associated with risk of infection by intestinal parasites. The risk increased in 15-30 years age group for A. lumbricoïdes, T. trichiura and Schistosoma mansoni, unpredictably in those washing their hands before meals for A. lumbricoïdes and H. nana, in respondents using antiparasitic drugs as auto-medication for H. nana and in those using traditional toilets for A. lumbricoïdes. However, other variables with high OR values (> 5.0) might be potential risk factor for the occurrence of specific parasite infections. The study suggests the need for household sensitization and community actions including integrated environmental management as complement strategy to reduce intestinal parasite transmission in the city of Yaoundé.

Abstract
Intestinal parasite infection (IPI) is still a very important public health issue. The severity of the parasitic disease has been reported as a high infection in immunocompromised patients and children. Hence, this study aimed to investigate the prevalence of intestinal parasites among immunocompromised patients and children with various gastrointestinal system complications in Sana'a city, Yemen, with different variables, including genus and age, and explore the risk factors associated with parasitic intestinal infections. The study socioeconomic data and certain behavioral and environmental risk factors and stool samples were collected from immunocompromised adult and children's patients, including children (one to eight years old), pregnant women, diabetes mellitus patients, cancer patients, HIV patients, and older adults. Out of 436 fecal samples, the overall prevalence rate of IPIs among immunocompromised patients and children in Sana'a was 51.8%. In contrast, the rate of infection in children (26.1%) was higher than that in old patients (25.7%) and in females (38.5%) and higher than that in males (13.3%). The protozoa (44.5%) have been shown more than intestinal helminths (7.3%) in samples, and the most common intestinal protozoan was Giardia lamblia and Entamoeba histolytica (13.8% and 12.8%), respectively. The most common intestinal helminthiasis was Hymenolepis nana with 1.8%. Concluding that the rate of infection was high for several reasons, including lack of commitment to hygiene as not handwashing after using the toilet (88.9%), eating uncovered food (56.3%), poor sanitation as lack of water sources (59.5%), reduced health education, and presence of other family members infected by parasites (61.3%). Interventions are required to reduce intestinal parasites, including health education on personal hygiene for patients, increasing awareness, and improving the environment and healthcare system.

Abstract
The three main intestinal helminth infections (IHIs), ascariasis, trichuriasis, and hookworm, are common clinical disorders worldwide. These IHIs are more prevalent in tropics and subtropical countries especially in developing countries like sub-Saharan Africa responsible for morbidity, mortality, and physical as well as intellectual growth retardation in children. In Ethiopia, the burden of IHIs appears in all ages mainly due to factors like lack of education, low socio-economic status, and inadequate supply of drugs and proper awareness. The present study was carried out to access the prevalence of intestinal helminth infections and associated risk factors among school children in Adola town from Guji Zone, Oromia, Ethiopia, from August 2019 to December 2019. 404 stool samples were collected in a clean, dry, screw-capped, and wide-mouthed plastic container, fixed with 10% formal-saline solution, and transported to the Adola Hospital laboratory for further microscopic analysis by wet mount following formal ether concentration technique. Data were analyzed using SPSS version 20 by binary logistic regression model using odd ratio with 95% CI. The overall prevalence of IHIs among school children was found to be 33.91% (137/404). Rate of double infection was noted to be 2.72% (11/404). Most dominant species was Ascaris lumbricoides (8.9%) followed by Hymenolepis nana (7.7%), Taenia saginata (5.4%), hookworm (4.7%), Trichuris trichiura (2.5%), Schistosoma mansoni (2.2%), Enterobius vermicularis (1.7%), and Strongyloides stercoralis (0.7%), respectively. Highest prevalence was observed in male students (39.6%) compared to female students (28.8%) (P < 0.05). The prevalence of IHIs among school children in the age group of 6-10, 11-15, 16-20, and above 20 was 49.6%, 35.8%, 10.9%, and 3.6%, respectively (P < 0.05). IHI was significantly associated with some of the risk factors such as gender, educational level of students', toilet usage habit, habit of hand washing, hand washing habit before feeding and after defecation, purpose of hand washing, and awareness to intestinal helminths (P < 0.05). In the study area, the prevalence of IHIs is moderately high and represents a public health problem in the school children. Therefore, all stakeholders should pay attention to raise awareness about health education programs such as proper personal hygiene, environmental sanitation, improving the quality of drinking water, and treatment to reduce the consequences of intestinal helminths.

Abstract
BACKGROUND Infections with intestinal parasites are a major public health problem in children in developing countries like Kenya. School going children are considered at most risk and are included in school-based de-worming program. Less focus is given to pre-school children and information is scarce about intestinal parasitosis among this age group. In this study, we determined the prevalence and intensity of protozoa and helminth infections, and associated risk factors in an informal settlement. METHODS A community based cross-sectional study was conducted from October 2016 to January 2017 among 406 children aged 2-5 years in Kibera informal settlements in Nairobi County, Kenya. Structured interviewer-administered questionnaire was used to collect sociodemographic information and data on associated factors. Stool samples were examined microscopically using formal ether concentration, iodine wet mounting, modified Ziehl-Neelsen staining, and Kato-Katz methods. Multivariable logistic regression analysis was used to identify risk factors associated with intestinal parasites. RESULTS The overall prevalence of any helminth and protozoa infections was 13.1% 53/406) and 22.4% (91/406) respectively. The predominant parasites were Giardia lamblia (13.8%), Ascaris lumbricoides (11.3%), Entamoeba histolytica/dispar (9.4%), Trichuris trichiura (3.9%), Entamoeba coli (1.5%) and hookworm (0.2%). Prevalence of co-infection with any helminths or protozoan was 2.7%. About 10.8% (44/406) and 20.7% (84/406) children were infected with single species of helminth and protozoan parasites. All helminth infections were light, with a mean intensity of 592 egg per gram. Intensity of any protozoan infections was heavy 62.6% (57/406). Dirt floors in the household (aOR = 2.22, p = .046), dirty toilets (aOR = 2.33, p=.014), water from communal taps (aOR = 0.27, p=.019), parent's education level (aOR=0.27, p=.032) and parent's earning (aOR =3.34, p=.007) were factors significantly associated with intestinal parasites. CONCLUSION The study found both helminth and protozoan parasites to be prevalent among pre-school aged children in Kibera. Intervention measures including education on the improvement of hygiene and health, socio-economic conditions, sanitation, and provision of safe drinking water could reduce the prevalence of these infections.

Abstract
There is paucity of studies at community level on prevalence of intestinal parasitic infection among under 18 years age group. This cross-sectional community-based research aimed to determine the prevalence of intestinal worm infections and its associated risk factors among 1 to 18 years age group in Puducherry, India. Sociodemographic, behavioral and other associated factors were collected using a structured questionnaire. One stool sample was collected from each participant and examined using direct (saline/iodine wet mount) and concentration (floatation/sedimentation) microscopic techniques. Log binomial regression analysis was used to find the factors independently associated with intestinal parasitic infection. Of 187 participants who provided the stool sample, 25 (13.4%) had at least one of the parasitic infections and among them 12 (6.4%) had Soil Transmitted Helminth infection (STH) and 13 (6.9%) had intestinal protozoan parasites. Parasitic infection is marginally higher among 1 to 7 years age group (14.4%) compared to 8 to 18 years age group (12.1%). After adjusting for confounding, urban residence (APR = 3.3, 95% CI 1.4-8.0) and open-air defecation (APR = 3.3, 95% CI 1.4-7.5) were significantly associated with intestinal parasitic infections. One out of eight children had any of the parasitic infection and nearly 50% of parasitic infections were caused by STH. Those children residing in urban areas and practice of open-air defecation had higher prevalence of parasitic infection.

Abstract
Present study was conducted among school children to recognize the prevalence of IPIs in rural communities of district Dir Lower, Pakistan. A sum of 324 samples of stool were collected (210 boys and 114 girls). Used direct smear method and formol ether sedimentation concentration technique for processing the samples. The result shows that 82% (n=266) were found infected comprised 64.8% male and 35.1% females. Children of the age group 10 to 12 years were found extremely infected 94.2% while 4-6 year age group were having minimum ratio of infection 72%. Current study shows mono parasitism in 50.6% of the students while 22.2% were infected with 2 species and 7.40% were infected with three species of parasites. Seven species of intestinal parasites were reported include Ascaris lumbricoid in male (n=122) 58.0% and in female (n=65) 57.0% followed by Hook worm (n=88) 41.9% and (n=44) 38.5%; Tania saginata (n=44) 20.9% and (n=24) 21.0%; Entrobius vermicularis (n=32) 15.2% and (n=16) 14.0%; Trichuris trichura (n=25) 11.9% and (n=22) 19.2%; Hymenolepis nana (n=24) 11.4% and (n=18) 15.7% and Entameoba histolytica (n=16) 7.61% and (n=14) 12.2% in male and females respectively. The study indicates that most occurring intestinal parasite in the current study were Ascaris lumbricoides 58.0% (n=122) followed by hookworms 41.9% (n=88). Male students were more infected than females in the present study.

Elmonir W, Elaadli H, Amer A, El-Sharkawy H, Bessat M, Mahmoud SF, Atta MS, El-Tras WF. Prevalence of intestinal parasitic infections and their associated risk factors among preschool and school children in Egypt. PLoS One 2021; 16:e0258037. [PMID: 34587187 PMCID: PMC8480785 DOI: 10.1371/journal.pone.0258037] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 09/16/2021] [Indexed: 12/13/2022] Open
Abstract
Intestinal parasitic infections (IPIs) are among the major public health problems globally, particularly in developing countries like Egypt. This study aimed to evaluate prevalence and risk factors associated with IPIs among preschool and school children in Egypt. A cross-sectional study was conducted on 996 randomly selected preschool and school-aged children in Gharbia governorate during January to April 2018. Stool specimens were examined for the presence of the parasite by direct smear and the formol-ether concentration methods. The overall prevalence of IPIs was 46.2%. Entamoeba histolytica and Ascaris lumbricoides were the most predominant parasites (12.7% per each). This is followed by Enterobius vermicularis (8.6%), Giardia lamblia (7.1%), Cryptosporidium parvum (1.5%), Heterophyes heterophyes (1.4%), Hymenolepis nana (0.7%), Hookworms (0.6%), Fasciola hepatica (0.5%) and Dipylidium caninum (0.4%). Infected children with no symptoms (26.8%) were significantly (P < 0.001) more frequent than those with medical complaint (19.4%). Socio-demographic predictors of IPIs were preschool age (OR = 4.9; P < 0.001; 95%CI 3.3-7.3), living in rural dwellings (OR = 1.96; P < 0.001; 95%CI 1.5-2.5), and belonging to a low-income family (OR = 4.7; P < 0.001; 95%CI 2.3-9.3). The absence of safe drinking water, lack of hand washing (after soil contact, or before meals, or after toilet usage), and eating unwashed vegetables were risk factors for IPIs in the study region (OR = 1.3-6.9, P < 0.001 -P = 0.05). Higher odds for exposure to potential zoonotic parasites were evident in children with pets in their homes for G. lambia and D. caninum (OR = 2.1-8.3; P = 0.02 -P = 0.04), children having household reared ruminants for C. parvum (OR = 10.4; P < 0.001), and children that play with stray animals for E. histolytica and Hookworm (OR = 1.8-6.3; P = 0.04 -P = 0.05)compared to other children with no animal contact. The present study highlights the importance of periodic screening and treatment of IPIs in children, deworming companion animals, and public education for effective prevention of IPIs in children in Egypt.

Infant Anthropometry and Growth Velocity Before 6 Months are Associated with Breastfeeding Practices and the Presence of Subclinical Mastitis and Maternal Intestinal Protozoa in Indigenous Communities in Guatemala. Curr Dev Nutr 2021; 5:nzab086. [PMID: 34585057 PMCID: PMC8460162 DOI: 10.1093/cdn/nzab086] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 05/21/2021] [Accepted: 05/31/2021] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND The possibility that maternal health status and breastfeeding practices contribute to growth faltering before 6 mo is underexplored. OBJECTIVES This longitudinal study investigated whether indicators of subclinical mastitis (SCM) and breast inflammation, maternal fecal-oral contamination, and/or breastfeeding practices were associated with infant anthropometry or growth velocity before 6 mo. METHODS Indigenous Mam-Mayan mother-infant dyads (n = 140) were recruited. Breast milk was collected at early (<6 wk) and established (4-6 mo) lactation when maternal and infant anthropometry were measured. Milk Na:K ratio as an indicator of SCM and concentrations of 4 proinflammatory cytokines were measured. Maternal stool samples were examined for the presence of intestinal parasites including nonpathogenic protozoa (Endolimax nana, Iodamoeba bütschlii, Entamoeba coli, Blastocystis hominis). Questionnaires characterized breastfeeding and hygiene practices. Multiple linear regression identified factors associated with infant growth attainment [weight-for-age z-score (WAZ), length-for-age z-score (LAZ), and head circumference-for-age z-score (HCAZ)] and growth velocity (expressed as change per day from early to established lactation). Multiple logistic regression identified factors associated with increased odds of underweight, stunting, and low head circumference at both lactation stages. RESULTS A higher Na:K ratio, individual nonpathogenic protozoa, and specific breastfeeding and hygiene practices were associated with impaired growth before 6 wk and at 4-6 mo in exclusively breastfed infants. Growth velocity for weight was inversely associated with Entamoeba coli but cranial growth was associated positively with Iodamoeba bütschlii whereas feeding colostrum in early lactation was protective and decreased the odds of an HCAZ < -2 SD. Finally, the presence of SCM in early lactation increased the likelihood of both WAZ < -2 SD and LAZ < -2 SD by 6 wk. CONCLUSIONS Prevention of SCM can improve early infant weight, but measures that promote the feeding of colostrum and reduce exposure to fecal-oral contamination might be required to minimize infant growth faltering in breastfed infants.

Abstract
Background The study investigated intestinal parasitic infestations (IPIs) and possible risk factors associated with asymptomatic children under five (5) years in five (5) selected communities in the Ho Municipality. Methods The study design was cross- sectional, with a simple random sampling technique involving 150 asymptomatic children under 5 years from 5 selected communities (Klave, Hoe, Freetown, Dave and Godokpe) in the Ho Municipality. A questionnaire was used to obtain socio-demographics and other relevant parameters. Direct wet preparation, formol-ether concentration and Modified ZN staining techniques were used for the identification of intestinal parasites from participants' stool samples. The Fisher's exact test and binary logistic regression analysis were used to determine the difference in IPIs proportions and assess the risk factors associated with IPIs respectively. Results The overall IPIs cases was 14% (21/150). Cryptosporidium spp was most predominant [5.3% (8/150)], followed by Entamoeba spp [3.3% (5/150)], Cyclospora cayetenensis [2.7% (4/150)], Ascaris lumbricoides [1.3% (2/150)], Giardia lamblia [0.7% (1/150)] and Strongyloides stercoralis [0.7% (1/150)]. Children in rural communities (23.4%) recorded significantly higher case rate compared to those in urban communities (9.8%0), (p=0.04). Lower educational attainment of mother [OR=0.55, 95% CI (0.37 – 0.83), p-value = 0.015] and residence in rural communities [OR = 0.53, 95% CI (0.33–0.88)], p-value = 0.025] were significantly associated with IPIs. Conclusion Asymptomatic IPIs are quite prevalent among children under 5 years in the Ho Municipality. The study thus recommends active sensitization programs for parents/guardians on preventive measures and school health programs should be instituted in rural communities.

Abstract
Background Intestinal parasitic infections are closely associated with low household income, poor personal and environmental sanitation, and overcrowding, limited access to clean water, tropical climate and low altitude. Street dwellers and prisoners are forced to live in deprived situations characterized by inadequate facilities. Therefore, this study aimed to estimate the pooled prevalence and associated factors of intestinal parasitic infections among street dwellers and prison inmates. Method Study searches were carried out in Electronic data bases such as PubMed/Medline, HINARI, EMBASE, Science Direct, Scopus, Google Scholar and Cochrane Library. Studies published only in English and have high quality Newcastle Ottawa Scale (NOS) scores were included for analysis using Stata version 14 software. Random-effects meta-analysis model was used for analysis. Heterogeneity was assessed using the Cochrane’s Q test and I2 test statistics with its corresponding p-values. Moreover, subgroup, sensitivity analyses and publication bias were computed. Result Seventeen eligible studies consist of 4,544 study participants were included. Majority of the study participants were males (83.5%) and the mean age of the study participants was 25.7 years old. The pooled prevalence of intestinal parasitic infections among street dwellers and prison inmates was 43.68% (95% CI 30.56, 56.79). Sub-group analysis showed that the overall pooled prevalence of intestinal parasitic infections among prison inmates and street dwellers was 30.12% (95%CI: 19.61, 40.62) and 68.39% (95%CI: 57.30, 79.49), respectively. There was statistically significant association between untrimmed fingernail and intestinal parasitic infections (AOR: 1.09 (95%CI: 0.53, 2.23). Conclusion In this study, the pooled prevalence of intestinal parasitic infections among street dwellers and prison inmates was relatively high. Fingernail status had statistically significant association with intestinal parasitic infection. The prevention and control strategy of intestinal parasitic infection should also target socially deprived segment of the population such as street dwellers and prison inmates.

Abstract
Background. Intestinal parasites are still a serious public health problem and important cause of morbidity and mortality all over the world, particularly in developing countries. Unfortunately, pre-school children are more susceptible to infection. However, information is scarce in the study area. Thus, this study aimed to assess the prevalence of intestinal parasitosis and associated factors among children aged 6 to 59 months in Northcentral Ethiopia. Methods. An institutional-based cross-sectional study was carried out at Mekane Eyesus primary hospital from June 10 to November 30, 2020. Stool samples were collected from 322 children and examined by using direct wet mount and formal ether concentration techniques. The data were entered and analyzed using EPI Info v7 and SPSS v23 statistical software, respectively. Both bivariable and multivariable logistic analysis was carried out and potential associated factors were identified based on adjusted odds ratio with 95% confidence interval and P-value <.05. Results. The prevalence of intestinal parasitosis was 18.0% (95% CI: 14.0%-22.0%). A total of 4 parasites were examined and the dominant parasite was E. histolytica/dispar (8.1%) followed by A. limbricoide (4.7%). Children with irregular trimming of fingernails (AOR = 3.14, 95% CI: 1.59-6.21), and child who have habit of eating unwashed fruits/vegetables (AOR = 3.80, 95% CI: 1.14-12.82) were strongly associated with IPIs. Conclusions. Protozoa parasites are most common cause of diseases in children. The study identified some preventable and modifiable factors to address the prevalence of IPIs. Additionally, improving mothers/guardians awareness about source of infection and mode of transmission is necessary.

Abstract
Co-infection of intestinal parasitic infections (IPIs) and Campylobacter spp. are public health problem in both developing and developed countries. This study was conducted to determine prevalence of IPIs and Campylobacter spp. among children with gastrointestinal disorders in Tehran. In this descriptive cross-sectional survey, 283 fresh stool samples were collected from all individuals and examined by standard parasitological methods including direct slide smear, formalin-ether concentration, trichrome staining, modified Ziehl-Neelsen staining, and chromotrope 2R staining techniques were used for detection of intestinal protozoa and helminths. Furthermore, culture and multiplex-PCR were also used to identify the species of Campylobacter. Data analysis was performed using SPSS version 16. IPIs were detected microscopically in 22.26% of the total study population, with a higher prevalence in Giardia duodenalis (7.06%) and Blastocystis hominis (7.06%). Campylobacter were detected molecularly in 14.8% (95.2% of C. jejuni vs. 4.8% of C. coli) of the total study populations; of these, 3.5% had co-existence with IPIs colonized patients. Our results showed a relatively high prevalence of IPIs and Campylobacter in children with diarrhea. Further research is needed to better understand their co-infection and ensure future advances in clinical trials, testing, and development of therapeutic approaches for these pathogens.

Abstract
Context: Intestinal parasitosis (IP), a group of diseases caused by one or more species of protozoa and helminths, is still considered a neglected tropical disease and a public health concern in India. Poor sanitation and unhygienic conditions largely contribute to sustained transmission, primarily among children, adversely affecting health and development. The problem needs area-specific assessment and interventions. Aims: The present study aimed at determining the prevalence of IP and its correlates among under-five children in a rural community of Purba Bardhaman district, West Bengal, India. Settings and Design: A descriptive cross-sectional study was conducted in Bhatar Block of Purba Bardhaman district. Subjects and Methods: Mothers/caregivers of 294 under-five children (selected through multistage sampling) were interviewed for background characteristics at the household level, and stool samples from each child were collected, transported, and examined for ova/parasite/cysts following standard guidelines. Statistical Analysis Used: Statistical analysis of the data obtained was done using SPSS (V20). Results: The overall prevalence of IP was 17.0%. Majority of the intestinal parasites were protozoa (42, 84%), of which the most common was Giardia lamblia (24, 48.0%). Age of the child and practice of defecation showed a significant association with IP on logistic regression. Conclusions: Protozoa, mainly G. lamblia, contributes for majority of intestinal parasitic infections among the study population, and children belonging to the age group of 25–60 completed months and with open-field defecation practice have higher risk of acquiring them.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) and intestinal parasites co-infections are the most common causes of clinical illness and death, especially for children living in resource constrained setting. Therefore, the aim of this study was to determine the prevalence and associated factors of intestinal parasites among highly active anti-retroviral therapy (HAART) initiated children. METHODS Cross-sectional study was conducted among 255 HAART initiated HIV-infected children at the University of Gondar Comprehensive Specialized Hospital from January to April 2020. Socio-demographic characteristics were collected using a structured questionnaire via a face-to-face interview. Clinical data of the children were collected by reviewing the medical records. Venous blood was collected for complete blood counts, viral load determination, and blood film examination. Flotation concentration technique was done in addition to direct wet mount for parasitological examination. Bi-variable and multi-variable logistic regression analysis were used to check the presence of significant association, and P-value<0.05 was considered as statistically significant. RESULTS The overall prevalence of intestinal parasite infection (IPI) among the study participants was 22.4% (95% CI=17-28%). The presence of opportunistic infection (AOR=2.09 95% CI=1.81-5.43), no eating under-cooked animal products (AOR=0.38 95% CI=0.16-0.94), male sex (AOR=0.45 95% CI=0.22-0.90), viral load rate >1,000 copies/mL (AOR=1.80 95% CI=1.67-4.19), and cytopenia (AOR=2.71 95% CI=1.59-12.25) showed significant association with the prevalence of IPI. CONCLUSION Entamoeba histolytica and Ascaris lumbricoides were the most prevalent intestinal parasites among HAART initiated children. Among HAART initiated children, IPI were associated with gender, cytopenia, viral load, undercooked animal products, and the presence of opportunistic infections. Therefore, health education, prompt treatment, and regular deworming should be implemented to alleviate the burden of intestinal parasites in HIV-infected children.

Prevalence and Associated Risk Factors of Human Intestinal Protozoan Parasitic Infections in Ethiopia: A Systematic Review and Meta-Analysis. J Parasitol Res 2020; 2020:8884064. [PMID: 33083045 PMCID: PMC7556079 DOI: 10.1155/2020/8884064] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 07/25/2020] [Accepted: 09/22/2020] [Indexed: 12/15/2022] Open
Abstract
Background Human intestinal protozoan parasitic infections (HIPPIs) are a series of public health problems in developing countries like Ethiopia. The overall prevalence of HIPPIs in Ethiopia is not known. Therefore, this systematic review and meta-analysis study is aimed at determining the overall prevalence of HIPPIs in Ethiopia. Methods Articles written in English were searched from online public databases. Searching terms used were "prevalence," "intestinal protozoan parasite," "associated factors," and "Ethiopia." We used Stata version 14 for meta-analysis and Cochran's Q test statistics and the I 2 test for heterogeneity. Result A total of 286 articles were reviewed, but only 45 of them fulfilled the inclusion criteria. The pooled prevalence of HIPPIs in Ethiopia was 25.01% (95% CI: 20.08%-29.95%) where Entamoeba histolytica/dispar is the most prevalent (14.09%, 95% CI: 11.03%-17.14%) followed by Giardia lamblia (10.03%, 95% CI: 7.69%-12.38%) and Cryptosporidium spp. (5.93%, 95% CI: 2.95%-8.91%). This meta-analysis showed that family size (OR: 3.7, 95% CI: 1.45-5.85), source of drinking water (OR: 3.33, 95% CI: 1.30-5.36), open field defecation (OR: 2.91, 95% CI: 1.60-4.21), handwashing habit (OR: 2.82, 95% CI: 2.01-3.63), playing with soil (OR: 2.15, 95% CI: 1.01-3.29), the habit of eating raw vegetables (OR: 1.77, 95% CI: 1.03-2.51), and fingernail trimming (OR: 1.70, 95% CI: 0.89-2.25) were strongly associated with the HIPPIs in Ethiopia. High heterogeneity on the prevalence of HIPPIs was observed among studies within and among regions (I 2 > 99% and P ≤ 0.01). Conclusion The prevalence of HIPPIs was significantly high among the Ethiopian population. Family size, source of drinking water, open field defecation, handwashing habit, the habit of eating raw vegetables, and fingernail trimming habits were significantly associated with HIPPIs.

Abstract
Soil transmitted helminthes (STH) are among the major public health issues in tropical and sub-tropical countries infecting more than 2 billion humans worldwide. STH causes considerable morbidity in children, affecting their cognitive development and physical growth. Endemic areas with poor sanitation and limited access to good quality water supply have the highest burden of STH infection. Various approaches to reduce and control the worm infections include the intermittent deworming of children with anti-helminthic drugs. Individual patient management and population based studies can only be successful upon using the diagnostic techniques with high accuracy. The lack of reliable tools for the provision of correct diagnostic results about the status and intensity of infection is a major challenge, as these factors varies considerably in areas of low infection intensities. The techniques currently available for the diagnosis of parasitic infections show limited specificity and sensitivity and as such several techniques in combination are normally used in diagnosing the variety of parasite species infection. This review article was planned to study the prevalence, risk factors, and the available diagnostic techniques for soil and water transmitted helminthes infections in humans. This article also discussed the challenges in diagnosis, treatment, and management of worm infections particularly helminthes. The articles available online on important portals like google scholar, PubMed, Digital Libraries, PakMediNet, Science direct, and the Directory of Open Access Journals (DOAJ) were searched for inclusion of the data in this review study. Duplicate studies and irrelevant reports describing the general aspects of parasite infections were excluded. This review study provides a comprehensive report on the prevalence, accurate diagnostic, and chemotherapeutic protocols to reduce the burden of worms infections. WHO suggests the chemotherapy for worm infections as feasible and cost effective strategy in schools due to the lack of proper policy for the prevention of intestinal worms.

Prevalence of Intestinal Parasitic Infections and Associated Water, Sanitation, and Hygiene Risk Factors among School Children in Mwea Irrigation Scheme, Kirinyaga County, Kenya. J Trop Med 2020; 2020:3974156. [PMID: 32454837 PMCID: PMC7238387 DOI: 10.1155/2020/3974156] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2019] [Revised: 03/20/2020] [Accepted: 04/07/2020] [Indexed: 12/23/2022] Open
Abstract
School children bear a significant burden of intestinal parasitic infections. Because they spend most of their time at home and school, it is necessary to identify the key water, sanitation, and hygiene (WASH) factors associated with these infections in both environments. This was a cross-sectional survey conducted in Mwea West, Kirinyaga County. 180 primary school children aged 8–14 years were randomly selected from three schools (Mianya, Mbui Njeru, and Mukou primary schools). Questionnaires and checklists were administered and single stool samples were collected. Stool samples were microscopically examined for Schistosoma mansoni, soil-transmitted helminths, and protozoan infections. Data on WASH were obtained at home and school. The factors significantly associated with S. mansoni and intestinal protozoa infections in the school children were determined using univariable and multivariable logistic regression models reporting the odds ratio at 95% confidence intervals. The overall prevalence of S. mansoni and intestinal protozoa infections was 70.5% (95% CI: 59.1–84.3) and 32.7% (95% CI: 26.8–40.1), respectively. Only one case of STH (A. lumbricoides) was identified. The prevalence of coinfections of S. mansoni and intestinal protozoa infections was 22.8% (95% CI: 19.2–27.1). An increased prevalence of S. mansoni infection was associated with children above 12 years (aOR = 3.19, p=0.015), those in Mianya primary (aOR = 1.23, p=0.001), those in Mukou primary (aOR = 3.19, p=0.001), and reported behavior of wearing shoes at home (aOR = 1.67, p=0.010). However, handwashing behavior after defecation at home (aOR = 0.39, p=0.001) was protective against S. mansoni infection. For any protozoan infection, male children had increased odds of infection (aOR = 2.41, p=0.001) while use of wiping material (aOR = 0.55, p=0.019) and water contact (aOR = 0.32, p=0.001) was protective against intestinal protozoa infections. Infections with S. mansoni and any protozoa and their coinfection were present. Findings revealed that several hygiene factors were protective against infections while other were risk factors. Therefore, deworming should be complemented with behavior education on hygienic habits.

Intestinal parasitosis, anaemia and risk factors among pre-school children in Tigray region, northern Ethiopia. BMC Infect Dis 2020; 20:379. [PMID: 32460777 PMCID: PMC7251880 DOI: 10.1186/s12879-020-05101-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Accepted: 05/17/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Intestinal parasitic infections (IPIs) and anaemia are major health problems. This study assessed the prevalence of intestinal parasitic infections, anaemia and associated factors among pre-school children in rural areas of the Tigray region, northern Ethiopia. METHODS A community based cross-sectional study was conducted among 610 pre-school children in rural communities of Northern Ethiopia from June 2017 to August 2017. Stool specimens were examined for the presence of trophozoites, cysts, oocysts, and ova using direct, formal-ethyl acetate concentration, Kato-Katz, and Ziehl-Neelsen techniques. Haemoglobin was measured using a HemoCue spectrometer. RESULTS Among the 610 participating pre-school children in the study, the prevalence of IPIs and anaemia were 58% (95% conference interval (CI): 54.1-61.9%) and 21.6% (95% CI: 18.5-25.1%), respectively. Single, double, and triple parasitic infections were seen in 249 (41, 95% CI: 37-45%), 83 (14, 95% CI: 11-17%), and 22 (3.6, 95% CI: 2.4-5.4%) children, respectively. Of the seven intestinal parasitic organisms recorded from the participants, Entamoeba histolytica/dispar was the most prevalent 220 (36.1%) followed by Giardia lamblia 128 (20.1%), and Hymenolepis nana 102 (16.7%). Mixed infections were common among G. lamblia, E. histolytica/dispar and Cryptosporidium spp. oocyst. Intestinal parasitic infection prevalence increased from 47% in children aged 6-11 months to 66% in those aged 48-59 months; the prevalence ratio (PR) associated with a one-year increase in age was 1.08 (95% CI: 1.02-1.14, p = 0.009). Age-adjusted prevalence was higher in children who had been dewormed (PR = 1.2; 95% CI: 1.00-1.4, p = 0.045), and lower in households having two or more children aged under five (PR = 0.76, 95% CI: 0.61-0.95, p = 0.015). Anaemia rose from 28% in children aged 6-11 months to 43% in those aged 12-23 months, then fell continuously with age, reaching 7% in those aged 48-59 months. Age adjusted, anaemia was more prevalent in households using proper disposal of solid waste (PR = 1.5, 95% CI: 0.1-2.10, p = 0.009) while eating raw meat (PR = 0.49, 95% CI: 0.45-0.54, p = 0.000), any maternal education (PR = 0.64 95% CI: 0.52-0.79, p = 0.000), and household water treatment (PR = 0.75, 95% CI: 0.56-1.0, p = 0.044) were associated with lower prevalence of anaemia. CONCLUSIONS More than half of the children were infected with intestinal parasites, while anaemia prevalence was concentrated in the 12-23 month age group. This study has identified a number of potentially modifiable risk factors to address the significant prevalence of IPIs and anaemia in these children. Improvements in sanitation, clean water, hand hygiene, maternal education could address both short and long-term consequences of these conditions in this vulnerable population.

Parasite Epidemiol Control 2020; 9:e00136. [PMID: 31993514 PMCID: PMC6976929 DOI: 10.1016/j.parepi.2020.e00136] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 01/05/2020] [Accepted: 01/05/2020] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Intestinal helminthic infections are among the most important global socioeconomic and health problems. This study aimed to estimate the frequency of intestinal parasites in 366 children aged 2 to 15 years referred to the main pediatric health center of Lorestan Province, Iran. METHODS Microscopic analysis was performed on 366 stool samples. We applied direct smear, scotch tape, and formol-ether methods. Moreover, a questionnaire was filled in by parents or guardians of the children. RESULTS The results showed that 36 children (9.8%) were infected with at least one or more intestinal parasites. The most prevalent parasites were Enterobius vermicularis (6.8%), Hymenolepis nana (1.9%), and Ascaris lumbricoides (0.55%), in the order of their appearance. Statistical analysis showed that several risk factors were significantly associated with the prevalence intestinal helminthic parasites, including male sex (OR = 2.9; 95% CI: 1.2-6.2; p < 0.05), residing in rural regions (OR = 4.2; 95% CI: 2.1-10.6; p < 0.001), no handwashing habit before eating (OR = 5.2; 95% CI: 2.2-12.5; p < 0.001), and consuming raw or unwashed vegetables and fruits (OR = 4.8; 95% CI: 2.3-11.2; p < 0.001). CONCLUSION The present study showed a high overall frequency of intestinal helminthic infections among the children in Lorestan province, Iran. The results of the risk factor analysis suggest that improving environmental hygiene and health education would be important for effective control of intestinal parasitic infections.

Epidemiology of intestinal parasitic infections in preschool and school-aged Ethiopian children: a systematic review and meta-analysis. BMC Public Health 2020; 20:117. [PMID: 31992252 PMCID: PMC6988312 DOI: 10.1186/s12889-020-8222-y] [Citation(s) in RCA: 37] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2019] [Accepted: 01/15/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Numerous studies have been carried out on assessing the prevalence of intestinal parasites infections (IPIs) amongpreschool and school-age children in Ethiopia, but there is lack of study systematically gathered and analyzedinformation for policymakers. Therefore, the aim of this systematic review and meta-analysis was to provide a summary on prevalence, geographical distribution and trends of IPIs among preschool and school-age childrenin Ethiopia. METHODS The search were carried out in Medline via PubMed, Scopus, Science Direct, Web of Science, and Google Scholar from 1996to July2019 for studies describing prevalence of IPIs among preschooland school-age children. We conducted meta-regression to understand the trends and the source of heterogeneity and pooled the prevalence using 'metaprop' command using STATA software version 14. RESULTS Eighty-three(83) studies examining 56,786 fecal specimens were included. The prevalence of IPIs was 48%(95%CI: 42 to 53%) and showedsignificantly decreasing trends 17% (95% CI: 2.5 to 32%) for each consecutive 6 years) and was similar in males and females. The pooled prevalence in years 1997-2002, 2003-2008, 2009-2014 and > 2014 was 71% (95% CI: 57 to 86%), 42% (95% CI: 27 to 56%), 48% (95% CI: 40 to 56%) and 42% (95% CI: 34 to 49%), respectively. Poly-parasitism was observed in 16% (95% CI: 13 to 19%,) of the cases. CONCLUSION Intestinal parasite infections are highly prevalent among preschool and school-age children and well distributed across the regional states of Ethiopia. Southern and Amhara regional states carry the highest burden. We observed significant decreasing trends in prevalence of IPIs among preschool and school-ageEthiopian children over the last two decades. Therefore, this study is important to locate the geographical distribution and identified high risk areas that should be prioritized further interventions, which complement global efforts towards elimination of IPIs infections by 2020.

Abstract
The aim of the present study is to perform a retrospective analysis of the prevalence of intestinal parasitic infections among the Bulgarian population over the period 2015 - 2017. The study involved all Bulgarians and foreign nationals residing in the country who had been tested for intestinal protozoa and helminths. A total of 23,785 infections have been revealed, of which 17,712 (74.47 %) were helminth and 6,073 (25.53 %) protozoan invasions. Enterobiasis was found to be the most prevalent among patients infected with intestinal helminths (81.75 %), while giardiasis (62.05 %) was the most common among those diagnosed with protozoan infections. In spite of improved living conditions and increasing public health awareness, parasitic diseases in general, and intestinal parasitic infections in particular, still represent a significant part of the overall morbidity in Bulgaria, thus posing a major issue for the public health care system.

Abstract
Giardia duodenalis is considered a highly diverse organism that infects a variety of mammalian hosts. Giardiasis is a significant public health problem in Iran. The purpose of this study was to investigate the occurrence of Giardia duodenalis (G. lamblia, G. intestinalis) infections in humans residing in the Guilan province of Iran. Stool samples were collected during 12 months from 8356 individuals that had been referred to certain hospitals in the capital city of Rasht in the Guilan province, of which 4126 were males and 4230 were females. The samples were separated into three groups according to patient age: group A 1-9 years old (n = 483); group B 10-19 years old (n = 491); and group C greater than 20 years old (n = 7382). The wet mount technique was performed directly on 8356 fecal samples for microscopy. Samples were examined using a saline and iodine direct smear technique in order to confirm the presence of G. duodenalis. The results indicated that 2.5% (206/8356) of the samples were identified as positive for G. duodenalis. A total of 30% of the infected patients (n = 62) had no symptoms. In symptomatic cases, the most common symptoms (46%, n = 95) were abdominal cramps and bloating. Twenty-four percent of patients (n = 50) had cramps, bloating, nausea, and diarrhea. Sixty positive samples were sent for G. duodenalis genotyping based on the amplification of the gdh gene. Forty-one PCR products were successfully selected and sequenced, where 38 (92.6%) samples were identified as genotype A/subgenotype II and in three samples (7.4%) genotype B/subgenotype IV. Genotype A-II had a dominant prevalence as compared to the genotype B-IV samples that were identified in the study. Based on the samples provided by the regional teaching hospitals and subsequent sample analysis, the authors concluded that assemblage A-II is most likely the most common Giardia subgroup infection in the Guilan region. Assemblages have been reported in both humans and animals; however, further studies need to investigate the role of domestic animals and water reservoirs as potential sources of Giardia infection in the Guilan region.

Prevalence and risk factors of intestinal parasitic infestations among preschool children in Sekota town, Waghimra zone, Ethiopia. BMC Pediatr 2019; 19:437. [PMID: 31722686 PMCID: PMC6854779 DOI: 10.1186/s12887-019-1774-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2019] [Accepted: 10/07/2019] [Indexed: 11/23/2022] Open
Abstract
Background Intestinal parasitic infestations triggered considerable gastrointestinal morbidity, malnutrition, and mortality worldwide. In particular, young children in developing countries affected most. Helminthiasis infestation accounts for 10–20% of prevalence on preschool children worldwide. Unfortunately, small children below 5 years are uniquely susceptible to intestinal parasitic infestations in poor communities. This is because of children’s behavior like playing with soil and putting hand -to- mouth habit. Thus, the aim of this study was to assess the prevalence and risk factors of intestinal parasitic infestations among preschool children in Sekota town, Ethiopia. Methods A community-based cross-sectional study was carried out on 378 preschool children in Sekota town from February 15 – March 10/2019. Stool specimens were collected and examined for intestinal parasites using wet mount and formal ether concentration technique. The risk factors of intestinal parasites were assessed using a pretested structured questionnaire. The data were entered and analyzed using Epi-data version 4.2.0.0 and SPSS-version 23 statistical software respectively. Both bivariable and multivariable analysis was carried out, and potential co-linearity was tested for closely similar variables. Variables with P value less than 0.05 in multivariable analysis was considered as statistically significant and reported with 95% CI and odds ratio. Results The prevalence of intestinal parasitic infestations in Sekota town on wet mount and formal ether concentration techniques was 83(21.9%), (95% CI, 17.7–26.3%) and 113(29.9%), (95% CI, 25.1–34.8%) respectively. In multivariable analysis, not taking medication as periodical deworming (AOR, 95% CI), (2.5, 1.5–4.3), presence of animals in the living room (AOR, 95% CI) (3.1, 1.8–5.3), and being a government employee as an occupation (AOR, 95% CI), (3.4, 1.1–10.0) were increasing the odds of intestinal parasitic infestations. Conclusions The prevalence of intestinal parasitic infestations in Sekota town is high, which is a public health problem. The risk factors that contributed to intestinal parasitic infestations in this study were preventable and modifiable. Therefore, the concerned bodies need to emphasis on periodical deworming and keeping animals in separate room.

Objectives The main aim of this study was to assess the Magnitude of intestinal parasitic infections and associated factors among food handlers working at Woldia University Student’s cafeteria, Northeastern Ethiopia. Institutional based cross-sectional study was conducted among 256 study participants in Woldia university student’s cafeteria, Northern Ethiopia. Systematic random sampling method was used to select the study participants. Data was collected using a standardized questionnaire by direct interviewing of study participants. Logistic regression was carried out to identify factors associated with intestinal parasitic infections. Results A total of 256 food handlers were enrolled making the overall magnitude of the intestinal parasite which was stool specimens positive for different diagnostic stages of parasites was found to be 43 (16.8%). Entamoeba histolytica/dispar was the most prevalent parasites 14 (5.5%), followed by Giardia lamblia 10 (3.9%). Lack of food safety training (AOR = 6.58; 95% CI 2.46–17.62), no regular medical checkup (AOR = 2.41; 95% CI 1.47–4.24), no handwashing practice after toilet by soap (AOR = 3.24; 95% CI 1.28–8.19), no handwashing practice before eating by soap (AOR = 4.03; 95% CI 1.64–9.91) and haven’t food preparation license (AOR = 6.13; 95% CI 2.18–17.22) were significantly associated with parasitic infection among food handlers.

Abstract
INTRODUCTION Although parasitic infections lead to extracorporeal iron loss resulting in iron deficiency anaemia (IDA), data associating IDA with parasitic infections in the first two years of life are limited. We sought to evaluate the prevalence and severity of anaemia and IDA during this period and to investigate the association between intestinal parasitic infections and IDA. METHODOLOGY Data was collected under MAL-ED study protocol in Bauniabadh slum of Dhaka, Bangladesh. The presence of parasites in stool was detected using wet preparation microscopy at 7, 15, and 24 months. Anaemia was defined as serum haemoglobin < 11 g/dL and IDA was defined by serum haemoglobin < 11 g/dL, serum ferritin < 12 g/L and soluble transferrin receptor > 8.3 mg/L. Logistic regression was done to quantify the relation between stool parasite and IDA separately on samples collected at 7, 15 and 24 months. RESULTS 265 children were enrolled after birth and samples were collected at 7, 15 and 24 months. Anaemia was detected at 7, 15 and 24 months in 117 (48.8%), 106 (44.2%) and 67 (27.9%) cases whereas IDA was found in 15 (6.3%), 47 (19.6%) and 39 (16.3%) cases, respectively. Iron deficiency anaemia at 24 months was significantly associated with Ascaris lumbricoides infection (OR 3.76; 95 % CI, 1.08-13.11). CONCLUSIONS The prevalence of anaemia and IDA in slum dwelling children of Dhaka is high and Ascaris lumbricoides infection was found to have a strong association with IDA at 24 months of age.

Abstract
BACKGROUND Intestinal parasitic infection is diversified illness and diseases caused millions morbidity among under-five children lives in developing countries particularly vulnerable rural communities. Deworming coverage in such community is low. The aim of this study was to determine the prevalence and associated risk factors of intestinal parasitic infections (IPIs) among under-five children live in and around Haro Dumal Town. METHODS Community-based cross-sectional study was conducted in 561 randomly selected under-five children from June to August, 2018. The stool samples were collected and examined by basic parasitological techniques. Data related to socio-demographic and risk factors were collected using a self administered questionnaire. Statistical data analysis was done using SPSS version 21 and the bivariate and multivariate logistic regression used to compute the association between variables. P-value of < 0.05 was statistical significance. THE RESULTS Of the 561 total under-five children, 216 (38.5%) were found to be infected with intestinal parasites. E.histolytica/dispar (15.3%) was the most prevalent parasite, followed by hook worm (14.4%) and T.trichuria (13.9%). Regarding risk factors, geo-phage [(AOR = 4.7; 95%CI: 2.0-10.4), P < 0.001], tungiasis [(AOR = 3.1; 95%CI: 1.1-6.6), P < 0.001], eating raw vegetable [(AOR = 1.3; 95%CI: 1.4-3.3), P < 0.001] were significantly associated with intestinal parasitic infections. CONCLUSION Intestinal parasitic infections (IPIs) were found to be highly prevalent in the study area. Hence, improving sanitation, controlling ecto-parasite such as tungiasis, provision of safe water and successful mass-deworming are important.

Abstract
BACKGROUND Tuberculosis and parasitosis are the widely distributed diseases in Ethiopia with the leading cause of mortality and morbidity, respectively. There has been no information on the status of co-infections of tuberculosis and parasitosis in Oromia Zone of Amhara Region and South Wollo, Ethiopia. Hence, this study primarily focuses on determining the status of tuberculosis and parasitosis co-infections and associated factors. METHODS The study was conducted in Oromia Special Zone of the Amhara Regional State and South Wollo Zone, northeastern Ethiopia from April 2015 to January 2017. Tuberculosis cases confirmed by health personnel at the health institutions were the source of the study sample. In a cross-sectional study 384 smear positive pulmonary and extra-pulmonary tuberculosis cases were recruited. Faecal specimens provided by the study participants were examined for parasitic co-infections using direct saline microscopic test, Kato-Katz and concentration techniques. Nutritional status was determined using body mass index and mid-upper arm circumferences. Data were analyzed using descriptive statistical methods and Pearson chi-square. RESULTS Tuberculosis and parasitosis co-infection prevalence was 10.8%, and the proportion of intestinal helminths accounted for 9.7% while intestinal protozoa accounted for 1.9%. Cases with single parasitic infection was 89.3% among co-infected individuals. Co-infection of both disease was not significantly associated with gender and age (P > 0.05). The prevalence of undernutrition was 58.6% as determined using body mass index and 73.0% as determined using mid-upper arm circumference with no significant association with gender. Among all forms of tuberculosis cases (384) screened for the study, the bacterial positivity was relatively more common in males (55.5%) than females (44.5%). Tuberculosis lymphadenitis was found to be the most prevalent (85.9%) form of extra-pulmonary tuberculosis with cervical adenopathy (75.3%) being the commonly existing disease. CONCLUSIONS The rate of helminthic co-infection is predominantly high than that of intestinal protozoa. Single parasitic co-infection was more common than double or multiple co-infections. Both body mass index and mid-upper arm circumference anthropometric parameters revealed greater risk of undernutrition in tuberculosis patients. Thus, screening and prompt treatment of parasites in tuberculosis patients and a support of nutritional supplementation for malnourished tuberculosis patients should be further studied which might enhance the disease treatment and minimize the risk of its complexity.

Abstract
BACKGROUND Environmental, social, geographical, and other factors could affect the distribution of intestinal parasites. Parasitic infections would impose on health and social problems like mal-absorption, diarrhea, impaired work capacity, and reduced growth rate. However, there is a scarcity of information regarding the prevalence of intestinal parasites and associated factors in the study area. METHODS Institution based cross-sectional study was conducted among 310 study participants from April-May, 2017. Study participants were selected using a systematic random sampling technique. EPI Info version 7 and SPSS version 20 were used to enter and analyze the data. Both bivariate and multivariate logistic regression analyses were computed. In multivariate analysis, variables with P-value < 0.05 were considered statistically significant. RESULTS In this study, the mean age of participants was 29.25 Months. The overall prevalence of intestinal parasites was 18.7% (95% CI = 14.4-23.3). Children who rarely feed fresh meal (AOR = 7.74, 95% CI: 1.61, 7.84), Children whose nails were sometimes trimmed (AOR = 3.41, 95% CI: 2.20-10.28), children who had no clean playing ground (AOR = 2.43, 95% CI: 1.25-5.18), and children who had open defecation of the family (AOR = 3.40, 95% CI: 1.27-10.86) were significantly associated with intestinal parasitic infections. Among the intestinal parasites, 31(53.5%) were G.lamblia (Giardia lamblia) and 21(36.2%) were E. histolytica/E. dispar/E. moshkovskii. CONCLUSION In this study, the prevalence of intestinal parasites was found low compared with the WHO annual or biannual population prevalence and treatment. However, strengthening of health education about food, personal and environmental hygiene of both children and mothers/guardians is crucial to limit the transmission. Besides, improving mothers/guardian awareness about the mode of intestinal parasites transmission is necessary.

Abstract
OBJECTIVES Parasitic infections such as toxoplasmosis, hydatidosis, and cysticercosis infect a large population worldwide. Toxoplasma gondii in the pancreas could damage the pancreatic cells. Hence, insulin secretion would be affected which leads to increased risk of diabetes. The present study was designed to investigate the cooccurrence of parasitic infections in patients with diabetes. METHODS A total of 256 confirmed parasitic serum samples were included in the study, of which 95 were positive for toxoplasmosis, 87 for hydatidosis, and 74 for cysticercosis infection. These samples were then analyzed for hyperglycemia. RESULTS In case of hydatidosis, the frequency of hyperglycemia was 14.94%, followed by cysticercosis (10.8%) and toxoplasmosis (8.42%). The frequency of insulin resistance was analyzed in these hyperglycemic samples. The coprevalence of diabetes was higher in case of hyperglycemic hydatidosis patient samples (11.49%), followed by cysticercosis (8.10%) while the coprevalence of diabetes was minimum (6.31%) in toxoplasmosis patients samples. Thus, the overall prevalence of diabetes with parasitic infections was 8.6%. CONCLUSION The study suggested the coexistence of hyperglycemia in hydatidosis, cysticercosis, and toxoplasmosis infected samples. However, higher prevalence of high glucose level was detected among hydatidosis infected samples. Thus, suggested individuals infected with hydatidosis were more susceptible for diabetes in comparison to toxoplasmosis and cysticercosis.

Abstract
Background Intestinal parasites cause significant morbidity and impact human development with an enormous global burden. Diagnosis of intestinal parasites by conventional methods has several limitations. The gauze filtration technique is a relatively simple method that has been shown to identify intestinal parasites with a high sensitivity and specificity. The aim of this study was to determine the diagnostic value of this technique as compared to more conventional methods in a large acclaimed laboratory within Pakistan. Methods A total of 50 stool samples collected for routine diagnostic workup from patients age between 2-70 years were collected from the parasitology section of the Aga Khan University Hospital Clinical Laboratory. A direct wet mount, sedimentation technique, and gauze filtration technique were performed on all of the stool samples, and the sensitivity, specificity, negative predictive value, and positive predictive value were analyzed. Results It was observed that the number of organisms observed by gauze filtration as compared to direct wet mount and sedimentation technique was higher for B. hominis, G. lamblia cysts and trophozoites, and I. bütschlii. Also, the detection rate was significantly higher for B. hominis and G. lamblia cysts using the gauze filtration technique. The sensitivity and specificity of the gauze filtration technique were found to be 95.8% and 100%, respectively. Conclusion There is a significantly better stool sample parasite detection rate using the gauze filtration technique as compared to the conventional sedimentation techniques. The utility of the gauze filtration technique seems economically and technically feasible for diagnostic laboratories in resource-limited settings.

Abstract
Objective Intestinal parasitic infection is a serious public health problem throughout the world particularly in developing countries. Like other countries in sub saran region epidemiological data regarding prevalence of intestinal parasites and their associated factors were limited in Ethiopia. So, the main objective of this study was to determine the prevalence of intestinal parasites and associated factors among under five children in Dessie Referral Hospital from August 1, 2017 to December 20, 2017. Results In this research a total of 232 under five children were involved. Out of these study subjects 36 (15.5%) were infected with at least one intestinal parasites. A total of five intestinal parasites were examined and the dominant parasite was E. histolytica 15/232 (6.5%) followed by H. nana 11/232 (4.7%). All age groups were affected by intestinal parasites but children who were at the age of below 2 years and at the age between 2 and 3 years were 4.7 times and 2.6 times at risk of acquiring infection with intestinal parasites in comparison at the age of 3–5 years children.
