Abstract
Background In people with human immunodeficiency virus infection, diarrhea is reportedly associated with significant morbidity and mortality. Therefore, the aim of this study was to determine the prevalence, antibiotic susceptibility pattern, and associated factors of enteric bacterial pathogens among HIV infected patients with diarrhea attending the antiretroviral treatment (ART) clinic of Dilla University Referral Hospital, southern Ethiopia. Methods This institutional-based cross-sectional study was conducted on 422 study participants attending at ART clinic of Dilla University Referral Hospital from March to August 2022. Demographic and clinical data were collected by using a semi-structured questionnaire. Stool specimens were inoculated on selective media like Butzller's medium and Xylose Lysine Deoxycholate (XLD) agar. Antimicrobial resistance pattern was assessed by using Kirby-Bauer disk diffusion techniques. Adjusted odds ratio (AOR) and 95% Confidence Interval (CI) was used to determine the presence of association. Results A total of 422 adult patients were enrolled in this study, 51.7% were females. The mean age of the study participants was 27.4 (±15.6 SD) years. The overall prevalence of enteric pathogens was 14.7% (95% CI=11.4-18.2). Shigella spp was the most prevalent organism. Being a farmer (AOR=5.1; 95% CI=1.4-19.1; p<0.015), the habit of hand washing after toilet (AOR=1.9; 95% CI=1.02-3.47; p<0.04), low CD4 cell count of <200 cells (AOR=2.22; 95% CI=1.15-4.27; p<0.02), and longer duration of diarrhea (AOR=2.68; 95% CI=1.23-5.85; p<0.01) were statistically associated. In total, 98.4% of enteric bacterial isolates were sensitive for Meropenem, whereas 82.5% were resistant against Ampicillin. Multidrug resistance was detected in 49.2% of enteric bacteria. Conclusion We found that enteric bacteria are common causative agents of diarrhea in immune-compromised patients. The high rate of drug resistance calls for escalating antimicrobial susceptibility testing before prescribing antimicrobial agent.

High carriage rate of intestinal parasites among asymptomatic HIV-seropositive individuals on antiretroviral therapy attending the tertiary care hospital in Varanasi, India. Indian J Sex Transm Dis AIDS 2021; 42:101-105. [PMID: 34909612 PMCID: PMC8628098 DOI: 10.4103/ijstd.ijstd_39_18] [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: 05/23/2018] [Revised: 12/22/2019] [Accepted: 03/24/2020] [Indexed: 11/04/2022] Open
Abstract
Introduction Infections by intestinal parasites (IPs) are prevalent among human immunodeficiency virus (HIV)-seropositive individuals. Although diarrhea is the usual manifestation, asymptomatic presentations are common. In such situations, the problem of parasitosis is often underestimated. This study was performed to assess the presence of IPs among asymptomatic HIV-seropositive patients. Materials and Methods A case-control study was designed, including stool samples from 75 asymptomatic HIV-seropositive patients and 75 seronegative patients with gastrointestinal discomfort. IPs was identified by microscopy and polymerase chain reaction (PCR) for Entamoeba spp, Cryptosporidium and Microsporidium spp. The data were statistically analyzed using the Chi-square test. Results The prevalence of IPs in HIV-seropositive cases (25.33%) was statistically significantly more (P < 0.05) than that of controls (4%). Helminths predominated in both the groups. PCR detected IPs in 5 (6.6%) additional microscopy-negative cases. The presence of IPs was associated with CD4 count <200 cells/μl. Conclusion The asymptomatic carriage of IPs in HIV patients poses an important reservoir in the community. To prevent transmission, frequent screening is needed.

Abstract
Purpose To study intestinal parasitosis and its association with viral load and CD4+ T cell count in HIV-infected individuals at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia. Methods A cross-sectional study was conducted from March to June 2019. Three hundred and sixteen study participants were selected using systematic random sampling technique. Sociodemographic and clinical data were collected using structured questionnaire. Stool samples were collected and examined using direct saline, formol ether concentration technique and modified acid fast staining. CD4+ T cell counts and viral load were determined by fluorescence-activated cell sorting (BD FACS) and COBAS Ampliprep/COBAS TaqMan HI2CAP assay, respectively. Data were entered into Epi Data 3.1 and transferred to SPSS version 20 software for analysis. Bivariable and multivariable analyses were performed using a binary logistic regression model. P values of less than 0.05 were considered statistically significant. Results The overall prevalence of intestinal parasitosis was 24.7% (78/316). The most commonly detected parasite was Cryptosporidium species with 5.4% (17/316), followed by Ascaris lumbricoides with 5.1% (16/316). There was a significant association with low CD4+ T cell count (AOR: 3.207; 95% CI: 1.237, 8.317), high viral load (AOR: 2.933; 95% CI: 1.326, 6.489), individuals aged 31–40 years (AOR: 0.305; 95% CI: 0.124, 0.751) and individuals aged 41–50 years (AOR: 0.261; 95% CI: 0.101, 0.671). Conclusion In this study, prevalence of intestinal parasitic infections was high and was associated with low CD4+ T cell count and high viral load. Therefore, screening of HIV patients, especially those with low CD4+ T-cell count and high viral load, particularly for opportunistic intestinal parasitic infections would be of utmost importance in the efforts to prevent and control opportunistic infections in HIV patients.

Abstract
The significance of opportunistic infections in immunocompromised patients and the enigmatic pathogenicity of Blastocystis directed us to conduct the first global systematic review and meta-analysis on Blastocystis prevalence, odds ratios (ORs), and subtypes distribution in various immunocompromised patients (HIV/AIDS, cancer and hemodialysis patients, as well as transplant recipients). The systematic searching procedure was done in Web of Science, PubMed, Scopus, and Google Scholar databases for relevant published literature until November 11, 2020. Random-effects model was utilized to calculate the weighted estimates and 95% confidence intervals (95% CIs). The computed pooled prevalence of Blastocystis inferred from 118 papers (128 datasets) on immunocompromised patients was 10.3% (95% CI: 8.7-12.2%), with 16.1% (95% CI: 11.3-22.2%), 12.5% (95% CI: 8.5-18%), 8.4% (95 % CI: 6.6-10.6%), and 6% (95% CI: 2.6-13.3%) for hemodialysis patients, cancer patients, HIV/AIDS patients, and transplant recipients, respectively. Based on 50 case-control studies (54 datasets), the highest ORs were associated with cancer [2.81 (95% CI: 1.24-6.38, P = 0.013)] and hemodialysis patients [2.78 (95% CI: 1.19-6.48, P = 0.018)]. The most frequent subtype being found in immunocompromised patients was ST3 [41.7% (95% CI: 31.4-52.7%)], followed by ST1 [31.7% (95% CI: 23.2-41.8%)] and ST2 [23.1% (95% CI: 14.8-34.1%)]. Also, the weighted frequency of Blastocystis in various subgroups (publication year, WHO regions, geographical distribution, continents, and country income) was analyzed separately. In total, the results of the present meta-analysis highlighted that one's immunodeficiency status is probably associated with an increased Blastocystis infection, underpinning strict preventive measures to be taken.

Abstract
Blastocystis spp. are controversial unicellular protists that inhabit the gastrointestinal tract of humans and a wide range of animals worldwide. This review provides an overview of the prevalence and distribution of Blastocystis spp. and their subtypes throughout Asia. Research articles reporting on the presence of Blastocystis spp. in locations within Asia, between 1 January 2010, and 10 May 2021, were obtained from Scopus, PubMed, and Google Scholar. In 427 articles, the prevalence of Blastocystis spp. in 31 countries within the last decade was revealed. Isolates were found in humans, various mammals, birds, reptiles, insects, water sources, vegetables, and ambient air. Prevalence of Blastocystis spp. varied widely across host categories. Subtypes identified throughout Asia were STs 1-14, and ST18-22 (novel subtypes). ST1, ST2, ST3, ST4 were the most frequently isolated in humans; ST5 in pigs; ST10 and ST14 in goats, sheep, and cattle; and ST6 and ST7 in chickens. ST1 and ST3 were most common in water samples. ST1, ST2, ST3, ST4, ST5 and ST6 were shared by humans, animals, and water sources. There is a growing interest in the study of Blastocystis spp. and their subtypes in Asia. Due to the isolation of Blastocystis spp. from biotic and abiotic sources in Asia, the application of the One Health (OH) approach to the study of Blastocystis spp. is proposed for improved perception of this organism.

Abstract
Giardia duodenalis is one of the leading causes of diarrhea, mostly in underdeveloped nations of Africa and Asia. The present review provides insights into the prevalence, odds ratios (ORs) and associated risk factors of giardiasis in HIV/AIDS patients. Four major English databases (Web of Science, PubMed, Scopus, and Google Scholar) were excavated for relevant literature without time limitation until 20 November 2020. Next, meta-analysis was performed using a random-effects model and 95% confidence intervals (CIs). As well, heterogeneity among studies was evaluated using Cochran's Q and the I2-statistic. Totally, 19,218 HIV/AIDS patients in 130 studies were examined, showing a 5% (95% CI: 4.2%-6%) pooled prevalence. Also, the weighted random-effects OR of G. duodenalis infection among HIV/AIDS patients in comparison with their controls in 48 case-control studies was estimated as 1.71% (95% CI: 1.1%-2.66%, p = 0.016). Based on sensitivity analysis, there was no remarkable variation in the pooled OR upon omitting individual studies. Diarrhea was a potent risk factor, since HIV/AIDS patients with diarrhea were 3.8-times (95% CI: 1.6-8.9, p = 0.002) more prone to G. duodenalis infection than those without diarrhea. Moreover, the prevalence of the parasitic infection was 1.2-times higher in patients without antiretroviral therapy (ART) than those with ART (p = 0.312). Meta-regression was employed to evaluate the possible association between G. duodenalis frequency in HIV/AIDS patients and some variables such as sample size, publication year, and HDI. Additionally, the pooled prevalence of G. duodenalis infection was estimated based on several subgroups, including publication years, WHO regions, countries, continents, country incomes, and CD4+ T-cell levels. Altogether, the epidemiology of giardiasis in HIV/AIDS patients and its association with various risk factors is still open to question and requires more detailed and comprehensive investigations.

Abstract
Background Intestinal parasitic infections are major public health problems throughout the world, particularly in people living with HIV/AIDS. People living with HIV/AIDS are vulnerable groups for a variety of diseases, hence they are easily affected by opportunistic and non-opportunistic intestinal parasites due to the weakening of their immunity. Therefore, this study aimed to estimate the pooled prevalence and factors associated with intestinal parasitic infections among people living with HIV/AIDS in Ethiopia. Methods Articles were identified through search engines in the online electronic databases PubMed/MEDLINE, EMBASE, HINARI, CINAHL, Cochrane Library, Google Scholar, and reference lists of previous studies following the PRISMA Protocol. Studies conducted between 2003 and 2020 with English language were included in this study. This review included papers with having high-quality NOS scores. Meta-analysis was computed using STATA version 11 software. Heterogeneity was assessed using the Cochrane Q-test and I2 test statistics. Subgroup and sensitivity analysis was employed with evidence of heterogeneity. Publication bias was determined using the funnel plot and Egger’s regression test statistic. Results This study included a total of twenty-two cross-sectional studies with 5,833 study participants. The mean age of the study participants was 35 years old. The pooled prevalence of intestinal parasitic infection among people living with HIV/AIDS in Ethiopia was 39.15% (95%CI: 32.34, 45.95). The pooled prevalence of intestinal parasitic infections among people living with HIV/AIDS who had taking ART and who had not to start ART was found to be 28.27% (95%CI 22.47, 34.06) and 41.63% (95%CI: 28.75, 54.52) respectively. Unavailability of latrine (AOR: 4.87, (95% CI: 2.39, 9.92)), CD4+ T cell count <200cells/μl ((AOR: 3.53, (95%CI: 1.98, 6.27)), and having a history of diarrhea (AOR: 4.79 (95%CI: 1.53, 14.99) were factors significantly associated with intestinal parasitic infections. Conclusion In this study, the overall pooled prevalence of intestinal parasitic infections among HIV/AIDS patients in Ethiopia was relatively high. CD4+ T-cell count <200cells/μl, unavailability of a latrine, and history of diarrhea were significantly associated with intestinal parasitic infections. Therefore, the policymakers and health care professionals could give special attention to the presence of latrines, early detection and treatment of intestinal parasitic infections, and early initiation of ART drugs.

Abstract
BACKGROUND Blastocystis is one of the most common pathogens of the human intestine, caused by an emerging parasite, which can lead to severe symptoms and even death in immunocompromised patients. We aimed to determine the global prevalence of Blastocystosis infection in people with immunodeficiency. A systematic literature search was conducted on Web of Science, Scopus, Google scholar, Science Direct and MEDLINE databases to select all observational studies reporting the prevalence of Blastocystosis infection in Worldwide, based on different diagnostic methods in immunocompromised patients of any age and published from inception to February 2019. Pooled estimates and 95% confidence intervals (95% CIs) were calculated using random effects models and in addition, the I2 statistic was calculated. The geographic distribution of studies was evaluated and the diagnosis of Blastocystis was compared by various techniques. Electronic databases were reviewed for Blastocystosis infection in HIV/AIDS, cancer and other immunocompromised patients, and meta-analyses were conducted to calculate the overall estimated prevalence. Total68 eligible studies were included. The estimated pooled prevalence rate of Blastocystosis infection in immunocompromised patients was overall 10% (95% CI, 7-13%; I2 96.04%) (P < 0.001), of whom 21% [18-25] were in Australia, 12% [4-24] in America, 11% [6-17] in Europe and 10% [5-15], 7% [3-13] in Asia and Africa, respectively. It was calculated that the estimated pooled prevalence rate of Blastocystosis infection in immunocompromised patients was overall 10% and the prevalence estimates ranged from 0.44 to 72.39. Also, overall the prevalence of parasites co-infection in immunocompromised patients was detected as 0.024%. Our finding showed that immunocompromised people show a high prevalence of Blastocystosis infection compared to the control population. Adequate information on the prevalence rate is still missing from many countries. However, current information underscore that Blastocystis should not be neglected.

Abstract
In Ethiopia, only limited data are available regarding the prevalence of enteric bacterial pathogens and enteroparasites in human immunodeficiency virus (HIV) -infected individuals with diarrhoea. Hence, this study aims to assess the prevalence of enteric bacteria and enteroparasites, and also the antibiotic susceptibility patterns of bacteria in them. An institution-based cross-sectional study was performed in HIV patients with diarrhoea, who visited the Anti-Retroviral Therapy Clinic of the Arba Minch General Hospital between 1 March and 31 August 2019. Data pertaining to sociodemographic characteristics and other factors were collected using a structured questionnaire. Stool culture is of utmost importance in the case of HIV-infected individuals with diarrhoea. Stool samples were collected and examined for bacterial and parasitic pathogens following standard procedures. The antibiotic susceptibility test was performed as per the Kirby-Bauer disc diffusion technique. Data were analysed using SPSS software. A total of 180 individuals were included in the stool collection process. The prevalence rates of enteric bacteria and enteroparasites were 8.3% and 36.1%, respectively. Parasitic infections were more frequent than bacterial infections in these HIV-infected individuals; commonly identified enteroparasites were Giardia lamblia (8.9%) and Cryptosporidium parvum (8.3%). Campylobacter sp. was the most predominant enteric bacterial isolate (4.4%), followed by Salmonella (2.1%) and Shigella (1.1%) species. CD4 counts <200 cells/μL was significantly associated with both bacterial infections (adjusted OR 9.55, 95% CI 1.54-59.3, p 0.015) and parasitic infections (adjusted OR 3.53, 95% CI 1.3-17.9, p 0.03). Multidrug resistance was also detected in 100%, 75% and 60% of Shigella, Campylobacter and Salmonella sp., respectively. We found that enteroparasitic infections were more frequent than bacterial infections. Statistical analysis revealed that CD4 T-cell counts <200 cells/μL, quality of drinking water sources, hand washing habits after toilet and the presence of domestic animals were significantly associated with the prevalence of enteric pathogens.

Cryptosporidiosis in HIV-positive patients and related risk factors: A systematic review and meta-analysis. ACTA ACUST UNITED AC 2020; 27:27. [PMID: 32351207 PMCID: PMC7191976 DOI: 10.1051/parasite/2020025] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Accepted: 04/09/2020] [Indexed: 11/28/2022]
Abstract
Cryptosporidium is one of the major causes of diarrhea in HIV-positive patients. The aim of this study is to systematically review and meta-analyze the prevalence of Cryptosporidium in these patients. PubMed, Science Direct, Google Scholar, Web of Science, Cochrane and Ovid databases were searched for relevant studies dating from the period of 1 January 2000 to 31 December 2017. Data extraction for the included studies was performed independently by two authors. The overall pooled prevalence was calculated and subgroup analysis was performed on diagnostic methods, geographical distribution and study population. Meta-regression was performed on the year of publication, proportion of patients with diarrhea, and proportion of patients with CD4 < 200 cells/mL. One hundred and sixty-one studies and 51,123 HIV-positive participants were included. The overall pooled prevalence of Cryptosporidium infection in HIV-positive patients was 11.2% (CI95%: 9.4%–13.0%). The pooled prevalence was estimated to be 10.0% (CI95%: 8.4%–11.8%) using staining methods, 13.5% (CI95%: 8.9%–19.8%) using molecular methods, and 26.3% (CI95%: 15.0%–42.0%) using antigen detection methods. The prevalence of Cryptosporidium in HIV patients was significantly associated with the country of study. Also, there were statistical differences between the diarrhea, CD4 < 200 cells/mL, and antiretroviral therapy risk factors with Cryptosporidiosis. Thus, Cryptosporidium is a common infection in HIV-positive patients, and safe water and hand-hygiene should be implemented to prevent cryptosporidiosis occurrence in these patients.

Abstract
The number of human immunodeficiency virus (HIV) cases increases annually, and Indonesia has become the country with the fastest HIV/acquired immunodeficiency syndrome (AIDS) epidemic spread among the five Southeast Asian countries. Indonesia entered the critical phase of HIV/AIDS infections after 5 out of the 33 provinces, namely, Papua, Jakarta, Bali, West Java, and East Java, reported HIV/AIDS epidemic since 2004. In AIDS pathophysiology and immune-suppression are severe, thus, opportunistic intestinal parasitic infections that cause diarrhea in HIV infection may be fatal. Several studies have suggested that Cryptosporidium parvum, Isospora belli, and Blastocystis hominis are the most common intestinal protozoan parasites categorized as AIDS associated illness. Diarrhea caused by parasites is considerably suspected in the cases of chronic and persistent diarrhea in adults, in an era of increasing HIV/AIDS cases nowadays. The present review highlights the current advances in etiologic agents of HIV/AIDS opportunistic infections among countries, epidemiology and prevalence, lifecycle, risk factors, examination methods, and treatment.

Abstract
Purpose: To determine the prevalence of Cryptosporidium by age, sex, and duration on antiretroviral therapy (ART) and establish hygienic malpractices that may predispose to infection. Methods: We enrolled 138 HIV/AIDS patients on ART from June to October 2018. Stool samples were collected from study participants, wet saline preparations made and examined, stool samples concentrated using formal ether concentration, and smears stained using the modified Ziehl–Neelsen technique. Structured questionnaires were used to collect demographic data and hygienic malpractices that predisposed study participants to cryptosporidiosis infection. Results: Of 138, 99 (71.7%) were females and 39 (28.7%) males. The age range was 9–69 years and mean age 37 years. The overall prevalence of cryptosporidiosis was three (2.17%). The most affected age-groups were 31–40 years (3.85%) and 21–30 years (3.22%), and only females (3.03%) were affected. The distribution of cryptosporidiosis according to the duration spent on ART showed that those who had spent <1 year on ART were the most affected (11.1%), followed by those who had spent 1–5 years 1 (2.2%), while those patients on ART for 6-10 years were 1 (1.7%) and those on ART for more than 10 years were not affected. There was no significant association between cryptosporidiosis and sex (P=0.272), educational background (P=0.670), handwashing (P=0.853), drinking boiled water (P=0.818), duration on ART (P=0.263), occupation (P=0.836), and age (P=0.723). Conclusion: The prevalence reported in this study is low; however, it is still vital for clinicians to proceed to have cryptosporidiosis as the main differential in HIV/AIDS patients with gastrointestinal infections.

Abstract
Enterotoxigenic Escherichia coli (ETEC)-induced diarrhea is a devastating disease and one of the third leading causes of infectious disease-associated mortalities worldwide. Despite recent advances in the identification of the association between gut microbiota and diarrhea, a lack of understanding exists on the status of gut microbiota in rats treated with ETEC. In the present study, a rat model of Escherichia (E.) coli O101-induced diarrhea was established. The diarrhea incidence and index, as well as histological changes, were assessed. In addition, Illumina MiSeq sequencing of V3-V4 hypervariable regions of 16S ribosomal RNA was employed to investigate the changes in the gut microbiota profiles in the feces of the diarrhea rats. The results indicated that E. coli O101 increased the diarrhea index and injury in the intestinal tissues, whereas it decreased the bacterial richness and shifted the distribution pattern of the bacterial communities in the phylum, order and genus levels in the fecal samples. Notably, the proportion of bacteria Prevotella, Enterococcus and Akkermansia was significantly decreased, while the pathogenic bacteria Escherichia/Shigella were significantly increased in diarrhea rats. Taken together, the gut microbiota is closely associated with E. coli O101-induced diarrhea in lower microbial diversity and dysbiosis of gut microbiota at different taxonomical levels.

Abstract
Background Most HIV clients die of AIDS related intestinal parasitic infections rather than due to the HIV infection itself. Therefore, this study was aimed at determining the prevalence of intestinal parasite and their associated factors among HIV/AIDS clients at the University of Gondar Hospital, Northwest Ethiopia. Methods Institution based cross sectional study was conducted using systematic random sampling technique from March to May 2016. A semi-structured questionnaire was used to collect data. Stool samples were collected and processed using direct wet mount, formol-ether concentration and modified Ziehl-Neelson staining techniques. Besides, blood samples were collected for CD4+ count estimation. Both descriptive and logistic regression analyses were used in data analysis. P-values <0.05 were considered as statistically significant. Results A total of 223 participants were enrolled in this study, and the prevalence of intestinal parasitosis was found to be 29.1%. The most predominant intestinal parasite detected was cyst of Entamoeba histolytica (8.5%) followed by Ascaris lumbricoides (6.7%), Strongyloides sterocoralis (3.6%) and Cryptosporidium parvum (3.1%), whereas Schistosoma mansoni (0.9%) and Hymenolepis nana (0.9%) were the least detected. Absence of toilet (AOR= 19.4, CI: 6.46–58.3), improper hand washing before meal (AOR=11.23, 95% CI: 4.16–30.27 and CD4+ count < 200 cells/mm3 (AOR=33.31, 95% CI: 9.159–121.149) had significant association with prevalence of intestinal parasites. Conclusion The study indicated that intestinal parasites are still a problem among HIV/AIDS patients in the study area. Thus, routine examination for intestinal parasites and interventions should be carried out for better management of clients.

Abstract
INTRODUCTION Enteric parasitic infections have been increasingly recognized as etiology of life-threatening chronic diarrhea in PLWHA in sub-Saharan Africa. This study investigated the prevalence and burden of intestinal parasitic infection among PLWHA in Abeokuta, southwest Nigeria. METHODS Freshly passed stool samples were collected from PLWHA. Detection of Cryptosporidium spp and Microsporidium spp was carried out with Kinyoun's stain and Weber's Chromotrope-based stain respectively. Investigation of other intestinal parasites was done using the direct saline preparation and formol-ether concentration methods. CD4+ T cell count was measured using Partec flow cytometry technique. RESULTS A total of 231 (males: females 96:135; mean age 31.81±11.40 years) PLWHA were recruited into the study, among whom 84 (36.4%) were infected with at least one intestinal parasites. Fifty two (22.5%) individuals were positive for Cryptosporidium spp and a significant association between Cryptosporidium sppand diarrhea was observed (p=0.006). Seven (3.0%) were positive for Microsporidium spp. Helminths recovered included Ascaris lumbricoides (20.8%), hookworm (6.5%), Strongyloides stercoralis (4.3%), Trichuris trichiura (5.6%) and Taenia spp. (5.6%). Cryptosporidium spp, Microsporidium spp and S. stercoralis were significantly associated with CD4+ count ≥ 200 cells/mm3 (p<0.05). Cryptosporidium sppand A. lumbricoides were significantly observed among patients that are anti-retroviral therapy (ART) naive. CONCLUSION High prevalence of opportunistic parasitic infection was significantly correlated with diarrhea, low CD4+ count and ART naïve individuals in the study. These findings re-emphasize the need for early diagnosis of opportunistic parasites and appropriate intervention among PLWHA.

Abstract
BACKGROUND Diarrhea caused by opportunistic intestinal protozoa is a common problem in HIV infection. We aimed to establish the prevalence of Cryptosporidium, misrosporidia, and Isospora in HIV-infected people using a systematic review and meta-analysis, which is central to developing public policy and clinical services. METHODS We searched PubMed, ScienceDirect, Google Scholar, Embase, Chinese Web of Knowledge, Wanfang, and Chongqing VIP databases for studies reporting Cryptosporidium, microsporidia, or Isospora infection in HIV-infected people. We extracted the numbers of people with HIV and protozoa infection, and estimated the pooled prevalence of parasite infection by a random effects model. RESULTS Our research identified 131 studies that reported Cryptosporidium, microsporidia, and Isospora infection in HIV-infected people. We estimated the pooled prevalence to be 14.0% (3283/43,218; 95% CI: 13.0-15.0%) for Cryptosporidium, 11.8% (1090/18,006; 95% CI: 10.1-13.4%) for microsporidia, and 2.5% (788/105,922; 95% CI: 2.1-2.9%) for Isospora. A low prevalence of microsporidia and Isospora infection was found in high-income countries, and a high prevalence of Cryptosporidium and Isospora infection was found in sub-Saharan Africa. We also detected a high prevalence of Cryptosporidium, microsporidia, and Isospora infection in patients with diarrhea. Sensitivity analysis showed that three studies significantly affect the prevalence of Isospora, which was adjusted to 5.0% (469/8570; 95% CI: 4.1-5.9%) by excluding these studies. CONCLUSIONS Our findings suggest that HIV-infected people have a high prevalence of Cryptosporidium, microsporidia, and Isospora infection in low-income countries and patients with diarrhea, especially in sub-Saharan Africa, reinforcing the importance of routine surveillance for opportunistic intestinal protozoa in HIV-infected people.

Abstract
PURPOSE OF REVIEW The review examines the changing causes and the investigation of infectious and noninfectious diarrhoea in individuals with HIV. RECENT FINDINGS Despite the excellent prognosis conferred by combination antiretroviral therapy, diarrhoea is still common in HIV-positive individuals and is associated with reduced quality of life and survival. There is increasing interest in the importance of Th17 and Th22 T cells in the maintenance of mucosal immunity within the gut, and in the role of the gut microbiome in gut homeostasis. Bacterial causes of HIV-associated diarrhoea continue to be important in resource-poor settings. In other settings, sexually transmitted enteric infections such as lymphogranuloma venereum and shigellosis are increasingly reported in men who have sex with men. HIV increases the risk of such infections and the presence of antimicrobial resistance. Parasitic causes of diarrhoea are more common in individuals with uncontrolled HIV and low CD4 counts. Noninfectious causes of diarrhoea include all classes of antiretroviral therapy, which is under-recognised as a cause of poor treatment adherence. Pancreatic dysfunction is remediable and the diagnostic workup of HIV-related diarrhoea should include faecal elastase measurements. New antimotility agents such as crofelemer may be useful in managing secretory diarrhoea symptoms. SUMMARY Clinicians looking after patients with HIV should ask about diarrhoeal symptoms, which are under-reported and may have a remediable infectious or noninfectious cause.
