Bacterial contamination of mobile phones of health professionals in Eastern Ethiopia: antimicrobial susceptibility and associated factors

BACKGROUND

Mobile phones of health care professionals could harbor microbes which cause nosocomial infections to the patient, family members, and the community at large. Thus, the aim of this study was to determine the prevalence of bacterial contamination of the mobile phones of health professionals, identify bacterial isolates, assess their antimicrobial susceptibility patterns, and define the associated factors.

METHOD

A cross-sectional study was conducted from February to March 2018 on 226 health professionals' mobile phones which were selected by a simple random sampling technique. Data were collected using a self-administered questionnaire. A swab sample from each of health professional's mobile phone device was collected and transported to the microbiology laboratory for bacterial culture and antimicrobial susceptibility tests. Data were entered into EpiData version 3.1 and analyzed by using the Statistical Package for Social Sciences (SPSS) program version 20.

RESULT

The overall prevalence of mobile phone contamination with one or more bacteria was 94.2%. Coagulase-negative staphylococci (CoNS; 58.8%), Staphylococcus aureus (14.4%), and Klebsiella species (6.9%) were the most predominant bacterial isolates. The overall prevalence of multidrug-resistant bacteria was 69.9%. About half of Gram-positive and Gram-negative bacteria were resistant to ampicillin and trimethoprim-sulfamethoxazole. Male sex (adjusted odds ratio (AOR) 4.1, 95% confidence interval (CI) 1.1, 15.8) and the absence of regular phone cleaning/disinfecting were found to be the most significant factors (AOR 4.1, 95% CI 1.2, 13.5) associated with health care professionals' mobile phone bacterial contamination.

CONCLUSION

There is a high contamination rate of mobile phones with nosocomial pathogens. Most of the isolates were resistant to ampicillin and trimethoprim-sulfamethoxazole and also multidrug-resistant. A mobile phone belonging to male health professionals and to those not disinfecting mobile phones was significantly contaminated with bacteria. Therefore, strategies for preventing nosocomial transmission of drug-resistant pathogens through mobile phones, like hand washing and cleaning mobile phones, are recommended.

Prevalence and incidence of carbapenem-resistant K. pneumoniae colonization: systematic review and meta-analysis

BACKGROUND

Klebsiella pneumoniae is a gram-negative rod belonging to the order Enterobacterales and having a wide distribution in the environment, including the human colon. Recently, the bacterium is one of the known problems in the healthcare setting as it has become resistant to last-resort drugs like carbapenems. The colonized person can serve as a reservoir for his/herself and others, especially in the healthcare setting leading to nosocomial and opportunistic infections. Therefore, we aimed to quantitatively estimate the rate of prevalence and incidence of colonization with carbapenem-resistant K. pneumoniae.

METHODS

A literature search was conducted on PubMed/MEDLINE, Google Scholar, Science Direct, Cochrane Library, WHO Index Medicus, and university databases. The study includes all published and unpublished papers that addressed the prevalence or incidence of K. pneumoniae colonization. Data were extracted onto format in Microsoft Excel and pooled estimates with a 95% confidence interval calculated using Der-Simonian-Laird random-effects model. With the use of I² statistics and prediction intervals, the level of heterogeneity was displayed. Egger's tests and funnel plots of standard error were used to demonstrate the publication bias.

RESULTS

A total of 35 studies were included in the review and 32 records with 37,661 patients for assessment of prevalence, while ten studies with 3643 patients for incidence of colonization. The prevalence of carbapenem-resistant K. pneumoniae colonization varies by location and ranges from 0.13 to 22%, with a pooled prevalence of 5.43%. (3.73-7.42). Whereas the incidence of colonization ranges from 2 to 73% with a pooled incidence of 22.3% (CI 12.74-31.87), both prevalence and incidence reports are majorly from developed countries. There was a variation in the distribution of carbapenem resistance genes among colonizing isolates with KPC as a prominent gene reported from many studies and NDM being reported mainly by studies from Asian countries. A univariate meta-regression analysis indicated continent, patient type, study design, and admission ward do not affect the heterogeneity (p value>0.05).

CONCLUSION

The review revealed that colonization with K. pneumoniae is higher in a healthcare setting with variable distribution in different localities, and resistance genes for carbapenem drugs also have unstable distribution in different geographic areas.

Bacterial otitis media in sub-Saharan Africa: a systematic review and meta-analysis

BACKGROUND

Otitis media is inflammation of the middle ear, comprising a spectrum of diseases. It is the commonest episode of infection in children, which often occurs after an acute upper respiratory tract infection. Otitis media is ranked as the second most important cause of hearing loss and the fifth global burden of disease with a higher incidence in developing worlds like Sub-Saharan Africa and South Asia. Therefore, this systematic review is aimed to quantitatively estimate the current status of bacterial otitis media, bacterial etiology and their susceptibility profile in sub-Saharan Africa.

METHODS

A literature search was conducted from major databases and indexing services including EMBASE (Ovid interface), PubMed/MEDLINE, Google Scholar, ScienceDirect, Cochrane Library, WHO African Index-Medicus and others. All studies (published and unpublished) addressing the prevalence of otitis media and clinical isolates conducted in sub-Saharan Africa were included. Format prepared in Microsoft Excel was used to extract the data and data was exported to Stata version 15 software for the analyses. Der-Simonian-Laird random-effects model at a 95% confidence level was used for pooled estimation of outcomes. The degree of heterogeneity was presented with I2 statistics. Publication bias was presented with funnel plots of standard error supplemented by Begg's and Egger's tests. The study protocol is registered on PROSPERO with reference number ID: CRD42018102485 and the published methodology is available from http://www.crd.york.ac.uk/CRD42018102485.

RESULTS

A total of 33 studies with 6034 patients were included in this study. All studies have collected ear swab/discharge samples for bacterial isolation. The pooled isolation rate of bacterial agents from the CSOM subgroup was 98%, patients with otitis media subgroup 87% and pediatric otitis media 86%. A univariate meta-regression analysis indicated the type of otitis media was a possible source of heterogeneity (p-value = 0.001). The commonest isolates were P. aeruginosa (23-25%), S. aureus (18-27%), Proteus species (11-19%) and Klebsiella species. High level of resistance was observed against Ampicillin, Amoxicillin-clavulanate, Cotrimoxazole, Amoxicillin, and Cefuroxime.

CONCLUSION

The analysis revealed that bacterial pathogens like P. aeruginosa and S. aureus are majorly responsible for otitis media in sub-Saharan Africa. The isolates have a high level of resistance to commonly used drugs for the management of otitis media.

Predictors of self-care activities of outpatient diabetic residents in Harar and Dire Dawa: A hospital-based cross-sectional study

OBJECTIVES

Diabetes mellitus is a metabolic disorder of major public health importance due to its prevalence and potential health complication. The success of long-term maintenance therapy of diabetes patients depends largely on their ability to adherence to self-care practices. Africa's most populous country, Ethiopia, has the highest burden of diabetes mellitus. However, studies on self-care activities of diabetic patients are limited. Therefore, this study measures the level of self-care activities of diabetic patients in a follow-up clinic of public hospitals in Harar and Dire Dawa, Eastern Ethiopia.

METHODS

A hospital-based cross-sectional study was conducted on 320 randomly selected diabetic patients in Harar and Dire Dawa. A standard diabetic self-care activity interview tool was used to collect the data. Data were entered into Epi-data v 3.1 and STATA v 14.2 was used for analysis. Our outcome variable, self-care activities, has three ordered categories and a robust Ordinal logistic regression was used to identify predictors. All statistical tests with p-value <0.05 were considered as statistically significant.

RESULTS

The self-care activities of study participants were rated good for 38.1% (95% confidence interval: 32.94, 43.60). Being rural residents (adjusted odds ratio = 0.38, 95% confidence interval: 0.17, 0.82), attended secondary education (adjusted odds ratio = 2.96, 95% confidence interval: 1.51, 5.78), uncontrolled blood glucose (adjusted odds ratio = 1.68, 95% confidence interval: 1.02, 2.79), and had diabetic complications (one, adjusted odds ratio = 1.91, 95% confidence interval: 1.08, 3.38; two or more, adjusted odds ratio = 4.71, 95% confidence interval: 1.81, 12.25) were significantly associated with the better diabetes mellitus self-care activities.

CONCLUSION

Significant number of diabetes mellitus patients living in rural areas did not adhere to diabetic self-care activities. This is more evident among participants who have limited or no formal education and patients with controlled blood glucose level. Therefore, individualized diabetic lifestyle education programs in follow-up clinics should target these population groups to improve self-care.

Red Blood Cell Parameters and Their Correlation with Glycemic Control Among Type 2 Diabetic Adult Patients in Eastern Ethiopia: A Comparative Cross-Sectional Study

Background

Diabetes has been proposed to inflict an insult on the hematopoietic milieu marked by changes in hematological indices including red blood cell parameters. Thus, this study aimed to assess the red blood cell parameters and their correlation with glycemic control in type 2 diabetic adult patients in comparison with apparently healthy individuals.

Methods

A comparative cross-sectional study was conducted at the chronic illness clinic of Hiwot Fana Comprehensive Specialized University Hospital from May 20 to July 10, 2022. A total of 220 (110 type 2 diabetic patients and 110 controls) study participants were selected by a simple random sampling technique. Five milliliters of venous blood were collected by the vacutainer blood collection technique. Red blood cell parameters and blood glucose levels were determined using UniCel DxH 800 and Biosystems A25 analyzers, respectively. Independent sample t-test and Pearson correlation test were used for the data analysis. P-value <0.05 was considered statistically significant.

Results

Statistically significant difference was observed in RBC parameters of T2DM patients and the control group. The mean RBC count, Hgb, Hct (P < 0.001), and MCHC (P = 0.002) in patients with type 2 diabetes was significantly lower than in the control group. However, the mean of RDW was significantly increased in type 2 diabetic patient groups than in the control group (P < 0.001). The mean RBC count, Hct, and Hgb in patients with good glycemic control were significantly higher than the patients with poor glycemic control. Besides, a statistically significant negative correlation was observed between glycemic control and RBC count, Hgb, and Hct level in diabetic patients.

Conclusion

In this study, a statistically significant difference was observed in red blood cell parameters of type 2 diabetic patients compared to the control group. A significant negative correlation was noted between glycemic control and RBC parameters in type 2 diabetic patients. Therefore, evaluation of RBC parameters should be considered for better management of patients with type 2 diabetes mellitus.

Magnitude and causes of first-line antiretroviral therapy regimen changes among HIV patients in Ethiopia: a systematic review and meta-analysis

Background

Antiretroviral therapy (ART) has markedly decreased the morbidity and mortality due to HIV/AIDS. ART regimen change is a major challenge for the sustainability of human immunodeficiency virus (HIV) treatment program. This is found to be a major concern among HIV/AIDS patients in a resource-limited setting, where treatment options are limited.

Objectives

The aim of this review is to generate the best available evidence regarding the magnitude of first-line antiretroviral therapy regimen change and the causes for regimen change among HIV patients on ART in Ethiopia.

Methods

The reviewed studies were accessed through electronic web-based search strategy from PubMed Medline, EMBASE, Hinari, Springer link and Google Scholar. Data were extracted using Microsoft Excel and exported to Stata software version 13 for analyses. The overall pooled estimation of outcomes was calculated using a random-effect model of DerSimonian–Laird method at 95% confidence level. Heterogeneity of studies was determined using I² statistics. For the magnitude of regimen change, the presence of publication bias was evaluated using the Begg’s and Egger’s tests. The protocol of this systematic review and meta-analysis was registered in the Prospero database with reference number ID: CRD42018099742. The published methodology is available from: https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=99742.

Results

A total of 22 studies published between the years 2012 and 2018 were included. Out of 22 articles, 14 articles reported the magnitude of regimen change and consisted of 13,668 HIV patients. The estimated national pooled magnitude of regimen change was 37% (95% CI: 34, 44%; Range: 15.1–63.8%) with degree of heterogeneity (I²), 98.7%; p-value < 0.001. Seventeen articles were used to identify the causes for first-line antiretroviral therapy regimen change. The major causes identified were toxicity, 58% (95% CI: 46, 69%; Range: 14.4–88.5%); TB co-morbidity, 12% (95% CI: 8, 16%; Range: 0.8–31.7%); treatment failure, 7% (95% CI: 5, 9%; Range: 0.4–24.4%); and pregnancy, 5% (95% CI: 4, 7%; Range: 0.6–11.9%).

Conclusions

The original first-line regimen was changed in one-third of HIV patients on ART in Ethiopia. Toxicity of the drugs, TB co-morbidity, treatment failure, and pregnancy were the main causes for the change of the first-line regimen among HIV patients on antiretroviral therapy.

Bacterial uropathogens and susceptibility testing among patients diagnosed with urinary tract infections at Hiwot Fana Specialized University Hospital, Eastern Ethiopia

Background:

Urinary tract infection is a common infection posing a significant healthcare burden globally. Currently, it is becoming hard to manage due to the drug resistance of uropathogens. This study aimed to evaluate the rate of culture positivity and the susceptibility pattern of isolates among clinically diagnosed patients with urinary tract infection.

Methods:

An institution-based cross-sectional study was conducted on patients clinically diagnosed with urinary tract infections and received a drug prescription at Hiwot Fana Specialized University Hospital from August 2018 to June 2019. A clean-catch mid-stream urine specimen was collected and bacterial identification and susceptibility test were performed using standard microbiological methods. Data were entered into EpiInfo 7 and exported to STATA 15 for analysis. Data were analyzed using descriptive analysis and bi-variate and multivariate regression analyses and presented with graphs, frequency, and tables.

Results:

A total of 687 urine samples were collected from patients with clinically diagnosed urinary tract infections. The mean age was 31 years and 56.62% were female. 28.38% of the participants had a culture-positive result, of which 86.15% had monomicrobial infections. Inpatients (AOR = 3.8, 95% CI = (1.8–7.9)) and hypertensive patients (AOR = 2.1, 95% CI = (1.1–4.4)) had higher odds of culture-positive results. Staphylococcus species (35.3%), E. coli (25.34%), Pseudomonas species (6.8%), and other Enterobacterales are isolated. Most isolates showed resistance to more than one drug, and amikacin, gentamicin, and nitrofurantoin showed relatively higher activity against isolates.

Conclusion:

About one-third of the clinically diagnosed patients with urinary tract infection were culture-positive with many types of bacterial uropathogens. Inpatients and hypertensive patients had a higher risk of developing bacterial infections. Bacterial isolates showed different percentages of susceptibility to the tested antibiotics.

Bacterial profile, their antibiotic susceptibility pattern, and associated factors of urinary tract infections in children at Hiwot Fana Specialized University Hospital, Eastern Ethiopia

BACKGROUND

Urinary tract infections (UTIs) are common pediatric infections and contribute to high morbidity and mortality. At present, the antimicrobial resistance emergency has quadrupled worldwide and poses a serious threat to the treatment of patients. However, there have been few studies on UTIs in children in Ethiopia, particularly in the east.

OBJECTIVE

This study aimed to assess the bacterial profile of urinary tract infections, their susceptibility to antimicrobial agents, and associated factors in under-five children at Hiwot Fana Specialized University Hospital, eastern Ethiopia.

METHOD

We conducted hospital-based quantitative study on 332 consecutively selected under-five children from March 20 to June 10, 2021. Parents and guardians were interviewed to collect data using a structured questionnaire. Random urine samples were collected aseptically, and standard microbiological techniques were used to identify the bacteria and test for susceptibility to various antibiotics. Data were entered into Epi Info version 7 and exported to Statistical Package for the Social Sciences (SPSS) version 25 for analysis. Data were analyzed using descriptive analysis, bivariate, and multivariable logistic regression analysis. The crude odds ratio (COR) and adjusted odds ratio (AOR) with their respective 95% confidence intervals (CI) were used to determine the significance of the predictors. A p-value at a 95% confidence interval of less than 0.05 was considered statistically significant.

RESULTS

The overall prevalence of bacterial urinary tract infections was 80 (24.1%) 95% CI:19.40-29.00%). Most of the bacterial isolates 55 (68.75%) were gram-negative bacteria, predominantly E. coli 23 (28.75%) and K. pneumoniae 10 (12.50%). Being a rural resident (AOR: 4.10, 95%CI: 1.45 11.54), uncircumcised male (AOR: 3.52, 95%CI: 1.33, 9.39), previous history of antibiotic usage (AOR: 7.32, 95%CI: 2.11, 25.37), indwelling catheterization (AOR: 10.35, 95%CI: 3.74, 28.63), previous history of urinary tract infections (AOR: 5.64, 95% CI: 1.36, 23.38), and urinary frequency (AOR: 5.56, 95%CI: 2.03, 15.25) had higher odds of culture positive result. The majority of the isolates have shown high levels of antibiotic resistance. Meropenem, ciprofloxacin, and amoxicillin-clavulanic acid were effective against gram-negative uropathogens, whereas rifampin and ciprofloxacin were the most sensitive drugs for gram-positive isolates. From the tested bacterial isolates, 53/86 (61.6%), 11/86 (11.6%), and 2/86 (2.3%) were found to have multidrug resistance (MDR), extreme drug resistance (XDR), and pan drug resistance (PDR), respectively.

CONCLUSIONS

About one-fourth of the children were culture-positive for many types of bacterial uropathogens; this is higher compared with most of the previous studies in Africa. Rural dwellers, uncircumcised males, indwelling catheterization, a history of antibiotic use and urinary tract infection, and frequent urination all had a higher risk of bacterial infections. Many isolates were resistant to multiple drugs, primarily beta-lactams. Urinary tract infections as well as the growth and spread of resistant bacterial pathogens should be monitor regularly.

Predictors of surgical site infection among women following cesarean delivery in eastern ethiopia. prospective cohort study

Despite the availability of prophylactic antibiotics prior to skin incisions, surgical site infection (SSI) following cesarean section (CS) remains an unresolved health issue. As a result, this study aimed to assess the incidence and predictors of SSI after a CS.

Methods

The authors conducted a prospective cohort study in eastern Ethiopia. The women were serially enrolled until the desired sample size was reached. A structured questionnaire was used to collect data. Women were followed at the hospital during their weekly visits. Culture-based microbiological methods were used to identify causal agents. A binary logistic regression model was used to identify the predictors of SSI after CS.

Results

Among serially enrolled women, 336 were followed for 30 days. The incidence of SSI was 7.74% (95% CI: 7.68-7.80). Rupture of the membrane before operation [adjusted odds ratio (AOR)=3.75, 95% CI: 1.85-16.6], labor duration greater than 24 h (AOR=4.04, 95% CI: 1.52-10.79), and postoperative hemoglobin less than 11 g/dl (AOR=3.42, 95% CI: 1.32-8.87) were all significantly associated with SSI. The most common isolated pathogen was Staphylococcus aureus, followed by Escherichia coli.

Conclusions

Nearly one-tenth of the women developed SSIs. Factors such as rupture of the membrane before the operation, absence of antenatal care, labor duration greater than 24 h, a midline skin incision, and postoperative hemoglobin less than 11 g/dl were the predictors of SSI. To reduce the incidence of SSI, policymakers should consider the importance of high-quality antenatal care, shorten the duration of labor, and maintain women's hemodynamics in future SSI prevention bundles.

Hepatitis B virus infection and associated risk factors among medical students in eastern Ethiopia

BACKGROUND

Hepatitis B virus (HBV) is a highly contagious pathogen that has become a severe public health problem and a major cause of morbidity and mortality, particularly in developing countries. Medical students are at high occupational risk during their training. However, no facility-based studies were found among medical students in eastern Ethiopia. Thus, this study aimed to investigate the seroprevalence of Hepatitis B Virus and associated factors among medical students in eastern Ethiopia.

METHODS

A facility-based cross-sectional study was conducted among 407 randomly selected medical students from March to June 2018. A pretested and structured questionnaire was used to collect data on socio-demographic characteristics and other risk factors. A 5ml blood was collected, and the serum was analyzed for Hepatitis B surface antigen (HBsAg) using the Instant Hepatitis B surface antigen kit. Data were entered using Epidata version 3.1 and analyzed using SPSS statistical packages version 22. Outcome and explanatory variables were described using descriptive summary measures. Binary and multivariable logistic regression was conducted at 95% CI and an association at P-value < 0.05 was declared statistically significant.

RESULTS

The seroprevalence of hepatitis B virus surface antigen was 11.5% (95%CI = 8.6, 14.7). Poor knowledge of universal precaution guideline (AOR = 2.58; 95% CI = [1.35-4.93]), history of needle stick injury (AOR = 2.11; 95% CI = [1.07-4.18]) and never been vaccinated for HBV (AOR = 2.34; 95% CI = [1.17-4.69]) were found statistically significantly associated with HBsAg positivity after multivariate analysis.

CONCLUSION

Hepatitis B virus infection rate is high among health care trainees in eastern Ethiopia. Improvement at health care practice centers safety through training on universal precaution guidelines, and scaling up HBV vaccination is mandatory.

Trend Analysis And Seasonality Of Tuberculosis Among Patients At The Hiwot Fana Specialized University Hospital, Eastern Ethiopia: A Retrospective Study

Purpose

Tuberculosis (TB) is one of the top 10 leading killer diseases in developing countries, particularly in Sub-Saharan Africa, including Ethiopia. Thus, this study aimed to assess the trend analysis and seasonality of TB at Hiwot Fana Specialized University Hospital, Eastern Ethiopia.

Methods and patients

A hospital-based retrospective study was conducted on 8,001 patients by reviewing all available patients’ data from January 1, 2015 to April 30, 2019, at the Hiwot Fana Specialized University Hospital, Eastern Ethiopia. Socio-demographic characteristics and results of the GeneXpert assay were taken from the registration book. The data were entered into EpiData 3.1 and analyzed by using the statistical Package for Social Sciences (SPSS) version 20.

Results

From a total of 8,001 samples tested using Genexpert, the overall prevalence of Mycobacterium tuberculosis and rifampicin resistance was found to be 1,254 (15.7%) and 53 (4.1%), respectively. A decreasing trend of TB prevalence was observed, and decreased from 19.3% in 2015, 18.6% in 2016, to 18.4% in 2017, 13.5% in 2018 and down to 13.0% in 2019 (P-value<0.001). The maximum number of TB cases were reported during autumn (454, 17.1%) and summer (310, 17.2%) compared to other seasons of all the study period. Being between the ages of 15–29 years (adjusted odds ratio (AOR)=1.7, 95% confidence interval (CI)=1.41–1.98), of male gender (AOR=0.84, 95% CI=0.75–0.96), experiencing a relapse of TB (AOR=0.51, 95% CI=0.35–0.78), and being HIV positive (AOR=0.51, 95% CI=0.3–0.86) were found to be factors associated with high proportion of tuberculosis.

Conclusion

Prevalence of TB has decreased year to year between January 2015 and April 2019. However, a high percentage of patients are still testing positive for TB with different seasonal variations. Thus, understanding and managing TB in seasonal variation, controlling relapse of TB, and screening of all HIV positive patients are recommended steps to reduce the transmission of tuberculosis in Ethiopia.

Hospital-Level Antibacterial Prescribing and Its Completeness in Ethiopia: Did It Adhere to Good Prescribing Practice?

Background

Antibacterial agents are an integral part of chemotherapy and play a critical role in the prophylaxis and treatment of bacterial infections. However, prescribing errors such as incomplete prescriptions that do not adhere to good prescribing practice have become a contemporary concern in hospitals in resource-limited settings. Therefore, this study aimed to assess antibacterial prescribing and its completeness among prescriptions dispensed at four governmental hospitals in Eastern Ethiopia.

Methods

A cross-sectional study was employed to assess a total of 1308 prescription encounters containing at least one antibacterial agent obtained with simple random sampling from annual antibacterial-containing prescription data of four hospitals. The data were collected retrospectively using a structured checklist.

Results

A total of 2,855 drugs were prescribed from 1308 prescribing encounters with 1496 (52.39%) being antibacterial agents. The name, age, sex, and diagnosis of the patients were written in 1158 (88.3%), 815 (62.31%), 796 (60.58%), and 183 (13.99%) prescriptions, respectively. Besides, the route of administration, strength, duration, quantity, dose, and dosage form of the drug were recorded in 2322 (81.33%), 2118 (74.19%), 1516 (53.10%), 1525 (53.42%), 746 (26.13%) and 563 (19.72%) prescriptions, respectively. Nearly 50% of the prescribing encounters were documented without a prescriber name. Dispenser name and signature were also obtained in less than 10% of the prescriptions. Combining the data of all hospitals, amoxicillin, ceftriaxone, and ciprofloxacin were identified as the top three prescribed antibacterial drugs, whereas diclofenac, paracetamol, and tramadol were the most frequently co-indicated drugs. Regarding the pharmacologic class of antibiotics, penicillins were the most commonly prescribed antibiotics (n = 596, 39.77%) followed by cephalosporins (n = 318, 21.26%) and fluoroquinolones (n=285, 19.05%).

Conclusion

Incomplete information about patient-related factors and major diagnosis, medication regimens, prescribers and dispensers was identified as a potential prescribing error and did not adhere to good prescribing practice. This can be considered as one part of the inappropriate use of antibacterial agents, a driving force for the emergence of antimicrobial resistance. This problem requires immediate and sustained action from the management of the hospitals to ensure the accountability of health professionals involved in the medication use process and to establish antimicrobial stewardship programs in such resource-limited settings.

Prevalence of Respiratory Syncytial Virus Among Children Under 5 Years of Age in Sub-Saharan Africa

Background. Pneumonia and bronchiolitis are common childhood illnesses caused by the respiratory syncytial virus. A systematic analysis of published epidemiological data in sub-Saharan African children under the age of 5 was conducted. Methods. To retrieve literature, electronic databases, indexing services, and directories such as PubMed/MEDLINE, Scopus, EMBASE (Elsevier), Google Scholar, and Worldcat were utilized. Data from the included studies were extracted after screening and eligibility evaluation. Results. The pooled prevalence rate of respiratory syncytial virus was 21% (95% CI: 17, 25). Subgroup analysis based on participants' ages showed that, prevalence was highest in children <6 months (32%). High prevalence was also found in children who were hospitalized (27%), children co-infected with HIV (28%), and children co-infected with bacteria respiratory pathogens (22%). Conclusion. The prevalence of respiratory syncytial virus infection was high in children in sub-Saharan African countries. Therefore, it should be prioritized as a major health problem.

Relationship between vaginal and gut microbiome and pregnancy outcomes in eastern Ethiopia: a protocol for a longitudinal maternal-infant cohort study (the EthiOMICS study)

INTRODUCTION

Although evidence exists on the impact of microbiota on pregnancy outcomes in many high-resource settings, there is a lack of research in many low-resource settings like Ethiopia. This study aims to fill this gap by studying the gut and vaginal microbiota changes throughout pregnancy and assess how these changes relate to pregnancy outcomes among a cohort of pregnant women in eastern Ethiopia.

METHODS AND ANALYSIS

Vaginal and stool samples will be collected using DNA/RNA Shield Collection kits three times starting at 12-22 weeks, 28-36 weeks and at birth (within 7 days). Postnatally, newborns' skin swabs (at birth) and rectal swabs will be obtained until 2 years of age. Moreover, breast milk samples at birth and 6 months and environmental samples (water, indoor air and soil) will be collected at enrolment, birth, 6, 12 and 24 months post partum. DNA will be extracted using Roche kits. Metagenomic sequencing will be performed to identify metataxonomic profiling and assess variations in microbial profiles, and α and β diversity of the microbiota.

Nasal carriage rate, associated factors, and antimicrobial susceptibility patterns of methicillin resistance Staphylococcus aureus among pre-clinical undergraduate students at the College of Health and Medical Sciences, Haramaya University, Ethiopia

Background

Staphylococcus aureus nasal carriage has been linked to higher rates of infection and morbidity. People with Methicillin-resistant Staphylococcus aureus can be a potential source of infection for others. University students living together in crowded conditions increase their risk of acquiring infections. The prevalence of S. aureus, particularly Methicillin-resistant Staphylococcus aureus nasal carriage, in Ethiopian university students is sparse.

Objective

This study aimed to determine the nasal carriage rate, associated factors, and antimicrobial susceptibility patterns of methicillin-resistant Staphylococcus aureus among pre-clinical students at the College of Health and Medical Sciences, Haramaya University, Ethiopia, from 1 July to 30 August 2022.

Methods

An institutional-based cross-sectional study was conducted among 270 randomly selected pre-clinical Health and Medical Sciences students. Data on associated factors were collected using pre-tested, structured questionnaires. A nasal swab was taken from each participant and sent to the microbiology laboratory via Amies transport media in a cold chain. There, it was cultivated using conventional techniques. The isolated colonies were found to be S. aureus, and its antimicrobial susceptibility was performed using the Kirby-Bauer disk diffusion method on Muller-Hinton agar. Methicillin-resistant Staphylococcus aureus expressing using cefoxitin based on CLSI breakpoint. Data were entered into Epi-Data version 4.4.2.1 and exported to the Statistical Package for Social Sciences (SPSS) software version 25 for analysis. Pearson's chi-square test was performed to predict the associations between variables. A p-value less than 0.05 was regarded as statistically significant.

Result

Methicillin-resistant Staphylococcus aureus nasal carriage was 5.9% (95% CI: 3.09-8.7) of cases of S. aureus nasal colonization, which was found to be 12.96% (95% CI: 8.85-16.96). Methicillin-resistant Staphylococcus aureus nasal colonization was significantly associated with the history of cigarette smoking (p = 0.000), intake of khat (p = 0.042), nose-picking habit (p = 0.003), history of sharing personal goods (p = 0.021), and history of hospitalizations (p = 0.00). All of the Methicillin-resistant Staphylococcus aureus isolates were resistant to ampicillin and cefoxitin.

Conclusion

Based on the findings, a considerable proportion of healthy students harbored Methicillin-resistant Staphylococcus aureus strains associated with behavioral factors. Furthermore, these isolates showed high resistance to cefoxitin and ampicillin. Hence, it is crucial to regularly test pre-clinical students to prevent endogenous infections and the spread of Methicillin-resistant Staphylococcus aureus.

The appropriateness of ceftriaxone utilization in government hospitals of Eastern Ethiopia: A retrospective evaluation of clinical practice

Introduction:

Drug use evaluation is a method of obtaining information to identify problems related to drug use and if properly developed, a means of correcting the problems. Ceftriaxone is among the most commonly utilized cephalosporins. Owing to a broad spectrum of activity and being used empirically, ceftriaxone has been used inappropriately posing a risk for development of antimicrobial resistance. This study is, therefore, designed to evaluate the appropriateness of ceftriaxone utilization in government hospitals in Harar town.

Methods:

A retrospective cross-sectional study was conducted in four government hospitals of Harar town by reviewing the medical records of 271 patients who received ceftriaxone from 1 January to 31 December 2016. Systematic random sampling was utilized to capture the medical records. Data were entered and analyzed using SPSS version 22.

Results:

From the 271 medical records reviewed majority of patients were from surgical ward (n = 85, 31.4%) followed by gynecology and obstetrics ward (n = 67, 24.7%). Demographically, the majority of the patients were female (n = 142, 52.4%). Patients in the age group of 20–29 years were dominant (n = 98, 36.2%). A total of 71 drugs were co-administered with ceftriaxone, the most common being metronidazole followed by tramadol. Among the co-administered drugs, unfractionated heparin (n = 6), warfarin (n = 5), and enoxaparin (n = 1) were found to have a moderate drug interaction with ceftriaxone. Ceftriaxone was commonly used for post-operative prophylaxis (n = 80, 27.5%) followed by for the management of pneumonia (n = 62, 21.3%). The result of ceftriaxone use evaluation showed that majority (n = 190, 70.1%) were found to be inappropriate. The inappropriate utilization was primarily due to wrong indication (indications for which ceftriaxone was not the primary option) (n = 114, 60.0%) followed by wrong duration (n = 54, 28.4%).

Conclusion:

Ceftriaxone was used inappropriately in more than two-thirds of the patients, with wrong indication and wrong duration contributing the majority. Inappropriate use of antibiotics may potentially lead to the emergence and spread of drug-resistant microorganisms and also ultimately exposes the patient to treatment failure, prolonged hospital stay, and higher cost of therapy.

Global Prevalence of Anemia Among Type 2 Diabetic Adult Patients: A Systematic Review and Meta-Analysis

Background

Anemia is a common and often overlooked hematological change observed in patients with diabetes mellitus. However, there is no global survey or health registry that estimates the pooled prevalence of anemia in patients with type 2 diabetes. Therefore, this study aimed to determine the global pooled prevalence of anemia among adult patients with type 2 diabetes.

Methods

This study was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. The study protocol was registered on PROSPERO with the reference number (CRD42022327135), and the link provided (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022327135) display the published methodology. Previously published articles were searched in PubMed/Medline, Cochrane Library, WHO Global Index Medicus, African Journals Online, ScienceDirect, Google Scholar, and Google from October 26 to November 09, 2022. The quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal tool. Random-effects model was used to estimate the pooled prevalence of anemia. The degree of heterogeneity among the included studies was assessed using I2 statistics. Publication bias was detected using funnel plot symmetry analysis supplemented by Egger's and Begg's tests.

Results

Twenty-four studies with a total number of 19,118 participants were included in this systematic review and meta-analysis. The overall pooled prevalence of anemia among type 2 diabetic adult patients was 27.0% (95% CI: 24.0, 31.0, I2 = 96.45%; P< 0.001). Geographical and time-based subgroup analysis showed that higher prevalence of anemia was observed in Africa region 28.0% (95% CI: 17.0, 39.0) and from 2015 to 2022, 28.0% (95% CI: 24.0, 33.0), respectively.

Conclusion

Anemia is a moderate public health problem among adult patients with type 2 diabetes. Nearly one in four patients with type 2 diabetes develops anemia. Therefore, considering the negative impact of anemia, it is important to include anemia screening in the routine assessment of diabetes-related complications.

Amoxicillin Utilization Pattern at Governmental Hospitals in Eastern Ethiopia

INTRODUCTION

Penicillin is among the highly used antibiotics in most parts of the world, with amoxicillin being the most frequently utilized drug in the category. However, amoxicillin use has been found to deviate from standard treatment guidelines (STGs).

OBJECTIVE

This study aimed to evaluate amoxicillin utilization patterns based on Ethiopian STGs criteria at four governmental hospitals in Harar town: Hiwot Fana Specialized University Hospital, Jugel Hospital, South East Command III Hospital, and Federal Harar Police Hospital in Eastern Ethiopia in 2016.

METHODS

A hospital-based retrospective cross-sectional study was employed using medication records of patients who received amoxicillin in 2016 at four governmental hospitals from May 15 to June 30, 2018. A total of 502 medication records were proportionally allocated based on the ratio of consumption data of each hospital. Simple random sampling was employed to collect the required sample from the sampling frame. The collected data were entered into SPSS version 21 and analyzed using descriptive analysis.

RESULTS

Amoxicillin was used in all age groups, including pregnant and lactating women. The majority (96.2%) of patients were from the outpatient departments. Complete blood count was the most laboratory investigation carried out in 24.9% whereas microbiological culture was not recorded at all. Top three indications include nonspecific upper respiratory tract infections (15.1%), pneumonia (13.5%) and dental problems (10.6%). Non-steroidal anti-inflammatory drugs (56.2%) were frequently co-administered agents. An appropriate utilization was made considering indication, dose, frequency and therapy duration in 23.9% as per the Ethiopian STG. The wrong indication (65.4%) was the prime reason for inappropriateness, followed by dose (14.6%) and duration of therapy (12.2%).

CONCLUSION

Amoxicillin utilization was appropriate in less than a quarter of patients. The wrong indication was the main reason for inappropriateness, predisposing to resistance development. Further studies identifying factors related to misuse and sensitivity tests should be the next steps.

Isolation and identification of endophytic bacteria and associated compound from Gloriosa superba and their antibacterial activities

Gloriosa superba L., which belongs to the genus Gloriosa and family Colchicaceae, is a climbing annual herb and tuberous poisonous tropical medicinal plant. This study was aimed to isolate possible endophytic bacteria from leaves, stems and tubers of Gloriosa superba. Thirty pure endophytic bacteria were isolated and subjected to biochemical characterization. Bacterial identification was conducted by Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The structure of the isolated compound was characterized. The antibacterial activity was also evaluated. Majority (21, 70 %) of the isolates were Gram-positive. Certain of them are spore formers. Based on MALDI-TOF MS, 26 of the isolates were identified as Bacillus spp. (65.4 %), Escherichia spp. (30.8 %) and Providencia spp. (3.9 %). A 1-undecene was isolated from culture filtrate of E. coli (GST-5). The ethyl acetate extracts (1000 μg/mL) of GSL-5 and GST-2 culture filtrates recorded maximum inhibition zone against E. coli (9.4 ± 0.6 mm) and S. aurous ATCC 25923T (8.4 ± 0.8 mm), respectively. The Pseudomonas aeruginosa ATCC 27853T was prone to all ethyl acetate extracts. A 1-undecene showed a moderate activity against E. coli ATCC 25922Tand P. aeruginosa ATCC 27853T at 50 μg/mL. The present finding would be a breakthrough to studies of similar works in Ethiopia since it may be for the first time.

Mycological Profile and Its Associated Factors Among Patients Suspected of Dermatophytosis at Bisidimo Hospital, Eastern Ethiopia

Background

Dermatophytosis is a common problem across the globe that is caused by a group of closely related fungi known as the dermatophytes that can invade keratinized tissues. It is a usual refractory infection and deleteriously affects the quality of life of humans. Despite the common presence of dermatophytes on the human host, research evidence in this area is limited.

Objective

Aimed to assess the mycological profile and its associated factors among patients suspected of dermatophytosis at Bisidimo Hospital, Eastern Ethiopia, from March to October 2021.

Methods

A cross-sectional study was conducted on 289 patients who visited the dermatology department of Bisidimo Hospital. Data were collected by reviewing patients’ charts and using a structured questionnaire to assess the associated factors of dermatophytosis. The patients’ medical charts were reviewed to assess chronic conditions. Skin, hair, or nail samples were collected and transported to Medical Microbiology Laboratory at Haramaya University Department of Medical Laboratory Sciences. Samples were inoculated into Potato dextrose agar and Sabouraud dextrose agar, and fungal isolates were identified morphologically and microscopically. Data were analyzed using Statistical Package for the Social Sciences version 26. Bivariate and multivariable logistic regression analyses with 95% confidence intervals were carried out to identify factors associated with dermatophytosis.

Results

The overall magnitude of dermatophytosis infection was 28.4% (95%CI: 23.2–32.2). Tinea capitis and tinea corporis were the common clinical presentations. The fungal isolates include Trichophyton species (68 isolates) and Epidermophyton species (17 isolates). Patients with features involving male sex (AOR = 2.5), age group of 1–10 years (AOR = 3.5), hypertension (AOR = 2.2), a family history of dermatophytosis (AOR = 2.0), and a history of animal contact (AOR = 1.5) had the increased odds of being infected with the dermatophytosis.

Conclusion

We found more than one in four patients assessed had dermatophytosis infection. It was considerably high in patients with a family history of the infection, animal contacts, hypertension, and below 10 years of age. Therefore, the control program for this disease should specifically target at a high risk populations, which must hinge on the evidence of molecular characterization and antifungal susceptibility patterns of the fungi.

Sero-Prevalence of HBV and its Associated Factors Among Healthcare Providers in Public Health Facilities in Eastern Ethiopia

Background:

Healthcare providers are in high occupational risk of Hepatitis B virus infection than that of the general population because of the high risk of occupational exposure to patients’ body fluids and accidental sharp injuries. There are no large facility-based studies conducted on the prevalence of HBV infection and its associated factors among health care providers in eastern Ethiopia.

Objective:

This study aimed at investigating the seroprevalence of Hepatitis B Virus and its associated factors among the healthcare providers in public health facilities in eastern Ethiopia.

Methods:

A facility-based cross-sectional study was conducted among 438 randomly selected healthcare providers in eastern Ethiopia from March to June 2018. Pretested structured questionnaire was used to collect data on socio-demographic characteristics and other risk factors. In addition, a 2.5 ml blood was collected and the serum was analyzed for Hepatitis B surface antigen using the Instant Hepatitis B surface antigen kit. Data were entered using Epidata version 3.1 and analyzed using SPSS statistical packages version 22. Descriptive summary measures were used. Bivariate and multivariable logistic regression was conducted at 95% CI. An association at P-value <.05 was considered statistically significant.

Results:

A total of 438 (92.02% response rate) health care providers have participated in this study. The prevalence of hepatitis B virus infection was 9.6%. There were no significant differences in the HBV infection rates among healthcare providers with respect to socio-demographic characteristics (P-value >.05). After adjusting for some variables, the following variables remained statistically significantly associated with HBsAg positive result in the multivariable analysis: exposure to body fluids (AOR = 3.0; 95% CI [1.25, 7.05]), history of needle stick injury (AOR = 4.70; 95% CI [2.10, 10.55]), history of operation/surgery (AOR = 4.88, 95% CI [1.43, 16.62]), history of multiple sexual partner (AOR = 7.48; 95% CI [2.08, 26.96]), and being unvaccinated (AOR = 6.09; 95% CI [2.75, 13.51]).

Conclusion:

This study showed a high prevalence of HBV infection among health care providers in eastern Ethiopia. This is significant because health professionals may be at increased risk of chronic complications and may also be source of infection for their clients and general population during their healthcare practice. Management commitment that should focus on occupational safety and health promotions is necessary.

Aerobic Bacterial Profile and Their Antibiotic Susceptibility Patterns of Sterile Body Fluids Among Patients at Hiwot Fana Specialized University Hospital, Harar, Eastern Ethiopia

BACKGROUND

Infections of sterile body fluids are susceptible to serious invasive bacterial infections and critical, with high morbidity and sequelae risk. This study has not been conducted previously in eastern Ethiopia.

OBJECTIVE

The present study was designed to determine the bacterial profile, associated factors, and their susceptibility to antimicrobial agents of isolates among patients with sterile body fluids at Hiwot Fana Specialized University Hospital, Harar, Eastern Ethiopia.

METHODS

Hospital-based cross-sectional study was conducted from April to June 2021 among 204 patients selected using a convenient sampling technique. Data were collected using a pretested structured questionnaire. All consenting patients submitting body fluid specimens for testing at the clinical laboratory were included and analyzed using standard microbiology methods. Antimicrobial susceptibility testing was performed using the disk diffusion method and interpreted as per Clinical and Laboratory Standards Institute guidelines. Data were double entered into Epi data version 4.6, exported, and analyzed using Statistical Package for Social Science version 25. Bivariate and multivariable logistic regressions were used to assess the association between outcome and predictor variables. P-value <0.05 was considered to be statistically significant.

RESULTS

The overall prevalence of bacteria among different sterile body fluid samples was 16.7% (95% CI: 12-22%). Most of the bacterial isolates (70.6%) were Gram-negative bacteria, mainly K. pneumoniae (26.5%) and E. coli (20.6%). Multidrug resistance was identified in 76.5% of the isolates. Being inpatient (AOR = 3.59; 95% CI: 1.52, 8.51) and turbid appearance (AOR = 4.35; 95% CI: 1.67, 11.29) were significantly associated with culture growth rate.

CONCLUSION

The prevalence of bacterial isolates in this study comprises about 17%. Gram-negative bacteria, particularly K. pneumoniae and E. coli, were the major etiologic agents. Being inpatient and the turbid appearance of the specimen were significantly associated with the culture-positive result. Significant numbers of multidrug-resistant bacteria were isolated, mainly against beta-lactams. Therefore, culture and susceptibility testing should be an integral part of the laboratory investigation.

Nasal carriage of MRSA among clinically affiliated undergraduate students at the College of Health and Medical Sciences, Haramaya University, Ethiopia

Medical and health science students are among the demographics most at risk from Methicillin-resistant Staphylococcus aureus (MRSA), which is a serious hazard to public health. The main reservoir for MRSA is the nasal cavity, and colonization of this area can raise the risk of infection and transmission in healthcare settings. This study aimed to assess the nasal carriage rate of MRSA among clinically affiliated students at Haramaya University, College of Health and Medicine Sciences, Ethiopia, from July to August 2022. An institution-based cross-sectional study of 250 study participants was conducted using a stratified random sampling methods. The data were collected via structured questionnaires. Nasal swabs were cultured on mannitol salt agar and blood agar at 37 °C for 24 h. Staphylococcus aureus was identified using catalase and coagulase tests. The MRSA was screened using the cefoxitin disk diffusion method on Muller Hinton agar. The data were entered and analyzed by SPSS version 25. Pearson's chi-square test was performed to predict associations between variables. A p value less than 0.05 was regarded as statistically significant. The nasal carriage rate of S. aureus was 8% (95% CI: 4.6-11.3%). The Nasal carriage rate of MRSA was 4.8% (95% CI: 2.1-7.4%). Overall, 4.8% of all the students were identified as MRSA carriers. MRSA carriage was high among medical students (33.3%). Nose-picking habit (X2 = 16.7, P = 0.001) and dormitory occupancy (X2 = 3.6, P = 0.045) were significantly associated with the MRSA rate. All the MRSA strains were resistant to penicillin and ampicillin. However, all the MRSA strains were susceptible to chloramphenicol and clindamycin. This study revealed that MRSA is a threat due to significant resistance. Nasal carriage is associated with nose picking and dorm occupancy. Encourage practices such as avoiding nose picking and maintaining personal cleanliness. Regular cleaning and disinfection of shared spaces can reduce the presence of MRSA.
