Bacterial profile and antimicrobial resistance patterns of infected diabetic foot ulcers in sub-Saharan Africa: a systematic review and meta-analysis.

The number of diabetic foot ulcer patients is substantially increasing, with the rapidly rising burden of diabetic mellitus in sub-Saharan Africa. The data on the regional prevalence of diabetic foot ulcer infecting bacteria and their antimicrobial resistance patterns is crucial for its proper management. This systematic review and meta-analysis determined the pooled prevalence of bacterial profiles and antimicrobial resistance patterns of infected diabetic foot ulcers in sub-Saharan Africa. A comprehensive search of the literature was performed on CINAHL, EMBASE, Google Scholar, PubMed, Scopus, and Web of Science databases. Critical appraisal was done using the Joanna Briggs Institute's tool for prevalence studies. A pooled statistical meta-analysis was conducted using STATA Version 17.0. The I2 statistics and Egger's test were used to assess the heterogeneity and publication bias. The pooled prevalence and the corresponding 95% confidence interval of bacterial profiles and their antimicrobial resistance patterns were estimated using a random effect model. Eleven studies with a total of 1174 study participants and 1701 bacteria isolates were included. The pooled prevalence of the most common bacterial isolates obtained from DFU were S. aureus (34.34%), E. coli (21.16%), and P. aeruginosa (20.98%). The highest pooled resistance pattern of S. aureus was towards Gentamicin (57.96%) and Ciprofloxacin (52.45%). E.coli and K. Pneumoniae showed more than a 50% resistance rate for the most common antibiotics tested. Both gram-positive and gram-negative bacteria were associated with diabetic foot ulcers in sub-Saharan Africa. Our findings are important for planning treatment with the appropriate antibiotics in the region. The high antimicrobial resistance prevalence rate indicates the need for context-specific effective strategies aimed at infection prevention and evidence-based alternative therapies.

Malaria and Helminthic Co-Infection during Pregnancy in Sub-Saharan Africa: A Systematic Review and Meta-Analysis.

Malaria and helminthic co-infection during pregnancy causes fetomaternal haemorrhage and foetal growth retardation. This study determined the pooled burden of pregnancy malaria and helminthic co-infection in sub-Saharan Africa. CINAHL, EMBASE, Google Scholar, Scopus, PubMed, and Web of Science databases were used to retrieve data from the literature, without restricting language and publication year. The Joanna Briggs Institute's critical appraisal tool for prevalence studies was used for quality assessment. STATA Version 14.0 was used to conduct the meta-analysis. The I2 statistics and Egger's test were used to test heterogeneity and publication bias. The random-effects model was used to estimate the pooled prevalence at a 95% confidence interval (CI). The review protocol has been registered in PROSPERO, with the number CRD42019144812. In total, 24 studies (n = 14,087 participants) were identified in this study. The pooled analysis revealed that 20% of pregnant women were co-infected by malaria and helminths in sub-Saharan Africa. The pooled prevalence of malaria and helminths were 33% and 35%, respectively. The most prevalent helminths were Hookworm (48%), Ascaris lumbricoides (37%), and Trichuris trichiura (15%). Significantly higher malaria and helminthic co-infection during pregnancy were observed. Health systems in sub-Saharan Africa must implement home-grown innovative solutions to underpin context-specific policies for the early initiation of effective intermittent preventive therapy.

Proportion and trend of primary resistance among Multidrug resistant Tuberculosis patients in Ethiopia.

Background: Evidence based information on the proportion & trend of primary resistance among multidrug resistance (MDR) TB patients is important for designing effective strategies in the control of the disease. Methods: A retrospective record review of 348 MDR/RR-TB patients treated at All African Leprosy Rehabilitation & Training (ALERT) Center from January 2014- December 2018. Categorical variables were compared using Chi-square/Fisher exact test as appropriate. Trend analysis was done using chi-square & linear regression. Logistic regression analysis was done to determine the factors associated with primary MDR/RR TB. Adjusted Odds Ratio (AOR) with 95% CI and p value < 5% were used to report factors associated. Result: Proportion of primary resistance among MDR/RR TB patients was 25.9% with 95% CI 21.3-30.3%. The proportion increased form 9.7% in 2014 to 43.4% in 2018 at a yearly increasing rate of 9.27%. Contact history to TB patient & year of diagnosis 2017 and 2018 were significantly associated with primary resistance AOR (95% CI) & p value 4.15(1.75-9.84) p = 0.001, 3.87(1.44-10.39) p = 0.007, 3.43(1.20-9.84) p = 0.022 respectively. Conclusion: The study revealed a high proportion of primary resistance among MDR/RR TB during the study period with a linearly increasing fashion thus a need for due attention in the efforts to control MDR TB.

Caregiver and child factors predicting HIV status disclosure among children enrolled on ART: a cross-regional study in Addis Ababa and Oromia, Ethiopia.

INTRODUCTION: The World Health Organization recommends that for children of school age who are HIV-positive, their HIV status should be disclosed. The purpose of this study was to get a better understanding of disclosure rates among school-aged children in Ethiopia and to investigate the variables amongst caregivers and children predicting disclosure/non-disclosure. METHODS: Data from 231 children were collected prospectively through a structured questionnaire after initiation of ART treatment. Data were analysed with χ2 test for comparison and logistic regression to verify the prediction of independent variables with the child's HIV status disclosure. RESULTS: Child age, caregiver marital status and caregiver residence were significantly associated with disclosure at 6 months. Similarly, child age, caregiver marital status and caregiver-child relationship were found to be significantly associated with disclosure at 12 months. Child age greater than nine years at 6 months (aOR 8.5, 95% CI: 2.5-29) and at 12 months (aOR 5.3, 95% CI: 1.8-16) were found to be significantly associated with disclosure. Furthermore, at 6 months, children with caregivers who had a partner they were not married to were more likely to disclose the HIV status to the child. This study suggests that paediatrics HIV care and treatment should consider these issues through contextualized strategies on child HIV disclosure and related challenges. Large-scale studies are required to better generalize on the subject.

Prevalence of antimicrobial resistance and its clinical implications in Ethiopia: a systematic review.

BACKGROUND: Antimicrobial resistance is one of the major public health challenges in Ethiopia. However, there is no comprehensive summary of existing AMR data in the country. AIM: To determine the prevalence of antimicrobial resistance and its clinical implications in Ethiopia. METHODS: A systematic literature search was performed on the PubMed/Medline database. Original studies on antimicrobial resistance conducted in Ethiopia between 1st January 2009 and 31st July 2019 were included. The outcome measure was the number of isolates resistant to antimicrobial agents in terms of specific pathogens, and disease condition. Data was calculated as total number of resistant isolates relative to the total number of isolates per specific pathogen and medication. RESULTS: A total of 48,021 study participants enrolled from 131 original studies were included resulting in 15,845 isolates tested for antimicrobial resistance. The most common clinical sample sources were urine (28%), ear, nose, and throat discharge collectively (27%), and blood (21%). All the studies were cross-sectional and 83% were conducted in hospital settings. Among Gram-positive bacteria, the reported level of resistance to vancomycin ranged from 8% (Enterococcus species) to 20% (S. aureus). E. coli, K. pneumoniae and P. aeruginosa were the most common Gram-negative pathogens resistant to key antimicrobial agents described in the national standard treatment guideline and were associated with diverse clinical conditions: urinary tract infections, diarrhea, surgical site infections, pneumonia, ocular infections, and middle ear infections. CONCLUSION: Overall, there is a high prevalence of antimicrobial resistance in Ethiopia. Empirical treatment of bacterial infections needs to be guided by up-to-date national guidelines considering local antimicrobial susceptibility patterns. Equipping diagnostic laboratories with culture and drug susceptibility testing facilities, and establishing a strong antimicrobial stewardship program should be high priorities.

Tuberculosis Treatment Outcome and Predictors in Africa: A Systematic Review and Meta-Analysis.

This review aimed to summarize and estimate the TB treatment success rate and factors associated with unsuccessful TB treatment outcomes in Africa. Potentially eligible primary studies were retrieved from PubMed and Google Scholar. The risk of bias and quality of studies was assessed using The Joanna Briggs Institute's (JBI) appraisal criteria, while heterogeneity across studies was assessed using Cochran's Q test and I2 statistic. Publication bias was checked using the funnel plot and egger's test. The protocol was registered in PROSPERO, numbered CRD42019136986. A total of 26 eligible studies were considered. The overall pooled estimate of TB treatment success rate was found to be 79.0% (95% CI: 76-82%), ranging from 53% (95% CI: 47-58%) in Nigeria to 92% (95% CI: 90-93%) in Ethiopia. The majority of unsuccessful outcomes were attributed to 48% (95% CI: 40-57%) death and 47% (95% CI: 39-55%) of defaulter rate. HIV co-infection and retreatment were significantly associated with an increased risk of unsuccessful treatment outcomes compared to HIV negative and newly diagnosed TB patients with RR of 1.53 (95% CI: 1.36-1.71) and 1.48 (95% CI: 1.14-1.94), respectively. TB treatment success rate was 79% below the WHO defined threshold of 85% with significant variation across countries. Countries need to explore contextual underlining factors and more effort is required in providing TB preventive treatment, improve case screening and linkage for TB treatment among HIV high-risk groups and use confirmatory TB diagnostic modality. Countries in Africa need to strengthen counseling and follow-up, socio-economic support for patients at high risk of loss to follow-up and poor treatment success is also crucial for successful TB control programs.

Comorbidity of Geo-Helminthes among Malaria Outpatients of the Health Facilities in Ethiopia: Systematic Review and Meta-Analysis.

BACKGROUND: Coinfection of malaria and intestinal helminths affects one third of the global population, largely among communities with severe poverty. The spread of these parasitic infections overlays in several epidemiological locations and the host shows different outcomes. This systematic review and meta-analysis determine the pooled prevalence of malaria and intestinal helminthiases coinfections among malaria suspected patients in Ethiopia. METHODS: Primary studies published in English language were retrieved using appropriate search terms on Google Scholar, PubMed/MEDLINE, CINHAL, Scopus, and Embase. The Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used for critical appraisal of studies. A pooled statistical meta-analysis was conducted using STATA Version 14.0 software. The heterogeneity and publication bias were assessed using the I2 statistics and Egger's test, respectively. Duval and Tweedie's nonparametric trim and fill analysis using the random-effect analysis. The Random effects model was used to estimate the summary prevalence of comorbidity of malaria and soil transmitted helminthiases and the corresponding 95% confidence intervals (CI). The review protocol has registered in PROSPERO number CRD42019144803. RESULTS: We identified ten studies (n = 6633 participants) in this study. The overall pooled result showed 13% of the ambulatory patients infected by malaria and intestinal helminths concurrently in Ethiopia. The pooled prevalence of Plasmodium falciparum and Plasmodium vivax, and mixed infections were 12, 30, and 6%, respectively. The most common intestinal helminth parasites detected were Hookworm, Ascaris lumbricoides, and Tirchuris trichiura. CONCLUSIONS: The comorbidity of malaria and intestinal helminths causes lower hemoglobin level leading to maternal anemia, preterm delivery, and still birth in pregnant women and lactating mother. School-aged children and neonates coinfected by plasmodium species and soil transmitted helminths develop cognitive impairment, protein energy malnutrition, low birth weight, small for gestational age, and gross motor delay. The Ministry of Health of Ethiopia and its international partners working on malaria elimination programs should give more emphasis to the effect of the interface of malaria and soil transmitted helminths, which calls for an integrated disease control and prevention.

Rates and predictors of attrition among children on antiretroviral therapy in Ethiopia: A prospective cohort study.

INTRODUCTION: Attrition from antiretroviral therapy (ART) programmes is a critical challenge among children receiving care in resource-limited settings. Our objective was to determine the rates and predictors of attrition among children on ART in Ethiopia. METHODS: Between December 2014 and September 2016, we conducted a prospective cohort study in eight health facilities in Ethiopia. Eligibility criteria included age 3 months-14 years; being on ART for not more than a month. Outcome was attrition due to death and/or loss to follow-up. Predictor variables were child clinical and socio-demographic characteristics, and caregiver socio-demographic characteristics. We used Cox Regression analyses to examine the association between predictors and outcome. RESULTS: Of 309 children, 304 were included, 52% were male. Their median age was 9 years (Inter-quartile range, IQR, 6-12). At ART initiation, their median CD4 was 362 cells/mm3 (IQR 231-499); and 74.3% had WHO stage 1 or 2 disease. During 287.7 person-years of observation (PYO), 24 attritions were recorded, yielding an attrition rate of 8.3 per 100 PYO (95% CI 5.4-12.1). Of these, six children were reported dead, leading to a mortality rate of 2.1 per 100 PYO (95% CI 0.8-4.3). Eighteen were lost to follow-up (LTFU) leading to LTFU rate of 6.26 per 100 PYO (95% CI: 3.83-9.70). The majority, 14 (58%) of attrition occurred during the first six months of treatment. Age below three years [aHR] = 5.14 (95% CI: 2.07-12.96), rural residence (aHR = 3.97, 95% CI: 1.34-11.78) and baseline Hgb in g/dl < 10 g/dl [aHR] = 5.68 (95% CI: 2.03-6.23) predicted higher risk of attrition. Baseline Hgb < 10 g/dl (aHR = 16.63, 95% CI: 1.64-168.4) and WHO stage III or IV (aHR = 12.25, 95% CI: 1.26-119.05) predicted the death of the child. Higher attrition was documented among children of both biological parents alive and biologically related close family caregivers. CONCLUSION: Younger children, those from rural areas, and children with anaemia were at higher risk of attrition, especially during the early months of treatment, and therefore should be prioritized during treatment follow-up. Further studies should examine underlying reasons for higher attrition.

Hope for the Future But Fear the Risk of Stigma: Ethiopian Family Caregivers' Lived Experience of Caring for Their HIV Positive Child Two Years After Starting Antiretroviral Treatment.

Family caregivers are believed to be the primary source of support for HIV-affected children. There is limited evidence about practices of support for caregivers, to strengthen them and to enhance the welfare of HIV positive children, especially in African settings. Our aim was therefore to illuminate caregivers' lived experiences of caring for a child in Ethiopia 2 years after the child was enrolled in antiretroviral therapy. Qualitative interviews with 18 family caregivers of 18 children were performed and analyzed using an inductive design with a hermeneutic phenomenological approach. The family caregivers' lived experience was shown in two main themes comprising "lifelong medication gives hope for the future" and "support challenged by the fear of stigma." The family caregivers experienced hope and dreams for the future as they saw their child as healthy and they had regained normality in life after the child's diagnosis. The caregivers still feared the disclosure of the child's diagnosis, which gave rise to conflicts with the child, the family, and society. Good quality support from the healthcare staff lightened their burdens. Further studies are recommended on the strategies of stigma reduction and developing need-specific modalities to support caregivers in the community.

Caregiver-reported antiretroviral therapy non-adherence during the first week and after a month of treatment initiation among children diagnosed with HIV in Ethiopia.

To achieve optimal virologic suppression for children undergoing antiretroviral therapy (ART), adherence must be excellent. This is defined as taking more than 95% of their prescribed doses. To our knowledge, no study in Ethiopia has evaluated the level of treatment adherence at the beginning of the child's treatment. Our aim was therefore to evaluate caregiver-reported ART non-adherence among children and any predictors for this during the early course of treatment. We conducted a prospective cohort study of 306 children with HIV in eight health facilities in Ethiopia who were registered at ART clinics between 20 December 2014 and 20 April 2015. The adherence rate reported by caregivers during the first week and after a month of treatment initiation was 92.8% and 93.8%, respectively. Our findings highlight important predictors of non-adherence. Children whose caregivers were not undergoing HIV treatment and care themselves were less likely to be non-adherent during the first week of treatment (aOR = 0.17, 95% CI: 0.04, 0.71) and the children whose caregivers did not use a medication reminder after one month of treatment initiation (aOR = 5.21, 95% CI: 2.23, 12.16) were more likely to miss the prescribed dose. Moreover, after one month of the treatment initiation, those receiving protease inhibitor (LPV/r) or ABC-based treatment regimens were more likely to be non-adherent (aOR = 12.32, 95% CI: 3.25, 46.67). To promote treatment adherence during ART initiation in children, particular emphasis needs to be placed on a baseline treatment regimen and ways to issue reminders about the child's medication to both the health care system and caregivers. Further, large scale studies using a combination of adherence measuring methods upon treatment initiation are needed to better define the magnitude and predictors of ART non-adherence in resource-limited settings.

Surviving Overwhelming Challenges: Family Caregivers' Lived Experience of Caring for a Child Diagnosed with HIV and Enrolled in Antiretroviral Treatment in Ethiopia.

Family caregivers play a critical role in caring for children living with HIV, however, there is little knowledge about their experiences. The aim of this study was to illuminate the family caregivers' lived experiences of caring for a child when he or she has been diagnosed with HIV and enrolled to antiretroviral treatment. Qualitative interviews with 21 family caregivers of 21 children diagnosed with HIV were analyzed using an inductive design with a hermeneutic phenomenological approach. The caregivers' experience were articulated in 5 subthemes under the main theme of "Surviving overwhelming challenges": "Committed care-giving," "Breaking the family life," "Caring burdens," "Confronting conflicts," and "Living with worry." Despite the difficult situation the family caregivers experienced with extensive worry, caring burdens, and disrupted family and social networks, they were committed caregivers. They were empowered by their belief in God but also by their strong belief in the child's treatment and support from healthcare workers. The healthcare system needs to consider possible ways to support the family caregivers during child's HIV diagnosis and treatment initiation as part of a continuum of care.
