Determination of eligibility to antiretroviral therapy in resource limited settings using total lymphocyte counts, hemoglobin and body mass index among HIV positive patients

Background: Acquired Immunodeficiency Syndrome is a serious public health problem in Ethiopia. CD4+ T cell count testing is the standard method for determining eligibility for antiretroviral therapy. However, automation for CD4+ T cell count is not widely available in sub-Saharan Africa including Ethiopia.Objective: This study was to determine eligibility for antiretroviral therapy in resource-limited settings using total lymphocyte counts, hemoglobin and body mass index among HIV positive patients.Materials and methods: CD4+ T cell count was determined using Becton Dickinson FACS count analyzer. Total lymphocyte count and hemoglobin concentration were measured by a Cell Dyne 1800 hematology analyzer and body mass index was determined. Correlation of total lymphocyte count, hemoglobin and body mass index with CD4+ T cell count was determined by Pearson’s correlation coefficient and p-value.Results: The correlation between CD4+ T cell count and Total Lymphocyte Count (TLC) was not strong, but the association between CD4+ T cell count and TLC was highly significant and correlation between CD4+ T cell counts with hemoglobin were very weak. The sensitivity, specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) of TLC using threshold value of 1000 cells/mm3 for CD4+ T cell counts <350 cells/mm3 were 3% , 94%, 17% and 71%, respectively. Total lymphocyte count threshold of 1750 cells/mm3 were the better predictor of CD4+ T cell counts of <350 cells/mm3 when compared to < 200 cells/mm3.Conclusion: TLC showed weak correlation with CD4+ T cell counts but the association between CD4+ T cell count with TLC was significant (p<0.0001). The TLC threshold of 1750 cells/mm3 were the most accurate predictors of CD4+ T cell counts of <350 cells/mm3. Therefore, the significant association of TLC with CD4+ T cell count may suggest that TLC could be used as marker for CD4+ T cell count in determining anti-retroviral treatment initiation when CD4+ T cell count is not available particularly in rural settings where laboratory facilities are lacking

Magnitude and associated factors of virological failure among children on ART in Bahir Dar Town public health facilities, Northwest Ethiopia: a facility based cross-sectional study

Background Despite the rapid scale-up of antiretroviral therapy, virologic failure has become global public health concern and challenge, especially in developing countries. Viral load monitoring is an important approach to identify treatment failure and develop public health interventions in children receiving antiretroviral therapy. Thus, this study aims to assess the magnitude and associated factors of virological failure among children on antiretroviral therapy. Methods A facility-based cross-sectional study was conducted among 399 HIV-positive children on antiretroviral therapy from 2016 to 2019 in Bahir Dar Town public health facilities. Data were extracted from children’s charts using a standardized data extraction tool, adapted from ART intake and follow-up forms. Data were entered using Epi-Data Version 3.1, and analyzed using SPSS Version 25. Bivariable and multivariable binary logistic regression models were done to identify factors associated with virological failure. Variables with p-values < 0.25 were fitted into the multivariable analysis. Finally, variables with p-values <0.05 were considered as statistically significant factors. Results The period prevalence of virological failure was found to be 14.8% (95% CI: 11.5–19.3%). Opportunistic infections (AOR = 2.19, CI: 1.13–4.25), history of treatment interruption and restart (AOR = 2.21, CI: 1.09–4.54), younger age (AOR = 2.42, CI: 1.02–5.74), poor/fair ART adherence (AOR = 2.19, CI: 1.05–4.57), and advanced baseline WHO clinical staging (AOR = 2.32, CI: 1.14–4.74) were found to be factors significantly associated with virological failure. Conclusion The magnitude of virological failure among HIV-infected children remained high. Children with poor/fair ART adherence, history of treatment interruption, advanced baseline WHO clinical staging, younger age, and opportunistic infections were significantly associated with virologic failure. Thus, special attention should be given to children who had poor/fair ART adherence and presenting with opportunistic infections

Married women's decision making power on family planning use and associated factors in Mizan-Aman, South Ethiopia : a cross sectional study

Background: Women's use of family planning service is influenced by many factors, especially by their decision making power. A woman's decision-making power, be it individual or decision made in collaboration with a partner, is the most important factor in the use of family planning in a household. The purpose of this study was to assess the impact of women's decision making power on family planning use and its associated factors. Methods: A community-based cross-sectional study was conducted on married women in the child bearing age. The women who were living in Mizan city were selected using the simple random sampling method. Trained nurses collected the data by interview, using a structured and pre-tested questioner. Bivariable and multivariable binary logistic regression analysis was used to identify the associated factors, and the odds ratio with a 95 % CI was computed to assess the strength of the association. Collinearity was also assessed by looking at standard errors in the final fitted model. Result: Overall, more than two-thirds [67.2 %: 95 % CI (63-71 %)] of the married women were found to be more autonomous to decide family planning use. Secondary education [AOR: 9.04, 95 % CI: (4.50, 18.16)], government employment [AOR: 4.84, 95 % CI: (2.03, 11.52)], being wives of government employed spouses [AOR 2.71, 95 % CI: (1.24, 7.97)], having husbands with college or university education [AOR: 11.29, 95 % CI: (4.66, 27.35)], and being in the younger age [AOR: 0.27, 95 % CI :(0.09, 0.75)] were significantly associated with women's decision-making power on family planning. Conclusions: In this study, women had a high decision making power in family planning use. Age category (34-44-years), formal education, and occupational status had effects on women's decision making power. Promoting parental adult education and engaging women in out of house employment is essential to improve their decision making power in using family planning

Bacterial isolates and their antimicrobial susceptibility pattern among patients with external ocular infections at Borumeda hospital, Northeast Ethiopia

Background: Bacteria are major cause of ocular infections and possible loss of vision. The emergence of antimicrobial resistant bacteria increases the risk of treatment failure with potentially serious consequences. The aim of this study was to determine the prevalence of bacterial isolates and their antimicrobial susceptibility pattern among patients with external ocular infections. Methods: A cross sectional study was conducted among 160 patients with external ocular infections at Borumeda hospital, Northeast Ethiopia. Socio-demographic and clinical data were collected using structured questionnaire. External ocular specimens were collected using sterile swabs and inoculated on MacConkey agar, Chocolate agar and Blood agar culture Medias. Presumptive isolates were further identified by a series of biochemical tests. The antimicrobial susceptibility patterns of the isolates were determined by disk diffusion method. Result: The overall prevalence of bacterial pathogens among external ocular samples was 59.4 %. The majority of the isolates (93.7 %; 89/95) were Gram positive and the other 6.3 % (6/95) Gram negative bacteria. The proportion of coagulase negative Staphylococci among the Gram positive bacterial isolates was 53.7 % (n = 51/95). All Gram positive isolates were susceptible for vancomycin but 67.4 % (n = 60/95) of them were resistant against amoxicillin. Moreover, drug resistance to tetracycline, norfloxacylin, ceftriaxone and ciprofloxacin were observed among Gram negative bacteria isolates. Conclusion: The prevalence of bacterial pathogens among external ocular samples was high and the predominant isolate was coagulase negative Staphylococci. Exceptionally high amoxicillin resistance was observed among Gram positive bacterial isolates that may dictate to conduct drug susceptibility test routinely.Birtukan Shiferaw, Baye GelawEmail author, Abate Assefa, Yared Assefa and Zelalem Addi

High erythromycin-resistant Campylobacter jejuni and C. coli among humans and chickens in Africa

Human Campylobacter spp. enteritis is a common bacterial foodborne illness globally. C. jejuni and C. coli are implicated: chickens are carriers of these bacteria without showing clinical symptoms. The burden of antimicrobial resistant Campylobacter is increasing worldwide. However, there are limited data on the extent of antimicrobial resistance in Africa. Objective: This review aimed to estimate the pooled magnitude of antimicrobial resistance of Campylobacter jejuni and C. coli. Materials and methods: To fill this gap, we conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Checklist. Literature search used relevant terms and phrases combined using the Boolean operators. The databases PubMed, Google Scholar, Hinnari, and Google were used to find relevant articles. All necessary data were extracted using a standardized data extraction format by two individuals independently. A quality assessment of selected articles was made using Newcastle–Ottawa scale adapted for cross sectional studies. Result: A total 12 studies were identified by this systematic review and meta-analysis. Of 1,142 isolates documented in the papers, 858 (75.1%) were C. jejuni and 284 (24.9%) were C. coli. We found C. jejuni showed lowest resistance level (21.2%) to ciprofloxacin and highest resistance level to trimethoprim-sulfamethoxazole(78.2%) whereas C. coli showed lowest resistance level (18.3%) to ciprofloxacin and highest level of resistance (82.7%) to azithromycin. The overall pooled magnitude of erythromycin resistance C. jejuni and C. coli among in human and chicken subjects was 51.0% and 54.0%, respectively. Conclusion: This systematic review and meta-analysis found high pooled magnitude of erythromycin resistant C. jejuni and C. coli among isolates from both humans and chickens in Africa. More One Health research is needed to give a clear picture on antimicrobial resistance and transmission dynamics of Campylobacter spp. in Africa, covering both humans and poultry

Protocol for the evaluation of a complex intervention aiming at increased utilisation of primary child health services in Ethiopia: a before and after study in intervention and comparison areas.

BACKGROUND: By expanding primary health care services, Ethiopia has reduced under-five mor4tality. Utilisation of these services is still low, and concerted efforts are needed for continued improvements in newborn and child survival. "Optimizing the Health Extension Program" is a complex intervention based on a logic framework developed from an analysis of barriers to the utilisation of primary child health services. This intervention includes innovative components to engage the community, strengthen the capacity of primary health care workers, and reinforce the local ownership and accountability of the primary child health services. This paper presents a protocol for the process and outcome evaluation, using a pragmatic trial design including before-and-after assessments in both intervention and comparison areas across four Ethiopian regions. The study has an integrated research capacity building initiative, including ten Ph.D. students recruited from Ethiopian Regional Health Bureaus and universities. METHODS: Baseline and endline surveys 2 years apart include household, facility, health worker, and district health office modules in intervention and comparison areas across Amhara, Southern Nations Nationalities and Peoples, Oromia, and Tigray regions. The effectiveness of the intervention on the seeking and receiving of appropriate care will be estimated by difference-in-differences analysis, adjusting for clustering and for relevant confounders. The process evaluation follows the guidelines of the UK Medical Research Council. The implementation is monitored using data that we anticipate will be used to describe the fidelity, reach, dose, contextual factors and cost. The participating Ph.D. students plan to perform in-depth analyses on different topics including equity, referral, newborn care practices, quality-of-care, geographic differences, and other process evaluation components. DISCUSSION: This protocol describes an evaluation of a complex intervention that aims at increased utilisation of primary and child health services. This unique collaborative effort includes key stakeholders from the Ethiopian health system, the implementing non-governmental organisations and universities, and combines state-of-the art effectiveness estimates and process evaluation with capacity building. The lessons learned from the project will inform efforts to engage communities and increase utilisation of care for children in other parts of Ethiopia and beyond.

High seroprevalence of anti-SARS-CoV-2 antibodies among Ethiopian healthcare workers

BACKGROUND: COVID-19 pandemic has a devastating impact on the economies and health care system of sub-Saharan Africa. Healthcare workers (HWs), the main actors of the health system, are at higher risk because of their occupation. Serology-based estimates of SARS-CoV-2 infection among HWs represent a measure of HWs' exposure to the virus and could be used as a guide to the prevalence of SARS-CoV-2 in the community and valuable in combating COVID-19. This information is currently lacking in Ethiopia and other African countries. This study aimed to develop an in-house antibody testing assay, assess the prevalence of SARS-CoV-2 antibodies among Ethiopian high-risk frontline HWs. METHODS: We developed and validated an in-house Enzyme-Linked Immunosorbent Assay (ELISA) for specific detection of anti-SARS-CoV-2 receptor binding domain immunoglobin G (IgG) antibodies. We then used this assay to assess the seroprevalence among HWs in five public hospitals located in different geographic regions of Ethiopia. From consenting HWs, blood samples were collected between December 2020 and February 2021, the period between the two peaks of COVID-19 in Ethiopia. Socio-demographic and clinical data were collected using questionnaire-based interviews. Descriptive statistics and bivariate and multivariate logistic regression were used to determine the overall and post-stratified seroprevalence and the association between seropositivity and potential risk factors. RESULTS: Our successfully developed in-house assay sensitivity was 100% in serum samples collected 2- weeks after the first onset of symptoms whereas its specificity in pre-COVID-19 pandemic sera was 97.7%. Using this assay, we analyzed a total of 1997 sera collected from HWs. Of 1997 HWs who provided a blood sample, and demographic and clinical data, 51.7% were females, 74.0% had no symptoms compatible with COVID-19, and 29.0% had a history of contact with suspected or confirmed patients with SARS-CoV-2 infection. The overall seroprevalence was 39.6%. The lowest (24.5%) and the highest (48.0%) seroprevalence rates were found in Hiwot Fana Specialized Hospital in Harar and ALERT Hospital in Addis Ababa, respectively. Of the 821 seropositive HWs, 224(27.3%) of them had a history of symptoms consistent with COVID-19 while 436 (> 53%) of them had no contact with COVID-19 cases as well as no history of COVID-19 like symptoms. A history of close contact with suspected/confirmed COVID-19 cases is associated with seropositivity (Adjusted Odds Ratio (AOR) = 1.4, 95% CI 1.1-1.8; p = 0.015). CONCLUSION: High SARS-CoV-2 seroprevalence levels were observed in the five Ethiopian hospitals. These findings highlight the significant burden of asymptomatic infection in Ethiopia and may reflect the scale of transmission in the general population
