Determinants of Metabolic Syndrome Among Patients Receiving Anti-Retro-Viral Treatment in A Tertiary Hospital, Central Ethiopia: Unmatched Case-Control Study.

Purpose: Scaling up antiretroviral treatment (ART) reduces morbidity and mortality among people living with HIV/AIDS (PLHA). This success is challenged by the constellation of interrelated metabolic disorders such as metabolic syndrome (MetS). Given the changing ART regimens and schedules, increasing patient age and methodological limitations, existing evidence regarding the determinants of MetS remains inconclusive. Therefore, in the current study, we aimed to identify the determinants of MetS in patients receiving ART at a tertiary hospital in central Ethiopia. Patient and Methods: We conducted an unmatched case-control study that included 393 patients with a case-to-control ratio of 1 to 2. Data were collected by interviewing patients, reviewing charts, physical examinations, and laboratory testing. The data were entered into Epi-Info version 7.2 and analyzed using SPSS version 26. A binary logistic regression analysis was used to identify the determinants of MetS. The adjusted odds ratio (AOR) with a 95% confidence interval (CI) was used to estimate the strength of the association between MetS and its determinants. Statistical significance was set at p-value < 0.05. Results: In this study, higher odds of developing MetS were identified among patients aged 40-60 years (AOR 3.75; 95% CI: 1.66-8.49) and those older than 60 years (AOR 6.18; 95% CI: 2.12-17.95) than among those aged < 40 years. Similarly, higher odds were observed among patients who frequently consumed animal source foods than among those who consumed cereals or vegetables (AOR, 1.94; 95% CI, 1.03-3.63), those who had HIV lipodystrophy (AOR 1.73; 95% CI: 1.05-2.86), those who were treated with stavudine (AOR 3.08; 95% CI: 1.89-5.04), and those who were treated with zidovudine (AOR 1.71, 95% CI: 1.02-2.88) compared to their counterparts. Conclusion: Older age, diet from animal sources, exposure to zidovudine or stavudine, and the presence of lipodystrophy were independent determinants of MetS.

Prevalence of COVID-19 Vaccine Side Effects among Early-Vaccinated Healthcare Workers in Eastern Ethiopia.

Background: The Ministry of Health of Ethiopia launched the COVID-19 vaccination campaign in March 2021, with frontline healthcare workers as first-round recipients and a goal of vaccinating 20% of the population by the end of 2021. The study aims to estimate the prevalence of COVID-19 vaccination side effects among early vaccinated healthcare workers in Adama hospital medical college. Methods: A cross-sectional study was carried out between March and June 2021, following the vaccination of COVID-19 vaccine among healthcare workers in Adama hospital medical college. The study used a structured self-administered questionnaire and additional telephone surveys on items covering the participants' demographic data, local and systemic manifestations after vaccination. Results: A total of 540 health care workers and supportive staff were enrolled in this study. The overall any-symptom report after the first dose of ChAdOx1 nCoV- 19 vaccine was 84.3%. The majority (39.6%) of participants had both systemic and local symptoms and 25.7% had only local and 18.9% had only systemic symptoms. Injection site pain was the most prevalent side effect symptom (64.1%), followed by fatigue (35.7%), headache (28.9%), joint pain (26.5%), and muscle pain (21.5%). Conclusion: Vaccine side effects were common and found to be well-tolerated among the recipients of the first dose of ChAdOx1 nCoV-19 at Adama hospital medical college healthcare workers. The side effects were mainly mild to moderate. More side-effect profiles should be studied and disseminated to detect rare adverse reactions.

Characterization of HIV-1 drug resistance among patients with failure of second-line combined antiretroviral therapy in central Ethiopia.

BACKGROUND: As a consequence of the improved availability of combined antiretroviral therapy (cART) in resource-limited countries, an emergence of HIV drug resistance (HIVDR) has been observed. We assessed the prevalence and spectrum of HIVDR in patients with failure of second-line cART at two HIV clinics in central Ethiopia. METHODS: HIV drug resistance was analysed in HIV-1-infected patients with virological failure of second-line cART using the geno2pheno application. RESULTS: Among 714 patients receiving second-line cART, 44 (6.2%) fulfilled the criteria for treatment failure and 37 were eligible for study inclusion. Median age was 42 years [interquartile range (IQR): 20-45] and 62.2% were male. At initiation of first-line cART, 23 (62.2%) were WHO stage III, mean CD4 cell count was 170.6 (range: 16-496) cells/µL and median (IQR) HIV-1 viral load was 30 220 (7963-82 598) copies/mL. Most common second-line cART regimens at the time of failure were tenofovir disoproxil fumarate (TDF)-lamivudine (3TC)-ritonavir-boosted atazanavir (ATV/r) (19/37, 51.4%) and zidovudine (ZDV)-3TC-ATV/r (9/37, 24.3%). Genotypic HIV-1 resistance testing was successful in 35 (94.6%) participants. We found at least one resistance mutation in 80% of patients and 40% carried a protease inhibitor (PI)-associated mutation. Most common mutations were M184V (57.1%), Y188C (25.7%), M46I/L (25.7%) and V82A/M (25.7%). High-level resistance against the PI ATV (10/35, 28.6%) and lopinavir (LPV) (5/35, 14.3%) was reported. As expected, no resistance mutations conferring integrase inhibitor resistance were detected. CONCLUSIONS: We found a high prevalence of resistance mutations, also against PIs (40%), as the national standard second-line cART components. Resistance testing before switching to second- or third-line cART is warranted.

A Retrospective Comparative Study on Median Time to Sputum Culture Conversion in Multi-Drug Resistant Pulmonary Tuberculosis Patients in Pastoral and Non-Pastoral Settings in Southeast Oromia, Ethiopia.

PURPOSE: Sputum culture conversion to negative is an indicator of good interim treatment outcome. Pastoralist community has lesser access to healthcare services. This study aimed to compare the time to culture conversion (TTSCC) between the pastoral and non-pastoral settings and identify its determinants among drug-resistant pulmonary TB patients. PATIENTS AND METHODS: Four hundred forty-seven drug-resistant pulmonary TB patients were included from selected hospitals of southeastern Oromia, Ethiopia. Kaplan-Meier model using the Log rank test was fit to compute and compare median TTSCC between study participants from the pastoral and non-pastoral settings. The Cox proportional hazard model was fit to identify factors associated with the TTSCC. Adjusted hazard ratio (AHR) with a 95% confidence interval (CI) was used to report the strength of association. Statistical significance was declared at p < 0.05. RESULTS: The study participants' median age (interquartile range) was 29 (24-36) years. The overall median TTSCC among the current study participants was 67 (95% CI, 64-70) days. It was significantly different for patients from the pastoral and non-pastoral settings (p-value <0.001). The median TTSCC for patients from pastoral and non-pastoral settings was 101 (95% CI, 81-121) and 63 (95% CI, 61-64) days. To mention few determinants, patients from the pastoral setting had a 69% lower chance [HR = 0.31 (95% CI 0.24-0.41)] of shorter TTSCC than patients from the non-pastoral setting. Furthermore, patients with baseline body mass index greater than 18.5Kg/M2 had a 35% higher chance of shorter TTSCC [HR = 1.35 (95% CI 1.07-1.71)] compared to their counterparts. CONCLUSION: The median TTSCC among the study participants from pastoral was longer than those from non-pastoral setting. The pastoral setting, under-nutrition, previous exposure to anti-TB drugs and drug regimen categories were among the notable determinants of the TTSCC among our study participants. Hence, due attention should be given to patients with these determinants during the treatment.

Exploring community tuberculosis program in the pastoralist setting of Ethiopia: a qualitative study of community health workers' perspectives in Borena Zone, Oromia Region.

BACKGROUND: Pastoralist community accounts for a significant portion of the population in Ethiopia. This community is different from majority of the country's population. Access to TB prevention and control services is uneven in the country. The community TB program is designed to improve the access. Exploring the program performance from the perspectives of its implemters in a pastoral setting remains important. METHOD: We conducted a qualitative study using an interpretive description method in the pastoralist community setting of Ethiopia. Study participants were recruited from geographically dispersed areas. We collected data through in-depth interview using semi-structured interview guides and audio recordings during February 01-30, 2020. The guides were developed in consultation with TB program experts and clinicians treating TB patients in the study area. Notes were taken at the interviews to enrich transcription of the data. Principal investigator conducted the interview. The subsequent interviews were informed by emerging ideas from forgoing interview transcriptions and continued until data saturation was achieved. RESULTS: One hundred and fifty six codes, nine categories and three themes emanated. The first theme was inadequate community TB performance and some of its codes include inadequate presumptive TB case identification and compromised directly observed treatment short course service delivery. The second theme was factors contributing to the program performance. Community factors, lack of physical access to health facilities and indirect non-medical cost were some categories under this theme. The final theme was suggested solutions; and its categories include a need for active community involvement and modification of service delivery approaches. CONCLUSIONS: Community TB performance was inadequate in the pastoralist community. Multifaceted factors contributed to the inadequate program performance. Socioeconomic and access related factors were major contributers. Aligning the program to the context of the pastoralist community setting is required to improve the performance.

Lived experiences of tuberculosis patients and their implications for early tuberculosis case identification and management in pastoralist community setting: a qualitative study in Borena zone, Oromia region of Ethiopia.

BACKGROUND: Ethiopia has highly diversified population with notable socioeconomic and cultural differences. Regardless of the differences, short course directly observed treatment,where patients should take drugs under direct observasion of health care providers, is uniformly applied all over the country. Evidences are scarce on how well does this uniform approach fits with the pastoral community setting. The purpose of this study was to explore lived experiences of TB patients in the pastoral community under the uniform approach, and their implications to early case identification and management. METHOD: Qualitative method with phenomenological study design was undertaken to explore lived experiences of TB patients. Patients from all levels of health care (hospital, health center and health post) were included. Experience of both drug susceptible and drug resistant TB patients were documented. Twenty one patients, who consented to in the study, were selected by a convenience sampling method. In-depth interview was conducted using a semi-structured interview guide and the interview ended subsequent to information saturation. The interview was audio recorded; and field notes were also taken. Data analysis was done concurrently with the data collection using a word processor designed for qualitative text analysis. InductiveThematic analysis was undertaken to identify key themes. RESULTS: Twenty one patients (eight from hospitals, nine from health centers and four from health posts) were interviewed. Three of the eight hospital patients were on drug resistant tuberculosis (TB) treatment. Sixty two codes, five code categories and three themes emerged from the interviews. The three themes were health system, stigma and discrimination, and socioeconomic problem related experiences. Inaccessibility to health facilities due to scattered settlement and mobility, delay in care seeking TB symptoms, low index of suspecting TB by care providers, fear of stigma and indirect treatment related costs were some of the codes identified. CONCLUSION: TB patients in the pastoral setting were experiencing multifaceted challenges with the current application of 'one-size-fits-all' approach which implied hampered timely case identification and compromised patient management. Therefore, designing context appropriate intervention approach is required to ensure unprejudiced services.

Retention in care among HIV-positive patients initiating second-line antiretroviral therapy: a retrospective study from an Ethiopian public hospital clinic.

BACKGROUND: Access to second-line antiretroviral therapy (ART) for HIV-positive patients remains limited in sub-Saharan Africa. Furthermore, outcomes of second-line ART may be compromised by mortality and loss to follow-up (LTFU). OBJECTIVE: To determine retention in care among patients receiving second-line ART in a public hospital in Ethiopia, and to investigate factors associated with LTFU among adults and adolescents. DESIGN: HIV-positive persons with documented change of first-line ART to a second-line regimen were retrospectively identified from hospital registers, and data were collected at the time of treatment change and subsequent clinic visits. Baseline variables for adults and adolescents were analyzed using multivariate Cox proportional hazards models comparing subjects remaining in care and those LTFU (defined as a missed appointment of ≥90 days). RESULTS: A total of 383 persons had started second-line ART (330 adults/adolescents; 53 children) and were followed for a median of 22.2 months (the total follow-up time was 906 person years). At the end of study follow-up, 80.5% of patients remained in care (adults and adolescents 79.8%; children 85.7%). In multivariate analysis, LTFU among adults and adolescents was associated with a baseline CD4 cell count <100 cells/mm(3) and a first-line regimen failure that was not confirmed by HIV RNA testing. CONCLUSIONS: Although retention in care during second-line ART in this cohort was satisfactory, and similar to that reported from first-line ART programs in Ethiopia, our findings suggest the benefit of earlier recognition of patients with first-line ART failure and confirmation of suspected treatment failure by viral load testing.

Screening for cryptococcal antigenemia using the lateral flow assay in antiretroviral therapy-naïve HIV-positive adults at an Ethiopian hospital clinic.

BACKGROUND: Since treatment for latent cryptococcal infection (CI) before starting antiretroviral therapy (ART) reduces mortality in HIV-infected subjects, screening for cryptococcal antigen (CrAg) in blood is recommended for individuals with CD4 cell counts < 100 cells/µL in regions with high CI prevalence. We assessed CrAg screening using the lateral flow assay in HIV-infected adults eligible for ART in central Ethiopia. RESULTS: HIV-positive patients (age ≥ 18 years, CD4 cell count < 350 cells/µL and/or WHO stage IV, no current or previous ART) were recruited at Adama Regional Hospital, Ethiopia (February 2013 until March 2014). CrAg was determined in plasma by lateral flow assay. Among 129 included participants (median age 35 years, 64 % female) the median CD4 cell count was 210 cells/µL (interquartile range 110-309); 29 (23 %) had CD4 cell count < 100 cells/µL. Two (1.6 %) participants were CrAg-positive (CD4 cell counts 171 vs. 250 cells/µL), one of whom had clinically manifest cryptococcal meningitis at the time of testing. CONCLUSIONS: In contrast to two recent reports from Ethiopia, we found few cases of CI among ART-naïve adults. Our study, which is the first using lateral flow assay for CrAg screening in this country, illustrates the need of larger surveys of CI prevalence among ART-naïve patients before defining recommendations on CI screening.

Multidrug-resistant Mycobacterium tuberculosis and associated risk factors in Oromia Region of Ethiopia.

OBJECTIVE: The aim of this study was to determine risk factors for tuberculosis (TB) caused by multidrug-resistant Mycobacterium tuberculosis (MDR-TB) in Oromia Region, Ethiopia. METHODS: A 6-month case-control study was performed in 2013-14. Sputum samples and standardized questionnaire data (demographics, treatment, TB contact history, underlying disease, history of imprisonment) were collected from cases with suspected MDR-TB aged ≥ 18 years. Sputum was processed locally in the Oromia Public Health Laboratory using standard techniques. Data from MDR-TB cases and TB-positive controls were compared using logistic regression analysis. For each factor, the association with outcome variables was estimated by calculating the odds ratio (OR) together with the 95% confidence interval (95% CI). RESULTS: Of 439 suspected MDR-TB cases, 265 had a confirmed M. tuberculosis infection, of whom 88 (33%) had laboratory-confirmed MDR-TB. Over two-thirds (65%) were between 18 and 39 years of age. On multivariate analysis, an occupation of farming, known TB contact history, alcohol use, HIV infection, previous known TB history, and previous TB treatment outcome were predictors of MDR-TB. CONCLUSIONS: The rate of MDR-TB was high among suspected cases in the Oromia Region of Ethiopia. Local MDR-TB detection capacity and local epidemiology studies are essential to detect MDR-TB and guide the use of the sparse resources to optimize MDR-TB control. If TB is suspected, the presence of any of the above factors should alert Oromia Region clinicians and public health professionals to screen for MDR-TB.

The prevalence, clinical features and management of periphral neuropathy among diabetic patients in Tikur Anbessa and St. Paul's Specialized University Hospitals, Addis Ababa, Ethiopia.

BACKGROUND: Neuropathy is one of the common chronic complications of diabetes. There are many forms of diabetic neuropathy, one of which is distal symmetric polyneuropathy (DSP). There are only few data on diabetic neuropathy in Ethiopia. OBJECTIVE: The objectives of this study were to determine the prevalence of peripheral neuropathy, describe the clinical features, identify risk factors and treatment of neuropathy among diabetic patients. METHODS: A cross-sectional study was conducted at Tikur-Anbessa (TASH) and St. Paul's Specialized (SPH) University Hospitals in Addis Ababa. A total of 384 diabetic patients were selected using systematic random sampling method taking every third patients from clinics attendees from December 2009 to February 2010. Data were collected using structured questionnaires containing sociodemographic data, risk factors and UK neuropathy screening test score, Neurological examination for pain, Achilles tendon reflex, Vibration, and temperature. RESULTS: A total of 176 males and 208 females were included, 27% were type 1 and 73% were type 2 diabetic patients. The overall prevalence of distal symmetrical polyneuropathy (DSP) was 48.2% (53.6% in type 2 and 33.3% in type 1 diabetic patients). DSP was present in 37% of patient with duration of diabetes < 5yrs and 53% of those with diabetic duration > 10yrs. Autonomic neuropathy was identified in 30% of patients. Out of 185 patients with peripheral Neuropathy 136 (77%) had moderate and severe symptom scores; while 101 (58%) had moderate and severe sign scores. Type of Diabetes, duration of diabetes, systolic hypertension, and age were significantly associated with DSP (p < 0.05). Amitriptylline in 14 (28.6%), Carbamazepine in 4 (8.2%), and other NSAIDs 7 (12.2%) were used for treatment of painful neuropathy. CONCLUSIONS: Distal symmetrical polyneuropathy is common. The commonest presenting features are pain and loss of sensation. Duration of diabetes 10yrs, type 2 D, old age and hypertension were the major risk factors for DSP. Treatment of painful diabetic neuropathy was not optimal. RECOMMENDATIONSs: We recommend strengthening of routine screening for neuropathy, to emphasis on foot ulcer risk reduction, management of co-morbidities like hypertension and dyslipidemia, to optimize treatment of painful neuropathy.
