The burden of severe asthma in sub-Saharan Africa: Findings from the African Severe Asthma Project.

Background: Severe asthma is associated with high morbidity, mortality, and health care utilization, but its burden in Africa is unknown. Objective: We sought to determine the burden (prevalence, mortality, and activity and work impairment) of severe asthma in 3 countries in East Africa: Uganda, Kenya, and Ethiopia. Methods: Using the American Thoracic Society/European Respiratory Society case definition of severe asthma, we analyzed for the prevalence of severe asthma (requiring Global Initiative for Asthma [GINA] steps 4-5 asthma medications for the previous year to achieve control) and severe refractory asthma (remains uncontrolled despite treatment with GINA steps 4-5 asthma medications) in a cohort of 1086 asthma patients who had been in care for 12 months and had received all GINA-recommended medications. Asthma control was assessed by the asthma control questionnaire (ACQ). Results: Overall, the prevalence of severe asthma and severe refractory asthma was 25.6% (95% confidence interval [CI], 23.1-28.3) and 4.6% (95% CI, 3.5-6.0), respectively. Patients with severe asthma were (nonsevere vs severe vs severe refractory) older (39, 42, 45 years, P = .011), had high skin prick test reactivity (67.1%, 76.0%, 76.0%, P = .004), had lower forced expiratory volume in 1 second percentage (81%, 61%, 55.5%, P < .001), had lower quality of life score (129, 127 vs 121, P < .001), and had higher activity impairment (10%, 30%, 50%, P < .001). Factors independently associated with severe asthma were hypertension comorbidity; adjusted odds ratio 2.21 (1.10-4.47), P = .027, high bronchial hyperresponsiveness questionnaire score; adjusted odds ratio 2.16 (1.01-4.61), P = .047 and higher ACQ score at baseline 2.80 (1.55-5.08), P = .001. Conclusion: The prevalence of severe asthma in Africa is high and is associated with high morbidity and poor quality of life.

Predictors of ICU Mortality among Mechanically Ventilated Patients: An Inception Cohort Study from a Tertiary Care Center in Addis Ababa, Ethiopia.

Background: Mechanical ventilation is a life-saving intervention for patients with critical illnesses, yet it is associated with higher mortality in resource-constrained settings. This study intended to determine factors associated with the mortality of mechanically ventilated adult intensive care unit (ICU) patients. Methods: A one-year retrospective inception cohort study was conducted using manual chart review in ICU patients (age >13) admitted to Tikur Anbessa Specialized Hospital (Addis Ababa, Ethiopia) from September 2019 to September 2020; mechanically ventilated patients were followed to hospital discharge. Demographic, clinical, and outcome data were collected; logistic regression was used to determine mortality predictors in the ICU. Result: A total of 160 patients were included; 85/160 (53.1%) were females and the mean (SD) age was 38.9 (16.2) years. The commonest indication for ICU admission was a respiratory problem (n = 97/160, 60.7%). ICU and hospital mortality were 60.7% (n = 97/160) and 63.1% (n = 101/160), respectively. Coma (Glasgow Coma Score <8 or 7 with an endotracheal tube (7T)) (adjusted odds ratio [AOR] 6.3, 95% confidence interval 1.19-33.00), cardiovascular diagnosis (AOR 5.05 [1.80-14.15]), and a very low serum albumin level (<2 g/dl) (AOR 4.9 [1.73-13.93]) were independent predictors of mortality (P < 0.05). The most commonly observed complication was ICU acquired infection (n = 48, 30%). Conclusions: ICU mortality in ventilated patients is high. Coma, a very low serum albumin level (<2 g/dl), and cardiovascular diagnosis were independent predictors of mortality. A multifaceted approach focused on developing and implementing context appropriate guidelines and improving skilled healthcare worker availability may prove effective in reducing mortality.

The yield of chest X-ray based versus symptom-based screening among patients with diabetes mellitus in public health facilities in Addis Ababa, Ethiopia.

Background: Patients with diabetes mellitus (DM) are at increased risk of developing TB, but the best screening algorithm for early detection and treatment of TB remains unknown. Our objective was to determine if combining routine chest X-ray screening could have a better yield compared with symptom-based screening alone. Methods: We conducted this cross-sectional study between September 2020 and September 2021 in 26 public health facilities in Addis Ababa, Ethiopia. All DM patients attending the clinics during the study period were offered chest X-ray and symptom screening simultaneously followed by confirmatory Xpert testing. We analyzed the number and proportion of patients with TB by the diagnostic algorithm category and performed binary logistic regression analysis to identify predictors of TB diagnosis. Results: Of 7394 patients screened, 54.6 % were female, and their median age was 53 years. Type-2 diabetes accounted for 89.6 % of all participants of the patients. Of 172 symptomatic patients, chest X-ray suggested TB in 19, and 11 of these were confirmed to have TB (8 bacterilogicially confirmed and 3 clinically diagnosed). Only 2 of the 152 asymptomatic patients without X-ray findings had TB (both bacteriologically confirmed). X-ray was not done for one patient. On the other hand, 28 of 7222 symptom-negative patients had X-ray findings suggestive of TB, and 7 of these were subsequently confirmed with TB (6 clinically diagnosed). When combined with 8 patients who were on treatment for TB at the time of the screening, the overall point prevalence of TB was 380 per 100,000. The direct cost associated with the X-ray-based screening was 42-times higher. Conclusion: Chest X-ray led to detection of about a third of TB patients which otherwise would have been missed but the algorithm is more expensive. Its full cost implication needs further economic evaluation.

Assessment of hypertension and other factors associated with the severity of disease in COVID-19 pneumonia, Addis Ababa, Ethiopia: A case-control study.

BACKGROUND: Various reports suggested that pre-existing medical illnesses, including hypertension and other demographic, clinical, and laboratory factors, could pose an increased risk of disease severity and mortality among COVID-19 patients. This study aimed to assess the relation of hypertension and other factors to the severity of COVID-19 pneumonia in patients discharged from Eka Kotebe Hospital in June-September, 2020. METHODS: This is a single-center case-control study of 265 adult patients discharged alive or dead, 75 with a course of severe COVID-19 for the cases arm and 190 with the non-severe disease for the control arm. Three age and sex-matched controls were selected randomly for each patient on the case arm. Chi-square, multivariable binary logistic regression, and odds ratio (OR) with a 95% confidence interval was used to assess the association between the various factors and the severity of the disease. A p-value of <0.05 is considered statistically significant. RESULTS: Of the 265 study participants, 80% were male. The median age was 43 IQR(36-60) years. Both arms had similar demographic characteristics. Hypertension was strongly associated with the severity of COVID-19 pneumonia based on effect outcome adjustment (AOR = 2.93, 95% CI 1.489, 5.783, p-value = 0.002), similarly, having diabetes mellitus (AOR = 3.17, 95% CI 1.374, 7.313, p-value<0.007), chronic cardiac disease (AOR = 4.803, 95% CI 1.238-18.636, p<0.023), and an increase in a pulse rate (AOR = 1.041, 95% CI 1.017, 1.066, p-value = 0.001) were found to have a significant association with the severity of COVID-19 pneumonia. CONCLUSIONS: Hypertension was associated with the severity of COVID-19 pneumonia, and so were diabetes mellitus, chronic cardiac disease, and an increase in pulse rate.

High rates of undiagnosed diabetes mellitus among patients with active tuberculosis in Addis Ababa, Ethiopia.

Background: Tuberculosis (TB) and diabetes mellitus (DM) have negative synergistic impact on each other. Global guidelines recommend collaborative efforts to address this synergy, but implementation has been slow. Part of the reason is lack of adequate evidence on the operational feasibility of existing tools and mechanisms of collaboration. The objective of this study was to assess the yield of DM screening among TB patients using risk scoring tools combined with blood tests as a feasible strategy for early detection to improve TB/DM treatment outcomes. Methods: Between September 2020 and December 2021, we conducted a cross-sectional study among patients receiving TB treatment in public health facilities in Addis Ababa, Ethiopia. Trained health workers collected data on symptoms and risk scoring checklists before testing for random and fasting blood glucose levels. We used logistic regression analyses techniques to determine factors associated with increased DM detection. A receiver-operating characteristic curve was constructed to determine the performance of the risk scoring checklist. Results: Of 2381 TB patients screened, 197 (8.3%) had DM of which 48.7% were newly diagnosed. Having a family history of DM predicted DM with Odds Ratio (OR) of 5.36 (95% Confidence Interval, [3.67, 7.83]) followed by age ≥ 45 years (OR = 4.64, [3.18, 6.76]). Having one or more "symptoms" of DM was a significant predictor (OR 2.88, 95% CI, 2.06-4.01). Combining risk scores with symptoms predicted DM diagnosis with sensitivity of 94.7%, but specificity was low at 29.4%. In patients with known treatment outcome status, death rate was high. Conclusions: Almost a half of TB patients with DM did not know their status. A simple tool that combined risk factors with symptoms accurately predicted a subsequent diagnosis of DM. Such tools can help avoid high rates of death among TB patients suffering from DM through early detection.

Impact of COVID-19 on population health and economic wellbeing in Ethiopia: A national pilot survey.

Introduction: The COVD-19 pandemic has resulted in unprecedented global health and economic crisis, particularly in countries struggling with poverty. We conducted a national survey to understand the economic and health impacts of COVID-19 in Ethiopia. Methods: A pilot, population-based, cross-sectional survey was conducted among adults randomly selected from the Ethio Telecom list of mobile phone numbers. Participants underwent a comprehensive phone interview about the impact of COVID-19 on their economic well-being and the health-related risks associated with COVID-19. Results: Of 4,180 calls attempted, 1194 were answered, of which a successful interview was made with 614 participants. COVID-19 affected the family income of 343 [55.9%] participants, 56 [9.1%] lost their job, 105 [17.1%] perceived high stress in their household, and 7 [1.14%] reported death in their family in the past month. The odds of having a decreased income due to COVID-19 were 2.4 times higher among self-employed [adjusted odds ratio (AOR) 2.4, 95% CI (1.58-3.77)] and 2.8 times higher among unemployed [AOR 2.8, 95% CI (1.35-5.85)] participants. Two-hundred twenty-one [36%] participants had comorbidity in their household with hypertension, 72 [11.7%], diabetes,50 [8.1%], asthma, 48 [7.8%], and other chronic diseases, 51 [8.4%]. Forty-six [7.5%] participants had COVID-like symptoms in the previous month, where cough, headache, and fatigue were the most common. Conclusion: COVID-19 posed serious economic pressure on households. Self-employed and unemployed were the most affected. Continuous surveillance is needed to actively monitor the impact of COVID-19 in the community and safeguard the economic and health well-being of individuals and households.

Impact of COVID -19 on population health and economic wellbeing in Ethiopia: A national pilot survey

Introduction: The COVD-19 pandemic has resulted in unprecedented global health and economic crisis, particu-larly in countries struggling with poverty. We conducted a national survey to understand the economic and health impacts of COVID-19 in Ethiopia. Methods: A pilot, population-based, cross-sectional survey was conducted among adults randomly selected from the Ethio Telecom list of mobile phone numbers. Participants underwent a comprehensive phone interview about the impact of COVID-19 on their economic well-being and the health-related risks associated with COVID-19. Results: Of 4,180 calls attempted, 1194 were answered, of which a successful interview was made with 614 par-ticipants. COVID-19 affected the family income of 343 [55.9%] participants, 56 [9.1%] lost their job, 105 [17.1%] perceived high stress in their household, and 7 [1.14%] reported death in their family in the past month. The odds of having a decreased income due to COVID-19 were 2.4 times higher among self-employed [adjusted odds ratio (AOR) 2.4, 95% CI (1.58-3.77)] and 2.8 times higher among unemployed [AOR 2.8, 95% CI (1.35-5.85)] participants.

Determinants of asthma in Ethiopia: age and sex matched case control study with special reference to household fuel exposure and housing characteristics.

BACKGROUND: Asthma is a chronic inflammatory disorder characterized by airway obstruction and hyper-responsiveness. Studies suggest that household fuel exposure and housing characteristics are associated with air way related allergy. But there remains to be a considerable uncertainty about whether that reflects an association with asthma. This study endeavored to bridge the gap by identifying factors associated with asthma, with special reference to household fuel exposure and housing characteristics in selected public hospitals in Addis Ababa, Ethiopia. METHODS: We conducted a hospital-based matched case-control study. A total of 483 study participants were selected from two Ethiopian referral hospitals using a sequential sampling technique, with 161 cases and 322 controls. Standard questionnaire from the European Community Respiratory Health Survey II (ECRHS II) and the American Thoracic Society Division of Lung Disease (ATS-DLD-78) were used to collect household related data. Conditional logistic regression model was applied to identify the determinants of asthma. Both crude and adjusted odds ratios with 95% confidence interval (CI) were used to identify predictors of asthma. RESULTS: The response rate for both cases and controls was 99.17%. The odds of developing asthma was about four times higher among those who used agricultural residues for cooking (AOR: 3.81, 95% CI: 1.05, 13.79)., about five times higher among those who used wood for cooking (AOR: 4.95, 95% CI: 2.1, 11.69), nearly five times higher among those who had family history of asthma (AOR: 4.72, 95% CI: 1.54, 14.45), just over six times higher among those who smoke tobacco (AOR: 6.16, 95% CI: 1.31, 29.09) and over ten times higher among those who do not practice door opening, while cooking (AOR: 10.25, 95% CI: 3.97, 26.49). CONCLUSION: Family history of asthma, tobacco smoking, use of solid fuels including, woods and agricultural residues were associated with development of asthma. To reduce the risk of asthma, people should practice door opening, while cooking, and must avoid using wood and agricultural residues for cooking and should also refrain from tobacco smoking.

Prognostic factors and outcomes of COVID-19 cases in Ethiopia: multi-center cohort study protocol.

BACKGROUND: The coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2) and became pandemic after emerging in Wuhan, China, in December 2019. Several studies have been conducted to understand the key features of COVID-19 and its public health impact. However, the prognostic factors of COVID-19 are not well studied in the African setting. In this study, we aim to determine the epidemiological and clinical features of COVID-19 cases, immunological and virological courses, interaction with nutritional status, and response to treatment for COVID-19 patients in Ethiopia. METHODS: A multi-center cohort study design will be performed. Patients with confirmed COVID-19 infection admitted to selected treatment centers will be enrolled irrespective of their symptoms and followed-up for 12 months. Baseline epidemiological, clinical, laboratory and imaging data will be collected from treatment records, interviews, physical measurements, and biological samples. Follow-up data collection involves treatment and prognostic outcomes to be measured using different biomarkers and clinical parameters. Data collection will be done electronically using the Open Data Kit (ODK) software package and then exported to STATA/SPSS for analysis. Both descriptive and multivariable analyses will be performed to assess the independent determinants of the treatment outcome and prognosis to generate relevant information for informed prevention and case management. The primary outcomes of this study are death/survival and viral shedding. Secondary outcomes include epidemiological characteristics, clinical features, genetic frequency shifts (genotypic variations), and nutritional status. DISCUSSION: This is the first large prospective cohort study of patients in hospitals with COVID-19 in Ethiopia. The results will enable us to better understand the epidemiology of SARS-CoV-2 in Africa. This study will also provide useful information for effective public health measures and future pandemic preparedness and in response to outbreaks. It will also support policymakers in managing the epidemic based on scientific evidence. TRIAL REGISTRATION: The Protocol prospectively registered in ClinicalTrials.gov (NCT04584424) on 30 October, 2020.

Trends of follow-up clinic visits and admissions three-months before and during COVID-19 pandemic at Tikur Anbessa specialized hospital, Addis Ababa, Ethiopia: an interrupted time series analysis.

BACKGROUND: Following the first report of the COVID-19 case in Ethiopia on March 13, 2020, the country promptly adopted a lockdown policy to contain the virus's spread. Responding to the healthcare burden imposed by the COVID-19 pandemic had to be coupled with ensuring essential health care services. This study assessed the impact of COVID-19 on the trends in hospital visits and admissions at Tikur Anbessa Specialized Hospital by comparing the rate of follow-up clinic visits and admissions for the 3 months before and after the first report of the COVID-19 case. METHODS: A retrospective, time-series study examined the trend in follow-up visits and admissions between December 11, 2019, to June 7, 2020, with the 1st case of the COVID-19 report in Ethiopia (March 13, 2020) as a reference time. To control seasonal effects and random fluctuation, we have compared health care utilization to its equivalent period in 2018/19. A data extraction tool was used to collect secondary data from each unit's electronic medical recordings and logbooks. RESULTS: A total of 7717 visits from eight follow-up clinics and 3310 admissions were collected 3 months before the onset of COVID-19. During the following 3 months after the onset of the pandemic, 4597 visits and 2383 admissions were collected. Overall, a 40.4% decrease in follow-up visits and a 28% decline in admissions were observed during the COVID-19 pandemic. A drop in the daily follow-up visits was observed for both genders. The number of visits in all follow-up clinics in 2019/2020 decreased compared to the same months in 2018/19 (p < 0.05). Follow-up visits were substantially lower for renal patients (- 68%), patients with neurologic problems (- 53.9%), antiretroviral treatment clinics (- 52.3%), cardiac patients (- 51.4%). Although pediatric emergency admission was significantly lower (- 54.1%) from the baseline (p = 0.04), admissions from the general pediatric and adult wards did not show a significant difference. CONCLUSIONS: A decline in follow-up clinic visits and emergency admissions was observed during the first months of the COVID-19 pandemic. This will increase the possibility of avoidable morbidity and mortality due to non-COVID-19-related illnesses. Further studies are needed to explore the reasons for the decline and track the pandemic's long-term effects among non-COVID-19 patients.

Evaluation of COVID-19 related knowledge and preparedness in health professionals at selected health facilities in a resource-limited setting in Addis Ababa, Ethiopia.

BACKGROUND: The World Health Organization has declared that infection with SARS-CoV-2 is a pandemic. Experiences with SARS in 2003 and SARS-CoV-2 have shown that health professionals are at higher risk of contracting COVID-19. Hence, it has been recommended that aperiodic wide-scale assessment of the knowledge and preparedness of health professionals regarding the current COVID-19 pandemic is critical. OBJECTIVES: This study aimed to assess the knowledge and preparedness of health professionals regarding COVID-19 among selected hospitals in Addis Ababa, Ethiopia. METHODS: A facility-based cross-sectional study was conducted from the last week of March to early April, 2020. Government (n = 6) and private hospitals (n = 4) were included. The front-line participants with high exposure were proportionally recruited from their departments. The collected data from a self-administered questionnaire were entered using EpiData and analyzed in SPSS software. Both descriptive statistics and inferential statistics (chi-square tests) are presented. RESULTS: A total of 1334 health professionals participated in the study. The majority (675, 50.7%) of the participants were female. Of the total, 532 (39.9%) subjects were nurses/midwives, followed by doctors (397, 29.8%) and pharmacists (193, 14.5%). Of these, one-third had received formal training on COVID-19. The mean knowledge score of participants was 16.45 (±4.4). Regarding knowledge about COVID-19, 783 (58.7%), 354 (26.5%), and 196 (14.7%) participants had moderate, good, and poor knowledge, respectively. Lower scores were seen in younger age groups, females, and non-physicians. Two-thirds (63.2%) of the subjects responded that they had been updated by their hospital on COVID-19. Of the total, 1020 (76.5%) participants responded that television, radio, and newspapers were their primary sources of information. Established hospital preparedness measures were confirmed by 43-57% of participants. CONCLUSION: The current study revealed that health professionals in Addis Ababa, Ethiopia, already know important facts but had moderate overall knowledge about the COVID-19 pandemic. There were unmet needs in younger age groups, non-physicians, and females. Half of the respondents mentioning inadequate preparedness of their hospitals point to the need for more global solidarity, especially concerning the shortage of consumables and lack of equipment.

Pragmatic Recommendations for the Management of Anticoagulation and Venous Thrombotic Disease for Hospitalized Patients with COVID-19 in Low- and Middle-Income Countries.

New studies of COVID-19 are constantly updating best practices in clinical care. Often, it is impractical to apply recommendations based on high-income country investigations to resource limited settings in low- and middle-income countries (LMICs). We present a set of pragmatic recommendations for the management of anticoagulation and thrombotic disease for hospitalized patients with COVID-19 in LMICs. In the absence of contraindications, we recommend prophylactic anticoagulation with either low molecular weight heparin (LMWH) or unfractionated heparin (UFH) for all hospitalized COVID-19 patients in LMICs. If available, we recommend LMWH over UFH for venous thromboembolism (VTE) prophylaxis to minimize risk to healthcare workers. We recommend against the use of aspirin for VTE prophylaxis in hospitalized COVID-19 and non-COVID-19 patients in LMICs. Because of limited evidence, we suggest against the use of "enhanced" or "intermediate" prophylaxis in COVID-19 patients in LMICs. Based on current available evidence, we recommend against the initiation of empiric therapeutic anticoagulation without clinical suspicion for VTE. If contraindications exist to chemical prophylaxis, we recommend mechanical prophylaxis with intermittent pneumatic compression (IPC) devices or graduated compression stockings (GCS) for hospitalized COVID-19 patients in LMICs. In LMICs, we recommend initiating therapeutic anticoagulation for hospitalized COVID-19 patients, in accordance with local clinical practice guidelines, if there is high clinical suspicion for VTE, even in the absence of testing. If available, we recommend LMWH over UFH or Direct oral anticoagulants for treatment of VTE in LMICs to minimize risk to healthcare workers. In LMIC settings where continuous intravenous UFH or LMWH are unavailable or not feasible to use, we recommend fixed dose heparin, adjusted to body weight, in hospitalized COVID-19 patients with high clinical suspicion of VTE. We suggest D-dimer measurement, if available and affordable, at the time of admission for risk stratification, or when clinical suspicion for VTE is high. For hospitalized COVID-19 patients in LMICs, based on current available evidence, we make no recommendation on the use of serial D-dimer monitoring for the initiation of therapeutic anticoagulation. For hospitalized COVID-19 patients in LMICs receiving intravenous therapeutic UFH, we recommend serial monitoring of partial thromboplastin time or anti-factor Xa level, based on local laboratory capabilities. For hospitalized COVID-19 patients in LMICs receiving LMWH, we suggest against serial monitoring of anti-factor Xa level. We suggest serial monitoring of platelet counts in patients receiving therapeutic anticoagulation for VTE, to assess risk of bleeding or development of heparin induced thrombocytopenia.

COVID-19 and the public response: Knowledge, attitude and practice of the public in mitigating the pandemic in Addis Ababa, Ethiopia.

BACKGROUND: The COVID-19 pandemic is impacting the global community in many ways. Combating the COVID-19 pandemic requires a coordinated effort through engaging public and service providers in preventive measures. The government of Ethiopia had already announced prevention guidelines for the public. However, there is a scarcity of evidence-based data on the public knowledge, attitude, and practice (KAP) and response of the service providers regarding COVID-19. OBJECTIVE: This study aimed to assess the public KAP and service providers' preparedness towards the pandemic in Addis Ababa, Ethiopia. METHODS: A community-based cross-sectional study was conducted in Addis Ababa, Ethiopia, from late March to the first week of April 2020. Participants were conveniently sampled from 10 different city sites. Data collection was performed using a self-administered questionnaire and observational assessment using a checklist. All statistical analysis was performed using SPSS version Descriptive statistics, correlation coefficient and chi-square tests were performed. RESULT: A total of 839 public participants and 420 service providers enrolled in the study. The mean age was 30.30 (range = 18-72) years. The majority of the respondents (58.6%) had moderate knowledge about COVID-19, whereas 37.2% had good knowledge. Moreover, 60.7% and 59.8% of the participants had a positive attitude towards preventive measures and good practice to mitigate the pandemic, respectively. There was a moderate positive correlation between knowledge and attitude, whereas the correlations between knowledge and practice and attitude and practice were weak. With regard to service providers' preparedness, 70% have made hand-washing facilities available. A large majority of the respondents (84.4%) were using government-owned media followed by social media (46.0%) as a main source of information. CONCLUSION: The public in Addis Ababa had moderate knowledge, an optimistic attitude and descent practice. The information flow from government and social media seemed successful seeing the majority of the respondents identifying preventive measures, signs and symptoms and transmission route of SARS-CoV-2. Knowledge and attitude was not associated with practice, thus, additional innovative strategies for practice changes are needed. Two thirds of the service provider made available hand washing facilities which seems a first positive step. However, periodic evaluation of the public KAP and assessment of service providers' preparedness is mandatory to combat the pandemic effectively.

Burden of tuberculosis and challenges related to screening and diagnosis in Ethiopia.

INTRODUCTION: One-third of tuberculosis (TB) cases in Ethiopia are missing from care for reasons that are not well studied. The aim of this study was to assess TB burden and identify challenges related to TB screening and diagnosis in Ethiopia. METHODS: A facility-based cross-sectional study was conducted in seven health facilities selected from two regions and 2 city administrations of Ethiopia using stratified random sampling procedures. The data of 1,059,065 patients were included from outpatient department, HIV clinic, diabetic, and maternal-child health clinics. Data were collected from October to December 2018 using a retrospective review of three years' facility data (2015 to 2017) supplemented by a semi-structured interview with purposively selected health care workers and heads of the health facilities. RESULTS: A total of 1,059,065 patients visited the health facilities in three years, of these, 978,480 (92.4%) were outpatients. Of the total, 20,284 (2%) were presumptive TB cases (with 14 days or more cough), 12.2% (2483/20,284) of which had TB. For the type of TB, 604 (24.3%) were smear-positive pulmonary TB (PTB), 789 (31.8%) were smear-negative PTB, 719 (29%) were extra-pulmonary TB, and data were missing for the rest. TB screening was integrated into HIV clinic, outpatient department, diabetic clinic but not with the maternal and child clinics. High patient load, weak TB laboratory specimen referral system, and shortage of TB diagnostic tools including Xpert MTB/RIF assay and chest X-ray, were the major challenges in the screening and diagnosis of TB. CONCLUSION: The burden of TB was high in the study setting, and frequent interruption of laboratory reagents and supplies hampered TB screening and diagnostic services. Realizing the END-TB strategy in such resource-limited settings requires sustainable TB diagnostic capacity and improved case detection mechanisms, with national TB programs strongly integrated into the general health care system.

Phenotypic characteristics and asthma severity in an East African cohort of adults and adolescents with asthma: findings from the African severe asthma project.

RATIONALE: The relationship between clinical and biomarker characteristics of asthma and its severity in Africa is not well known. METHODS: Using the Expert Panel Report 3, we assessed for asthma severity and its relationship with key phenotypic characteristics in Uganda, Kenya and Ethiopia. The characteristics included adult onset asthma, family history of asthma, exposures (smoking and biomass), comorbidities (HIV, hypertension, obesity, tuberculosis (TB), rhinosinusitis, gastro-oesophageal disease (GERD) and biomarkers (fractional exhaled nitric oxide (FeNO), skin prick test (SPT) and blood eosinophils). We compared these characteristics on the basis of severity and fitted a multivariable logistic regression model to assess the independent association of these characteristics with asthma severity. RESULTS: A total of 1671 patients were enrolled, 70.7% women, with median age of 40 years. The prevalence of intermittent, mild persistent, moderate persistent and severe persistent asthma was 2.9%, 19.9%, 42.6% and 34.6%, respectively. Only 14% were on inhaled corticosteroids (ICS). Patients with severe persistent asthma had a higher rate of adult onset asthma, smoking, HIV, history of TB, FeNO and absolute eosinophil count but lower rates of GERD, rhinosinusitis and SPT positivity. In the multivariate model, Ethiopian site and a history of GERD remained associated with asthma severity. DISCUSSION: The majority of patients in this cohort presented with moderate to severe persistent asthma and the use of ICS was very low. Improving access to ICS and other inhaled therapies could greatly reduce asthma morbidity in Africa.

Desire for birth spacing or limiting and non-use of long acting and permanent contraceptive methods among married women of reproductive age in Aksum Town, North Ethiopia.

BACKGROUND: Long acting and permanent contraceptive methods are the most effective family planning (FP) methods to prevent pregnancy and thereby averting adverse consequences of too many and ill-timed pregnancies. However, long acting and permanent contraceptive methods (LAPMs) are underutilized in Ethiopia for little documented reasons. Therefore, this study is aimed to assess magnitude and factors associated with desire for birth spacing for at least 2 years or limiting child bearing and non-use of LAPMs among married women of reproductive age in Aksum town, Northern Ethiopia. METHODS: A community-based cross-sectional study was conducted in Aksum town, North Ethiopia from May to June, 2015 among 779 randomly selected married women of reproductive age. Data were collected using interviewer administered pre-tested questionnaire. Data were entered using Epi-Info version 6.04 and exported to SPSS version 16 for analysis. Multivariate logistic regression models were fitted to identify factors associated with desire for birth spacing or limiting and not using LAPMs. RESULTS: The total desire for birth spacing or limiting was 69 % and amongst those women 85.2 % were not using LAPM. Education, occupation, husband's attitude towards LAPMs, age, number of pregnancy, regular media exposure and decider on the number of children to bear were significantly associated with desire for birth spacing or limiting. Moreover; education, occupation, husband's attitude towards LAPMs, discussion on family planning with husband, knowledge, attitude and intention to use LAPMs were significantly associated with not using LAPMs. CONCLUSION: Desire for birth spacing or limiting and not using LAPMs is very high in the study area. Therefore, increasing access to family planning information and services with special emphasis on LAPMs and male involvement in the program are very important.

Population-based prevalence survey of tuberculosis in the Tigray region of Ethiopia.

BACKGROUND: Population based prevalence survey is an important epidemiological index to measure the burden of tuberculosis (TB) disease and monitor progress towards TB control in high burden countries like Ethiopia. This study was aimed to estimate the prevalence of bacteriologically confirmed pulmonary tuberculosis (PTB) in the Tigray region of Ethiopia. METHODS: Sixteen rural and urban villages were randomly selected in a stratified multistage cluster sampling. Individuals aged 15 years and older were screened by symptom inquiry for PTB. Those individuals who were symptomatic of PTB provided two sputum samples for smear microscopy, culture and molecular typing. RESULTS: The study covering 4,765 households screened a total of 12,175 individuals aged 15 years and above. The overall weighted prevalence of bacteriologically confirmed PTB in the Tigray region of Ethiopia was found to be 216/100,000 (95% CI: 202.08, 230.76) while the weighted prevalence of smear-positive PTB was 169/100,000 (95% CI: 155.53, 181.60). The prevalence of bacteriologically confirmed TB was higher amongst males (352/100 000; 95% CI: 339.05, 364.52) than females (162/100 000; 95% CI: 153.60, 171.17) and among rural (222/100,000; 95% CI: 212.77-231.53) as compared to urban residents (193/100,000; 95% CI: 183.39-203.59). CONCLUSIONS: This study found a relatively higher prevalence smear-positive PTB in the region than in a same period nationwide survey and identified a significant number of undetected PTB cases. The urgency for improved TB case detection and intensified community awareness is emphasized.

An epidemiological study into the investigation of liver disease of unknown origin in a rural community of northern Ethiopia, 2005.

BACKGROUND: An outbreak of an unidentified cause of liver disease that claimed the lives of more than 45 people occurred in a rural community, in Northwestern Tigray. Despite the wider need for an urgent response there was no obvious explanation for the disease occurrence. OBJECTIVE: The aim of the study was to collect basic descriptive information and compare exposure status among case and control house-holds to better understand the illness and its pattern of occurrence so as to identify the sources, mode of transmission and possible cause of the illness. METHODS: The initial study principally involved combination of descriptive and analytic study designs. Combinations of quantitative and qualitative data were collected using semi-structured questionnaires. STUDY SUBJECTS: Samples of the affected and non-affected individuals of study village, key informants from various levels in the administrative system, and focus group discussions organized from both the affected and non-affected households of the study village were the subjects included for the study. RESULTS: The outbreak involved about 118 people, (78 males and 40 females) who were residents of the same village, in most, members of same family. More than half of the cases were under the age of 15 years. The outstanding clinical features were abdominal pain, rapidly filling ascites and hepatomegaly. The median duration of illness was six months (range; 1, 36 months). Of the 118 cases, 45 were deaths reported from the same community, during the period of illness with an estimated case fatality rate of 38%. Of the 45 deaths, 64.4% were children below 15 years of age. Qualitative information from both case and control communities showed difference in their water source. Eighty four percent of the dwellers in the affected village of Tsaeda Amba fetch water for their drink from an open shallow unprotected pond, Mai Habi-Tselam, Analysis of the data on exposure to the risk factor (case--control house-holds) revealed that users of the Habi-Tselam water source were almost 3 times more likely to develop the liver disease than those who used other water sources in the same village, OR = 3.14, 95% CI: 3.14 (3.12, 3.23). Age, nutritional status and long duration of exposure to an implicated source tended to influence the prognosis. CONCLUSION: The initial epidemiological investigations therefore gave an important insight as to the need to conduct further possible in-depth etiologic investigations, including clinical and toxicological studies, Study recommended an intermediary control measures including: banning the use of the implicated water source and provision of save and alternative potable water to the affected community.

An outbreak of veno-occlusive liver disease in northern Ethiopia, clinical findings.

BACKGROUND: Following the emergence of an unidentified fatal disease in Tahtay Koraro, rural farmers' village in Tigray, northern Ethiopia since 2001, a team of experts from Addis Ababa University Medical Faculty was assigned in November 2005, to investigate the problem in the field. The team consisted of an Infectious disease specialist, a Gastroenterologist, an Epidemiologist, a Pathologist, and a Microbiologist. The team was also joined by a group of Tigray Regional Health Bureauprofessionals. OBJECTIVES: To investigate the nature of unidentified liver disease, identify possible cause(s) and recommend specific interventions/treatment in order to save lives and stop further spread of the disease. METHODS: Data were collected from Clinical history, clinical evaluation of the affected cases in the area, relevant laboratory investigations, and histopathologic studies. RESULTS: The team evaluated sixty one of patients in the field (37 males and 24 females) with mean age of 27 years. The disease affected both gender and all age groups. Duration of the illness ranged from 1 month to 3 years with a median of 6 months. The illness was reported to have started with abdominal cramp in 75%, febrile syndrome in 77%, and abdominal distention in 63% of the cases. This was usually followed by jaundice, bleeding tendencies, and edematous states mainly in the form of rapidly filling ascites. Majority of the patients had similarly sick family members and/or lost family member(s) due to the same illness. Moreover, laboratory, sonography, histopathological, and toxicological studies revealed VOLD due to Pyrrolizidine alkaloid (PA) toxicity as described in the other sections of the supplement. CONCLUSION: From a detailed clinical and epidemiological investigation as well as histopathological and toxicological analyses, the disease was found to be fatal toxic hepatitis (veno-occlusive liver disease (VOLD). To our knowledge, this is the first report of VOLD from Ethiopia.

Veno-occlusive liver disease: a case report.

A case of veno-occlusive liver disease (VOLD) in a 12-years old Ethiopian boy is described The salient clinical features and gross and microscopic examination of biopsy material are reviewed. Veno-occlusive disease which occurs in the West Indies, East and West Africa, and India is an acute, subacute or chronic condition that affects the central and sublobular hepatic veins. In the West Indies (1) it is related to the consumption of bush tea made from plants that contain toxic pyrrolizidine alkaloids, such as Crotalaria and Senecio (2). Hepatotoxic compounds in Crotalaria, Senecio, Heliotropium and other composite plants can also enter the diet through the contamination of cereals with weed seeds. For example 28 of 67 patients died with veno-occlusive disease in central India after consuming a local cereal, gondli contaminated with the seeds of Crotalaria (3). Heliotropium Popovii has been implicated in outbreaks in villages in northwestern Afghanistan, with high mortality (4). The primary pathological change of hepatic veno-occlusive disease is sub-endothelial edema followed by intimal growth of connective tissue, with narrowing and occlusion of the central and sub-lobular hepatic veins. Atrophy or necrosis of liver cells, with consequent fibrosis leads to gross changes similar to those seen in cardiac cirrhosis, portal hypertension results. The present report, the first of it kind in Ethiopia describes a case of veno-occlusive liver disease in a 12-year old Ethiopian boy.
