Disclosure History Among Persons Initiating Antiretroviral Treatment at Six HIV Clinics in Oromia,Ethiopia, 2012–2013

HIV status disclosure can help patients obtain support which may influence treatment adherence and subsequent healthcare needs. We examined the extent of disclosure and correlates of non-disclosure among 1180 adults newly initiating antiretroviral treatment (ART). While 91 % of those in a relationship shared their status with their partners, 14 % of the overall sample had not disclosed to anyone. Non-disclosure was positively associated with older age; control over household resources; and concerns about unintended disclosure, life disruptions, and family reactions. Knowing other HIV-positive people and longer time since diagnosis were associated with lower odds of non-disclosure. Most respondents reporting disclosure experienced supportive responses, frequently including decision to get an HIV test by confidants who had not known their own status. Although HIV status disclosure prior to ART initiation was high, some individuals cited concerns about unintended disclosure, gossip, and partner violence, and may benefit from additional disclosure support.     

Seroprevalence of cysticercosis in Bénin.

We report the results of a seroepidemiological study on the prevalence of cysticercosis in Bénin. Cluster sampling at 3 levels was performed in the 6 départements (Atacora, Borgou, Zou, Mono, Atlantique and Oueme) and 2625 serum samples, from 1329 adult females and 1296 adult males, were collected. Antibodies against Taenia solium cysticerci were first searched for by enzyme-linked immunosorbent assay and the 41 seropositive samples were then examined by enzyme-linked electroimmunotransfer blot assay (EITB). Thirty-five samples gave positive results in the EITB. The overall seroprevalence of cysticercosis was therefore 1.3% (95% confidence interval [95% CI] 0.9-1.9). The seroprevalence was 1.9% in males (95% CI 1.2-2.7) and 0.8% (95% CI 0.4-1.5) in females (P < 0.05). A progressive increase in seroprevalence with increasing age was found. The highest seroprevalences were observed in Atacora and Atlantique, 2 non-Muslim départements (3.3% and 3.0%, respectively). This study demonstrated the public health importance of cysticercosis in Bénin.     

National disability-adjusted life years (DALYs) for 257 diseases and injuries in Ethiopia, 1990–2015: findings from the global burden of disease study 2015

Background

Disability-adjusted life years (DALYs) provide a summary measure of health and can be a critical input to guide health systems, investments, and priority-setting in Ethiopia. We aimed to determine the leading causes of premature mortality and disability using DALYs and describe the relative burden of disease and injuries in Ethiopia.

Methods

We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 (GBD 2015) for non-fatal disease burden, cause-specific mortality, and all-cause mortality to derive age-standardized DALYs by sex for Ethiopia for each year. We calculated DALYs by summing years of life lost due to premature mortality (YLLs) and years lived with disability (YLDs) for each age group and sex. Causes of death by age, sex, and year were measured mainly using Causes of Death Ensemble modeling. To estimate YLDs, a Bayesian meta-regression method was used. We reported DALY rates per 100,000 for communicable, maternal, neonatal, and nutritional (CMNN) disorders, non-communicable diseases, and injuries, with 95% uncertainty intervals (UI) for Ethiopia.

Results

Non-communicable diseases caused 23,118.1 (95% UI, 17,124.4–30,579.6), CMNN disorders resulted in 20,200.7 (95% UI, 16,532.2–24,917.9), and injuries caused 3781 (95% UI, 2642.9–5500.6) age-standardized DALYs per 100,000 in Ethiopia in 2015. Lower respiratory infections, diarrheal diseases, and tuberculosis were the top three leading causes of DALYs in 2015, accounting for 2998 (95% UI, 2173.7–4029), 2592.5 (95% UI, 1850.7–3495.1), and 2562.9 (95% UI, 1466.1–4220.7) DALYs per 100,000, respectively. Ischemic heart disease and cerebrovascular disease were the fourth and fifth leading causes of age-standardized DALYs, with rates of 2535.7 (95% UI, 1603.7–3843.2) and 2159.9 (95% UI, 1369.7–3216.3) per 100,000, respectively. The following causes showed a reduction of 60% or more over the last 25 years: lower respiratory infections, diarrheal diseases, tuberculosis, neonatal encephalopathy, preterm birth complications, meningitis, malaria, protein-energy malnutrition, iron-deficiency anemia, measles, war and legal intervention, and maternal hemorrhage.

Conclusions

Ethiopia has been successful in reducing age-standardized DALYs related to most communicable, maternal, neonatal, and nutritional deficiency diseases in the last 25 years, causing a major ranking shift to types of non-communicable disease. Lower respiratory infections, diarrheal disease, and tuberculosis continue to be leading causes of premature death, despite major declines in burden. Non-communicable diseases also showed reductions as premature mortality declined; however, disability outcomes for these causes did not show declines. Recently developed non-communicable disease strategies may need to be amended to focus on cardiovascular diseases, cancer, diabetes, and major depressive disorders. Increasing trends of disabilities due to neonatal encephalopathy, preterm birth complications, and neonatal disorders should be emphasized in the national newborn survival strategy. Generating quality data should be a priority through the development of new initiatives such as vital events registration, surveillance programs, and surveys to address gaps in data. Measuring disease burden at subnational regional state levels and identifying variations with urban and rural population health should be conducted to support health policy in Ethiopia.

     

Geographic Distribution of MERS Coronavirus among Dromedary Camels,Africa

We found serologic evidence for the circulation of Middle East respiratory syndrome coronavirus among dromedary camels in Nigeria, Tunisia, and Ethiopia. Circulation of the virus among dromedaries across broad areas of Africa may indicate that this disease is currently underdiagnosed in humans outside the Arabian Peninsula.     

Evidence of genetic variability of human immunodeficiency virus type 1 in plasma and cervicovaginal lavage in ethiopian women seeking care for sexually transmitted infections

Most human immunodeficiency virus type 1 (HIV-1) transmission in developing countries occurs through heterosexual intercourse or during birth from mother to child. It is critical to characterize the virus of the genital tract variants as a target for the development of an HIV-1 vaccine and microbicidal therapies. We compared the C2V3 env domain genetic diversity of HIV-1 in female genital secretions and in plasma from Ethiopian women seeking care for sexually transmitted infections (STIs). Sequences within an individual differed between the plasma and cervicovaginal lavage (CLV) compartments with nucleotide and amino acid median difference values of 8.3 and 4.8%, respectively. Sequence diversity in CVL was greater than in plasma. And the V3 loop positive charge was often more elevated in CVL. These are markers of the differential evolution of the viruses in CVL and peripheral blood indicating that limited evolution at the site of contact is not the limiting factor determining the preferential transmission of macrophage tropic viruses.     

Demographic and Health-related Risk Factors of Subclinical Vitamin A Deficiency in Ethiopia

The study was conducted to determine the demographic and health-related risk factors of subclinical vitamin A deficiency in Ethiopia. Blood samples were collected from 996 children in 210 clusters across the nation for analysis of serum retinol. Interviews were conducted with the respective mothers of the 996 children on presumed risk factors of vitamin A deficiency. A higher subclinical vitamin A deficiency was associated with: not receiving vitamin A supplement over the year, having been ill during the two weeks preceding the survey, no or incomplete vaccination, belonging to a mother with high parity, and low levels of awareness of vitamin A. Moreover, being from Muslim household was strongly associated with higher levels of subclinical vitamin A deficiency. Among the risk factors identified, low levels of vaccination, high parity, and low levels of maternal awareness of vitamin A contributed to higher risks of vitamin A deficiency among Muslim children. The findings underscore the need for creation of strengthened awareness of family planning and importance of vitamin A, promotion of vaccination and child health, intensification of vitamin A supplementation, and in-depth investigation on factors contributing to increased vulnerability of Muslim children.Key words: Cross-sectional studies, Risk factors, Serum retinol, Vitamin A, Vitamin A deficiency, Xerophthalmia, Ethiopia     

Content of zinc, iron, calcium and their absorption inhibitors in foods commonly consumed in Ethiopia

The zinc, iron, calcium, phosphorus, phytate, tannin and moisture content of 36 foods consumed in rural Ethiopia were analysed. The foods analysed included those based on cereals, starchy tubers and roots, and legumes and vegetables as well as some fruits. Although many foods were relatively rich in zinc and iron, many also contained high levels of phytic acid and tannins, which impair bioavailability of zinc and iron. The phytate:zinc molar ratios were >20 for non-fermented cereal foods, >15 for legumes, and <12 for fermented cereals, starchy tubers and roots. Ratios >15 are associated with low bioavailability of zinc. Given the high iron content and the relatively favourable phytate:iron molar ratio, tef enjera was the best source of bioavailable iron of all foods analysed. Foods prepared from tef, enset and kale are rich sources of calcium. The consumption of diets based on cereals and legumes but poor in animal products can lead to deficiencies of zinc and iron. However, since fermentation can decrease the phytate content by a factor of 3–4, traditional household practices such as fermentation need to be encouraged to address the problem of zinc deficiency, which is particularly prevalent in Ethiopia.
