Anemia and risk factors in HAART naive and HAART experienced HIV positive persons in south west Ethiopia: a comparative study.

ABSTRACT: BACKGROUND: Human immunodeficiency virus (HIV) infection and its treatment cause a range of hematological abnormalities. Anemia is one of the commonly observed hematologic manifestations in HIV positive persons and it has multifactorial origin. OBJECTIVE: We aimed to determine the prevalence and risk factors of anemia in highly active antiretroviral therapy (HAART) naïve and HAART experienced HIV positive persons. METHODS: A facility-based comparative cross sectional study was conducted in Jimma University Specialized Hospital from February 1 to March 30, 2012. A total of 234 HIV positive persons, 117 HAART naïve and 117 HAART experienced, were enrolled in this study. Blood and stool specimens were collected from each participant. Blood specimens were examined for complete blood count, CD4 count and blood film for malaria hemoparasite; whereas stool specimens were checked for ova of intestinal parasites. Socio-demographic characteristics and clinical data of the participants were collected using pre-tested questionnaire. Statistical analysis of the data (Chi-square, student's t-test, logistic regression) was done using SPSS V-16. RESULTS: The overall prevalence of anemia was 23.1%. The prevalence of anemia in HAART naïve and HAART experienced persons was 29.9% and 16.2%, respectively (P = 0.014). Presence of opportunistic infections (P = 0.004, 95% CI = 1.69-15.46), CD4 count <200 cells/µl (P = 0.001, 95% CI = 2.57-36.89) and rural residence (P = 0.03, 95% CI = 1.12-10.39) were found to be predictors of anemia for HAART naïve participants. On the other hand, HAART regimen (ZDV/3TC/NVP) (P = 0.019, 95% CI = 0.01-1.24) and the duration of HAART (P = 0.007, 95% CI = 0.003-0.40.24) were found to be predictors of anemia for HAART experienced groups. CONCLUSION: The prevalence of anemia in HAART naïve persons was higher than HAART experienced persons. Risk factors for anemia in HAART naïve and HAART experienced HIV positive persons were different. Hence, there is a need for longitudinal study to further explore the causes of HIV associated anemia and the pattern of hemoglobin changes with initiation of HAART.

Project description:BackgroundAnemia is the most common hematologic abnormalities in AIDS patients usually associated with disease progression and poor clinical outcomes. Zidovudine (AZT), which is one of the nucleoside reverse transcriptase inhibitor drug families of the first line antiretroviral therapy regimen for HIV/AIDS patients, causes anemia due to early long-term of higher-dose therapy. This study was aimed to assess the magnitude and associated factors of anemia among AZT containing HAART experienced adult HIV/ADIS patients at University of Gondar Comprehensive Specialized Referral Hospital, northwest, Ethiopia, 2019.MethodsA retrospective cohort study was conducted among a total of 320 adult AZT based HAART experienced HIV/AIDS patients from January 2016 to December 2018. Systematic random sampling technique was used to select the patients' charts. All required data for this study were extracted from patients' medical charts. Data were coded, cleared and entered into Epi Info version 3.5.3, and transformed to SPSS version 20 for analysis. Descriptive statistics, bivariable and multivariable logistic regression models were fitted to identify associated factors of anemia and P-value < 0.05 was considered as statistically significance.ResultsA total of 320 adult AZT based HAART experienced HIV/AIDS patients' charts were assessed. Of the total patients, 198 (61.9%) were females and 133 (41.6%) were within the age range of 35-45 years. More than half, 237(76.9%) of the patients were from the urban area and 186 (58.1%) were on WHO clinical stage III at the baseline. The prevalence of anemia was 50% (95% CI 44.7-55.0%), 44.1% (95% CI 38.4-50.0%), 35.6% (95% CI 30.3-40.6%), 40% (95% CI 34.4-45.6%), 40.6% (95% CI 35.0-46.3) and 39.1% (95% CI 33.4-44.1%) at baseline, 6 months, 12 months, 18 months, 24 months and 30 months of follow-up period, respectively. The overall prevalence of anemia was 41.6%. Anemia had significant association with WHO clinical stage and base line Hgb values.ConclusionsA significant number of participants were anemic in this study. WHO clinical stage and baseline Hgb value were the contributing factors for anemia among these patients. Therefore, anemia needs an immediate intervention on associated factor to improve the anemic status and living condition of HIV patient.

Project description:BACKGROUND:Adolescence is characterized by rapid growth and development and iron requirements increase during this time. Adolescents with poor diet in early childhood and/or females with an early onset of menarche may be at greater risk for developing anemia due to the rapid depletion of iron stores in their bodies. OBJECTIVE:The objective of this study was to assess the prevalence and severity of anemia among school adolescents in Wonago district, Gedeo Zone, South Ethiopia. METHODS:A school based cross-sectional study was conducted among 443 randomly selected school adolescents across 15 schools (2 secondary schools and 13 primary schools) in the district. Hemoglobin concentration from a capillary blood sample was determined by portable hemoglobin meter (HemoCue). Descriptive statistics were computed for prevalence of anemia, anthropometric measurements, socio-economic and socio-demographic variables. A hierarchical multivariable logistic regression analysis was done to identify determinants of anemia among adolescents. RESULTS:The prevalence of anemia among adolescents in the study area was 22%. Anemia was higher among those in early adolescence period (10-13 years) (AOR: 4.75, CI: 1.69-13.35) compared to late adolescence (17-19 years) and among those with height for age z-score less than -2 (AOR: 6.23, CI: 1.98-19.62). Similarly, anemia was higher among those in households with a family size greater than five members (AOR: 9.82, CI: 2.42-39.88), adolescents from rural areas (AOR: 4.37, CI: 1.54-12.46) and families who purchase food needed for daily consumption (AOR: 3.25, CI: 1.42-7.45). On the other hand, adolescents from middle wealth quintiles (AOR: 0.26 (CI: 0.07-0.98)) and female adolescents (AOR: 0.34 (CI: 0.15-0.79) were less likely to be anemic in this study. CONCLUSIONS:The prevalence of anemia in this population is of moderate public health concern, adolescents of both sexes are among groups at risk for the development of anemia. The need for further assessment of the etiology of anemia should be considered to design pragmatic intervention programs.

Project description:BackgroundDespite the availability of a highly effective vaccine, yellow fever virus (YFV) remains an important public health problem across Africa and South America due to its high case-fatality rate. This study investigated the historical epidemiology and contemporary entomological and social determinants of a YFV outbreak in South Omo Zone (SOZ), Ethiopia.MethodsA YFV outbreak occurred in SOZ, Ethiopia in 2012-2014. Historical epidemiological data were retrieved from the SOZ Health Department and analyzed. Entomological sampling was undertaken in 2017, including mosquito species identification and molecular screening for arboviruses to understand mosquito habitat distribution, and finally current knowledge, attitudes and preventative practices within the affected communities were assessed.ResultsFrom October 2012 to March 2014, 165 suspected cases and 62 deaths were reported, principally in rural areas of South Ari region (83.6%). The majority of patients were 15-44 years old (75.8%) and most case deaths were males (76%). Between June and August 2017, 688 containers were sampled across 180 households to identify key breeding sites for Aedes mosquitoes. Ensete ventricosum ("false banana") and clay pots outside the home were the most productive natural and artificial breeding sites, respectively. Entomological risk indices classified most sites as "high risk" for future outbreaks under current World Health Organization criteria. Adult mosquitoes in houses were identified as members of the Aedes simpsoni complex but no YFV or other arboviruses were detected by PCR. The majority of community members had heard of YFV, however few activities were undertaken to actively reduce mosquito breeding sites.DiscussionStudy results highlight the potential role vector control could play in mitigating local disease transmission and emphasize the urgent need to strengthen disease surveillance systems and in-country laboratory capacity to facilitate more rapid responses to future YFV outbreaks.

Project description:IntroductionEthiopia has achieved the fourth Millennium Development Goal by reducing under 5 mortality. Nevertheless, there are challenges in reducing maternal and neonatal mortality. The aim of this study was to estimate maternal and neonatal mortality and the socio-economic inequalities of these mortalities in rural south-west Ethiopia.MethodsWe visited and enumerated all households but collected data from those that reported pregnancy and birth outcomes in the last five years in 15 of the 30 rural kebeles in Bonke woreda, Gamo Gofa, south-west Ethiopia. The primary outcomes were maternal and neonatal mortality and a secondary outcome was the rate of institutional delivery.ResultsWe found 11,762 births in 6572 households; 11,536 live and 226 stillbirths. There were 49 maternal deaths; yielding a maternal mortality ratio of 425 per 100,000 live births (95% CI:318-556). The poorest households had greater MMR compared to richest (550 vs 239 per 100,000 live births). However, the socio-economic factors examined did not have statistically significant association with maternal mortality. There were 308 neonatal deaths; resulting in a neonatal mortality ratio of 27 per 1000 live births (95% CI: 24-30). Neonatal mortality was greater in households in the poorest quartile compared to the richest; adjusted OR (AOR): 2.62 (95% CI: 1.65-4.15), headed by illiterates compared to better educated; AOR: 3.54 (95% CI: 1.11-11.30), far from road (?6 km) compared to within 5 km; AOR: 2.40 (95% CI: 1.56-3.69), that had three or more births in five years compared to two or less; AOR: 3.22 (95% CI: 2.45-4.22). Households with maternal mortality had an increased risk of stillbirths; OR: 11.6 (95% CI: 6.00-22.7), and neonatal deaths; OR: 7.2 (95% CI: 3.6-14.3). Institutional delivery was only 3.7%.ConclusionHigh mortality with socio-economic inequality and low institutional delivery highlight the importance of strengthening obstetric interventions in rural south-west Ethiopia.

Project description:BackgroundHuman-wildlife conflict (HWC) is any interaction between humans and wildlife that arises when wildlife necessities encroach on those of the human population. It affects all areas where animal and peoples cohabit regardless of geography or climatic circumstances; but the burden is great in developing nations. De Brazza's monkey (DM) (Cercopithecus neglectus) is one of the most unusual species in the group of Old-World monkeys commonly known as guenons. The De Brazza's monkey is distributed in different parts of African forests from Guinea to Ethiopia. This study was conducted in Kafa Biosphere Reserve, Kafa Zone, South West Ethiopia, to assess the causes of human wildlife conflict in the area. The methods used were, household questionnaire, focus group discussion and direct field observation from June 2022 to May 2023.ResultsThe study revealed that the major causes of human De Brazza's monkey conflicts were; habitat destruction 52.9%, (n = 72), human proximity to natural forest, 25.7%, (n = 35) and increasing of its population size 8.1 %, (n = 11). These monkeys' raids crop usually early in the morning 42.6%, (n = 58), and late evening 29.4%, (n = 40). Maize was the most damaged crop by De Brazza's monkey followed by coffee. The study also confirmed that guarding was the most common method used to protect crops from crop raiding wildlife in the area. Majority 66.2%, (n= 90) of the informants had negative attitude but 22.1%, (n = 30) had positive attitude towards De Brazza's monkey conservation.ConclusionThe study discovered that, in contrast to olive baboons and grivet monkeys in the area, De Brazza's monkeys were not previously identified as crop raiders; however, they are currently causing damage to crops, especially maize and coffee crops. This could be due to habitat destruction and human proximity to the forest boundary. Thus, the conflict between humans and De Brazza's monkeys is escalating. As such, we recommended more research on the population status of the monkeys and strategies for coexist in the area.
