Prevalence of Hepatitis B virus Infection and Associated Risk Factors Among Pregnant Women Attending Antenatal Care Clinics in Kofele Town, Oromia Region, Ethiopia

Hepatitis B virus (HBV) infection is one of the major public health problems affecting many people worldwide. This cross-sectional study was conducted to assess the prevalence and associated factors of HBsAg carriage among pregnant women attending antenatal care clinics in Kofele Town, Oromia Region, Ethiopia from January to April, 2016. A total of 270 pregnant women were recruited using systematic random sampling method. Structured questionnaires were used to collect data on socio-demography and risk factors for HBsAg carriage. Moreover, venous blood samples were collected from all study participants and sera were analyzed for HBsAg marker using SD BIOLINEHBsAg strip test. The prevalence of HBsAg among pregnant women was 5.9%. The age of the women varied from 17–41 years (mean age 24.5 years) and 40.0% were in the age category of 20–24 years. Participants with no formal education (AOR= 6.2; 95% CI= 1.35-28.74, P= 0.019) and had a history of abortion were at higher odds of being HBsAg carrier (AOR= 6.23; 95% CI= 1.74-22.5, P= 0.005). The study showed an intimidate prevalence of HBV infection on the basis of the World Health Organization HBV endemic definition (5-7% HBsAg prevalence). Therefore, screening pregnant women for HBV infection and making the vaccine available to exposed babies need to be emphasized

Helminths and malaria co-infections are associated with elevated serum IgE

BACKGROUND: Both helminth and malaria infections result in a highly polarized immune response characterized by IgE production. This study aimed to investigate the total serum IgE profile in vivo as a measure of Th2 immune response in malaria patients with and without helminth co-infection. METHODS: A cross sectional observational study composed of microscopically confirmed malaria positive (N = 197) and malaria negative (N = 216) apparently healthy controls with and without helminth infection was conducted at Wondo Genet Health Center, Southern Ethiopia. A pre-designed structured format was utilized to collect socio-demographic and clinical data of the subjects. Detection and quantification of helminths, malaria parasites and determination of serum IgE levels were carried out following standard procedures. RESULTS: Irrespective of helminth infection, individuals infected by malaria showed significantly high levels of serum IgE compared with malaria free apparently healthy controls (with and without helminth infections). Moreover, malaria patients co-infected with intestinal helminths showed high level of serum IgE compared with those malaria patients without intestinal helminths (2198 IU/ml versus 1668 IU/ml). A strong statistically significant association was observed between malaria parasite density and elevated serum IgE levels (2047 IU/ml versus 1778 IU/ml; P = 0.001) with high and low parasitaemia (parasite density >50,000 parasite/μl of blood), respectively. Likewise, helminth egg loads were significantly associated with elevated serum IgE levels (P = 0.003). CONCLUSIONS: The elevated serum IgE response in malaria patients irrespective of helminth infection and its correlation with malaria parasite density and helminth egg intensity support that malaria infection is also a strong driver of IgE production as compared to helminths

Human Intestinal Schistosomiasis in Communities Living Near Three Rivers of Jimma Town, South Western Ethiopia

BACKGROUND:Schistosoma mansoni is one of the parasites with high public and medical importance in Ethiopia. However, information is scarce about S. mansoni epidemiology in people living with higher risk of infection in Jimma town. This study was designed to determine point prevalence, intensity and risk factors of S. mansoni infection among residents nearby three rivers of Jimma town and assess the rate of Biomphalaria species shading cercariae from January to April, 2007. METHODS: A cross-sectional study was conducted in communities residing nearby three rivers of Jimma town. Structured questionnaires were used to collect data on socio- demographic and behavioral risk factors. After physical examination, stool samples were collected from 517 study participants and processed with Kato-Katz technique for microscopic examination and quantification of egg load. Snails were collected for identification of Biomphalaria species and then checked for cercarial shading. RESULTS: The prevalence of S. mansoni was 26.3 % with intensity ranging 24 to 936 eggs per gram of stool. Participants in the age group 10-19 years, OR = 2.19 (95% CI; 1.10 – 4.34), and those living near the Awetu River, OR = 2.67 (95% CI; 1.06 – 6.75), had higher risk of S. mansoni infection. Moreover, water contact while crossing a river, OR = 3.77 (95% CI; 1.79 – 7.95), and swimming, OR = 2.59 (95% CI; 1.37 – 4.91, was significantly associated with infection. Biomphalaria snails collected from Chore and Awetu Rivers shaded higher rate of cercariae compared with Kito River. CONCLUSION: A moderate prevalence of S. mansoni infection was shown in the study population. Infection rate among the residents correlated with rate of cercarial shading Biomphalaria snails. Treatment of targeted groups, appropriate health education and environmental measures (e.g. snail control) are needed to improve the situation. KEYWORDS: Prevalence, Intensity, Schistosoma mansoni, Biomphalaria snail

Differences in diagnosis, management, and outcomes of acute febrile illness by health facility level in southern Ethiopia

We assessed the diagnosis, management and outcomes of acute febrile illness in a cohort of febrile children aged under 5 years presenting at one urban and two rural health centres and one tertiary hospital between 11 August 2019 and 01 November 2019. Pneumonia was diagnosed in 104 (30.8%) of 338 children at health centres and 128 (65.0%) of 197 at the hospital (p

Prevalence and risk factors of Hepatitis C among individuals presenting to HIV testing centers, Hawassa city, Southern Ethiopia

<p>Abstract</p> <p>Background</p> <p>Hepatitis C virus (HCV), either alone or in combination with Human Immunodeficiency virus (HIV), constitutes a major public health concern. This study was conducted to describe the prevalence and risk factors for HCV infection in people with and without HIV infection.</p> <p>Methods</p> <p>Blood samples and data on socio-demographic and risk factors for HCV infection were collected from consecutive 400 HIV- positive and 400 HIV- negative individuals attending HIV testing centers in Hawassa city, from October to December, 2008. All sera were tested for antibody to HCV infection (anti-HCV) using enzyme linked immunosorbent assay (ELISA). Sera positive for anti-HCV were further tested for viral ribonucleic acid (RNA) levels using real-time polymerase chain reaction.</p> <p>Results</p> <p>The rate of anti-HCV positivity was 10.5% in the HIV- infected individuals compared with 6% in the HIV negative group (p = 0.002). HCV-RNA was detected in 9.1% of anti-HCV positive samples and rates were comparable between HIV- infected and HIV<b>- </b>non<b>-</b>infected individuals. There was no significant difference in odds of HCV infection in participants with and without HCV risk factors in either HIV sero-group.</p> <p>Conclusion</p> <p>HIV infected individuals had significantly higher rate of anti-HCV although most of them showed no evidence of viraemia. Hence, while priority should be given for HIV infected patients, testing those with anti-HCV for HCV-RNA remains important.</p

Infections with Schistosoma mansoni and geohelminths among school children dwelling along the shore of the Lake Hawassa, southern Ethiopia.

Infections with Schistosoma mansoni and soil-transmitted helminthes (STHs) are major public health problems in Ethiopia. However, information was scarce on the current status of these infections to guide an intervention in the study area. Therefore, this study was conducted to assess the prevalence of infections with S. mansoni and STHs and associated factors among school children in southern Ethiopia.This cross-sectional study investigated children who were attending the Finchawa and Tullo junior elementary schools and were residing along the shore of the lake Hawassa in January and February, 2015. A total of 374 students were selected using systematic random sampling technique. Data on socio-demography and related factors was collected using structured questionnaires. A single stool sample was collected from each child and processed using formol-ether concentration technique and examined microscopically for parasites' ova/larva.The prevalence of parasitic infection with one or more than one helminthiasis was found to be 67.9%. Seven different types of helminths were identified and the most prevalent parasites were Ascaris lumbricoides (44.4%), followed by S. mansoni (31%), Trichuris trichiura (11%), and hookworms (7.7%). The rate of infection with STHs was 52.4%. Single, double, triple and quadruple infections were 42.2, 22.5, 2.4, and 0.8%, respectively. Children who practiced open-field defecation (AOR, 3.6; 95% CI 1.6-8.0; p = 0.001) and had not always washed their hands before eating a meal (AOR, 5.0; 95%CI 2.15-11.7; p <0.001) were more infected with STHs. Moreover, the rate of S. mansoni infection was significantly higher among children who were attending the Finchawa school (AOR, 2.13; 95% CI 1.31-3.46; p = 0.002), aged 11-15 years (AOR, 1.97; 95% CI 1.22-3.19; p = 0.006), had swum in the lake Hawassa (AOR, 2.73; 95%CI 1.20-6.17; p = 0.016), and had involved in irrigation-related activities (AOR, 1.68; 95%CI 1.04-2.71; p = 0.034).The study showed high prevalence of STHs and moderate rate of schisotosomiasis. Mass deworming twice a year for STHs and once every two years for S. mansoni, further to strengthening other prevention measures, is critically needed to reduce these infections to inconsequential level
