Hepatitis A, B and C viral co-infections among HIV-infected adults presenting for care and treatment at Muhimbili National Hospital in Dar es Salaam, Tanzania

<p>Abstract</p> <p>Background</p> <p>Tanzania is currently scaling-up access to anti-retro viral therapy (ART) to reach as many eligible persons as possible. Hepatitis viral co-infections are known to influence progression, management as well as outcome of HIV infection. However, information is scarce regarding the prevalence and predictors of viral hepatitis co-infection among HIV-infected individuals presenting at the HIV care and treatment clinics in the country.</p> <p>Methods</p> <p>A cross-sectional study conducted between April and September 2006 enrolled 260 HIV-1 infected, HAART naïve patients aged ≥18 years presenting at the HIV care and treatment clinic (CTC) of the Muhimbili National Hospital (MNH). The evaluation included clinical assessment and determination of CD4+ T-lymphocyte count, serum transaminases and serology for Hepatitis A, B and C markers by ELISA.</p> <p>Results</p> <p>The prevalence of anti HAV IgM, HBsAg, anti-HBc IgM and anti-HCV IgG antibodies were 3.1%, 17.3%, 2.3% and 18.1%, respectively. Dual co-infection with HBV and HCV occurred in 10 individuals (3.9%), while that of HAV and HBV was detected in two subjects (0.8%). None of the patients had all the three hepatitis viruses. Most patients (81.1%) with hepatitis co-infection neither had specific clinical features nor raised serum transaminases. History of blood transfusion and jaundice were independent predictors for HBsAg and anti-HBc IgM positivity, respectively.</p> <p>Conclusion</p> <p>There is high prevalence of markers for hepatitis B and C infections among HIV infected patients seeking care and treatment at MNH. Clinical features and a raise in serum alanine aminotransferase were of limited predictive values for the viral co-infections. Efforts to scale up HAART should also address co-infections with Hepatitis B and C viruses.</p

Prevalence of hepatitis A, B, C and human immunodeficiency virus seropositivity among patients with acute icteric hepatitis at the Kenyatta National Hospital, Nairobi

Objective: To determine the prevalence of hepatitis A, B, C and HIV seropositivity among patients with acute icteric hepatitis. Design: Cross-sectional descriptive survey. Setting: Kenyatta National Hospital, Nairobi. Subjects: Eighty four patients aged above six months with a history of jaundice not exceeding six months were recruited. There were 47 males and 17 females with an age range of eight months to 67 years and a median age of 25 years. Methods: History was obtained physical examination done and blood taken for determination of bilirubin, ALT, AST and ALP levels. Sera that had disproportionately greater transaminase than ALP elevation were assayed for IgM anti-HAV, IgM anti- HBc, HbsAg, anti-HCV and anti-HlV antibodies. Results: Evidence of hepatitis A, B, and C was round in 41.7%, 26.2%, and 7.1% of the patients respectively, 13.1% of the patients were HBsAg carriers while 30.1% of all patients were HIV positive. Thirty two patients did not have evidence of hepatitis A, B, or C infection and this group was significantly associated with HIV infection (p=0.003). Conclusion: Hepatitis A was the commonest overall type of acute icteric hepatitis seen at the KNH, and among patients aged 15 years and below. Hepatitis B was the leading identified cause of acute hepatitis among those aged over 15 years. Hepatitis C accounted for 7.1% of acute icteric hepatitis 30.1% of all patients and 50% of those admitted with acute hepatitis were also HIV positive.
