About
The natural history and response to therapy of chronic hepatitis B infection in West Africa are currently poorly understood. In this study, employees of the Cameroon Baptist Convention Health Board (CBCHB) and spouses who are found to be hepatitis B positive on screening will be offered enrollment. Disease monitoring and treatment will be provided following current WHO guidelines. Clinical data will be prospectively recorded for 5 years, and bio-specimens will be frozen for future analysis.
Full description
Chronic hepatitis B (CHB) is common in Cameroon, and hepatitis B-related hepatocellular carcinoma is a leading cause of cancer death throughout West and Central Africa. Little is known about the natural history of CHB in sub-Saharan Africa and the long term response to antiviral therapy. The study hypothesis is that these can be determined by prospective follow-up of a population-based cohort.
Aims, purpose, or objectives:
Methods: Adult employees of the Cameroon Baptist Convention Health Board (CBCHB) and their spouses who are known to be positive for hepatitis B surface antigen (HBsAg+) will be offered the enrollment in a cohort study for CHB. Following enrollment, their stage of disease will be determined using clinical, laboratory and imaging studies. Patients will then be followed at regular intervals for 5 years. Antiviral therapy will be offered to patients who qualify according to current World Health Organization guidelines.
Significance: This protocol will prospectively determine the scope of CHB-related illness in an initially asymptomatic, population-based cohort and the outcomes of current WHO treatment guidelines in this African cohort.
