Chronic viral HBeAg-negative hepatitis B: Epidemiological, clinical and biochemical characteristics in an outpatient descriptive cohort in Burkina Faso

Abstract

IntroductionOur study aimed to describe epidemiological and diagnostic features in an outpatient's cohort with chronic HBeAg-negative hepatitis B. Patients and methodsA cross-sectional descriptive study with a retrospective data collection was implemented from January 2004 to April 2016 in the hepato-gastroenterology department of the University Teaching Hospital Yalgado Ouédraogo (CHU-YO) in Burkina Faso. ResultsOverall 325 HBeAg negative patients met the inclusion criteria. The sex ratio was 1.5 and the mean age 38.7 years. The most frequent circumstance of diagnosis was the health check-up (54.5%). The mean HBsAg concentration and viral load were 7861.6 IU/mL and 32 237.20 IU/mL, respectively. Low or moderate inflammatory activity was found in 44% and 24% of patients, respectively at the liver biopsy; 32% presented a portal fibrosis with some septa (F2). 43.9% and 41.6% had low (A1) or moderate (A2) inflammatory activity, respectively at the hepatic fibrosis blood test, while 59.1% and 20.4% had low (F1) or moderate (F2) fibrosis stage, respectively. Of the five biochemical and virological profiles among the untreated patients, the profile 1 represented 67.2% of the sample. ConclusionThe proportions of negative HBeAg in chronic hepatitis B patients are increasing in Burkina Faso. Most of the patients have a high viral load, a low to moderate inflammatory activity or fibrosis stage.
