Evaluation of Biochemical and Molecular Parameters of Patients Suffering from Chronic Viral Hepatitis B Treated by a Medicinal Plant Recipe of a Health Care Practitioner in Burkina Faso

Chronic viral hepatitis B (HBV) remains a major public health problem in Burkina Faso. Since access to diagnostic tests and treatments is limited because of their high cost, the majority of the population turn to traditional herbal treatments. This study aimed to evaluate the effectiveness of a plant recipe called Hepatib tiben. It consisted of comparing certain biochemical and molecular parameters of patients infected with HBV that were supported by the recipe. The patients were recruited in Ouagadougou by the traditional health practitioner according to the requirements of the study. Thus 44 patients aged 20 to 61 years and carrier of HBsAg for at least 06 months were treated with Hepatib tiben. The tests were performed in the laboratory before and three months after the treatment. ELISA tests were used to confirm the presence of HBsAg and search for anti-HCV antibodies;transaminases, creatinine were quantified by the “Chem 400” automaton and the viral load of HBV by Real-time PCR. The analysis of the results reveals an improvement of the biochemical and molecular parameters of the patients with the following means (ASAT: 21.02 ± 9.97;ALAT: 21.11 ± 13.27;DNA: 1571.82 ± 3990.97 with p = 0.01 for each). As for HBsAg, its disappearance was observed in 4.55% of patients after treatment. The evaluation of the creatinine parameter explained that the recipe of plants has a tolerated effect on the kidneys of treated patients. These results, while encouraging, need to be complemented by further research for the development of effective phytomedicine to treat and eliminate this viral hepatitis B virus.
