ABSTRACT
PURPOSE:
Rheumatoid arthritis is the most common chronic inflammatory joint disease in adults. In Senegal, where biotherapy is unavailable, treatment of RA relies on a combination of glucocorticoids and disease-modifying antirheumatic drugs (DMARD). Since DMARD, particularly methotrexate, induce hepatotoxicity pretreatment assays of serum transaminase and albumin levels, as well as serological tests for the hepatitis B and C viruses is recommended. Hepatitis B virus (HBV) infection is endemic in Africa, particularly in Senegal. The purpose of this study was to assess the seroprevalence of the HBV surface antigen (HBsAg) for HBV in 258 patients with RA in Senegal as a basis for defining the least hepatotoxic DMARD for these patients and ensuring the most suitable monitoring.METHOD:
This retrospective study was based on a review of the medical records of patients examined between January 2005 and December 2009 at the rheumatology outpatient clinic of the Aristide Le Dantec Teaching Hospital in Dakar, Senegal. All patients met the American College of Rheumatology criteria for RA.RESULTS:
A total of 258 patients were tested for HBsAg. Tests were positive in 6 for a seroprevalence of 2.3%. All 6 positive patients were women with a mean age of 48.7 years (range, 16-79 years). Transaminase levels were normal in 5 patients. In the remaining patient, ASAT level elevation were twice normal and ALAT was normal. No patients had clinical evidence of liver disease.CONCLUSION:
HBsAg seroprevalence in our population of patients with RA was lower than in the general population of Senegal 2.3% versus 15%-18%. No evidence indicated that HBVinfection produced specific features in patients with RA. Based on these findings, widespread use of methotrexate in optimal dosages appears safe in patients with RA in Senegal. Treatment should be accompanied by careful attention to HBV prevention.
