Document 0471 DOCN M9460471 TI The absence of antibodies to malaria and human immunodeficiency virus, and the presence of hepatitis B surface antigen as diagnostic markers of rheumatoid arthritis. DT 9404 AU Adebajo AO; Hazleman BL; Rheumatology Research Unit, Addenbrooke's Hospital Cambridge,; United Kingdom. SO Clin Rheumatol. 1993 Dec;12(4):467-70. Unique Identifier : AIDSLINE MED/94170582 AB Rheumatoid factor is of limited value in the diagnosis of rheumatoid arthritis (RA) in West Africa. Consequent upon previous findings, we have studied the role of the absence of antibodies to malaria and human immunodeficiency virus (HIV) as well as the presence of the hepatitis B surface antigen (HBsAg) as diagnostic markers of rheumatoid arthritis in West Africa. We have found a significant association (p < 0.001) between RA and titre of HBsAg, but only between RA and malaria (p < 0.05) when sera with low malaria antibodies were studied. No correlation between either HBsAg or malaria and rheumatoid factor was found and no RA patient was either HIV-1 or HIV-2 positive.
