 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.
