Seronegative and weakly seropositive rheumatoid arthritis differ from clearly seropositive rheumatoid arthritis in HLA class II associations.

The Journal of rheumatology - 1 Aug 1994

Abstract excerpt

OBJECTIVE: To study the role of HLA class II genes in conferring susceptibility to seronegative vs seropositive rheumatoid arthritis (RA). METHODS: The distribution of DRB1 and DPB1 alleles in 33 seronegative, 20 weakly seropositive, 79 distinctly seropositive patients with RA, and in 181 healthy controls was determined by genomic typing: IgM rheumatoid factor (RF) seronegativity was ascertained in Waalers'...
