Seronegative rheumatoid arthritis and HLA-DR4.

The Journal of rheumatology - 1 Feb 1994

al-Jarallah K F, Buchanan W W, Sastry A, Singal D P

Abstract excerpt

OBJECTIVE: To investigate the prevalence of HLA-D region antigens in patients with seronegative rheumatoid arthritis (RA). METHODS: The distribution of HLA-D region antigens was studied in 33 patients with seronegative RA. All patients were followed for at least 3 years, during which tests for IgM rheumatoid factor were negative on at least 3 occasions. HLA-D region antigens were defined by serological and...
