title: Phenotype of peripheral blood lymphocytes and serum immunoglobulin concentration in patients with early rheumatoid arthritis.
abstract: We studied the phenotype of peripheral blood lymphocytes and serum immunoglobulin concentration in patients with early rheumatoid arthritis and rheumatoid arthritis of more than 12 months duration. Subpopulations of CDIgM+, CD25+, and HLA-DR+ lymphocytes and IgA concentration differed in these groups of patients with rheumatoid arthritis. The count of lymphocytes carrying CDIgM+ and HLA-DR+ receptors correlated with activity of rheumatoid arthritis.
