title: Demonstration of cytomegalovirus (CMV) DNA and anti-CMV response in the synovial membrane and serum of patients with rheumatoid arthritis.
abstract: One hundred forty-seven synovial membranes were investigated for the presence of human cytomegalovirus (CMV). In 11 of 83 synovial membranes of patients with rheumatoid arthritis (RA), but only in 2 of 64 synovial membranes from patients with other joint disorders, CMV-DNA could be detected by the polymerase chain reaction (PCR) technique (p less than 0.05). In contrast, the percentage of seropositive patients was not significantly different between the 2 groups of patients and no blood sample from any patient tested revealed the presence of CMV by PCR. Only in patients with RA and CMV positive synovial membranes was the titer of CMV specific antibodies in the synovia higher than in the serum. Thus, the local presence of CMV in the synovial membrane and associated local antiviral responses might participate in the pathogenesis of synovitis in a minority of patients with RA.
