The existence of geographical clusters of cases of inflammatory polyarthritis in a primary care based register

Article Abstract:

Researchers have discovered three geographical clusters of inflammatory arthritis in Norfolk, UK, where the incidence of the disease is much higher than expected. More research is needed to determine if there is some environmental agent that causes arthritis.

Proposal to establish a register for the long term surveillance of adverse events in patients with rheumatic diseases exposed to biological agents: the EULAR Surveillance Register for Biological Compounds

Article Abstract:

These compounds include drugs and antibodies that block the activity of tumor necrosis factor as well as immunosuppressive drugs.

Low frequency of recent parvovirus infection in a population-based cohort of patients with early inflammatory polyarthritis

Article Abstract:

Parvovirus infection does not appear to be associated with most new cases of inflammatory polyarthritis (IP). Parvovirus infection can cause temporary arthritic symptoms. Researchers examined 147 patients newly diagnosed with IP, the acute inflammation of two or more joints, to detect antibodies to parvovirus B19. Only 3% of the patients had evidence of a recent parvovirus infection, and 75% of these patients satisfied diagnostic criteria for rheumatoid arthritis, an autoimmune joint disease.
