title: IgG (kappa) paraproteinaemia and arthritis.
abstract: Three patients with IgG (kappa) paraproteinaemia in association with inflammatory polyarthritis are described. Two of the patients had an erosive deforming arthritis, and the third had a non-erosive arthritis and necrotizing vasculitis. Possible aetiological relationships between the paraproteinaemia, arthritis and vasculitis are discussed.
