Abstract:
A female patient with IgM RF seropositive rheumatoid arthritis according to criteria of the American Rheumatism Association was treated for 133 months with Penicillamine and for 17 months also with Sulfasalazine. Both types of treatment were discontinued because the patient developed symptoms meeting diagnostic criteria of systemic lupus erythematosus, as defined by the same society. Early recognition of this diagnosis was made possible by regular follow up of clinical and laboratory data (ANA, anti DNP, anti dsDNA, C3, C4 and others). Marked improvement, incl. improvement of the nephropathy, was recorded after pulsed treatment with methylprednisolone.
