Systemic lupus erythematosus in twin sisters following ten years of hyperglobulinemic purpura (Waldenström).
Uniovular twin sisters have been diagnosed 10 years ago as having hyperglobulinemic purpura (Waldenström) at age 12. The diagnosis was documented by purpura of the lower extremities, increased gamma-globulin after serum electrophoresis, and increased 7S component upon ultracentrifugation. In addition, there was an elevated ESR, a positive rheumatoid arthritis latex test, and their LE prep. was negative at that time. At a later date, however, both of them developed polyarthritis. After 9 years for the one and 10 years for the other, their LE prep. became strongly and constantly positive, while their gamma-globulin remained within abnormal limits.
