Abstract

OBJECTIVE:

To evaluate the response to treatment in a large cohort of patients with systemic lupus erythematosus (SLE) associated with autoimmune thrombocytopenia.

METHODS:

Response to treatment was assessed retrospectively in 59 patients with SLE, either definite (n = 44) or incomplete (n = 15), associated with frank autoimmune thrombocytopenia (defined as platelet count < 50 x 10(9)/l). Response to treatment was classified as complete (CR: platelet count > 150 x 10(9)/l), partial (PR: platelet count > 50 x 10/l), or failure (FR) in the other cases.

RESULTS:

Oral prednisone alone was used in 50 of the 59 patients (mean initial dose 1 mg/kg body weight/day). A response was obtained in 80% of cases (CR in 28. PR in 12) but only 11 (22%) had a sustained response (CR, n = 7; PR, n = 4). In contrast, combined treatment with prednisone and either danazol (n = 18) or hydroxychloroquine (n = 11) resulted in 50% (7 CR, 2 PR) and 64% (4 CR, 3 PR) longterm responses, respectively, allowing prednisone to be withdrawn or the dose tapered below 0.2 mg/kg body weight/day. High dose methylprednisolone pulses (n = 10) and intravenous immunoglobulin (IVIG) (n = 31) resulted in positive responses in 60% (4 CR, 2 PR) and 65% (12 CR, 8 PR) of cases, respectively, but the response was transient in each case. Splenectomy (n = 17) resulted in 65% longterm responses (10 CR, 1 PR). Only 2 longterm partial responses were obtained with the 22 immunosuppressant-containing regimens administered to 14 patients. At the end of the study. a response was observed in 52 (88%) patients [CR: 36 (61%), PR: 16 (27%)], mainly as a result of splenectomy or combined treatment with prednisone and either danazol or hydroxychloroquine.

CONCLUSION:

Longterm remission was obtained in the majority of patients. The major treatments inducing remission were splenectomy and prednisone combined with danazol or hydroxychloroquine.
