  1. Risk factors for serious infection during treatment with cyclophosphamide and high-dose corticosteroids for systemic lupus erythematosus.

    Article - En anglais


    To determine risk factors for serious infection during treatment with cyclophosphamide (CYC) and high-dose corticosteroids in systemic lupus erythematosus (SLE).


    Records of 100 SLE patients who had received CYC were examined for documentation of serious infections that occurred during CYC therapy and the subsequent 3 months.


    Infection occurred in 45 of 100 patients during CYC therapy.

    Patients with infection were more likely to have multiple organ disease (49% versus 29% ; P=0.04), a lower nadir in the white blood cell (WBC) count (2,818 versus 3,558 cells/mul ; P=0.02), and a higher maximum corticosteroid dose (195 versus 73 mg ; P<0.01) than patients without infection.

    Infection occurred with equal prevalence in those who received intravenous (IV) (39%) or oral (40%) CYC, but was more common with use of sequential IV and oral therapy (68%). By multivariate analysis, the strongest association with infection was a WBC nadir ¾3,000 cells/mul (odds ratio [OR] 2.8,95% confidence interval [95% CI] 1.4-5.5) and use of sequential IV and oral CYC (OR 2.3,95% CI 1.2-4.3).

    Infection occurred in more CYC-treated patients taking concomitant steroids than in those treated with high-dose steroids alone (45% versus 12% ; P=0.001).

    Fatal and opportunistic infections during CYC therapy were associated with a low WBC nadir and a high maximum corticosteroid dose.
