title: [Intermittent intravenous cyclophosphamide application in patients with systemic lupus erythematosus].
abstract: The aim of this paper is retrospective analysis of data from patients in whom the indication for cyclophosphamide (CF) pulse therapy was established in our department. Indications for CF pulse treatment were lupus nephritis (LN) alone or associated with central nervous system lupus. CF was administred in the dose of 500-1000 mg/m2 intravenously once monthly for the 6 months and once every 3 months thereafter. Patients were treated with adequate dose of glucocorticoids and other symptomatic therapy. The effect of applied therapy has been analysed by monitoring proteinuria, serum creatinine concentration, creatinine clearance, ESR, ANF titer and total complement hemolytic activity. Initial therapeutic procedure has been completed in 25/30 patients. The reasons for discontinuation in 5/30 patients were as follows: end-stage renal failure in spite of therapy (1), psychosis and lost of compliance (1), recurrent pancytopenia and subsequent sepsis (1), death non related to SLE (1) and failure to show at follow-up (1). Significant improvement of all control parameters was observed in the majority of patients in whom the therapy was completely conducted. 16/25 patients continued therapy for the next 18 months and in only 1/16 patients therapy was discontinued because of end-stage renal failure. In other 15/16 patients further improvement of control parameters was observed, although not so expressed as in the first 6 months. The most frequent complications were infections (16 infections were microbiologically proved and there were probably more infections). Alopecia (2), haematuria (1) and amenorrhoea (1) were also observed. Relatively low incidence of complications may be explained by careful patient monitoring. Considering that therapeutic success is defined not only by the improvement of renal function, but by stopping of further progression of renal failure, it can be concluded that intermittent CF pulse therapy showed good effect on LN in patients with clear indication.
