Abstract

The aim of this study was to determine the cumulative probability of taking CsA in comparison to other DMARDs, as well as the reason for discontinuation of each DMARD, in a large cohort of PsA patients. We prospectively studied 172 consecutive patients with a diagnosis of PsA who had been admitted to our rheumatological unit since 1984. We collected information about treatment with DMARDs including: number, dose, duration and causes of withdrawal, including side effects or inefficacy. Cumulative survival analysis was performed by the Kaplan-Meier test and the differences between these survival curves were determined by the Mantel-Hanszel test. The probability curve of continuing to take CsA was significantly lower than that of MTX (p < 0.046). The rate of adverse effects responsible for stopping DMARD therapy was higher in the CsA group, especially with respect to the antimalarial group (p < 0.014). The most common cause of CsA withdrawal was hypertension. The rate of withdrawal due to inefficacy in the CsA group was not significantly different from those observed in the other groups. Nevertheless, the total frequency of discontinuation due to toxicity and inefficacy in the MTX group was significantly lower compared to the gold...Continue Reading
