The efficacy and safety of cyclosporine A plus androgen versus androgen alone for adult patients with non-severe aplastic anemia in China: a meta-analysis of randomized controlled trials.

Whether combined CsA with androgen therapy was superior to androgen therapy alone in NSAA remains controversial. This study aimed to assess the efficacy and safety of combined therapy versus androgen therapy for NSAA patients using a meta-analytic approach. An electronic database of PubMed, EmBase, Cochrane library, CNKI, VIP, and Wanfang was systematically searched for randomized controlled trials (RCTs) from their inception to February 2020. The primary endpoint was effective rate, while the secondary endpoints included white blood cell (WBC), hemoglobin, platelet, and potential adverse events. The pooled results from included trials were calculated with the random-effects model. Forty-three RCTs recruited 2610 NSAA patients for the final quantitative meta-analysis. We noted that combined therapy was associated with an increased incidence of effective rate than androgen therapy alone (relative risk [RR]: 1.35; 95% confidence interval [CI]: 1.29–1.41; P < 0.001). Moreover, patients treated with combined therapy were associated with higher WBC (weighted mean difference [WMD]: 1.22; 95%CI: 0.94–1.49; P < 0.001), hemoglobin (WMD: 12.93; 95%CI: 8.86–17.01; P < 0.001), and platelet (WMD: 8.65; 95%CI: 7.05–10.24; P < 0.001). Finally, the pooled incidence of hirsutism, handshake, gingiva hyperplasia, liver function damage, and renal function damage were 0.35 (95%CI: 0.22–0.48), 0.24 (95%CI: 0.15–0.32), 0.22 (95%CI: 0.10–0.35), 0.19 (95%CI: 0.14–0.25), and 0.06 (95%CI: 0.01–0.11), respectively. This study found that combined CsA with androgen therapy was superior to androgen therapy alone for Chinese patients with NSAA, and the most common adverse of combined therapy included hirsutism, handshake, gingiva hyperplasia, liver function damage, and renal function damage.
