Abstract: Objective To investigate the efficacy of thalidomide combined with a second-line regimen in the treatment of patients with relapsed and refractory immune thrombocytopenic purpura (ITP) and its effect on Th1/Th2 cytokines. Methods From January 2016 to March 2021, 86 patients with relapsed and refractory ITP admitted to Bozhou people's Hospital were enrolled and randomly divided into observation group and control group, with 43 patients in each group. The control group was treated with dexamethasone and rituximab, and the observation group was given thalidomide orally on top of the control group regimen. The curative effect was evaluated at 12 weeks of treatment in both groups. The changes in bleeding score, platelet count (PLT), Th1 cytokine [tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ) and interleukin-2 (IL-2)] and Th2 cytokine [interleukin-4 (IL-4) and interleukin-10 (IL-10)] levels were compared before treatment and at 12 weeks of treatment. Results The total effective rate of treatment in the observation group was 93.02%, which was significantly higher than that in the control group (72.09%) (P<0.05). At 12 weeks of treatment, the bleeding scores of both groups were lower than before treatment (P<0.05), and the bleeding scores of the observation group were significantly lower than those of the control group (P<0.001); the PLT count of the observation group was significantly higher than that of the control group (P<0.001); the serum TNF-α, IFN-γ and IL-2 levels of both groups were significantly lower than those before treatment (P<0.05), and the observation group was significantly lower than that of the control group (P<0.001); serum IL-4 and IL-10 levels were significantly higher than before treatment (P<0.05), and the observation group was significantly higher than the control group (P<0.001). Conclusion Thalidomide combined with the second-line regimen has a significant clinical effect in the treatment of patients with relapsed and refractory ITP, which can regulate the levels of Th1/Th2 cytokines.
