Clinical study of curative effect of compound Qinjiao Pill on palmoplantar pustulosis and its effect on neutrophil/lymphocyte ratio (NLR)

Abstract

Objective To evaluate the efficacy of compound Qinjiao Pill in the treatment of pustulosis palmaris and plantaris and the effect on the neutrophil-to-lymphocyte ratio (NLR). Methods A total of 100 patients with palmoplantar pustulosis who met the inclusion criteria from June 2017 to June 2018 were randomly divided into two groups, 50 in each group. The control group was treated with 308 nm excimer laser twice a week, and the treatment group was treated with one compound Qinjiao Pill once and twice a day. Both groups were treated for 8 weeks and followed up for 3 months. The disease severity was evaluated by the Palmoplantar pustulosis area and severity index (PPPASI), the quality of life was evaluated by the dermatology life quality index (DLQI), the changes of serum NLR were observed, and the clinical efficacy was evaluated. Results The total effective rate was 88.0% (44/50) in the treatment group and 70.0% (35/50) in the control group. The PPPASI scores (t=6.813, 3.091, 3.582, 5.622) and DLQI scores (t=5.713, 4.616, 6.262, 1.824) in the treatment group were significantly lower than those in the control group (P<0.01). After treatment, NEU (4.13 ± 1.42 ×109/L vs. 6.56 ± 1.65 ×109/L, t=7.893), NLR (1.75 ± 0.98 vs. 2.60 ± 0.87, t=4.592). During the treatment, the incidence of adverse reactions was 20.0% (10/50) in the treatment group and 18.0% (9/50) in the control group (χ2=1.680, P=0.089). The recurrence rate of the treatment group was 9.1% (4/44) and that of the control group was 20.0% (7/35). The difference between the two groups was statistically significant (χ2=2.893, P=0.003). Conclusions Compound Qinjiao Pill combined with 308 nm excimer laser can reduce the NLR in peripheral blood, improve the clinical efficacy and reduce the risk of recurrence.
