Abstract:
Objective To explore the curative effect and safety of traditional Chinese medicine (TCM) plus Kunxian capsule and Huangkui capsule for refractory Henoch-Schonlein purpura (HSP).
Methods From September 2018 to March 2022, 87 patients with refractory HSP were randomized into three groups of A (n=30), B (n=29) and C (n=28) : group A received TCM, group B Kunxian capsule on the basis of TCM and group C Huangkui capsule on the basis of TCM. Subsiding status, recurrent rate, dosing course and adverse events were recorded at Week 2/4/6/8 after medication.
Results After 2-week treatment, the curative effect of group B was significantly better than that of group A/C (P<0.05). After 4-week treatment, the curative effect of group B/C was better than that of group A. And the curative effect of group B was better than that of group C with statistical significance (P<0.05). After 6/8-week treatment, the curative effect of group B/C was better than that of group A and the difference was statistically significant (P<0.05), However, no statistical difference existed between groups B and C (P>0.05). The recurrent rate of rash in group B/C was less than those in group A at Week 2/4/6/8 and the difference was statistically significant (P<0.05). The recurrent rate of rash in group B was less than that in group C at Week 2/4/6 and the difference was statistically significant (P<0.05). However, the recurrent rate of rash in group B/C at Week 8 was not statistically significant (P>0.05). The dosing course was shorter in group B/C than that in group A and the difference was statistically significant (P<0.05). However, no statistical difference existed between groups B and C (P>0.05). The incidence of adverse events in groups A, B and C were 6.67%, 13.79% and 10.71% respectively with no statistical significance (P>0.05).
Conclusion TCM plus Kunxian capsule and Huangkui capsule may promote the regression of rash and lower its recurrent rate in refractory HSP. And TCM plus Kunxian capsule has a better efficacy with a quicker onset and both capsules have no obvious adverse reactions.
