Randomized, double‑blind, double‑dummy clinical study of Shaodi Xiegan Granules in treatment of progressive psoriasis vulgaris with emotional comorbidities
To evaluate the clinical efficacy and safety of Shaodi Xiegan Granules (SXG) in treating patients with progressive psoriasis vulgaris (PV) and associated emotional comorbidities.
Methods
2
Eighty subjects with progressive PV and emotional comorbidities were randomly assigned to either the treatment group (
n
=40) or the control group (
n
=40). The treatment group received oral SXG and the placebo of Compound Aminopeptide Tablets, while the control group received oral Compound Aminopeptide Tablets and the SXG placebo for 8 weeks. Clinical efficacy was evaluated. Changes in the psoriasis area and severity index (PASI), visual analogue scale (VAS) for pruritus, Pittsburgh sleep quality index (PSQI), Hamilton anxiety rating scale (HAMA), and Hamilton depression rating scale (HAMD) were compared between the two groups. Serum levels of tumor necrosis factor‑α (TNF‑α), interleukin (IL)-6, IL-17, 5‑hydroxytryptamine (5-HT), and brain-derived neurotrophic factor (BDNF) were also measured before and after intervention.
Results
2
①A total of 72 subjects completed the trial, with 36 in each group. ②The clinical efficacy of the treatment group was superior to that of the control group(
P
<
0.05
). ③After treatment, the scores of PASI, itching VAS, PSQI, HAMA, and HAMD in the treatment group decreased(
P
<
0.05), and the decrease was more significant than that in the control group (
P
<
0.05). ④After treatment, the levels of TNF-α, IL-6, and IL-17 decreased in both groups(
P
<
0.05), with a more significant decrease in the treatment group for IL-6 level (
P
<
0.05).⑤After treatment, the levels of 5-HT and BDNF increased in the treatment group(
P
<
0.05), while only the level of 5-HT increased in the control group(
P
<
0.05). The levels of 5-HT and BDNF in the treatment group were significantly higher than those in the control group(
P
<
0.05). ⑥No serious adverse events were reported in either group.
Conclusions
2
SXG effectively alleviates inflammatory skin lesions in patients with progressive PV and emotional comorbidities to a certain extent. Furthermore, the treatment significantly improves anxiety, depression, and sleep quality. The therapeutic mechanism may be associated with the downregulation of pro-inflammatory cytokines and the upregulation of neurotransmitters involved in mood and sleep regulation.
