Clinical Observation of Thymosin in Adjunctive Treatment of Chronic Eczema / 中国药房

ABSTRACT

OBJECTIVE:To observe clinical efficacy and safety of thymosin in adjunctive treatment of chronic eczema,and to investigate its mechanism from the change of peripheral T lymphocyte subsets. METHODS:160 patients with chronic eczema were randomly divided into observation group and control group,with 80 cases in each group. Both group received conventional therapy as mizolastine,Desonide cream. Observation group additionally received Thymosin enteric-coated tablet 20 mg,po,tid;control group was given placebo the appearance of which was same with Thymosin enteric-coated tablet. Treatment course lasted for 4 weeks. The change of T lymphocyte subsets,clinical efficacy and the occurrence of ADR were compared between 2 groups. Re-currence rate of both groups were followed up for 1 year. RESULTS:The effective rate of observation group(91.25%)was signifi-cantly higher than that of control group(77.50%),with statistical significance(P0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). Re-currence rate of observation group(31.51%)was significantly lower than that of control group(64.52%)during follow-up period, with statistical significance (P<0.05). CONCLUSIONS:In summary,thymosin can improve clinical efficacy and reduce recur-rence rate by regulating T lymphocyte subsets with good safety.
