Abstract:【Objective】To investigate the clinical efficacy of intermittent therapy with isotretinoin capsules combined with clindamycin metronidazole in treating moderate to severe acne. 【Methods】Eighty patients with moderate to severe acne admitted to our hospital from January 2019 to January 2022 were selected as research subjects. Patients were randomly divided into the observation group and control group,with 40 cases each. The observation group was treated with isotretinoin capsule intermittent therapy combined with clindamycin metronidazole topical treatment,while the control group was treated with clindamycin metronidazole topical treatment. The clinical efficacy,the severity (tenderness,flushing) and quantity (pustules,cysts,nodules,blackheads) scores of skin lesions before and after treatment,changes in inflammation factors [tumor necrosis factor-alpha (TNF-α),interleukin-8 (IL-8),Toll-like receptors (TLR)] levels before and after treatment,changes in hormone levels [testosterone (T),progesterone (P),estradiol (E2)] before and after treatment,and the incidence of drug side effects were compared between the two groups. 【Results】The total effective rate of the observation group was significantly higher than that of the control group (P<0.05). The severity and quantity scores of skin lesions in both groups were lower after treatment than before (P<0.05),and the scores in the observation group were lower than those in the control group (P<0.05). After treatment,the levels of TNF-α,IL-8 and TLR in both groups were lower than those before treatment (P<0.05); And their levels in the observation group were lower than those in the control group (P<0.05). The levels of T and P in both groups after treatment were lower than those before treatment,and E2 levels of posttreatment groups were higher than those of pretreatment groups (P<0.05); While posttreatment levels of T and P in the observation group were lower than those in the control group,and E2 level in the observation group was higher than that in the control group (P<0.05). There was no significant difference in the incidence of drug side effects between the two groups (P>0.05). 【Conclusion】The combination of intermittent isotretinoin capsules with clindamycin metronidazole has a significant effect on the treatment of moderate to severe acne. It can effectively reduce the degree of skin lesions,decrease inflammation,adjust hormone levels,and does not significantly increase adverse reactions. Thus it is recommended for clinical application.
