Abstract:
Objective To observe the clinical effect and safety of recombinant human interferon-α2b(rhIFN-α2b)combined with 5-aminolaevulinic acid photodynamic therapy(ALA-PDT)in the treatment of patients with cervical intraepithelial lesions and human papilloma virus(HPV)infection.Methods The clinical data of patients with cervical intraepithelial lesions and HPV infection were analyzed retrospectively.The patients were divided into control group and treatment group according to cohort method.The control group was treated with rhIFN-α2b gel at posterior fornix,qd.On this basis,the treatment group was treated with ALA-PDT,namely applying 5％ALA temperature-sensitive gel prepared by 118 mg of ketone valerate hydrochloride powder for external use on vaginal surface,combined with photodynamic therapy,once a week.The clinical efficacy,time to recovery from clinical symptoms,recurrence rate,changes in cytokines[interleukin-6(IL-6),interleukin-8(IL-8)and interferon-γ(IFN-γ)]and immune function[T cell subsets CD3+,CD4+,CD8+and CD4+/CD8+],and safety were compared between the two groups.Results There were 98 cases in treatment group and 100 cases in control group.The total effective rates in treatment group and control group were 93.88％and 83.00％,with statistically significant difference(P＜0.05).The relief time of lower abdominal pain in treatment group and control group were(3.65±0.52)and(5.26±0.65)d;the time to recovery from abnormal vaginal discharge were(5.77±0.83)and(7.16±0.92)d;the time to recovery from irregular vaginal bleeding were(4.82±0.62)and(6.94±0.77)d;HPV clearance rates were 58.16％and 42.00％;IL-6 levels were(0.16±0.09)and(0.23±0.05)mg·L-1;IL-8 levels were(0.47±0.05)and(0.66±0.07)mg·L-1;IFN-γ levels were(10.07±0.98)and(7.24±0.65)ng·mL-1;CD3+were(71.06±8.29)％and(61.36±6.88)％;CD4+were(48.25±5.94)％and(42.25±5.13)％;CD8+were(20.37±2.42)％and(24.69±2.51)％;CD4+/CD8+were 2.11±0.27 and 1.36±0.16;the differences were all statistically significant(all P＜0.05).Recurrence rates in treatment group and control group were 5.10％and 14.00％,with statistically significant difference(P＜0.05).The total incidence of adverse drug reactions in treatment group and control group were 26.53％and 21.00％,without statistically significant difference(P＞0.05).Conclusion The combined treatment of rhIFN-α2b and ALA-PDT is effective for patients with cervical intraepithelial lesions and HPV infection.It has obvious advantages in improving immunity,relieving inflammatory response and reducing recurrence rate,with good safety.
