Abstract:Objective To study the clinical efficacy of estrogen combined with Baofukang suppository in the treatment of cervical human papillomavirus (HPV) infection in postmenopausal women.Methods A total of 89 postmenopausal patients with cervical HPV infection admitted to our hospital from February 2019 to July 2022 were selected and divided into study group (n = 46) and control group (n = 43) according to different treatment methods. The control group received estrogen therapy, and the study group received Baofukang suppository therapy on the basis of the estrogen therapy. Both groups were treated for 3 months. The duration of abnormal discharge, time to negative conversion of HPV, clinical efficacy, inflammatory factors, immune function, LCT score, cervical inflammation score and adverse reactions were compared between the two groups.Results The duration of abnormal discharge and the time to negative conversion of HPV in the study group were shorter than those in the control group (P < 0.05). The overall effective rate of the study group was higher than that of the control group (P < 0.05). The differences of interleukin-4 (IL-4), interferon-γ (IFN-γ), interleukin-2 (IL-2) and tumor necrosis factor-α (TNF-α) before and after treatment in the study group were higher than those in the control group (P < 0.05). The differences of the frequency of CD3+, CD19+, CD3+ CD8+ and CD3-CD56+ cells before and after treatment in the study group were higher than those in the control group (P < 0.05). The differences of the LCT score and the cervical inflammation score before and after treatment in the study group were higher than those in the control group (P < 0.05). There was no significant difference in the overall incidence of adverse reactions between the two groups (P > 0.05).Conclusions Estrogen combined with Baofukang suppository is effective in the treatment of cervical HPV infection in postmenopausal women, by promoting the negative conversion of HPV, improving the immune function of patients, and reducing cervical inflammation with being safe and reliable.
