基于PI3K/Akt/mTOR信号通路探讨他克莫司联合多西环素对慢性子宫内膜炎的疗效及机制
Investigation of the efficacy and mechanism of tacrolimus combined with Doxycycline in the treatment of chronic endometritis via the PI3K/Akt/mTOR signaling pathway
Objective To evaluate the efficacy of tacrolimus-doxycycline combination therapy for chronic endometritis (CE) and explore its mechanisms through PI3K/Akt/mTOR signaling pathway modulation. Methods Ninety-four CE patients treated at our hospital (January 2021-January 2023) were randomly assigned to either doxycycline monotherapy (control group, n = 47) or tacrolimus-doxycycline combination therapy (observation group, n = 47). Outcomes included: clinical efficacy; PI3K/Akt/mTOR mRNA expression; serum inflammatory cytokines [IL-1β, TNF-α, IL-6, IFN-γ, IL-10]; T-cell subsets (CD4⁺, CD8⁺, CD4⁺/CD8⁺ ratio); 12-month recurrence rate; and adverse events. Results The observation group demonstrated significantly higher overall efficacy (P < 0.05) and greater reductions in PI3K, Akt, and mTOR mRNA expression (P < 0.05). Combination therapy yielded significantly larger decreases in proinflammatory cytokines (IL-1β, TNF-α, IL-6, IFN-γ) and greater IL-10 elevation vs. monotherapy (P < 0.05). Post-treatment, observation group showed: Significantly lower IL-1β, TNF-α, IL-6, IFN-γ concentrations (P < 0.05); Higher IL-10 levels (P < 0.05); Greater CD4⁺ T-cell increase (P < 0.05); and Reduced CD38⁺ and CD138⁺ plasma cell positivity (P < 0.05). No significant intergroup differences were observed in CD8⁺ T-cells, CD4⁺/CD8⁺ ratio, or 12-month recurrence rate (21.28% vs. 31.91%, P > 0.05). The adverse event incidence was significantly lower with combination therapy (P < 0.05). Conclusion Tacrolimus-doxycycline combination therapy significantly improves CE outcomes by modulating PI3K/Akt/mTOR signaling, attenuating inflammation, enhancing CD4⁺ T-cell response, and reducing plasma cell infiltration, with favorable safety profile.
