Qiling Yiqi Tablets Plus Antiretroviral Therapy for HIV Immune Non-responders With Lung-Spleen Qi Deficiency

This pragmatic randomized controlled trial evaluates whether Qiling Yiqi Tablets combined with antiretroviral therapy (ART) improves immune reconstitution in people with HIV who meet criteria for immune reconstitution failure and lung-spleen qi deficiency syndrome. Eligible participants are adults aged 18 to 60 years with HIV-1 infection, long-term viral suppression on ART, and persistently low CD4+ T-cell counts. A total of 240 participants will be randomized 1:1 to receive Qiling Yiqi Tablets plus ART or ART alone. Treatment lasts 48 weeks, followed by 48 weeks of follow-up. The primary outcomes are absolute CD4+ T-cell count and immune reconstitution response rate. Secondary outcomes include immune homeostasis markers, T-cell activation and Treg proportion, thymic output and inflammation-related markers, HIV RNA viral load, quality of life, clinical symptom scores, all-cause mortality, and safety.
