ABSTRACT
This 12-year cohort study of 80 long-term non-progressors (LTNPs) observed a cumulative follow-up duration of 628.5 person-years. Among them, 60 received antiretroviral therapy (ART) for a total of 418.6 person-years. Twenty-four deaths occurred during the follow-up period, with an average age of 42.36 years and a lowest 8-year survival rate of 0.90. Cox model analysis revealed that the risk of AIDS-related death was 1.47 times higher for non-marital, non-commercial heterosexual transmission than for injection drug use. Treatment initiation at ages 31-40 was correlated with an elevated risk of mortality, while treatment for 3-10 years reduced mortality risks in untreated LTNPs. Flow cytometry observed significant differences in the proportion of NK cells. Long-term ART (> 2 years) before LTNPs developed AIDS symptoms could lower mortality risk and potentially extend lifespan, especially when it was initiated at a younger age without affecting NK cell balance. Epidemiological and immunological studies on ART-treated LTNPs are vital for advancing HIV treatment and achieving functional cures for AIDS individuals.
RESUMEN
RESUMEN Este estudio de cohorte de 12 años con 80 no progresores a largo plazo (LTNPs) observó un total acumulado de 628.5 personas-año. De ellos, 60 recibieron terapia antirretroviral (TAR) durante un total de 418.6 personas-año. Se produjeron veinticuatro muertes durante el período del estudio, con una edad promedio de 42.36 años y una tasa de supervivencia más baja de 0.90 a los 8 años. El análisis del modelo de Cox identificó que la transmisión heterosexual no marital ni comercial presentaba un riesgo 1.47 veces mayor de muerte relacionada con el SIDA en comparación con el uso de drogas inyectables. Comenzar el tratamiento entre los 31-40 años mostró incrementos en los riesgos de mortalidad, mientras que 3-10 años de tratamiento redujeron los riesgos de mortalidad en LTNPs no tratados. Se observaron diferencias significativas en las proporciones de células NK desde el punto de vista inmunológico. La TAR a largo plazo (> 2 años) antes de la aparición de síntomas del SIDA en LTNPs podría disminuir el riesgo de mortalidad y potencialmente prolongar la vida, especialmente si se inicia a una edad más temprana sin afectar el equilibrio de las células NK. Los estudios epidemiológicos e inmunológicos sobre LTNPs tratados con TAR son fundamentales para el progreso del tratamiento del VIH y la cura funcional del SIDA.
