aceDynamic prediction of HIV-related incomplete immune reconstitution: A multicenter, large cohort study using advanced joint modeling
Abstract: Incomplete immune reconstitution (IIR) is a serious complication affecting 10 to 40% of people living with HIV (PLWH) despite effective antiretroviral therapy, leading to increased morbidity and mortality. Current risk prediction models rely on single-time point measurements and lack dynamic assessment capabilities. We developed a dynamic joint prediction system for IIR risk (DJPSIIR) using Bayesian joint modeling to analyze longitudinal data from 21,862 PLWH across 31 Chinese provinces (2003-2024). The system i…

Researchers developed a dynamic joint prediction system for incomplete immune reconstitution risk in people living with HIV using Bayesian joint modeling of longitudinal CD4+ counts and CD4/CD8 ratios from 21,862 patients across 31 Chinese provinces between 2003 and 2024.
The system showed strong discriminatory performance for long-term risk and outperformed experts and other machine learning methods, suggesting potential to improve HIV care through earlier identification of high-risk patients, though real-world clinical impact and generalizability beyond the studied cohort remain to be demonstrated.
- Study analyzed longitudinal data from 21,862 people living with HIV across 31 Chinese provinces from 2003-2024.
- System named DJPSIIR integrates continuous CD4+ T cell counts and CD4/CD8 ratios with clinical parameters for real-time risk prediction.
- Model achieved AUCs of 0.890 to 0.912 for 5- to 7-year predictions and outperformed expert assessments and 19 machine learning algorithms across validation cohorts.
A Bayesian joint modeling system that integrates longitudinal CD4+ counts and CD4/CD8 ratios predicted 5- to 7-year risk of incomplete immune reconstitution in people living with HIV with high discrimination, enabling real-time identification of high-risk patients for timely intervention.
The rundown
Researchers built DJPSIIR using Bayesian joint modeling of longitudinal CD4+ counts and CD4/CD8 ratios plus clinical parameters from a multicenter cohort of 21,862 PLWH collected between 2003 and 2024 across 31 provinces.
Validation showed AUCs of 0.890 to 0.912 for 5- to 7-year IIR predictions, with performance consistently exceeding both expert assessments and 19 machine learning algorithms, addressing prior models that relied on single-time point measurements.
