Transient elastography for predicting liver-related events in cirrhotic HIV-infected patients

We assessed liver stiffness measurement (LSM) for the prediction of mortality and decompensation in HIVinfected patients with compensated liver cirrhosis. A prospective cohort study of HIV-infected patients with confirmed liver cirrhosis from 9 hospitals in Spain. LSM was undertaken for each patient; clinical events were collected prospectively after the baseline visit, and patients were followed until death or the censoring date. We used univariate/multivariate Cox proportional hazard models to evaluate the utility of LSM for predicting the first hepatic decompensation or overall mortality. The sensitivity (SEN), specificity (SPE), positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+) and negative likelihood ratio (LR-) were calculated. The LSM cutoff was selected using ROC curves. We included 102 patients with compensated liver cirrhosis; median [interquartile, (IQR)] follow-up was 36 (21-46) months, median (IQR) CD4+ cell count was 415 cells/μL (307-624) and 94% were receiving antiretroviral therapy. The median (IQR) LSM was 17 kPa (11.7-26). Nineteen events were recorded during follow-up. Multivariate analysis showed that time to hepatic decompensation was associated with CD4+ <200 cells/μL (HR, 26; 95% CI, 1.8- 377; p
