['Our aim was to assess the predictive value of liver stiffness (LS), measured by transient elastography (TE), for clinical outcome in human immunodeficiency virus / hepatitis C virus (HIV/HCV)-coinfected patients with compensated liver cirrhosis. This was a prospective cohort study of 239 consecutive HIV/HCV-coinfected patients with a new diagnosis of cirrhosis, done by TE, and no previous decompensation of liver disease. The time from diagnosis to the first liver decompensation and death from liver disease, as well as the predictors of these outcomes, were evaluated. After a median (Q1-Q3) follow-up of 20 (9-34) months, 31 (13%, 95% confidence interval [CI]: 9%-17%) patients developed a decompensation. The incidence of decompensation was 6.7 cases per 100 person-years (95% CI, 4.7-9-6). Fourteen (8%) out of 181 patients with a baseline LS < 40 kPa developed a decompensation versus 17 (29%) out of 58 with LS ≥ 40 kPa (P = 0.001). Factors independently associated with decompensation were Child-Turcotte-Pugh (CTP) class B versus A (hazard ratio [HR] 7.7; 95% CI 3.3-18.5; P < 0.0001), log-plasma HCV RNA load (HR 2.1; 95% CI 1.2-3.6; P = 0.01), hepatitis B virus coinfection (HR, 10.3; 95% CI, 2.1-50.4; P = 0.004) and baseline LS (HR 1.03; 95% CI 1.01-1.05; P = 0.02). Fifteen (6%, 95% CI: 3.5%-9.9%) patients died, 10 of them due to liver disease, and one underwent liver transplantation. CTP class B (HR 16.5; 95% CI 3.4-68.2; P < 0.0001) and previous exposure to HCV therapy (HR 7.4; 95% CI 1.7-32.4, P = 0.007) were independently associated with liver-related death; baseline LS (HR 1.03; 95% CI 0.98-1.07; P = 0.08) was of borderline significance.'] Does liver stiffness predict clinical outcome in human immunodeficiency virus/hepatitis C virus-coinfected patients with compensated liver cirrhosis?
