OBJECTIVES: To determine the diagnostic accuracy of TE in predicting fibrosis in HIV/HCV-coinfected patients, and to compare it with published non-invasive serum markers.
Fibrosis Score (METAVIR)
Table 1: characteristics and the distribution for fibrosis stage and activity grade
Liver stiffness measurements ranged from 2.7 to 43.5 kPa. The median (IQR) of liver stiffness according to the different stages of fibrosis (in kPa) was as follows: F0, 4.9 (4.1-6.5); F1, 6.1 (5.3-8.6); F2, 8.4 (5.8-10.5); F3, 11.9 (8.8-16.6); and F4, 31.4 (22.5-40.3) (Fig.1)
We assessed the diagnostic accuracy of TE for different categories of fibrosis. Based on the AUROC curves, three cut-off values were chosen to identify F≤1 (<7 kPa), F≥3 (≥ 11.5 kPa), and F4 (≥ 14 kPa). Table 2.

TE accurately identified patients with advanced liver fibrosis and cirrhosis, and patients with mild fibrosis
We found that TE outperformed other noninvasive indexes in the diagnosis of liver fibrosis in HIV/HCV-coinfected patients.
Our results suggest that TE is a safe, rapid, and accurate tool that can help guide treatment decisions in HIV/HCV-coinfected patients.
