Use of transient elastography (FibroScan(R)) for the noninvasive assessment of portal hypertension in HIV/HCV-coinfected patients

2011 Journal of viral hepatitis 18;10 (685-691)

The hepatic venous pressure gradient (HVPG) is the gold standard for assessing portal pressure and correlates with the occurrence of portal hypertension (PH)-related complications. Transient elastography (TE) is a new, highly accurate noninvasive technique, which enables us to evaluate hepatic fibrosis to detect advanced fibrosis and cirrhosis. We performed a hepatic haemodynamic study and TE in 38 HIV/HCV-coinfected patients. The association between HVPG and liver stiffness was assessed by linear regression. The diagnostic value of TE was assessed by receiver operating characteristic (ROC) curves. We considered clinically significant PH as an HVPG >/= 10 mmHg and severe PH as an HVPG >/= 12 mmHg. A total of 38 HIV/HCV-coinfected patients were included. Twenty-eight patients (73.7%) had clinically significant PH (HVPG >/= 10 mmHg), and 23 (60.5%) of these had severe PH (HVPG >/= 12 mmHg). We found a statistically significant association between liver stiffness (kPa) and HVPG (r(2) = 0.46, P /= 10 and >/= 12 mmHg, respectively. Our data suggest that TE can predict the presence of clinically significant and severe PH in HIV/HCV-coinfected patients.
