Résumé
The recurrence of hepatitis C (HCV) after liver transplant (LTX) leads to graft fibrosis and cirrhosis. Liver biopsy remains the criterion standard for their diagnosis and monitoring. Our objective was evaluation of shear wave elastography (SWE) in patients with HCV recurrence after LTX and its comparison with histopathologic fibrosis assessment scoring systems. A total of 101 LTX recipients with HCV recurrence (42 women [41.6%] and 59 men [58.4%]) were evaluated by graft biopsy specimens (Ishak, Scheurer, and meta-analysis of histologic data in viral hepatitis [Metavir] score) and SWE (liver stiffness). Median age of patients was 59.4 years; median time from LTX was 84.9 months. The study protocol conforms with the Declaration of Helsinki. Median liver stiffness was 21.3 kPa. To differentiate between liver fibrosis and cirrhosis, patients were divided into 2 subgroups: Ishak score fibrosis (1-4 [85.2%]) and cirrhosis (5-6 [13.9%]); Scheurer score fibrosis (0-3 [85.2%]) and cirrhosis (4 [12.9%]); Metavir score fibrosis (0-3 [85.2%]) and cirrhosis (4 [14.9%]). We have observed statistically significant differences between liver fibrosis and liver cirrhosis groups defined on the basis of Ishak, Scheurer, and Metavir scoring systems: 20.8 kPa vs 29.6 kPa (P = .001), 20.7 kPa vs 30.3 kPa (P = .0005), and 20.7 kPa vs 28.8 kPa (P = .002), respectively. Our results indicate that SWE may be useful in differentiating patients with advanced cirrhosis from those with fibrosis and may be helpful in the noninvasive diagnosis and monitoring of HCV recurrence after LTX.

BACKGROUND
The recurrence of hepatitis C (HCV) after liver transplant (LTX) leads to graft fibrosis and cirrhosis. Liver biopsy remains the criterion standard for their diagnosis and monitoring. Our objective was evaluation of shear wave elastography (SWE) in patients with HCV recurrence after LTX and its comparison with histopathologic fibrosis assessment scoring systems.
METHODS
METHODS
A total of 101 LTX recipients with HCV recurrence (42 women [41.6%] and 59 men [58.4%]) were evaluated by graft biopsy specimens (Ishak, Scheurer, and meta-analysis of histologic data in viral hepatitis [Metavir] score) and SWE (liver stiffness). Median age of patients was 59.4 years; median time from LTX was 84.9 months. The study protocol conforms with the Declaration of Helsinki.

RESULTS
Median liver stiffness was 21.3 kPa. To differentiate between liver fibrosis and cirrhosis, patients were divided into 2 subgroups: Ishak score fibrosis (1-4 [85.2%]) and cirrhosis (5-6 [13.9%]); Scheurer score fibrosis (0-3 [85.2%]) and cirrhosis (4 [12.9%]); Metavir score fibrosis (0-3 [85.2%]) and cirrhosis (4 [14.9%]). We have observed statistically significant differences between liver fibrosis and liver cirrhosis groups defined on the basis of Ishak, Scheurer, and Metavir scoring systems: 20.8 kPa vs 29.6 kPa (P = .001), 20.7 kPa vs 30.3 kPa (P = .0005), and 20.7 kPa vs 28.8 kPa (P = .002), respectively.
CONCLUSIONS
CONCLUSIONS
Our results indicate that SWE may be useful in differentiating patients with advanced cirrhosis from those with fibrosis and may be helpful in the noninvasive diagnosis and monitoring of HCV recurrence after LTX.
