Long‐term effects on cirrhosis and portal hypertension of direct antiviral agent (DAA)‐based eradication of hepatitis C virus (HCV) are still under debate. We analysed dynamics of liver and spleen elastography to assess potential regression of cirrhosis and portal hypertension 3 years post‐treatment. Fifty‐four patients with HCV‐associated cirrhosis and DAA‐induced SVR were included. Liver and spleen stiffness were measured at baseline (BL), end of treatment (EOT), 24 weeks after EOT (FU24) and 1, 2 and 3 (FU144) years post‐treatment by transient liver elastography (L‐TE) and point shear wave elastography (pSWE) using acoustic radiation force impulse (ARFI) of the liver (L‐ARFI) and spleen (S‐ARFI). Biochemical, virological and clinical data were also obtained. Liver stiffness assessed by L‐TE decreased between BL [median (range), 32.5(9.1–75) kPa] and EOT [21.3(6.7–73.5) kPa; p < .0001] and EOT and FU144 [16(4.1–75) kPa; p = .006]. L‐ARFI values improved between EOT [2.5(1.2–4.1) m/s] and FU144 [1.7(0.9–4.1) m/s; p = .001], while spleen stiffness remained unchanged. Overall, L‐TE improved in 38 of 54 (70.4%) patients at EOT and 29 of 38 (76.3%) declined further until FU144, whereas L‐ARFI values decreased in 30/54 (55.6%) patients at EOT and continued to decrease in 28/30 (93.3%) patients at FU144. Low bilirubin and high albumin levels at BL were associated with improved L‐ARFI values (p = .048) at EOT or regression of cirrhosis (<12.5 kPa) by L‐TE at FU144 (p = .005), respectively. Liver stiffness, but not spleen stiffness, continued to decline in a considerable proportion of patients with advanced liver disease after HCV eradication.

Immunosuppression by inhibition of the mechanistic target of rapamycin (mTOR) is a promising approach after liver transplantation. The mTOR inhibitor sirolimus was used in selected liver graft recipients despite safety concerns and lack of approval. Everolimus is another mTOR inhibitor approved after liver transplantation. It is currently unknown, whether conversion of sirolimus to everolimus is safe in long-term liver graft recipients. Long-term liver graft recipients treated with sirolimus were converted to everolimus. A systematical analysis of biochemical and clinical data before and after conversion was performed. Sixteen patients were included (female/male, 8/8). Median (range) age at conversion was 66 years (49-78 years), and patients were converted at a median (range) of 10.1 years (4.0-22.3 years) after liver transplantation. In the majority of patients, no dose adjustment was needed after conversion. No rejection and no cytomegalovirus replication episodes were observed. Furthermore, no differences were found with respect to kidney function, diabetes mellitus, or blood pressure before and after conversion. Bilirubin serum concentration was lower, whereas aspartate aminotransaminase, alanine aminotransferase, and triglycerides serum concentrations were higher after conversion to everolimus. Neither clinical- nor graft-associated significant complications were observed after conversion from sirolimus to everolimus in long-term liver graft recipients. Everolimus-based immunosuppression may be offered to patients after liver transplantation formerly treated with sirolimus.
