Sofosbuvir/Simeprevir combination is an effective and well tolerated regimen for patients with chronic HCV genotype IV.

DAAs are safe and effective in genotype 4 chronic HCV patients. It improves liver necro-inflammatory markers in cirrhotics and non-cirrhotics. Cirrhotic patients require careful observation being more vulnerable for treatment related complications.

Background and Aims This study aimed to assess the safety and efficacy of sofosbuvir (SOF)‐based regimens in patients with moderate to severe renal impairment; a subject which has been questioned by many investigators with conflicting results. Methods This is a real‐life multicentre retrospective cohort study on 4944 chronic Hepatitis C virus (HCV) patients with chronic kidney disease (CKD) (eGFR <60 mL/min/1.73 m2) who received SOF‐based therapy in specialized treatment centres affiliated to the National Committee for the Control of Viral Hepatitis in Egypt. The efficacy and safety of SOF‐based regimens was assessed. Results Week 12 virological response rates were 97.5%, 96.7%, 85.7% and 80% in the total cohort, patients with eGFR <30 mL/min/1.73 m2, patients with associated hepatic decompensation and patients on dialysis respectively. Various treatment regimens did not statistically affect the response rates. Treatment experience, cirrhosis and diabetes were predictors of treatment failure on multivariate analysis. Serious adverse events occurred in 0.1% of cases. Forty patients (0.8%) discontinued treatment. Conclusion Sofosbuvir‐based regimens are effective and safe for treating patients with chronic HCV and moderate to severe CKD, and in those with associated hepatic decompensation.

Background and aims Albumin infusion reduces the incidence of postparacentesis circulatory dysfunction among patients with cirrhosis and tense ascites compared with no treatment. Less costly treatment alternatives such as vasoconstrictors have been investigated, but the results are controversial. Midodrine, an oral α1-adrenergic agonist, increases effective circulating blood volume and renal perfusion by increasing systemic and splanchnic blood pressure. Our aim is to assess whether or not morbidity in terms of renal dysfunction, hyponatremia, systemic, or portal hemodynamics derangement or mortality differed in patients receiving albumin versus midodrine. Patients and methods Seventy-five patients with cirrhosis and refractory ascites were randomized to receive albumin infusion, oral midodrine for 2 days, or oral midodrine for 30 days after therapeutic large volume paracentesis (LVP). The primary endpoints were development of renal impairment or hyponatremia, change in systemic and portal hemodynamics, cost, and mortality in the short-term and long-term follow-up. Results No significant difference was found between groups in the development of renal impairment, hyponatremia, or mortality 6 and 30 days after LVP. A significant increase in 24-h urine sodium excretion was noted in the midodrine 30-day group. Renal perfusion improved significantly with the midodrine intake for 30 days only. The cost of midodrine therapy was significantly lower than albumin. Conclusion Midodrine is as effective as albumin in reducing morbidity and mortality among patients with refractory ascites undergoing LVP at a significantly lower cost. Long-duration midodrine intake can be more useful than shorter duration intake in terms of improvement of renal perfusion and sodium excretion.

Background We evaluated the validity of some non-invasive scores and ultrasound findings to predict fibrosis and steatosis in a cohort of NAFLD patients who underwent liver biopsy. Ninety-seven NAFLD patients were enrolled and classified into NASH (66) and simple steatosis groups (31) based on liver biopsy. ROC curves were constructed for Fibrosis-4 index (FIB4), aspartate aminotransferase to platelet ratio index (APRI), and NAFLD fibrosis score (NFS) in fibrosis prediction, also for (hepatic steatosis index; HSI, fatty liver index; FLI) and ultrasonographic subcutaneous and visceral adipose tissue measurements (SAT and VAT) for steatosis prediction. Results FIB4 had AUC of 0.6, APRI and NFS at cutoffs of 0.3 and -.2.4 had AUC of 0.64 and 0.63 in detecting the presence of any grade of fibrosis, and of (0.52, 0.55, and 0.58) for significant fibrosis. FIB4 at a cut-off of (0.76) had the highest AUC in detecting any grade of fibrosis in the simple steatosis group (0.81). SAT (at cutoff of 2.1 and 2.5) was superior to VAT. HSI (at cutoff 45.35 and 45.7) was superior to FLI in detecting moderate or marked steatosis. Conclusion FIB4 and NFS can be used in screening for silent liver disease with ongoing fibrosis in simple steatosis. They are unsatisfactory predictors for significant fibrosis in NAFLD. SAT is better than VAT in predicting moderate steatosis and is slightly better than biochemical HSI.

Progression of recurrent hepatitis C is accelerated in liver transplant (LT) recipients. Direct-acting antivirals (DAAs) have recently emerged as a promising therapeutic regimen for the treatment of hepatitis C virus infection. Rates of sustained virological response (SVR) have drastically improved since the introduction of DAAs. The aim is to elucidate the changes in liver stiffness measurement (LSM) by transient elastography (TE) as well as acoustic radiation force impulse (ARFI) elastography and fibrosis scores after DAA treatment in LT recipients with hepatitis C virus recurrence. A single-center, prospective study including 58 LT recipients with hepatitis C recurrence who received different sofosbuvir-based treatment regimens. Transient elastography and ARFI elastography values were recorded as well as fibrosis 4 score (FIB-4) and aspartate aminotransferase-to-platelet ratio index were calculated at baseline and SVR at week 24 (SVR24). The outcome was improvement in LSM and at least a 20% decrease in LSM at SVR24 compared with baseline. The sustained virological response was 98.1%. There was improvement of platelet counts, alanine aminotransferase, and aspartate aminotransferase, which in turn caused improvement in fibrosis scores at SVR24. LSM by TE and ARFI elastography decreased from the baseline median value of 6.3 kPa (interquartile range [IQR]; 4.6 to 8.8 kPa) and 1.28 m/s (IQR; 1.07 to 1.53 m/s) to an SVR24 median value of 6.2 kPa (IQR; 4.85 to 8.9 kPa) and 1.12 (IQR; 0.97 to 1.30 m/s), respectively. Logistic regression analysis showed that baseline viral load was the only significant predictor of improvement in LS after DAA therapy at SVR24. Sofosbuvir-based treatment resulted in an early improvement in parameters of liver fibrosis in post-LT patients with hepatitis C recurrence.
