Schistosomiasis of liver graft as a differential diagnosis of abnormal liver tests after transplantation: report of two cases

ABSTRACT Schistosomiasis is a major health problem that affects over 200 million people worldwide. There are few reports of Schistosoma mansoni found in liver transplants as well as scarce information about the course of the disease and the long-term effects on the graft. Herein, we report two cases of schistosomiasis in liver transplant recipients who presented abnormal serum liver enzymes, with evidence of gradual improvement after antiparasitic treatment. Furthermore, we discuss the possible role of screening the parasite infection in potential liver transplant recipients from endemic areas.

Treatment of Hepatitis C with Direct-Acting Antivirals does not Induce Significant Arrhythmias

Abstract Background Chronic Hepatitis C (CHC) therapy with direct-acting antivirals (DAAs) has high efficacy and safety, but some cases of bradyarrhythmias have been described. Objective To evaluate heart rhythm disorders during DAA treatments. Methods Forty-eight patients with CHC (mean 61 years of age; 56% males; 73% HCV genotype 1) were evaluated before and during treatment with DAAs, analyzed by a resting 12-lead ECG [PR, QRS, and QT corrected (QTc) intervals measured] and a 24-h-Holter system, to evaluate the heart rate (HR) and the occurrence of arrhythmias. The Student's t-test or the Wilcoxon-Mann-Whitney test for continuous, independent variables were performed with a statistically significant p-value < 0.05. Results The electrocardiographic parameters before and during treatment were: PR interval (147.2 ± 15.6 vs 144.9 ± 15.6 ms; p = 0.21), QTc interval (427 ± 22.3 vs 421.7 ± 25.3 ms; p = 0.24), minimum HR (52.7 ± 8.4 vs 53.2 ± 8.5 bpm; p = 0.49), median HR (74.2 ± 10.4 vs 75.2 ± 9 bpm; p = 0.83), and maximum HR (117.4 ± 16.8 vs 117.9 ± 16.3 bpm; p = 0.25). These parameters proved to be similar among 11 beta-blockers or 22 ribavirin users. During treatment, the 21 cirrhotic patients presented significantly lower median HRs (72.1 ± 9.0 vs 77.9 ± 8.2 bpm; p = 0.02) and maximum HRs (108.9 ± 15.2 vs. 125.1 ± 13.2 bpm, p < 0.0001) through a 24-h-Holter monitoring than the patients without cirrhosis. No clinically relevant arrhythmias were detected. Conclusion DAAs do not significantly influence heart rate or induce significant cardiac arrhythmias in patients with CHC.
