Background and Aim The impact of hepatitis C virus (HCV) clearance by direct‐acting antiviral agents (DAAs) on HCV‐related extrahepatic manifestations is not well known. We evaluated the effect of viral clearance on metabolic and renal parameters. Methods In this prospective study, HCV patients who achieved a sustained virologic response (SVR) by DAAs were evaluated before, at the end, and 24 weeks after treatment for glycemic (serum glucose and insulin, HOMA‐IR, HOMA‐β, and HOMA‐S) and lipid (serum cholesterol, triglycerides, low‐density lipoprotein [LDL], high‐density lipoprotein) metabolism and renal function (serum creatinine, estimated glomerular filtration rate [eGFR]). Results A total of 343 consecutive HCV patients were evaluated. At 24 weeks of post‐follow‐up, an increase in body mass index (BMI) was observed (P, In a prospective study, 343 patients with hepatitis C virus (HCV) infection who achieved sustained virologic response by direct‐acting antiviral agent (DAA) treatments were followed up for 24 weeks to evaluate the impact of viral clearance on metabolic and renal parameters. HCV clearance was independently associated with a significant reduction in serum glucose, HOMA‐IR, and HOMA‐β and an increase in HOMA‐S. Furthermore, an increase in serum cholesterol and low‐density lipoprotein cholesterol levels was observed. Renal function was improved with a significant decrease in serum creatinine levels and an increase in estimated glomerular filtration rate. Data show that HCV clearance by DAA induces significant changes in metabolic and renal parameters.

Recently, several cases of symptomatic, sometimes fatal bradycardia during the first days of direct-acting antiviral (DAA) (eg, sofosbuvir [SOF]) administration have been reported. We analyzed in detail electrocardiographic (ECG) changes during SOF- or non-SOF-based chronic hepatitis C (CHC) treatment, specifically focusing on bradyarrhythmias. All 39 consecutive patients treated at our center with any interferon-free regimen between June and December 2015 were included in this study (26 SOF-based therapy vs 13 no-SOF interferon-free regimens). ECG tracings were obtained from all patients the first day of treatment and after 7, 14, and 28 days. ECG parameters (P-wave, QRS, QT interval, JT interval, Tapex -Tend interval duration) were compared between the 2 groups at baseline and at the 3 different time points during antiviral therapy. There were no cases of symptomatic bradycardia/syncope. In the SOF group, QTc duration rose after 1 week (from 424.3 to 431.2 milliseconds; P = .013) and returned to baseline during therapy. QT dispersion dropped since week 1 (from 85.6 to 67.2 milliseconds) and remained significantly reduced until the end of the observation period (72.9 msec) (P = .003). JT dispersion reduced up to week 2 (P = .010) and returned to baseline at week 4; in the no-SOF group, QRS dispersion transiently reduced (from 41 to 34.5 milliseconds, day 7). No other significant changes were observed in the remaining parameters. In CHC patients treated with SOF and other DAAs, ECG parameter changes were mild and/or transient and did not translate into clinically significant electrophysiological effects in the absence of amiodarone coadministration.

Aims Diabetic retinopathy (DR) represents the main cause of blindness among adults in the industrialized Countries. Use of telemedicine could offer an easy, smart specialist fundus oculi examination, as well as putting in a screening programme many patients who otherwise would be excluded. Materials and methods The NO BLIND is a transversal, multicentre, observational study. Its pilot phase involved nine public outpatient clinics for 6 months. As endpoint of the study, we assessed the prevalence of DR by retinography in a subset of the Italian population. Patients' fundus oculi photos were performed by trained diabetologists through a digital smart ophthalmoscope. Results According to our endpoint, in the final study population (n = 1461), obtained excluding patients for whom retinography was not able to provide any diagnosis, DR prevalence was equal to 15.5%. According to the receiver operating characteristic (ROC) curve performed, we can observe how retinography appears a highly accurate method to detect DR (AUROC 0.971, 95% confidence interval, 0.954-0.989), with a specificity of the 100% and a sensitivity of the 94.3%. Conclusions Our findings, in an Italian setting, confirm main data in the literature about DR prevalence. Hence, telemedicine could represent an accurate, fast, and cheap method for screening of DR.
