Acute Tubular Necrosis Following Interferon-Based Therapy for Hepatitis C: Case Study with Literature Review

Background/Aims: Interferon treatment of malignant or viral diseases can be accompanied by various side-effects including nephro-toxicity. Methods: We report on a 68-year-old Caucasian male who received dual therapy with pegylated interferon 2a plus ribavirin for chronic hepatitis C. Results: After three months of antiviral therapy, the patient developed acute kidney failure (serum creatinine up to 6 mg/dL) with mild proteinuria (500 mg daily) and haematuria. Immediate immunosuppressive therapy with high-dose intravenous steroids did not improve kidney function. Kidney biopsy was consistent with acute tubular necrosis without glomerular abnormalities. He started long-term peritoneal dialysis (four regular exchanges) to provide both dialysis adequacy and ascites removal. Kidney function gradually improved over the following months (serum creatinine around 2 mg/dL) and peritoneal dialysis was continued with two exchanges daily. The temporal relationship between the administration of the drug and the occurrence of nephro-toxicity, and the absence of other obvious reasons for acute tubular necrosis support a causative role for pegylated interferon; benefit on kidney disease was noted after withdrawal of antiviral agents. An extensive review of the literature on acute tubular necrosis associated with interferon-based therapy, based on in vitro data and earlier case-reports, has been made. The proposed pathogenic mechanisms are reviewed. Conclusions: Our case emphasizes the importance of monitoring renal function during treatment of chronic hepatitis C with antiviral combination therapy as treatment may precipitate kidney damage at tubular level

Accuracy, Reliability, and Comprehensiveness of ChatGPT-Generated Medical Responses for Patients With Nonalcoholic Fatty Liver Disease

: Nonalcoholic fatty liver disease (NAFLD) is an increasing global health problem and is expected to become the leading indication for liver transplantation.1 There are no approved NAFLD-specific pharmacotherapies, and lifestyle modification is the primary recommended therapy.2 Innovative approaches to facilitate the implementation and long-term maintenance of lifestyle changes are needed to address the challenging and complex nature of the management of NAFLD, which recently was renamed as metabolic dysfunction-associated steatotic liver disease, to overcome the limitations and stigma of the previous name.3,4 Artificial intelligence (AI)-powered chatbots have been shown to provide effective personalized support and education to patients, with the potential to complement health care resources. The OpenAI Foundation's AI chatbot, Chat Generative Pretrained Transformer (ChatGPT), has attracted worldwide attention for its remarkable performance in question-answer tasks.5-7 This study evaluated the accuracy, completeness, and comprehensiveness of chatGPT's responses to NAFLD-related questions, with the aim of assessing its performance in addressing patients' queries about the disease and lifestyle behaviors

Ribavirin Impairs Salivary gland function During Combination Treatment With Pegylated Interferon Alfa-2a In HEpatitis C patients

Background: Xerostomia is a common adverse event of unknown etiology observed during pegylated interferon (PegIFN)/Ribavirin (Rbv) treatment. Objectives: To assess the frequency and mechanisms of xerostomia during PegIFN/Rbv therapy. Patients and Methods: Thirty-one naive patients with chronic hepatitis C consecutively received PegIFN-alpha 2a (180 mu g/week) plus Rbv (800-1200 mg/day). The controls were 10 patients with chronic hepatitis B who received PegIFN-alpha 2a (180 mu g/week). During treatment and follow-up, all patients underwent basal and masticatory stimulated sialometry, otorhinolaryngoiatric (ORL) examination, and a questionnaire survey to subjectively assess symptoms of oral dryness. Results: Twenty-seven patients on PegIFN/Rbv and 4 on PegIFN (87% vs. 40%, P = 0.006) reported xerostomia. Thirty patients on PegIFN/Rbv combination therapy and 2 patients on monotherapy had ORL signs of salivary gland hypofunction (97% vs. 20%, P < 0.0001). Mean basal (A) and stimulated (B) salivary flow rates (mL/min) progressively decreased during PegIFN/Rbv treatment (A, 0.49 at baseline vs. 0.17 at the end of treatment, P < 0.0001; B,1.24 at baseline vs. 0.53 at the end of treatment, P = 0.0004). At week 24 following PegIFN/Rbv treatment, salivary flow rates were similar to baseline (A, 0.53 at the end of follow-up vs. 0.49 at baseline; B,1.19 at the end of follow-up vs. 1.24 at baseline). Salivary function was unaffected in monotherapy patients. Conclusions: Rbv causes salivary gland hypofunction in hepatitis C patients receiving PegIFN/Rbv therapy, which promptly reverts to normal upon cessation of treatment

Mediterranean Diet and NAFLD: What We Know and Questions That Still Need to Be Answered

open8Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and is expected to become the leading cause of end-stage liver disease worldwide over the next few decades. In fact, NAFLD encompasses different clinical scenarios, from the simple accumulation of fat (steatosis) to steatohepatitis (NASH), NASH-cirrhosis, and cirrhosis complications. In this context, it is fundamental to pursue strategies aimed at both preventing the disease and reducing the progression of liver fibrosis once liver damage is already initiated. As of today, no pharmacological treatment has been approved for NAFLD/NASH, and the only recommended treatment of proven efficacy are life-style modifications, including diet and physical exercise pointing at weight loss of 5%-7%. Different dietetic approaches have been proposed in this setting, and in this review, we will discuss the evidence regarding the efficacy of the Mediterranean Diet as a treatment for NAFLD. In particular, we will report the effects on liver-related outcomes.openPlaz Torres, Maria Corina; Aghemo, Alessio; Lleo, Ana; Bodini, Giorgia; Furnari, Manuele; Marabotto, Elisa; Miele, Luca; Giannini, Edoardo GPlaz Torres, Maria Corina; Aghemo, Alessio; Lleo, Ana; Bodini, Giorgia; Furnari, Manuele; Marabotto, Elisa; Miele, Luca; Giannini, Edoardo

Hepatitis C virus treatment in the real world: optimising treatment and access to therapies

Chronic HCV infections represent a major worldwide public health problem and are responsible for a large proportion of liver related deaths, mostly because of HCV-associated hepatocellular carcinoma and cirrhosis. The treatment of HCV has undergone a rapid and spectacular revolution. In the past 5 years, the launch of direct acting antiviral drugs has seen sustained virological response rates reach 90% and above for many patient groups. The new treatments are effective, well tolerated, allow for shorter treatment regimens and offer new opportunities for previously excluded groups. This therapeutic revolution has changed the rules for treatment of HCV, moving the field towards an interferon-free era and raising the prospect of HCV eradication. This manuscript addresses the new challenges regarding treatment optimisation in the real world, improvement of antiviral efficacy in `hard-to-treat' groups, the management of patients whose direct acting antiviral drug treatment was unsuccessful, and access to diagnosis and treatment in different parts of the world

HBV and HCV Therapy

One year of interferon therapy inhibits HBV replication in one third of the patients whereas long-term administration of oral nucleos(t)ide analogues is efficient in most of them, as long as early treatment adaptation in patients with partial virological response and resistance is provided. Following the demonstration of a more potent antiviral effect in terms of sustained virological response (SVR) rates, Pegylated-IFN coupled with Ribavirin has become the standard treatment for chronic hepatitis C, with nearly 65% of all treated patients achieving a SVR. Long-term suppression of HBV and eradication of HCV would halt the progression of chronic hepatitis to cirrhosis, hepatocellular carcinoma and liver decompensation
