Section of Gastroenterology

Background and aims: Acute-on-chronic liver failure (ACLF) is considered a main prognostic event in patients with chronic liver disease (CLD). We analyzed the 28-day and 90-day mortality in ACLF patients with or without underlying cirrhosis enrolled in the ACLF Research Consortium (AARC) database.
Methods: A total of 1,621 patients were prospectively enrolled and 637 (39.3%) of these patients had cirrhosis. Baseline characteristics, complications and mortality were compared between patients with and without cirrhosis.
Results: Alcohol consumption was more common in cirrhosis than non-cirrhosis (66.4% vs. 44.2%, p < 0.0001), while non-alcoholic fatty liver disease/cryptogenic CLD (10.9% vs 5.8%, p < 0.0001) and chronic HBV reactivation (18.8% vs 11.8%, p < 0.0001) were more common in non-cirrhosis. Only 0.8% of patients underwent liver transplantation. Overall, 28-day and 90-day mortality rates were 39.3% and 49.9%, respectively. Patients with cirrhosis had a greater chance of survival compared to those without cirrhosis both at 28-day (HR = 0.48; 95% CI 0.36-0.63, p < 0.0001) and 90-day (HR = 0.56; 95% CI 0.43-0.72, p < 0.0001), respectively. In alcohol CLD, non-cirrhosis patients had a higher 28-day (49.9% vs. 23.6%, p < 0.001) and 90-day (58.4% vs. 35.2%, p < 0.001) mortality rate than cirrhosis patients. ACLF patients with cirrhosis had longer mean survival than non-cirrhosis patients (25.5 vs. 18.8 days at 28-day and 65.2 vs. 41.2 days at 90-day). Exaggerated systemic inflammation might be the reason why non-cirrhosis patients had a poorer prognosis than those with cirrhosis after ACLF had occurred.
Conclusions: The 28-day and 90-day mortality rates of ACLF patients without cirrhosis were …

Malnutrition And Liver Disease In A Developing Country, Asra Tus Saleha Siddiqui, Om Parkash, Syeda Amrah Hashmi

Section of Gastroenterology

Malnutrition is a highly prevalent and under recognized condition in developing countries of South Asia. The presence of malnutrition causes a severe impact on patients with liver cirrhosis. The etiology of cirrhosis differs in the South Asian region compared to the West, with hepatitis B and C still being the leading causes and the prevalence of nonalcoholic fatty liver disease increasing over time. Comorbid malnutrition worsens outcomes for cirrhosis patients. Urgent attention to address malnutrition is needed to improve patient outcomes. The etiology and pathophysiology of malnutrition in liver diseases is multifactorial, as reduction in liver function affects both macronutrients …

Perception Of Non-Alcoholic Fatty Liver Disease: Real-Life Experience From Pakistan, Nazish Butt, Muhammad Ali Khan, Lajpat Rai, Riaz Hussain Channa, Hanisha Khemani, Amanullah Abbasi

Section of Gastroenterology

Introduction: Non-alcoholic fatty liver disease (NALFD) has become one of the most pervasive causes of hepatic pathology. Because of its marked association with metabolic syndrome, type II diabetes and cardiovascular disease, NAFLD has gained substantial focus recently. Its prevalence and incidence are on the rise in Pakistan. However, due to its indolent and mostly asymptomatic course, NAFLD is often overlooked. This reckless behavior towards a potentially deadly disease is influenced most notably by disinformation or flawed perception, although there are a number of other complex socioeconomic components to this as well. With respect to NAFLD, the gap between disease understanding …

Rapid Development Of Hepatocellular Carcinoma After Eradication Of Hepatitis C Virus With Directly Acting Antiviral Treatment, Fakhar Ali Qazi Arisar, Saeed Hamid

Section of Gastroenterology

Hepatitis C is a major risk factor for the development of hepatocellular carcinoma (HCC), arising typically on a background of liver cirrhosis. Treatment of hepatitis C has been revolutionized by the addition of oral direct-acting antivirals (DAAs) with sustained virological response (SVR) rates above 90%. There is a recent concern under debate about the increased risk of early HCC recurrence in patients with chronic hepatitis C who were treated with direct-acting antivirals. Nonetheless, these reports mostly focused on patients who were cirrhotic and were already treated for HCC. We report 4 cases of treatment naive, chronic hepatitis C patients who …

Hepatocellular Carcinoma In Pakistan: Where Do We Stand?, Amna Butt, Zaigham Abbas, Wasim Jafri

Section of Gastroenterology

Context:

From the 1970s till the mid 1990s, hepatitis B was the most common etiological factor for hepatocellular carcinoma (HCC) in Pakistan. Afterwards, a shift in HCC etiology was observed with a steady rise in hepatitis C virus (HCV) related HCC cases. HCV-3a, which is the most prevalent genotype, is also most frequent in HCV related HCC. There was an increase in the proportion of non-B non-C (NBNC) HCC cases as well, which might be attributed to an increase in non-alcoholic fatty liver disease.

Evidence Acquisition:

The age-standardized rate for HCC is 7.64/100 000 in males and 2.8/100 000 in …
