Acute-on-Chronic Liver Failure: Causes, Clinical Parameters, and Predictors of Mortality

Objectives This study aimed to identify the causes, clinical characteristics, and 28-day in-hospital mortality predictors in patients with acute-on-chronic liver failure (ACLF). Methods A cross-sectional study enrolled sixty-four patients aged 18-70 years with acute-on-chronic liver failure. The study was conducted at the Gastroenterology Department, Lahore General Hospital. The study classified ACLF according to the criteria of the European Association for the Study of the Liver - Chronic Liver Failure (EASL-CLIF). Patients were followed for 28 days for mortality outcomes. The outcomes between Survivor and Non-survivor groups were compared using the Chi-Square/Fisher's Exact Test for categorical variables and the Mann-Whitney U test for continuous variables. Results In this study, age and duration of chronic liver disease were not significantly different between survivors and non-survivors. The etiology of liver disease and ACLF causes had no impact on 28-day mortality. Non-survivors had lower mean arterial pressure, and higher mortality was linked with lower Glasgow Coma Scale scores, upper gastrointestinal bleeding, and Grade IV hepatic encephalopathy. Significant differences in bilirubin, serum creatinine, urea, and C-reactive protein levels were observed at 28 days. Survival rates were highest with single organ failure (35.94%) and decreased with multiple organ failures. The overall survival rate was 51.56%. Predictive validity for mortality was assessed using the Area Under the Curve (AUC), with Child-Turcotte-Pugh (CTP) at 0.679, Model for End-Stage Liver Disease (MELD) at 0.819, and Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) at 0.771. Conclusion This study concludes that in acute-on-chronic liver failure, factors like age, gender, and disease etiology do not significantly predict 28-day mortality. Key mortality indicators include clinical parameters such as lower Glasgow Coma Scale scores, hepatic encephalopathy Grade IV, and laboratory findings like elevated bilirubin and serum creatinine. The MELD score is the most compelling prognostic tool.

Acute-on-Chronic Liver Failure From Acquired Hemochromatosis in a Patient With Sickle Cell Disease

Late presentations of liver failure were previously rare in clinical practice given the high mortality of sickle cell disease (SCD) and shorter life expectancy compared to the general population. With advancements in therapeutics for SCD, patients with SCD have increased lifespans, and with them, patients are placed at increased risk for differing patterns of chronic and end-organ failures. We describe a case of an elderly patient who had multiple chronic complications from her years of SCD, including end-stage renal disease (ESRD) on hemodialysis, acquired hemochromatosis, cirrhosis, and pulmonary hypertension. During this presentation for shortness of breath, she developed acute-on-chronic liver failure (ACLF) with a significant lower gastrointestinal bleed and hemorrhagic shock. Her family ultimately elected to pursue comfort care measures, and she passed later that day.

Dangerous Placebo During the COVID-19 Pandemic: A Series of Homoeopathic Arsenicum Album-Induced Liver Injury

Complementary and alternative medicines were promoted as health supplements, "immune-boosters" and COVID-19 preventive drugs through visual, print, and social media, during the pandemic. In this context, specifically in India, the homeopathic remedy, Arsenicum Album 30C prepared from arsenic trioxide was widely prescribed and publicly supplied through government agencies among adults and school-going children. Inorganic arsenic, known as the "king of poisons" is a highly toxic substance with the potential to cause acute as well as chronic injury to multiple organ systems, mainly skin, lung, liver, and kidneys. Acute liver injury due to arsenic-containing formulations is seldom reported. We present three cases of acute liver injury, leading to death in one patient with underlying non-alcoholic steatohepatitis (NASH) cirrhosis, after consumption of the homeopathic remedy AA30 for COVID-19 prevention.
