Abstract:
Given the unmet need of fatigue in primary biliary cholangitis (PBC), the PBC working group of the European Reference Network for Rare Liver Diseases assessed and summarised the current evidence relating to fatigue in PBC to provide guidance for clinical practice and identify knowledge gaps to shape the future research agenda. Six key questions regarding PBC-related fatigue were summarised through systematic review and meta-analyses. Fatigue is highly prevalent in PBC and substantially affects health-related quality of life. Several measurement tools are available but future research should emphasise longitudinal designs to track symptoms with easy-to-apply and accurate tools. The pathophysiology of fatigue in PBC remains largely unknown and involves a complex interplay of various factors. Pilot studies suggest the effectiveness of non-pharmacological treatments, which warrant further investigation. Pending the results of clinical trials, no pharmacological treatment can be recommended for PBC-related fatigue. Finally, we introduce a practical, three-step ASK-MEASURE-TREAT algorithm that can be applied in all patients with PBC.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
