Background And Aims:
Primary sclerosing cholangitis (PSC) is an autoimmune chronic cholestatic liver disease causing inflammation, fibrosis, and increased risk of cholangitis, cirrhosis, and hepatobiliary cancers. How PSC affects patient-reported quality of life (QoL) is sparsely studied. We aimed to investigate the impact of PSC on QoL.
Methods:
This cross-sectional study included 101 patients with PSC. We investigated QoL using the PSC-specific PSC patient-reported outcome (PRO) instrument, the generic health-related QoL questionnaire EQ-5D-5L, and the fatigue visual analog scale (VAS) score. We also investigated associations between QoL and noninvasive inflammation and fibrosis measures; the macrophage marker soluble (s)CD163, fibrosis-4 score, and transient elastography.
Results:
The median age was 45 years, 65% were males, 10% had PSC with autoimmune hepatitis overlap disease, and 92% had inflammatory bowel disease. Eighty-five patients completed all QoL questionnaires and reported high QoL across all PSC PRO instrument items and EQ-5D-5L. sCD163 correlated modestly with PSC PRO total score (rho = 0.28) and fatigue VAS score (rho = 0.26) but not EQ-5D-5L. Patients with any previous episode of cholangitis reported lower QoL than cholangitis-naive patients on the PSC PRO score (21 vs 15, P = .04) and EQ-5D-5L VAS score (71 vs 86, P = .01). There was no association between noninvasive markers of liver fibrosis and QoL.
Conclusion:
In this cohort, patients with PSC reported high QoL. The PSC PRO score correlated with sCD163 and was sensitive to cholangitis episodes, validating the instrument as a true PSC-specific QoL tool.

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...
