Persistent vitamin D deficiency linked with poor clinical liver outcomes
A severe vitamin D deficiency at the time of a primary sclerosing cholangitis (PSC) diagnosis that remains persistent is associated with liver-related mortality or the need for liver transplantation, according to a study.
Researchers analyzed the vitamin D levels of 354 patients diagnosed with PSC at a liver disease clinic.
Overall, 63 patients were found to have severe vitamin D deficiency, defined as <25 nmol/L. These patients were 2.5 times more likely to experience hepatobiliary malignancies. A severe vitamin D deficiency at diagnosis and persistent deficiencies over time were independently associated with a higher risk of poor clinical liver outcomes.
