Fat Soluble Vitamin Assessment and Supplementation in Cholestasis

Malnutrition in children with chronic cholestasis is a prevalent issue and a major risk factor for adverse outcomes. Fat soluble vitamin (FSV) deficiency is an integral feature of cholestatic disease in children, often occurring within the first months of life in those with neonatal cholestasis and malnutrition. This review focuses on FSVs in cholestasis, with particular emphasis on a practical approach to surveillance and supplementation that includes approaches that account for differing local resources. The overarching strategy suggested is to incorporate recognition of FSV deficiencies in cholestatic children in order to develop practical plans for close monitoring and aggressive FSV repletion. Routine attention to FSV assessment and supplementation in cholestatic infants will reduce long periods of inadequate levels and subsequent adverse clinical sequalae.
