BACKGROUND & AIMS: Vitamin D deficiency is an important complication of chronic intestinal failure (CIF). Liver steatosis is a known late complication of long-term home parenteral nutrition (HPN) therapy in patients with CIF, which can progress to intestinal failure-associated liver disease (IFALD). The aim of this study was to determine the prevalence of vitamin D deficiency among Slovene HPN patients and determine any potential correlation between serum vitamin D levels and liver steatosis associated with IFALD in adult patients with CIF on HPN therapy.
METHODS: Adult patients, diagnosed with CIF, receiving long term HPN therapy, were included in a cross-sectional study. Vitamin D status was determined by measuring serum levels of 25-hydroxyvitamin D. The presence of liver steatosis was diagnosed using 3 T S MRI scanner. The association between serum vitamin D levels and liver steatosis was calculated using univariate logistic regression.
RESULTS: We included 63 adult patients with CIF on HPN therapy in the study. The median duration of HPN therapy was 70 weeks. The average serum concentration of 25-hydroxyvitamin D was 41.3 nmol/l. Insufficient vitamin D levels were found in 45 (73%) patients. Liver steatosis was present in 18 (28.6%) patients. No statistically significant association between serum vitamin D levels and liver steatosis in the study population was found.
CONCLUSION: The results of this study have shown a high prevalence of vitamin D deficiency in adult patients with CIF on HPN. We failed to demonstrate an association between serum vitamin D levels and the prevalence of liver steatosis.
