Abstract
Background and AimsTotal pancreatectomy with islet autotransplantation (TPIAT) can relieve pain for individuals with acute recurrent or chronic pancreatitis. However, TPIAT may increase the risk of poor nutritional status with complete exocrine pancreatic insufficiency, partial duodenectomy, and intestinal reconstruction. Our study's objective was to evaluate nutritional status, anthropometrics, and vitamin levels before and after TPIAT. MethodsThe multicenter Prospective Observational Study of TPIAT (POST) collects measures including vitamins A, D, and E levels, pancreatic enzyme dose, and multivitamin (MVI) administration before and 1-year after TPIAT. Using these data, we studied nutritional and vitamin status before and after TPIAT. Results348 TPIAT recipients were included (68% adult, 37% male, 93% Caucasian). In paired analyses at 1-year follow-up, vitamin A was low in 23% (vs 9% pre-TPIAT, p < 0.001); vitamin E was low in 11% (vs 5% pre-TPIAT, p = 0.066), and 19% had vitamin D deficiency (vs 12% pre-TPIAT, p = 0.035). Taking a fat-soluble multivitamin (pancreatic MVI) was associated with lower risk for vitamin D deficiency (p = 0.002). Adults were less likely to be on a pancreatic MVI at follow-up (34% vs 66% respectively, p < 0.001). Enzyme dosing was adequate. More adults versus children were overweight or underweight pre- and post-TPIAT. Underweight status was associated with vitamin A (p = 0.014) and E (p = 0.02) deficiency at follow-up. ConclusionsPrevalence of fat-soluble vitamin deficiencies increased after TPIAT, especially if underweight. We strongly advocate that all TPIAT recipients have close post-operative nutritional monitoring, including vitamin levels. Pancreatic MVIs should be given to minimize risk of developing deficiencies.
