Extremely rare complication in high-risk newborn on long-term parenteral nutrition and large stool losses through ileostomy.

Aim: To analyse postnatal characteristics, clinical and laboratory findings, results of investigations in the newborn (25 gestational weeks; Apgar score: 6/9 points; born per caesarean section; birth weight: 600 g; birth length: 31 cm; head circumference: 21 cm) from the first high-risk pregnancy with acquired form of acrodermatitis enteropathica.

Results: After summarizing the clinical picture with laboratory findings, we analysed the components of parenteral nutrition with regard to the deficiency of trace elements and vitamins. The zinc depletion dominated.

Conclusion: The diagnosis is clinical, based on the presence of a typical clinical picture together with a low serum zinc concentration. Standard preparations with elementary elements do not sufficiently cover the daily needs of children, other possibilities of supplementation in intravenous form are not available. It is necessary to supplement zinc in premature children, in children with high losses of zinc (with diarrhoea, in patients with a stoma, in patients with severe skin disease) (Fig. 4, Ref. 15).
