Micronutrient status of children receiving prolonged enteral nutrition.

BACKGROUND AND AIMS: The aim of this study was to assess the micronutrient status of children receiving prolonged enteral nutrition. METHODS: This cross-sectional single-center study included all 64 children (median age 6.8 years) receiving enteral nutrition providing >50% of daily energy intake for more than 6 months (median duration of enteral nutrition 43 months). The characteristics of the patients and mode of enteral nutrition were recorded. The concentrations of iron, zinc, copper, selenium and vitamins A, D, E and C were measured in plasma. RESULTS: Twelve children (19%) had iron deficiency. A high 25-hydroxyvitamin D concentration was recorded in 20% of the children, but none had associated hypercalcemia. Fifty-two children (81%) had low zinc concentrations in both plasma and erythrocytes. Plasma zinc, calcium, phosphorus and vitamin D concentrations were significantly lower in children receiving fiber supplementation. Abnormal micronutrient concentrations were found more frequently in the children receiving fiber supplementation. No other predisposing factors were associated with micronutrient deficiencies. CONCLUSION: Long-term enteral nutrition can lead to micronutrient deficiencies in children, whose micronutrient concentrations may require regular checking. Fiber supplementation might reduce the bioavailability of zinc, calcium, phosphorus and vitamin D.

[Pyoderma gangrenosum with lung involvement treated with infliximab]. / Pyoderma gangrenosum avec localisations pulmonaires traité par infliximab.

BACKGROUND: Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis often associated with systemic diseases, particularly chronic inflammatory bowel diseases. Extracutaneous manifestations (articular, ocular, renal, pulmonary, hepatosplenic, muscular) exist, with lung involvement being the most common. PATIENT AND METHODS: We report a case of PG with skin and lung involvements in a patient treated with high-dose corticosteroids in a setting of severe ulcerative colitis (UC). Lung involvement was diagnosed during the pretreatment assessment performed prior to initiation of anti-TNFα therapy. Infliximab resulted in rapid improvement of the lung and skin lesions. DISCUSSION: In the event of simultaneous cutaneous PG lesions and lung lesions suggestive of abscess, visceral involvement should be suspected. First-line treatment consists of oral corticosteroids. In our patient, the occurrence of lesions under corticosteroids in UC militated in favour of anti-TNFα therapy, which proved effective.
