The present study suggests that cow's milk protein allergy children have high prevalence of iodine deficiency and poor growth, however the 2 conditions were not associated. The subgroup of mainly breastfed infants was at higher risk of iodine deficiency compared to weaned infants. Subjects with feeding problems had increased risk of malnutrition.

Background & aims: Patients with intestinal failure (IF) are dependent on long-term home parenteral nutrition (HPN) to ensure growth and development. The primary aim of the present study was to assess bone mineral density (BMD) and vitamin D status in paediatric IF patients on HPN and a group of healthy children aged 2e18 years. Secondary aims were to assess growth, body composition, nutrient provision and physical activity. Methods: An observational cross-sectional study was performed at Oslo University Hospital and at the Department of Nutrition, University of Oslo, from January to September 2017. Dual energy x-ray absorptiometry (DXA; Lunar Prodigy in IF patients and Lunar iDXA in healthy subjects) was performed to assess BMD and body composition. BMD z-score (BMDz) was calculated for total body and lumbar spine L2-L4 based on the integrated reference population in the software. Weight and height were measured for growth assessment. Nutrient provision was assessed by a 4-day food record. Blood samples were analysed for 25-hydroxy-vitamin D (25(OH)D) and 1,25-dihydroxyvitamin D (1,25(OH) 2 D). Physical activity was reported by a questionnaire. Results: Nineteen IF patients and 50 healthy children were included. The mean age of participants was 10.0 years. The aetiology of IF patients was paediatric intestinal pseudo-obstruction (58%), short bowel syndrome (26%), and intestinal enteropathy (16%). Lower median BMDz for total body (À0.4 vs 1.1, P < 0.001) and lumbar spine L2-L4 (À0.9 vs 0.2, P ¼ 0.01) were found in the IF group compared with the healthy children. Vitamin D provision was significantly higher in IF patients (17 mg/d vs 5.3 mg/d, P < 0.001). Both groups were sufficient in 25(OH)D (IF patients 71 nmol/L vs healthy 81 nmol/L). Nevertheless, IF patients had significantly lower 1,25(OH) 2 D than healthy children (71 pmol/L vs 138 pmol/L, P < 0.001). The IF group was significantly shorter (height for age z-score À1,5 vs 0,1, P ¼ 0.001) and lighter (weight for age z-score À1,0 vs 0,1, P ¼ 0.009) compared with the healthy subjects.

Our findings imply that most young adults with JA attain the same BMD as healthy subjects if the disease goes into remission, while young adults with active disease have increased risk for osteopenia and osteoporosis.

Objectives:To study micronutrient status and nutritional intake from complementary feeding in children on a cows’ milk exclusion (CME) diet.Methods:Fifty-seven children with cows’ milk allergy, younger than 2 years, were included in a cross-sectional study. Blood was analyzed for micronutrient status. Complementary feeding was defined as all solids and liquids except of breast milk, and assessed by 3-day food diary. The results were analyzed according to 3 feeding patterns: mainly breast-fed (mBF), partially breast-fed, and no breast milk group (nBM).Results:The children had a median age of 9 months and micronutrient status was within normal range for total homocysteine (p-tHcy), s-B12, s-folate, b-Hb, s-ferritin, s-zinc, and s-25(OH)D. There were no significant differences between feedings groups, except for B12-biomarkers. The mBF had higher p-tHcy (P < 0.000) and lower s-B12 (P = 0.002) compared nBM. Vitamin B12 deficiency (p-tHcy >6.5 μmol/L combined with s-B12 <250 pmol/L) was found in 12% of participants, most frequently among the mBF (36%) and none in nBM group (P = 0.009). Vitamin B12 intake from complementary feeding was negatively correlated with p-tHcy (r = −0.479, P = 0.001) and positively with s-B12 (r = 0.410, P = 0.003). Iron deficiency anemia was found in 5%. Iron intake correlated positively with b-Hb (r = 0.324, P = 0.02). Zinc deficiency was found in 7% and low 25(OH)D in 9%. Vitamin D intake was positively correlated with the use of supplements (r = 0.456, P = 0.001).Conclusion:The risk of B12 deficiency was high in mBF infants on CME diet, and complementary feeding was associated with better B12 status. Iron, zinc, and vitamin D deficiencies were present in all feeding groups. Complementary feeding should be introduced at 4 to 6 months of age. Vitamin D supplement is recommended to ensure adequate intake.

Background & aims: Children with intestinal failure (IF) receive parental nutrition to ensure adequate growth and development. The aim of this study was to assess micronutrient status in paediatric IF patients receiving home parenteral nutrition (HPN) in comparison to a group of healthy children. Methods: An observational cross-sectional study was performed at Oslo University Hospital and at the Department of Nutrition, University of Oslo from January to September 2017. All children with IF, aged two to 18 years, were invited to participate. A reference group of healthy children was recruited through social media advertisement. Dietary intake was assessed by a four-day food record, and enteral and parenteral provision was recorded. Blood samples were analysed for vitamins, minerals and haematology to assess iron status. Two spot urine samples from each subject were analysed for iodine concentration (UIC) and creatinine. Results: Nineteen children with IF and 50 healthy children were included. The mean age of the participants was 10.0 years. IF-patients received a median of 76% of their estimated energy requirements from parenteral nutrition (PN). Recommended intake (RI) for iodine from the diet was reached by 16% of IF patients and 28% of healthy children. In the IF group there was a significant positive correlation between UIC and the percentage of iodine intake from oral diet and enteral nutrition support (r ¼ 0.57, p ¼ 0.03). Although the IF patients had a median parenteral iodine supply of more than twice the ESPGHAN recommendation, the median UIC was 89 mg/L indicating insufficient iodine status. This may suggest that the ESPGHAN recommendation for iodine in paediatric parenteral nutrition is too low. The healthy children had sufficient iodine status according to the median UIC (133 mg/L). IF patients had significantly lower total provision of iron compared to the healthy children, 4,9 vs 8,4 mg/day (p ¼ 0.01) with 21% of IF patients and 28% of healthy children reaching RI for iron. The prevalence of anaemia was higher in IF patients than in the healthy children (40 vs.10%, p ¼ 0.016). Conclusion:The study indicates an insufficient iodine and iron status among paediatric IF patients. Iodine status was associated with enteral provision and patients had insufficient status even if they received the ESPGHAN recommendation of iodine.

Objective. Growth abnormalities and poor nutritional status have been reported in children with juvenile idiopathic arthritis (JIA). The aim of this study was to evaluate the impact of juvenile chronic rheumatic disease on current nutritional status in adult patients in remission or with active disease. Methods. One hundred thirty-eight women and 82 men, aged >20 years, with JIA were studied after a mean disease duration of 15.5 ؎ 2.3 years. Eighty-four (61%) of the women and 49 (60%) of the men were in remission. Forty-one healthy women and 54 healthy men served as a reference group. Body composition was analyzed by dual-energy x-ray absorptiometry.Results. There was no difference in height or body mass index (BMI) between patients and healthy subjects. However, female patients with systemic disease had significantly reduced BMI compared with those with pauciarticular JIA (P < 0.001), and female patients who used or had been using corticosteroids had significantly lower weight, height, and BMI compared with the patients who had never used corticosteroids (P < 0.05). Female patients in remission had significantly more lean body mass compared with healthy controls (P < 0.05) and significantly less body fat was found in both women and men (P < 0.01 for both). Patients with active disease had the same amount of lean body mass as the healthy controls, but significantly less body fat (P < 0.05 for women and P < 0.01 for men). Conclusion. Adult patients with JIA had attained normal height, weight, and BMI, with the exception of women with systemic JIA and those who were using or had used corticosteroids. Patients with JIA in remission seemed to have a better nutritional status than healthy subjects.

Objective. To assess the impact of disease activity on acquired peak bone mass and bone turnover in young adult patients with either persistent juvenile arthritis (JA) or a history of JA (JA in remission).Methods. Two hundred twenty-nine patients with JA were studied after a mean ؎ SD of 15.6 ؎ 2.4 years in women and 14.9 ؎ 2.1 years in men since disease onset. One hundred forty-five women and 84 men were over the age of 20 at the time of examination (mean ؎ SD age 24.9 ؎ 2.9 years for women and 25.2 ؎ 3.1 years for men). Forty-one healthy women (mean ؎ SD age 27.4 ؎ 3.1 years) and 55 healthy men (mean ؎ SD age 25.7 ؎ 3.1 years) served as a reference group. Bone mineral density (BMD) was analyzed by dual x-ray absorptiometry. Serum osteocalcin concentrations and urinary concentrations of deoxypyridium (D-Pyd) were measured. Linear regression analyses were performed to evaluate the impact of disease on BMD.Results. Patients with persistent disease had significantly lower BMD compared with healthy subjects (P < 0.001 for women at all measured sites and for men at the femoral neck and total body; P < 0.05 for men at the radius and lumbar spine). Of the patients with a history of JA, only women had significantly lower BMD at the femoral neck and total body (P < 0.05). Patients with persistent JA had significantly more osteopenia and osteoporosis than healthy subjects, while patients with a history of JA had more frequent osteopenia only in the total body. Weight, urinary concentration of D-Pyd, and belonging to the patient group significantly affected BMD at all measured sites in the entire study population, while analysis of all patients found that only the number of months taking corticosteroids significantly affected BMD at all measured sites. However, the impact of the variables differed from site to site.Conclusion. Our findings imply that most young adults with JA attain the same BMD as healthy subjects if the disease goes into remission, while young adults with active disease have increased risk for osteopenia and osteoporosis.

Objectives: This study aimed to describe the impact of allogeneic/haploidentical hematopoietic stem cell transplantation on nutritional status and intake in a group of children aged 2 to 18 years. Methods: In an observational study, data were collected prospectively. Patients were prescribed individual nutritional support by hospital routines. Anthropometrics were measured pre-transplant at hospital admission and weekly from the day of transplant (day 0) until day +28. z scores for weight, height, and BMI were calculated using Norwegian growth references to assess nutritional status. Pre-transplant diet was assessed on the day of hospitalization. Nutrient provision from enteral nutrition (EN = oral and tube) and parenteral nutrition (PN) was assessed by daily records from day +1 until day +28, or previous discharge, and compared with recommendations (RI) from the Nordic Nutrition Recommendations and ESPGHAN guidelines. Total energy intake was presented as the percentage (%) of basal metabolic rate (BMR) calculated by the Schofield equation. Macro-and micronutrient provisions were presented as medians (interquartile range) and the % of RI. Results: Twenty-eight patients, mean age 10.3 years (range 3.5-16.6), were included. Two-thirds (n = 18) had malignant diseases. At admission, mean weight Z-score was −0.3, height z scores −0.7, and BMI Z-score 0.1. Eighteen percent (n = 5) were stunted and 25% (n = 7) had overweight. At admission, 25% (n = 7) had established tube feeding, and 7% (n = 2) also had PN. No significant changes in weight z scores were detected during the studied weeks (P = 0.454). The median daily energy provision was 115% (110-123) of BMR and proteins 1.5 (1.3-1.8) g/kg. EN was provided during a median of 93% of the studied days and provided 21% of the energy. PN was given on a median of 96% of the studied days and provided 79% of energy. RI for vitamins, magnesium, and zinc was met. Provision of copper, iodine, selenium, calcium, and phosphate was below RI. Conclusions: Combined EN and PN providing 115% of BMR and 1.5 g/kg protein ensured stable weight by day +28 and covered RI, except for trace elements and minerals.
