Familial hypolipoproteinemia (FHBL) is characterized by an inherited low plasma level of apolipoprotein B containing lipoproteins. FHBL may be caused by mutations of APOB. Individuals with FHBL typically have intestinal malabsorption and frequently suffer from a deficiency of fat-soluble vitamins. Most mutations that cause FHBL are APOB truncating mutations. Here we describe a patient with FHBL caused by a novel truncating mutation together with a novel missense mutation.

Pediatric Transplantation | Year: 2014

Increased focus on the potential negative side effects of steroid usage in pediatric transplantation has led to steroid minimization or steroid-free transplantation. In this study, we report results after complete steroid avoidance in renal transplantation in the period 1994-2009. We evaluate the effects of complete steroid avoidance on allograft function, BMI, and linear growth. The majority of transplanted children were induced with antithymocyte globulin and immunosuppressed with a calcineurin inhibitor and mycophenolate mofetil. Steroids were given only when rejection occurred or due to comorbidities. Anthropometric data were collected from 65 transplantations in 60 children. Patient survival was 93%; graft survival was 81% after five yr (N = 42) and 63% after 10 yr (N = 16). Acute rejection within the first year of transplantation was 9%. The distribution of the children's BMI before transplantation was normal; the mean BMI-SDS was 0.21 before transplantation, and this value remained stable during the next five yr. Post-transplantation the children demonstrated significant improved growth as the mean height-SDS increased significantly from -1.7 to -1.1. Catch-up growth was most pronounced in the youngest (< six yr). Steroid-free immunosuppression in pediatric renal transplantation is safe and protects against steroid-induced obesity and short stature. © 2013 John Wiley & Sons A/S.

Objective: Eosinophilic oesophagitis (EE) is a clinical entity characterised by a set of symptoms and eosinophilic infiltration of the oesophageal epithelium. Recent reports indicate that EE is increasingly diagnosed in paediatric patients. We aimed to evaluate the epidemiology of paediatric EE in a European population. DESIGN:: Infants and children in the Region of Southern Denmark were prospectively referred for further evaluation of symptoms of gastroesophageal reflux disease (GERD) after treatment failure with a proton pump inhibitor. The evaluation included endoscopy, 24-hour oesophageal pH-metry, histology of oesophageal biopsies, and investigations for food allergy (double-blind, placebo-controlled food challenge, skin prick test, S-IgE antibodies, atopy patch test). Results: Of the 78 referred patients, 28 qualified for a diagnosis of GERD. Six children had >15 eosinophils per high-power field in biopsies from the oesophageal mucosa and qualified for the diagnosis of EE. The median age at diagnosis was 9.6 years. In 4 of the 6 patients, food allergy was confirmed by double-blind, placebo-controlled food challenge. In the Region of Southern Denmark with a paediatric population of 256,164 between 0 and 16 years of age, a yearly incidence of EE of 0.16/10,000 was estimated. Conclusion: We report a European prospective study of EE. It was documented in 6 of 78 patients with symptoms of GERD corresponding to an annual incidence of 0.16/10,000 infants and children. © 2010 by European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.

Objective: Preeclampsia is characterized by disturbed placentation, hypertension, proteinuria, and suppression of plasma renin, angiotensin II, and aldosterone. Regulated activity of tissue serine proteases, prostasin, and matriptase is necessary for normal placental development in mice. Prostasin activates the renal epithelial sodium channel. We hypothesized that preeclampsia is associated with low prostasin expression in placenta and spillover of prostasin into urine across the defect glomerular barrier. Methods: In a cross-sectional study, 20 healthy pregnant women and 20 patients suspected of preeclampsia were included. Plasma and urine was obtained before delivery, and placental biopsies were taken immediately after delivery (mean gestational age: control 39 and preeclampsia 38 weeks). Results: Patients with preeclampsia displayed lower levels of aldosterone in plasma and in spot urine normalized for creatinine (P = 0.0001). Prostasin, matriptase, hepatocyte growth factor activator inhibitor type 1 (HAI-1) and 2, and nexin-1 mRNA abundances were not different in placental tissue between groups. Prostasin mRNA in placenta correlated directly with nexin-1 and HAI-1 mRNA, but not with matriptase mRNA. Plasma prostasin and placental homogenate prostasin and nexin-1 protein levels did not differ between groups. Activated, arginine 614 (Arg614)-cleaved matriptase was not detectable in placentas. Western blotting showed significant elevated levels of prostasin in urine from preeclamptic patients that correlated with urine albumin. Placenta and plasma prostasin did not correlate to aldosterone or placental weight. Conclusion: Preeclampsia is not associated with altered prostasin in placenta or plasma at term, but with increased prostasin in urine. An impact of prostasin-matriptase on placental development is likely to be at the level of activity and not protein abundance. Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved.

INTRODUCTION: The objective of this study was to determine the content of macronutrients in human milk (HM) from mothers who gave birth very prematurely, and to investigate possible associations between macronutrients and certain maternal and infant characteristics. MATERIAL AND METHODS: Mothers of very preterm infants with a gestational age (GA) below 32 weeks expressed milk for analysis two weeks after birth, every second week until discharge, at term, at two, and at four months of corrected age. The milk was analyzed using mid-infrared transmission spectroscopy. RESULTS: A total of 214 mothers delivered 736 HM samples for analysis. Two weeks after birth, protein content varied from 1.06 to 2.96 with a mean of 1.76 g/100 ml HM, and the mean protein content decreased significantly until eight weeks after birth (p < 0.04). Previous breastfeeding experience was associated with a lower protein content (p = 0.04) two weeks after birth. HM from mothers of extremely preterm infants (GA < 28 weeks) had a higher fat and energy content two weeks after birth than infants with a GA of 28- 32 weeks (p = 0.001). CONCLUSION: Protein content in human milk varies considerably between mothers, and decreases within weeks after very preterm birth. Previous breastfeeding experience and low GA were associated with a lower protein and a higher fat and energy content in HM, respectively. Inter-individual differences in human milk content possibly influences nutrition and this raises the question of the need for an individualized approach when fortifying human milk for preterm infants.

OBJECTIVES:: This guideline provides recommendations for the diagnosis and management of suspected cow's-milk protein allergy (CMPA) in Europe. It presents a practical approach with a diagnostic algorithm and is based on recently published evidence-based guidelines on CMPA. DIAGNOSIS:: If CMPA is suspected by history and examination, then strict allergen avoidance is initiated. In certain circumstances (eg, a clear history of immediate symptoms, a life-threatening reaction with a positive test for CMP-specific IgE), the diagnosis can be made without a milk challenge. In all other circumstances, a controlled oral food challenge (open or blind) under medical supervision is required to confirm or exclude the diagnosis of CMPA. TREATMENT:: In breast-fed infants, the mother should start a strict CMP-free diet. Non-breast-fed infants with confirmed CMPA should receive an extensively hydrolyzed protein-based formula with proven efficacy in appropriate clinical trials; amino acids-based formulae are reserved for certain situations. Soy protein formula, if tolerated, is an option beyond 6 months of age. Nutritional counseling and regular monitoring of growth are mandatory in all age groups requiring CMP exclusion. REEVALUATION:: Patients should be reevaluated every 6 to 12 months to assess whether they have developed tolerance to CMP. This is achieved in >75% by 3 years of age and >90% by 6 years of age. Inappropriate or overly long dietary eliminations should be avoided. Such restrictions may impair the quality of life of both child and family, induce improper growth, and incur unnecessary health care costs. Copyright © 2012 by European Society.

Objective: To describe prevalence, prenatal diagnosis and epidemiological data on oesophageal atresia from 23 well-defined European regions and compare the prevalence between these regions. Design: Population-based study using data from a large European database for surveillance of congenital anomalies (EUROCAT) for two decades (1987-2006). Settings: Twenty-three participating registries based on multiple sources of information including information about live births, fetal deaths with gestational age ≥20 weeks and terminations of pregnancy. Patients: 1222 cases of oesophageal atresia in a population of 5 019 804 births. Results: The overall prevalence was 2.43 cases per 10 000 births (95% CI 2.30 to 2.57). There were regional differences in prevalence ranging from 1.27 to 4.55. Prenatal detection rates varied by registry from >50% of cases to <10% of cases. A total of 546 cases (44.7%) had an isolated oesophageal anomaly, 386 (31.6%) were multiple malformed and 290 (23.7%) had an association or a syndrome. There were 1084 live born cases (88.7%), 43 cases were fetal deaths and 95 cases were terminations of pregnancy. One-week survival for live births was 86.9% and 99.2% if the gestational age was ≥38 weeks and isolated oesophageal atresia was present. Males accounted for 57.3% of all cases and 38.5% of live born cases were born with gestational age <37 weeks. Conclusion: There were regional differences in prevalence of oesophageal atresia in Europe. Half of all cases had associated anomalies. Prenatal detection rate increased from 26% to 36.5% over the two decades. Survival in infants with isolated oesophageal atresia born at term is high.

Recently, two research groups reported that mutations in RMND1 were associated with encephalopathy, elevated lactate, hypotonia, and in some patients seizures or myoclonia in individuals from two consanguineous families. A combined respiratory chain deficiency and a defect in mitochondrial protein translation was found. In this study, we report two siblings who are compound heterozygous for the mutations, c.713A>G and c.1003delG, in RMND1. Respiratory chain enzymatic analysis and BN-PAGE showed a combined OXPHOS deficiency. Western blot analysis indicated normal levels of RMND1, but the assembly of the RMND1 homopolymeric complex was highly impaired. The two siblings had a markedly milder phenotype and longer survival compared to previously reported patients. In addition, they had renal failure and hearing impairment. These two newly described patients contribute to delineation of the clinical spectrum associated with RMND1 aberrations.

Perfluorinated alkylated substances (PFAS) have been extensively used in consumer products and humans are widely exposed to these persistent compounds. A recent study found no association between exposure to perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) and miscarriage, but no studies have examined adverse effect of the more recently introduced PFASs. We therefore conducted a case-control study within a population-based, prospective cohort during 2010-2012. Newly pregnant women residing in the Municipality of Odense, Denmark were invited to enroll in the Odense Child Cohort at their first antenatal visit before pregnancy week 12. Among a total of 2,874 participating women, 88 suffered a miscarriage and 59 had stored serum samples, of which 56 occurred before gestational week 12. They were compared to a random sample (N=336) of delivering women, who had also donated serum samples before week 12. Using a case-control design, 51 of the women suffering a miscarriage were matched on parity and gestational day of serum sampling with 204 delivering women. In a multiple logistic regression with adjustment for age, BMI, parity and gestational age at serum sampling, women with the highest tertile of exposure to perfluorononanoic acid (PFNA) and perfluorodecanoic acid (PFDA) in pregnancy had odds ratios for miscarriage of 16.5 (95% CI 7.4-36.6-36.5) and 2.67 (1.31-5.44), respectively, as compared to the lowest tertile. In the matched data set, the OR were 37.9 (9.9-145.2) and 3.71 (1.60-8.60), respectively. The association with perfluorohexane sulfonic acid (PFHxS) was in the same direction, but not statistically significant, while no association was found with PFOA and PFOS. Our findings require confirmation due to the possible public health importance, given that all pregnant women are exposed to these widely used compounds. © 2015 Jensen et al.

Context In pregnancy, vitamin D insufficiency and deficiency, defined as serum 25-hydroxyvitamin D (25(OH)D) <50 nM, and <25 nM, respectively, may have adverse effects for both mother and child. Prevalence estimates, and identification of subgroups at special risk, may be useful for the planning of preventive strategies. Objective To study the prevalence and risk factors of hypovitaminosis D in early pregnancy. Design and Methods In a cross-sectional study of 1348 women in early pregnancy from the Odense Child Cohort, Denmark, 25(OH)D was determined and correlated to demographic and lifestyle variables (age, nationality, skin tone, parity, prepregnancy body mass index (BMI), smoking and sun exposure), using multiple linear and logistic regression analyses for all year, or stratified for summer and winter. The risk of vitamin D insufficiency was expressed as odds ratios (OR) with 95% confidence intervals in brackets. Results The prevalence of vitamin D insufficiency and deficiency was estimated to 27·8% and 3·5% respectively. In adjusted analyses, vitamin D insufficiency was directly associated with winter season, OR = 1·89 (1·35-2·63); increasing prepregnancy BMI, OR = 1·06 (1·03-1·10); and smoking, OR = 2·7 (1·34-5·41); but was less frequent in nulliparous, OR = 0·47 (0·33-0·68) and tanned Caucasians, OR = 0·63 (0·41-0·97). Season-specific associations having parental origin from outside Europe in summer, OR = 4·13 (1·41-12·13); in winter smoking, OR = 3·15 (1·19-8·36); and prepregnancy BMI, OR = 1·12 (1·06-1·18). Conclusions Vitamin D insufficiency was widespread in early pregnancy. Associations to smoking, prepregnancy BMI and origin outside Europe varied with season. Multiparity and not being tanned in Caucasians represent new risk factors of vitamin D insufficiency. © 2013 John Wiley & Sons Ltd.
