[Children with inflammatory bowel disease: Assessment of the transition from the pediatric to the adult care unit]. / Évaluation de la transition pédiatrie-gastroentérologie d'adultes des enfants atteints de maladie inflammatoire cryptogénique intestinale.

AIM: Assess the transition of children followed for inflammatory bowel disease (IBD) to the adult gastroenterology care unit and the development of joint medical visits (JMVs). PATIENTS AND METHOD: This study was conducted at the Rennes University Hospital (Brittany, France). All patients with IBD and relayed to an adult gastroenterologist (GE) between 2000 and 2014 were included. The following medical data were collected: age, gender, clinical status, disease activity, type of follow-up (freelance or at hospital), medical history, disease locations, and treatments received. Patients who were relayed in the same hospital attended a JMV with both the pediatric and adult gastroenterologists. Patients and parents were interviewed with a questionnaire sent by mail. They were asked how they had perceived the transition with questionnaires containing specific items about the JMV. The answers of the patients who attended JMVs were compared to those who did not attend. RESULTS: Eighty-two patients were included. The patient response rate was 56 % (parents, 59 %). The average age at transition was 18±0.8years. Fifty patients were relayed in the same hospital with 30 attending a JMV. These patients suffered from more severe disease than other patients. Thirty-nine patients felt ready to transition (87 %). The JMV was deemed beneficial or very beneficial (74 %) for both follow-up and the benefits of the GE's knowledge of the medical file. The parents' responses did not differ from the patients'. CONCLUSION: Development of the JMV enables a successful transition for pediatric patients with IBD. It could be improved by developing specific therapeutic education sessions based on transition training.

[Eosinophilic esophagitis in children: Evaluation of practices through a multicenter study]. / L'œsophagite à éosinophiles chez l'enfant : évaluation des pratiques.

Eosinophilic esophagitis (EE) is a recent pathology defined by abnormal immune response of the esophageal mucosa to exogenous allergens, leading to chronic mucosa infiltration by 15 eosinophils per High-Power-Field (Eos/HPF). The present retrospective study was designed to assess the hospital care for children suffering from EE in several hospitals in western France in order to highlight discrepancies and improve future care. Twenty-eight children ranging from 1.5 months to 17 years old were included in the study. Episodes of food blockage were the most frequently reported symptoms (46 %). A ratio of 29 % of EE patients reported macroscopically normal endoscopy; diagnosis was then established upon histological anomalies found in biopsies. The mean eosinophil count was 72.4 Eos/HPF. Centralized immunohistochemical staining revealed the presence of IgG4-responding plasma cells in 76.5 % of patients, as well as IgG4 intraepithelial degranulation in 14 % of them. The evaluation of the treatment plan showed important inter-center discrepancies with only 43 % of patients receiving endoscopic reevaluation. This study objectively highlights heterogeneities in diagnosis and care provided to children suffering from EE. Therefore, improving the consistency of practices seems to be crucial to optimize the patients' outcome. The role of IgG4 as a new diagnosis marker remains to be clarified.

Longitudinal study of bone mineral density in children after a diagnosis of Crohn's disease.

AIM: The purpose of this study was to measure the bone mineral density (BMD) of children with Crohn's disease (CD) and to prospectively assess its evolution. PATIENTS AND METHODS: A total of 27 children (20 boys, seven girls), aged 12.1±2.5 years, were recruited at the time of CD diagnosis. Dual-energy X-ray absorptiometry (DEXA) was used to measure BMD, expressed as Z scores for chronological age (BMD/CA) and bone age (BMD/BA). One year later, BMD was measured again to identify any correlations with disease activity [group A (active disease) vs group R (remission)]. RESULTS: BMD/CA and BMD/BA were negatively correlated with delay in diagnosis (P<0.0001 and P<0.05, respectively). BMD/CA was less than -2 standard deviation (SD) in nine patients and BMD/BA was less -2 SD in four patients. At the follow-up, the increase in BMD was smaller in group A (n=14), whether expressed as absolute values (-0.002 vs 0.040 g/cm(2) per year; P<0.024) or as percentages (-0.2 vs 6.6%; P<0.041); changes in BMD/CA (-0.5 vs -0.1 SD/year) and BMD/BA (-0.3 vs 0 SD/year) did not differ. CONCLUSION: Diagnostic delay greatly affects BMD in children with CD even prior to corticosteroid therapy. The risk of low BMD increases with persistent CD activity, although the risk is reduced in association with bone maturation delay.

[Value of transient elastography in noninvasive assessment in children's hepatic fibrosis]. / Intérêt de l'élastométrie impulsionnelle dans l'évaluation non invasive du stade de fibrose hépatique chez l'enfant.

AIM: Transient elastography (FibroScan) is a novel, noninvasive, rapid bedside method to assess liver fibrosis by measuring liver stiffness. This study aimed to determine the feasibility and reliability of liver stiffness measurement in children with liver diseases. PATIENTS AND METHODS: Liver stiffness measurements were carried out on 72 children, from 4 to 18 years of age, with potential hepatic fibrosis disease. The clinical, biological, ultrasonographic, and endoscopic parameters were noted to identify children with portal hypertension syndrome. The APRI (ASAT-to-platelet ratio index) test was calculated according to the standard formula. An APRI test score higher than 1.5 indicates significant hepatic fibrosis. METAVIR scoring from 14 liver biopsies was compared to the liver stiffness using the Kappa statistic. RESULTS: Twenty-eight patients had viral hepatitis, 20 cystic fibrosis, 16 chronic liver cholestasis, 5 autoimmune hepatitis, and 3 patients had liver fibrosis with uncertain etiology. FibroScan measurements were available in all children. There was good agreement between FibroScan and pathological studies (weighted kappa=0.814). Only 9 children had portal hypertension syndrome with an average measurement of liver stiffness significantly higher than children without portal hypertension (26.5kPa vs 6.4kPa; p<0.01). The APRI test for 6 out of 9 patients scored higher than 1.5. CONCLUSION: These results indicate that liver stiffness measurement is feasible in children and seems to be related to liver fibrosis. Larger prospective studies are needed to validate this FibroScan method.

Effect of a gluten-free diet on bone mineral density in children with celiac disease.

AIM: The aim of the study was to assess the evolution of bone mineral density (BMD) in children with celiac disease and to evaluate the effect of a gluten-free diet (GFD). METHODS: Altogether, 44 children (31 girls and 13 boys) were followed-up. BMD was measured by dual-energy X-ray absorptiometry of the lumbar spine (Hologic QDR 4500). Results are expressed as absolute values for BMD, and as Z scores for chronological age (BMD/CA) and bone age (BMD/BA). Patients were divided into two groups according to whether they followed a diet without (n=34) or with (n=10) gluten for at least 1 year. All patients were clinically free of symptoms at the end of the follow-up. RESULTS: At inclusion, 26 patients (59%) were delayed in bone age, 17 children (38%) had a BMD/CA< or =1 S.D. and six (13.6%) had a BMD/CA< or =2 S.D., whereas nine children (20%) had a BMD/BA< or =1 S.D. and three (6.8%) had a BMD/BA< or =2 S.D. During the follow-up, the BMD increase was greater in the GFD group, as determined by the BMD/CA/year (+0.05+/-0.3 vs -0.34+/-0.4 S.D.; P<0.01) and BMD/BA/year (-0.02+/-0.4 vs -0.4+/-0.6 S.D.; P<0.05). The gain in BMD/BA was smaller in the GFD group because of their need to catch up in bone maturation. CONCLUSION: Celiac children not following a GFD show delays in both bone maturation and mineralization. This prospective study confirms the importance of maintaining a GFD in children with celiac disease until the end of skeletal mineralization even in asymptomatic patients following a non-restricted diet.

[Breastfeeding and vegan diet]. / Allaitement maternel et végétalisme.

Vegan diet in lactating women can induce vitamin B12 deficiency for their children with risk of an impaired neurological development. A 9.5-month-old girl presented with impaired growth and severe hypotonia. She had a macrocytic anemia secondary to vitamin B12 deficiency. MRI showed cerebral atrophy. She was exclusively breastfed. Her mother was also vitamin B12 deficient, secondary to a vegan diet. She had a macrocytic anemia when discharged from the maternity. Vegan diet is a totally inadequate regimen for pregnant and lactating women, especially for their children. Prevention is based on screening, information and vitamin supplementation.

[Hemorrhagic colitis in exclusively breast-fed infants]. / Colite hémorragique chez les nourrissons en allaitement maternel exclusif.

INTRODUCTION: Authors report clinical, biological and endoscopic data of six children aged less 3 months with bloody stools while they were exclusively breast-fed. RESULTS: Two girls and four boys aged 1 to 2 months presented with isolated but recurrent rectal bleeding. All were explored by fiberoptic rectosigmoidoscopy between 1 and 3,2 months. Macroscopic aspects were congestion (6 cases), petechial and ecchymotic (4 cases), with normal mucosal areas (5 cases). Histopathology showed eosinophilic infiltrates in all 5 children with rectal biopsy. Evolution was satisfactory after cow's milk protein exclusion in maternal diet for five children and after weaning in 1. All children were weaned with protein hydrolysate. Cow's milk protein were later introduced without adverse reactions at 6 to 23 months. CONCLUSION: Food allergy can be considered in proctocolitis including exclusive breast-fed children. Evolution after maternal diet is, as usual, simple.
