Results: A total of 118 randomized patients contributed to the statistical analysis. The mean duration of epistaxis per month was significantly shorter with TA than placebo (0.19 on the log scale; SD = 0.07; P = 0.005), corresponding to a decrease of 17.3% (15.7 min) in the duration of epistaxis per month (CI 95%, 5.5-27.6). The median number of epistaxis episodes per month was 22.1 episodes in the placebo arm vs. 23.3 episodes in the TA arm. No thrombophlebitis was observed. Conclusions: In the ATE-RO study, we demonstrated a significant decrease in the duration of epistaxis in HHT patients taking TA. No safety issues were recorded in our cohort of patients.

SummaryBackground and objectives Immediate-release cysteamine bitartrate (Cystagon; Mylan Pharmaceuticals, Canonsburg, PA) may prevent or delay kidney transplantation and other serious outcomes in patients with cystinosis, but has never been subjected to a prospective clinical trial. Cystagon efficacy requires strict lifelong dosing every 6 hours. Such a dosing schedule and Cystagon-associated side effects are often cited by patients as reasons for nonadherence. Design, setting, participants, & measurementsThis open-label, randomized, controlled, crossover trial was powered to show that a new delayed-release formulation of cysteamine bitartrate, RP103, taken every 12 hours, was noninferior to Cystagon for maintenance of white blood cell (WBC) cystine at levels associated with optimal outcomes in the disease.Results Forty-three patients were randomized. Using a mixed-effects statistical analysis model, the least-squares mean peak value of WBC cystine level was 0.6260.05 nmol 1/2 cystine/mg protein after 12 hours under RP103 and 0.5460.05 nmol 1/2 cystine/mg protein after 6 hours under Cystagon, a difference of 0.0860.04 nmol 1/2 cystine/mg protein (95.8% confidence interval, 0-0.16). The average steady-state total daily dose of RP103 was 82% of the incoming steady-state total daily dose of Cystagon. There were three-fold more gastrointestinal side effects compared with using Cystagon.Conclusions A new delayed-release Q12H formulation of cysteamine bitartrate is not inferior to the Q6H formulation (Cystagon) in maintaining low WBC cystine levels in patients with cystinosis but at a lower total daily dose.

Children and young people are seen as fundamental to the design and delivery of clinical research as active and reflective participants. In Europe, involvement of children and young people in clinical research is promoted extensively in order to engage young people in research as partners and to give them a voice to raise their own issues or opinions and for their involvement in planning and decision making in addition to learning research skills. Children and young people can be trained in clinical research through participation in young person advisory groups (YPAGs). Members of YPAGs assist other children and young people to learn about clinical research and share their experience and point of view with researchers, thereby possibly influencing all phases of research including the development and prioritization of research questions, design and methods, recruitment plans, and strategies for results dissemination. In the long term, the expansion of YPAGs in Europe will serve as a driving force for refining pediatric clinical research. It will help in a better definition of research projects according to the patients' needs. Furthermore, direct engagement of children and young people in research will be favorable to both researchers and young people.

Background: To date, there have been no studies comparing cognitive therapy (CT) with Rogerian supportive therapy (RST) in borderline personality disorder. Method: Sixty-five DSM-IV borderline personality disorder outpatients were recruited at 2 centres: Lyon and Marseille. Thirty-three patients were randomly allocated to CT and 32 to RST. The therapists were the same in both groups. Both treatments shared the same duration (1 year) and amount of therapy. Assessment by independent evaluators utilised the Clinical Global Impression (CGI) Scale, the Hamilton Depression Scale, Beck Depression Inventory, Beck Anxiety Inventory, Hopelessness Scale, Young Schema Questionnaire II, Eysenck Impulsivity Venturesomeness Empathy (IVE) Inventory, a self-harming behaviours checklist and scales measuring quality of life and the therapeutic relationship. The response criterion was a score of 3 or less on the CGI, associated with a Hopelessness Scale score of <8. Results: No patient committed suicide during the trial. Fifty-one patients were evaluated at week 24, 38 at week 52 and 21 at week 104. Cognitive therapy retained the patients in therapy for a longer time. The response criterion found no significant between-group differences at any measurement point in the completers. However, at week 24, CT was better than RST on the Hopelessness Scale, IVE scale and regarding the therapeutic relationship. At week 104, the CGI improvement (patient and evaluator) was significantly better in CT than in RST. High baseline depression and impulsivity predicted dropouts. Conclusions: CT retained the patients in therapy longer, showed earlier positive effects on hopelessness and impulsivity, and demonstrated better long-term outcomes on global measures of improvement.

Objectives To determine the long-term effects of delayed-release cysteamine bitartrate (DR-CYS) based on our previous work that established the short-term noninferiority of DR-CYS every 12 hours compared with immediate-release cysteamine bitartrate every 6 hours. Study design We conducted a prospective, controlled, open label, single-arm study of DR-CYS for 2 years in 40 patients to assess efficacy in depletion of cystine in peripheral white blood cells, to assess the dose required to maintain white blood cell content of cystine <1 nmol ½ cystine/mg protein, to measure quality of life using the Pediatric Quality of Life Inventory, change in estimated glomerular filtration rate, and change in height Z-score. Results Through 24 months of study, the mean white blood cell content of cystine was always <1 nmol ½ cystine/mg protein, and the dose of DR-CYS decreased from 43.5-40.1 mg/kg/d (P = .05), and the significant improvement in social function, school function, and in total function scores on the Pediatric Quality of Life Inventory remained. The estimated glomerular filtration rate was maintained and growth velocity was maintained at 24 months compared with the baseline height Z-score. Conclusions The use of a DR-CYS administered every 12 hours to patients with cystinosis is of great benefit to their quality of life and to important biomarkers of disease control, when studied in a prospective, controlled fashion. We suggest that DR-CYS should be considered for substrate depletion in patients with cystinosis.

Improving the management of neonatal diseases and prevention of chronic diseases in adulthood requires a better comprehension of the complex maturational processes associated with newborns' development. Urine-based metabolomic studies play a promising role in the fields of pediatrics and neonatology, relying on simple and noninvasive collection procedures while integrating a variety of factors such as genotype, nutritional state, lifestyle, and diseases. Here, we investigate the influence of age, weight, height, and gender on the urine metabolome during the first 4 months of life. Untargeted analysis of urine was carried out by H-Nuclear Magnetic Resonance (NMR) spectroscopy for 90 newborns under 4 months of age, and free of metabolic, nephrologic, or urologic diseases. Supervised multivariate statistical analysis of the metabolic profiles revealed metabolites significantly associated with age, weight, and height, respectively. The tremendous growth occurring during the neonatal period is associated with specific modifications of newborns' metabolism. Conversely, gender appears to have no impact on the urine metabolome during early infancy. These results allow a deeper understanding of newborns' metabolic maturation and underline potential confounding factors in newborns' metabolomics studies. We emphasize the need to systematically and precisely report children age, height, and weight that impact urine metabolic profiles of infants.

CTNS is required for proper osteoclastic activity. In vitro low doses of cysteamine have beneficial antiresorptive effects on healthy human-derived OCs and may partly correct the CTNS-induced osteoclastic dysfunction in patients with NC. Moreover, in vitro low doses of cysteamine also stimulate osteoblastic differentiation and mineralization, with an inhibitory effect at higher doses, likely explaining, at least partly, the bone toxicity observed in patients receiving high doses of cysteamine.

We did not detect any epilepsy-related factor associated with the severity of ADHD. Twenty-five percent of patients did not respond to methylphenidate. A better understanding of the pathologic process that underlies ADHD development in childhood epilepsy might be required to improve therapeutic strategies.
