- Background: Most girls with Turner syndrome (TS) require pubertal induction with estrogen, followed by long term replacement. However, no adequately powered prospective studies comparing transdermal with oral 17 beta-estradiol administration exist. This reflects the difficulty of securing funding to study a rare condition with relatively low morbidity/mortality when competing against conditions such as cancer and vascular disease. Protocol Consensus: The TS Working Group of the European Society for Paediatric Endocrinology (ESPE) has agreed to both a 3-year oral and a 3-year transdermal regimen for pubertal induction. Prerequisites include suitable 17 beta-estradiol tablets and matrix patches to allow the delivery of incremental doses based on body weight. Study Proposal: An international prospective cohort study with single centre analysis is proposed in which clinicians and families are invited to choose either of the agreed regimens, usually starting at 11 years. We hypothesise that pubertal induction with transdermal estradiol will result in better outcomes for some key parameters. The primary outcome measure chosen is height gain during the induction period. Analysis: Assessment of the demographics and drop-out rates of patients choosing either oral or transdermal preparations; and appropriate analysis of outcomes including pubertal height gain, final height, liver enzyme and lipid profile, adherence/acceptability, cardiovascular health, including systolic and diastolic blood pressure and aortic root diameter and bone health. Conclusion: The proposed model of prospective data collection according to internationally agreed protocols aims to break the current impasse in obtaining evidence-based management for TS and could be applied to other rare paediatric endocrine conditions.

- There was a highly significant correlation between serum levels of leptin and those of GHBP, except in children with GHD. The possibility that leptin could mediate the effects of body fat mass on GH sensitivity, therefore, merits further investigation.

- To evaluate gender differences in score on 28-joint Disease Activity Score (DAS28), Health Assessment Questionnaire (HAQ) and Signals Of Functional Impairment (SOFI) and to relate these scores to radiographic joint destruction.Methods:In all, 549 patients with early RA (62% women) from the BARFOT (for “Better Anti-Rheumatic FarmacOTherapy”) study were included. At baseline, 1, 2 and 5 years DAS28, HAQ and SOFI scoring, and radiographs of hands and feet were performed. The radiographs were scored using the van der Heijde–Sharp score.Results:In women the DAS28 was significantly higher than in men due to higher scores for general health and tender joints. Likewise, HAQ and VAS pain were rated significantly higher in women. The SOFI score was worse in men during the first 2 years, depending on higher upper limb scores. Total Sharp score (TotSharp), erosion score and joint space narrowing score did not differ between the sexes at any time point. The DAS28 area under the curve (AUC) correlated significantly with TotSharp at 5 years in both genders (r = 0.316, r = 0.313) mainly owing to swollen joints and erythrocyte sedimentation rate (ESR). The SOFI AUC correlated significantly with TotSharp in women (r = 0.135 to 0.220) but not in men.Conclusions:Despite a similar degree of radiographic joint destruction women had, compared with men, worse scores for DAS28 and HAQ, possibly due to higher pain perception and less muscular strength and perhaps because men overestimate their functional capacity.

- The growth response to GH treatment varies between children. Besides regulating longitudinal growth, GH exerts important metabolic effects, including lipolysis. In this study we examined whether GH-induced changes in serum levels of the adipose tissue-derived hormone leptin can be used as a marker for the long term growth response to GH treatment in short prepubertal children. The study group consisted of 150 children (21 girls and 129 boys), who were 3-15 yr of age at the start of GH treatment and had a maximum GH secretory capacity ranging from very low to high. They were treated with GH (0.1 IU/kg x day) and followed for at least 1 yr. The first year mean increase in height SD score was 0.79 (SD, 0.34), with a broad range (0.08-2.27). Serum leptin concentrations were significantly reduced after 1, 3, and 12 months of GH treatment compared with levels at the start of treatment. The growth response correlated with the serum leptin concentration at the start of treatment (r = 0.49; P < 0.0001) and with the change in serum leptin concentration after both 1 month (r = -0.41; P < 0.01) and 3 months (r = -0.60; P < 0.0001) of treatment. When multiple stepwise regression analysis was applied to the auxological and biochemical variables that correlated (P < 0.10) with the first year growth response to GH treatment, the 3-month change in serum leptin concentration was the single most important variable for explaining the variance in individual growth responses. We conclude that leptin levels at the start of GH treatment as well as short term changes in leptin levels in response to GH treatment are valuable markers of the long term growth response.
