Objective Hypopituitarism diagnosed in childhood, adolescence and young adulthood has the potential to affect growth and somatic development. Less is known about the impact of such a diagnosis on other aspects of development. Design An analysis of the KIMS Database (Pfizer International Metabolic Database) was performed to explore social, educational and vocational outcomes of adult patients diagnosed in childhood, adolescence and young adulthood compared with adult-onset controls. Patients 2952 adult patients diagnosed with hypothalamic pituitary conditions before the age of 25 were divided into 2 group: childhood-onset [

Objective Published data on eye disorders in patients with Turner syndrome (TS) are limited. We aimed to evaluate the prevalence of eye disorders in patients with TS and assess the association with patient karyotype. Design Cross-sectional, observational study. Patients Eighty-two patients with TS. Measurements We evaluated visual acuity (distance and proximity), intraocular pressure, optic system refraction, orthoposition, frontal eye segment, the eye fundus and colour vision. For eye fundus abnormalities, we conducted ultrasound examinations, visual field evaluations and fluorescein angiography. We statistically tested the association between the prevalence of eye disorders and karyotype. Results 50 (61%) patients had monosomy X; 9 (11%) had mosaicism with a normal 46,XX line; 21 (26%) had structural aberrations; and 2 patients (2%) had other chromosomal abnormalities. Eye disorders were diagnosed in 43 (52%) patients, with 29 (35%) patients having multiple eye defects. Defects related to impaired vision were the most common (44%), followed by strabismus (21%), changes in the posterior eye segment (6%), red-green colour deficiency (5%), changes in the anterior eye segment (5%) and nystagmus (4%). Amblyopia was diagnosed in 13 patients (16%). The most common combinations of ophthalmological defects were hypermetropia and astigmatism with or without other eye problems (12 patients). We found no association between the presence of eye defects and karyotype. Conclusions Detection of eye abnormalities is necessary in all patients directly after being diagnosed with TS to prevent irreversible deterioration of eye function and permanent poor vision. All girls with TS, irrespective of their karyotype, should be referred to an ophthalmologist.

SummaryObjective Growth hormone (GH) replacement may increase bone mineral density (BMD) in GH-deficient (GHD) adults. The goal of this study was to identify predictors of BMD response to GH replacement in GH naive adults. Design and measurements This was a retrospective analysis of data extracted from KIMS (Pfizer International Metabolic Database), an international pharmacoepidemiological survey of adult GHD patients from 31 countries. Patients A total of 231 GH naive adults were identified (115 women and 116 men) who had BMD measured on the same densitometer in the lumbar spine (LS) and/or femoral neck (FN) both at baseline and after 4 years of GH replacement. Results After 4 years, there was a median (10th, 90th percentile) 4·6% (−5·2%, 12·2%) increase in LS BMD over baseline (P = 0·0001). There was a positive correlation between per cent change in LS BMD and age at the onset of pituitary disease (r = 0·25, P = 0·001). There was no change in FN BMD over baseline [0·0% (−7·3%, 8·5%)]. On multivariate analysis, older age at the onset of pituitary disease predicted a greater increase in LS BMD on GH replacement (r = 0·55, P

The last decade has seen a proliferation in options for testosterone replacement. However, little is known as to the benefits of different treatment modalities. Our objective was to determine the testosterone prescription pattern and to examine the impact on various outcome measures.A total of 816 adult-onset hypopituitary males on stable pituitary replacement for at least 1 year were identified from the KIMS database. Patients were classified as either eugonadal (n = 106), or hypogonadal (n = 710) on intramuscular (IM, n = 558), oral (n = 74), transdermal (n = 61), and depot (n = 17) testosterone.After 1 year of stable pituitary replacement therapy, body composition, cardiovascular parameters, GH replacement and quality of life were not significantly different in androgen-replaced hypogonadal patients compared to eugonadal patients. There were no differences in outcome variables within the hypogonadal group according to the testosterone replacement regimen used and no difference in response to GH therapy.The majority of hypopituitary patients in the last decade have received IM testosterone. Body composition, cardiovascular parameters, GH replacement and quality of life were not different between eugonadal and hypogonadal patients and were not differentially affected by the mode of testosterone replacement. These findings are reassuring that there is no major difference in response to different testosterone replacement regimens.

Objectives To examine quality of life (QoL) measured by a utility-weighted index in GH-deficient adults on GH replacement and analyse the impact of demographic and clinical characteristics on changes in utilities during treatment. Design Utilities for items in the QoL-Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDAutility) were estimated based on data obtained from the general population in England and Wales (E&W). These estimates were used to calculate QoL changes in GH-treated patients and compare these with normative population values. Patients A total of 894 KIMS patients (53% women) from E&W were followed for 1 to 6 years. Measurements QoL-AGHDAutility at baseline and at the last reported visit, total QoL-AGHDAutility gain and QoL-AGHDAutility gain per year of follow-up. Results QoL-AGHDAutility in patients before GH treatment differed from the expected population values [0·67 (SD 0·174) vs. 0·85 (SD 0·038), P < 0·0001], constituting a mean deficit of –0·19 (SD 0·168). There was a difference in the mean QoL-AGHDAutility deficit for men [–0·16 (SD 0·170)] and women [–0·21 (SD 0·162)] (P < 0·001). The main improvement occurred during the first year of treatment [reduction of a deficit to –0·07 (SD 0·163) (P < 0·001) in the total cohort]; however, patients’ utilities remained lower than those recorded for the general population during subsequent follow-up (P < 0·001). Despite an observed impact of age, primary aetiology, disease onset and comorbidities on QoL-AGHDAutility, all patients showed a similar beneficial response to treatment. Conclusions QoL-AGHDAutility efficiently monitors treatment effects in patients with GHD. The study confirmed the QoL-AGHDAutility deficit before treatment and a similar QoL-AGHDAutility gain observed after commencement of GH replacement in all patients.

Objective Growth hormone (GH) increases lean body mass and reduces fat mass. However, the long-term changes in weight status during growth hormone treatment, according to age and weight status at onset of treatment, have not previously been reported in large data sets. Methods Changes in BMI-SDS between starting GH treatment and attaining near adult height (NAH) were analysed in 2643 children with idiopathic GH deficiency (IGHD), 281 children small for gestational age (SGA), 1661 girls with Turner syndrome (TS), and 142 children with Prader-Willi syndrome (PWS) in the KIGS database. Results BMI-SDS increased significantly between onset of GH treatment and NAH (IGHD:+0·29, SGA:+0·69, TS:+0·48) except in PWS (-0·02). These increases were greater in children with younger age at onset of GH treatment (significant in all indications) and with lower doses of GH treatment (significant in IGHD & TS) in multiple linear regression analyses also including gender, duration of GH treatment, BMI-SDS and height-SDS at onset of treatment, and birth weight-SDS. Obese children at onset of GH treatment decreased their BMI-SDS, while underweight and normal weight children at onset of GH treatment increased their BMI-SDS independently of GH treatment indication. Conclusions Long-term GH treatment was associated with changes in weight status, which were beneficial for underweight and obese children independent of the indication for GH. However, the increase in BMI-SDS in normal weight children treated with GH needs to be investigated in future prospective longitudinal studies to analyse whether this represents an increase of fat mass, lean body mass or both.
