The endocrine manifestations of spinal muscular atrophy, a real-life observational study.

The introduction of nusinersen, the first therapeutic modality for Spinal Muscular Atrophy (SMA) patients has raised hopes and led to construction of a multi-professional medical SMA service, including pediatric endocrinology. Our study aimed to provide a comprehensive description of the endocrine manifestations of SMA patients with variable degree of sarcopenia. Real-life clinical and laboratory data of 62 SMA patients (age range 3 months to 31 years, 24 type 1, 21 type 2, 17 type 3) were collected including: weight-status, self-reported information on puberty, current pubertal stage, Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), basal gonadotropin and androgen levels. Precocious pubarche (mean age at onset 3.9 ±â€¯2.8 years) was found in 24% (15/62) of the SMA cohort [45.9%(11/24) type 1 and 19%(4/21) type 2]. A higher HOMA-IR predicted precocious pubarche after adjustment for SMA type and age (OR=1.42; 95% CI, 1.05, 1.93, P = 0.025). Bilateral cryptorchidism was found in 60% of type 1 and 30% of type 2 boys; type 3 young adult males attained full puberty. Most of the young women had normal pubertal development and regular menses, regardless of degree of obesity. Our findings suggest that isolated precocious pubarche is associated with early-onset insulin resistance linked to severity of muscular atrophy.

WOMEN WITH NONCLASSIC CONGENITAL ADRENAL HYPERPLASIA HAVE GENDER, SEXUALITY, AND QUALITY-OF-LIFE FEATURES SIMILAR TO THOSE OF NONAFFECTED WOMEN.

Objective: Females with the severe classic forms of congenital adrenal hyperplasia reportedly have a higher frequency of atypical gender identity, nonheterosexual sexual relationships, and cross-gender role behavior. Comparable data and quality-of-life measures among those with the milder, more prevalent form, nonclassic congenital adrenal hyperplasia, are scarce. We aimed to assess health-related quality of life, gender identity, role, and sexual orientation in women with nonclassic congenital adrenal hyperplasia via a prospective, questionnaire-based, case-control study. Methods: Thirty-eight women with nonclassic congenital adrenal hyperplasia (median age 34 years; range, 18 to 44 years) and 62 age-matched female controls were recruited. Outcome measures included the Multi-Gender Identity, Sexuality, and World Health Organization (WHO) quality-of-life questionnaires. Results: Sociodemographic parameters (marital status, number of children, and educational level) were similar for both groups, as were most measures of the Multi-Gender Identity, Sexuality, and WHO quality-of-life questionnaires. However, "sometimes-feeling-as-a-man and sometimes-feeling-as-a-woman" were more frequently reported in the study group compared to the controls (7/38 [18.4%] vs. 3/62 [4.8%], respectively; P = .02). Furthermore, more nonclassic congenital adrenal hyperplasia women reported first falling in love with a woman (4/37 [10.8%] vs. 0/58 [0%]; P = .02). Conclusion: Our findings suggest possible subtle differences in gender identity and sexual orientation between adult nonclassic congenital adrenal hyperplasia females and controls. Quality of life was not impaired in individuals within the study group. The impact of exposure to mildly elevated androgen levels during childhood and adolescence on the female brain warrants more in-depth assessment in further studies.

HEALTH-RELATED QUALITY OF LIFE IN CHILDREN AND ADOLESCENTS WITH NONCLASSIC CONGENITAL ADRENAL HYPERPLASIA.

Objective: Nonclassic congenital adrenal hyperplasia (NCCAH) is a late-onset milder form of congenital adrenal hyperplasia that differs dramatically from the classic form. Health-related quality of life (HRQOL) in pediatric patients with the sole diagnosis of NCCAH has not been determined; therefore, in this study, we aimed to determine whether HRQOL is compromised in comparison to the general population. Methods: Single-center, cross-sectional, case-control study. Twenty-three hydrocortisone-treated children and adolescents (7 males) diagnosed with NCCAH by cosyntropin stimulation test and CYP21A2 gene mutation analysis were recruited to this study; 6 healthy siblings were also recruited. HRQOL was assessed by the child and parent-proxy PedsQL Inventory and compared between NCCAH subjects and healthy siblings. HRQOL scores of NCCAH subjects were compared with known standards from the U.S. and Israeli general healthy populations. Anthropometric measurements of children and parents were performed and compared between NCCAH subjects and healthy siblings. Pearson correlation coefficients were calculated. Results: HRQOL scores of the participants and parents did not differ between NCCAH subjects and healthy siblings. The HRQOL emotional domain scores of the NCCAH patients and parent were significantly lower than the healthy U.S. pediatric population (P = .046) but not different from established standards of the healthy Israeli population (P = .583). Anthropometric measurements were within the normal range and did not differ between NCCAH subjects and their siblings. Total, school functioning, and psychosocial HRQOL domain scores were positively correlated with body mass index-standard deviation score in NCCAH subjects. Conclusion: HRQOL was not adversely affected by NCCAH among adequately treated children and adolescents. Abbreviations: BMI = body mass index; CAH = congenital adrenal hyperplasia; HRQOL = health-related quality of life; NCCAH = nonclassic congenital adrenal hyperplasia; PedsQL = Pediatric Quality of Life Inventory; SDS = standard deviation score.

Adjusting insulin doses in patients with type 1 diabetes who use insulin pump and continuous glucose monitoring: Variations among countries and physicians.

AIMS: To evaluate physicians' adjustments of insulin pump settings based on continuous glucose monitoring (CGM) for patients with type 1 diabetes and to compare these to automated insulin dose adjustments. METHODS: A total of 26 physicians from 16 centres in Europe, Israel and South America participated in the study. All were asked to adjust insulin dosing based on insulin pump, CGM and glucometer downloads of 15 patients (mean age 16.2 ± 4.3 years, six female, mean glycated haemoglobin 8.3 ± 0.9% [66.8 ± 7.3 mmol/mol]) gathered over a 3-week period. Recommendations were compared for the relative changes in the basal, carbohydrate to insulin ratio (CR) and correction factor (CF) plans among physicians and among centres and also between the physicians and an automated algorithm, the Advisor Pro (DreaMed Diabetes Ltd, Petah Tikva, Israel). Study endpoints were the percentage of comparison points for which there was full agreement on the trend of insulin dose adjustments (same trend), partial agreement (increase/decrease vs no change) and full disagreement (opposite trend). RESULTS: The percentages for full agreement between physicians on the trend of insulin adjustments of the basal, CR and CF plans were 41 ± 9%, 45 ± 11% and 45.5 ± 13%, and for complete disagreement they were 12 ± 7%, 9.5 ± 7% and 10 ± 8%, respectively. Significantly similar results were found between the physicians and the automated algorithm. The algorithm magnitude of insulin dose change was at least equal to or less than that proposed by the physicians. CONCLUSIONS: Physicians provide different insulin dose recommendations based on the same datasets. The automated advice of the Advisor Pro did not differ significantly from the advice given by the physicians in the direction or magnitude of the insulin dosing.
