    Bird's-eye view of GnRH analog use in a pediatric endocrinology referral center
    (American Association of Clinical Endocrinologists, 2015-06) Watson, Sara E.; Greene, Ariana; Lewis, Katherine; Eugster, Erica A.; Department of Pediatrics, IU School of Medicine
    OBJECTIVE: Gonadotropin-releasing hormone analogs (GnRHa) are standard of care for the treatment of central precocious puberty (CPP). GnRHa have also been prescribed in other clinical settings with the hope of increasing adult stature, although evidence to support this practice is lacking. The degree to which GnRHa are being prescribed for indications other than CPP in routine clinical care has not been described. We sought to systematically examine GnRHa prescribing practices among the pediatric endocrinologists at our academic medical center. METHODS: We reviewed medical records of children treated with GnRHa during a 6-year interval. Variables analyzed included gender, age at start of treatment, indication for therapy, and use of growth hormone as adjunctive treatment. Nonparametric analyses were utilized to compare treatment characteristics of those with CPP versus those without. RESULTS: A total of 260 patients (82% female) aged 8.06 ± 2.68 years were identified. Of these, 191 (73.5%) were treated for CPP, whereas 69 (26.5%) were treated for normally timed puberty in the context of idiopathic short stature/poor predicted height (n = 37), growth hormone deficiency (n = 17), congenital adrenal hyperplasia (n = 10), primary hypothyroidism (n = 4), and developmental delay (n = 1). Of the 161 girls with CPP, GnRHa therapy was initiated at ≥8 years of age in 62 (39%). CONCLUSION: Whereas most patients were treated for CPP, ~27% were treated for other indications. Of girls with CPP, 39% were treated at an age when benefit in terms of height is unlikely. This highlights the need for rigorous studies of GnRHa use for indications beyond CPP.

    Characteristics of Obstructive Sleep Apnea Across the Spectrum of Glucose Tolerance in Obese Adolescents.
    (Frontiers Media, 2018-06-01) Hannon, Tamara S.; Watson, Sara E.; Jalou, Hasnaa E.; Chakravorty, Sangeeta; Mather, Kieren J.; Arslanian, Silva A.; Pediatrics, School of Medicine
    Background: It is not known if dysglycemia and sleep-disordered breathing are linked in adolescents, as in adults. Objective: To perform a pilot study evaluating measures of sleep-disordered breathing across the spectrum of glucose tolerance in obese adolescents. We hypothesized that dysglycemia would be associated with sleep-disordered breathing. Participants/methods: This was a prospective, cross-sectional clinical pilot study that included 57 adolescents [body mass index (BMI) 38.9 ± 8.4 kg/m2] aged 12-18 years (14.5 ± 1.6) with normal glucose tolerance (NGT), or dysglycemia [impaired glucose tolerance (IGT) or type 2 diabetes (T2D)]. Measures: Anthropometrics, overnight polysomnogram, and oral glucose tolerance tests were performed. Participant characteristics and outcome measures were compared by glucose tolerance status. Correlational analyses were conducted to assess the associations between variables of interest. Results: Participants with dysglycemia (n = 21) were not different from those with NGT (n = 36) for BMI, waist circumference, body fat, or sleep characteristics. Nocturnal oxygen desaturation was associated with higher BMI (r = -0.334, p = 0.012). The apnea-hypopnea index (AHI) was not associated with physical and metabolic parameters. Although participants with dysglycemia tended to have higher AHIs (median 3.2, 2.2, and 1.6 events/h for T2D, IGT, and NGT, respectively), there was not a linear relationship between measures of glycemia and AHI. Conclusion: Further study with a larger proportion of youth with prediabetes and T2D is necessary to determine whether evaluation for sleep-disordered breathing is uniformly warranted.

    Morning Blood Pressure is Associated with Sleep Quality in Obese Adolescents
    (Elsevier, 2014-02) Hannon, Tamara S.; Tu, Wanzhu; Watson, Sara E.; Jalou, Hasnaa; Chakravorty, Sangeeta; Arslanian, Silva; Department of Pediatrics, IU School of Medicine
    Objective To examine relationships between blood pressure (BP), adiposity, and sleep quality using overnight polysomnography (PSG) in obese adolescents. Study design Overnight PSG and morning BP measurements were performed in obese (BMI >97th %ile) non-diabetic adolescents (eligible age range 12-18 years, n=49). Subjects were stratified into two groups, one with normal BP, and one with elevated BP, and demographic and clinical characteristics compared between the groups. Multiple linear regression analysis was used to assess the BP effects of sleep quality measures. Results Participants (n=27) had normal morning BP, and 22 (44.9%) had elevated morning BP. There were no differences in age (p=0.53), sex (p=0.44), race (p=0.58) or BMI (p=0.56) between the two BP groups. The group with elevated BP spent shorter percentages of time in rapid eye movement (REM; p=0.006) and slow-wave sleep (SWS; p=0.024). Multiple linear regression analysis showed a lower percent of both REM and SWS were associated with increased morning BP, after adjusting for pubertal stage, sex, race, and BMI. Conclusion Lack of deeper stages of sleep, REM sleep and SWS, is associated with higher morning BP in obese adolescents, independent of BMI. Poor sleep quality should be considered in the work-up of obese youth with hypertension. Intervention studies are needed to evaluate whether improving the quality of sleep will reduce blood pressure elevation.

    Importance: SARS-CoV-2 infection can result in ongoing, relapsing, or new symptoms or other health effects after the acute phase of infection; termed post-acute sequelae of SARS-CoV-2 infection (PASC), or long COVID. The characteristics, prevalence, trajectory and mechanisms of PASC are ill-defined. The objectives of the Researching COVID to Enhance Recovery (RECOVER) Multi-site Observational Study of PASC in Adults (RECOVER-Adult) are to: (1) characterize PASC prevalence; (2) characterize the symptoms, organ dysfunction, natural history, and distinct phenotypes of PASC; (3) identify demographic, social and clinical risk factors for PASC onset and recovery; and (4) define the biological mechanisms underlying PASC pathogenesis. Methods: RECOVER-Adult is a combined prospective/retrospective cohort currently planned to enroll 14,880 adults aged ≥18 years. Eligible participants either must meet WHO criteria for suspected, probable, or confirmed infection; or must have evidence of no prior infection. Recruitment occurs at 86 sites in 33 U.S. states, Washington, DC and Puerto Rico, via facility- and community-based outreach. Participants complete quarterly questionnaires about symptoms, social determinants, vaccination status, and interim SARS-CoV-2 infections. In addition, participants contribute biospecimens and undergo physical and laboratory examinations at approximately 0, 90 and 180 days from infection or negative test date, and yearly thereafter. Some participants undergo additional testing based on specific criteria or random sampling. Patient representatives provide input on all study processes. The primary study outcome is onset of PASC, measured by signs and symptoms. A paradigm for identifying PASC cases will be defined and updated using supervised and unsupervised learning approaches with cross-validation. Logistic regression and proportional hazards regression will be conducted to investigate associations between risk factors, onset, and resolution of PASC symptoms. Discussion: RECOVER-Adult is the first national, prospective, longitudinal cohort of PASC among US adults. Results of this study are intended to inform public health, spur clinical trials, and expand treatment options.
