- Patients with biallelic loss-of-function variants of AIRE suffer from autoimmune polyendocrine syndrome type-1 (APS-1) and produce a broad range of autoantibodies (auto-Abs), including circulating auto-Abs neutralizing most type I interferons (IFNs). These auto-Abs were recently reported to account for at least 10% of cases of life-threatening COVID-19 pneumonia in the general population. We report 22 APS-1 patients from 21 kindreds in seven countries, aged between 8 and 48 yr and infected with SARS-CoV-2 since February 2020. The 21 patients tested had auto-Abs neutralizing IFN-α subtypes and/or IFN-ω; one had anti–IFN-β and another anti–IFN-ε, but none had anti–IFN-κ. Strikingly, 19 patients (86%) were hospitalized for COVID-19 pneumonia, including 15 (68%) admitted to an intensive care unit, 11 (50%) who required mechanical ventilation, and four (18%) who died. Ambulatory disease in three patients (14%) was possibly accounted for by prior or early specific interventions. Preexisting auto-Abs neutralizing type I IFNs in APS-1 patients confer a very high risk of life-threatening COVID-19 pneumonia at any age.

- <b><i>Introduction:</i></b> Almost 20 years after the first international guidelines on the diagnosis and treatment of GHD have been published, clinical practice varies significantly. The low accuracy of endocrine tests for GHD and the burden caused by ineffective treatment of individual patients were strong motives for national endocrine societies to set up national guidelines regarding how to diagnose GHD in childhood. This audit aims to review the current state and identify common changes, which may improve the diagnostic procedure. <b><i>Methods:</i></b> A group of eight German pediatric endocrinologists contacted eight pediatric endocrinologists from Spain, France, Poland, the UK, the Netherlands, Denmark, Italy, and the US. Each colleague responded as a representative for the own country to a detailed questionnaire containing 22 open questions about national rules, guidelines, and practice with respect to GHD diagnostics and GH prescription. The results were presented and discussed in a workshop and then documented in this study which was reviewed by all participants. <b><i>Results:</i></b> National guidelines are available in 7 of 9 countries. GH is prescribed by pediatric endocrinologists in most countries. Some countries have established boards that review and monitor prescriptions. Preferred GH stimulation tests and chosen cutoffs vary substantially. Overall, a trend to lowering the GH cutoff was identified. Priming is becoming more popular and now recommended in 5 out of 9 countries; however, with different protocols. The definition of pretest-conditions that qualify the patient to undergo GH testing varies substantially in content and strictness. The most frequently used clinical sign is low height velocity, but definition varies. Height, IGF-1, and bone age are additional parameters recommended in some countries. <b><i>Conclusions:</i></b> GHD diagnostics varies substantially in eight European countries and in the US. It seems appropriate to undertake further efforts to harmonize endocrine diagnostics in Europe and the US based on available scientific evidence.

- Context The Kabi/Pfizer International Growth Database (KIGS) is a large, international database (1987-2012) of children treated with recombinant human growth hormone (rhGH) in real-world settings. Objective This work aimed to evaluate the safety and efficacy of rhGH from the full KIGS cohort. Methods Data were collected by investigators from children with growth disorders treated with rhGH (Genotropin [somatropin]; Pfizer). Safety was evaluated in all treated patients, and efficacy in those treated for 1 year or more. A subgroup included patients treated for 5 years or more (>= 2 years prepubertal) who had reached near-adult height (NAH). Main outcomes included adverse events (AEs), serious AEs (SAEs), and height growth. Results The full KIGS cohort (N = 83 803 [58% male]) was treated for idiopathic GH deficiency (IGHD; 46.9%), organic GHD (10.0%), small for gestational age (SGA; 9.5%), Turner syndrome (TS; 9.2%), idiopathic short stature (ISS; 8.2%), and others (16.2%). Median rhGH treatment duration was 2.7 years and observation 3.1 years. SAEs occurred in 3.7% of patients and death in 0.4%. The most common SAEs were recurrence of craniopharyngioma (n = 151), neoplasm (n = 99), and cancer (n = 91); and scoliosis (n = 91). Median first-year delta height-SD score (SDS) (Prader) in prepubertal patients was 0.66 (IGHD), 0.55 (ISS), 0.58 (TS), and 0.71 (SGA). Median gains in NAH-SDS were 1.79 (IGHD), 1.37 (ISS), and 1.34 (SGA) for boys, and 2.07 (IGHD), 1.62 (ISS), 1.07 (TS), and 1.57 (SGA) for girls. Conclusion Data from KIGS, the largest and longest running international database of rhGH-treated children, show that rhGH is safe and increases short-term height gain and adult height across GHD and non-GHD conditions.

Recommendations for Diagnosis and Treatment of Pseudohypoparathyroidism and Related Disorders: An Updated Practical Tool for Physicians and Patients

- Patients affected by pseudohypoparathyroidism (PHP) or related disorders are characterized by physical findings that may include brachydactyly, a short stature, a stocky build, early-onset obesity, ectopic ossifications, and neurodevelopmental deficits, as well as hormonal resistance most prominently to parathyroid hormone (PTH). In addition to these alterations, patients may develop other hormonal resistances, leading to overt or subclinical hypothyroidism, hypogonadism and growth hormone (GH) deficiency, impaired growth without measurable evidence for hormonal abnormalities, type 2 diabetes, and skeletal issues with potentially severe limitation of mobility. PHP and related disorders are primarily clinical diagnoses. Given the variability of the clinical, radiological, and biochemical presentation, establishment of the molecular diagnosis is of critical importance for patients. It facilitates management, including prevention of complications, screening and treatment of endocrine deficits, supportive measures, and appropriate genetic counselling. Based on the first international consensus statement for these disorders, this article provides an updated and ready-to-use tool to help physicians and patients outlining relevant interventions and their timing. A life-long coordinated and multidisciplinary approach is recommended, starting as far as possible in early infancy and continuing throughout adulthood with an appropriate and timely transition from pediatric to adult care.
