Abstract Background: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is the most common cause of primary adrenal insufficiency during childhood and patients are at risk for life-threatening adrenal crisis. In a recent study from our group, we reported gastrointestinal and upper respiratory tract infections as the two most common precipitating events for adrenal crises and hospitalizations across all ages. We also reported 11 incidents of life-threatening hypoglycemic events in children, sometimes accompanied by seizures. Objective: To evaluate the annual rates of illnesses in patients with CAH. Methods: We retrospectively reviewed longitudinally collected data over 23 years from 156 CAH patients enrolled in our CAH natural history study (www.clinicaltrials.gov #NCT00250159). Incidence of illnesses and occurrence of stress-dose days were computed per person-years. Incidence rate ratio (IRR) with 95% confidence intervals (CI) were calculated for comparisons. Results: A total of 2298 visits (1909 for children and 389 for adults) were available for evaluation among the 156 patients (21-OHD: 97.4%). A total of 1870 illness events (1664 in children) were observed in 143 patients (121 children) and 2710 stress-dose days (2460 in children) were observed in 141 patients (120 children) during the study period. The incidence rate of illnesses was higher in children than adults (1.5 vs. 0.5 illnesses/person-years, IRR = 3.1, 95% CI 2.7 - 3.6; P<.0001) with incidence highest in young patients: 2.5 illnesses/person-years in <3 year olds. Similarly, the stress-dose days were higher in children than adults (2.2 vs. 0.6 days/person-years, IRR = 3.8, 95% CI 3.3 - 4.3; P<.0001). Conclusions: Patients with CAH do not appear to have higher rates of infectious illnesses than expected, but remain at risk for life-threatening adrenal crises. As expected, illness rates are higher during childhood than adulthood. Prevention of adrenal crisis is crucial and is best accomplished through repeated age-specific education of patients and caregivers.

21 Hydroxylase Deficiency

Congenital adrenal hyperplasia (CAH) is an inherited disorder caused by the absence or severely impaired activity of steroidogenic enzymes involved in cortisol biosynthesis. More than 90% of cases result from 21-hydroxylase deficiency (21OHD). To prevent life-threatening adrenal crisis and to help perform appropriate sex assignments for affected female patients, newborn screening (NBS) programs for the classical form of CAH have been introduced in numerous countries. In Japan, the NBS for CAH was introduced in 1989, following the screenings for phenylketonuria and congenital hypothyroidism. In this review, we aim to summarize the experience of the past 30 years of the NBS for CAH in Japan, composed of four parts, 1: screening system in Japan, 2: the clinical outcomes for the patients with CAH, 3: various factors that would impact the NBS system, including timeline, false positive, and LC-MS/MS, 4: Database composition and improvement of the screening program.

Adrenal myelolipomas are relatively rare tumours composed of adipocytes and myeloid cells that arise in response to chronic adrenocorticotropic hormone stimulation. We present the case of bilateral adrenal myelolipomas in a 39-year-old man with untreated congenital adrenal hyperplasia (CAH) presenting with acute adrenal insufficiency and severe virilisation. Phenotypically, he is a man of short stature and has hyperpigmentation of the skin, gingiva and nail beds. Genital examination revealed micropenis and no palpable testes. Laboratory testing was consistent with primary adrenal insufficiency. An abdominal CT showed bilateral adrenal myelolipomas. An MRI of the pelvis revealed female reproductive organs. Chromosome study showed a karyotype of 46,XX. A CYP21A2 gene mutation confirmed diagnosis of CAH with 21-hydroxylase deficiency. The patient was treated with stress dose corticosteroids, subsequently tapered to physiological doses. We review previously reported cases and discussed diagnosis and treatment, including hormonal therapy and psychological approach.

21 Hydroxylase Deficiency

Abstract Introduction: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare autosomal recessive disorder that results in little or no cortisol biosynthesis, increased production of precursor steroids, and excess production of adrenal androgens. Glucocorticoid (GC) treatment, the current standard of care for CAH, is used to correct cortisol deficiency and reduce excessive androgens. Elevated 17-hydroxyprogesterone (17OHP) is used for diagnosis and management. GC titration to achieve 17OHP <1000 ng/dL may be targeted for adrenal androgen control; however, patients with 17OHP <1000 ng/dL might be at risk for complications of long-term GC excess. This real-world study evaluated adrenal androgen levels and potential GC complications in adolescents and adults with CAH. Methods: TriNetX, a research network that includes electronic medical records from >37 million U.S. patients, was searched on 30Aug2019 for patients who met the following criteria: diagnosis code of E25.0 (ICD-10) or 255.2 (ICD-9); history of GC use; available 17OHP laboratory result; and ≥15 years of age (“grown”) at the most recent 17OHP assessment. Patients were categorized as “adequately controlled” (17OHP <1000 ng/dL) or “poorly controlled” (17OHP ≥1000 ng/dL). Assessments included: demographics; laboratory results for 17OHP, adrenocorticotropic hormone (ACTH), and androstenedione (A4); and low-density lipoprotein (LDL). Adequately vs. poorly controlled groups were compared using Chi-square tests and t-tests. Results: Of 511 grown CAH patients, 352 were adequately controlled and 159 were poorly controlled. Mean concentrations for 17OHP were 244 and 5939 ng/dL in the adequately and poorly controlled cohorts, respectively (p<0.01). Adequately controlled patients also had lower ACTH and A4 than poorly controlled patients: ACTH (72 vs 389 pg/mL, p<0.01); A4 (82 vs 256 ng/dL, p<0.01). Compared to poorly controlled patients, adequately controlled patients were more likely to be female (81% vs 57%, p<0.01) and older (mean birth year: 1981 vs 1986, p<0.01). Adequately controlled patients also had evidence of more metabolic and infection complications, including higher mean LDL (105 vs 94.3 mg/dL, p=0.02), more type 2 diabetes mellitus (9% vs 4%, p=0.08), and more respiratory tract infections (21% vs 11%, p=0.01). Conclusions: In this retrospective analysis, patients with adequately controlled CAH (17OHP <1000 ng/dL) had better adrenal androgen control (lower A4) but also higher rates of complications potentially related to excessive GC exposure. These findings highlight the current challenges of managing CAH with GC regimens alone.

Abstract Context Patients with congenital adrenal hyperplasia (CAH) are at risk for life-threatening adrenal crises. Management of illness episodes aims to prevent adrenal crises. Objective We evaluated rates of illnesses and associated factors in patients with CAH followed prospectively and receiving repeated glucocorticoid stress dosing education. Methods Longitudinal analysis of 156 patients with CAH followed at the National Institutes of Health Clinical Center over 23 years was performed. The rates of illnesses and stress-dose days, emergency room (ER) visits, hospitalizations, and adrenal crises were analyzed in relation to phenotype, age, sex, treatment, and hormonal evaluations. Results A total of 2298 visits were evaluated. Patients were followed for 9.3 ± 6.0 years. During childhood, there were more illness episodes and stress dosing than adulthood (P < 0.001); however, more ER visits and hospitalizations occurred during adulthood (P ≤ 0.03). The most robust predictors of stress dosing were young age, low hydrocortisone and high fludrocortisone dose during childhood, and female sex during adulthood. Gastrointestinal and upper respiratory tract infections (URIs) were the two most common precipitating events for adrenal crises and hospitalizations across all ages. Adrenal crisis with probable hypoglycemia occurred in 11 pediatric patients (ages 1.1 to 11.3 years). Undetectable epinephrine was associated with ER visits during childhood (P = 0.03) and illness episodes during adulthood (P = 0.03). Conclusions Repeated stress-related glucocorticoid dosing teaching is essential, but revised age-appropriate guidelines for the management of infectious illnesses are needed for patients with adrenal insufficiency that aim to reduce adrenal crises and prevent hypoglycemia, particularly in children.

21 Hydroxylase Deficiency

Context: Reports on mortality in patients with congenital adrenal hyperplasia (CAH) are lacking. Objective: This study sought to study mortality and causes of death in CAH. Design, Setting, and Participants: We studied patients with CAH (21-hydroxylase deficiency, n = 588; CYP21A2 mutations known, >80%), and compared them with controls (n = 58 800). Data were derived through linkage of national population-based registers. Main Outcome Measures: Mortality and causes of death. Results: Mean age of death was 41.2 ± 26.9 years in patients with CAH and 47.7 ± 27.7 years in controls (P < .001). Among patients with CAH, 23 (3.9%) had deceased compared with 942 (1.6%) of controls. The hazard ratio (and 95% confidence interval) of death was 2.3 (1.2–4.3) in CAH males and 3.5 (2.0–6.0) in CAH females. Including only patients born 1952–2009, gave similar total results but only patients with salt wasting (SW) or with unclear phenotype had an increased mortality. The causes of death in patients with CAH were adrenal crisis (42%), cardiovascular (32%), cancer (16%), and suicide (10%). There were seven additional deaths in CAH individuals with incomplete or reused personal identification number that could not be analyzed using linkage of registers. Of the latter, all except one were deceased before the introduction of neonatal screening in 1986, and most of them in the first weeks of life, probably in an adrenal crisis. Conclusions: CAH is a potentially lethal condition and was associated with excess mortality due to adrenal crisis. The SW phenotype also seemed to have worse outcome in children and adults due to adrenal crisis and not only before the introduction of neonatal screening.
