Devastating Salt-wasting Crisis in a Four-month-old Male Child with Congenital Adrenal Hyperplasia, Highlighting the Essence of Neonatal Screening

Classic Congenital Adrenal Hyperplasia in males usually presents late until before puberty, but rarely at birth. In cases of undiagnosed CAH, severe deficiency of cortisol may lead to life threatening situation in an infant with acute salt losing crisis. Screening for CAH at birth can lead to better outcomes.

Long-Term Health Outcomes of Korean Adults With Classic Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency

There is a lack of studies regarding the long-term outcomes of Asian adults with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. We hypothesized that adults with CAH are at higher metabolic risk than their age-, and sex-matched controls. We further investigated the long-term health outcome-related factors in adults with CAH. We compared metabolic risk between adults with CAH (71 men, 93 women) and age-, and sex-matched controls (190 men, 261 women) from the Korean National Health and Nutrition Examination Survey data. The presence of obesity, testicular adrenal rest tumors (TARTs), and menstrual irregularity was assessed. Hormone status and treatment regimens were compared according to the presence of adverse outcomes. The median age was 27.0 y and 28.0 y for men and women, respectively. Adults with CAH had a higher waist circumference (88.0 vs. 82.3 cm in men, and 83.5 vs. 72.3 cm in women), and blood pressure (125.0 vs. 113.0 mmHg in men, and 120.0 vs. 104.0 mmHg in women) than age- and sex-matched controls (P<0.05 for all). The 2.7-fold increased risk for hypertension (men) and 2.0-fold increased risk for obesity (women) was significant in patients with CAH (P<0.05 for both). Obese adults with CAH showed significantly higher adrenal limb thicknesses (men) and 17-hydroxyprogesterone and dehydroepiandrosterone sulfate levels (women) (P<0.05 for both). TARTs occurred in 58.1% of men and did not differ by hormone or treatment regimen. Irregular menstruation was observed in 57.1% of women, with higher dehydroepiandrosterone sulfate levels in those with irregular periods. Adults with CAH had a higher metabolic risk than the general population. Poor disease control may increase their risk of metabolic morbidity and menstrual irregularity.

Characteristics of growth in children with classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency during adrenarche and beyond

Context Patients with classic congenital adrenal hyperplasia (CAH) often fail to achieve their full growth potential. Adrenarche may accelerate bone maturation and thereby result in decreased growth in CAH. Objective To analyze the impact of growth during adrenarche on final height of adequately treated classic CAH patients. Design Retrospective, multi-center study. Setting Four academic pediatric endocrinology centers. Participants Fourty-one patients with classical CAH, born between 1990 and 2012. Main outcome measures We assessed skeletal maturation (bone age), growth velocity and (projected) adult height outcomes, and analyzed potential influencing factors, such as sex, genotype, and glucocorticoid therapy. Results Patients with classic CAH were shorter than peers (-0.4SDS±0.8SD) and their parents (corrected final height -0.6SDS±1.0SD). Analysis of growth during adrenarche revealed two different growth patterns: patients with accelerating bone age (49%), and patients with non-accelerating bone age compared to chronological age (BA-CA). Patients with accelerating BA-CA were taller than the normal population during adrenarche years (p=0.001) and were predicted to achieve a lower adult height SDS (-0.9SDS, 95%CI -1.3;-0.5) than non-accelerating patients when assessed during adrenarche (0.2SDS, 95%CI -0.3;0.8). Final adult height was similarly reduced in both accelerating and non-accelerating BA-CA groups (-0.4SDS, 95%CI -0.9;0.1 vs -0.3SDS, 95%CI -0.8;0.1). Conclusions Patients with and without significant bone age advancement, and thus differing height prediction during adrenarche, showed similar (predicted) final height when reassessed during pubertal years. Bone age alone should not be used during adrenarche as clinical marker for metabolic control in CAH treatment.

Non-Classic Congenital Adrenal Hyperplasia in Two Adolescents With Gender Dysphoria

The care of transgender individuals is multidisciplinary including medical, surgical, psychiatric, and psychological health professionals. We here report 2 cases of nonclassic congenital adrenal hyperplasia (CAH) coincidently discovered during the clinical and biochemical evaluation prior to hormonal treatment for gender dysphoria. Elevated 17-OH-progesterone and androstenedione led to further investigations including adrenocorticotropic hormone stimulation test and genetic evaluation of 21CYPA2 confirming the diagnosis of CAH in both individuals. The findings may have implications for future surgical treatment and in the case of transwomen for the choice of antiandrogenic treatment. These cases therefore confirm the importance of thorough clinical and biochemical evaluation of transgender individuals before initiation of hormone therapy.
