Abstract

CONTEXT: Congenital adrenal hyperplasia (CAH) is lethal in its most severe forms if not treated with glucocorticoids. However, glucocorticoids may increase the risk of cardiovascular and metabolic morbidity. OBJECTIVE: This study aimed to study cardiovascular and metabolic morbidity in CAH. DESIGN, SETTING, AND PARTICIPANTS: Patients with CAH due to 21-hydroxylase deficiency (n = 588; >80% with known CYP21A2 mutations) were compared with controls matched for sex, year, and place of birth (n = 58 800). Data were obtained by linking national population-based registers. Subgroup analyses were performed regarding sex, clinical severity (salt wasting, simple virilizing, nonclassic), CYP21A2 genotype (null, I2 splice, I172N, P30L), and stratified by the introduction of neonatal screening, age groups, and nonobesity. MAIN OUTCOME MEASURES: To study cardiovascular and metabolic morbidity in CAH. RESULTS: In CAH, both any cardiovascular and metabolic disorders (OR [odds ratio], 3.9; 95% CI [confidence interval], 3.1-5.0), and cardiovascular disease (OR, 2.7; 95% CI, 1.9-3.9) were increased. Separate analyses of the individual diseases showed higher frequencies in CAH of hypertension, hyperlipidemia, atrial fibrillation, venous thromboembolism, obesity, diabetes (mainly type 2), obstructive sleep disorder, thyrotoxicosis, and hypothyroidism. Similar results were seen in the stratified groups. On the subgroup level, females were generally more affected (especially I172N and the nonclassic group), as were males with the null genotype. CONCLUSIONS: CAH was associated with excess cardiovascular and metabolic morbidity but the mechanism is not certain as the glucocorticoids were not assessed. Hypothyroidism and obesity may be an effect of close observation. However, more severe conditions were presumably detected equally in patients and controls. Screening for diabetes and other metabolic disorders that increase cardiovascular risk is important.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
