Predictors of Cardiovascular Morbidities in Adults With 21-Hydroxylase Deficiency Congenital Adrenal Hyperplasia

Context The prevalence of cardiovascular and metabolic complications among adults with 21-hydroxylase deficiency (21OHD) is unknown.Objective We sought to determine the prevalence of cardiovascular and metabolic morbidities among adults with 21OHD and to identify clinical factors and biomarkers associated with cardiovascular outcomes.Methods A 10-year retrospective cross-sectional analysis was conducted on adult patients with confirmed 21OHD, aged 18 to 70 years, who had at least one clinical visit for assessment at the University of Michigan. The presence of cardiovascular diseases (CVDs) and other metabolic comorbidities was extracted from medical records based on International Classification of Diseases (ICD) codes. Medical treatments, glucocorticoid (GC) and mineralocorticoid doses, as well as specific biomarkers of disease control since age 18, were collected for analysis.Results A total of 254 patients with 21OHD, median age of 35 years (interquartile range, 28.25-46 y), were included in the analysis. The prevalence of CVDs in the entire cohort was 7.5%. An increase in prevalence was seen from early adulthood, reaching 25% in patients older than 60 years. Increasing age (adjusted odds ratio [OR], 1.05; 95% CI, 1.01-1.09), hypertension (OR, 4.27; 95% CI, 1.41-12.92), and higher GC doses (OR, 1.51; 95% CI, 1.11-2.06) were significantly associated with prevalent CVDs. Higher plasma renin activity was significantly associated with CVDs (OR, 1.07; 95% CI, 1.01-1.15) but not other biochemical markers of disease.Conclusion Cardiometabolic morbidities are prevalent among adults with 21OHD. Hypertension, age, and GC exposure are the main predictive factors of established CVDs in our cohort.

Automated summary

Cardiometabolic morbidities are prevalent among adults with 21OHD. Hypertension, age, and GC exposure are the main predictive factors of established CVDs in our cohort.
