Abstract
UNLABELLED: Few studies assessed carotid artery intima-media thickness (CA-IMT) and left ventricular (LV) function in children with congenital adrenal hyperplasia (CAH) as compared to adults. This study aimed to assess carotid artery structural changes and myocardial function with CAH. The study included 32 children with classic CAH and 32 healthy children matched for age, gender, pubertal status, and socioeconomic status. Blood levels of high-sensitivity C-reactive protein (hs-CRP) and circulating endothelial cells (CECs) were measured. LV mass (LVM) and function were assessed using conventional echocardiography. Duplex ultrasonography was used to measure CA-IMT. Compared to controls, patients had higher hs-CRP and CEC concentrations (p < 0.001) and increased CA-IMT (p < 0.001), indicating vascular endothelial injury and subclinical atherosclerosis; higher LVM index (LVMI) (p < 0.001), indicating LV hypertrophy; and lower ratio of E/A wave and prolonged mitral deceleration time (DcT) and isovolumic relaxation times (IVRTs) (p < 0.001), indicating LV dysfunction. Abnormalities were marked in uncontrolled children on medical treatment. Testosterone levels were positively correlated with CA-IMT, LVMI, and DcT values. CONCLUSION: This study indicates that children with CAH and enhanced androgen levels are at increased risk of vascular endothelial injury, subclinical atherosclerosis, and LV dysfunction. These findings highlight early monitoring of children with CAH for cardiovascular abnormalities.
