BACKGROUND: Classic 21-hydroxylase deficiency (21HD) presents some traits of the metabolic syndrome. AIM: To characterize discrete alterations of lipid and carbohydrate metabolism in children and young adults with classic 21HD, which could predict early atherogenesis. PATIENTS AND METHODS: Twenty-seven Caucasian patients with classic 21HD (4-31 years); 27 sex-, age- and BMI-matched controls. Clinical parameters, hormonal status and genotype were assessed in all patients. Lipid parameters, including relative (%) and absolute (mg/dl) small-dense low-density lipoproteins subfractions (sd-LDL) were measured in patients and controls. Oral glucose tolerance tests were performed in both groups. RESULTS: sd-LDL (%) was significantly higher in patients than controls (39.7 +/- 5.9 vs. 35.5 +/- 5.7%; p = 0.008). The same applies for absolute sd-LDL (mg/dl) (42.6 +/- 11.9 vs. 36.4 +/- 7.5; p = 0.029). HDL-cholesterol was lower in patients (p = 0.032). Fasting glucose and insulin were significantly higher in patients. Similar differences were noticed for HOMA-IR (p = 0.001), IRI (p = 0.001) and HOMA-B (p = 0.002). IRI correlated directly and significantly with the total hydrocortisone dose and the duration of treatment. Fasting glucose correlated with absolute sd-LDL. No obvious differences were seen between clinical forms or genotype groups. CONCLUSIONS: Substitution therapy should be adapted particularly at young ages to prevent early atherogenesis and cardiovascular risk in later life. Copyright 2010 S. Karger AG, Basel.
