Objective: The objective of this study was to evaluate patients with classic CAH before and after treatment with glucocorticoids/mineralocorticoid and compare the metabolic profile of the well controlled (WC) and poorly controlled (PC) group.
Subjects and methods: We selected newly diagnosed patients and patients monitored for CAH, classical form, regularly using or not glucocorticoids/mineralocorticoid in the Genetics Service Hupes-UFBA, seen from March/2004 to May/2006. All patients underwent detailed clinical evaluation and laboratory tests (glucose, sodium and potassium; total cholesterol, HDL, LDL, triglycerides and uric acid; leptin, 17-hydroxyprogesterone, total testosterone, C peptide, and insulin). Patients with normal androgens were classified as well controlled (WC), and those with high levels of androgens either using or not glucocorticoids/mineralocorticoids were classified as poorly controlled (PC).
Results: We studied 41 patients with CAH: 11 in the WC group and 30 in PC group. Leptin and LDL cholesterol levels were higher in WC than in the PC group (p < 0.05). Uric acid values were lower in WC compared with the PC group (p < 0.05).
Conclusion: Adequate control of CAH with steroids seems safe, as it is associated with only mild changes in lipid profile and leptin values. No other metabolic abnormality was associated with glucocorticoid use. The reason for lower uric acid levels found in WC CAH patients is unknown and should be further studied.
