Glucocorticoids have been reported to exert a marked effect on lipoprotein metabolism. Several studies have shown a potential risk of hyperlipidemia in patients under long-term glucocorticoid therapy. Current management of patients with congenital adrenal hyperplasia (CAH) includes the use of glucocorticoids to attenuate the increased production of undesirable adrenal hormones. A case-control study was designed to compare the serum lipid profiles of 14 patients with CAH under glucocorticoid therapy and 14 normal controls and to determine the characteristics of the profiles. A total of 9 patients (64.3%) had serum total cholesterol (TC) greater than 4.4 mmol/L (170 mg/dL), compared with 6 individuals in the control group (42.3%). Nine patients with CAH (64.3%) had serum triglycerides (TGs) more than 1.0 mmol/L (90 mg/dL), compared with only 2 in the control group (14.3%). Similarly, the mean serum TG was higher in the CAH group versus the controls, 1.33 mmol/L (118 mg/dL) versus 0.75 mmol/L (67 mg/dL), respectively. Serum low-density lipoprotein, (LDL-C) and high-density, lipoprotein (HDL-C) cholesterol were determined in 13 children with CAH and in the 14 controls. Nine CAH patients (69.2%) and 8 controls (57%) had LDL-C greater than 2.8 mmol/L (<110 mg/dL). For HDL-C, 2 children with CAH (15.4%) and 4 controls (28.6%) had levels less than 0.9 mmol/L (35 mg/dL). There were no significant differences for the cholesterol index, 0.24 for the controls and 0.22 for the CAH group. In the CAH group, the mean serum TG level and the percentage of individuals with TGs greater than 1.0 mmol/L were statistically significant compared with the controls. The mean serum TC and LDL-C, as well as the percentage of subjects with levels over the cutoff point, although slightly higher in the CAH group, were of no statistical significance. The results of this pilot study suggest that long-term glucocorticoid therapy in patients with CAH may induce abnormalities in the serum lipid profile characterized mainly by an increment in serum TGs.

PCOS is a metabolic syndrome that exists throughout the world with much clinical heterogeneity. PCOS is now appreciated as encompassing two interrelated metabolic phenomena--insulin resistance and hyperandrogenism. Patients present with oligo-amenorrhea and clinical hyperandrogenism, and the diagnosis is based on clinical grounds with few laboratory tests necessary. Because patients are at higher than normal risk for diabetes, glucose intolerance, and hyperlipidemia, and perhaps at higher risk for coronary heart disease, newly diagnosed patients with PCOS should be evaluated for glucose intolerance and hyperlipidemia. The cornerstone of therapy today includes weight management, and further therapeutic intervention is focused on reproductive and cardiovascular health and treatment of insulin resistance. Clinical case continued The 17-year-old mentioned in the beginning of this article probably does have PCOS. She fits the clinical criteria: oligo-ovulation and hyper-androgenism (the acne and hirsutism). In addition, she is obese, which is also associated with PCOS. Her TSH and prolactin were normal, and as her presentation was not suggestive of an adrenal tumor or congenital adrenal hyperplasia (she had mild hirsutism, and those diagnoses are associated with more severe hyperandrogenism), no further laboratory evaluation was deemed necessary. Once the diagnosis was made, she was screened for lipid abnormalities and for glucose intolerance. Her LDL was 150, HDL 35; oral glucose tolerance test (OGTT) was normal. A pregnancy test was negative, and she was started on OCPs. Devoting herself to exercise and dietary change, she lost 10 pounds in her first 3 months after diagnosis. Her hirsutism and acne have improved with the OCPs and weight loss, and her menses are regular. She has elected to defer oral insulin sensitizers until her weight loss has stabilized. Findings PCOS is common in reproductive-aged women. Diagnosis is clinical and is supported by lab findings; there is significant clinical heterogeneity. Insulin resistance is likely central to the pathophysiology along with androgen excess. Health implications include infertility, diabetes, endometrial cancer, hyperlipidemia, and possibly coronary heart disease. Treatment is evolving and includes weight loss, OCPs, and insulin sensitizers.

Acne is the most common skin disorder. In the majority of cases, acne is a disease that changes its skin distribution and severity over time; moreover, it can be a physically (scar development) and psychologically damaging condition that lasts for years. According to its clinical characteristics, it can be defined as a chronic disease according to the World Health Organization criteria. Acne is also a cardinal component of many systemic diseases or syndromes, such as congenital adrenal hyperplasia, seborrhea-acne-hirsutism-androgenetic alopecia syndrome, polycystic ovarian syndrome, hyperandrogenism-insulin resistance-acanthosis nigricans syndrome, Apert syndrome, synovitis-acne-pustulosis-hyperostosis-osteitis syndrome, and pyogenic arthritis-pyoderma gangrenosum-acne syndrome. Recent studies on the Ache hunter gatherers of Paraguay detected the lack of acne in association with markedly lower rates of obesity, diabetes mellitus, hyperlipidemia, and cardiovascular diseases, a finding that indicates either a nutritional or a genetic background of this impressive concomitance.
