RESUMEN

INTRODUCTION: Inactivating mutations in the enzyme hexose-6-phosphate dehydrogenase (H6PDH), the enzyme responsible for NADPH generation playing critical role in 11-hydroxysteroid dehydrogenase type 1 (11b-HSD1) activity, cause apparent cortisone reductase deficiency (ACRD). It leads to increased metabolic clearance rate of cortisol due to a defect in cortisone to cortisol conversion by 11b-HSD1. We want to analyse the process of the disease, efficacy of long-lasting treatment with glucocorticoids throughout childhood and adolescence in only male patient with ACRD. CASE PRESENTATION: A 23 year-old male patient was diagnosed with ACRD at the age of 7 years. The clinical manifestation of ACRD was presented by precocious pubarche. His bone age was assessed as 11.5 years old. Blood tests indicated increased the plasma androgen, with elevated 17-hydroxyprogesterone concentration. A steroid profile analysis of a 24-h urine collection showed extremely reduced THF + allo-THF/THE ratio - 0.021 (normal range: 0.7-1.2). Two months of hydrocortisone therapy was ineffective and dexamethasone was administered in initial dose of 0.375 mg/24 h. Next dosage beetwen 0.125 mg/24h and 0.375 mg/24h has been changed depending on the patient's results of laboratory tests and condition. Control laboratory studies indicated suppression of excess adrenal androgen synthesis, but we never got the THF + allo-THF/THE ratio in normal values. He did not develop any serious side effects, although dexamethasone is the most potent adrenal suppression drug. CONCLUSIONS: Hydrocortisone treatment is ineffective in ACRD patients because it was rapidly metabolized to cortisone. We have found the balance between the dexamethasone treatment effects of adrenal suppression and the achievement of full height potential considering the condition of our patient.

RESUMEN

Overweight women with polycystic ovary syndrome (PCOS) were randomized to a high protein (HP; 40% carbohydrate and 30% protein; n = 14) or a low protein (LP; 55% carbohydrate and 15% protein) diet (n = 14). The intervention consisted of 12 wk of energy restriction (approximately 6000 kJ/d), followed by 4 wk of weight maintenance. Pregnancies (two HP and one LP); improvements in menstrual cyclicity, lipid profile, and insulin resistance (as measured by the homeostasis model); and decreases in weight (7.5%) and abdominal fat (12.5%) occurred independently of diet composition. Improvements in menstrual cyclicity were associated with greater decreases in insulin resistance and fasting insulin (P = 0.011). On the LP diet, high density lipoprotein cholesterol decreased 10% during energy restriction (P = 0.008), and the free androgen index increased 44% in weight maintenance stages (P = 0.027). Weight loss leads to improvements in cardiovascular and reproductive parameters potentially mediated by improvements in surrogate measures of insulin resistance. An HP weight loss diet may result in minor differential endocrine and metabolic improvements.

RESUMEN

Evidence suggests that hyperinsulinemic insulin resistance may increase serum levels of ovarian androgens and reduce sex hormone-binding globulin (SHBG) levels in humans. The present study was conducted to assess the effect of administration of the biguanide metformin, a drug commonly used in the treatment of diabetes mellitus, on androgen and insulin levels in 24 hirsute patients. The patients selected for the study were obese, with a body mass index higher than 25 kg/m2 and high fasting insulin (> 90 pmol/L) and low SHBG levels (< 30 nmol/L). All patients were given a low calorie diet (1500 Cal/day) and randomized for either metformin administration at a dose of 850 mg or a placebo, twice daily for 4 months, in a double blind study. In the placebo group, diet resulted in a significant decrease in body mass index (30.8 +/- 1.0 vs. 32.7 +/- 1.5 kg/m2; P < 0.0001), fasting insulin (127 +/- 11 vs. 156 +/- 14 pmol/L; P < 0.01), non-SHBG-bound testosterone (0.19 +/- 0.02 vs. 0.28 +/- 0.03 nmol/L; P < 0.02), androstenedione (5.8 +/- 0.5 vs. 9.0 +/- 1.1 nmol/L; P < 0.03), and 3 alpha-diolglucuronide (8.6 +/- 1.1 vs. 11.7 +/- 1.9; P < 0.005) plasma concentrations and a significant increase in the glucose/insulin ratio (0.047 +/- 0.005 vs. 0.035 +/- 0.003; P < 0.001) and plasma concentrations of SHBG (26.0 +/- 3.3 vs. 19.1 +/- 1.9 nmol/L; P < 0.001) and dehydroepiandrosterone sulfate (8.7 +/- 1.5 vs. 8.4 +/- 1.3; P < 0.05). Beneficial effects of diet were not significantly different in the patients who were given metformin instead of placebo. These results confirm that weight loss induced by a low calorie diet is effective in improving hyperinsulinemia and hyperandrogenism in obese and hirsute women. With our study design, metformin administration had no additional benefit over the effect of diet.

RESUMEN

To investigate the relationship between overweight and hyperandrogenism, a 1500 kcal/day diet was prescribed for 4 months to 23 hirsute and obese patients. This diet decreased body mass index from 29.9 +/- 4.9 to 27.2 +/- 4.4 kg/m2 (P < 0.008), but had no significant effect on fasting insulin levels (18.9 +/- 14.2 vs. 21.1 +/- 9.6 mlU/l). Weight lost increased significantly (P < 0.008) the plasma concentration of sex-hormone binding-globulin (SHBG) from 21.2 +/- 10.6 to 26.2 +/- 13.5 nmol/l and decreased significantly (P < 0.04) the SHBG-unbound testosterone concentration from 9.3 +/- 6.2 to 7.2 +/- 4.8 ng/dl, without changing the concentrations of the main androgens measured in this study. Moreover, during diet 5 patients in amenorrhea and 8 among 13 patients with irregular menstrual cycle recovered regular menses. We concluded that the control of excess body weight in hirsute women is effective but not sufficient to improve hyperandrogenism.
