MENSTRUAL AND REPRODUCTIVE FUNCTION IN WOMEN WITH TYPE 1 DIABETES.

OBJECTIVE: Menstrual irregularities, reproductive abnormalities, and androgen excess are reported to be more prevalent in women with type 1 diabetes (T1D). The objective of this study was to investigate the prevalence of menstrual irregularities, reproductive abnormalities, and androgen excess among women with T1D and their age-matched controls. METHODS: A survey requesting information regarding menstrual and reproductive histories was administered to all participants. Results were stratified according to age (18 to 40, 40 to 50, and >50 years). RESULTS: There were no significant differences between women with and without diabetes in age at menarche, cycle length, or androgen excess in any group. Women who self-reported difficulty with glycemic control were more likely to report irregular menses than controls (P = .04). Among women who reported ever being pregnant, there were fewer pregnancies (P = .02) and live births (P = .002) in women with T1D. Women with T1D reported a lower frequency of oral contraceptive use (P = .003), despite being less likely to smoke (P = .016). CONCLUSION: Menstrual and reproductive abnormalities were not observed more frequently in women with T1D in this study. Subtle but measurable differences in menstrual and reproductive function were confined to the subgroup of women who perceived poor control of their diabetes. Additional prospective studies of T1D and menstrual and reproductive function would be useful.

Bilateral adrenal hemorrhage in polycythemia vera.

Bilateral adrenal hemorrhage (BAH) is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency.

Does androgen excess contribute to the cardiovascular risk profile in postmenopausal women with type 2 diabetes?

The purpose of this study was to determine if postmenopausal women with type 2 diabetes have clinical and biochemical evidence of androgen excess as a potential contributor to an increase in risk for coronary heart disease when compared with women without diabetes. Fasting glucose, insulin, lipids, sex hormone-binding globulin (SHBG), and sex steroids (from pooled samples) (total testosterone and free testosterone [non-SHBG-T], androstenedione [A-dione], total estrogens) were measured at baseline in 16 postmenopausal women with type 2 diabetes treated with diet or a sulfonylurea and 17 age-matched controls. Measurements of glucose, insulin, and sex steroids were repeated at hourly intervals for 3 hours after oral glucose administration. Hirsutism scores and insulin sensitivity (homeotasis model assessment [HOMA] insulin [SI]) were obtained. Women with type 2 diabetes were more hyperglycemic, hyperinsulinemic, and insulin-resistant (HOMA SI, 46.7 +/- 7.0 vs 12.9 +/- 2.0, P < .001), and had higher total to high-density lipoprotein cholesterol (TC/HDL) ratios, lower SHBG (20.8 +/- 3.5 vs 59.3 +/- 14.4 nmol/L, P < .05), higher non-SHBG-T (0.225 +/- 0.025 vs 0.135 +/- 0.021 nmol/L, P < .05), and higher hirsutism scores (1.1 +/- 0.3 vs 0.3 +/- 0.2, P = .004) than those without diabetes. No changes in sex steroids occurred after the oral glucose challenge. HOMA SI and area under the curve for glucose correlated significantly with SHBG (r = -0.42), non-SHBG-T (r = 0.40), and TC/HDL (r = 0.41) (all P < .05) in the combined groups. Postmenopausal women with type 2 diabetes have both clinical and biochemical evidence of androgen excess that may contribute to more adverse cardiovascular risk profiles.
