We have studied circulating lipid and lipoprotein concentrations, fasting and over 24 h, in hypopituitary women and men and in matched controls. Firstly, 67 hypopituitary patients (36 women) and 87 normal controls (54 women) were studied after an overnight fast. Secondly, 12 patients (6 women) and 14 matched controls (7 women) were studied over 24 h of normal meals and activity. The patients were all GH deficient and were replaced with cortisol, T4, and sex hormones where appropriate, but not with GH. In the first study, circulating triglycerides, total cholesterol, high density lipoprotein (HDL) cholesterol, and low density lipoprotein (LDL) cholesterol were measured after an overnight fast. In the second study, fasting levels of apolipoprotein B, apolipoprotein A1, and lipoprotein(a) were also measured, and then circulating triglyceride and total cholesterol concentrations were measured over 24 h. Fasting concentrations of triglyceride (mean \u00b1 sem, 1.73 \u00b1 0.22 vs. 1.11 \u00b1 0.09 mmol\/L; P = 0.0025), total cholesterol (6.45 \u00b1 0.25 vs. 5.59\u00b1 0.21 mmol\/L; P = 0.002), LDL cholesterol (4.58 \u00b1 0.24 vs. 3.80 \u00b1 0.19 mmol\/L; P = 0.007), and apolipoprotein B (135 \u00b1 10 vs. 111 \u00b1 9 mg\/dL; P = 0.048) were elevated in hypopituitary compared to control women. The lipid alterations were observed in older and younger women and occurred independently of sex hormone or glucocorticoid replacement. Fasting values were not significantly different in hypopituitary and control men. Patients and controls (women and men) had similar fasting HDL cholesterol, apolipoprotein A1, and lipoprotein(a) concentrations. Although the differences that existed in fasting lipid values were most marked in women, the men were also abnormal in this respect, in that a higher proportion of hypopituitary than control men had total and LDL cholesterol above recommended values (\u22656.2 and \u22654.1 mmol\/L, respectively). In the postprandial period (0730\u20132030 h), the areas under the curve (AUC) for circulating triglyceride and total cholesterol were significantly higher in hypopituitary than control women (P = 0.0089 and P = 0.0016, respectively). The AUC for triglyceride and total cholesterol over 24 h were also significantly increased (P= 0.009 and P = 0.0004, respectively). No significant differences were observed for postprandial and 24-h AUC for triglyceride and total cholesterol concentrations in men. We conclude that hypopituitarism with conventional replacement therapy is associated with unfavorable fasting and postprandial lipid and lipoprotein concentrations, particularly in women. The changes may contribute to the observed increased vascular morbidity and mortality.<\/jats:p>","DOI":"10.1210\/jcem.82.8.4129","type":"journal-article","created":{"date-parts":[[2014,1,8]],"date-time":"2014-01-08T17:02:30Z","timestamp":1389200550000},"page":"2653-2659","source":"Crossref","is-referenced-by-count":1,"title":["Fasting and Postprandial Lipid Abnormalities in Hypopituitary Women Receiving Conventional Replacement Therapy1"],"prefix":"10.1210","volume":"82","author":[{"given":"Kamal A.
