OBJECTIVE: In the present study, we evaluated whether the coefficient of variation (CV) of fasting plasma glucose (FPG) over a 3-year period was a significant predictor of mortality in type 2 diabetic patients aged 56-74 years. RESEARCH DESIGN AND METHODS: All type 2 diabetic patients (n = 1,409) aged 56-74 years attending the Verona Diabetes Clinic and having at least two FPG determinations in each of the years 1984-1986 were followed for 10 years (1987-1996) to assess total and cause-specific mortality Patients were grouped into tertiles of mean and CV of FPG during 1984-1986. These parameters as well as sex, age, diabetes duration, insulin treatment, smoking, hypertension, and hypercholesterolemia were included in multivariate survival analyses. RESULTS: During the follow-up, 468 patients died. The CV of FPG was an independent predictor of total, cardiovascular, and cancer mortality. Mean FPG was a predictor of total mortality only when the CV of FPG was not included in the analyses. CONCLUSIONS: Long-term variability of fasting glucose is an independent predictor of mortality in patients with type 2 diabetes. The CV of FPG might be considered a useful additional parameter in the management of these patients.
[125I]Insulin binding to insulin receptors on circulating monocytes was studied in 9 patients with acromegaly associated with fasting hyperglycemia and was compared to previously reported studies of 11 patients with acromegaly who had normal or nearly normal glucose tolerance and 29 normal volunteers. In the hyperglycemic acromegalic, as had been found in the normoglycemic acromegalic, the total receptor concentration per cell was decreased in proportion to the hyperinsulinemia, i.e. the receptor concentration was inversely related to the basal level of insulin, similar to what is found in patients with obesity, diabetes, and insulin-secreting tumors. However, the acromegalic patients with hyperglycemia failed to show the increase in affinity of the empty receptor that had previously been found in their normoglycemic counterparts. The failure to increase receptor affinity causes the cells of the hyperglycemic acromegalic patients to bind less insulin at each insulin concentration than do the cells of normoglycemic patients. Again, the abnormalities in the patients correlates very closely with abnormalities at the level of the insulin receptor, though the sequence of the molecular events that produce these changes remains to be determined.

The aim of this study was to study the efficacy and safety of long-acting insulin analog insulin lispro protamine suspension (ILPS) in diabetic pregnant women.In a multicenter observational retrospective study, we evaluated pregnancy outcome in 119 women affected by type 1 diabetes and 814 with gestational diabetes (GDM) treated during pregnancy with ILPS, compared with a control group treated with neutral protamine hagedorn (NPH) insulin.Among type 1 diabetic patients, fasting blood glucose at the end of pregnancy was significantly lower in ILPS-treated than in NPH-treated patients. HbA1c levels across pregnancy did not differ between groups. Caesarean section and preterm delivery rates were significantly lower in the ILPS-women. Fetal outcomes were similar in the ILPS and NPH groups. Among GDM women, fasting blood glucose at the end of pregnancy was significantly lower in ILPS-treated than in NPH-treated patients. Duration of gestation was significantly longer, caesarian section and preterm delivery rates were lower in the ILPS-treated group. In addition, there were significantly fewer babies with an excessive ponderal index or neonatal hypoglycemic episodes in the ILPS group than in the NPH group.Association of ILPS with rapid-acting analogs in pregnancy is safe in terms of maternal and fetal outcomes.
Background: Thyroid remnant ablation of differentiated thyroid carcinoma (DTC) patients is traditionally performed after levothyroxine withdrawal. Recombinant human TSH (rhTSH) administration increases serum TSH levels without inducing hypothyroidism.
Key Clinical Message Addison Disease is an uncommon, life‐threatening condition affecting people at any age, including women during pregnancy. If left untreated, the disease can be rapidly fatal, but the prognosis is good if promptly recognized and hormones are replaced.
