Insulin sensitivity and insulin secretion in lean and obese normal pregnant women.

An insulin-modified frequently sampled intravenous glucose tolerance test with minimal model analysis was performed in normal pregnant women between 28-32 weeks of gestation, to assess insulin sensitivity and insulin secretion. Insulin sensitivity in the pregnant group (no. 26) was reduced to approximately 50% that of nonpregnant group (no. 27) (p < 0.05). This increased insulin resistance was compensated by an enhancement of the first phase of insulin secretion, which was increased more than twofold in the pregnant women when compared with the nonpregnant women (p < 0.05). There was a trend toward greater insulin resistance and insulin secretion in the obese pregnant women (no. 7) as compared with the lean pregnant women (no. 19) although this difference was not statistically significant. Our findings confirm that late pregnancy is a state of physiologic insulin resistance compensated by an increase of insulin secretion.

[Pancreatic transplantation].

The AA. report on their very limited experience with whole pancreatic transplantation. For the moment this is the only experience in Portugal, the detailed report of the 3 cases may be of some help to other Portuguese groups interested in starting this therapeutical approach for insulin-dependent end-stage renal failure patients. The main comments focus on the third simultaneous pancreas-kidney transplantation, which failed for technical reasons, mainly related to less than good selection of both donor and recipient. In all the three cases the technique preferred was the duodenocystostomy. The 2 first cases are doing very well, free of insulin and with normal glucose metabolism, at 15 and 7 months after grafting. The AA. also make some considerations on the indications, complications and follow-up of patients with pancreas-kidney transplantation.

[Hypoglycemia].

With near optimal metabolic control, in diabetes mellitus, hypoglycaemia has become a very important problem. Its main causes are excessive insulin or sulfonylurea dosages, omission of meals, unprogrammed physical exercise or disturbances of the neurohormonal counterregulatory mechanisms.

[Acute thyroiditis].

We review the pathophysiology, clinical features and therapy of acute thyroiditis. Four cases are reported stressing the role of fine needle aspiration for the diagnosis of this clinical entity.

[Beneficial effects of added glicazide in patients with type II diabetes mellitus treated with insulin].

The aim of the study was to assess, in patients with non insulin dependent diabetes mellitus (NIDDM), either with previous failure to sulphonylureas or insulin treated since the disease started, if the combination of gliclazide to insulin therapy might induce a reduction of daily insulin requirement. 30 caucasian type II patients used to self-monitoring (11 female, 19 male, mean age 55.78 +/- 8.07) with residual pancreatic function (glucagon induced C-peptide release = 1.01 +/- 0.70 microgram/ml) entered the study. 8 were excluded for non compliance or for high antiinsulin antibodies levels and 4 are still under study. Each patients was given, for 3 months, 240 mg of gliclazide in addition to usual daily dose of insulin. Data presented as mean +/- s.e.m. were analysed with analysis of variance (p less than 0.05). Mean initial values of main parameters were as follows: glycaemia 192.7 +/- 33.1 mg/100 ml, insulinaemia 9.5 +/- 4.5 microUI/ml, daily insulin requirements 33.11 +/- 10.47 U/d, HbA1 C 7.5 +/- 1.7%. Total cholesterol 240.1 +/- 52.2 mg/10 ml, triglycerides 120.6 +/- 60.3 mg/100 ml. After 3 months treatment significant reduction in mean daily insulin requirements (20.78 +/- 16.15 U/d) was observed. In 13 patients (72.2%) while keeping good metabolic control (HbA1 C 7.46 +/- 1.63), insulin therapy was reduced (9 patients) or even stopped (4 patients). In the other 5, insulin was maintained or slightly increased. The increase in glucagon induced C-peptide release (1.41 +/- 0.99 micrograms/ml) did not reach significance, while glycaemia and insulinaemia were not changed (196.0 +/- 34.1 mg/100 ml, 11.02 +/- 5.05 microUI/ml).(ABSTRACT TRUNCATED AT 250 WORDS)

[Pregnancy and endocrinopathy. Activity, pathology and results at the outpatient obstetrics-endocrinology clinics of the University of Coimbra Hospitals--January 1980 through December 1988].

The authors have elaborated a statistic survey about the pregnant women with endocrinopathies, that they have examined in the outpatient clinic from January of 1980 to December of 1988. Three hundred and twenty four women were examined in an amount of 2152 (two thousand one hundred and fifty two) observations. The incidence for 100 births was 0.54%. Maternal and fetal mobility and mortality were analysed in correlation with the maternal area of endocrinopathy (Diabetes Mellitus, Thyroid, Hypophysis and Adrenal Glands) and with the necessary therapeutic regimens. At last the A.A. made some considerations about the importance of a team approach in this area of medical care, and applied to the clinicians who work in primary care, to a better collaboration.
