Risk factors and risk determinants for the evolution of the diabetic nephropathy in IDDM: a case control study of 108 IDDM patients in the Bucharest Center of Diabetes.

The study included 108 IDDM patients (59 males, 49 females, aged 15-59 years) from the Bucharest Diabetic Centre which participated in the EURODIAB multicentric study. They were divided into three groups according to the duration of diabetes (less than 7 years; 8 to 14 years; more than 15 years) and we have made a comparison between the importance of some risk factors, as elevated blood pressures, age, elevated levels of the total plasma cholesterol, and glycosylated hemoglobin (HbA1C) on the progression of the microalbuminuria in these groups. Excluding the patients in the renal failure stage of the diabetic nephropathy or with other chronic diseases, our results confirm the data in the literature referring to the important role of the elevated diastolic blood pressure and elevated levels of the total plasma cholesterol in the rapid progression of the renal injury, especially after more than 8 years of IDDM evolution. We also found, between the long-term diabetics (over 15 years of evolution) a large proportion which appears to be genetically protected against the diabetic nephropathy. This point confirms some data from the literature (the Steno hypothesis). The HbA1C levels appears to lower with the duration of the diabetes and they are not correlated with the degree of the renal injury. These findings appear to be in contradiction with the data from the literature.

Impaired glucose tolerance in the third trimester of pregnancy: associated factors to its persistence postpartum.

Glucose tolerance (75 g OGTT, according WHO) during the third trimester of pregnancy, in 302 women, has formerly been evaluated. Of these, 37 women were reinvestigated, with the same methodology, in absence of pregnancy and lactation, 2 years postpartum. According to oral glucose tolerance three groups were differentiated: group A (n = 14) with normal glucose tolerance (NGT) both in pregnancy and postpartum. Group B1 (n = 12) with impaired glucose tolerance (IGT) in pregnancy but NGT postpartum. Group B2 (n = 11) with IGT both in pregnancy and postpartum. B2 group had increased values (mean + SD) for age (37.0 +/- 6.6 years) versus B1 (30.2 +/- 5.5; p < 0.02) and A (29.5 +/- 5.9); p < 0.02) groups and BMI (32.5 +/- 4.2) versus 26.4 +/- 5.2; p < 0.01 and 23.3 +/- 4.4; p < 0.001 respectively). The ratio between basal insulinogenic indexes (microU IRI/mg BG) during pregnancy and 2 years postpartum has been significantly reduced in B1 (1.4 +/- 0.8) and B2 (1.5 +/- 0.6) as compared to A (2.5 +/- 1.1; p < 0.01) group suggesting, by comparison, the persistence of an increased level of insulin resistance postpartum in B1 and B2 groups. Insulinogenic index, after oral glucose was lower in B2 (34.4 +/- +/- 7.8) versus B1 (53.5 +/- 20.9; p < 0.01) group. These results suggest that, on an increased insulin resistance background, the decrease in glucose induced insulin response and increase in age and BMI are associated to deterioration of glucose tolerance early in the natural history of NIDDM.

Predictive value of glucose and proteic sulphur levels in the hair for an early detection of the preclinical stage of IDDM.

Assays of glucose and proteic sulphur levels in the hair of patients with recently detected IDDM provided information on the preclinical stage of insulin secretion disorders, which was estimated at 6 +/- 2 months. Such investigations in subjects at high risk of developing an IDDM might reveal the period preceding the disease onset, thus enabling to start an early therapy.

Fear of hypoglycemia in type 1 (insulin-dependent) diabetic patients.

A clinical-psychological study was carried out in 224 insulin-dependent diabetic patients, distributed into two groups according to the frequency of hypoglycemic episodes. Group. A included 124 patients, 65 men and 59 women (mean age 35 +/- 18 years), who reported frequent episodes of hypoglycemia (HG). In the 100 patients of group B (46 men and 54 women with a mean age of 37 +/- 10 years), the HG episodes were only occasional. The degree and type of anxiety were evaluated using: (1) a semistructured interview to determine the HG frequency and intensity; (2) the anxiety scale for HG, with two sections: a) 15 items about the behaviour to prevent HG occurrence and b) 10 items for the anxiety level; (3) the questionnaire of anxiety with 40 items. Highly significant differences between groups were found for the degree of anxiety about HG, particularly for the frequency of high anxiety scores (with ideative ruminations or generalized anxiety, accompanied or not by agoraphobia) (73.86% in group A versus 34.09% in group B; p < 0.001). Relatively significant differences were recorded with respect to the compliance to treatment (preventive behaviour for HG) as well as for the anxiety index (47.95% in group A versus 33.45% in group B), with a prevalence of the covered anxiety in group A and of the overt anxiety scores, indicating a dissimilation tendency of the adaptative role of anxiety as a signal of communication.
