Controlled study comparing treatment with monocomponent insulin and conventional insulin in patients with lipoatrophy.

Twenty-one patients with evident lipoatrophy treated with conventional (Conv.) insulin were either allocated to continuation of treatment with previously used insulin (Conv. group, n = 10) or were transferred to Lente MC (monocomponent) insulin with or without supplementary Actrapid MC insulin (MC group, n = 11). On entry and after 3, 6 and 12 months of follow-up, serum insulin-, pancreatic polypeptide- and proinsulin-binding IgGs were determined by radioimmunoelectrophoresis according to the method of Christiansen. Prior to determination of proinsulin-binding IgG, the insulin-binding IgG was removed by means of sepharose-bound insulin according to the method of Heding. In both groups a slight decrease in the titer of insulin-binding IgG was observed: in the Conv. group from 5.33 +/- 0.92 (SEM) to 4.66 +/- 1.17 mU/ml after 12 months, and in the MC group from 3.22 +/- 0.64 to 2.66 +/- 0.46 mU/ml, respectively. Due to the small number of patients with pancreatic polypeptide antibody titers above the detection limit no statistical evaluation was carried out. The level of serum proinsulin-binding IgG decreased in the MC group only (from 9.3 +/- 2.2 to 1.9 +/- 0.6 ng/ml after 12 months), and even showed a slight increase in the Conv. group (the respective titers were: 14.0 +/- 4.6 and 14.9 +/- 4.6 ng/ml). In the MC group 10 patients (91%) showed improvement and 7 (64%) complete regression of their lipoatrophy corresponding to 6 (60%) and 2 (20%) in the Conv. group. This finding suggests a possible role of proinsulin-binding antibodies in the pathogenesis of insulin lipoatrophy.

Clinical course of myocardial infarction among diabetic patients.

The clinical course of myocardial infarction (MI) was compared between 154 known diabetic (Ds) and nondiabetic (NDs) MI patients matched for age, sex, and hospital ward. In both groups similar numbers of cases with cardiac rupture, shock, pulmonary edema, and clinically observed arrhythmias were found. In contrast, Ds patients had significantly more frequent A-V and intraventricular conduction disorders than NDs (P less than 0.02). Ds also died twice more often from MI (36%) than matched controls (18%). The excess case fatality rates from MI among Ds were limited to the period between the second and seventh day of hospitalization. The excessive fatality of Ds from MI resulted mainly from the high liability of insulin-dependent diabetic patients (IDDs), with the relative risk of over 4 in relation to NDs. Ds with arrhythmias and/or conduction disorders had a particularly poor prognosis for surviving, the relative risk exceeding 3. No ready explanation of this phenomenon is presently available.

The role of circulating glucose and triglyceride concentrations and their interactions with other "risk factors" as determinants of arterial disease in nine diabetic population samples from the WHO multinational study.

In 9 of the 14 national samples of diabetic patients assembled for the WHO Multinational Study of Vascular Disease in Diabetes additional laboratory data made it possible to relate manifestations of macrovascular disease to blood glucose concentrations as well as to diabetes duration and to other potential determinants. In five of the samples, serum triglyceride concentrations were also measured and were included in simple and multivariate analyses. Ischemic heart disease defined from Minnesota-coded EKGs and standardized WHO questionnaires was more strongly associated with serum triglyceride concentrations than with serum cholesterol concentrations, an association less notable in non-insulin-dependent diabetic patients. Ischemic heart disease was not related to the single fasting plasma glucose estimated for this study. Stroke and amputation were much more strongly related to the known duration of diabetes than was ischemic heart disease, and they were both related to blood glucose concentration measured at the time of study. Despite major variation in arterial disease prevalence rates between collaborating centers, risk for diabetic women appeared to equal that for diabetic men. The major variation in arterial disease prevalence between national groups could be accounted for only in part by the risk factors studied. Other factors, genetic or more likely environmental, are likely to contribute to the variation in arterial disease susceptibility and, if definable, may be potentially preventable.

[Factors determining the presence and predicting the development of diabetic retinopathy].

In a group of 329 diabetics aged 35-56 years with diabetes duration 1-30 years 134 cases were found diabetic retinopathy (40.7%). After 7 years funduscopy was repeated in 136 out of 248 patients and 50 new cases of retinopathy were disclosed. After multivariate analysis it was found that retinopathy was associated most closely with diabetes duration, while arterial hypertension was most surely predicting during 7 years future retinopathy, particularly in the case of higher level of glycosylated haemoglobin at the final examination.
