When pathophysiological and pathogenetic aspects of hypertension are taken into consideration with special regard to diabetes mellitus the exhaustion of the "insulin enhancement" within the cerebrovisceral functional systems (Baumann) are discussed and the authors enter possible connections of diabetes mellitus to the renin-angiotensin-aldosterone system. After explanation of the diabetogenic and antidiabetogenic pharmacodynamic qualities of the antihypertensive drugs adequate therapeutic recommendations are proposed summarized in a figure. The authors conclude that for the present antihypertensive therapy in diabetics taking into consideration the references reported on there are sufficient possibilities of treatment for all degrees of severity of hypertension. Such preparations as Rausedan, Disotat, Dopegyt appear as particularly suitable; moreover, the beta receptor blockers, Haemiton, Depressan as well as Guanitil and Pargylin prove to be possible or without disadvantage, respectively. Especially when diuretics are described an exact control of the metabolism should be carried out.

In experiments on the isolated superior cervical sympathetic ganglia of rats with alloxan diabetes rhythmic stimulation of preganglionic nerves was effected; summation presynaptic spikes and EPSPs of ganglionic neurons were registered. In rats with moderately severe alloxan diabetes progressive depression of rhythmic ganglion potentials was connected with suppression of the mediator emission to the impulse due to rapid exhaustion of its operational fraction. Rats with severe diabetes displayed also postsynaptic suppression of the ganglionic neurons. Dynamic characteristics of the transmitter turnover assessed on the basis of consideration of the successive patterns of posttetanic potentiation showed insignificant changes in the mediator output and a significant (by 38%) suppression of the mediator reserve per sec in comparison with control.

The therapy of gout is discussed taking into consideration the concomitant diseases occurring significantly frequently in patients with gout: Hypertension, uric acid-nephrolithiasis, hyperlipoproteinaemia, obesity, premature arteriosclerosis as well as diabetes mellitus. In contrast to other opinions the authors are of the opinion that the dietetic treatment is furthermore of essential importance. It is referred to the still allowed sufficiently great number in the supply of nourishment, in which cases, however, the limitations in the supply of calories, protein or purin bodies, respectively, lipid and carbohydrate do not remain unmentioned. The propositions for the medicamentous treatment essentially correspond to the central therapeutic recommendations. For the acute attack of gout, however, following to the international experiences, the colchicine therapy is more emphasized again. The medicamentous therapy of the asymptomatic hyperuricaemia is to be included into the considerations after full exhaustion of all dietetic and other possibilities in constant increase of the serum-uric acid-level more than 8 mg/dl.

The contribution of proinsulin to the total serum immunoreactive insulin (IRI) was measured in 59 patients with maturity onset diabetes (23 being treated with diet alone and 36 with oral sulfonylurea agents) and compared to that in 44 control subjects. The percentage of proinsulin was increased in 11 patients and correlated with plasma glucose, but not with IRI. There was no difference between the drug-treated group and diet-treated group, or between patients taking different sulfonylurea agents. Sequential studies in one patient showed normalization of the proportion of proinsulin following lowering of the plasma glucose level. It is probably that the increased circulating proportion of proinsulin in hyperglycemic diabetic patients is secondary to beta cell exhaustion with release of less mature granules.

"Essential labile diabetes" is an insulin-dependent diabetes, in the course of which irregular and unpredictable hyperglycemias, frequently with ketosis, and sometimes serious hypoglycemias alternate. In spite of careful treatment with insulin, diet and suitable hygienic measures, this form of diabetes cannot be influenced. Fortunately, it seldom occurs, not more frequently than in 1 to 2% of diabetics. Various attempts have been made to explain the pathogenesis of this form of the disease. The most probable explanation is that there is an almost complete exhaustion of insulin secretion. This hypothesis is based on the extremely low level of the C peptide below 0.60 ng/ml, whereas in non-labile insulin-dependent diabetics the C peptide amounts to more than 2.2 ng/ml

Complex clinical and laboratory research of nonspecific immunobiological reactivity was conducted in 86 children (35 with diabetes mellitus, 25 with obesity, and 26 healthy children), aged from 3 to 14 years. Lysozyme activity and complement titre were studied during the disease. Reduced reactive possibilities of the organism were demonstrated in diabetic children; reduction of these parameters was directly proportional to the severity of the main process and the extent of decompensation. In obese patients the parameters of nonspecific reactivity tests were higher than in healthy children, and glucose tolerance was disturbed; this was apparently connected with stress of the compensatory-defense mechanisms of the organism. A distinct reduction of the parameters in this group of children under the effect of unfavourable factors pointed to exhaustion of the compensatory mechanisms. Obese patients should be referred to the group of children will increased risk, both in respect to diabetes mellitus and to other diseases. The indices under study could be applied as tests characterizing not only the immunobiological reactivity and the defense-adaptive mechanisms of the organism, but also the severity and phase of the disease.

The conception of a specific association between maturity-onset diabetes and manic-depressive psychosis, on a common basis with diencephalic functional obesity, has been recently taken again in consideration by the psychiatric literature. Investigations on this problem from diabetological point of view have been so far completely lacking, and are proposed with the present study. Symptomatic depressive conditions in diabetes are frequent and should be primarily separated from depressive endogenous psychosis. The pathogenesis of the association between diabetes of the adult-obese type and psychosis might be discussed according to a transactional theoretical model, assuming a positive feed-back mechanism of the two relationships: diabetes-psychosis and psychosis-diabetes. With these criteria, 4 observations of the clinical association were collected out of 274 admissions for diabetes, during 1976. Diabetes is intended as overt diabetes; obesity presented with the stenic picture; psychosis had a monopolar melancholic course. Similar clinical features were characteristic in all cases. The relationship diabetes-psychosis showed no evidence, unless importance should be given to a potential diabetes in 3 cases. On the contrary, the relationship psychosis-diabetes could be demonstrated in the four cases. A psychosomatic scheme connecting the neuro-hormonal correlations to a genetically conditioned exhaustion of the beta-function, is postulated. During melancholic recurrences, diabetes proved to be insulin-dependent and even insulin-resistent in 2 cases. Tricyclic antidepressant theraphy did not modify the metabolic situation.

Glycerol, an effective cerebral dehydrating agent, also has gluconeogenic properties, and can thereby elevate serum glucose to dangerously high levels in predisposed patients treated for cerebral edema. The nonketotic hyperosmolar hyperglycemic state usually occurs in cases of maturity onset diabetes or prediabetes, as in the two elderly patients discussed in this paper. The pathogenesis usually evolves through a constant diabetogenic stress that causes persistent hyperglycemia resulting in the exhaustion of ordinarily adequate insulin stores, ultimately allowing hyperglycemia to progress unchecked to metabolic coma. Precautions to recognize this development should be taken in appropriate patients.

In 30 diabetics and their nearest relations (44 persons) the immunoreactive insulin (IRI) was examined and a routine glucose tolerance test was carried out as well as in patients with ischaemic heart disease (more than 100 patients). The control group consisted of 30 healthy volunteers. An analysis of the results was performed taking into consideration the degrees of severity and the duration of the diabetes as well as the age of the patients. A conclusion was drawn that the exhaustion of Langerhans islets occurs relatively early during "juvenile" diabetes. A clear decrease of the IRI corresponding to the degree of severity and to the duration of diabetes can be observed. In the nearest relations of the diabetics a normal IRI-level and in a relatively little percentage latent forms of a diabetes were detected. In patients with ischaemic heart disease however, the non-manifest forms of diabetes were by far more frequent. It is considered that more precise tests should be applied in laboratory diagnosis of latent diabetes mellitus in hereditarily aggravated persons in the mentioned respect.

Serum C-peptide, insulin-binding IgG and total insulin (IRI) were determined in 96 juvenile diabetics aged 4-21 years, with onset of diabetes at the age of 1-16 years and with 2-17 years' duration of diabetes. Thirty-four patients (35.4%) had detectable levels of C-peptide (greater than or equal to 0.04 pmol/ml). Compared to non-diabetic adults, 19 had values below the normal range, 12 showed values within the normal range (0.18-0.63 pmol/ml) and 3 rated above normal. There was a negative correlation between the fasting C-peptide concentration and the degree of ketonuria at the onset of diabetes and a positive correlation between C-peptide levels and the incidence of post-initial remission periods. Patients without detectable C-peptide had significantly higher levels of insulin antibodies than those who had detectable levels of C-peptide. The possibility of a relationship between the intensity of the initial treatment of diabetes and the preservation of the B-cell function is discussed, as well as the possibility of insulin antibodies being a cause of B-cell exhaustion.
