The dynamic of impaired glucose tolerance in women with fetal gigantism.

In a group of 51 women who had given birth to giant children, the glucose tolerance test (GTT) was performed at entry in the study and after intervals of 6 to 12 years. The results of the first determination, estimated according to the WHO's criteria (1980), have revealed an impaired glucose tolerance (IGT) in 7 cases (14%); the second determination showed IGT in 10 cases (20%) and diabetes mellitus in 2 (4%). Insulinemia assays, concomitant with the second performance of GTT, showed the highest values in the diabetic subjects, moderate values in those with IGT, and low values in those with normal glucose tolerance. The presence of obesity in some cases could not be considered as fully responsible for the glucose tolerance impairment in the women with fetal gigantism. The dynamics of glucose tolerance disorders showed variations in time, i.e. the initial pathologic changes were no more recorded on the second testing in the same subjects, while women with normal initial GTT showed high insulinemia or IGT on the second determination.

Characteristics of severe diabetic ketoacidoses occurring before and after 60 years of age.

Between 1978 and 1982, 459 cases of severe diabetic ketoacidosis (pH less than or equal to 7.20, total -CO2 less than or equal to 10 mMol/l) were admitted to our Intensive Care Unit. 416 (241 males, 175 females) were under 60 years (41 +/- 7) and 43 (22 males, 21 females) exceeded 60 years of age (67 +/- 7). The precipitating causes were fairly similar, in both groups, with infections foremost (68%). Presenting biochemical parameters, before and after 60 years showed differences in: blood glucose: 32.7 +/- 12 versus 34.8 +/- 8.1 mMol/l; plasma sodium 137 +/- 14 versus 143 +/- 16 mMol/l; plasma potassium 4.2 +/- 0.9 versus 4.9 +/- 0.7 mMol/l; hydrogen ion concentration 95 +/- 17 versus 73 +/- 12 mMol/l, (p less than 0.01); plasma osmolarity 327 +/- 98 versus 379 +/- 96 mOsm/l. The difference was significant (p less than 0.01) in frequency of hypernatremic hyperosmolarity (initial sodium greater than 147 mMol/l): 7.4% of 202 cases before age 60 years versus 24.1% of 29 case after age 60 years. The fluid amounts administered i.v. within the first 24 h was greater before (7516 +/- 2121 ml; p less than 0.01) than after 60 years (5276 +/- 1132 ml); insulin requirements were greater after 60 years (236 +/- 78 U/24 h; p less than 0.01) than before the age of 60 years (182 + 59 U/24 h). The mortality rate in the course of severe diabetic ketoacidoses was significantly lower before 60 years (1.3%, p less than 0.01) as against 6.9% after age 60 years.(ABSTRACT TRUNCATED AT 250 WORDS)

Albumin to creatinine ratios in early morning samples of urine from healthy persons and patients without clinical proteinuria.

Urinary excretion of albumin was determined in 133 clinically healthy subjects and 236 patients suffering from diabetes mellitus (150 cases), collagen diseases (45 cases), or arterial hypertension (41 cases) in whom there was no clinical or laboratory evidence of renal involvement. Urine albumin was measured by an improved single-radial-immunodiffusion technique and results were expressed as urine albumin to creatinine concentration ratio (mg/g). The geometric mean values in the patients were about 2 to 2.5 times higher than in controls. When considered on an individual basis, at least 40 per cent of the patients had values above the 99th-percentile value for controls. The results suggest that quantitative determination of urinary albumin may be useful for detecting early structural functional alterations of the glomerular filter.

Insulin antibodies in diabetics receiving a single type of insulin.

Insulin antibodies were studied in 77 patients with diabetes mellitus who received a single insulin type from onset of treatment (12 crystalline insulin, 26 Novo Lente insulin, 7 HG insulin, 6 Komb insulin, 5 Long insulin, 17 Monocomponent Semilente insulin, 4 Monocomponent Lente insulin). The mean antibody titers in the patients treated with highly purified preparations were close to those found after treatment with conventional insulins. Correlations are established between the antibody titer and duration of diabetes, insulin requirements, and degree of metabolic stability. The relationship with diabetic complications was difficult to define but not improbable.

A higher level of serum IgA in diabetes mellitus?

On studying the main classes of serum immunoglobulins in four different groups of diabetics, representing more than 400 subjects, the author has noticed that the mean values of IgA are almost constantly raised, irrespective of the clinical parameters analyzed and suggests that this fact should probably be correlated with a change of IgA catabolism.

Behaviour of insulin antibodies in diabetics treated with different insulins.

Determinations of insulin antibodies in 116 insulin-dependent diabetics treated successively with various types on insulin and in a group of 55 diabetics who received a single insulin type from the onset of the disease, revealed higher titers in those under treatment with conventional insulins, particularly Insulin Novo Lente. The mean titer of insulin antibodies is considered to be related to the insulin demands and sometimes to the length of disease. The presence of antibodies was also recorded after administration of highly purified insulins, but much more seldom and with lower titers, which could be an argument for a wider utilization of such products.

Data processing system for the Centre of Nutrition and Metabolic Diseases.

The paper is devoted to the functional specification and the architecture of a data processing system to database generation and management within the Centre of Nutrition and Metabolic Diseases in Bucharest. The main operations performed by the system refer to: --Patient admission. A patient file which is created for any new patient, contains all the details hitherto included in the patient registration form. --File update, carried out periodically or whenever required. Any new relevant detail is added to the existing file in a conversational manner. --Report generation. The reports are produced periodically or upon request. --Inventory and stock control concerning the drugs dispensed free of charge. --Data processing and classification. --Creation and retrieval of patient archives. --Display on request of the various details contained by the patient file. The described system can be implemented on an INDEPENDENT I-100 general purpose minicomputer, having a main memory of 96 kwords. The disc-based AMS operating system is used. The system operates in real time, although off-line background jobs can be run in order to assist the scientific work. A FORTRAN compiler is part of the operating system.

Immunoglobulin A in diabetics.

Serum immunoglobulins G, A and M were investigated by radial immunodiffusion in a group of 217 diabetics (133 males, 84 females) of whom 152 were insulin dependent and 65 non-insulin dependent. Higher values of IgA as compared with IgG and IgM were observed whatever the criteria of clinical analysis used. The highest IgA values were found in diabetics aged over 65 at the onset of disease and in those with renal complications.

Study of some serum protein fractions in various clinical forms of diabetes mellitus.

With a view to studying the eventual alterations of protein metabolism, some serum protein fractions such as: immunoglobulins (IgG, IgA, IgM), transferrin and ceruloplasmin were determined in 100 diabetics (52 males, 48 females) in comparison with a control group of 26 healthy subjects. Significant differences were found between IgA and transferrin values both in diabetics and in controls. IgA tended to increase with the length of disease, whereas IgG, IgM and transferrin showed a contrary trend. IgA and transferrin values were higher in the patients with juvenile and young adult diabetes, as compared to maturity onset and senile diabetes. Other immunoglobulin and transferrin changes were related to sex, age, type of treatment, degree of stability, presence of chronic complications. No significant anomalies were found for ceruloplasmin. The results confirm the presence of serum protein alterations in diabetes mellitus, whose significance may be correlated with the clinical particularities of the disease.

HBs antigen and blood glucose concentration.

HBsAg presence was studied by counterelectrophoresis (CEP) in 76 patients with liver cirrhosis and in 431 patients with diabetes mellitus. A striking correlation was found between high blood glucose values and HBsAg absence. Thus, HBsAg-negative cirrhotics (53%) had significantly higher levels of glycemia than the HBsAg-positive patients of the same age group, i.e. 95.75 +/- 6.36 ng/100 ml compared to 78.30 +/- 10.2/100 ml. This absence of HBsAg was also observed in all diabetics but one. As the incidence of HBsAg (CEP) was found to be of 3.63% in 253,460 subjects from different areas of Romania and 6.84% in 14,690 subjects with various non-hepatic diseases included, the chance of finding the 0.2% HBsAg incidence observed in the diabetics would be less than 0.0002 and 0.0001, respectively. The serum HBsAg absence in cirrhotics with high glycemia and in diabetics strongly incriminates the constant high concentrations of blood glucose as the main factor responsible for this negativity. The effect may be direct on virus replication, or indirect, by metabolically-induced hepatic dysfunction interfering with HBsAg secretion or excretion. The presence of high concentrations of glucose in cell culture media might explain the repeated failure of hepatitis B virus serial passage in tissue or organ culture.

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.
