Study of pituitary secretion in relation to retinopathy in patients with juvenile diabetes mellitus.

Fifteen juvenile diabetic patients with normal eye fundus, 6 with non proliferative retinopathy, 5 with proliferative retinopathy and 5 healthy control subjects were studied in order to investigate pituitary function in relation to diabetic retinopathy. ACTH values at 08(00) and 18(00), hPRL and TSh secretion in response to 200 microgram TRH i.v., and GH secretion in response to 500 mg oral L-dopa were evaluated. In all diabetic subjects, 08(00) ACTH levels were lower than in controls. Basal hPRL, TSH and GH values of the diabetics did not differ from those of the controls. No significant differences were found in hPRL levels in response to TRH, whereas significantly lower TSH responses were found in the diabetics. L-dopa caused a significantly different response of GH in the diabetic subjects compared to controls. There is thus a considerable derangement in pituitary hormone secretion in juvenile diabetics mellitus.

Vitiligo and juvenile diabetes mellitus.

Five juvenile diabetics had vitiligo. In two children, the vitiligo preceded the onset of diabetes. Four of the five patients had thyroid, adrenal, or gastric antibodies or a combination of these. In three children HLA-B8 antigens were detected, and one additional patient had HLA-Bw15. Of eight nondiabetic children with vitiligo, one had abnormal glucose tolerance. To the evidence supporting an autoimmune form of diabetes mellitus we add another observation: the association of insulin-dependent diabetes and childhood vitiligo.

Plasma insulin during remission in juvenile diabetes mellitus.

Three juvenile diabetics in partial remission were studied before and after the recurrence of overt diabetes. The remissions were partial because glucose tolerance never returned to normal. However, it improved sufficiently to cause the discontinuance of insulin therapy for at least four months.The insulin output in response to double glucose tolerance tests was increased during remission. The degree of remission seemed to be related to the magnitude of the insulin response to glucose. In two of the patients the increase was low and the response very slight. The third patient, however, had a delayed hyper-response and his carbohydrate tolerance during the remission was much more improved than those of the other patients.

HLA-Dw2 as a marker of resistance against juvenile diabetes mellitus.

Juvenile-onset diabetes mellitus (JDM) is one of the human diseases shown to be associated with histocompatibility antigens. The occurrence of serologically defined HLA antigens B8 Bw15, B18 and Cw3 is increased among these patients (Singal & Blajchman 1973, Nerup et al. 1974, Cudworth & Woodrow 1975). However, lymphocyte defined HLA-D antigens Dw3 and Dw4 (LD 8a and LD w15a), positively associated with these serologically defined antigens, seem to be even stronger markers of susceptibility to this disease (Thomsen et al. 1975).

Glycosylated hemoglobins and their relation to the control of juvenile diabetes mellitus.

Patients with juvenile diabetes mellitus were studied over a period of six months. During this time their metabolic control was classified and the relation between the blood concentration of the glycosylated hemoglobins Hb A1a + b + c and the degree of diabetic control was established. 12 out of 37 diabetic children were under good control, whereas 6 patients were poorly controlled. Well controlled children had low concentrations of glycosylated hemoglobins, within the range of non-diabetic subjects. Those under poor control showed an almost twofold increase of the concentration of these minor hemoglobins. Hb A1a + b + c levels of 8 newly diagnosed diabetics were also extremely elevated. Since the hemoglobin-sugar linkage is irreversible, these components remains much longer elevated than the blood glucose itself. It is concluded that the determination of Hb A1a + b + c levels is a valuable tool for the evaluation of the efficiency of diabetic therapy in addition to blood and urinary glucose measurements.

Etiologic variability of nephropathy in juvenile diabetes mellitus.

Clinicopathologic studies of four patients with juvenile diabetes mellitus and renal disease demonstrated the pathogenetic variability of nephropathy in diabetic patients. Only in one patient was the clinical nephropathy associated with the typical diabetic glomerulosclerosis. Another patient had steroid responsive nephrotic syndrome superimposed on minimal diabetic glomerulosclerosis. A third patient had steroid resistant nephrotic syndrome associated with mild diabetic glomerulosclerosis and with later appearance of Grave's disease. The fourth patient, in addition to moderate diabetic glomerulosclerosis had prominent tubulointerstitial nephritis, the latter probably being responsible for the rapidly declining renal function. The poor prognosis associated with diabetic nephropathy warrants a careful search for other potentially treatable causes of nephropathy in patients with juvenile diabetes mellitus.

HLA and insulin-dependent juvenile diabetes mellitus.

The typing of 22 HLA-A and B antigens in members of 13 families with one child having juvenile diabetes mellitus showed a statistically significant higher frequency of HLA-B8 antigen in sick children (51.54%) as well as high parental heredity rate of this antigen, as compared to 301 normal subjects and 51 normal children of families free from diabetes mellitus. The agreement of 85.71% in one or two haplotypes in diabetic and healthy siblings in 7 families involved antigens other than B8. The results of these family studies confirm the existing relationship between HLA-B8 and juvenile diabetes mellitus as demonstrated by repeated screenings of the patients populations. The relationship of HLA antigens to insulin-dependent juvenile diabetes mellitus has been studied by many authors. The issues of their studies on patient populations revealed HLA-DR3, Dw3, DR4, Dw4, B8, B18, B15, B40, Cw3 and secondarily A1 and A2 to occur with significantly higher frequency. On the other hand, antigens DR2, Dw2, B7 (secondarily A3 and A11) are statistically less frequent in this disease, and their presence therefore means a certain protection against the risk of diabetes (4, 6, 7, 11, 15, 21). Individual authors' family studies differ in conclusions as to the occurrence of some of the above HLA antigens, and the degree of HLA identity of two siblings, one with diabetes, the other one normal (6, 8, 12, 17). For this reason we decided to start investigations on the occurrence of HLA A and B antigens in family members with one child having juvenile diabetes mellitus.(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship between periodontitis and tooth decay in juvenile diabetes mellitus cases and in healthy children.

Children diagnosed as having juvenile diabetes mellitus have been compared with healthy children of the same age, with respect to decayed, filled primary teeth (df), decayed, missing, filled permanent teeth (DMF), Gingival index (GI), Periodontal index (PI), Oral hygiene index (OHI). These parameters have been evaluated according to WHO criteria. Corresponding parameters have been statistically evaluated. When experimental and control groups were compared statistically, a highly significant difference was seen between df and DMF indexes of diabetic and healthy children. In the periodontal evaluation, a significant difference was found in the gingival index, but no such significance was seen in the periodontal index. From the results of this study it can be seen that children with juvenile diabetes mellitus had less caries incidence compared with the control group. Even though gingival destruction had already started in this study group, intense periodontal damage was not observed at this particular age level.

Studies on the frequency and associations of islet-cell antibodies in juvenile diabetes mellitus.

Ninety-six juvenile onset type diabetics showed an increase in the frequency of HLA B8 and B15 and a decrease in frequency of HLA B7 antigens. Sixty-four maturity onset diabetics showed no disturbance in the frequency of these antigens. Fifty-four of the juvenile onset type diabetics, with an average duration of disease of 3.2 years were tested for the presence of islet cell antibodies (ICAs). Thirty-two percent were positive, the frequency decreasing from 70% in those patients tested within one year of diagnosis to 0.5% in those patients tested more than 5 years after diagnosis. No correlation was found between HLA type and the frequency of ICAs, but there was an increase in other autoantibodies in B15 positive patients. Preliminary absorption studies suggest a cross reactivity of ICAs and Coxsackie B4 virus.

Juvenile diabetes mellitus.

Population studies in Israel have shown that Jews born in Europe or America have the highest prevalence of juvenile diabetes mellitus and Jews born in Asia or Africa, the lowest. The rate in the Israel born, regardless of the father's place of birth, is intermediate between those of the other two groups. The rates for the group from Europe/American and for the Israel-born group increased during the years 1963-68, while that for the Asia/Africa group did not change. It is speculated that the differences in the rates of juvenile diabetes mellitus are related to different frequencies of certain HLA antigens in the different groups or to different associations with susceptibility genes to juvenile diabetes.

Juvenile diabetes mellitus in Ethiopians.

The clinical features seen in 27 Ethiopian juvenile diabetics, which were similar to those of juvenile diabetics elsewhere, are summarized in this first published report from an African country of childhood diabetes. Control was difficult and admission to hospital frequent because of poverty, uncontrolled diets and irregular supplies of insulin. This group of childhood diabetics represents 9.8% of patients attending a diabetic clinic in Addis Ababa. Survey of the published information on diabetes mellitus in African populations reveals that most series do contain several children and a significant number of teenagers. It is concluded that juvenile diabetes mellitus is not rare in African countries.

Juvenile diabetes mellitus after forty years.

Seventy-three patients with juvenile diabetes mellitus for a mean duration of 42.9 years were retrospectively studied on a multidisciplinary basis. Only three of this group of patients were socially disabled as a result of their long-standing illness. Of all the complications, insulin-induced hypoglycemia was most common. Although diabetic retinopathy was clinically evident in about 75 per cent of patients, only 50 per cent of these seventy-three patients had a significant visual impairment. Nephropathy was apparent in 59 per cent of patients, and neuropathy was demonstrable in half of them. Significant peripheral vascular system impairment was present in 40 per cent and major cardiac complication in 20 percent.
