HL-A antigens were determined in 100 patients with diabetes mellitus. When the data are combined with that from other studies, there is a definite positive association of acute-onset juvenile diabetes mellitus with HL-A8 and W15. Four families are described in which two or more members with this type of diabetes are present, and in each family, affected individuals share a haplotype including HL-A8 or W15. These findings are consistent with the possible role of immune response genes in the HL-A chromosomal region which might control the immune response to virus infections capable of producing islet cell damage.

A group of eight infants with a disorder termed the IDD syndrome and another group of eight matched healthy infants taken into study at the same time have been followed-up for 6.75 years. The follow-up technique and some findings are described. Three IDD syndrome children are still severely disturbed. Three others show recovery from severe developmental disturbance. But one child who was grossly abused after being taken into the study has been well since the third follow-up. The comparison children have not experienced comparable problems. A qualified affirmative to the question of predictive power is given and discussed.

In view of the reported variation in the association between HLA antigens and Juvenile Diabetes Mellitus (J.D.M.) among different Caucasian populations, we have undertaken a study of these antigens among 44 Caucasian Newfoundlanders and 135 matched controls. We have also studied the allotypic markers for Immunoglobulin G (Gm) and variants of C3 among 36 of these patients. We found that both HLA--B8 and B15 were increased among the patient group, resulting in a relative risk of 3.9 and 4.4 respectively. While these values are the highest to be described for J.D.M. among Caucasians, and fell outside the 95% confidence intervals for the combined relative risk calculated from published series, it is still possible that they can be accounted for by sampling. The combination of the two antigens increased the relative risk for J.D.M. in an additive fashion. Additionally, we also found that the combination of HLA B8 and B18, but not B15 and B18, also appear to act in an additive manner. The incidence of Gm allotypes and variants of C3 were not different in the J.D.M. group from those observed among controls.

Islet-cell deterioration in juvenile diabetes mellitus may be due to an autoimmune reaction, possibly involving both circulating islet-cell antibodies and an inflammatory process in the islets of Langerhans. Replacement of deteriorated islet cells by implantation of normal ones is now under investigation in many laboratories. The present study does not support the assumption that such islet transplants should be affected in the same way as the endogenous islets. Diabetic mice with a cell-mediated immune reaction to their pancreatic islets, induced by repeated injections of low doses of streptozotocin, were used as recipients. Isogeneic islets implanted intrasplenically in these animals were as effective in producing normoglycaemia as were those injected into animals made diabetic with a single bolus dose of streptozotocin. No inflammatory reaction was seen in the implanted islets, irrespective of the regimen of the preceding streptozotocin treatment. This finding suggests that islet-cell implantation may be attempted in insulin-requiring diabetic patients, even if the cause of the disorder is an inflammatory lesion of the patient's own islets.

1451 patients with IDDM, onset before 1953 and before the age of 30 were followed until death or until 1976. Survival with diabetes, relative survival and the influence of supervision on survival were examined. It is shown that only 50% of the patients survived more than 30 diabetes years. The patients had an overmortality of more than 600% in relation to age and sex matched non-diabetics. Frequent supervisions in the out-patient clinic reduced as well the overmortality as the prevalence of severe complications significantly.

Combined renal and pancreatic transplantation in patients with juvenile diabetes mellitus, diabetic nephropathy and renal insufficiency is designed to improve the poor prognosis observed with hemodialysis or renal transplantation alone. Interest has recently shifted from pancreatic organ to islet transplantation, in view of the absence of complications with the latter. However, no permanent success with islet transplants in diabetic patients has so far been reported. In the series presented, one patient with juvenile diabetes and subsequent renal failure was successfully treated with simultaneous kidney and intrasplenic pancreatic islet allotransplants. One year after the operation the patient has normal blood glucose levels without exogenous insulin, despite treatment with prednisone.

Two lysosomal glycohydrolases, beta-galactosidase and beta-N-hexosaminidase which have been associated with kidney disease were measured in the urine of 110 youngsters with juvenile diabetes mellitus. The mean enzyme excretions in the diabetic group were intermediate between those of normal youngsters and those with active renal disease. Three youngsters with known kidney disease had elevations comparable to others in the diabetic group but no direct correlation could be shown between enzyme elevations and proteinuria or Addis count abnormalities. Positive correlations were seen between enzyme levels and indices of metabolic balance including blood sugar, cholesterol and triglycerides but not with urine sugar or ketones. Duration and estimated stage and control of diabetes also correlated with the urinary enzymes. These preliminary studies are consistent with the possibility that the excretion of these enzymes reflects the ongoing renal damage which occurs in most juvenile diabetics.

Spontaneous diabetes mellitus has been documented in a colony of guinea pigs. The contagious nature of the disease has been verified, but the nature of the infectious agent is not known. Animals from the original colony or animals exposed to the colony with normal glucose tolerance tests (GTT) became diabetic, as evidenced by elevated one- and four-hour GTT values, and in most cases have significant glycosuria. The severity of pathologic changes in the pancreatic islets parallel, in general, the severity of the clinical symptoms (glycosuria and abnormal GTT). Those animals with severe glycosuria and elevated FBS as well as one- and four-hour GTT values had the most pronounced degranulation and most prominent cytoplasmic inclusions in islet B cells. The severity of scarring in the islets can be correlated with the duration of the overt diabetic state. The other clinical parameters of note were elevated serum triglycerides, normal serum but elevated aortic cholesterol, and absence of ketonemia or ketonuria. The reproductive capacity of diabetic females was compromised. While the clinical manifestations are mild or variable, the presence of significant islet pathology is reminiscent of human juvenile diabetes mellitus. These findings lend support to the concept that infectious and/or immune mechanisms could be operative in the etiology and pathogenesis of human diabetes mellitus.

The frequency of latent disorders of glucose regulation during pheochromocytoma, is evaluated at 75% of cases. Detailed analysis of 83 cases with a diabetic state, gave the following results: insulin dependent diabetes, 37 cases. Non-insulin dependent, 14 cases. Latent diabetes, 32 cases. The characteristics of the insulin-dependent diabetes were not always suggestive. Insulin dependency was, however, unusual above a certain age. We noted loss of weight in spite of good control of the diabetes, the absence of acidosis and ketosis contrasting with rapid loss of weight. In fact, it is above all the hypertension which should lead to diagnosis. Surgical operation, cures or improves considerably the diabetic state, thus proving the symptomatic nature of this diabetes.

There is considerable evidence that at least some cases of juvenile onset diabetes mellitus in humans are a result of viral infection. Viral-induced diabetes in mice may provide an experimental counterpart more similar to the clinical situation than chemical-induced diabetes. Our experiments in such mice indicate that islet transplantation is effective in ameliorating viral-induced diabetes and is encouraging for ultimate clinical application of islet transplantation to juvenile onset insulin-dependent diabetics. In addition, our results show that islets in ectopic sites outside of the pancreas are resistant to damage induced by primary viral infection. The mechanism of this resistance is obscure and will be the subject of future investigations.
