Maternal serum alpha-fetoprotein (AFP) levels were measured from 12 to 24 weeks gestation in 27 singleton pregnancies in women with insulin-dependent diabetes mellitus and 90 controls without diabetes who were matched for gestational age. The geometric mean AFP level among the diabetic pregnancies was 60 per cent of that in the controls, a difference which was statistically significant (P less than 0.01). The difference in AFP level between diabetic patients and controls was most marked in sera taken before 21 weeks gestation.

"Mason-type" diabetics (mild diabetes which is dominantly inherited) are relatively free of retinopathy. Alcohol almost invariably causes facial flushing in these patients when they are given chlorpropamide (chlorpropamide alcohol flush, C.P.A.F.). 291 non-insulin-dependent diabetics were examined to see whether there was a difference in frequency of retinopathy between C.P.A.F. positive and negative cases who were of comparable age and duration of diabetes. Retinopathy was commoner and often severe in CPAF negative patients. Blindness from retinopathy was almost confined to C.P.A.F.-negative cases. Lens opacities, on the other hand, were equally common in both groups. Since C.P.A.F. is an inherited trait, retinopathy in non-insulin-dependent diabetics is to a considerable extent, although not entirely, determined by genetic factors.

HLA-ABC antigens were determined in 89 patients with biopsy-confirmed lichen planus, and the HLA antigen frequencies were compared with those in 1967 controls. The younger patients were predominantly male, the older patients predominantly female. No significant association was found between HLA types and lichen planus in this study. A slightly greater incidence of HLA-A3 and B5 antigens was seen, but this increased frequency was not as pronounced as reported by others. When combined, available data on HLA and lichen planus indicate a slightly, but significantly, increased frequency of HLA-A3. None of the HLA antigens known to be associated with insulin-dependent diabetes are associated with lichen planus.

A rare genetic type (Bf F1) of properdin factor B is found in 22.6% of patients with insulin-dependent diabetes mellitus but in only 1.9% of the general population, yielding a relative risk of 15.0. This indicates that a genetic locus for insulin-dependent diabetes mellitus is very close on chromosome 6 to Bf, and that Bf F1 is a marker for nearly 1 out of 4 insulin-dependent diabetic patients.

To determine whether abnormalities of lipid and aminoacid metabolism observed in diabetes are corrected when plasma-glucose levels are restored to normal, eight insulin-dependent diabetics were treated for 7-14 days with a portable infusion pump which delivers insulin subcutaneously in basal (between-meal) doses with pulse-dose increments before meals. Mean plasma-glucose (206 +/- 24 mg/dl during conventional insulin treatment) fell to 89 +/- 3 mg/dl at day 7 and 84 +/- 2 mg/dl at day 14 of pump treatment; glycosuria was eliminated. Plasma cholesterol, triglycerides, and free fatty acids were elevated during conventional insulin treatment but fell to normal after 7 days of pump treatment. Plasma-levels of branched-chain aminoacids were 50-60% above control levels during conventional treatment but fell to normal after 7 days of pump therapy. Aminoacids were reduced from their high postprandial levels to normal values after insulin-pump treatment. In addition to restoring plasma-glucose to normal, treatment of diabetes with a portable insulin-infusion system results in restoration of normal lipid and aminoacid metabolism. Long-term use of this system may determine whether metabolic changes resulting from insulin lack cause the complications of diabetes.

When diabetes and cardiovascular disease were first classed as possible fibre-deficiency diseases, laboratory and clinical evidence was lacking. Subsequent studies indicated that the gums and viscous types of fibre (e.g., guar and pectin) are more effective than other fibres in slowing carbohydrate absorption and hence in reducing the postprandial rise in blood glucose and serum insulin. This effect has longer term metabolic consequences. In addition, gums and viscous fibres reduce serum cholesterol, possibly by mechanisms other than simply increasing bile-salt loss. If these potential therapeutic effects of fibre are to be exploited, palatable formulations must be developed. The effect of fibre in whole foods should also be determined.

In man and in rat, the diabetic state is associated with diseases of exocrine pancreatic function. In this work, streptozotocin diabetes was shown to lead to a 95% decrease in the amylase to lipase ratio in rats. Diabetes was reversed by either pancreas transplantation or insulin treatment. Transplantation of neonatal pancreases was successful in reversing the diabetic-induced alterations of exocrine pancreatic function. To assess whether insulin acts directly on the exocrine pancreas, or through the enhancement of glucose utilization, animals were fed either a low-fat diet or a high-fat diet during insulin treatment; this latter diet is well known to impair insulin's effect on glucose metabolism. When diabetic rats were fed a low-fat diet, insulin treatment was able to correct the hyperketonemia and to reverse the amylase to lipase ratio to the prediabetes level. In contrast, the insulin treatment failed to restore the amylase to lipase ratio when the diabetic rats were fed the high-fat diet. Despite insulin treatment, the hyperketonemia worsened implying that glucose utilization remained low as would be expected on high-fat diet. The dependence of the insulin effect upon diet composition demonstrates that the rate of glucose metabolism is the primary factor in the regulation of amylase to lipase ratio.

The sera of 160 diabetics who were well controlled by oral hypoglycaemic agents (OHA) for at least three months after diagnosis were tested for pancreatic islet cell antibodies (ICAb) either at diagnosis or within two years after diagnosis. 129 were non-obese at diagnosis and of these ICAb was detected in the sera in 20 (16%). 31 were obese at diagnosis and of these ICAb was detected in the sera in three (10%). All of the 160 diabetics were insulin independent at the time of testing the serum for ICAb. The presence of ICAb was associated with a high probability of becoming insulin dependent, calculated from actuarial statistics. 86% of ICAb positive patients initially controlled on OHA may be expected to be insulin dependent at five years from diagnosis as compared to 18% of ICAb negative patients. Obesity at diagnosis did not significantly affect the probability of becoming insulin dependent. ICAb positive diabetes controlled by OHA can be regarded as a less severe form of insulin-dependent (Type I) diabetes.

The historical development of research on islets transplantation is briefly reviewed followed by a description of a technique using Ficoll gradient separation to obtain islets of Langerhans from the rat pancreas. It was possible to increase the number of islets obtained with this procedure by modifying it in several ways. The islets were then transplanted in an isologue manner into rats with streptocotocin-induced diabetes. The effect of transplantation on glucose metabolism in these rats was evaluated both by determination of the general symptoms typical for diabetes as well as by the performance of such functional tests as IVGTT, GAC and tolbutamide test. The islets could be transplanted into various locations, but it was found that positive results were obtained only if the liver was the site of application and if than 2100 islets were used. Three hours after transplantation normalization of blood sugar levels and serum insulin could be observed; these levels remained stable over 18 months. It was possible to transplant in the same animal several times. This had an effect on the metabolism which was equivalent to the sum of the separate transplants. By means of both light and electron microscope examination the morphological changes which the transplanted islets underwent at the site of transplantation were observed.

Three cases of hyperthyroidism occurring in juvenile patients with diabetes mellitus are presented. The presence of hyperthyroidism should be suspected in patients with diabetes mellitus when goiters develop and when there is unexplained weight loss, tachycardia, tremors, unexplained increases in insulin requirement, or instability of the diabetes with a tendency toward development of ketosis and/or ketoacidosis.
