Oral antidiabetic agents can be used to lower blood glucose levels in some adult-onset diabetics who do not have acute complications and in whom control of hyperglycemia by weight reduction alone or insulin treatment is not possible. Except for their investigational use, these agents have no place in the treatment of chemical or latent diabetes, or subclinical or suspected diabetes, and they are contraindicated in patients with diabetic ketoacidosis. Findings from the University Group Diabetes Progcted and judicious use of these drugs.

The cases of three patients who developed diabetes mellitus (DM) within 2-3 weeks of acute hepatitis A virus (HAV) infection associated with diabetic ketoacidosis are reported. The ketoacidosis was considered an index of insulin dependent diabetes mellitus most likely precipitated by the acute virus infection.

Twelve of 29 Saudi patients (41.4%) developed diabetes mellitus following renal transplantation. Post-transplant diabetes mellitus occurred within the first 2 months in eight patients; two others presented with diabetic ketoacidosis associated with severe infections. The diabetic and non-diabetic patients had received similar doses of prednisolone and cyclosporin (CsA) during the initial 2 months post-transplantation, and their mean CsA blood values at 3 months were not significantly different. Increasing patient age (over 40 years), but not sex, donor source, or body mass index, was associated with an increased risk for developing diabetes mellitus. Post-transplant diabetes mellitus was controlled with oral hypoglycaemic agents in most patients, but one-third required insulin. Patients who developed diabetes had significantly decreased mean creatinine clearance/1.73 m2 at a mean graft age of 3.4 years (P less than 0.001). Diabetes mellitus after transplantation may be more common among Saudi patients than elsewhere, especially those aged over 40 years. It develops rapidly, may present with ketosis, and is associated with graft dysfunction.

Localized proton magnetic resonance (MR) spectroscopy was used to define biochemical changes in gray and white matter of the cerebral cortex in 22 patients with diabetes mellitus (DM), including 10 episodes of diabetic ketoacidosis (DKA), compared with MR spectra in 30 healthy subjects. Five distinct metabolic abnormalities were identified: Concentrations of glucose (Glc) (P greater than or equal to .002), ketone body or bodies, myo-inositol (P greater than or equal to .003) (with or without glycine), and choline (Cho) metabolites were increased in both white and gray matter, whereas a significant reduction of N-acetyl metabolites was found in the parietal cortex (P greater than or equal to .003). Diurnal variations in the intracerebral concentration of Glc were demonstrated in a patient with DM whose condition was stable. Elevated concentrations of ketones were detected in three episodes and excess Cho in two episodes of DKA. Evidence obtained with hydrogen-1 MR spectroscopy favors acetone rather than acetoacetate as the ketone present in the brain, which is a major target of biochemical change in DM.

The occurrence of rhabdomyolysis and acute renal failure associated with cytomegaloviral infection is rare. A 27-year-old housewife was admitted to our hospital with complaints of thirst, muscle weakness, abdominal pain and oliguria. There was no past history of diabetes, drinking, fever or drug habituation and a negative family history. Laboratory tests revealed myoglobinuria, hyper-pancreatic type amylaseuria, hyperglycemia, azotemia and highly increased creatine phosphokinase in the plasma. She was treated with hemodialysis and insulin therapy. Serological studies showed a 4-fold increase in cytomegalovirus antibody titers 4 weeks after admission. Muscle biopsy specimens showed hyaline degeneration and infiltration of T cell lymphocytes in the muscle. Renal biopsy specimens showed acute tubular necrosis and some myoglobin casts. No cytomegalovirus antigen was found in renal specimens by immunofluorescence study. From these results, it was determined that a systemic cytomegalovirus infection triggered pancreatitis which caused diabetic ketoacidosis, rhabdomyolysis and acute renal failure.

In this article we have focused on the evolving pattern of nutritional management of the person with diabetes. Before the advent of insulin in 1922, it was sufficient to identify a meal plan that would keep people alive until they could be rescued from mortality due to diabetic ketoacidosis (the major killer of the era) by pharmacologic means. Now, the life expectancy of people with diabetes is close to that of the general population and focus has turned to combating the new threats of macrovascular disease and kidney failure. Over recent years the susceptibility of NIDDM patients to macrovascular events has been established and the twofold increase in risk of a heart attack in diabetic men is outshadowed by the four- to fivefold risk in diabetic women and the 13- to 17-fold greater risk in diabetics under the age of 30 years compared with their nondiabetic counterparts. The mechanism behind the susceptibility to macrovascular disease has generated a veritable plethora of investigations focusing on the atherogenic profile of diabetic dyslipidemia. Hyperinsulinemia, insulin resistance, and overtreatment of the diabetic with insulin have been claimed as contributors to the development of premature atherosclerosis. The hallmark of the diabetic dyslipidemia is the tendency to elevated VLDL triglyceride levels and the closely linked reduction in HDL cholesterol. Although there is some controversy on the relationship between triglyceride levels and the incidence of CAD, there is no doubt that HDL is an independent risk factor. It can now be safely said that elevated triglycerides are a risk factor in women and that in men elevated triglycerides constitute a risk factor if accompanied by a reduced HDL level. For these reasons, any approach to nutritional management of the diabetic must attempt not only to normalize glycemia but to make every effort to reduce the atherogenic profile. In the accompanying algorithm (Fig. 4), we consider the risk factors conducive to a reduction in life expectancy and offer a meal plan that is appropriate for the individual with diabetes. For the 80% of NIDDM patients who are obese, a diet with a reduction of 500 to 1000 kcal is in order and this may be achieved by a periodic VLCD. We examined carefully the controversy related to yo-yo dieting and support the notion that its effects in humans are not all that harmful. Ingestion of simple sugars in the high carbohydrate diet has negative effects both on carbohydrate and lipid metabolism.(ABSTRACT TRUNCATED AT 400 WORDS)

We report on a 5-year-old child who survived an intracerebral crisis, following ketoacidosis-revealing diabetes (DKA), with visual impairment due to a vascular occipital lesion. Two and 4 months after the initial episode, a unique hypothalamopituitary disorder consisting in GH, ACTH, TSH deficiencies and central precocious puberty, was detected. Cranial magnetic resonance images showed no visible lesion in the hypothalamopituitary region. The most likely hypothesis is the ischemia of hypothalamopituitary and occipital regions following possible cerebral edema after hyperhydration. She survived with low visual acuteness and received a combined replacement therapy for the neuroendocrinological deficiencies. This case emphasizes that the rehydration at the initial period of DKA is critical, especially when risk factors for cerebral edema are present (young age, marked hyponatremia). The neuroendocrinological consequences of acute cerebral edema are rare, but physicians must be attentive in survivors of these accidents.

Diabetic ketoacidosis (DKA) is a form of decompensated diabetes. When it occurs during pregnancy, it may lead to maternal and fetal morbidity and mortality. DKA is defined by accelerated gluconeogenesis and ketogenesis and occurs most often in the presence of one of four predisposing factors: insulin deficiency (absolute or relative); excess counter regulatory hormones; fasting; and dehydration. Infection is a common catalyst. Once the disorder is diagnosed, intensive obstetrical nursing care is required. The principles of management include rehydration, insulin therapy, electrolyte replacement, and identification and treatment of the underlying cause. A plan for assessment of the pregnant patient with diabetes and in DKA and treatment guidelines are presented.

The epidemiology of diabetes mellitus in Thai children aged 0-15 years was studied in 1985 and compared with a previous study done in 1984. Four hundred and seventy-six questionnaires were sent each year to hospitals in Thailand. In 1984, thirty-six cases of newly diagnosed diabetes mellitus were found of which 35 were IDDM and one was NIDDM. In 1985, twenty-seven cases of new IDDM were found, no case of NIDDM was reported. Two cases of MRD were reported from the Northeastern and Southern part of Thailand. The incidence of IDDM in the whole kingdom of Thailand was 0.19/100,000/year in 1984 and 0.14/100,000/year in 1985. The male to female ratio was 1:1.5 in 1984 and 1:2 in 1985. The peak age at diagnosis showed the main peak at 14 years old in boys. The peak age of girls preceded boys by 1-2 years in 1984 and 1985. Similar findings in 1984 and 1985 were the onset of symptoms showing a seasonal variation with highest frequency in winter with a slight change of increased incidence in the rainy season of 1985. There was an increased incidence of IDDM in families with lower educational and socioeconomic levels. The newly diagnosed IDDM with DKA was 16.2, and 19.5 per cent in 1984 and 1985. The incidence of IDDM in Thai children, aged 0-15 years seems to be the lowest compared to other countries previously described which might be due to some genetic and environmental including diet, micronutrient, eating habits and life-style which might play a role in the difference.

Abnormal amino acid metabolism is sometimes observed among patients with diabetes mellitus. Of many amino acids, alanine and branched-chain amino acids such as valine, leucine, isoleucine show characteristic changes. In diabetic ketoacidosis, plasma concentration of alanine decreases and that of branched-amino acid increases and the oxidation of branched-amino acids is enhanced. Splanchnic amino acid uptake is generally higher in diabetics and this level is partially restored by exercise. Some glycosylated proteins are used to estimate the condition of diabetes mellitus. Increment of urinary glycosylated amino acid excretion is reported in diabetics. Plasma homocysteine, reactive vascular-injuring amino acid, increases in diabetics with nephropathy. Those abnormal amino acid metabolism would be restored after good glycemic control is obtained.
