In developing countries diabetics frequently suffer from varying grades of malnutrition. The combined effect of malnutrition and non-insulin dependent diabetes (NIDDM) on the drug metabolising enzyme system has been evaluated using antipyrine as a protodrug. All the patients were under treatment and their plasma glucose values were within normal limits. The AUC of antipyrine was similar in all the groups. Although none of the kinetic parameters was altered in normal diabetics, the clearance of antipyrine was decreased and its half life was prolonged, with an increase in volume of distribution, in undernourished diabetics compared to undernourished controls. The results indicate that diabetes per se may not influence antipyrine kinetics when the blood glucose is well under control, but in the presence of undernutrition, it significantly alters the disposition of the drug.

Anthropometric studies were carried out in three groups of diabetics seen in southern India, namely fibrocalculous pancreatic diabetes (FCPD) (n = 49) (a subtype of malnutrition related diabetes), insulin dependent diabetes mellitus (IDDM) (n = 55) and non-insulin dependent diabetes mellitus (NIDDM) (n = 104). Both FCPD and IDDM had significantly lower body mass index, skinfold thickness (triceps, biceps, subscapular and suprailiac), mid-arm circumference and fat mass compared to controls and NIDDM patients, (p less than 0.001 for all parameters). FCPD and IDDM males did not show any significant differences in any of the anthropometric parameters studied. Among the females, FCPD had lower triceps skinfold measurements (p = 0.007) and mid-arm circumferences (p less than 0.05) compared to IDDM patients. Patients with NIDDM did not show any significant difference compared to the control group. This study shows that both FCPD and IDDM patients have lower body mass and fat mass compared to NIDDM patients and control subjects.

The prevalence, age at diagnosis, clinical characteristics and treatment of young diabetics, younger than 40 years were determined on the basis of a cross-sectional study of medical records of 2 health districts in Pahang, Malaysia. There were only 20 insulin-dependent diabetics (IDDM), prevalence 0.07 per 1000 inhabitants. There were 84 non-insulin-dependent diabetics (NIDDM), prevalence 0.3 per 1000 inhabitants. Three of the NIDDM patients could have malnutrition-related diabetes. Many NIDDM patients were asymptomatic which is an important reason why many of them remain undetected in the community. Seventy-four percent of the patients below the age of 30 years at diagnosis had NIDDM, 56% of the patients below the age of 20 years at diagnosis also had NIDDM and 54% of the NIDDM patients had a strong family history of diabetes. Many NIDDM patients were misdiagnosed as IDDM, especially if they were underweight, leading to considerable overuse of insulin. This study confirms that IDDM is rare in Malaysia, as in other Asian countries. Most young diabetics have NIDDM and have a strong family history. This pattern of diabetes in the young is unlike that seen in the West.

1. An insufficient dietary supply of iodine results in the development of a variety of disorders of thyroid function and development of the fetus and young infants, grouped under the general heading of Iodine Deficiency Disorders, IDD. Endemic goiter constitutes the most spectacular disorder from the clinical and epidemiological point of view. However, the most serious consequence of iodine deficiency is the impact on neuro-intellectual development at a population level, varying from endemic mental retardation to the complete picture of endemic cretinism. 2. Considering that mental retardation due to iodine deficiency represents the longterm consequence of hypothyroidism occurring during the perinatal period, it is presently recognized that the target groups to the effects of iodine deficiency at a population level are, by order of priority, the fetus, the newborn, the pregnant woman, the child and, finally, the adult. 3. The newborn is more susceptible than the adult to the effects of iodine deficiency. Consequently, systematic screening for congenital hypothyroidism in endemic areas is a particularly sensitive index for detecting the presence and action of goitrogens in the environment and for monitoring the effects of programs of iodine prophylaxis. 4. IDD are particularly prevalent in developing countries. However, large areas or even countries in Europe are still obviously iodine deficient. For example, the iodine intake in adults in Belgium is 50 to 70 micrograms/day which is lower than the recommended dietary allowance for iodine (at least 100 micrograms/day). 5. IDD should be corrected on a world scale, including in Europe. Special attention should be devoted to the protection of mother and child. Within this framework, the iodine content of formula milk should be increased in Europe. 6. Finally, correction of iodine deficiency in Europe would decrease the avidity of the thyroid for iodide and, consequently, would constitute the most efficient preventive measure in case of nuclear fallout.

Fifty-eight insulin-dependent diabetic (IDDM) patients with a disease duration of more than three years were evaluated and divided in three groups depending on the mean sugar blood levels in a three month follow-up. In the first group sugar blood level was lower than 7.7 mmol/l, in the second group it was between 7.7 and 11.1 mmol/l, and in the third group it was higher than 11.1 mmol/l. The nutritional status was evaluated. Protein malnutrition was found in 50% of the evaluated subjects, with a significant relation between the degree of metabolic control and the prevalence of protein malnutrition. In group I (sugar blood level less than 7.7 mmol/l) the prevalence of malnutrition was 31%, whereas in groups II and III (greater than 7.7 mmol/l) it was 54% and 61%, respectively. We discuss the importance to evaluate the nutritional status in diabetic patients, as protein malnutrition is a significant cause of general morbidity and mortality, which can be added to those attributable to diabetes itself.

Cases of malnutrition-related diabetes mellitus conforming to the description of the protein deficient pancreatic diabetes type in Ethiopian patients were compared with Type 1 (insulin-dependent) and Type 2 (non-insulin-dependent) diabetic. Fourteen of 39 malnutrition-related diabetes mellitus patients had fat malabsorption compared with only two of ten Type 1 diabetic patients and one of nine control subjects. Xylose absorption was normal favouring a pancreatic cause for the malabsorption. Plasma C-peptide during oral glucose tolerance test was significantly lower than that in Type 2 diabetic patients and normal control subjects (p less than 0.01 to 0.001) and was also consistently but not significantly higher than in Type 1 diabetic patients. Glucagon secretion patterns were similar in malnutrition-related and Type 1 diabetic patients. Of 23 new malnutrition-related diabetic patients treated with glibenclamide after nutritional rehabilitation and insulin treatment, only three responded, 14 were unresponsive but remained ketosis free for over eight days while another six developed ketoacidosis or significant ketonuria within two to six days during the trial. Sixteen unselected Type 1 diabetic patients who discontinued their insulin therapy all developed frank ketoacidosis after a mean of 5.5 days. The similarity of the malnutrition-related and Type 1 diabetes mellitus in age of onset, insulin requirement for diabetic control and appearance of ketosis-proneness in some cases, together with the similarity of C-peptide and glucagon secretion patterns suggest that the protein deficient pancreatic diabetes variant of malnutrition-related diabetes mellitus may be Type 1 diabetes mellitus modified by the background of malnutrition rather than an aetiologically separate entity.(ABSTRACT TRUNCATED AT 250 WORDS)

The prevalence and clinical features of diagnosed mellitus secondary to chronic pancreatitis (CP) were assessed from northern (Hokkaido) to southern (Okinawa) Japan by means of a questionnaire to elucidate whether WHO-classified malnutrition-related diabetes mellitus (MRDM) exists in Japan. Of a total 17,500 diabetic patients, only two (0.011%)-one fibrocalculous pancreatic diabetes (FCPD) and one protein-deficient pancreatic diabetes (PDPD) - exhibited MRDM characteristics. A total of 649 CP were collected and classified into 268 cases with chronic alcoholic pancreatitis (CAP), 150 cases with chronic calcified pancreatitis (CCP) and 231 cases with other CP. The prevalence of diabetes mellitus was found to be 50.7% in CAP, 72.7% in CCP and 22.8% in other CP. Among all diabetics, 56.6% was noninsulin-dependent (NIDDM) and 26.4% insulin-dependent (IDDM). IDDM was most frequent in CP. Satisfactory and less than satisfactory glycemic control was obtained in approximately three quarters of all subjects. Only one quarter showed poor glycemic control. Insulin treatment was frequent in CAP (52.2%) and CCP (61.7%), but less in other CP (27.5%). The prevalence of diabetic retinopathy was observed in 33.1% of all subjects, nephropathy 21.0% and neuropathy 36.3%, respectively. The prevalence of complications, including macroangiopathy tended to be higher in CAP and CCP (40.3 and 56.9%) than in other CP (31.4%).

Plasma lipid profiles--total cholesterol (TC), LDL-cholesterol, HDL-cholesterol, triglycerides and phospholipids--were studied in relation to two parameters of diabetic control (fasting blood sugar (FBS) for short-term control and glycosylated haemoglobin (HBA1C) for long-term control) in 46 diabetic patients (22 insulin-dependent (IDDM) and 24 non-insulin dependent (NIDDM] and 22 non-diabetic control subjects. We confirmed the positive correlation between FBS and HBA1C. All diabetic patients had significantly higher triglyceride levels (P less than 0.05) than controls, which were not influenced by degree of glycaemic control. NIDDM patients tended to have higher than normal TC levels (P less than 0.05). In IDDM, TC level was positively correlated with HBA1C (r = 0.37, P less than 0.05), and negative correlations were established between FBS and HDL-cholesterol (r = -0.46, P less than 0.02) and the HDL-cholesterol:TC ratio (r = -0.49, P less than 0.01), suggesting an increased atherogenic risk with poorer diabetic control. It is concluded that lipoprotein abnormalities exist in Nigerian diabetics, though not as consistently as in Caucasians. The differences may be due to, among other factors, differences in genetic make-up, diet (typical African diet being rich in plant fibre and poor in cholesterogenic nutrients) and aetiology of the diabetic state (tropical diabetes being highly heterogeneous and now thought to be linked to malnutrition).

Diabetes mellitus is a state of absolute or relative insulin deficiency leading to hyperglycemia and profound changes in the body lipids and proteins. The World Health Organisation (WHO) classification of diabetes distinguishes between: insulin dependent diabetes mellitus (IDDM), non-insulin dependent diabetes mellitus (NIDDM) and malnutrition related diabetes mellitus (MRDM). In childhood the overwhelming majority is due to an autoimmune betacell disease leading to IDDM.

The prevalence of DM is about 0.4/1000 children with a lower incidence in the rural areas. Children comprise 3-5% of the total diabetics. A study of 55 pediatric cases of DM (1980-84) showed that only 22 (40%) had ketoacidosis on admission. Ten (18.2%) had onset of illness before 4 years of age. HLA antigen studies in childhood IDDM have shown a positive linkage disequilibrium with Bw21 (RR-12.7), and DR3 (RR = 16.6). Prevalence of islet cell antibodies (ICA) was 30.9% (n = 110) as compared with 0.8% in controls. Antibodies against Coxsackie B2 virus were increased (75.5% vs 46.4% in controls). The C-peptide content was substantially low. Malnutrition related DM occurs in adolescents in some parts of India. It is characterized by moderate hyperglycemia, low serum glycerol, relative insulin insensitivity, and pancreatic malformation/calcification in about 1/4 of subjects. There is no association with HLA antigens or ICA, and the precise etiology is unclear. Mortality was 3.6% in patients admitted in our hospital but is higher in other regions due to poverty and relative lack of health care facilities.
