Studies were performed on 10 Cape coloured non-obese NIDDY (non-insulin-dependent diabetes in the young) patients and 6 controls of similar age, sex and weight. Fasting plasma glucose, glucose assimilation rate, insulin secretion in response to an intravenous glucose tolerance test and percentage binding of radiolabelled 125I-insulin to red blood cells were assessed in all patients before and after one month of glibenclamide treatment. Both insulin secretion (P less than 0.01) and erythrocyte insulin receptor binding (P less than 0.01) were significantly reduced when compared to controls. Although glibenclamide markedly improved the second phase of insulin secretion, the intravenous glucose tolerance test stimulated the total insulin secretion to only 40% of control values. The percentage binding of 125I-insulin to red cell receptors improved considerably with therapy, and did not differ significantly from that of control values.

Diabetes mellitus is not a single disease, but rather a syndrome comprised of a variety of diseases characterized by hyperglycaemia. Indeed it has a heterogeneous nature. Maturity Onset Diabetes of the Young or MODY is an unusual, mild type of hyperglycaemia, which develops in young women, (below the age of 25), who do not require insulin. This study describes 10 pregnancies in MODY women, who are compared to a group of patients with insulin-dependent diabetes mellitus (IDDM), a group with gestational diabetes, and a control group of normal, healthy pregnant women. Our group of pregnant MODY patients proved to have an intermediate form of diabetes, more severe than gestational diabetes and yet not as severe as insulin-dependent diabetes mellitus. Mean duration of diabetes was shorter and mean daily insulin requirement (during pregnancy) was lower among MODY patients in comparison to IDDM gestants. Moreover the frequency of maternal complications and Caesarean deliveries in MODY patients were lower than in the IDDM group, but higher when compared to the gestational diabetes group.

The behaviour of insulin binding receptors is rather unelucidated in non-insulin-dependent diabetes mellitus of the young. Authors in continuing their previous work studied the behaviour of insulin binding receptors of erythrocytes and monocytes in 9 MODY patients. They observed that specific insulin binding of circulating blood cells was significantly decreased in all cases as compared to the controls despite of a good state of metabolism (in the case of erythrocytes 4.63 +/- 1.1% vs. 6.03 +/- 1.7%, p less than 0.05, in the case of monocytes 2.3 +/- 1.2% vs. 3.6 +/- 1.4%, p less than 0.05). The lower value of insulin binding resulted from the decrease of receptor concentrations (in the case of erythrocytes 2.36 +/- 0.78 pmol/l vs. 3.81 +/- 1.14 pmol/l, p less than 0.05).

The magnitude of hGH reserve was investigated in young (16-40 years old) diabetic patients. Forty patients were examined with the arginine infusion test, twenty three with a sensitized version of the L-Dopa test. The patients were divided into four groups based on the type of their illness (IDDM or NIDDY) and the clinical stage of IDDM. It was concluded that the hGH reserve of the various diabetic groups differs from the hGH reserve of healthy persons as well as from one another. Taking into consideration the possible causes of these differences, it is suggested that the hGH reserve depends primarily on the metabolic condition of the patients, while the type of diabetes (IDDM or NIDDY) and the insulin therapy used may also be important contributing factors. Achievement of a good metabolic control within the same type of diabetes leads to the normalization of the previously pathologic hGH reserve.

The familial aggregation and degree of adiposity of 108 Indian patients with non-insulin-dependent diabetes in the young was studied. All patients had onset of diabetes under 30 yr and the female to male ratio was 5:1. Obesity as defined was present in 52 patients (48.2%). A positive family history of diabetes was present in 90 patients (83.3%). Two distinct subtypes emerged in the patients with a positive family history; the offspring of conjugal diabetic parents (29%) and maturity onset diabetes of the young (MODY) with 3-generation transmission (13%). In conclusion, the syndrome of NIDDY in Indians comprises at least 3 subtypes: offspring of conjugal diabetic parents, MODY and patients without a family history (sporadic type).

Ultrasonography was performed in three groups of young diabetics in the tropics, namely MODY, IDDM and tropical pancreatic diabetes (TPD). Several morphological abnormalities of the pancreas such as fibrosis and shrinkage of the gland, increased echogenicity and ductal dilatation were found in patients with TPD. It also helped to localize the site of calculi in the pancreas. MODY and IDDM patients did not show any significant changes except a slight reduction in size of the gland. Ultrasonography is a useful tool in differential diagnosis of young diabetics in tropical countries.

Eight diabetics were found among 464 children, mean age 11.2 years, of 311 unselected insulin-treated mothers. By a method of age correction the total diabetes prevalence among the children at the age of 25 years was calculated as 3.4%. Three children were non-insulin dependent and these patients and their mothers may belong to the autosomal dominant type of diabetes, so-called MODY. In two of the other five families the fathers also had insulin-dependent diabetes; in two more cases first or second degree paternal relatives were insulin-dependent diabetics. Thus the prevalence of insulin-dependent diabetes among the children of insulin dependent mothers married to non-diabetics is calculated as 1.5% at the age of 25 years.

Diabetes is a heterogeneous disease, and its pathogenesis and etiology are still largely unknown. Recent studies have brought new knowledge showing that HLA antigens and diabetes mellitus are related. It has been found that the relative risk of juvenile onset diabetes requiring insulin treatment is greater for persons who are HLA-A1, A2, B8, BW15, BW40, CW3, DW3, DW4, DRW3 and DRW4 positive. The relative risk of the disease is additive in persons who have two of the above mentioned HLA-B alleles. Some HLA antigens (HLA-B7, DW2, DRW2, A11) are associated with a significantly lower risk of the disease and probably have a "protective" character. Maturity onset diabetes (MOD) and maturity onset diabetes not requiring insulin treatment (MODY) are not related to the HLA system. This means that MOD is completely distinct from JOD with different symptoms, course and etiopathogenesis.

Maturity-onset diabetes of the young (MODY) is a model for genetic studies of non-insulin-dependent diabetes mellitus. We have identified 15 MODY families in which diabetes is not the result of mutations in the glucokinase gene. This cohort of families will be useful for identifying other diabetes-susceptibility genes. Nine other candidate genes potentially implicated in insulin secretion or insulin action have been tested for linkage with MODY in these families, including glucokinase regulatory protein, hexokinase II, insulin receptor substrate 1, fatty acid-binding protein 2, glucagon-like peptide-1 receptor, apolipoprotein C-II, glycogen synthase, adenosine deaminase (a marker for the MODY gene on chromosome 20), and phosphoenolpyruvate carboxykinase. None of these loci showed evidence for linkage with MODY, implying that mutations in these genes do not make a major genetic contribution to the development of MODY. In addition to these linkage analyses, one or two affected subjects from each family were screened for the presence of the A to G mutation at nucleotide 3,243 of the mitochondrial tRNA(Leu(UUR)) gene. This mutation was not found in any of these subjects. Finally, we report the localization of the gene encoding the regulatory protein of glucokinase to chromosome 2, band p22.3 and the identification of a restriction fragment length polymorphism at this locus.

Non-insulin-dependent diabetes mellitus (NIDDM) is a clinically and genetically heterogeneous disorder. Maturity-onset diabetes of the young (MODY), an autosomal dominant form of NIDDM, has been used as a model for genetic studies of NIDDM. We recently reported linkage between markers on chromosome 12q and diabetes in 25% of our French MODY families. To evaluate if this gene is also implicated in late-onset NIDDM, we performed linkage studies between two markers of the MODY region and diabetes in 172 families with late-onset NIDDM. Both parametric and nonparametric methods were used in a total of 600 affected sib-pairs. Linkage was rejected in this population by all methods, implying that the MODY gene on chromosome 12q is not a major gene for late-onset NIDDM in this population. However, we cannot exclude a modifying role in a polygenic disorder or an important role in some families.
