Authors analyzed the case history of 25 young diabetic patients, whose disease has been diagnosed before the age of thirty. The question that has been raised: is it allowed to treat young diabetics with oral drugs? By classifying the patients, they stated followings: In the 1. group they classified 16 verified MODY/NIDDY patients. In the second group they classified 3 young diabetics, whose disease had been evaluated as slowly progressing IDDM (autoimmune form). 3 patients belonged to the 3 group. They had been classified as MODY/NIDDY patients, however an extremely long lasting remission period--due to the short observation time--can not be excluded. The remaining 3 diabetic patients belonged to the IDDM group, with a long remission period. They were treated incorrectly with oral hypoglycemic drugs. Young diabetics can be treated with oral drugs only in case, when they are proven MODY/NIDDY patients. The precise differential diagnosis between this form and autoimmune IDDM, as well as long lasting remission periode, is extremely important.

The authors deal with the clinical picture of total remission in diabetes, among young patients (below 30 years). In their interpretation "complete remission" means total withdrawal of insulin treatment for at least 2 months. Out of 14 patients with complete remission, the classified 7 patients--by clinical and immunogenetical parameters--as noninsulin-dependent diabetes in the young (MODY-NIDDY). 1 diabetic patient belongs to the autoimmune-subgroup of IDDM. The remaining 6 patients could be classified as IDDM-s. However their clinical and immunogenetical parameters were rather atypical. In conclusion they raised the possibility that this subgroup is heterogenous with in IDDM.

We report the clinical records of 45 children with abnormalities regarding glycemic regulation characterized by a non-insulin deficient hyperglycemia (NIDH), known under the different names of chemical diabetes, sub-clinical diabetes and more recently MODY. These 45 children belong to 31 families with 532 relatives comprising 137 cases of NIDH which could have been studied. The symptoms of this biochemical abnormality, the pathophysiology of which is not yet clearly understood, are the following: lack of clinical manifestations, except for a variable and intermittent glycosuria; constant abnormal glucose tolerance tests, above 97 percentiles of the reference value with some variations over time; normal immunoreactive insulin levels; percentage of glycosylated hemoglobin at the upper range of normal; dominant autosomal genetic transmission and no association with HLA markers like in insulin-dependent diabetes; lack of degenerative complications of the micro-angiopathic type, at least on these cases even after more than 30 years of follow-up; finally, no tendency towards insulin-dependent diabetes. The NIDH should not be confused with the slow and progressive beginning of insulin-dependent diabetes for which prolonged delay is needed to affirm the diagnosis. The frequency of the biochemical phenomena is about 1.8% of the cases of authentic diabetes mellitus occurring before the age of 15.

In 12 members of a family with MODY, insulin and C-peptide release after intake of a test breakfast was measured as well as binding of insulin to its erythrocyte receptor. According to serum glucose concentrations, subjects were classified into: diabetic, carbohydrate intolerant, and normal subjects. The two diabetic patients had an insulin release pattern similar to that of non-insulin dependent diabetics. The two patients with carbohydrate intolerance presented hyperinsulinism either at base state and after stimulation. Of the eight normal subjects, three presented high concentrations of serum insulin either at base level and after stimulation; in the remaining five, base insulinemia was normal and the response after food intake was poor. Insulin binding to the receptor was decreased in diabetic patients and this anomaly was more evident in patients with carbohydrate intolerance. In the three patients with increased serum insulin concentration, no disturbances in insulin-receptor binding were detected; in the remaining five patients, insulin-receptor binding was significantly decreased. Our findings prove that these subjects present a disturbance of insulin release and an impairment of insulin-receptor binding with a predominance of one or the other alteration even before hyperglycemia is evident.

Both early onset and late onset type II diabetes were present in one family of nine siblings. The three early onset type II diabetic siblings showed severe microvascular complications: proliferative retinopathy, diabetic nephropathy, and peripheral neuropathy. Early onset type II diabetes was not associated with any particular HLA haplotype. Early onset type II diabetes could be considered a clinical and genetic disease entity different from MODY type diabetes.

Nineteen diabetics aged 9 to 18 years with the MODY type were investigated, incl. their families, by the oGTT. Diabetes in the parents was nine times and in siblings four times more frequent than in families of adolescents with IDDM. In parents the manifest form predominated, in siblings PGT. Vertical transmission of diabetes in three consecutive generations was found only in the MODY type (in 35%). Diabetes with the MODY type and their diabetic siblings did not differ significantly as to their mild glucose intolerance (blood sugar level up to 13 mmol/l), and their mild diabetic phenotypes did not differ either. Similarly diabetics with IDDM and their diabetic siblings did not differ substantially as to their severe glucose intolerance (blood sugar level up to 21 mmol/l), and their severe diabetic phenotypes did not differ either. IRI levels revealed five times a hyperinsulinaemic and three times a normal insulinaemic response. Obese diabetics were treated with a reducing diet and physical activity. To non-obese diabetics, if the above procedure was not sufficiently successful, sulphonylurea preparation were also administered. During check-up examinations fasting values and values three hours after a meal lower than 6.1 mmol/l were required. In the course of a four- to ten-year follow up it did not change. Existence of the MODY type already macroangiopathic complications developed; in one diabetic the glucose tolerance improved, in the remainder it did not change. Existence of the MODY type already in adolescents justifies early detection in families with a cumulated incidence of NIDDM and prophylactic procedures ensuring euglycaemia in confirmed diabetics.

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.

Insulin resistance was assessed by euglycaemic clamp studies in matched groups of MODY, classical NIDDM patients and non-diabetic control subjects. The MODY patients metabolised less glucose (4.8 +/- 0.3 mg/Kg/min) than the classical NIDDM patients (7.0 +/- 0.5 mg/Kg/min) at an insulin infusion rate of 1.0 mU/Kg/min (p less than 0.05). At an insulin infusion rate 10 mU/Kg/min the differences between the MODY and the classical NIDDM patients were not significant. At both infusion rates the two diabetic groups metabolised less glucose than the control subjects. The results indicate that despite their younger age, the patients with MODY are more insulin resistant than the patients with classical NIDDM.

Non-insulin-dependent diabetics with early manifestation of the disease (NIDDM) who were registered by an epidemiological cross-sectional study 1979 in the Erfurt district were pursued prospectively and 47 of the 58 patients underwent a re-examination five years later. The changes of therapy performed (7 new administrations of insulin, 9 change from diet to normal food) as well as the metabolic development of the patients under epidemiological aspect prove the heterogeneity of NIDDM and the doubtfulness of hitherto existing MODY-criteria. The oGTT performed in 37 patients 9 times resulted in a full remission and in 4 cases in an IGT. Including the 10 insulinized patients 34 diabetics (72.3%) had remained manifest. In contrast to the initially different degree of post-load hyperglycaemia in patients with and without remission the behaviour of the insulin secretion did not show any significant differences in the course and between the groups of patients. Young non-insulin-dependent diabetics are mainly among a representative target population type-II-diabetics with early onset. In contrast to this type-I-diabetics with a long insulin-free initial phase go into the background. In our population real MODY-cases are apparently extraordinarily rare.

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).
