Different genetic backgrounds for malnutrition-related diabetes and type 1 (insulin-dependent) diabetes mellitus in south Indians.

HLA-DRB, -DQA and -DQB genes were studied in ten South Indian malnutrition-related diabetic patients, ten Type 1 (insulin-dependent) diabetic patients and 45 control subjects, by TaqI restriction fragment length polymorphism analysis. The DR7,DQw9 haplotype was found to be frequent in patients with malnutrition-related diabetes (p less than 0.01). The DRw17,DQw2 haplotype was overrepresented in the patients with Type 1 diabetes compared to control subjects (p less than 0.05). In vitro amplification of the polymorphic second exon of DQB genes by the polymerase chain reaction technique was performed on DNA from 10 malnutrition-related diabetic patients, 10 Type 1 diabetic patients and 13 control subjects, as they belong to a new population. Hybridization with sequence-specific oligonucleotide probes for DQB1 alleles showed homozygosity of aspartic acid at position 57 in 7 of 10 malnutrition-related diabetic patients compared to 2 of 10 Type 1 diabetic (p less than 0.05) and 15 of 45 control subjects (p less than 0.05). Homozygosity of non-aspartic acid at position 57 was present in 7 of 10 Type 1 diabetic compared to 0 of 10 malnutrition-related diabetic patients (p less than 0.005) and 3 of 45 control subjects (p less than 0.05). This study has confirmed the association of DQB1 57 non-asp in South Indians with Type 1 diabetes. In addition, our data clearly show that the genetic background of malnutrition-related diabetes mellitus is different from that of Type 1 diabetes.

Effect of bed time intermediate acting insulin in NIDDM subjects refractory to a combination of sulphonylureas and biguanides.

The effect of a single dose of intermediate acting (Lente) insulin given subcutaneously at 9.00 P.M. in 22 NIDDM subjects refractory to a combination of Sulphonylureas and Biguanides was analysed. Euglycemia was achieved and maintained during the study period of three months with a mean insulin requirement of 14.22 +/- 5.98 units/day. Plasma FFA, Total cholesterol, triglyceride and VLDL-cholesterol also showed significant reduction. The level of FFA modulates hepatic glucose production, which in turn correlates positively with the fasting blood glucose. The therapeutic modality of bed time Lente Insulin based on physiological principles is an effective way of achieving glycemic control in NIDDM subjects who have become non-responsive to oral hypoglycemic agents.

Subcutaneous insulin pulse therapy.

Subcutaneous Insulin Pulse Therapy (SIPT) consists of administration of small doses of regular insulin hourly or two hourly in the subcutaneous tissue of anterior abdominal wall through a scalp vein needle. Fifteen Non-Insulin Dependent Diabetes Mellitus (NIDDM) subjects, 8 males and 7 females with mean ages 58 +/- 8.7 years and mean duration of diabetes 11.7 +/- 9.1 years and mean BMI 25.2 +/- 5.64 were admitted for elective surgery. Glycemic control was attempted preoperatively with multiple pre-meal doses of Actrapid MC with a single injection of Monotard MC at bed time. The mean fasting plasma glucose in the 15 subjects with this insulin regimen was 321.28 +/- 69.32 mgm% and the insulin requirement per day was 106.87 +/- 35.77 units. The subjects were put on SIPT for 48 to 72 hours. During SIPT the mean fasting plasma glucose dropped to 123.2 +/- 74.11 mgm% and this marked decline in fasting plasma glucose value was statistically significant (P < .05). The insulin requirement during SIPT was 96.42 +/- 31.36 units, similar to the previous regimen (NS). The subjects were switched back to conventional insulin therapy after SIPT during which period the mean fasting plasma glucose was 125.82 +/- 34.50 mgm% and this value was again significantly lower than the pre SIPT fasting plasma glucose value (P < .05). Insulin requirement during conventional insulin therapy after SIPT was reduced to 71 +/- 21.89 units/day. This dose was significantly lower than the insulin dose administered during SIPT (P < .05).(ABSTRACT TRUNCATED AT 250 WORDS)

Keloids and diabetes in a family.

An interesting familial association of keloids with diabetes mellitus in three successive generations is reported. Keloids did not develop if the injection site was changed to the anterior abdominal wall.

The Eluru survey: prevalence of known diabetes in a rural Indian population.

Asian Indian migrants have a strikingly high diabetes prevalence but prevalence in India has been considered to be relatively low. However, there have been few recent studies, especially in rural India. A house-to-house survey was undertaken in a defined area of Eluru, a small town in South India, and in four adjoining villages. A total of 9563 subjects (4729 male, 4834 female) were surveyed, of whom 5699 lived in Eluru and 3864 in the four villages. Enquiry was made for known diabetes in each household. In all, 157 known diabetic subjects (89 male, 68 female) were ascertained. The prevalence of known diabetes was 6.1% in all subjects aged 40 or over and rose to 13.3% in the age group 50-59 years. The overall crude prevalence of known diabetes was 1.6% (1.9% male, 1.4% female). The prevalence in Eluru (1.5%) was similar to that in the four villages (1.9%). The age-adjusted rates for known diabetes in the middle-aged and elderly subjects are unexpectedly high, considering the poor socio-economic circumstances, decreased health awareness and decreased access to medical facilities, and are comparable with those of similar surveys in relatively affluent Delhi, and in Southall, London. The prevalence in rural (as well as urban) India may be much higher than previously realised. Large formal prevalence studies are urgently required.
