Heterogeneity of serum basal C peptide levels amongst Arab patients with diabetes mellitus.

Thirty-four Arab patients with history of diabetes mellitus but without history of ketoacidosis (Group 2), and 16 Arab patients with history of diabetes mellitus and ketoacidosis (Group 1) were studied. They were compared with 15 healthy control subjects and were further broken down according to sex and type of therapy. Fasting serum C-peptide, glucose and glycosylated haemoglobin levels were measured in all subjects.

Excess body fat distribution and glucose homeostasis in obese Arab women.

The relationship of body fat distribution to glucose intolerance and non-insulin-dependent diabetes mellitus in Arab women was studied in 102 obese non-diabetic and 40 obese women with diabetes. The obese women underwent a glucose tolerance test. Linear regression analysis revealed a significant correlation between the waist/hip ratio and the plasma glucose concentration at 120 min.

A longitudinal study of insulin antibodies and anti-insulin cytotoxicity in type I diabetes mellitus.

Insulin antibodies and T-cell lymphocyte cytotoxic reactivity against insulin and its related peptides were studied longitudinally in 3 groups of patients with type I diabetes mellitus (DM). Group 1 patients were those in whom the diagnosis was made within 1 week of the initiation diagnosis. They were subdivided into those receiving MC porcine (A) or MC bovine (B) insulin.

Comparative evaluation for pollens and mite extract skin tests.

A study of 105 subjects with a history of atopy was conducted. The skin test was used as screening method and the specific IgE as reference test. The results of the mite extract skin test were compared with those of pollens.
