Increased plasma corticosteroid-binding globulin in insulin-dependent pubertal diabetics: relationships with other glycoproteins, growth hormone and prolactin.

A selected group of 13 juvenile-onset insulin-dependent diabetics in mid-late puberty (stages 3-4) and under comparable conditions of metabolic control was studied in order to evaluate the plasma levels of corticosteroid-binding globulin (CBG, transcortin: expressed as the binding capacity for cortisol) in relation to the levels of other glycoproteins and to growth hormone (GH) and prolactin (PRL) responsiveness to provocative tests (arginine infusion and TRH injection, respectively). Further evidence was provided that juvenile-onset diabetics show most frequently enhanced plasma CBG binding capacity; statistical significance with p-values less than 0.01 was attained in comparison to 25 age-matched controls. Among other variables examined, only hemoglobin A1c amd alpha 2-macroglobulin were significantly raised in the diabetic group (p less than 0.01 and less than 0.02, respectively). In our patients growth hormone response to arginine infusion was in the normal range, whereas PRL response to TRH was slightly but significantly supranormal in terms of maximum value and maximum increment above baseline value. No correlation was found between CBG binding capacity and other variables examined. We conclude that raised levels of CBG may occur as an additional alteration of the plasma glycoprotein pattern in juvenile-onset insulin-dependent diabetics. Specific regulatory factors conceivably subserve plasma concentrations of different glycoproteins.

[Blood coagulation parameters in insulin-dependent diabetic children at onset of the disease and after 3 months].

Levels of factors II, V, VII, VIII C, VIII R:Ag, VIII vW, IX, X, PT, PTT, TT, TR, antithrombin III and fibrinogen were evaluated in 11 children with insulin-dependent diabetes mellitus (IDDM) at onset of disease and after 3 months and in 15 healthy age-matched controls. At onset of IDDM a significant increase was observed only in mean values of factor VIII C, VIII R:Ag and in VIII vW. After 3 months the levels of factor VIII C returned within the normal range whilst no variations of factor VIII R:Ag and vW were found. These data show that coagulation abnormalities are already present at onset of IDDM and that endothelial damage evidenced by high values of factor VIII R:Ag and vW may persist even in a phase of good metabolic control. Levels of factor VIII C seem to be related to the increased protein glycosylation of IDDM.
