Insulinogenic indexes in psoriasis.
We have earlier demonstrated that in psoriasis there exists a reduced tolerance to carbohydrates in association with hyperinsulinism. To pursue this problem further, we felt it worthwhile to deal with the results of the oral glucose tolerance test performed on 78 subjects (divided into homogenous groups of normal, obese and psoriatic groups, both with and without diabetic genetic history and obesity) with determinations of both blood glucose and blood insulin levels. We have calculated the insulinogenic indexes by using the techniques elaborated by various authors (I/G, delta I/delta G, AI/AG) and we have then carried out a statistical evaluation both of these indexes and of the ratio between the various indexes employing not only the usual techniques but also that of correlation and simple and multiple regression. We have done this in order to evaluate which of these indexes is better suited to demonstrate the physiopathological mechanism concerning the relationship between insulin hypersecretion and reduced carbohydrate tolerance in the various pathological conditions which we have dealt with.
