A pharmacist's perspective on health and metabolic disease

Sunday edits….

It has been a day of editing. My thesis is ready to go to the binders, and have just completed proofing the new article on the Kraft database.

Here’s the link to the article.   Unfortunately, this one is not Open Access.

It was a great honour to work with Dr Kraft with this article.


Objective: Hyperinsulinaemia is associated with development of chronic metabolic disease and is emerging as a health risk independent to that of insulin resistance.  However, little is known to what extent hyperinsulinaemia occurs with normal glucose tolerance in lean subjects.

Method: Oral glucose tolerance tests with concurrent insulin assay were conducted during the 1970s-1990s.  Participants were classified according to glucose tolerance and insulin response pattern.  Analysis of variance compared differences in plasma glucose, plasma insulin, and demographic and metabolic risk factors between groups.

Results: Participants with normal glucose tolerance comprised 54% (n= 4185) of the total cohort. Of these, just over half (n = 2079) showed hyperinsulinaemia despite normal glucose clearance.  Obesity had a modest association with hyperinsulinaemia in people with normal glucose tolerance.  Fasting insulin had limited value in diagnosing hyperinsulinaemia.  The majority of participants (93%) with impaired glucose tolerance or diabetes had concurrent hyperinsulinaemia.

Conclusion: Hyperinsulinaemia in the absence of impaired glucose tolerance may provide the earliest detection for metabolic disease risk and likely occurs in a substantial proportion of an otherwise healthy population.  Dynamic insulin patterning may produce more meaningful and potentially helpful diagnoses.  Further research is needed to investigate clinically useful hyperinsulinaemia screening tools.
