Inverse relationship between serum Lp(a) levels and first-phase insulin secretion
M Sidhu, D Crook, IF Godsland, C Walton, V Wynn and MF Oliver
Relationships between serum Lp(a) levels and insulin metabolism were investigated in 147 healthy nonobese men attending an executive health-screening program. Each subject received an IVGTT with measurement of plasma levels of glucose, insulin, and C-peptide. An inverse relationship was seen with the first-phase plasma insulin response when subjects were stratified into quartile ranges of the serum Lp(a) distribution. This relationship was supported by mathematical modeling analyses of these data, which revealed an inverse relationship between serum Lp(a) levels and first-phase pancreatic insulin secretion and plasma insulin responsiveness to glucose.
