  • ARG plus GHRH test, high sensitivity (96 and 95%, respectively) and specificity (92 and 91%, respectively) for GH deficiency were achieved
  • The greatest diagnostic accuracy occurred with the ITT and the ARG plus GHRH test
  • 95% specificity could be achieved with the ARG plus L-DOPA and ARG tests only with very low peak GH cut-points (0.25 and 0.21 microg/liter, respectively) and not at all with the L-DOPA test
  • ...1 more annotation...
  • Although serum IGF-I levels provided less diagnostic discrimination than all five GH stimulation tests, a value below 77.2 microg/liter was 95% specific for GH deficiency

    study evaluated 6 tests for HGH deficiency diagnosis.  Ninety-five percent specificity found with ARG + l-DOPA and ARG alone.  However, the authors found a 95% specificity with IGF-1 < 77.  Although, IGF-1 is false negative in up to 65% of those with HGH deficiency.

    good article discussing the positive impact of IGF-1 on atherosclerosis.  This hormone, under the control of HGH, is important in the healing and regenerative process.  Thus, the use of the term "anti-aging".  However, these two hormones simply help the body heal, repair, and regenerate itself.  Not surprising, inflammation (TNF-alpha) counteracts these positive effects.

    testosterone and Estradiol effect IGF-1 levels.  This small study looked at 8 men and 8 postmenopausal women.  Findings:  low testosterone and high estradiol decrease IGF-1 availability.   Estradiol in postmenopausal women will result in a decrease in IGF-1 through an elevation of IGFBP-1.  In men, testosterone replacement stimulates increased HGH secretion and resultant IGF-1 secretion

    Testosterone given to elderly men with low "serum" testosterone shown to increase IGF-1 and increased muscle growth and strength.  So, this study shows that testosterone in men, seems to increase HGH production and thus increase IGF-1 production.  This may be the mechanism by which testosterone promotes muscle growth and increase in strength in men.

    Birth control pills were found to reduce IGF-1 levels in the short term and long term.  Those that had used birth control pills had lower IGF-1 levels compared to those that had never used birth control pills.  This fits with the current knowledge that oral estrogen reduces HGH and IGF-1.  Those were in post-menopausal women, but this is in pre-menopaus women.  This has implications on health, weight, disease...
