    • Calcitonin gene-related peptide (CGRP) seems to be involved in hot flushes in women and in castrated men. Therefore, we studied whether the plasma concentrations of CGRP changed during flushes in a group of healthy aging men. Twelve men (49-71 years) with no history of current or former prostate cancer or hormonal treatment reporting greater than= 20 flushes/week were investigated. Blood samples were drawn during and between flushes for analysis of CGRP and also androgen concentrations, that is, testosterone and bioavailable testosterone were analysed. Skin temperature and skin conductance were monitored. Thirty-five flushes were reported by 10 men. The plasma concentrations of CGRP did not increase during flushes. No significant change in skin temperature or conductance was found. CGRP is probably not involved in the mechanisms of flushes in healthy aging men. Therefore, flushes in aging healthy men seem to be different from flushes in men and women deprived of sex steroids where CGRP increases during flushes.

  • Momentary increase in plasma calcitonin gene-related peptide is involved in hot flashes in men treated with castration for carcinoma of the prostate

    • PurposeIn women the vasodilatory neuropeptides calcitonin gene-related peptide and neuropeptide Y seem to be involved in menopausal hot flashes. We assessed whether plasma calcitonin gene-related peptide and neuropeptide Y change during hot flashes in men after castration.Materials and MethodsWe evaluated 10 men 61 to 81 years old who underwent castration due to cancer of the prostate and had frequent hot flashes for changes in plasma calcitonin gene-related peptide and neuropeptide Y during 1 day at the outpatient clinic. At least 5 blood samples were obtained between flashes and 4 were obtained during each flash. The samples were analyzed for calcitonin gene-related peptide and neuropeptide Y using radioimmunoassay technique. Hot flashes were objectively recorded by measuring peripheral skin temperature and skin conductance.ResultsPlasma calcitonin gene-related peptide increased 46% (95% confidence interval 21 to 71) during flashes in the 6 men in whom it was measurable. This change was statistically significant (p = 0.028). The concentration of neuropeptide Y was below the detection limit. Skin conductance and temperature increased significantly during flashes.ConclusionsCalcitonin gene-related peptide is involved in the mechanisms of hot flashes in men who underwent castration due to prostate carcinoma. Thus, there may be a similar mechanism of hot flashes in women and in men deprived of sex steroids.
