Results from this study3

No result from this study comes from a test of the peptide.

Natural levels measured3

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In 39 patients with VIP-producing tumours, plasma VIP concentrations ranged from 29 to 2550 pmol/l.

    Summary · context
    Regional specific antibodies and chromatography were used to analyze the concentration and molecular forms of vasoactive intestinal peptide (VIP) and peptide histidine methionine (PHM) in plasma from 39 patients with VIP-producing tumors.

    This result measures the body's own Vasoactive intestinal peptide (VIP, aviptadil). Nobody was given the peptide. It is not evidence about taking it.

  2. 02HumanEndogenous levelObservational studyOther

    In 39 patients with VIP-producing tumours, plasma C-terminal PHM values correlated closely with VIP concentrations.

    In plain wordsIn 39 patients with VIP-producing tumours, blood PHM measured at one end of the molecule tracked the body's own VIP levels closely.

    Summary
    Plasma VIP concentrations ranged from 29 to 2550 pmol/l and the corresponding PHM immunoreactive values measured with C-terminally directed antibody were 42 to 2100 pmol/l which correlated closely with the VIP concentrations.

    In 39 patients with VIP-producing tumours, N-terminal PHM concentrations were higher than C-terminal values and correlated poorly with VIP concentrations.

    Summary
    N-terminal PHM concentrations were significantly higher than the C-terminal values ranging from 92 to 5850 pmol/l and correlated poorly with the corresponding VIP concentrations.
