Urinary immunoreactive brain natriuretic peptide in patients with renal disease.
    Regulatory peptides, 1996, Jul-05, Volume: 63, Issue:2-3

    Urinary immunoreactive brain natriuretic peptide (BNP) was studied by radioimmunoassay in patients with renal disease. Urinary immunoreactive human BNP excretion measured in 11 normal subjects was 3.82 +/- 0.62 pmol/day (mean +/- SEM). Significantly increased 24-h urinary secretion of immunoreactive human BNP was noted in patients with chronic renal failure (11.07 +/- 1.73 pmol/day, n = 9, P < 0.05 to normal subjects). A significant correlation was noted between 24-h urinary excretion of immunoreactive human BNP and creatinine clearance in patients with various renal diseases (r = -0.43, P < 0.01, n = 45). Gel chromatography of the urine extracts obtained from normal subjects and patients with chronic renal failure showed multiple immunoreactive peaks; two eluting earlier, one in the position of human BNP-32 and others eluting later. Reverse-phase high-performance liquid chromatography of the urine extracts showed a peak in the position of human BNP-32 and a peak eluting earlier. These findings indicate that: (1) immunoreactive human BNP is present in human urine; (2) urinary immunoreactive human BNP consists of multiple components, i.e., human BNP-32 itself or a substance very similar to it, smaller molecular forms which are probably metabolic products of human BNP-32, and larger molecular forms; and (3) 24-h urinary excretion of immunoreactive human BNP is increased in patients with renal dysfunction.
