Abstract:
:Indomethacin has been used to lower proteinuria in human glomerular diseases with controversial results. The mechanism of indomethacin beneficial effects has not been established. A possible explanation is that indomethacin reduces proteinuria by inhibiting the synthesis of renal prostaglandins (PGs); however, appropriate studies to address this issue have never been done. The objectives of the present study were: to investigate whether indomethacin influences protein excretion in an experimental model of immunologically-mediated glomerular disease; to establish if the possible favorable effect of indomethacin on proteinuria is related to a reduction in glomerular filtration rate (GFR); to establish the possible association between the antiproteinuric effect of indomethacin and its inhibitory effect on arachidonic acid (AA) metabolites of renal or extrarenal origin; and to further investigate the relationship between proteinuria and renal thromboxane (Tx) synthesis previously demonstrated in experimental models of nephrotoxic nephritis and adriamycin (ADR) nephrosis. To this purpose we used an experimental immune-complex disease, passive Heymann nephritis (PHN) which was induced in the rat by a single intravenous (i.v.) injection of heterologous serum directed against a brush border component (gp 330 antigen). Indomethacin at a dose of 6 mg/kg intraperitoneally (i.p.) administered for four consecutive days to PHN animals during the period of heavy proteinuria, effectively reduced urinary protein excretion. The reduction in proteinuria does not appear to be a consequence of a reduction in GFR as documented by inulin clearance. Glomerular synthesis and urinary excretion of vasodilatory prostacyclin (PGI2) and PGE2 were decreased or unchanged in PHN animals in respect to control animals.(ABSTRACT TRUNCATED AT 250 WORDS)
