BACKGROUND/AIM: Steroidal mineralocorticoid receptor antagonists (MRAs) are
effective in the treatment of kidney disease; however, the side effect of
hyperkalaemia, particularly in the context of renal impairment, is a major
limitation to their clinical use. Recently developed non-steroidal MRAs have
distinct characteristics suggesting that they may be superior to steroidal MRAs.
Therefore, we explored the benefits of a non-steroidal MRA in a model of rapidly
progressive glomerulonephritis. METHODS: Accelerated anti-glomerular basement
membrane (GBM) glomerulonephritis was induced in groups of C57BL/6J mice which
received no treatment, vehicle or a non-steroidal MRA (BR-4628, 5mg/kg/bid) from
day 0 until being killed on day 15 of disease. Mice were examined for renal
injury. RESULTS: Mice with anti-GBM glomerulonephritis which received no
treatment or vehicle developed similar disease with severe albuminuria, impaired
renal function, glomerular tuft damage and crescents in 40% of glomeruli. In
comparison, mice which received BR-4628 displayed similar albuminuria, but had
improved renal function, reduced severity of glomerular tuft lesions and a 50%
reduction in crescents. The protection seen in BR-4628 treated mice was
associated with a marked reduction in glomerular macrophages and T-cells and
reduced kidney gene expression of proinflammatory (CCL2, TNF-?, IFN-?) and
profibrotic molecules (collagen I, fibronectin). In addition, treatment with
BR-4626 did not cause hyperkalaemia or increase urine Na+/K+ excretion (a marker
of tubular dysfunction). CONCLUSIONS: The non-steroidal MRA (BR-4628) provided
substantial suppression of mouse crescentic glomerulonephritis without causing
tubular dysfunction. This finding warrants further investigation of non-steroidal
MRAs as a therapy for inflammatory kidney diseases.
