Implication

Animal study reveals that low dietary salt exacerbates cyclosporine-induced renal impairment and tubular damage in rats, suggesting involvement of tubuloglomerular feedback mechanisms.

Key Points

To determine whether dietary salt intake alters the severity of renal function impairment and structural kidney damage caused by cyclosporine administration in rats.
Rats fed a low-sodium diet were assigned to three groups: low-salt water plus oral cyclosporine (100 mg/kg every 48 hours for 3 weeks), high-salt 0.15 M saline plus cyclosporine, or low-salt water plus vehicle.
Renal biomarkers, urinary excretion, plasma renin, and cyclosporine concentrations were assessed at baseline, weekly throughout the 3-week treatment, and across a 3-week recovery period.
Both cyclosporine-treated groups experienced weight loss, but the low-salt group showed significantly greater elevations in serum creatinine and blood urea and a larger decline in creatinine clearance.
High-salt intake increased urine volume and sodium excretion during cyclosporine treatment, whereas vehicle-treated rats gained weight and maintained stable renal parameters.
Histopathology demonstrated mild vacuolar degeneration of proximal tubular cells that was more prevalent in the low-salt cyclosporine group, while plasma renin remained unaffected by drug administration.
