Implication

Animal study reveals taurine supplementation reduces kidney damage in diabetic rats, highlighting the protective role of targeted antioxidants against renal oxidant injury.

Key Points

To assess the comparative effects of long-term taurine and vitamin E supplementation on renal structure and function in chronic streptozocin-induced diabetic rats.
Male Sprague-Dawley rats with streptozocin-induced diabetes were assigned to four groups followed for 52 weeks: untreated, insulin-treated (6 U Ultralente insulin/day), taurine-supplemented (1% in drinking water), or vitamin E-supplemented (100 IU/kg chow).
Assessed outcomes included survival, glomerular filtration rate, proteinuria, albuminuria, renal histology (hypertrophy, type IV collagen, glomerulosclerosis, tubulointerstitial fibrosis), malondialdehyde levels, serum free Fe2+, and advanced glycooxidation products.
Taurine supplementation reduced total proteinuria and albuminuria by nearly 50%, prevented glomerular hypertrophy, preserved type IV collagen staining, and diminished glomerulosclerosis and tubulointerstitial fibrosis.
Taurine normalized renal cortical malondialdehyde, reduced serum free Fe2+, and decreased advanced glycooxidation products in skin collagen.
Vitamin E supplementation exacerbated diabetic nephropathy, accelerated lipid peroxidation and advanced glycooxidation product accumulation, and resulted in an 84% mortality rate by 6 months.
