DRUG INDUCED ACUTE TUBULAR NECROSIS – RARE CASE OF NEPHROTIC SYNDROME

Abstract

We presented two cases of nephrotic syndrome (NS) drug-induced with tubular nephrotoxicity, with different evolution in the context of etiologic diseases. First is 5-month-old girl admitted with NS (clinically and biological proven) and acute renal failure after another hospitalization for pneumonia. The girl was treated with ceftriaxone and gentamicin 12 days. Congenital NS suspicion was eliminated by renal biopsy who revealed renal tubular necrosis highlighting recovery phase. The development was favorable in 7 days of peritoneal dialysis. The second case was 16 years old adolescents treated 3 years with carbimazol for Basedow disease. Was presented with nephrotic syndrome not influenced by corticosteroids. Histopathology revealed toxic tubular necrosis, interstitial fibrosis, absence of glomerular injury. Nephrotoxic treatment was stopped, and, after thyroidectomy, edema were reduced, but kidney function continued to depreciate, while nephrotoxic therapy given for 3 years. Conclusions. Renal tubular necrosis clinical and laboratory expressed by nephrotic syndrome, accompanied by renal insufficiency is a rare occurrence in children; gentamicin and carbimazol can be criminalized. The suffering or impairment may be improved by removing the causative drug. Treatment failure was associated with duration of drug aggression and evolution of comorbidities.
