Epidemiology, Diagnosis, Medical Care and Prognosis of Tubulointerstitial Nephritis: Results of a Multicenter Retrospective Cohort Study
Tubulointerstitial nephritis (TIN), diagnosed on kidney biopsy, represents a common cause of kidney failure. The etiologies are multiple but the diagnosis of the causative disease is sometimes difficult and the treatment is not completely codified. The research focuses on the characterization of TIN on the etiological, clinical, biological, therapeutic and …
