Drugs are a frequent cause of acute tubulointerstitial nephritis (ATIN). Antibiotics, non-steroidal anti-inflammatory drugs and recently proton pump inhibitors stand among the most commonly responsible ones. However, their respective responsibility is not well known. This study reports 33 cases of drug-induced ATIN (DI-ATIN), the most frequent ones being metamizole and omeprazole. Clinicians of...

The differential diagnosis of vancomycin associated renal toxicity includes acute tubular necrosis and interstitial nephritis. We report a case of vancomycin induced renal toxicity shown by Tc-99m mercaptoacetyltriglycine renal scan. Nephrotoxicity was evolved secondary to vancomycin used for treating a patient with meningitis. Tc-99m mercaptoacetyltriglycine renal scan may play a role in diffe...

BACKGROUND IgG4-related disease is a multi-organ disorder characterized by a high level of serum IgG4 and dense infiltration of IgG4-positive cells into affected organs. In routine studies, however, IgG subclasses are not estimated. In the present study, we attempted to clarify the light-microscopic characteristics of IgG4-related tubulointerstitial nephritis (TIN) to facilitate distinction fro...

Tubulointerstitial nephritis (TIN) is not commonly associated in aminosalicylate-naïve patients with Crohn's disease (CD). Our case describes the initial presentation, diagnosis, and management of an adolescent presenting with TIN and underlying CD. Our case emphasizes that CD should be considered in the differential diagnosis of interstitial nephritis as not only a medication-related effect, b...

Drug associated acute interstitial nephritis and minimal change disease has been well documented but the simultaneous presentation of both is rare and has not been reported with clarithromycin. We describe a case of simultaneous acute tubulointerstitial nephritis and minimal change disease induced by clarithromycin. The patient had acute kidney injury, nephrotic syndrome, eosinophilic pneumonit...

Drug rash with eosinophilia and systemic symptoms (DRESS syndrome) is a rare and severe drug-induced hypersensitivity syndrome characterized by haematological abnormalities (hypereosinophilia and/or mononucleosis) and multiorgan involvement. Renal failure has been rarely described. We report the case of a 77-year-old female with sulphasalazine-induced DRESS syndrome who improved rapidly on cort...

Thy-1 nephritis was induced in stroke-prone spontaneously hypertensive rats (SHR-SP) with unilateral nephrectomy (UNX) and normotensive same genetic strain Wistar-Kyoto (WKY) rats with UNX to evaluate whether the tubulointerstitial injury in Thy-1 nephritis is accelerated by long-term systemic and intraglomerular hypertension. SHR-SP that underwent UNX at twelve weeks of age were randomly assig...
