Sarcoidosis with combined kidney damage - kidney stones, granulomatous interstitial nephritis and acute kidney injury

Fungal granulomatous interstitial nephritis presenting as acute kidney injury diagnosed by renal histology including PCR assay

We describe two cases of fungal granulomatous interstitial nephritis (GIN) presenting as acute kidney injury (AKI). Increased serum creatinine was detected in Patient 1 after chemotherapy for pharyngeal cancer and in Patient 2 after steroid pulse therapy for bronchial asthma. Renal histology of both patients revealed GIN. Polymerase chain reaction (PCR)-based detection of fungal DNA sequences f...

Diagnostic utility of kidney biopsy in patients with sarcoidosis and acute kidney injury

BACKGROUND Sarcoidosis is an idiopathic multisystem disease characterized by noncaseating granulomatous inflammation. Renal biopsy is often performed to evaluate the patient with sarcoidosis and acute kidney injury (AKI). Diagnosis rests on the demonstration of noncaseating granulomas and exclusion of other causes of granulomatous inflammation. This paper reports a patient with pulmonary sarcoi...

Role of WNT10A-Expressing Kidney Fibroblasts in Acute Interstitial Nephritis

WNT signaling mediates various physiological and pathological processes. We previously showed that WNT10A is a novel angio/stromagenic factor involved in such processes as tumor growth, wound healing and tissue fibrosis. In this study, we investigated the role of WNT10A in promoting the fibrosis that is central to the pathology of acute interstitial nephritis (AIN). We initially asked whether t...

Acute kidney injury and chronic kidney disease.

Kidney-liver dialogue in acute kidney injury.

HEMOPEXIN IS A MULTIFUNCTIONAL serum glycoprotein that plays important roles in iron homeostasis, antioxidant protection, anti-inflammatory effects, and signal transduction pathways (6, 8). The liver is the main source of the hemopexin synthesis (7), but expression in other tissues including the retina, peripheral nerves, and neurons of the central nervous system has also been reported. Hemopex...
