The IgG4-related disease has a wide clinical spectrum where multiple organs can be affected, and the diagnosis depends on typical histopathological findings and an elevated IgG4 expression in plasma cells in the affected tissue. We describe the clinical presentation and evolution of a patient with acute tubulointerstitial nephritis, severe kidney failure and systemic manifestations such as lymphadenomegaly and chronic pancreatitis. The diagnosis was confirmed by the clinical picture and kidney and lymph node histopathology, in which immunohistochemistry of the lymphoid tissue showed policlonality and increased expression of IgG4, with a IgG4/total IgG ratio > 80%...

Acute tubulointerstitial nephritis (TIN) is a common cause of acute renal impairment, characterized by the infiltration of inflammatory cells in the interstitium of the kidney. We retrospectively reviewed the medical records of 19 acute TIN patients attended to our Pediatric Nephrology department between April 1999 and April 2014. Nineteen patients (7 boys and 12 girls) were evaluated. The median age was 14 years (range 7-19). Five were diagnosed as TIN histopathologically, fourteen patients were diagnosed as clinically...

: Drug-related acute tubulointerstitial nephritis is one of the most common causes of childhood acute renal failures which originate from kidneys. Sixteen-year old male patient with the history of isotretinoin use for the last 3 months was admitted with acute renal failure. Renal function parameters were measured as follows: blood urea nitrogen 21 mg/dL, serum creatinine 1.68 mg/dL, cystatin C 1.15 mg/L, and estimated glomerular filtration rate based on cystatin C 56.5 mL/min/1.73 m2...

Acute lymphoid leukemia is the most frequently occurring malignancy in childhood, but acute tubulointerstitial nephritis with associated acute renal failure as the leading manifestation of leukemia is extremely rare. Only a few pediatric cases have been described in the literature. We present a surprising case in which physical examination and initial investigation were not typical for leukemia. Ultrasound showed only modest kidney enlargement while laboratory results indicated acute renal failure. Renal biopsy indicated tubulointerstitial nephritis, and subsequent steroid treatment led to sudden clinical improvement...

Tubulointerstitial Nephritis with Uveitis (TINU) syndrome is a rarely seen syndrome. The interstitial nephritis may be with the concurrent uveitis and can also develop before or after uveitis. The syndrome can resolve after elimination of the culprit destructive factors, such as drugs, toxins and immune reaction. Synthetic cannabinoids have emerged as drugs of abuse with increasing popularity among young adults. Recent literature has documented reports of acute kidney injury in association with the use of synthetic cannabinoids; however, there is no report of TINU syndrome development secondary to using of synthetic cannabinoids...

A 56-year-old man with a history of diabetes mellitus type-2 and stage-2 chronic kidney disease secondary to diabetic nephropathy presented with an acute deterioration of kidney function. Non-invasive work-up failed to reveal the underlying aetiology for the acute kidney failure. Kidney biopsy revealed acute tubulointerstitial nephritis (ATIN) which was attributed to sitagliptin use. Only few case reports have shown this correlation. Our aim is to alert physicians and other providers of the potential effect of sitagliptin to cause ATIN with this biopsy-proven case...

Immune checkpoint inhibitors (CPIs), monoclonal antibodies that target inhibitory receptors expressed on T cells, represent an emerging class of immunotherapy used in treating solid organ and hematologic malignancies. We describe the clinical and histologic features of 13 patients with CPI-induced acute kidney injury (AKI) who underwent kidney biopsy. Median time from initiation of a CPI to AKI was 91 (range, 21 to 245) days. Pyuria was present in 8 patients, and the median urine protein to creatinine ratio was 0...

Immune-checkpoint inhibitors are emerging as revolutionary drugs for certain malignancies. However, blocking the co-inhibitory signals may lead to immune-related adverse events, mainly in the spectrum of autoimmune diseases including colitis, endocrinopathies and nephritis. Here, we report a case of a 75-year-old man with metastatic malignant melanoma treated with a combination of nivolumab (anti-PD1-antibody) and ipilimumab (anti-CTLA-4 antibody) who developed systemic rash along with severe acute tubulointerstitial nephritis after two doses of combination therapy...

We report the findings of a 46-year-old man, who presented with fever and renal dysfunction while undergoing treatment for Crohn's disease with infliximab (IFX). Remittent fever and renal dysfunction with urinary casts developed and lasted for 3 weeks without deterioration of Crohn's disease. Renal biopsy revealed acute tubulointerstitial nephritis (ATIN). After the discontinuation of IFX, his fever and renal abnormalities resolved. We herein report the first known case of ATIN associated with IFX.

Dendritic cells (DCs) play a critical role in the regulation of the adaptive immune response and can be separated into 2 major subsets: myeloid (mDC) and plasmacytoid (pDC) DCs. Acute tubulointerstitial nephritis (ATIN) is a common cause of injury to renal tubules and interstitium resulting from the interplay of tubular cells and inflammatory cells and their products. However, the involvement of DCs in ATIN is still unknown. In this study, the participation and localization of myeloid (CD1c) and plasmacytoid (CD303) DC subsets in the biopsies from patients with ATIN (n=20), lupus nephritis (n=17, positive control), or minimal change disease (n=14, negative control) were investigated...

INTRODUCTION: The metabolic syndrome (MS) encompasses many metabolic abnormalities and the insulin resistance is considered as one of the most significant denominators. The chronic kidney disease (CKD) is an emerging health problem but only few patients would reach the end stage renal disease. There exists an increasing strong association between MS and CKD, but up until now the link between MS and CKD is unclear and there are few studies regarding the renal histology in MS. METHODS: We describe an acute tubulointerstitial nephritis case, due to both infective and pharmacological aetiology, overlapping relevant histological changes (focal segmental glomerulosclerosis [FSG], hyaline arteriosclerosis) in a patient with MS and previously normal renal function...

BACKGROUND/AIMS: The potential physiologic roles of Klotho in acute kidney injury (AKI) have recently been demonstrated in animal models. However, to date, there have been no human studies investigating the expression of renal Klotho in AKI. METHODS: We retrospectively collected biopsy specimens and clinical data of AKI patients between January 2001 and December 2012. Klotho expression was determined by immunohistochemical staining, and the clinical-pathological correlation was examined...
