BACKGROUND AND OBJECTIVES Tubulointerstitial nephritis and uveitis (TINU) syndrome is considered a rare cause of acute tubulointerstitial nephritis (ATIN) that is usually associated with renal recovery. This study sought to investigate the diagnosis, prognosis, and contributing factors of TINU syndrome using a large cohort of patients with prospective follow-up. DESIGN, SETTING, PARTICIPANTS,...

The patient was a 70-year-old man diagnosed with chronic lymphocytic leukemia (CLL), stage II. The patient was not currently receiving treatment, as the disease state was stable. However, he was later hospitalized for serum creatinine elevation, with a change from 1.5 mg/dL to 3.5 mg/dL within three months. On abdominal CT scans, the kidneys were normal in size. A needle biopsy of the kidney sh...

Chicken pox is mostly a benign infection of childhood and caused by Varicella Zoster Virus which generally does not lead to any serious complication in an immunocompetent host. Severe potentially lethal complications like varicella pneumonia, encephalitis acute kidney injury are known entity adults but very rare paediatric age group. We present case Acute Kidney Injury (AKI) the form tubulointe...

Primary biliary cirrhosis (PBC) is an immunemediated chronic cholestatic liver disease. The etiology is unknown, although it is presumed to be autoimmune in natural (1). PBC is most frequently a disease of women and occurs between the fourth and sixth decades of life. The symptoms may strongly affect patients’ quality of life and may induce incapacitation (2). The major pathology of this diseas...

Leptospirosis is frequently associated with acute kidney injury. Some survivors are known to progress to chronic kidney disease due to sustained tubulointerstitial inflammation. We present a case of severe leptospirosis with acute renal failure. Although antibiotic therapy resolved the infection, moderate renal dysfunction remained. A renal biopsy demonstrated marked inflammatory infiltration i...

BACKGROUND AND OBJECTIVES The therapy and outcome of HIV infection have dramatically changed over the last 15 years, resulting in a change in renal complications. This study analyzed the characteristics of HIV-infected patients and biopsy-proven tubulointerstitial nephropathies to define disease patterns and therapeutic implications. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A clinico-pat...

IgG4-related systemic disease is an autoimmune disease that was first recognized in the pancreas but also affects other organs. This disease may manifest as tubulointerstitial nephritis (IgG4-TIN), but its clinicopathologic features in the kidney are not well described. Of the 35 patients with IgG4-TIN whose renal tissue specimens we examined, 27 (77%) had acute or progressive chronic renal fai...

Sir, Tubulointerstitial diseases including tubulointerstitial nephritis (TIN) have an impact on overall renal function and eventual prognosis of renal diseases [1]. However, the detailed pathogenesis of human TIN has not been fully studied. Renal involvement in anti-neutrophil cytoplasmic antibody (ANCA)-associated diseases shows mainly glomerular lesion, especially necrotizing crescentic glome...

Most patients with SLE develop kidney disease related to this systemic underlying disease process. Lupus nephritis is an important cause of morbidity and even mortality in patients with systemic lupus erythematosus. Lupus nephritis has diverse morphologic manifestations with varying clinical presentations and consequences. The pathogeneses involve immune complexes, which can deposit anywhere in...
