Tubulointerstitial nephritis (TIN) presents histopathologically as tubulitis and oedema/inflammation and fibrosis, affecting the renal tubules and interstitium with relative sparing of the glomeruli and vasculature. It can be acute or chronic or acute on chronic and has a wide range of etiologies. In this article, we report a case of a 44-year male who presented with acute TIN, associated with the use of diclofenac at therapeutic doses, that resolved with treatment but later progressed to chronic TIN after the patient resumed diclofenac therapy. The case is discussed in the context of literature regarding the nephrotoxic effects of nonsteroidal anti-inflammatory drugs (NSAIDs). Key Words: Nonsteroidal anti-inflammatory drugs, Acute kidney injury, Tubulointerstitial nephritis.

This case report is about an 84-year-old female patient with a history of high-grade serous ovarian carcinoma who was diagnosed with a renal pseudotumor. Initial imaging in February 2023 showed signs of a renal cell carcinoma and possible lung metastases. A CT-guided biopsy and histopathological analysis ruled out malignancy and confirmed a benign inflammatory pseudotumor.

Here, we report an unusual presentation of myeloperoxidase (MPO)-specific ANCA with isolated involvement of the tubulointerstitium in the form of peritubular capillaritis as the sole lesion without any involvement of the glomerulus. A 52-year-old woman with no previous comorbidities presented with nonspecific symptoms such as fatigue, dysuria, and nausea for two months.

The case report presents a male patient in his mid-60s with a history of hypertension, benign prostatic hyperplasia and chronic kidney disease (CKD). He presented with gradually increasing serum creatinine levels and hyperglobulinemia, leading to suspicion of multiple myeloma. However, subsequent testing revealed features consistent with systemic lupus erythematosus (SLE) and IgG4-related kidney disease (IgG4-RKD).

The renal tubule and collecting duct express a large number of proteins, all having putative immunoreactive motives. Therefore, all can be the target of pathogenic autoantibodies. However, autoimmune tubulopathies seem to be rare and we hypothesize that they are underdiagnosed.

Background: Although kidney biopsy is definitive for the diagnosis of acute interstitial nephritis (AIN) and acute tubular necrosis (ATN), its invasiveness limits its use. We aimed to identify urine biomarkers for differentiating AIN and ATN and to predict the response of patients with AIN to steroid treatment.
Methods: In this prospective cohort study, biopsy-proven ATN ( = 34) and AIN ( = 55) were included.
