Acute skin exposure to ultraviolet light triggers neutrophil-mediated kidney inflammation.

Proc Natl Acad Sci U S A 2021 01;118(3)

Division of Rheumatology, University of Washington, Seattle, WA 98195;

Photosensitivity to ultraviolet (UV) light affects up to ∼80% of lupus patients. Sunlight exposure can exacerbate local as well as systemic manifestations of lupus, including nephritis, by mechanisms that are poorly understood. Here, we report that acute skin exposure to UV light triggers a neutrophil-dependent injury response in the kidney characterized by upregulated expression of endothelial adhesion molecules as well as inflammatory and injury markers associated with transient proteinuria.

Acute interstitial nephritis, a potential predictor of response to immune checkpoint inhibitors in renal cell carcinoma.

J Immunother Cancer 2020 10;8(2)

Department of Internal Medicine, University of Texas Southwestern, Dallas, Texas, USA

Immune checkpoint inhibitors (ICIs) such as nivolumab and ipilimumab have improved outcomes in metastatic renal cell carcinoma (mRCC) patients, but they are also associated with immune-related adverse events (irAEs). As observed in melanoma, we hypothesized that patients experiencing an autoimmune reaction directed against the tissue of origin may be more likely to benefit from ICI. Specifically, we asked whether patients with immune-related acute interstitial nephritis (irAIN) exhibited improved outcomes. Read More

Nephrotoxicity in cancer treatment: An overview.

World J Clin Oncol 2020 Apr;11(4):190-204

Instituto Multidisciplinar em Saúde, Universidade Federal da Bahia, Vitória da Conquista 45029094, Bahia, Brazil.

Anticancer drug nephrotoxicity is an important and increasing adverse drug event that limits the efficacy of cancer treatment. The kidney is an important elimination pathway for many antineoplastic drugs and their metabolites, which occurs by glomerular filtration and tubular secretion. Chemotherapeutic agents, both conventional cytotoxic agents and molecularly targeted agents, can affect any segment of the nephron including its microvasculature, leading to many clinical manifestations such as proteinuria, hypertension, electrolyte disturbances, glomerulopathy, acute and chronic interstitial nephritis, acute kidney injury and at times chronic kidney disease.

Tetramethylpyrazine Prevents Contrast-Induced Nephropathy via Modulating Tubular Cell Mitophagy and Suppressing Mitochondrial Fragmentation, CCL2/CCR2-Mediated Inflammation, and Intestinal Injury.

Oxid Med Cell Longev 2019 16;2019:7096912. Epub 2019 May 16.

Center for Radiological Research, Department of Radiation Oncology, College of Physician and Surgeons, Columbia University, 630 West 168th Street, NY 10032, USA.

Contrast-induced nephropathy (CIN) is a leading cause of hospital-acquired acute kidney injury (AKI), but detailed pathogenesis and effectual remedy remain elusive. Here, we tested the hypothesis that contrast media (CM) impaired mitochondrial quality control (MQC) in tubules, including mitochondrial fragmentation and mitophagy, induced systemic inflammation, and intestinal injury. Since we previously demonstrated that the natural antioxidant 2,3,5,6-tetramethylpyrazine (TMP) can be a protectant against CIN, we moreover investigated the involved renoprotective mechanisms of TMP.

MRI of acute appendicitis.

J Magn Reson Imaging 2019 11 18;50(5):1367-1376. Epub 2019 Mar 18.

University of North Carolina Department of Radiology, Division of Abdominal Imaging, Chapel Hill, North Carolina, USA.

Appendicitis is the most common cause of acute abdominal pain resulting in surgery. While historically ultrasound (US) and computed tomography (CT) have been used to evaluate for appendicitis and its related complications, magnetic resonance imaging (MRI) has become a highly accurate and increasingly utilized modality in the last two decades, particularly in the pediatric and pregnant patient populations in whom ionizing radiation is used reluctantly. This article discusses the advantages and disadvantages of MRI as a modality to evaluate for acute appendicitis, summarizes studies of the diagnostic performance relative to CT and US, provides a standard MR protocol, and describes MRI findings typical of acute appendicitis, common complications, and other differential diagnoses.
