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.

Viral opportunistic infections in Mauritian cynomolgus macaques undergoing allogeneic stem cell transplantation mirror human transplant infectious disease complications.

Xenotransplantation 2020 Jan 13:e12578. Epub 2020 Jan 13.

Vaccine and Gene Therapy Institute, Oregon Health & Science University, Beaverton, Oregon.

Allogeneic hematopoietic stem cell transplantation (HSCT) and xenotransplantation are accompanied by viral reactivations and virus-associated complications resulting from immune deficiency. Here, in a Mauritian cynomolgus macaque model of fully MHC-matched allogeneic HSCT, we report reactivations of cynomolgus polyomavirus, lymphocryptovirus, and cytomegalovirus, macaque viruses analogous to HSCT-associated human counterparts BK virus, Epstein-Barr virus, and human cytomegalovirus. Viral replication in recipient macaques resulted in characteristic disease manifestations observed in HSCT patients, such as polyomavirus-associated hemorrhagic cystitis and tubulointerstitial nephritis or lymphocryptovirus-associated post-transplant lymphoproliferative disorder.

Positron emission tomography as an adjuvant diagnostic test in the evaluation of checkpoint inhibitor-associated acute interstitial nephritis.

J Immunother Cancer 2019 12 21;7(1):356. Epub 2019 Dec 21.

Division of Nephrology, Department of Medicine, Harvard Medical School, Massachusetts General Hospital, 165 Cambridge Street Suite 302, Boston, MA, 02114, USA.

Background: Acute interstitial nephritis is an immune-related adverse event that can occur in patients receiving immune checkpoint inhibitor therapy. Differentiating checkpoint inhibitor-associated acute interstitial nephritis from other causes of acute kidney injury in patients with cancer is challenging and can lead to diagnostic delays and/or unwarranted immunosuppression. In this case report, we assess the use of F-flourodeoxyglucose positron-emission tomography imaging as an alternative diagnostic modality in the evaluation of potential acute interstitial nephritis.

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.

DNA Damage and Deficiencies in the Mechanisms of Its Repair: Implications in the Pathogenesis of Systemic Lupus Erythematosus.

J Immunol Res 2018 12;2018:8214379. Epub 2018 Jul 12.

Facultad de Medicina y Ciencias Biomédicas, Universidad Autónoma de Chihuahua, Chihuahua, CHIH, Mexico.

Systemic lupus erythematosus (SLE) is a perplexing and potentially severe disease, the pathogenesis of which is yet to be understood. SLE is considered to be a multifactorial disease, in which genetic factors, immune dysregulation, and environmental factors, such as ultraviolet radiation, are involved. Recently, the description of novel genes conferring susceptibility to develop SLE even in their own (monogenic lupus) has raised the interest in DNA dynamics since many of these genes are linked to DNA repair.

The IL-17 cytokine family and the cognate receptors thereof have a unique role in organ-specific autoimmunity. Most studies have focused on the founding member of the IL-17 family, IL-17A, as the central mediator of diseases. Indeed, although pathogenic functions have been ascribed to IL-17A and IL-17F in the context of immune-mediated glomerular diseases, the specific functions of the other IL-17 family members in immunity and inflammatory kidney diseases is largely unknown.

Are the unenhanced and excretory CT phases necessary for the evaluation of acute pyelonephritis?

Acta Radiol 2017 May 30;58(5):634-640. Epub 2016 Sep 30.

1 Department of Imaging, Universidade Federal de São Paulo, São Paulo, Brazil.

Background The most widely accepted computed tomography (CT) protocol for diagnosis of acute pyelonephritis (APN) includes at least a pre- and post-contrast scan, which may expose patients to higher doses of ionizing radiation. Purpose To establish the accuracy, reproducibility, and degree of confidence in CT diagnosis of acute pyelonephritis (APN) and urolithiasis using only images obtained during the nephrographic phase. Material and Methods A retrospective study of 100 consecutive patients (88 women; age range, 19-70 years) with clinical and laboratory suspicion of APN and who underwent triphasic abdominal CT scans (non-contrast, nephrographic, and excretory phases) was performed.

Lessons from a double-transgenic neutrophil approach to induce antiproteinase 3 antibody-mediated vasculitis in mice.

J Leukoc Biol 2016 12 30;100(6):1443-1452. Epub 2016 Jun 30.

Experimental and Clinical Research Center, Charité, Universitätsmedizin Berlin, Max Delbrück Center for Molecular Medicine in the Helmholtz Association, Berlin, Germany;

ANCA to either PR3 or MPO are found in patients with necrotizing vasculitis and glomerulonephritis. ANCA binding to their target antigens on neutrophils and subsequent neutrophil activation are pivotal disease mechanisms that lead to vascular inflammation and necrosis. ANCA interaction with PR3 is more complex than with MPO as the neutrophil-specific CD177 receptor is involved in PR3 surface expression and PR3-ANCA-induced neutrophil activation. Read More

Classifying murine glomerulonephritis using optical coherence tomography and optical coherence elastography.

J Biophotonics 2016 08 21;9(8):781-91. Epub 2016 Jan 21.

Department of Biomedical Engineering, University of Houston, 3605 Cullen Boulevard, Houston, Texas, 77204, USA.

Acute glomerulonephritis caused by antiglomerular basement membrane marked by high mortality. The primary reason for this is delayed diagnosis via blood examination, urine analysis, tissue biopsy, or ultrasound and X-ray computed tomography imaging. Blood, urine, and tissue-based diagnoses can be time consuming, while ultrasound and CT imaging have relatively low spatial resolution, with reduced sensitivity. Read More

FDG PET/CT Appearance of Radiation Nephritis.

Clin Nucl Med 2016 Mar;41(3):253-4

From the *Division of Nuclear Medicine and Molecular Imaging, Department of Radiology, Brigham and Women's Hospital; and †Harvard Medical School, Boston, MA.

It is often challenging to assess renal activity on FDG-PET/CT due to intense physiological activity in the collecting system, thus any unusual intrarenal activity should be evaluated carefully. While increased bone tracer uptake in the irradiated region of the kidneys has been reported in the literature, altered biodistribution of FDG in irradiated renal tissue is not well described. We report a case of FDG PET/CT showing increased FDG activity in small portions of the kidneys that were previously irradiated. Read More

Acute pyelonephritis in children.

Pediatr Nephrol 2016 08 4;31(8):1253-65. Epub 2015 Aug 4.

Pediatric Nephrology and Dialysis Unit, Department of Clinical Sciences and Community Health, University of Milan Fondazione IRCCS Cà Granda -Ospedale Maggiore Policlinico Via della Commenda, 9 20122, Milano, Italy.

Acute pyelonephritis is one of the most serious bacterial illnesses during childhood. Escherichia coli is responsible in most cases, however other organisms including Klebsiella, Enterococcus, Enterobacter, Proteus, and Pseudomonas species are being more frequently isolated. In infants, who are at major risk of complications such as sepsis and meningitis, symptoms are ambiguous and fever is not always useful in identifying those at high risk. Read More
