Chronic glomerular and tubular nephrotoxicity is reported in 20-50% and 20-25%, respectively, of children and adolescents treated with ifosfamide and 60-80% and 10-30%, respectively, of those given cisplatin. Up to 20% of children display evidence of chronic glomerular damage after unilateral nephrectomy for a renal tumour. Overall, childhood cancer survivors have a ninefold higher risk of developing renal failure compared with their siblings. Such chronic nephrotoxicity may have multiple causes, including chemotherapy, radiotherapy exposure to kidneys, renal surgery, supportive care drugs and tumour-related factors...

Untargeted metabolite profiling using high-resolution mass spectrometry coupled with liquid chromatography (LC-HRMS), followed by data analysis with the Compound Discoverer 2.0™ software, was used to study the metabolism of imatinib in humans with chronic myeloid leukemia. Plasma samples from control (drug-free) and patient (treated with imatinib) groups were analyzed in full-scan mode and the unknown ions occurring only in the patient group were then, as potential imatinib metabolites, subjected to multi-stage fragmentation in order to elucidate their structure...

BACKGROUND: Cisplatin (Cis), carboplatin (Carb), and ifosfamide (Ifos) are common nephrotoxic chemotherapies. Biomarkers of tubular injury may allow for early acute kidney injury (AKI) diagnosis. PROCEDURE: We performed a two-center (Canada, United States) pilot study to prospectively measure serum creatinine (SCr), urine neutrophil gelatinase-associated lipocalin (NGAL), and interleukin-18 (IL-18) in children receiving Cis/Carb (27 episodes), Ifos (30 episodes), and in 15 hospitalized, nonchemotherapy patients...

Cyclosporine (CSA) and nonsteroidal antiinflammatory drugs (NSAIDs) are used together to manage arthritic disorders with an immune component. Previous reports showed contrasting effects for NSAIDs on CSA nephrotoxicity and acute elevations in blood pressure. Both effects were ameliorated or exaggerated after selective cyclooxygenase-2 (COX2) and nonselective COX inhibition, respectively. Here we investigated: (i) the interaction of CSA with NSAIDs possessing variable COX1/COX2 selectivities on hemodynamic, left ventricular (LV) and cardiac autonomic and histologic profiles, and (ii) role of NADPH-oxidase (NOX)/Rho-kinase (ROCK) pathway in the interaction...

Nephrotoxicity is one of major side effects of cisplatin in chemotherapy. Therefore, there is an urgent medical need to develop drugs that may protect kidney from toxicity. In previous study, we found that it showed the protective effects of formononetin against apoptosis by upregulating Nrf2. In this study, we investigated the renoprotective effect of formononetin against cisplatin-induced AKI and tried to elucidate the possible mechanisms. The amelioration of renal function, histopathological changes, and apoptosis in tubular cells was observed after formononetin treatment...

Acute kidney injury (AKI) is a common and morbid complication after severe burn, with an incidence and mortality as high as 30% and 80%, respectively. AKI is a broad clinical condition with many etiologies, which makes definition and diagnosis challenging. The most recent Kidney Disease: Improving Global Outcomes (KDIGO) consensus guidelines defined stage and severity of AKI based on changes of serum creatinine and urine output (UOP) across time. Burn-related kidney injury is typically classified as early (0-3days after injury) or late (4-14days after injury)...

AIM: To evaluate molecular mechanisms of tissue-protective effects of antioxidants selenomethionine (SeMet) and D-pantethine (D-Pt) applied in combination with doxorubicin (Dx) in B16 melanoma-bearing-mice. METHODS: Impact of the chemotherapy scheme on a survival of tumor-bearing animals, general nephro- and hepatotoxicity, blood cell profile in vivo, and ROS content in B16 melanoma cells in vitro was compared with the action of Dx applied alone. Nephrotoxicity of the drugs was evaluated by measuring creatinine indicator assay, hepatotoxicity was studied by measuring the activity of ALT/AST enzymes, and myelotoxicity was assessed by light microscopic analysis of blood smears...

Background: Patients with cancer are at high risk for severe sepsis and septic shock (SS/SSh), and a delay in receiving effective antibiotics is strongly associated with mortality. Delays are due to logistics of clinic flow and drug delivery. In an era of increasing antimicrobial resistance, combination therapy may be superior to monotherapy for patients with SS/SSh. Patients and Methods: At the Seattle Cancer Care Alliance, we implemented the Sepsis STAT Pack (SSP) program to simplify timely and effective provision of empiric antibiotics and other resuscitative care to outpatients with cancer with suspected SS/SSh before hospitalization...

Kidney toxicity is a major problem both in drug development and clinical settings. It is difficult to predict nephrotoxicity in part because of the lack of appropriate in vitro cell models, limited endpoints, and the observation that the activity of membrane transporters which plays important roles in nephrotoxicity by affecting the pharmacokinetic profile of drugs is often not taken into account. We developed a new cell model using pseudo-immortalized human primary renal proximal tubule epithelial cells. This cell line (SA7K) was characterized by the presence of proximal tubule cell markers as well as several functional properties, including transporter activity and response to a few well-characterized nephrotoxicants...

Bradykinin appears to be an important regulator of cardiovascular function. It is also being increasingly noted as a participant in actions of drugs that affect the liver, kidney, and circulation. In our previous studies, bradykinin-potentiating factor (BPF) isolated from scorpion venom (Leiurus quinquestriatus) has been shown to be protective against hepato- and nephrotoxicity as well as healing skin burns by reducing oxidative stress in hyperglycemic conditions. Therefore, we aim to evaluate the ability of BPF in treating irradiated rats...

BACKGROUND AND OBJECTIVES: Patients with CKD are asked to perform self-management tasks including dietary changes, adhering to medications, avoiding nephrotoxic drugs, and self-monitoring hypertension and diabetes. Given the effect of aging on functional capacity, self-management may be especially challenging for older patients. However, little is known about the specific challenges older adults face maintaining CKD self-management regimens. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted an exploratory qualitative study designed to understand the relationship among factors facilitating or impeding CKD self-management in older adults...

Cisplatin is one of the most potent cytotoxic drug for the treatment of many types of cancer. However, the side effects on normal tissues, particularly on the kidney, greatly limited its use in clinic. Emerging evidence demonstrated that cisplatin could directly cause mesangial cell apoptosis, while the potential mechanism is still elusive. Here we examined the contribution of COX-2 in cisplatin-induced mesangial cell apoptosis. Firstly, we found cisplatin induced cell apoptosis in mesangial cells shown by increased number of apoptotic cells in parallel with the upregulation of Bax and the downregulation of Bcl-2...

REVIEW
Sandhya Manohar, Nelson Leung
Cisplatin is a platinum containing drug first approved as an antineoplastic agent in 1978. It remains an important and effective therapy in many forms of cancer today. Cisplatin mediates its tumorcidal effects via a number of different cytotoxic mechanisms. Although it is best known for DNA damage, cisplatin also causes cytoplasmic organelle dysfunction particularly with the endoplasmic reticulum and mitochondria. It also activates apoptotic pathways and inflicts cellular damage via oxidative stress and inflammation...

BACKGROUND: Steroid-sparing drugs, such as cyclosporine, are recommended as treatment for children with frequently relapsing nephrotic syndrome (FRNS) and steroid-related toxicities. We recently reported a high rate of relapsing nephrotic syndrome 2 years after discontinuation of cyclosporine treatment, suggesting that long-term treatment is necessary. Cyclosporine-associated nephrotoxicity (CAN) is a potential side effect of long-term cyclosporine treatment. METHODS: We retrospectively reviewed pediatric patients with FRNS treated with cyclosporine for ≥3 years at a single center between 1999 and 2012...
