Summary
Ifosfamide chemotherapy can lead to end-stage renal disease due to toxic effects on kidney tubules. This drug-induced kidney damage may result from specific transporter uptake in the proximal tubules.
Area of Science:
- Nephrology
- Oncology
- Toxicology
Background:
- A 67-year-old male patient with soft tissue sarcoma received neoadjuvant radiochemotherapy including doxorubicin and ifosfamide.
- Following treatment, the patient experienced progressive renal failure.
Observation:
- Elevated plasma creatinine to 4.5 mg/dl.
- Detection of glucosuria and α1-microglobulinuria.
- Renal biopsy revealed significant tubular injury, consistent with a toxic effect.
Findings:
- Histologic analysis showed normal glomeruli but severely damaged tubules.
- Conservative therapy failed, leading to uremic syndrome requiring hemodialysis.
- Kidney function did not recover despite preserved diuresis.
Implications:
- Ifosfamide can cause end-stage renal disease through tubulotoxicity.
- This nephrotoxicity may involve selective uptake by the organic cation transporter 2 (OCT2) in proximal tubules.
- Understanding the mechanism of ifosfamide-induced nephrotoxicity is crucial for patient management and developing preventative strategies.

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

01:28Kidney Transplant I: Introduction
827
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
