Summary
Chemotherapy can harm kidney function in patients with blood cancers, causing damage to glomeruli and tubules. Viral infections may also contribute to kidney impairment during treatment.
Area of Science:
- Nephrology
- Oncology
- Pathology
Background:
- Hematological malignancies often require intensive chemotherapy.
- Chemotherapy can have significant side effects, including potential organ damage.
- The impact of chemotherapy on kidney morphofunctional status in these patients requires detailed investigation.
Observation:
- Renal function, including concentration ability and glomerular filtration rate (GFR), was assessed.
- Kidney biopsies were performed for histological and electron-microscopic examination.
- Patients exhibited impaired renal concentration and filtration functions with minimal urinalysis changes.
Findings:
- Morphological changes included glomerular damage, tubular dystrophy, and interstitial sclerosis.
- Electron microscopy revealed structural defects in the glomerular basal membrane.
- Cytoplasmic viruses (Epstein-Barr, CMV, HSV) were detected, affecting mitochondria and podocytes, leading to dystrophic changes.
Implications:
- Chemotherapy poses a risk to both glomerular and tubular kidney systems, increasing complication probability.
- Imbalances in cell degradation product clearance and drug metabolism can lead to nephropathy.
- Viral infections, potentially linked to immunosuppression, may directly impair renal endothelium, necessitating further research into therapeutic strategies.
