Acute lymphoblastic leukemia diagnosed by renal biopsy

Area of Science:

• Pediatric Nephrology
• Pediatric Hematology-Oncology

Background:

• Acute kidney injury (AKI) in children can have diverse etiologies.
• Leukemia is a known, though less common, cause of renal complications in pediatric patients.

Observation:

• An 8-year-old boy experienced recurrent episodes of acute non-oliguric renal failure.
• Initial hematological tests and kidney examinations were unremarkable, showing normal hemograms and non-enlarged kidneys.

Findings:

• A renal biopsy confirmed the diagnosis of acute lymphoblastic leukemia (ALL).
• This case highlights the importance of considering leukemia in the differential diagnosis of unexplained recurrent AKI in children.

Implications:

• The findings underscore the need for thorough diagnostic workups in pediatric patients with recurrent AKI.
• Understanding the specific mechanisms of renal failure in leukemia is vital for improving patient outcomes and guiding therapeutic strategies.
