Summary
Hantavirus infection can cause acute kidney injury, presenting as non-ischemic renal failure. Early serological testing for hantavirus antibodies is crucial for diagnosis and prompt treatment, leading to full recovery.
Area of Science:
- Nephrology
- Infectious Diseases
- Virology
Background:
- Non-ischemic acute renal failure necessitates investigation into potential infectious etiologies.
- Hantavirus infection is a recognized cause of acute kidney injury, often presenting with distinct clinical and pathological features.
Observation:
- A 19-year-old male presented with acute febrile illness, rhinitis, arthralgia, polyuric renal failure, hypertension, and urinalysis abnormalities.
- Serological tests confirmed IgG and IgM antibodies against the Dobrava hantavirus (Central European variant).
Findings:
- Renal biopsy revealed tubular damage (swelling, vacuolization, necrosis) and interstitial hemorrhages.
- Electron microscopy identified hantavirus virions within the renal tubular cells' nucleus and cytoplasm.
Implications:
- This case highlights the importance of considering hantavirus nephropathy in patients with unexplained acute renal failure.
- Prompt diagnosis through serological examination and appropriate management can lead to complete renal recovery (restitutio ad integrum).
