Summary
Infectious endocarditis (IE) frequently causes kidney damage, with hematuria being a key indicator. Prompt diagnosis and treatment of renal complications in IE patients are crucial for better outcomes.
Area of Science:
- Nephrology
- Infectious Diseases
- Cardiology
Background:
- Infectious endocarditis (IE) is a serious infection affecting heart valves.
- Renal complications are a significant concern in patients with IE.
Observation:
- This study observed 113 patients with infectious endocarditis.
- Renal damage was identified in 24.7% of patients, with hematuria as the primary sign.
- Specific causes included diffuse glomerulonephritis (15%), renal infarction (5.3%), and focal glomerulonephritis (4.4%).
Findings:
- Hematuria, indicative of kidney involvement, complicates early IE diagnosis and treatment.
- Nephrotic syndrome at onset, accompanied by hematuria, led to misdiagnoses in some cases.
- Mesangioproliferative glomerulonephritis was confirmed postmortem in all observed renal damage cases, often with renal infarction.
Implications:
- Early detection and characterization of renal damage in IE are vital for patient prognosis.
- Antibacterial therapy for IE led to hematuria resolution in 14.1% (complete) and 3.5% (partial) of patients.
- Untreated renal damage in IE can progress to fatal chronic renal failure.
