Abstract:
Here, we report a patient developing a postoperative peritoneal infection by Aspergillus fumigatus. While galactomannan serum levels were negative throughout the time course, galactomannan levels in peritoneal fluids yielded high results. Serological testing of peritoneal fluids for fungal antigens might be a useful and easily applicable tool to support diagnosis of intraabdominal aspergillosis, which represents a rare type of invasive fungal infection.
Insights
Diagnosing intraabdominal aspergillosis can be challenging. Peritoneal fluid galactomannan testing, unlike serum testing, can aid in detecting Aspergillus fumigatus infections post-surgery.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Surgical Infections
Background:
- Intraabdominal aspergillosis is a rare but serious invasive fungal infection.
- Accurate and timely diagnosis is crucial for effective treatment.
- Standard diagnostic methods may not always be sufficient.
Observation:
- A patient developed a postoperative peritoneal infection caused by Aspergillus fumigatus.
- Serum galactomannan levels remained negative throughout the observation period.
- Galactomannan levels in peritoneal fluid samples were significantly elevated.
Findings:
- Peritoneal fluid galactomannan testing demonstrated high sensitivity for diagnosing intraabdominal aspergillosis.
- Serum galactomannan testing was insufficient for diagnosing this specific case.
- This highlights a potential discrepancy between systemic and localized fungal markers.
Implications:
- Serological testing of peritoneal fluid for fungal antigens is a valuable diagnostic adjunct.
- This method may improve the early detection of invasive intraabdominal aspergillosis.
- Easily applicable diagnostic tools are needed to support clinical decision-making in rare fungal infections.
