Trichosporon beigelii: a potential cause of sepsis in premature infants
1Division of Neonatology, University of Oklahoma College of Medicine-Tulsa.
Abstract:
Trichosporon beigelii is an emerging pathogen, often resistant to amphotericin B, that causes disseminated infection in immunocompromised patients. Early identification of this organism and knowledge of sensitivity patterns to antifungal agents may decrease the high mortality rate for immunocompromised patients with disseminated trichosporosis. I have reported a case of septicemia associated with T beigelii in a premature twin infant who had been granulocytopenic since birth.
Insights
Trichosporon beigelii causes severe infections in immunocompromised individuals and is often resistant to amphotericin B. Early diagnosis and antifungal sensitivity testing are crucial for improving outcomes in disseminated trichosporosis.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Immunocompromised Host Research
Background:
- Trichosporon beigelii is an emerging fungal pathogen.
- This organism frequently exhibits resistance to amphotericin B, a common antifungal medication.
- Disseminated trichosporosis poses a significant threat to immunocompromised patients.
Observation:
- A case of septicemia caused by T beigelii is presented.
- The affected patient was a premature twin infant.
- The infant had a history of granulocytopenia since birth.
Findings:
- Trichosporon beigelii is an emerging pathogen causing disseminated infections.
- The organism demonstrates resistance to amphotericin B.
- Early identification and antifungal sensitivity are key to managing T beigelii infections.
Implications:
- Timely diagnosis and targeted antifungal therapy can reduce mortality in disseminated trichosporosis.
- Understanding T beigelii resistance patterns is vital for effective treatment strategies.
- This case highlights the vulnerability of granulocytopenic infants to invasive fungal infections.
