Clinical Report: Uncommon Case of Disseminated Talaromyces marneffei Infection
Overview
This report details a rare case of Talaromyces marneffei infection presenting as acute pancreatitis in a patient with HIV-1. The case highlights the diagnostic challenges and the need for early recognition of this life-threatening mycosis in immunocompromised individuals.
Background
Talaromyces marneffei is a significant opportunistic pathogen in immunocompromised patients, particularly those with HIV/AIDS, in endemic regions of Southeast Asia and southern China. The infection can lead to severe complications, including acute pancreatitis, which is rarely documented. Understanding the clinical manifestations and timely diagnosis of T. marneffei is crucial for improving patient outcomes.

Key Findings
The patient was a 52-year-old man with a history of HIV-1/AIDS presenting with fever and respiratory symptoms.
Blood cultures revealed filamentous fungi, later identified as Talaromyces marneffei.
Acute pancreatitis was confirmed with significantly elevated lipase levels.
Despite antifungal treatment, the patient's condition worsened, necessitating a switch to voriconazole therapy.
Clinical Implications
Healthcare professionals should maintain a high index of suspicion for Talaromyces marneffei infection in HIV patients presenting with nonspecific symptoms. Early diagnosis and appropriate antifungal treatment are critical to improving patient outcomes in this vulnerable population.
Conclusion
This case underscores the importance of recognizing Talaromyces marneffei as a potential cause of acute pancreatitis in immunocompromised patients. Timely intervention can significantly impact morbidity and mortality associated with this infection.
