Abstract:
Human pythiosis is an infectious condition with high morbidity and mortality. The causative agent is the oomycete microorganism Pythium insidiosum. The pathogen inhabits ubiquitously in a wet environment, and direct exposure to the pathogen initiates the infection. Most patients with pythiosis require surgical removal of the affected organ, and many patients die from the disease. Awareness of pythiosis among healthcare personnel is increasing. In this review, we summarized and updated information on the diagnosis and treatment of human pythiosis. Vascular and ocular pythiosis are common clinical manifestations. Recognition of the typical clinical features of pythiosis is essential for early diagnosis. The definitive diagnosis of the disease requires laboratory testing, such as microbiological, serological, molecular, and proteomic assays. In vascular pythiosis, surgical intervention to achieve the organism-free margin of the affected tissue, in combination with the use of antifungal drugs and P. insidiosum immunotherapy, remains the recommended treatment. Ocular pythiosis is a serious condition and earliest therapeutic penetrating keratoplasty with wide surgical margin is the mainstay treatment. Thorough clinical assessment is essential in all patients to evaluate the treatment response and detect an early sign of the disease recurrence. In conclusion, early diagnosis and proper management are the keys to an optimal outcome of the patients with pythiosis.
Insights
Human pythiosis, caused by Pythium insidiosum, is a severe infection requiring prompt diagnosis and treatment. Early recognition of clinical signs and appropriate management, including surgery and immunotherapy, are crucial for patient survival.
Area of Science:
- Infectious Diseases
- Mycology
- Oomycete Infections
Background:
- Human pythiosis is a severe infectious disease caused by the oomycete Pythium insidiosum.
- The pathogen is found in wet environments, and infection occurs through direct exposure.
- High morbidity and mortality rates underscore the need for increased awareness and effective interventions.
Purpose of the Study:
- To review and update current knowledge on the diagnosis and treatment of human pythiosis.
- To highlight common clinical manifestations, including vascular and ocular pythiosis.
- To emphasize the importance of early diagnosis and comprehensive management strategies.
Main Methods:
- Review of existing literature on human pythiosis.
- Summary of diagnostic approaches including microbiological, serological, molecular, and proteomic assays.
- Analysis of treatment strategies for vascular and ocular pythiosis.
Main Results:
- Vascular and ocular pythiosis are common presentations.
- Early diagnosis relies on recognizing clinical features and laboratory confirmation.
- Recommended treatment for vascular pythiosis involves surgery, antifungals, and Pythium insidiosum immunotherapy.
- Penetrating keratoplasty with wide surgical margins is key for ocular pythiosis.
Conclusions:
- Early diagnosis and prompt, appropriate management are critical for improving patient outcomes in human pythiosis.
- Continued clinical assessment is vital for monitoring treatment response and detecting recurrence.
- Increased awareness among healthcare professionals is essential for timely intervention.
