Introduction:
Penicilliosis is caused by Penicillium marneffei, a dimorphic fungus endemic in southeast Asia and southern China. Since 1988, this deep mycosis has been one of the most frequent opportunistic infections in subjects with HIV infection in this region. We report the first observation of penicilliosis in Laos in a subject infected by HIV.
Case:
A Laotian women with HIV infection and under treatment for tuberculosis, was hospitalized with a cough, fever and cervical lymphadenopathy. A lymph node smear stained with RAL 555 confirmed the diagnosis of penicilliosis. The histologic examination detected some Penicillium marneffei, stained by PAS and Gomori-Grocot. The patient was treated successfully with ketoconazole.
Discussion:
Penicilliosis is endemic in southeast Asia. Especially in Thailand, it is a common opportunistic infection in HIV-infected persons. This case confirms the existence of penicilliosis in Laos, where its prevalence as an opportunistic infection is probably underestimated. The diagnostic method (slide stained with RAL 555) used in this case is simple, rapid, and appropriate for countries with limited economic resources to devote to the penicilliosis diagnosis.
Insights
Penicilliosis, a fungal infection caused by Penicillium marneffei, is reported for the first time in Laos in an HIV-positive patient. This highlights the importance of accessible diagnostic methods for opportunistic infections in Southeast Asia.
Area of Science:
- Mycology
- Infectious Diseases
- Public Health
Background:
- Penicilliosis is a deep mycosis caused by Penicillium marneffei, a fungus endemic to Southeast Asia.
- It is a significant opportunistic infection in individuals with Human Immunodeficiency Virus (HIV) in the region.
- The study reports the first documented case of penicilliosis in Laos.
Observation:
- A Laotian woman with HIV and tuberculosis presented with cough, fever, and lymphadenopathy.
- Diagnosis was confirmed via lymph node smear using RAL 555 stain and histological examination.
- The patient received successful treatment with ketoconazole.
Findings:
- This case confirms the presence of Penicillium marneffei infection in Laos.
- Penicilliosis is likely underestimated as an opportunistic infection in HIV-positive individuals in Laos.
- The RAL 555 staining method is a simple, rapid, and cost-effective diagnostic tool.
Implications:
- Highlights the need for increased awareness and surveillance of penicilliosis in Laos.
- Emphasizes the utility of basic diagnostic techniques in resource-limited settings for managing opportunistic mycoses.
- Underscores the significant burden of opportunistic infections in HIV patients in Southeast Asia.
