Abstract:
AIDS patients are vulnerable to infection by opportunistic microbes, including various fungi such as Pneumocystis carinii, Cryptococcus neoformans, Histoplasma capsulatum, Candida albicans and many others. However, the association of AIDS and infection with Paracoccidioides brasiliensis has been rarely recorded. We report a case of an HIV-positive patient with bone infection by this fungus with a clinical form not previously published. This clinical presentation included primarily a massive bone lesion, but it did not include the lymphatic and disseminated disease described in HIV-positive patients. The patient responded well to medical and surgical treatment. We suggest that patients with moderate, rather than severe, immunosuppression may have forms of paracoccidioidomycosis with a pathologic process intermediate to those seen in the immunologically normal host and the full AIDS syndrome.
Insights
This study details a rare bone infection in an HIV-positive patient caused by Paracoccidioides brasiliensis. Moderate immunosuppression may lead to unique clinical presentations of paracoccidioidomycosis.
Area of Science:
- Mycology
- Infectious Diseases
- Immunology
Background:
- Acquired Immunodeficiency Syndrome (AIDS) patients are susceptible to opportunistic fungal infections.
- Infection with Paracoccidioides brasiliensis (PB) is rarely documented in patients with AIDS.
- Typical disseminated PB infections in HIV-positive individuals involve lymphatic and widespread disease.
Purpose of the Study:
- To report a novel clinical presentation of Paracoccidioides brasiliensis bone infection in an HIV-positive patient.
- To explore the relationship between the degree of immunosuppression and the clinical manifestation of paracoccidioidomycosis.
Main Methods:
- Case report of a single HIV-positive patient.
- Clinical and radiological assessment of a massive bone lesion.
- Evaluation of treatment response to medical and surgical interventions.
Main Results:
- The patient presented with a significant bone lesion as the primary manifestation of PB infection.
- Absence of typical lymphatic or disseminated disease commonly seen in AIDS patients with PB.
- Successful treatment outcome with combined medical and surgical management.
Conclusions:
- Patients with moderate immunosuppression may exhibit intermediate forms of paracoccidioidomycosis.
- This presentation differs from typical disseminated disease in severe AIDS and from infections in immunocompetent hosts.
- Highlights the importance of considering rare fungal infections in HIV-positive individuals with unusual presentations.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
