Abstract:
The occurrence of invasive pulmonary aspergillosis is unusual during the course of AIDS. Patients at risk have a CD4 T-lymphocyte count under 50 cells/mm(3) combined with other risk factors in 50% of the cases. Positive diagnosis is based on chest CT scan imaging and isolation of Aspergillus in broncho-alveolar fluid. Detection of galactomannan antigen in serum and broncho-alveolar lavage fluid (BALF) is a reliable complementary tool in assessing the diagnosis. The first line therapy is Voriconazole. The prognosis, often severe, depends on prompt initiation of the appropriate antifungal treatment. We report two cases of invasive pulmonary aspergillosis in AIDS patients.
Insights
Invasive pulmonary aspergillosis is rare in AIDS patients, especially those with low CD4 counts. Early diagnosis via CT scans and antigen detection, followed by Voriconazole treatment, is crucial for improving outcomes.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Pulmonology
Background:
- Invasive pulmonary aspergillosis (IPA) is an uncommon opportunistic infection in patients with Acquired Immunodeficiency Syndrome (AIDS).
- Risk factors for IPA in AIDS include a CD4 T-lymphocyte count below 50 cells/mm³ and other coexisting conditions.
Observation:
- Diagnosis of IPA relies on chest computed tomography (CT) scans and isolation of Aspergillus species from bronchoalveolar lavage fluid (BALF).
- Detection of galactomannan antigen in serum and BALF serves as a valuable complementary diagnostic marker.
Findings:
- Voriconazole is the recommended first-line antifungal therapy for IPA.
- Prompt initiation of appropriate antifungal treatment significantly impacts the prognosis, which is often severe.
Implications:
- This case series highlights the importance of considering IPA in immunocompromised AIDS patients, even when it is unusual.
- Timely diagnosis and treatment are critical for managing IPA and improving patient survival in this vulnerable population.

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.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
