Purpose:
Patients with hematologic malignancies (HM) are at high risk of invasive lung fungal infections (ILFI). To describe the main characteristics, treatment, and outcomes for five years in adult patients with HM and fungal pneumonia.
Methods:
We conducted a retrospective study at Instituto Nacional de Cancerología (INCan), a referral tertiary care oncology hospital with 135 beds in Mexico City, Mexico. We included all cases of fungal pneumonia in patients with HM from January 1, 2017, to December 31, 2022. Cases were classified as proven, probable, and possible according to EORTC/MSG criteria 2021.
Results:
Two hundred ten patients were included; the mean age was 40 years. The most frequent HM was acute lymphoblastic leukemia (n = 74) and acute myeloid leukemia (n = 68). One hundred forty patients (66.7%) had severe neutropenia for a median of 16 days. All patients had a CT thorax scan; in 132 (62.9%), multiple nodules were documented. Serum galactomannan (GM) was positive in 21/192 (10.9%) and bronchoalveolar lavage in 9/36 (25%). Fifty-three patients (25.2%) died in the first month. In the multivariate analysis for mortality in the first 30 days, hypoalbuminemia, shock, possible ILFI, and inappropriate antifungal treatment were statistically associated.
Conclusions:
In high-risk HM patients, CT thorax scan and GM help diagnose ILFI. An appropriate antifungal improves mortality.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

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.

The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....
