Isavuconazole's (ISA) pharmacokinetics was studied among lung transplant recipients to evaluate its bronchopulmonary penetration. This study included 13 patients and showed mean serum concentrations of 3.30 (standard deviation [SD] 0.45), 5.12 (SD 1.36), and 6.31 (SD 0.95) at 2 h, 4 h, and 24 h respectively. Mean concentrations in the epithelial lining fluid were 0.969 (SD 0.895), 2.141 (SD 1.265), and 2.812 (SD 0.693) at the same time points. ISA is a drug with a tolerable safety profile that achieves adequate concentrations in the lung.

Ambroxol, a commonly used mucolytic agent, has been extensively studied for its clinical effectiveness in managing respiratory conditions in pediatric and adult patients. The existing body of research on ambroxol demonstrates its safety and efficacy. However, its potential role in preventing and treating neonatal diseases still needs to be explored.

The SARS-CoV-2 pandemic had stimulated the emergence of numerous publications on the α-proteinase inhibitor (α-PI, α-antitrypsin), especially when it was found that the regions of high mortality corresponded to the regions with deficient α-PI alleles. By analogy with the data obtained in the last century, when the first cause of the genetic deficiency of α-antitrypsin leading to elastase activation in pulmonary emphysema was proven, it can be supposed that proteolysis hyperactivation in COVID-19 may be associated with the impaired functions of α-PI. The purpose of this review was to systematize the scientific data and critical directions for translational studies on the role of α-PI in SARS-CoV-2-induced proteolysis hyperactivation as a diagnostic marker and a therapeutic target.

A bronchopulmonary fistula is a pathological connection that develops between the bronchi and the pleural cavity as a result of etiologies including surgery, infection, blunt or penetrating trauma, radiation, chemotherapy, and chronic obstructive pulmonary disease sequela. Diagnosis and treatment are challenging for intensivists. We present a case report of bronchopulmonary fistula resulting in hydropneumothorax caused by necrotizing pneumonia and complicated by mycobacterium avium complex that resolved spontaneously.
