Background: Studies indicate that the prevalence of multidrug-resistant infections, including hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP), has been rising. There are many challenges associated with these disease conditions and the ability to develop new treatments. Additionally, HABP/VABP clinical trials are very costly to conduct given their complex protocol designs and the difficulty in recruiting and retaining patients.
Methods: With input from clinicians, representatives from industry, and the US Food and Drug Administration, we conducted a study to (1) evaluate the drivers of HABP/VABP phase 3 direct and indirect clinical trial costs; (2) to identify opportunities to lower these costs; and (3) to compare (1) and (2) to endocrine and oncology clinical trials. Benchmark data were gathered from proprietary and commercial databases and used to create a model that calculates the fully loaded (direct and indirect) cost of typical phase 3 HABP/VABP endocrine and oncology clinical trials.
Results: Results indicate that the cost per patient for a 200-site, 1000-patient phase 3 HABP/VABP study is $89600 per patient. The cost of screen failures and screen failure rates are the main cost drivers.
Conclusions: Results indicate that biopharmaceutical companies and regulatory agencies should consider strategies to improve screening and recruitment to decrease HABP/VABP clinical trial costs.

Streptococcus pneumoniae is a major pathogen of bacterial pneumonia, meningitis, sepsis, and otitis media. The pathogenicity of this bacterium is largely attributed to its polysaccharide capsule, a protective layer around bacterial cell that enables bacteria to resist against host defense. Capsular polysaccharides (CPSs) of S.

Streptococcus pneumoniae (Sp; pneumococcus), the most common agent of community-acquired pneumonia, can spread systemically, particularly in the elderly, highlighting the need for adjunctive therapies. The airway epithelial barrier defends against bacteremia and is dependent upon apical junctional complex (AJC) proteins such as E-cadherin. After mouse lung challenge, pneumolysin (PLY), a key Sp virulence factor, stimulates epithelial secretion of an inflammatory eicosanoid, triggering the infiltration of polymorphonuclear leukocytes (PMNs) that secrete high levels of neutrophil elastase (NE), thus promoting epithelial damage and systemic infection.

Objective: To evaluate the therapeutic potential of fecal microbiota transplantation (FMT) in treating severe pneumonia patients with concurrent pan-drug resistant infection.
Methods: A case report of a 95-year-old female patient with severe pneumonia, complicated by pan-resistant bacterial infections, is presented. The patient was diagnosed with severe pneumonia caused by COVID-19, along with co-infections of , , , , ESBL-producing pan-drug resistant and pan-resistant .

Influenza, a highly contagious respiratory viral illness, poses significant global health risks, particularly affecting older and those with chronic health conditions. Influenza viruses, primarily types A and B, are responsible for seasonal human infections and exhibit a propensity for antigenic drift and shift, contributing to seasonal epidemics and pandemics. The severity of influenza varies, but severe cases often lead to pneumonia, acute respiratory distress syndrome, and multiorgan failure.
