Pleural infection: past, present, and future directions.

Area of Science:

• Pulmonology
• Infectious Diseases
• Thoracic Surgery

Background:

• Pleural space infections are increasing, leading to high morbidity and mortality.
• Pathogen entry routes into the pleural space remain poorly understood, with some cases unrelated to pneumonia.
• Microbiological profiling is crucial for guiding antibiotic selection and understanding infection sources.

Purpose of the Study:

• To review current understanding of pleural infection pathogenesis and treatment.
• To highlight the importance of radiological methods and clinical indices for outcome prediction.
• To discuss the role of intrapleural tissue plasminogen activator and deoxyribonuclease therapy versus surgical options.

Main Methods:

• Literature review of scientific data on pleural infections.
• Analysis of studies on microbiological profiles and pathogenesis.
• Examination of randomized clinical trials and case series on treatment efficacy.

Main Results:

• The precise route of pathogen access to the pleural space is not fully elucidated.
• Radiological and clinical tools are vital for predicting poor outcomes and guiding treatment.
• Intrapleural tissue plasminogen activator and deoxyribonuclease show potential but require further comparative definition against surgery.

Conclusions:

• Understanding pleural infection mechanisms is critical for improving patient care.
• Predictive tools and refined treatment strategies are needed to manage these complex infections.
• Further research is necessary to define optimal therapeutic pathways, including the role of novel intrapleural therapies.
