Pleural effusion Due to Streptococcus milleri: Case descriptions.

Area of Science:

• Infectious Diseases
• Pulmonology
• Microbiology

Background:

• Pleural effusion is a significant clinical condition.
• Streptococcus milleri is an uncommon cause of pleural effusion.
• Understanding patient characteristics and treatment outcomes is crucial.

Purpose of the Study:

• To analyze the clinical characteristics of patients with pleural effusion caused by Streptococcus milleri.
• To evaluate the treatment strategies and outcomes for this specific patient group.

Main Methods:

• Retrospective analysis of seven patients diagnosed with Streptococcus milleri pleural effusion between January and March 2013.
• Data collection included patient demographics, comorbidities, bacterial identification, treatment duration, and hospitalization length.

Main Results:

• The mean patient age was 60 years, with 43% smokers and 57% with a history of alcohol consumption.
• Common associated factors included alcoholism, prior pneumonia, and diabetes.
• Mean antibiotic therapy lasted 28 days; six patients required chest tube drainage, and one needed surgery.
• Mean hospitalization was 30 days, with all patients achieving satisfactory outcomes despite residual functional changes.

Conclusions:

• Streptococcus milleri can cause pleural effusion, often in patients with significant comorbidities.
• Standard treatment involving antibiotics and pleural drainage leads to favorable outcomes.
• Prompt management is essential for resolving pleural effusion and ensuring patient recovery.
