Treatment of legionnaires' disease

Abstract:
Erythromycin has been the most commonly used drug for the treatment of legionnaires' disease; however, failures have occurred and adverse effects are common. Doxycycline intravenously is preferred and is less expensive. The newer macrolides/azalides, clarithromycin and azithromycin, have excellent in vitro activity against Legionella and fewer adverse effects than erythromycin. The fluoroquinolones, particularly levofloxacin, are the most active anti-Legionella antibiotics available. Other agents with activity against Legionella pneumophila include minocycline, rifampin, and trimethoprim-sulfamethoxazole. The preferred therapy of legionellosis in immunocompromised patients are quinolone/macrolide combinations, eg, levofloxacin plus azithromycin.

Pneumonia IV: Management
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:
Pneumonia V: Nursing management and Prevention
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.
Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
