Ceftriaxone Vs Levofloxacin on Cytokine Expression in Pneumococcal Pneumonia
Comparison Between Ceftriaxone and Levofloxacin on Cytokine Expression Over Time in Severe Pneumococcal Pneumonia
The purpose of this study is to compare levofloxacin vs ceftriaxone impact on the cytokine production in patients with pneumococcal pneumonia.
Bacterial alveolar invasion is followed by a compartmentalized inflammatory response. Data suggest that some antimicrobials may induce a differential release of cytokines, with the potential of either accelerating or down regulating cytokine production.
The aim of our study was to compare the effects of ceftriaxone compared with levofloxacin on cytokine systemic concentrations in patients with pneumococcal pneumonia.
Inclusion Criteria: patients with an acute febrile respiratory illness accompanied by a new radiographic infiltrate consistent with this diagnosis. and with a confirmed pneumococcal aetiology Exclusion Criteria: age < 18 years, pneumonia distal to endobronchial obstruction, pulmonary tuberculosis, bronchiectasis, known allergy to B-lactams or fluoroquinolones, underlying systemic autoimmune disease immunocompromised states including patients on maintenance oral corticosteroids, HIV infection, pregnancy, patients that received antimicrobial therapy in the 15 days preceding the current episode and those who had received fluoroquinolones in the last month, or non steroidal anti-inflammatory therapy in the last two weeks. Patients with renal failure (serum creatinine > 2 mg / dL), and patients with a documented pneumococcal pneumonia in the previous 4 weeks
