Community Acquired Pneumonia in Bangladesh: Sensitivity Pattern, Clinical Courses and Outcome of a Cross Sectional Population
Abstract
Background: Pneumonia acquired outside the hospital by an immune-competent individual is defined as community acquired pneumonia (CAP). It is to be distinguished, on the basis of a wider spectrum of pathogens, from nosocomial pneumonia from pneumonia in an immune-compromised host. Community-acquired pneumonia is associated with a significant mortality and morbidity. Etiology of CAP varies geographically and the understanding of local epidemiology plays an important role in decision making for empirical treatment before test results are available. Primary decisions about empirical antimicrobial treatment required knowledge of predominant microbial patterns and their sensitivities.
Objectives: The aim of this study was to identify the bacterial etiology of CAP, their sensitivity towards empirical therapy and to observe the clinical course as well as short term outcome in hospitalized adult patients.
Methodology: It was one year-long observational prospective study on 87 patients diagnosed with CAP admitted in Chattogram Medical College Hospital, second largest tertiary care hospital during August 2018 to July 2019. Sputum for Gram and Z-N staining, culture and sensitivity, blood for culture, sensitivity and PCR for Streptococcus pneumonia, Mycoplasma pneumoniae, Legionella pneumophila and Chlamydophila pneumonia were done. Patients were followed up for in-hospital outcome and 30-day mortality.
Results: The mean age was 49.59 years and male - female ratio was 1.56: 1. Fever,…
