| Introducion: Pneumonia is still the most common cause of human death due to infectious disease. The causative agent of pneumonia is often undetectable. Regarding the need of correct and in time treatment of patients suffering from CAP, we carried out this study to evaluate the clinical, laboratory and radiologic findings in adults suffered from acute community acquiredPneumonia.
Materials and methods: In this study we evaluated 152 patients with mean age 60.86( 19-92 ) year, with initial clinical diagnosis of Community Acquired Pneumonia)CAP (presented to the Emergency department. A check-list was completed for each patient based on their demographic informations,. Finally we compared the diagnostic value of different finding with each other. The data was collected, entered into SPSS and was analyzed by (α=0.05).
Findings: Acute bacterial CAP as a final diagnosis was confirmed in 50% of the patients under study. The most common clinical signs and symptoms were fever, cough, sputum and abnormal breath sounds on examination. Microbiologically, among 121 cases whom specimens were cultured, 20 cases were culture positive for lung pathogens. The most common germ was Staphylococcus Aureus (7 cases ), then Pneumococcus, Klebsiella ، pseudomonas and Moraxella Catarrhalis were the next. The most common radiologic pattern noted was petechial infiltration (42.8%) then lobar infiltration (9.2%) and in 23% of patients no abnormal radiologic finding was noted. In this study laboratory diagnosis had sensitivity = 22/37% and specificity = 96.05%. For radiologic diagnosis sensitivity = 100% and specificity = 89.47%, in case of CRP positive sensitivity = 90.79% and specificity = 50%.
Discussion and Conclusion: in this study CXR was the best way for the diagnosis of CAP., If this diagnostic test was inaccessible, valuable clinical signs and symptoms which were cough, sputum, fever and abnormal breath sounds in combination with. CRP and WBC count are beneficial in of CAP. |
