In this study, risk factors, clinical features, outcomes and factors associated with mortality in nocardia pneumonia were reported.Materials and Methods:Clinical records of all cases diagnosed with nocardia pneumonia during 2001-2010 were reviewed. Identification of Nocardia species was based on positive Gram stain and positive modified acid-fast stain results, colonial morphology, and conventional biochemical reactions. Data was analyzed using SPSS version 17. Factors associated with mortality was assessed by univariate and multivariate analysis.Results:Fifty Five cases were identified. Fever, cough and dyspnea were the most common presentations. Most important risk factors were chronic steroid administration (69%) and an underlying malignancy (24%). Most common complications observed were respiratory failure (27%) and septicemia (27%). 19(34.5%) patients died. Factors associated with mortality were Smoking (p 0.01), decreased appetite (p 0.007), leukocytosis (p 0.006), mechanical ventilation (p <0.001) and septicemia (p <0.001). Septicemia (OR 20 [95% CI 3.13 -130] was found to be independent risk factor for mortality on multivariate analysis.Conclusion:We report underlying malignancy and chronic corticosteroid therapy as a risk factor for development of nocardiosis in our patients. High mortality rate in this cohort were observed. Septicemia was found to be independent risk factor for mortality. Clinicians should keep a high index of suspicion for early diagnosis and management to decrease mortality. %U https://erj.ersjournals.com/content/erj/40/Suppl_56/P2541.full.pdf
