Epedimiologic, clinical profile and factors affecting the outcome in febrile neutropenia.

BACKGROUND: Febrile neutropenia (FN) is common in cancer patients particularly hematologic malignancies due to intensive cytotoxic chemotherapy. It is an important cause of morbidity, mortality and treatment delays. The risk is greater in patients with ANC < 500/ mm3 and increases dramatically in those with ANC < 100/ mm3 and duration of neutropenia more than 1 week.

AIMS AND OBJECTIVES: The purpose of this study was to evaluate the incidence, demographic characteristics, clinical profile, mortality, outcome and factors affecting the outcome in patients with febrile neutropenia (FN) admitted at our Center between January 2011 and November 2012.

MATERIALS AND METHODS: All cases of FN admitted in our Institute between January 2011 and November 2012 were analyzed. Data was analyzed using IBM statistic SPSS version 19.

RESULTS: A total of 333 episodes of FN were reviewed. Hematologic malignancies accounted for 299 (89.7%) episodes and 88% of all the episodes had grade 4 neutropenia. There was a significant association noted between high serum bilirubin, creatinine and outcome. Isolation of an organism from blood culture, positive findings on chest X-ray and fungal infection was associated with higher mortality. Association between transfusion requirements and outcome was analyzed and it was observed that patients who had multiple component transfusions vs single component ones were at a significantly higher risk of death. There were only 7 deaths noted among the patient population.

CONCLUSION: Leukemias are the leading cause of FN at our Institute. Higher bilirubin, creatinine, chest imaging favoring pneumonia, positive isolates and multiple transfusions had significant association with mortality. Large scale prospective studies are needed to determine the association of preemptive therapy with higher mortality. The outcome of high risk FN in this study is favorable.
