Abstract
e20586 Background: Febrile neutropenia (FN) and myelosupression remain a challenging oncologic medical emergency and dose limiting toxicity of chemotherapy. Various factors have been studied to be associated and affect outcome of patients admitted with FN. Electrolyte abnormalities have commonly been observed, but the real incidence and impact has been only scarcely studied. This study was conducted with the aim to observe the trends of electrolyte abnormalities seen synchronously in patients admitted with chemotherapy induced febrile neutropenia and their possible influence on the outcomes. Methods: This was a prospective, observational study. A total of 215 patients admitted with FN between January 2007 and August 2008 were included. Analysis of data was made using SPSS version16.0. Toxicity profile was graded according to CTC version 3.0. Results: Febrile neutropenia was seen to be almost equally distributed among patients with solid or hematological malignancies. Males and females were seen to be affected almost equally as well. A total of 83.5% patients demonstrated some degree of electrolyte abnormalities. Hypokalemia, of any grade, was seen in 48% of patients, 51.4% having grade I, 33.3% grade III and 15.2% had grade IV hypokalemia. Hyponatremia of all grades was seen in 67.9% patients, 60.3% had Grade I, 33.3% grade III and 0.7% patients had grade IV hyponatremia. Hypomagnesaemia was seen in 54.3% patient, 94.7% having grade I decline. About 12% of patients with electrolyte deficit also had a co-existing Vomiting or diarrhea or both. Average length of stay was 5.7 days in patients having coexisting electrolyte abnormalities, compared to 4.2 days in those who had not. Out of 90 patients who requires special care unit 75 had electrolyte abnormalities, of 15 patients who expired 13 had electrolyte abnormalities. Conclusions: This analysis, which is perhaps first of its kind, suggests that electrolyte abnormalities are frequently observed in patients presenting with FN, independent of co existing vomiting or diarrhea. They can have a negative affect on the outcome such patients. Therefore the incidence and impact of electrolytes abnormalities on FN outcomes should be elaboratively studied further.
