ObjectiveTo study the frequency of neutropenic febrile patients who present in shock, to evaluate the influence of this presenting feature on response to antibiotic therapy, morbidity, and mortality and to identify discriminating demographic features and clinical characteristics of these individuals.MethodsProspectively collected data on all episodes of fever and neutropenia observed in cancer patients who were hospitalized for parenteral antibiotic therapy.ResultsFive hundred and seventy-six patients were evaluated; 22 (3.8%) presented in shock. This group of individuals was compared with the remainder. Patients presenting in shock were more likely to be older (P< 0.01) and have progressive unresponsive cancer (P< 0.01). They were also more likely to present with septic appearance (P< 0.01), dehydration (P< 0.01), diarrhoea (P< 0.01), altered mental status (P< 0.01) clinical bleeding (P= 0.02) and dyspnoea (P< 0.01). They more often had anaemia (P< 0.01), thrombocytopenia (P= 0.02) and abnormal liver function tests (P< 0.01). Eight of the 22 patients presenting in shock had documented bacteraemia. Non-bacteraemic microbiological infections were observed in three patients. Five patients had clinical evidence of infection and another five were severely dehydrated and volume depleted. One patient had cardiogenic shock. Three patients were managed with monotherapy, 19 received combination antibiotics as initial empirical therapy. Overall outcome of these patients was extremely poor, particularly those with infectious aetiology. Eighteen (82%) patients expired.ConclusionNeutropenic febrile patients who present in shock have extremely poor outcomes irrespective of type of initial antibiotic therapy. Intense efforts are required to improve their outcome.
