- Abstract
The causes of death were reviewed in 53 patients from two prospective randomized trials on the efficacy of trimethoprim/sulfamethoxazole as prophylaxis of gram-negative bacillary infection in granulocytopenic patients. Twenty-nine deaths occurred in patients treated with TMP/SMX prophylaxis while 24 occurred in patients who served as controls in the first trial. The two groups were similar, with the exception that more patients in the TMP/SMX group had acute leukemia (82 versus 50%; P less than 0.02). Microbiologically documented gram-negative rod infection preceeded death in 8/24 control patients as compared to 2/29 TMP/SMX recipients (P less than 0.02). This decrease in gram-negative related deaths was most pronounced in the patients with acute leukemia. Fatal gram-negative rod infection occurred in 7/12 control leukemic patients as compared to 2/24 TMP/SMX treated patients. Despite the reduction in numbers of gram-negative rod-related deaths, infectious deaths accounted for 16/24 and 15/29 patients in control and TMP/SMX treated patients, respectively. Similar numbers of fungal, viral, and gram-positive bacterial infections occurred in each group. Fever with pulmonary infiltrates but without proven etilogic agents were included in the category of "clinically documented infections;" 6/7 patients with fever and undiagnosed pulmonary infiltrates were in the TMP/SMX group. Prophylactic administration or oral trimethoprim/sulfamethoxazole reduces the frequency of fatal gram-negative rod infections in neutropenic patients.
