Antibiotic prophylaxis in afebrile neutropenic patients significantly reduced all-cause mortality. In our review, the most significant reduction in mortality was observed in trials assessing prophylaxis with quinolones. The benefits of antibiotic prophylaxis outweighed the harm such as adverse effects and the development of resistance since all-cause mortality was reduced. As most trials in our review were of patients with haematologic cancer, we strongly recommend antibiotic prophylaxis for these patients, preferably with a quinolone. Prophylaxis may also be considered for patients with solid tumours or lymphoma.
Antimicrobial prophylaxis in immunocompromised patients.
The results of a randomised, prospective trial to investigate the efficacy of prophylactic treatment with ofloxacin during granulocytopenia after cytostatic treatment are presented. 42 patients with metastasised testicular germ-cell tumours entered the study. Cytostatic treatment consisted of at least 4 courses, 2 of which were succeeded by prophylactic treatment with ofloxacin. Three patients undergoing prophylactic treatment developed fever. Fever occurred in 16 patients during control phases (no ofloxacin prophylaxis) of cytostatic treatment. Seven of the 19 infections could be documented microbiologically. No side effects that related to ofloxacin were noted. In conclusion, ofloxacin was highly effective in the prevention of infection and, therefore, should be given prophylactically to patients with granulocytopenia.
