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.
Lack of ability of ciprofloxacin-rifampin prophylaxis to decrease infection-related morbidity in neutropenic patients given cytotoxic therapy and peripheral blood stem cell transplants.
We compared ciprofloxacin alone with ciprofloxacin plus rifampin (C + R) as a prophylactic antibacterial regimen for 40 patients with solid tumors treated with high-dose chemotherapy and autologous stem cell transplantation support. No differences were found between groups in the time elapsed to the onset of fever, incidence of febrile episodes, amphotericin B use, and length of hospital stay. However, C + R combination prophylaxis significantly reduced the incidence of gram-positive bacteremia (five versus zero episodes) but was associated with a higher incidence of drug-related side effects.
