However, high-dose chemotherapy is still accompanied by dose-limiting toxicities, for example, severe mucositis. Mucosal lesions serve as portals of entry for infections. In order to reduce the oral microbial burden, we prospectively evaluated the microbiological impact of a complex regimen of mouth rinses consisting of concomitantly applied polyene antifungals, povidone-iodine, chlorhexidine, sage tea, and prophylactic ciprofloxacin and fluconazole. A total of 15 patients were enrolled into this longitudinal evaluation. Colony-forming units (CFU) were quantitated from saliva, buccal and palatinal swabs during high-dose chemotherapy and autologous stem cell transplantation. The number of CFU did not show any significant changes after initiation of the mouth rinses and the prophylactic antibiotics. The median CFU count was 268 x 10(6)/ml saliva before chemotherapy and decreased after initiation of intravenous antibiotics only. Neither prophylactic nor therapeutic antifungals significantly reduced the number of cultures positive for yeasts. Since 90% of our patients had febrile neutropenia at some time point during the observation period, the approach evaluated cannot be recommended as prophylaxis of febrile neutropenia as such. | lld:pubmed |
