The organic Se compounds (particularly selenomethionine [SeMet]) in plants and yeasts are very effective chemoprotectants for mammalian cancer. To characterize the dynamics of selenomethionine utilization pathways, we intravenously injected (82)Se-enriched SeMet into mice under different nutritional states (Se-adequate and Se-deficient mice) and then measured their endogenous and exogenous (82)Se levels. Furthermore, we quantified Se compounds and selenoproteins in liver, kidneys, plasma, and urine. The average recoveries of exogenous (82)Se from solid tissues, urine, and feces were 81% for Se-adequate mice and 84% for Se-deficient mice...

Fluoroquinolones are broad-spectrum antibiotics increasingly utilized as empirical or prophylactic therapy in the management of cancer patients. We evaluated the effects of newer generation fluoroquinolones on the level of gastrointestinal (GI) colonization by Candida albicans in a previously established mouse model. Adult male Crl:CD1 (ICR) BR mice were fed chow containing Candida albicans or regular chow. The mice fed the Candida chow had their gut colonized by the yeast. Both groups were subsequently given levofloxacin, moxifloxacin, prulifloxacin or normal saline for 10 days...

An open, prospective, randomized pilot study was performed to assess the efficacy and safety of oral fluconazole 3 mg/kg once daily compared with oral nystatin 50,000 units/kg/day in four divided doses in preventing candida infections in 50 children undergoing remission induction or consolidation therapy for cancer. In 21 of 25 fluconazole-treated and 20 of 25 nystatin-treated patients the overall outcome of prophylaxis was clearly successful. Mild and transient oropharyngeal candidosis was observed in two and three patients in the fluconazole and nystatin groups respectively...

This study evaluated the effects of broad-spectrum antibiotics on the gastrointestinal (G.I.) yeast flora of humans and correlated the findings with those obtained from a mouse model of G.I. colonization by Candida albicans. We prospectively studied 46 adult cancer patients who received one of five broad-spectrum antibiotics (ceftriaxone, ceftazidime, ticarcillin-clavulanic acid, imipenem-cilastatin, and aztreonam) as therapy for infections. Quantitative examination of yeast colonization of stools was conducted at the baseline, at the end of antibiotic treatment, and 1 week after discontinuation of therapy...

The effects of four antibiotics on the yeast flora of the human gut were evaluated. Forty adult cancer patients who received therapy with amoxicillin-clavulanate, ciprofloxacin, sulfamethoxazole-trimethoprim or ampicillin were studied prospectively. Quantitative stool cultures for yeasts were performed immediately before, at the end of and one week after the end of the antibiotic treatment. Amoxicillin-clavulanate caused a higher and more persistent increase in gastrointestinal colonization by yeasts compared to ciprofloxacin, sulfamethoxazole-trimethoprim or ampicillin...

The ecologic effect of empiric systemic antibiotic therapy on the endogenous microflora was evaluated in 83 febrile granulocytopenic patients with cancer who were randomly allocated to receive moxalactam plus ticarcillin (45 patients) or tobramycin plus ticarcillin (38 patients) for suspected infection. Serial surveillance cultures of the nasal passages, oropharynx and feces performed twice a week showed that patients who received the former regimen had higher elimination rates and significantly lower acquisition rates (p = 0...

The effects of newly available broad-spectrum antibiotics, used for infection prophylaxis and therapy in cancer patients, on faecal aerobic and anaerobic bacteria were investigated. Quantitative and qualitative aerobic and anaerobic cultures were performed in 34 patients before therapy and between the sixth and eleventh day of therapy. Of the two prophylactic regimens norfloxacin plus amphotericin-B eliminated Enterobacteriaceae and enterococci without encouraging growth of yeasts or Clostridium difficile whereas trimethoprim-sulphamethoxazole did not eliminate enterococci and colonization with toxin producing C...
