The occupational exposure of 21 nurses and pharmacy personnel from eight hospitals to cyclophosphamide and ifosfamide was determined by quantifying the amount of the drugs handled and by measuring the urinary excretion of the unmetabolised substances. Preparing antineoplastic drugs for intravenous treatment was the major task of all study participants. Twenty four hour urine was collected on da...

Cyclophosphamide-based regimens are front-line treatment for numerous pediatric malignancies; however, current dosing methods result in considerable interpatient variability in tumor response and toxicity. In this pediatric population, the authors' objectives were (1) to quantify and explain the pharmacokinetic variability of cyclophosphamide and 2 of its metabolites, hydroxycyclophosphamide (H...

Cyclophosphamide is a chemotherapeutic agent with the potential to cause pulmonary toxicity, most commonly in the form of diffuse alveolar damage. Cyclophosphamide-induced pulmonary toxicity is extremely rare and often difficult to recognize because of presence of confounding factors, including use of other cytotoxic drugs, radiation pneumonitis, oxygen toxicity, pulmonary infections, and malig...

Mice challenged intranasally with Naegleria fowleri died of primary amoebic meningoencephalitis. Mice given 30 mg of cyclophosphamide per kg of body weight daily for 10 days starting 2 days before challenge were protected. Neither cyclophosphamide nor serum from cyclophosphamide-treated mice inhibited N. fowleri in vitro. A metabolic product of cyclophosphamide, acrolein, inhibited growth and e...

INTRODUCTION Cyclophosphamide is commonly used as an important component in conditioning prior to hematopoietic stem cell transplantation, a curative treatment for several hematological diseases. Cyclophosphamide is a prodrug activated mainly by cytochrome P450 2B6 (CYP2B6) in the liver. A high degree of inter- and intra-individual variation in cyclophosphamide kinetics has been reported in sev...

abstract background: chemotherapy- induced nausea and vomiting (cinv) occur frequently causing problems with an unacceptably high incidence that significantly affect patients' daily functioning and health-related quality of life. the present study was aimed to compare acute cinv for granisetron as 5-ht3 receptor antagonist and metoclopramide in the patients receiving chemotherapeutic regimens i...

objective(s):cyclophosphamide (cp) toxicity on testis was hampered by squid ink polysaccharide (sip) via restoration of antioxidant ability in our previous investigations. this study investigated roles of nrf2/are signal pathway in testis of treated mice. materials and methods: male kunming mice were employed to undergo treatment with sip and/or cp. protein levels of nrf2, keap-1, histone deace...

Spermatogenesis is sensitive to the chemotherapeutic drug cyclophosphamide, which decreases the patients' sperm count. Since the recovery of fertility is dependent on regeneration from stem cells, in the present study we evaluated the ability of cyclophosphamide-exposed stem spermatogonia from mice to regenerate spermatogenesis in situ and after transplantation. When seven doses of cyclophospha...

Autoimmune responses were assayed in 80 cyclophosphamide-treated and control NZB/NZW mice over a period of 1 year. Fluctuation between positive and negative immunofluorescent heterogeneous ANA tests and daily alterations of ANA titers were detected in young mice of both sexes. Although high-dose cyclophosphamide therapy (8 mg/kg/day) failed to prevent the spontaneous appearance of ANA, titered ...
