Development and validation of a sensitive and specific hplc assay of cladribine for pharmacokinetics
Purpose: To develop and validate a sensitive and specific HPLC assay for cladribine (CdA) in plasma for pharmacokinetic studies in rats. Methods: CdA and the internal standard AZT were purchased from Sigma-Aldrich Chem. The HPLC system consisted of a Shimadzu LC-9A pump, a 3 μm, 250 x 2.0 mm I.D. high speed C18 column (Jupiter), preceded by a 5 μm 4 x 4 mm I.D. C18 guard column (Licrocart), an ...
A mycoplasma-encoded purine nucleoside phosphorylase (designated PNPHyor) has been cloned and characterized for the first time. Efficient phosphorolysis of natural 6-oxopurine and 6-aminopurine nucleosides was observed, with adenosine the preferred natural substrate (Km = 61 µM). Several cytostatic purine nucleoside analogs proved to be susceptible to PNPHyor-mediated phosphorolysis, and a mark...
Mast cell leukemia is a rare variant of advanced systemic mastocytosis characterized by at least 20% of mast cells in a bone marrow smear. We evaluated clinical and molecular characteristics of 28 patients with (n=20, 71%) or without an associated hematologic neoplasm. De novo mast cell leukemia was diagnosed in 16 of 28 (57%) patients and secondary mast cell leukemia evolving from other advanc...
PURPOSE The aims of this study were to characterize the concentration-time course of cladribine (CdA) and its main metabolite 2-chloroadenine (CAde), estimate interindividual variability in pharmacokinetics (PK), and identify covariates explaining variability in the PK of CdA. METHODS This population PK analysis was based on the combined dataset from four clinical studies in patients with mul...
AIM To evaluate cladribine [2-chlorodeoxyadenosine (2-CdA)] therapy in refractory celiac disease (RCD) II. METHODS An open-label cohort-study of RCD II patients treated with 2-CdA was performed between 2000 and 2010. Survival rate, enteropathy associated T-cell lymphoma (EATL) occurrence, clinical course, and histological and immunological response rates were evaluated. RESULTS Overall, 32 ...
Modern methods of cancer treatment like chemotherapy are effective in eradicating cancer cells; however, the following immunosuppression and cellular damage that occur are often strenuous on the human body. This study sought to design a novel therapeutic treatment model that could not only reduce adverse effects experienced by patients, but also be applied to multiple forms of cancer and their ...
