Journal ArticleDOI
Loss of Infliximab Into Feces Is Associated With Lack of Response to Therapy in Patients With Severe Ulcerative Colitis
Johannan F. Brandse,Gijs R. van den Brink,Manon E. Wildenberg,Desiree van der Kleij,Theo Rispens,Jeroen M. Jansen,Ron A. A. Mathôt,Cyriel Y. Ponsioen,Mark Löwenberg,Geert R. D'Haens +9 more
TL;DR: High fecal concentrations of infliximab in the first days after therapy begins are associated with primary nonresponse, and additional studies are needed to determine how therapeutic antibodies are lost through the intestinal mucosa and how this process affects treatment response.
Journal ArticleDOI
Metformin in patients with advanced pancreatic cancer: a double-blind, randomised, placebo-controlled phase 2 trial
Sil Kordes,Michael Pollak,Aeilko H. Zwinderman,Ron A. A. Mathôt,Mariëtte J. Weterman,Aart Beeker,Cornelis J. A. Punt,Dick J. Richel,Johanna W. Wilmink +8 more
TL;DR: Addition of a conventional anti-diabetic dose of metformin does not improve outcome in patients with advanced pancreatic cancer treated with gemcitabine and erlotinib and future research should focus on patients with hyperinsulinaemia and patients with tumours showing markers of sensitivity to energetic stress.
Journal ArticleDOI
Cyclosporine interacts with mycophenolic acid by inhibiting the multidrug resistance-associated protein 2.
Dennis A. Hesselink,Reinier M. van Hest,Ron A. A. Mathôt,Fred Bonthuis,Willem Weimar,Ron W. F. de Bruin,Teun van Gelder +6 more
TL;DR: It is concluded that the pharmacokinetics of MMF are comparable in Mrp2‐deficient rats receiving either CsA or Tac as co‐medication, and this finding suggests thatCsA‐mediated inhibition of the biliary excretion of MPAG by theMrp2 transporter is the mechanism responsible for the interaction between Cs a and MMF.
Journal ArticleDOI
High within-patient variability in the clearance of tacrolimus is a risk factor for poor long-term outcome after kidney transplantation
Lennaert C. P. Borra,Joke I. Roodnat,Judith A. Kal,Ron A. A. Mathôt,Willem Weimar,Teun van Gelder +5 more
TL;DR: This study shows a significant relationship between the high within-patient variability in the clearance of tacrolimus, but not for MPA, and long-term graft failure.
Journal ArticleDOI
Explaining Variability in Mycophenolic Acid Exposure to Optimize Mycophenolate Mofetil Dosing: A Population Pharmacokinetic Meta-Analysis of Mycophenolic Acid in Renal Transplant Recipients
Reinier M. van Hest,Ron A. A. Mathôt,Mark D. Pescovitz,Robert D. Gordon,Richard D. Mamelok,Teun van Gelder +5 more
TL;DR: Exposure to total MPA, as determined by MPA clearance, significantly increased with increasing renal function, albumin level, and hemoglobin as well as decreasing cyclosporine predose level, which provides an indication for therapeutic drug monitoring as MPA exposure may be altered.
