Association between SLC19A1 gene polymorphism and high dose methotrexate toxicity in childhood acute lymphoblastic leukaemia and non Hodgkin malignant lymphoma: introducing a haplotype based approach

haplotype for SLC19A1 rs7499, rs1051266, rs2838956 and rs3788200 with MTX gastrointestinal toxicity was established. 38 The results of the haplotype based analysis indicate, that other polymorphisms that are in linkage disequilibrium with rs1051266 and rs1131596, may impact the functioning of SLC19A1 via, for example, alterations in SLC19A1 splicing. 39 , 40 As well, other genes coding for proteins that are involved in the transport and metabolism of MTX can also impact pharmacokinetics and the occurrence of MTX-induced AE, such as SLCO1B1 SNPs that are

However, it should be remembered that rivaroxaban is contraindicated in patients with advanced cirrhosis (Child class B and C), after a pharmacokinetic study showed increased rivaroxaban concentrations in patients with moderate hepatic impairment;[ 32 , 33 ] while apixaban has the highest percentage of hepatic metabolism (up to 73%) and therefore should be used with caution in patients with mild or moderate liver impairment (Child class A and B), it is not recommended in patients with severe

Aspirin resistance in coronary heart disease: Current understandings and strategies

the definition, mechanism, clinical impacts, detection, and intervention of aspirin resistance. Definition of Aspirin Resistance The concept of aspirin therapy response variability is mainly based on specific pathophysiological mechanisms, pharmacokinetics, and/ or pharmacodynamics by which aspirin works. aspirin resistance may be simply one of potential causes leading to interindividual variability in the response to aspirin. [ 1 ] In 2009, the Working Group on Thrombosis of the European Society of Cardiology released a position paper on interindividual

Prognostic role of diffusion weighted and dynamic contrast-enhanced MRI in loco-regionally advanced head and neck cancer treated with concomitant chemoradiotherapy

, motion correction algorithm was applied that allowed for pairwise in-plane (acquisition plane) rigid co-registration of all raw perfusion images of a given slice location with well-chosen reference image over time. Quantitative DCE-MRI parameters were volume transfer constant (K trans ), extracellular extravascular volume fraction (v e ) and plasma volume fraction (V p ). The pharmacokinetic modelling was done on a pixel-by-pixel basis using the extended Tofts model - a two compartment model, which is suitable for any freely diffusible tracer. The equation modelling

[ 5 ] However, the evidence is scarce for other factors, particularly the impact biotype, [ 6 ] smoking, [ 7 ] diabetes mellitus (DM), [ 8 ] and previous treatment failure. In particular, it is unknown whether the body mass index (BMI) influences in a clinically significant way the pharmacokinetics and/or pharmacodynamics of the drugs involved in eradication (in particular, the proton pump inhibitors and antibiotics). Furthermore, to date, studies are in most cases controlled in relation to the
