Pharmacogenetic algorithm for predicting daily dose of warfarin in Caucasian patients of Czech origin.

Objectives: Warfarin use is limited by a low therapeutic index and significant interindividual variability of the daily dose. The most important factor predicting daily warfarin dose is individual genotype, polymorphisms of genes (warfarin metabolism) and (sensitivity for warfarin). Algorithms using clinical and genetic variables could predict the daily dose before the initiation of therapy.

Warfarin loading dose guided by pharmacogenetics is effective and safe in cardioembolic stroke patients - a randomized, prospective study.

Warfarin treatment is commonly started with a fixed loading dose that might be associated with an increased risk of bleeding. An individual maintenance dose can then be estimated based on a pharmacogenetic algorithm. Starting treatment with the estimated dose implies a longer time to reach the therapeutic range.

Myxovirus Resistance Protein A mRNA Expression Kinetics in Multiple Sclerosis Patients Treated with IFNβ.

Introduction: Interferon-β (IFNß) is the first-line treatment for relapsing-remitting multiple sclerosis. Myxovirus resistance protein A (MxA) is a marker of IFNß bioactivity, which may be reduced by neutralizing antibodies (NAbs) against IFNß. The aim of the study was to analyze the kinetics of MxA mRNA expression during long-term IFNβ treatment and assess its predictive value.
