Abstract

Gastrointestinal haemorrhages (GIHs) are one of the most frequent and severe adverse drugreactions. The idiosyncratic responses with respect to the haemorrhages observed inindividuals consuming acetylsalicylic acid (ASA) as an antiplatelet agent could be due to thepresence of genetic variants described in the genes that encoding enzyme targets involved inthe pharmacological and pharmacodynamic activity of AAS metabolismo: cyclooxygenase(cox)-1, Nitric oxide synthases (eNOS), cytochrome p450 (CYP2C9); p-glycoprotein(ABCB1) and Vitamin K epOxide Reductase Complex (VKORC1). The objective of thisstudy is to asses the risk of GIH by ASA consumption related to the presence of these geneticvariants. METHOD: An incident case-control study will be performed. Individuals (n=200)suffering ulcer perforation or upper gastrointestinal bleeding, diagnosed by endoscopy, willbe considered cases. 600 controls will be recruited from the preoperative unit to undergotrivial surgeries of painless processes. Both the cases and the controls will be extensivelyinterviewed, and ASA consumption and variables of control and adjustment will be evaluated.SNP genotyping will be identified by real-time polymerase chain reaction (PCR) with theTaqPath ProAmp assay (Applied Biosystems®). A pooled analysis will be performed with thedata of the previous study and with the current one, constructing mixed linear models todependent binomial-type variables. (AU)
