Abstract
Background: Acetylcholinesterase inhibitors (AChEIs) are the treatment of choice for patients with Alzheimer’s disease (AD). However, their efficacy is moderate and differs from patient to patient. Recent studies suggest that the Q192R variant of the paraoxonase 1 gene (PON1) might affect individual susceptibility to these drugs. Methods: We investigated the influence of 3 single nucleotide polymorphisms (SNPs) in PON1 (rs 662, rs 854560, rs 705381) and the APOE common polymorphism in 101 Polish patients with late-onset AD in response to treatment with AChEIs. Results: No significant differences were observed between carriers and non-carriers of the PON1 SNPs or the APOE common polymorphism in terms of treatment response. These results did not change after stratification of APOE status. Conclusion: Our results suggest that both the investigated PON1 and APOE common SNPs do not influence treatment response to AChEIs in patients with AD.
