Background: Macrolides are widely used antibiotics, but adverse drug reactions (ADRs), particularly in genetically predisposed individuals, can compromise their safety. This study examines the impact of pharmacogenetic markers on macrolide safety in participants with bacterial complications of influenza.

Objective: To evaluate how polymorphisms in genes encoding transporter proteins (ABCB1) and enzymes (CYP3A4, CYP3A5) influence ADR risk during macrolide therapy.

Article Synopsis
  • Statins are key medications used to prevent cardiovascular disease by not only lowering lipids but also reducing inflammation, measured by C-reactive protein (CRP).
  • Two significant genetic loci linked to how individuals respond to statin treatment in terms of changes in CRP levels were identified: APOE and HNF1A, both of which are associated with various health conditions like coronary artery disease and diabetes.
  • Further analysis suggests that the APOE-E4 variant may influence the effectiveness of statins, hinting at its potential role in personalized healthcare for those with cardiovascular and related conditions.

The enzyme dihydropyrimidine dehydrogenase (DPD) is the primary catabolic pathway of fluoropyrimidines including 5 fluorouracil (5FU) and capecitabine. Cases of lethal toxicity have been reported in cancer patients with complete DPD deficiency receiving standard dose of 5FU or capecitabine. DPD is encoded by the pharmacogene DPYD in which more than 200 variants have been identified.

Use of a Personalized Clinical Decision Support System for Dosing in Psychopharmacotherapy in Patients with Alcoholic Hallucinosis Based on Pharmacogenomic Markers.

Introduction: Alcoholic hallucinosis (AH) is one of the severe complications of chronic alcoholism, characterized by psychotic symptoms such as auditory hallucinations and delusions. Haloperidol is widely used to treat AH; however, its therapy is often complicated by side effects. A personalized approach using pharmacogenetic testing (particularly the CYP2D6 polymorphism) allows individualization of haloperidol dosage, improving both safety and efficacy of therapy.
