Pharmacovigilance study and genetic target prediction analysis of FDA adverse event reports (FAERS) for drug-induced...

Drug-induced sinusitis has been widely reported as an adverse drug reaction in recent years, yet the pharmacogenetic mechanisms and risk factors associated with sinusitis remain elusive.

We aimed to identify the major drugs reported in the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) in relation to sinusitis and to analyze their pharmacogenetic mechanisms through drug target analysis.

We conducted a review of the publicly available FAERS database from 2004 to the third quarter of 2023. We extracted genetic tools corresponding to each drug, utilized colocalization analysis, Mendelian randomization (MR) analysis, and cross-tissue drug target analysis to predict the impact of drug targets on sinusitis.

Following the validation of drug-related risks, a total of 13 medications were ultimately identified, including TNF inhibitors: pomalidomide (ROR: 14.77), certolizumab pegol(ROR: 8.21), etanercept (ROR: 7.961), lenalidomide (ROR: 6.998), adalimumab (ROR: 6.677), infliximab (ROR: 3.939); C4B-targeted drugs: human immunoglobulin G (ROR:3.846) and other risk drugs were commonly reported. Co-localization analysis and MR analysis suggests associations between TNF, C4B, and LTA and sinusitis.

We demonstrated the risk of sinusitis associated with 13 drugs, including pomalidomide, and the impact of TNF and C4B drugs on sinusitis, which provides guidance for the use of related drugs and the prevention of sinusitis.
