Genetic variants in TNFα, NLRP3, MYD88, and FcRγ genes were associated with a response to TNFi, when assessing several inflammatory diseases together. Al-Sofi et al. conducted a systematic review and meta-analysis on single nucleotide polymorphism (SNP) genetic markers and their response to biologics in psoriasis, PsA, RA, IBD, and across all chronic inflammatory diseases together.

The authors reviewed drug survival of therapies across common inflammatory skin and joint conditions from national registries.  The findings highlighted that despite the overlapping pathogenesis of these conditions there was little similarity in drug survival. This reinforces the need for an individualised treatment approach consistent with the underlying disease, patient profile and treatment history.
