Published: in Frontiers in Immunology 2021; 5364.

Patients: 231

Highlights:

  • Analyzed 231 pregnancies as model system
  • 11 loci high-resolution typing of all individuals
  • Confirms PIRCHE presented by HLA-DRB1 along with HLA-DRB3/4/5, -DQ, and -DP are significant predictors for development of CSA
  • Combining multiple presenting loci in a single predictor improved the model only marginally
  • PIRCHE further improved through normalization by respective presenters’ binding promiscuity
