timeline of key milestones
2017
2018
2020
2022
2017
Validation study, dnDSA incidence
  • PIRCHE-II score strong predictor for dnDSA post kidney transplantation
  • PIRCHE-II independent from antigen mismatch and HLAMatchmaker
  • supports that T cell epitopes and B cell eplets are both independent yet complementary indicators for risk

2018
PIRCHE-II impact in graft survival
  • PIRCHE-II may impact graft survival after kidney transplantation
  • Both, early and late effects on graft survival in recipients receiving their first transplant

2020
Need for B and T cell analysis
  • Pirche scores significantly correlated with de novo class II DSA production.
  • The study concludes that the analysis of T cell and B cell epitopes can provide beneficial information on the design of individualized immunosuppression regimens for prevention of de novo DSA production after kidney transplantation.

2022
Biopsy + Rejection
  • PIRCHE-II scores higher in patients developing TCMR and patients with ongoing TCMR
  • PIRCHE-II scores elevated in ABMR patients who show increased microvascular inflammation

Webinar 2018 E1: Introduction and Overview

DESCRIPTION

In the first Webinar of our series, we give an overview about the PIRCHE matching technology and its application in stem cell transplantation and solid organ transplantation. We pinpoint the most important publications and how the algorithm is translated into a useable toolsuite. In the second half, we dive into the web app giving you an overview of how to use the service.

Webinar 2020-05: “Epitope Matching: There is no Excuse” (In Collaboration with Omixon)

DESCRIPTION

In this presentation, Matthias Niemann, Technical Director of PIRCHE, explains the ways of HLA allorecognition and shows the differences between the known HLA epitope matching methods. He summarizes the clinical findings around HLA epitope mismatches and finally clears up common misunderstandings about epitope matching.

Special thanks to Omixon for inviting us to your webinar series.

Webinar 2021-02: “PIRCHE Epitope Matching in Kidney Transplantation: A Case Study ” (In Collaboration with GenDx)

DESCRIPTION

In this session, Eric Spierings, inventor of the PIRCHE concept, and Matthias Niemann, PIRCHE Director of Technology, introduce the epitope matching landscape, showing firstly how the PIRCHE algorithm integrates into the wider context of existing epitope matching models and secondly explaining what makes it different from other models with which you may or may not already be familiar.

To give you a practical insight into how PIRCHE matching is applied on a case by case basis in the solid organ transplantation setting, a case study is also presented to show how PIRCHE matching may be applied in kidney transplantation. The session is rounded out by presenting some recent insights into PIRCHE epitope matching.

Special thanks to GenDx for inviting us to your webinar series.
