ESID IEWP Report – November 2016
I write as the end of the year approaches to update you on the year to date and inform you of future events.
The annual Autumn meeting of IEWP was hosted by Victoria Bordon in Ghent, Belgium at the Het Pand old university buildings. Around 100 people attended, including participants from Australia, Malaysia, Hong Kong, Brazil, Canada and the USA. We covered topics ranging from a very lively, but interesting session on pharmacokinetics, a philosophical, yet practical discussion of the definition of Severe Combined Immunodeficiency in the era of newborn screening and modern genomics, a session on Chronic granulomatous disease and Wiskott Aldrich syndrome and a session on outcomes of HSCT for emerging diseases – the same session last year has resulted in two publications with a further two manuscripts submitted. The session on severe combined immunodeficiency was introduced by an excellent presentation on T cell exhaustion following HSCT – other presentations included longterm outcomes and gene therapy. Steve Holland from NIH, Bethesda gave the Keynote Lecture on Chronic Granulomatous Disease, with interesting insights into x-linked carriers, and potential implications for partial donor chimeras, or recipients of gene therapy.
The debate about the use of T cell depleted donors versus mis-matched unrelated donors, postponed from last year, gave rise to a lively discussion generating ideas for the development of new guidelines. The meeting concluded with a review of progress on current studies and some new proposals. The informal atmosphere of an IEWP meeting was maintained, with close friendships, and shared goals of developing new treatments to improve outcomes for our patients. The beautiful city of Ghent entertained us each evening including a memorable, though wet, boat trip, Belgian beer and chocolate.
Future meetings next year are:
- IEWP sessions during EBMT 43rd meeting of EBMT in Marseilles – the paediatric day with IEWP is on 28th March 2017
- IEWP Autumn meeting, Newcastle upon Tyne, 3-5 November 2017
