There are two types of membership, full and associate. Please see below for full details. Currently there are 57 full members and 34 associate members of the consortium. These include almost all the European Centres offering PGD/PGS and those of many other countries including Australia, USA, South Africa, Thailand, UAE, Japan, Brazil, Korea, Taiwan, Argentina, and Israel.
ESHRE has employed a scientific officer, Veerle Goossens, to deal with many of the consortium tasks. Please email Veerle.Goossens@eshre.com with any inquiries.
Our main task in the last 12 years has been to collect comprehensive data on PGD and PGS cycles. We have published 8 papers summarising the collected data (see the consortium publication link for the pdfs of these papers). A summary of the data is presented at ESHRE each year and published in Human Reproduction. We use a special filemaker Pro data base to collect data.
We have produced guidelines on PGD/PGS (see consortium publication link for pdf of this paper). These are currently being updated.
We feel it is important to have regular communication with registered centres. We do this via the newsletter, web site and meetings.
We send out regular consortium newsletters to any members of staff at registered clinics.
We are continually updating our web site. All training courses, meetings, newsletters and pdfs of our papers are listed on the web site.
We hold closed annual meetings (only members of registered centres can attend) on the Saturday before the ESHRE annual meeting to discuss the data and any other issues involving PGD/PGS.
We hold closed (only members of registered centres can attend) and open training courses. The next workshop with be a post congress course on ‘The use of arrays in PGD’ and will be held on Thursday 2nd July after the main ESHRE meeting in Amsterdam, 2009.
Accreditation
This is being chaired by Katerina Vesela. Accreditation is very important for diagnostic labs (and obligatory in some countries) and ideally all consortium members should be accredited. There is no doubt that this will be necessary in every country in time, but some countries do not have accreditation. We ran a very successful course on Quality Management and Accreditation process in PGD clinics and laboratories in Brno, Czech Republic last year and will be holding the same congress in London in 2010. The steering committee is currently writing a guide to accrediting a PGD lab.
Misdiagnosis
Joanne Traeger-Synodinos is chairing this working group. A paper on the causes of misdiagnosis is in press in Human Reproduction and will be available to download from the web site as soon as it has been published. The group are looking at confirmation of the diagnosis in untransferred embryos.
Guidelines
Gary Harton is running the guidelines working group so that we can update the guidelines we published in 2004. ESHRE have produced guidelines for writing guidelines.
Database
Celine Moutou is chairing the database working group. The database group is working on the results of pregnancies and babies. We plan to simplify the tables in data X and further papers. This will not change the way data are collected.
A new database is in preparation for the outcome of transfer of thawed embryos. This will only consider embryos which were frozen after biopsy and PGD.
The work of this working group has finished. ESHRE have set up a task force on PGS to try and set up a multi centre randomised control trial for PGS using arrays on polar bodies. A pilot study is being set up to determine the feasibility of this study.
After submitting data, full members are sent an annual certificate to show they are Consortium members for that year.
There are two parts to this study. A retrospective study is underway to follow up PGD babies and information will be available in Amsterdam. In the future we hope to set up a prospective study.
In 2008 we set up EQA for FISH and PCR.
FISH EQA
Twenty five centres took part in the pilot which was organised by Ros Hastings, UKNEQAS/CEQA (UK National External Quality Assessment Scheme/Cytogenetics European Quality Assessment), Joyce Harper, Alan Thornhill and Sjoerd Repping. The pilot was in two parts. Part one involved assessing two sets of images (PGD and PGS) via the web and participating centres had to score the images. Part two involved submitting a report for one previously reported PGD or PGS case. At the moment it is envisaged that participating centres do the EQA annually.
Members of the EQA for FISH PGD working group and assessors:
Ros Hastings, Joyce Harper, Alan Thornhill, Edith Coonen, Paul Scriven
PCR EQA
In collaboration with UK NEQAS (UK National External Quality Assessment Scheme)
The planned scheme will rely on sending ‘parental’ DNA samples and single cells from commercially available cell lines to participating labs to carry out tests for the diagnosis of cystic fibrosis and later for other disorders. The pilot will run in 2009. DNA from ‘parental’ and ‘affected relative’ cell lines will be sent to participating labs, participating labs will return a PGD feasibility report for the ‘family’, and then single lymphocytes from ‘offspring’ cell lines will be sent to participating labs who have a protocol that can be applied to the ‘family’.
