Apologies if this is a duplicate post and if its rumor. I honestly cant tell its in German. I just came across this blog looks like Dec 2nd, 14:52, commenting on whether the huge German hospital Charit in Berlin would be recommending the XMRV test. The German version is here: http://www.symptome.ch/vbboard/chro...-charite-keine-empfehlung-fuer-xmrv-test.html And the translation by Google is here: http://translate.google.ca/translat...en-US:official&hs=Gwl&tbo=p&num=100&tbs=qdr:d "Charite: No recommendation for a XMRV test Originally Posted by Charite XMRV beim CFS XMRV in CFS Kategorie: News - Patient Care Recently, working from the National Institutes of Health, and Whittemore Peterson Institute, a new retrovirus XMRV as a trigger for CFS patients described in the U.S.. From the Robert Koch Institute, have now also German patients with CFS on XMRV investigated. The preliminary results are different than in the U.S., as in the previously studied XMRV patients can be demonstrated only rarely. Further investigation is underway in cooperation with the U.S. group. At present we can therefore not recommended to be tested for XMRV. But the study from the USA could not yet demonstrated that CFS is caused by XMRV there, because so far it only shows that this virus in patients with CFS is frequently demonstrated. Another respondent: It was expected! In a large study XMRV in cancer, which has recently (October 2009) was published, the virus hardly (or not) has been demonstrated. (NOTE: I think they're talking about the German prostate ca research here) In the German study, scientists at the Robert Koch Institute and the Charite Hospital (Urology) were involved. Now that short term CFS patients in our hospital (Medical Immunology) have been investigated, is all right, but also points to the current problems. Since the virus was discovered in 2006 in the U.S., studies in several countries have come to different conclusions. And: In the studies of prostate cancer / XMRV different tests have been used.[/B] The main problem: There is currently no validated test. The tests in the laboratory, the need to cooperate with the WPI, are still under consideration. In plain language: It must be present as the first validated tests before they can study results are comparable and verifiable results. (MY TRANSLATION: They have to first have a validated XMRV test, before a study can compare apples & apples). " FYI - about Charit From Wikipedia: http://en.wikipedia.org/wiki/Charité The Charit - Universittsmedizin Berlin is the medical school for both the Humboldt University and the Free University of Berlin. After the merger with their fourth campus in 2003, the Charit is one of the largest university hospitals in Europe If I understand correctly, the key message: Were these comparable studies i.e. same definition of ME/CFS patients (eg. Canadian/Fukuda CFS criteria), same tests (i.e. same XMRV assays)? If not, its apples and oranges. Not only does Charit seem to "get" this, in fact they come right out and say "different tests were used" for the prostate XMRV research. It sounds as though they are collaborating with WPI (?and the Cleveland Clinic?) on the CFS work. This may be the optimist in me, but it sounds as though the initial sparse German finding of XMRV in their CFS patients are reinforcing the need to cooperate with the WPI. Good scientists want "clean" answers, and the Charit seem to care about eliminating scientific noise. One other note - haven't a lot of the blogs talked about a 6 month timeframe for a "validated XMRV test? Or maybe the Germans are sufficiently impressed with WPI's work to just hop on their wagon and use WPI's XMRV tests. Time will tell, but at least Charit appears to be quite meticulous in the science they use to declare or refute an XMRV/ME/CFS link. A housekeeping issue: It's getting a little crowded as we wait for news of replication of WPI's XMRV results. Given that there are over 200 posts and 12,000 views, might I suggest that we have separate threads for discussion of "News of replication of WPI XMRV study?": 1) Discussion of replication of... 2) German Charit XMRV results 3) UK Kerr et al XMRV results 4) ...? And/or a "Sticky" posting published "Actual XMRVreplication results" when they are available?
