Ian Lipkin note to Vincent Racaniello on the latest XMRV controversy: 6 May 2011

From Vincent Racaniello’s ‘Virology Blog’, 6 May 2011.

Late last year virologist Ian Lipkin was asked by National Institute of Allergy and Infectious Diseases head Anthony Fauci to coordinate a multi-center study of CFS patients. Newly drawn blood samples from 100 CFS patients and 100 healthy controls from around the US will be blinded and sent to three groups – FDA, CDC and the Whittemore Peterson Institute – and assayed for the presence of XMRV. After the recent publication by Ila Singh on XMRV in CFS patients, Dr. Lipkin sent me the following note:

Dear Vince-

We have a plethora of explanations for how CFS/XMRV/MLV studies could go awry. However, we don’t have evidence that they have. Absent an appropriately powered study representing blinded analyses by Mikovitz and Lo/Alter of samples from well characterized subjects using their reagents, protocols and people, all we have is more confusion.

I remain agnostic. We won’t have answers until the end of 2011.

The NIH will post something on our study today.

Ian
