Caroline Lucas, leader of Green Party and MP for Brighton Pavilion, tabled two written questions on the blood ban which is to be imposed on everyone in the UK who has ME/CFS from November 1.
In the first, she asked the Secretary of State for Health on what date his Department's decision that people with myalgic encephalomyelitis should not give blood was (a) made and (b) implemented.
In her written reply on 19 October 2010, Anne Milton (Parliamentary Under Secretary of State for Public Health) wrote:
The UK Blood Services decision to permanently exclude from blood donation anyone who reports that they have had Myalgic Encephalopathy/Chronic Fatigue Syndrome (ME/CFS) was made on 8 July 2010. The change to the donor selection guidelines will come into force on 1 November 2010.
This change is being made on the grounds of donor safety, as ME/CFS is a relapsing condition. It brings practice for ME/CFS into line with other relapsing conditions or neurological conditions of unknown origin.
The change is being made on the grounds of donor selection criteria by the UK Blood Services Standing Advisory Committee on the Care and Selection of Donors, and Joint Professional Advisory Committee.
In her second question, Caroline Lucas asked the Health Secretary whether – with reference to an answer given to the MP for Stroud on 27 January* whether (a) the UK Blood Services and Health Protection Agency study of the prevalence of a rodent virus linked to ME and (B) his Department's risk assessment in respect of the study had been completed; and if he will make a statement.
Anne Milton replied:
There has been a consistent failure of independent European and American studies to confirm the original American study that described the detection of xenotropic murine leukemia virus-related virus (XMRV), a virus related to rodent viruses, in patients with chronic fatigue syndrome, sometimes referred to as myalgic encephomyelitis.
An expert subgroup of National Expert Panel for New and Emerging Infections (NEPNEI) met in May 2010, to consider all available evidence about XMRV and conduct a risk assessment. The subgroup concluded that XMRV can infect humans but there is currently no evidence that it causes human disease and that on the evidence before the group, no public health action is required at this time. Since the subgroup meeting in May there has been no new scientific evidence that would change the conclusions of the subgroup but they are keeping it under review.
The Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO), on the basis of current evidence does not recommend further measures at present but wishes to continue to monitor the situation. The NHS Blood and Transplant and Health Protection Agency study group concur with the views expressed both by NEPNEI and SaBTO but also recognise the need for further research on the prevalence of XMRV in the United Kingdom.
In a recent unpublished pilot study conducted by the group a series of 540 randomly selected English blood donors were screened for XMRV and none were found to be infected.
