Is there evidence of vertical transmission of variant CJD?
OBJECTIVES: The possibility of vertical transmission of variant CJD (vCJD) has been raised, because of the widespread distribution of infectivity in vCJD and the demonstration that this condition can be transmitted through blood transfusion. The aim is to search for evidence of this type of transmission of vCJD. METHODS: A national surveillance system for CJD has been established in the UK since 1990. Through this register details were extracted of all children born to vCJD cases up to March 2009. This list was checked against the CJD register and cases identified through the UK study of progressive intellectual and neurological deterioration in children (PIND) to determine whether any of the children of vCJD cases had themselves developed a progressive neurological disorder or vCJD. RESULTS: 125 children have been born to parents with a diagnosis of vCJD. Nine of these children were born to females with vCJD who were symptomatic at conception, birth or within a year of clinical onset.
