The proposal will undertake prospective multi-source surveillances through the
Surveillance Unit of Paediatrics and Child Health (the ‘British Paediatric
Surveillance Unit’), liaising with the National Creutzfeldt-Jakob Surveillance Unit
(CJDSU), for all cases of progressive intellectual and neurological deterioration
(PIND) occuring in children under the age of 16 in the United Kingdom. The
incidence of PIND and, as far as possible, its causes will be determined. Further
investigation will be encouraged on those cases without a readily identifiable cause to detect children suffering from any form of CJD, should they occur.
The programme will commence through the production of an initial surveillance
case definition for PIND by an Expert Neurological Advisory Group. This will be
circulated to all paediatricians via the Surveillance Unit of the Royal College of
Paediatrics and Child Health (the ‘British Paediatric Surveillance Unit’).
Paediatricians will make returns of cases and will be sent an “initial contact form”. Following this, if a reported case meets the surveillance case definition and does not have a confirmed or likely diagnosis, the case will be followed up by a telephone interview or visit from the research nurse to the clinician. The research paediatric neurologist may need to contact the local clinician to discuss
investigations of individual cases of PIND. Any cases identified as possible CJD
will be referred to the CJDSU, which will follow them up according to currently
agreed CJDSU protocols. The Expert Neurological Advisory Group will agree the
case definition and will meet quarterly to discuss all the notified cases of PIND and allocate them to appropriate diagnostic groups.
The surveillance will be overseen by a Steering Committee that includes the
participating institutes and representation from the Department of Health. This
Committee will also review overall progress and agree release of data.
The contract will run for 5 years but a review after 18 months will be held to give
an early warning of a need to extend the surveillance beyond this time. Annual
reports will be provided to the Department of Health.

Policy Relevance
By observing the epidemiology and causes of Progressive Intellectual and
Neurological Deterioration in Childhood (PIND), the proposal addresses three important issues for the Department of Health:
to determine whether CJD (either sporadic, new variant or other forms)exists in children in the UK
to improve diagnosis and management of CJD in children, should it occur, by heightening the awareness of doctors to these diseases and by using common protocols to detect them
to provide a mechanism to monitor CJD numbers in children and to determine risk factors which may lead to CJD
