The Charles Dent Metabolic Unit (CDMU) is one of the largest and longest established services in the world for the treatment of adolescents and adults (aged 16 years and older) with inherited metabolic diseases, including, among others, phenylketonuria, homocystinuria, galactosemia, fatty acid oxidation defects, glycogen storage disorders, X-linked hypophosphatemia, peroxisomal and urea cycle defects.
Staff at the unit provide specialist medical, dietetic, psychological and nursing advice. We have a purpose-built metabolic diet kitchen to support treatment and education of patients.
The unit is also a designated NHS England highly specialised lysosomal storage disorder service and includes an infusion unit which provides the facilities needed for patients on enzyme replacement and other therapies. We see patients with a range of LSDs including Fabry disease, Pompe disease, Gaucher disease, Niemann-Pick diseases, mucolipidoses and the mucopolysaccharidoses.
The unit has a long history of involvement in research and clinical trials of new therapies for inherited disorders of metabolism. A link to current research is available here: http://www.bimdg.org.uk/site/research.asp.
We have strong links with our paediatric colleagues at Great Ormond Street Hospital, sharing laboratory facilities, teaching and training opportunities. We also attend regular joint clinics at Great Ormond Street Hospital to help support adolescents and young adults transferring from paediatric to adult medical services.
We also provide a specialist ketogenic diet therapy service for adults with epilepsy. The specialist ketogenic dietitian is a member of the Ketogenic Dietitians Research Network (KDRN) and runs group education sessions quarterly and provides specialist support for those wishing to undertake ketogenic diet therapy for management of their epilepsy.
Patients who require a hospital admission for investigations or to start treatment are admitted to a purpose built complex care ward, which is fully adapted to support all physical needs. For those with learning disabilities, every effort is made to ensure that an individual side-room is booked to allow a parent or carer to remain overnight.

Patient support is provided by two clinical nurse specialists, research nurses, a clinical psychologist, four metabolic dietitians, a dietetic assistant and administrative staff. Which team members are involved with each patient depends on diagnosis, type of treatment and patient need.
