CAH Adult Study Executive
Background
Congenital Adrenal Hyperplasia (CAH), one of the most common inherited diseases, affects 1:14,200 live births. It is the result of a genetic defect in one of the enzymes (typically 21-hydroxylase) required for cortisol biosynthesis, leading to reduced levels of cortisol and aldosterone, increased ACTH concentrations and consequently increased adrenal androgen production.
An audit of adults with CAH in the UK conducted by the Society for Endocrinology revealed a lack of a consensus on the best treatment for adults with CAH (Ross RJM, UK audit of Adult Congenital Adrenal Hyperplasia Care. J. Endocrinol 164 suppl: S38). CAH has therefore been identified as an area that requires further research into the day-to-day management of adults with CAH.
The Society for Endocrinology, with a grant from the Clinical Endocrinology Trust, set up CaHASE in 2003 under the chairmanship of Prof Richard JM Ross (Sheffield). It specifically looks at congenital adrenal hyperplasia in adulthood. Eighteen specialist endocrinology centres around the UK are currently collaborating in CaHASE, a multi-centre prospective research study. By working together the 18 centres aim to study a large number of patients to obtain much needed information on the effect of CAH in adults.
Aim
- To identify the medical, psychological and physical problems experienced
by patients with CAH.
- To identify areas of patient care where there
is currently consensus or disagreement.
- To identify gaps in current
knowledge where further research is needed.
- To publish a peer-reviewed
paper containing a comprehensive review of the points above.
Protocol
Patients
The inclusion criteria for the study are adults (age range
18-65) with all types of CAH (classical/non-classical, salt-wasting/non-salt-wasting
and all genotypes). Patients are approached by their clinician
at their routine clinic appointment to see if they would like to take
part in the study.
Methods
A case record form and self-administered quality of life questionnaires
are completed for each patient with CAH who consents to take
part in the study. Blood samples for genetic analysis and hormone profile
are also taken. In order to obtain information on the causes
of morbidity in patients with CAH, participants in the study are flagged
with the Office of National Statistics.
Ethics
The study has MREC approval (MREC 04/07/013) and is conducted
in accordance with UK legislation on data protection, ethics and
written informed patient consent.
Governance
CaHASE is a collaborative research project overseen by a Project Board
made up of representatives from the participating centres under the
auspices of the Clinical Committee of the Society for Endocrinology.
The board is chaired by Professor R J M Ross. The board is reviewed on
an annual basis by the Clinical Committee.
The Project Board meet at least once a year and is responsible
for setting the project targets and monitoring outcomes. It is responsible
for raising any necessary funds and for monitoring and approving expenditure.
Ownership of data
The data will be owned by the Society for Endocrinology.
Support
The Society is grateful to the Clinical Endocrinology Trust for their
continued financial support.
