Management of Graves' Disease

Cheetham Tim , Lane Laura , Wood Claire

Managing Graves' disease (GD) should be simple. Stop the immune system from targeting the TSH receptor and the disease is cured. Unfortunately this is not yet feasible in most young people and GD is not a trivial condition for those affected. There are significant advantages and disadvantages of all current treatments with no easy way forwards for many and the family's decisions will reflect their perceptions of medical, radiation and surgical risk. The fact that two o...

Final Height is Negatively Related to Disease Burden in Mitochondrial Disease

Boal Rachel , Ng Yi Shiau , McFarland Robert , Cheetham Tim

Context: Abnormal growth and short stature are observed in patients with mitochondrial disease but it is unclear whether there is a relationship between growth, stature and muscle phenotype.Objectives: To examine growth and final height in patients with genetically confirmed mitochondrial disease, to describe growth patterns in the principle underlying genetic subgroups and to establish whether stature is related to disease severity.<p class="abstext...

Atypical Presentation of Six Patients with Mutations in the Side Chain Cleavage Enzyme CYP11A1

Chan Li , Huebner Angela , Spoudeas Helen , Cheetham Tim , Metherell Louise

Background: Mutations in the side chain cleavage enzyme, (CYP11A1) cause congenital adrenal insufficiency, with complete or partial 46XY sex reversal. The disorder manifests with adrenal and gonadal insufficiencies along with derangements of the renin/angiotensin system.Objective and hypotheses: To obtain a genetic diagnosis in six patients with adrenal insufficiency of unknown aetiology. Patients 1 and 2 are sisters with ACTH resistance, having...

Is testosterone supplementation required after induction of puberty in Duchenne muscular dystrophy? A follow-up study

Wood Claire , Mitchell Rod , Guglieri Michela , Straub Volker , Cheetham Tim

Introduction: Pharmacological doses of glucocorticoids (GC) reduce inflammation and preserve muscle function in boys with Duchenne muscular dystrophy (DMD) but cause almost universal pubertal delay. Long term consequences of GC on androgen status in young men who have received testosterone for pubertal induction remain unknown.Objective: To determine the longer-term outcome after a 2-year pubertal induction regimen using...

Randomised Trial of Block and Replace Versus Dose Titration Antithyroid Drug Treatment in Children and Adolescents with Thyrotoxicosis

Wood Claire , Cole Michael , Donaldson Malcolm , Dunger David , Matthews John , Pearce Simon , Cheetham Tim

Background: First line treatment for thyrotoxicosis is thionamide (TA) antithyroid drug therapy. The TA used is usually Carbimazole in the UK. TA can be administered in a relatively large 'blocking' dose that prevents endogenous thyroid hormone synthesis, requiring thyroid hormone replacement (block and replace or BR), or in a smaller dose that renders the patient euthyroid (dose titration or DT). The American Thyroid Association (ATA) recommends DT be...

Initial response to thionamide medication in young people with newly diagnosed thyrotoxicosis

Wood Claire , Morrison Niamh , Cole Michael , Donaldson Malcolm , Dunger David , Wood Ruth , Pearce Simon , Cheetham Tim

Methods: Patients commenced 0.75mg/kg carbimazole (CBZ) daily with randomisation to either BR or DT. We examined baseline patient characteristics, CBZ dose, time to serum TSH/FT4 normalisation and BMI Z-score. Results: There were data available from 80 patients (baseline) and 78 patients (61 female) at 6 months. Mean CBZ dose was 0.9 mg/kg/day (BR) and 0.5 mg/kg/day (DT). There was no difference in the time taken for...

Objective: Remission rates in young people with GravesÂ’ hyperthyroidism are 25% or less after a 2-yr course of thionamide antithyroid drug (ATD). Immunomodulatory agents could potentially improve outcome by facilitating immune tolerance. We wanted to explore whether rituximab, a B lymphocyte depleting agent, would increase remission rates when administered with a short course of ATD.Design: This was an investigator-...

NMDA (N-Methyl-D-aspartic acid) receptors have been shown to control the timing of sexual maturation in laboratory animals. Therefore, variants in genes impacting NMDA receptor signaling might be predicted to affect human puberty. We studied an extended family with extremely delayed puberty (menarche at 16.5 - 18 years for female family members and pubertal onset at 16 years for male family members). Exome sequencing revealed a rare missense variant (F900V) in DLG2, w...

Introduction: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires appropriate diagnosis and treatment. The most common cause of PAI is congenital adrenal hyperplasia (CAH), but other well-established aetiologies include metabolic and autoimmune disorders, and physical damage. Mutations in more than 30 genes have now been associated with PAI, with considerable biochemical and phenotypic overlap. It is therefore importan...
