Hypothyroidism causes
Primary:
- Hashimoto’s (autoimmune) - most common
- Iodine deficiency
- Riedel’s thyroiditis (fibrosis of gland) (reduced TRH release)
Secondary:
- Reduced TSH release from pituitary
Hyperthyroidism DDx
Primary hyperthyroidism
- Graves disease = most common
- Toxic adenoma
- Toxic multinodular goitre
- De Quervains thyroiditis
- Amiodarone thyrotoxicosis
- Exogenous levothyroxine
Secondary hyperthyroidism (excess TSH release)
De Quervains thyroiditis disease course
hyper -> eu -> hypothyroid -> euthyroid
PAINFUL GOITRE
Management of hypothyroidism
Levothyroxine
Complications of hypothyroidism
Most concerning: myxoedema coma
(Hypothermia, bradycardia, hypoglycaemia, reduced GCS)
Metabolic:
- Hypercholesterolaemia
- Weight gain
Cardiac:
- Ischaemic heart disease
- Bradycardia
- Heart failure
Neuro
- Depression
- Peripheral neuropathy
- Cerebellar syndrome
Investigations in thyroid disease
- TFTs
- Anti-TSH receptor antibodies (Graves)
- Anti-TPO antibodies (Hashimotos)
- Screen for other autoimmune disease e.g. coeliac, hypoparathyroidism, etc
US neck - assess goitre
Consider iodine uptake scan
Iodine uptake scan - interpretation of results
Diffuse increased uptake = Graves
Hot spots of increased uptake = toxic multinodular goitre
Single hot spot = toxic adenoma
Diffuse reduced uptake = de Quervains
Management of Graves
Symptomatic: Propranolol
For the thyroid:
1) Carbimazole - risk of agranulocytosis.
- can ‘block and replace’
2) Propylthiouracil - better in Pregnancy and Pancreatitis
If any agranulocytosis develops…
STOP THYROID DRUGS
Offer radioiodine treatment
Management of toxic multinodular goitre hyperthyroidism
First line = radioiodine
Second line:
- Anti-thyroid drugs (carbimazole, propylthiouracil)
- Offer thyroidectomy
Management of toxic adenoma hyperthyroidism
First line = hemithyroidectomy or radioiodine
Cushing’s syndrome causes
Pituitary adenoma -> excess release of ACTH (Cushing’s disease)
Adrenal adenoma -> excess release of cortisol
Ectopic ACTH secretion e.g. lung Ca
Exogenous steroids
Cushing’s disease examination
General inspection:
- Central adiposity
- Hirsutism
- Fat re-distribution: Central adiposity, Moon face, bufallo hump
- Striae
- Buffalo hump
- Check for evidence of diabetes (CBG)
Check cardiac, respiratory and abdominal systems
Proximal myopathy
Blood pressure
Cushing’s investigations
Low dose dexamethasone suppression test - see if cortisol remains elevated
High dose dexamethasone suppression test
- Dexamethasone suppresses ACTH production, not cortisol
- Cushing’s syndrome: Low ACTH and low cortisol
- Adrenal adenoma: Low ACTH and high cortisol
- Ectopic tumour: High ACTH and high cortisol
Also
- HbA1c, renal profile
- Pituitary profile
- Blood gas would show hypokalaemic metabolic alkalosis
- MRI pituitary +/- CT chest (Ectopic) / abdomen (adrenal adenoma)
Cushing’s management
Disease: transsphenoidal resection of pituitary tumour
Syndrome: Treat underlying cause
- Wean exogenous steroids
- Adrenal tumour resection
- Ectopic tumour resection
- meds include metyrapone or ketoconazole to reduce cortisol production
Management of complications:
Hypertension
Hyperglycaemia
Osteoporosis definition
