34 year male brought in by ambulance feeling unwell. He had had a recent history (of about 48hrs) suggestive of upper respiratory tract infection (URTI) – runny nose, productive cough, sore throat etc. However, in the last 12 hours or so she had started to feel much more unwell. He felt more washed out and lightheaded, developed nausea and had vomited once or twice. He also felt that there was a slight increase in the cough.

|Left lower zone pneumonia||Crackles LEFT base
productive cough and SOB
recent URTI type infection
Bloods suggestive: raised WCC and CRP
|Viral infection||Coryzal symptoms – lethargy, fever, sore throat, runny nose etc
intermittently productive cough
Unlikely to cause patient to be quite so unwell
|Sepsis||Ticked loads of boxes for sepsis:
Mildly raised respiratory rate
Low blood pressure
Potential source: pneumonia
|Adrenal insufficiency (secondary)||On longterm steroids
Ticked loads of boxes for this:
Mild metabolic acidosis
Venous blood gas:
pH 7.30 – mild metabolic acidosis
Slightly abnormal electrolytes.
Chest x-ray: slight increased lung markings LEFT base
Bloods – Wcc 13 (neutrophils 10, lymphocytes 8)
Creat and Urea normal
ECG: Sinus tachycardia rate 120bpm
Diagnosis: Adrenal crisis
Treated for chest sepsis initially. Followed sepsis assessment and management bundles which included:
The patient then was then treated for adrenal crisis secondary to long term corticosteroid use and new illness. It turned out he had been on budesonide for her Crohn’s for the last 3 months. He was given: Hydrocortisone 200mg IV.
The adrenal glands are important endocrine glands they produce cortisol which is released during times of stress to help with immune function, vascular tone and metabolism.
Cortisol release is controlled by the hypothalmic-pituitary-adrenal axis and any disruption to this can lead to adrenal insufficiency.
Causes can be either primary or secondary:
Primary causes are due to direct disease of the adrenals and the most common cause is Addison’s but can also result from trauma, drugs, infections, infiltrative disorders, and genetic disease.
Secondary causes occurs with sudden termination of prolonged glucocorticoid therapy and pituitary disease including brain tumours, medication, necrosis or bleeding, infectious disease, and infiltrative disorders.
When the body is under stress the low cortisol levels are quickly depleted, and the body is unable to mount an appropriate response resulting in an adrenal crisis. The stress can be caused by infection, surgery, trauma, and has even been shown to occur after strenuous exercise or emotional stress
