IS IT THIS? - reference only, to read alongside your own examination
  SYMPTOMS - what the patient reports (5)
    - Low blood pressure, confusion, loss of appetite, vomiting, weight loss, and tiredness
      [confusion · fatigue · hypotension · poor appetite · vomiting · weight loss]
    - Women may report missed periods, low libido, and loss of underarm and pubic hair
    - Craving salty foods and feeling lightheaded on standing are common in the primary form
      [dizziness]
    - A history of taking steroid medication is an important clue, especially in longstanding cases
    - Fever can occur in any type and should prompt a search for an infection  [fever]
  SIGNS - what you find (4)
    - Poor skin turgor and darkened skin pigmentation can be seen on exam  [dehydration]
    - Look also for Cushingoid features - thin skin, stretch marks, swelling, weight gain, and
      muscle wasting  [muscle wasting · stretch marks · weight gain]
    - Up to half of patients go into shock without any preceding drop in blood pressure  [shock]
    - Neuropsychiatric changes can be part of the exam picture
  TESTS (7)
    - Low sodium with high potassium and low blood sugar can appear on chemistry
    - Cortisol, ACTH, renin, and aldosterone levels should be drawn along with a chemistry panel
    - An ACTH stimulation test distinguishes a primary (adrenal) cause from a secondary (pituitary)
      one
    - Anti-21-hydroxylase antibodies are the first test to check, since they cause the autoimmune
      destruction of the adrenal cortex
    - The secondary form causes low blood sugar but not dehydration, high potassium, or skin
      darkening
    - HIV and tuberculosis testing should be considered when the cause of late-onset disease is
      unclear
    - Anemia, low sodium, and high potassium are the most frequent lab findings in the chronic
      primary form
  IF NOT THIS - what else fits (5)
    - Adrenal crisis and adrenal hemorrhage are on the differential
    - Congenital adrenal hyperplasia should be considered
    - Histoplasmosis is a fungal infection that belongs on the list
    - Sarcoidosis, a granulomatous disease, is a differential too
    - Tuberculosis is a differential, especially relevant in developing countries

  Status  traced to the source above

1. HYDROCORTISONE                                         [1st line]
   Adult    15-25 mg daily in divided doses (e.g. 10 mg on waking, 5 mg at midday, 5 mg early
            afternoon to replicate physiological cortisol rhythm) - long-term lifelong
   Peds     8-10 mg/m2/day in 3 divided doses under pediatric endocrinologist management
   Source   Endocrine Society Guideline for Hormonal Replacement in Adrenal Insufficiency 2016
   Why      Physiological glucocorticoid replacement for adrenal insufficiency, timed across the day
            to mimic the body's own cortisol rhythm since the adrenal glands can no longer produce
            it; lifelong replacement rather than anti-inflammatory treatment.
   Caution  MUST DOUBLE or TRIPLE dose during intercurrent illness, fever, or acute stress ('sick-
            day rules').
            Issue steroid emergency card and self-injectable hydrocortisone emergency kit.
            Avoid late evening doses to prevent insomnia.
            Egypt has no registered oral hydrocortisone. The only pack in the register is an
            unlicensed import at around 66 EGP, and it is shown because it is the only thing there -
            not because it is a reliable supply. In a disease where running out means an adrenal
            crisis, that is the single most important practical fact about this prescription.
            So plan the supply before it is needed: confirm the patient can actually obtain the next
            box, keep a margin in hand rather than filling at the last tablet, and agree in advance
            what they do if the pharmacy cannot get it. Whether to replace it with an equivalent
            dose of a registered steroid is a decision for the treating physician, and it should be
            made at a clinic visit, not in the middle of an illness.

2. REFERRAL & SAFETY-NETTING (NO DRUG THERAPY)            [1st line]
   Adult    Addison's disease and secondary adrenal insufficiency occur and are life-threatening if
            missed; the GP recognises symptoms, may give an emergency steroid, and refers to
            endocrinology for long-term management.
   Peds     Children follow the same pathway: recognise and refer. Replacement steroid doses are
            started and titrated by a paediatric endocrinologist.
   Source   Adrenal Insufficiency - disease-level clinical article (adrenal-insufficiency-referral-
            clinical.txt)
   Why      Carries the referral criteria and warning signs for this condition, which apply
            whichever treatment is chosen.
   Caution  Adrenal crisis - low blood pressure, vomiting, collapse - is a medical emergency
            requiring immediate parenteral steroid and hospital transfer.

3. PREDNISONE                                             [2nd line]
   Adult    Prednisone 5 mg (2.5 to 7.5 mg) orally at bedtime - long-term lifelong
   Peds     The source gives no paediatric prednisone dose for maintenance replacement; its only
            prednisone maintenance dose is the adult one above. A child's replacement steroid is
            hydrocortisone 8-10 mg/m2/day in 3 divided doses, started and titrated by a paediatric
            endocrinologist.

   Why      Alternative longer-acting oral glucocorticoid replacement for chronic primary adrenal
            insufficiency.
   Caution  MUST DOUBLE or TRIPLE dose during intercurrent illness, fever, or acute stress ('sick-
            day rules').
            Issue steroid emergency card and self-injectable hydrocortisone emergency kit.

4. FLUDROCORTISONE                                        [add-on - not a substitute]
   Adult    50-200 mcg (0.05-0.2 mg) once daily in the morning for mineralocorticoid replacement in
            primary adrenal insufficiency - long-term lifelong
   Peds     50-150 mcg daily under pediatric endocrinologist care
   Source   Egyptian National Drug Formulary - Endocrine System 2024 (fludrocortisone monograph)
   Why      Synthetic mineralocorticoid that replaces the aldosterone activity lost in primary
            adrenal insufficiency, helping maintain sodium and potassium balance; added to
            glucocorticoid replacement rather than used alone, and needed only when the adrenal
            failure is primary.
   Caution  Required in primary adrenal insufficiency (Addison's); not required in secondary adrenal
            failure.
            Monitor blood pressure, serum potassium, and plasma renin activity.
