I'd like to know the following:

Was a CMP, CBC, A1C, Cortisol, or ACTH drawn?

Was a ACTH stim test or hypoglycemia test done?

Any imaging?

I have a hunch, as I've seen a similar case before.

I’ll be posting labs in a few days! Do you recall where you saw the other case? I’ve been working up several cases for my pathophysiology students- trying to be original and interesting!

I've seen a patient with this issue before, not a case study.

Nonetheless, I think it's a great case study.

Awesome! Thanks for playing!

Thanks so much for reading and commenting - here's the solution!

This patient has Addison’s disease caused by damage to the adrenal glands as evidenced by the abdominal CT. This primary adrenal insufficiency is confirmed by the Rapid ACTH stimulation test showing minimal elevation in cortisol with high levels of ACTH. The cortex of the adrenal gland has been damaged most likely by the latent tuberculosis the patient experienced. This has led to symptoms that relate to low levels of corticosteroids including glucocorticoids which support the body converting food to energy and help the body respond to stress; mineralcorticoids which maintain sodium and potassium balance and keep blood pressure normal and androgens which maintain secondary sexual characteristics like axillary hair.

Symptoms often develop so slowly they are ignored and include extreme fatigue, weight loss and decreased appetite, darkening of the skin, low blood pressure, salt craving, hypoglycemia, N/V/D, abdominal, joint or muscle pain, irritability, depression, body hair loss and sexual dysfunction in women. Untreated Addison’s disease can cause an Addisonian crisis as a result of stress, so people with addison’s (a lifelong disease since the adrenal glands don’t grow back) may carry a glucocorticoid injection kit with them and wear a medical alert bracelet. Patients are typically prescribed Cortef (hydrocortisone), prednisone or methylprednisone to replace cortisol. The hormones are given on a schedule to mimic normal 24 hour fluctuations of levels.

Here are the responses from members who came to the Admin Help Desk to submit their diagnoses for our 2nd Case Study Investigation (CSI): I’m too tired to walk the dog …

CONGRATULATIONS and THUMBS UP to those with the correct diagnosis!

What great diagnosticians!!

Thank you to all who participated. We hope you enjoyed this CSI.

Be watching for the next CSI installment coming very soon!

? Dx: Addison's disease. Pt has hx of TB and should be evaluated for active disease such as adrenal TB as a cause of Addison's/pt's symptoms.

Thank you.

? I think she has Addison's Disease. The fatigue and salt craving then weight loss keyed me in.

? With the help of Google and Medscape my guess is Addison's Disease?

Copied and pasted messy notes from my thinking process:

more info:
-CBC (electrolytes and other fun things)
-date of last menstrual cycle (menopause? but amenorrhea is also part of Addison's disease)
-liver function (acetaminophen cause damage?)
-blood sugar

handy dandy Google told me we might need:
-short synacythen test
-blood electrolyte and plasma renin tests
-anti adrenal antibody test
-x-ray, Cat scan, or US of and to see size of adrenal glands to know damage

(but like, IDK which ones are most useful for Dx, available, and cost effective)

Things that line up with Addison's
-weakness
-progressive fatigue
-low appetite or unplanned weight loss
-dizziness or fainting due to low BP
-salt craving
-hyperpigmentation
-absence of axillary and pubic hair and decreased body hair in females
-few aches and pains
-weak periph pulses
-dry mucous membranes
-poor skin turgor
-mild nausea
-latent TB

not sure if explained by Addison's:
-flat affect (part of fatigue?)
-pre-diabetic Hx could affect the glucose measurement. hypoglycemia common w/addison's though

? The latent TB, hyperpigmentation,salt cravings, light headedness,fainting and GI problems are all hallmark indicators of Addison's disease

Is it hypothyroidism?

Hello! I am an aspiring nurse. I'm currently competing to get into a nursing program but have yet to be selected.

Now to the Case Study. My findings suggest that this pt might be experiencing Liver failure due to a combination of prolonged daily usage of acetaminophen and alcohol usage attribution.

? The patient in the current article possibly has Addison's disease. Need ACTH, cortisol stim test, CMP, CBC.

@BlueShoes12

? I'm guessing Addison's disease based off the fatigue, weight loss, abnormal pigmentation, and hypotension.

Has a cortison, ACTH or A1C been drawn?

? Adrenal insufficiency (Addison's)

@JBudd

My first though was hyponatremia, followed closely by hypothyroidism.

@kidfloat

? Blood work? Cortisol?

Addisons?

@NRSKarenRN

? Had patient in acute adrenal failure, late effect of TB on telemetry unit .... Addisons disease

Addisons disease signs include:

  • Extreme fatigue
  • Weight loss and decreased appetite
  • Darkening of skin (hyperpigmentation)
  • Low blood pressure, even fainting
  • Salt craving
  • Low blood sugar (hypoglycemia)
  • Nausea, diarrhea or vomiting (gastrointestinal symptoms)
  • Abdominal pain
  • Muscle or joint pains
  • Irritability
  • Depression or other behavioral symptoms

? My hunch is that the patient is suffering from Addison's disease.

Some signs and symptoms to support this include:

Presentation of hyponatremia, which seems to be confirmed by

  • low BP
  • fatigue
  • abnormal turgor
  • excessive salt cravings followed by loss of appetite, nausea

When lab results came back, this warranted further investigation into HPA axis issues due to:

  • Na 125 meq/L.
  • abnormal, alarmingly low rapid ACTH stim test
  • low cortisol levels
  • mild bilateral atrophy of adrenal glands

I'd recommend:

  • immediate electrolyte replenishment via IV so the pt does not drop below Na 125 meq/L and suffer severe health consequences (ex: coma)
  • oral corticosteroids followed by referral to endocrinology for long term treatment
