Only stress dose - Inj hydrocortisone 100 mg IV IF PT IS IN Adrenal shock .

Adv -8am serum cortsiol

Inspite of using the minimal dose of tapering steroids , pt has all these complaints , so a diagnostic uncertainity was prevailing .

1) COULD THIS PT HAVE UNDERLYING ENDOGENOUS CUSHINGS ?

A) In this patient ,it is not possible as his basal cortisol and post ACTH stimulation ,his serum cortisol levels were very low .(so ruling out possibility of endogenous cushings).

-( It is very rare to have this co-occurence of endogenous and exogenous cushings syndrome , although one such case was reported from malasiya .

But in this patient ,her basacl cortisol levels were not available/done .So hence they missed diagnosis .

We present a case of a 66-year-old lady who was noted to have typical features of Cushing's syndrome. As she gave a very clear history of ingesting exogenous GC for a year, no further work up was undertaken. Despite cessation of GC for a year, she continued to have thin skin and easy bruising. Upon admission for hypertensive emergency, her clinician took note of her changes and investigated her for endogenous Cushing's syndrome. Her cortisol post overnight dexamethasone suppression test was 707 nmol/l. Post low dose dexamethasone suppression test yielded a cortisol of 1133.2 nmol/l. 24 hours urine cortisol was 432.2 nmol/l. Plasma ACTH was 1.1 pmol/l, indicating an ACTH independent Cushing's syndrome. We proceeded with Computed tomography scan (CT scan) of adrenals which revealed a right adrenal adenoma measuring 4.4 × 3.4 × 4.0 cm. Right retroperiteneoscopic adrenalectomy was done. Histopathology examination was consistent with adrenal cortical adenoma with foci of myelolipoma. Post adrenalectomy she developed hypocortisolism secondary to contralateral adrenal suppression which lasted up to the present date. Her cutaneous and musculoskeletal manifestations improved substantially. Co-occurrence of endogenous and exogenous Cushing's syndromes is uncommon but should be considered in patients whose Cushingnoid features do not resolve after cessation of exogenous GC. )

2) OR is patient using other steroids/ ayurvedic/homeo medications ,which he is concealing the history.

is he doing it for medical attention ?

is he using the medications as prescribed or using double doses ?? although pt and his attender denies any such history .

all these questions remain un-answerwed .

Current plan - to admit the patient and stop tab hisone 2.5 mg and monitor him for any adrenal crisis.

fasting 8 am serum cortisol to be sent again .

Hisone 2.5 mg tablet was stopped for 2 days. No symptoms as of now.

26/11/21 - Repeat 8am fasting serum cortisol is 0.54 mcg/dl

ACTH stimulation test was done . Report awaited .

1/12/21 -Pt was observed for one week and had no episodes of hypotension .

So after taking patient and his attenders consent ,and explaining them about condition and course and prognosis of disease , tapering dose of steroids was stopped .

Pt was explained to take stress dose of steroid INJ HYDROCORTISONE 100mg IV STAT ,in case of fever,acute illnesses, syncope and hypotension .
