Abstract
Hepatoadrenal syndrome is described as a progressive impairment in the adrenocortical reserve in advanced liver disease resulting in relative adrenal insufficiency (AI). This can present as critical hypoglycemia and hyponatremia as in the case described.
54 year old male with past medical history of hypothyroidism, pericardial effusion, liver cirrhosis and prior alcohol use disorder presented to the hospital with altered mental status. He felt lethargic and complained of recurrent diarrhea for a month. His blood sugar was 30 mg/dl (n=70–140 mg/dl) for which he received dextrose and his mentation improved. He was hypothermic with stable vitals otherwise. There was no skin hyperpigmentation. Labs demonstrated sodium of 123 mmol/L (n=136–145 mmol/L) and pancytopenia. TSH, ammonia, renal and hepatic functions were within normal limits except mildly elevated AST and total bilirubin. Total protein, albumin, HDL, Insulin and cortisol levels were low. Hepatitis panel was negative. CT Chest, abdomen and pelvis revealed massive abdominopelvic ascites, hepatic cirrhosis and splenomegaly. Adrenal glands appeared normal. Urine studies were consistent with salt-wasting nephropathy. Patient was started on intravenous fluids as well as dexamethasone. Diagnostic and therapeutic paracentesis was performed. Cosyntropin stimulation test revealed a baseline AM cortisol of 2.0 ug/dl (n=4.3–22.4 ug/dl), 30 min value of 4.0 ug/dl and 60 min value of 5.8 ug/dl (n=18-22ug/dl). Delta cortisol level was also low. Treatment with hydrocortisone was initiated until ACTH levels became available. To rule out sarcoidosis, ACE levels were obtained, which were normal. Dihydroxy 1,25 Vitamin D levels were low. ACTH returned as 21.7 pg/ml (n=7.2–63.3 pg/ml). 21 hydroxylase antibody was negative. MRI brain with IV contrast demonstrated no pituitary mass or abnormality. Blood cultures, body fluid cultures, AMA and ASMA were negative. Anti- tTG and Anti Gliadin antibodies were positive confirming celiac disease. Patient was started on gluten free diet which resolved his diarrhea. He responded well to steroids however, he remained intermittently confused which was thought to be related to hypoglycemic brain injury. Patient was converted to hydrocortisone PO 20 mg in AM and 10 mg in PM and advised to follow up outpatient with endocrinologist and gastroenterologist.
Hepatoadrenal syndrome is an important differential to consider in patients with liver disease presenting with hypoglycemia and hyponatremia. It is a potentially life-threatening condition requiring immediate treatment and appropriate work up. The condition improves with corticosteroid replacement therapy.
