A

lcoholic hepatitis (AH) is associated with 40-50% mortality

at one month. Liver biopsy is often needed especially

for uncertain clinical diagnosis. Corticosteroids (CS) provide

50% survival benefit with their response evaluable only at

one week. Defects in bioenergetics or mitochondrial oxygen

consumption rate (OCR) in peripheral cells are shown in

systemic diseases. We tested the hypothesis that AH patients

with severe bioenergetics defects will progress to liver failure

and be non-responsive to CS (NRS). After informed consent,

20 mL blood was collected from ALD patients (with or without

AH) and healthy controls. Second 20 mL sample was collected

at one week, from AH patients receiving CS. Monocytes and

neutrophils were isolated within 30 and cellular bioenergetics

and OCR (pmol/min./mcg protein) were obtained using XF96

analyzer (Seahorse Biosciences). Of 78 ALD patients (37 AH)

and 40 healthy controls, OCR differed among 63 ALD patients

for basal, proton leak, non-mitochondrial, and oxidative burst

in monocytes and neutrophils. After controlling for age, WBC,

and MELD score, basal and ATP linked OCR predicted diagnosis

of AH. Bioenergetics inmonocytes improved among responders

but not in NRS on follow up assessment at one week of therapy.

Baseline cellular bioenergetics seems a promising biomarker for

personalizedmedicine in ALDpatients for a) diagnosis of AH and

b) predicting response to CS and outcome on follow up. Data in

larger multicenter population are needed before accepting use

of this novel biomarker in clinical practice.
