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.
