Abstract
Background:
Severe alcoholic hepatitis is a catastrophic disease with a mortality rate of up to 35–50% at 30 days. Bacterial infection is an important prognostic factor in patients with severe alcoholic hepatitis, but it is difficult to detect the presence of infection immediately. Procalcitonin (PCT) is a well-known inflammatory marker that can detect bacterial infections in various diseases early. Therefore, we aimed to evaluate the diagnostic accuracy of PCT for bacterial infection in severe alcoholic hepatitis.

Methods:
We prospectively enrolled patients with severe alcoholic hepatitis, defined as modified Maddrey’s Discriminant Function ≥ 32, from 10 medical centers. At admission, we performed an initial evaluation including physical examination, laboratory test, radiology, blood and urine culture, PCT, and C-reactive protein (CRP). We compared the receiver operating characteristic (ROC) curves of PCT and CRP for bacterial infection, systemic inflammatory response syndrome (SIRS), and sepsis among total patients.

Results:
A total of 108 patients with severe alcoholic hepatitis were enrolled. The number of bacterial infections, SIRS, and sepsis were 31 (28.7%), 41 (38.0%), and 19 (17.6%), respectively. The patients with bacterial infection had significantly higher MELD scores (24.0 vs. 15.0), PCT levels (1.5 vs. 0.4 ng/mL), and CRP levels (4.9 vs. 2.5 mg/dL) compared to those without bacterial infection. The area under the ROC curve (AUROC) of PCT vs. CRP for bacterial infection was 0.752 and 0.655, respectively (P = 0.113). The AUROC of PCT vs. CRP for SIRS was 0.699 and 0.662, respectively (P = 0.490). The AUROC of PCT vs. CRP for sepsis was 0.780 and 0.630, respectively (P = 0.027).

Conclusions:
Among patients with severe alcoholic hepatitis, PCT showed a trend of superior diagnostic performance in the early detection of bacterial infection and sepsis compared to CRP. Although PCT might have better potential to diagnose sepsis in the setting of severe alcoholic hepatitis, it is necessary to find more reliable diagnostic markers.
