The Prognostic Significance of the Platelet Count in Alcoholic Hepatitis.

ABSTRACT

Background and Aims: Thrombocytopenia is present in up to 76% of patients with chronic liver disease, and lower platelet counts (PCs) are associated with greater severity of portal hypertension. In this study, we assess the relationship of PC in patients with a clinical diagnosis of severe alcoholic hepatitis (SAH) with clinical severity and response to corticosteroid (CS) therapy. Methods: Clinical characteristics, treatment, and hospital outcomes for patients admitted with SAH were analyzed from an electronic health record system. Patients were categorized based on admission PC (k/uL) into 5 categories <50, 50-99, 100-149, 150-199, and ≥200. Frequency of complications (acute kidney injury, ascites, and hepatic encephalopathy), length of stay, and admission to an intensive care unit were analyzed across PC categories. Characteristics of patients who did and did not receive at least 4 days of CS therapy were compared. Results: Among 159 patients, 15 (9.4%) were in the PC < 50 category, 42 (26.4%) in PC 50-99, 51 (32%) in PC 100-149, 23 (14.5%) in PC 150-199, and 28 (17.6%) in PC ≥ 200. A higher admission PC was associated with greater white blood cell count, absolute neutrophil count, and total bilirubin (P < .05). Patients with higher PC on admission were more likely to receive steroids. PC was inversely associated with Lille score at treatment day 4 (P < .05). Conclusion: A higher PC in SAH was associated with a greater inflammatory response and total bilirubin. Patients with a higher PC were more likely to receive CS and have a favorable treatment response.
