Plateletcrit for predicting prognosis in patients with hepatic sinusoidal obstruction syndrome caused by pyrrolizidine alkaloid.

Abstract

BackgroundPlatelet index was reported to be used as a potential prognostic marker in patients with liver fibrosis. We aimed to explore the association between plateletcrit (PCT) and severity of hepatic sinusoidal obstruction syndrome (HSOS).MethodsSeventy consecutive patients who diagnosed as HSOS by CT and medical history during January 2017‐November 2021 were included. All patients were divided into two groups which confirmed as favorable prognosis and poor prognosis on the basis of Child‐Turcotte‐Pugh score system. The clinical manifestation and laboratory parameters of two groups were retrospectively selected. PCT was evaluated within two groups, and the diagnostic accuracy was evaluated by the area under the receiver operating characteristic curve.ResultsThe significant difference between the two groups not only in diarrhea, abdominal pain, abdominal distention, urine volume, and skin ecchymosis (p < 0.005), but also in WBC count, NE count, PLT count, TBIL, and D‐Dimer (p < 0.005) were found. The PCT level was significantly higher in HSOS patients with poor prognosis (0.169Â ± 0.060) than favorable prognosis patients (0.110Â ± 0.047). The area under the receiver operating characteristic curve of RDW in predicting poor prognosis was 0.781, with 67.70% sensitivity and 79.5%specificity.ConclusionsThe PCT level was correlated positively with the poor prognosis in HSOS patients. PCT can be a promising indicator for predicting prognosis in HSOS
