Abstract:
Objective:To preliminary explore the changes in blood system in pyrrolizidine alkaloids (PAs)-related liver damage.Methods:General situation, liver function, biochemical blood test, routine blood test, coagulation function markers, etc., of 77 cases with drug-induced liver damage admitted to the Zhongshan Hospital Affiliated to Fudan University from 2012 to 2019 were retrospectively analyzed. Patients’ were divided into PA group, other traditional Chinese medicine group and Western medicine group according to their medication history. Simultaneously, the changes in liver function were observed in the established mice model of monocrotaline-induced liver damage. Liver tissues HE staining and blood routine indexes were observed.Results:24 cases received PA, 24 cases received other traditional Chinese medicine, and 29 cases received western medicine. Alanine aminotransferase was lower in PA group than the other two groups ( P < 0.05), and the total bilirubin and direct bilirubin were significantly lower than the other traditional Chinese medicine group ( P < 0.05). The peripheral platelet count of the PA group was (84.11 ± 26.91) ×10 9/L, which was significantly lower than the lower limit of normal, and had statistically significant difference with other traditional Chinese medicine and western medicine group ( P < 0.01). Thrombocytocrit, mean platelet volume and platelet indices of PA group were statistically different from the other two groups ( P < 0.05). The D-dimer level in patients with PA group was (2.62 ± 1.93) mg/L, which was higher than the upper limit of normal, and significantly higher than the D-dimer level of the other two groups of patients ( P < 0.01). Meanwhile, prothrombin time was longer in PA group than that of the other two groups ( P < 0.01), and platelets count were decreased significantly in the mouse model of monocrotaline-induced liver damage after alanine aminotransferase and aspartate aminotransferase elevation ( P < 0.01). Conclusion:PA-related liver damage has lower peripheral platelet counts, and the peripheral platelet counts of these patients are lower than other types of drug-induced liver damage. In addition, increased D-dimer in patients with PA-related liver damage indicate a potential risk of thrombosis.
