Clinical characterization and mechanism exploration of Fructus Psoraleae-induced hepatotoxicity in zebrafish AO Ting, WANG Ningning, ZHOU Lei, DENG Huifang, YANG Xingxin, ZHOU Wei, SHEN Pan, GAO Yue Chinese Journal of Pharmacovigilance    2024, 21 (6): 611-616.   DOI: 10.19803/j.1672-8629.20240317 Abstract （137）      PDF（pc） （2408KB）（949）       Knowledge map    Save Objective To investigate the effects of Fructus Psoraleae (FP) in accordance with clinical medicinal characteristics on the liver of zebrafish based on the proteome and its potential hepatotoxic mechanism. Methods Adult zebrafish were continuously treated with low, medium, and high concentrations of FP decoction (0.025, 0.050, 0.100 mg·mL-1) for 21 days. Changes in zebrafish body weight, liver histopathology, and levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the serum detected by enzyme-linked immunosorbent assay (ELISA) were compared. Potential hepatotoxic mechanisms were studied based on identified liver proteome through cluster and pathway enrichment analysis, and molecular docking was used to explore potential toxic targets of the main hepatotoxic components of FP. Results Zebrafish treated with FP decoction showed a significant decrease in body weight compared to the control group, with a more pronounced weight loss as the concentration increased. The levels of ALT and AST were significantly elevated in the Angelica sinensis treated group, with a dose-dependent effect (P < 0.05). Hematoxylin-eosin (HE) staining results showed disordered arrangement of liver cells, increased gaps, and phenomena such as steatosis and immune cell infiltration in the liver tissues of the FP-treated group compared to the control group, with the severity of the lesions worsening with increasing concentration. Cluster and functional enrichment analysis of the proteome indicated that FP affected the expression of lipid and energy metabolism-related proteins, including acetyl-CoA acetyltransferase 1 (acat1), 3-hydroxyacyl-CoA dehydrogenase (ehhadh), succinate dehydrogenase (sdha) and succinate dehydrogenase (sdhb) in the zebrafish liver, and molecular docking revealed the potential of the main hepatotoxic components in FP to bind to these proteins. Conclusion Long-term Fructus Psoraleae administration causes hepatic lipid metabolism disorders, ultimately resulting in hepatotoxicity characterized by steatosis, with the potential toxicity mechanism involving abnormal expression of lipid and energy metabolism-related proteins induced by main hepatotoxic compounds in FP.

Methods A retrospective study was conducted on a patient with cerebral infarction who developed a generalized rash after polypharmacy (amlodipine, aspirin, atorvastatin, urinary kallidinogenase and edaravone dexborneol) was conducted. The rash worsened even after discontinuing urinary kallidinogenase and edaravone dexborneol and switching aspirin to clopidogrel. The rash subsided only after discontinuing all medications except for antiallergic drugs. When clopidogrel and amlodipine were reintroduced, the rash did not recur. The Naranjo score and literature review were used to analyze the potential allergenic drug. Results Based on the clinical presentation of the rash and its relationship with the timing of medication, combined with the Naranjo score of 5 for atorvastatin, it is very likely that atorvastatin is the drug causing the patient’s rash. Conclusions Clinicians should be aware that atorvastatin can cause severe generalized rash in chronic diseases patients a few days after administration during polypharmacy.

The most common clinical manifestations were rashes (51/51, 100%) and fever (31/51, 60.78%). The primary rash was papules or pustules with central necrotic crusting. All patients had skin rashes, 24 of whom (24/51, 47.06%) developed rashes that were limited to the genitals and perianal area, 12 (12/51, 23.53%) started with generalized pustules, and 15 (15/51, 29.41%) had rashes that were initially localized before being generalized. 31 cases (31/51, 60.78%) had fever, which did not necessarily follow the rash. There were 32 (32/51,62.75%) HIV-positive patients, 2 (2/51, 3.92%) were in the AIDS stage (CD4+ T lymphocytes < 200 cells·μL-١), and one died. There were 25 cases (25/51, 49.02%) with positive serological tests for syphilis. As symptomatic treatment, 39 patients (39/51, 76.47%) were treated with symptomatic supportive care, including topical and oral anti-infective drugs(such as fusidic acid cream, povidone iodine solution, valaciclovir and cefprozil), 12 patients received no medication, and most of the outcomes were good except for one death. Conclusion Patients during this Mpox epidemic were mostly men who had sex with men, and the clinical manifestations were primarily pustules with central necrotic scabs. Some patients were accompanied by fever, AIDS complicated with Mpox could cause death, and most patients had a good prognosis after symptomatic treatment.
