Multiorgan dysfunction syndrome due to high-dose cantharidin poisoning:A case report

BACKGROUND This report delves into the diagnostic and therapeutic journey undertaken by a patient with high-dose cantharidin poisoning and multiorgan dysfunction syndrome(MODS).Particular emphasis is placed on the comprehensive elucidation of the clinical manifestations of high-dose cantharidin poisoning,the intricate path to diagnosis,and the exploration of potential underlying mechanisms.CASE SUMMARY A patient taking 10 g of cantharidin powder orally subsequently developed MODS.The patient was treated with supportive care,fluid hydration and antibiotics,and hemoperfusion and hemofiltration therapy for 24 h and successfully recovered 8 d after hospital admission.Cantharidin poisoning can cause lifethreatening MODS and is rare clinically.This case underscores the challenge in diagnosis and highlights the need for early clinical differentiation to facilitate accurate assessment and prompt intervention.CONCLUSION This article has reported and analyzed the clinical data,diagnosis,treatment,and prognosis of a case of high-dose cantharidin poisoning resulting in MODS and reviewed the relevant literature to improve the clinical understanding of this rare condition.

Protective effect of glycyrrhetinic acid against cantharidin-induced hepatotoxicity through reducing oxidative stress in mice

Background:Cantharidin(CTD)is a commonly used natural product with anticancer properties;however,it has significant adverse effects,particularly hepatotoxicity.Glycyrrhetinic acid(GA),the active component of licorice,shows potential hepatoprotective effects.The protective effects and mechanism of GA against CTD-induced hepatotoxicity are still unclear.Objective:This study aims to elucidate the effect and mechanism of GA on CTD-induced hepatotoxicity in mice experiments.Methods:Construction of CTD-induced hepatotoxicity models and oral gavage GA intervention for 14 d.The liver index,ALT,AST and LDH levels in the serum of the mice were examined;HE staining was performed to observe pathological changes in the liver.The MDA level and SOD activities in liver tissue were tested.Western blot was conducted to determine Keap1/Nrf2 signaling pathway-related protein expression.Results:The results showed that GA significantly reduced the levels of ALT,AST,and LDH in the serum,which were increased by CTD.Additionally,it also exerted a substantial inhibitory effect on the reduction of SOD activity and the elevation of malondialdehyde content in liver tissue.Notably,the phenomena of nuclear swelling,necrosis,and inflammatory infiltration of liver tissue were significantly attenuated following oral administration of GA in mice.Subsequent research has demonstrated that GA effectively suppressed the CTD-triggered upregulation of Keap1 while increasing the CTD-induced downregulation of Nrf2,HO-1,and NQO1.Conclusion:These findings suggested that GA may protect against CTD-induced hepatotoxicity in mice by exerting antioxidative stress through the Keap1/Nrf2 signaling pathway.

Inhibitory Effect of Cantharidin on Proliferation of A549 Cells

Objective： To study the inhibition of Cantharidin against the proliferation of human lung cancer A549 cells and its mechanism. Methods： MTT assay was employed to determine the inhibition of Cantharidin against proliferation of A549 cells and flow Cytometry was applied to analyze A549 cell cycle and the effect of Cantharidin on cell cycle. Results： Cantharidin showed inhibition against the proliferation of A549 cells, and the inhibition was mediated by blocking A549 cell cycle at G2/M phase significantly. Conclusion： Cantharidin exhibits inhibition against the proliferation of human lung cancer A549 cells.

Cantharidin suppresses HCT116 colorectal carcinoma cell proliferation and migration by changing the cytoskeleton structure

Background:Cantharidin (CTD),a natural toxin produced from Chinese blister beetles,has extensive anti-tumor activity.The present study investigated the effect of CTD on a human colon cancer cell line to elucidate potential new insights regarding the mechanism(s) through which CTD exerts its anti-tumor effects.Materials and methods:The inhibitory effect of CTD on human colon cancer HCT116 cells was evaluated using the IncuCyte ZOOMTM analyzer.Apoptotic cells were detected by Annexin V-FITC/PI assay and cell cycle was evaluated with flow cytometry following propidium iodide staining.Alterations in F-actin microfilaments were analyzed by FITC-phalloidin staining and morphological changes were evaluated with a laser scanning confocal microscope.Cell migration assay was carried out to investigate the effects of CTD on migration of HCT116 cells in vitro.Results:CTD exhibited a significant growth inhibitory effect on HCT116 cells accompanied by an increase in G2/M phase cells,without a significant effect on apoptosis.CTD-treated cells also exhibited a dramatic collapse in their microfilament network and a significant reduction in cell adhesion.Conclusion:CTD inhibits growth by increasing G2/M phase cells and decreasing S phase cells,revealing that CTD exerts a significant growth inhibitory effect primarily through an inhibition of cell cycle progression (a cytostatic effect).Moreover,a negative effect on cell migration may also constitute a contributing factor to its anti-tumor potential.These findings suggest the potential use for developing CTD as a novel anti-cancer therapy that targets metastasis Giving full play to CTD may inhibit tumor transfer.

Analysis of the metabolic mechanism in Cantharidin-induced hepatotoxicity in LO2 cells using lipidomics analysis

Background:Cantharidin is a major active compound from Banmao(Mylabris).Cantharidin has obvious anticancer activity.However,its clinical application is limited due to serious hepatotoxicity.Methods:To evaluate the toxicity of human liver LO2 cells exposed to cantharidin by lipidomics.After exposing LO2 cells to different doses of cantharidin,the metabolites in LO2 cells were analyzed by nontargeted lipidomics based on liquid chromatography-mass spectrometry.Partial least-squares discriminant analysis and orthogonal partial least-squares discriminant analysis were used to screen differentially expressed metabolites,and then the main metabolic pathways were analyzed.Results:Pattern recognition analysis showed that the lipid metabolite profiles were changed significantly after cantharidin treatment,and 39 differential lipid metabolites were found.Additional analysis showed that these metabolites could mainly involve the metabolic pathways of triglyceride and acylcarnitine for cantharidin toxicity to LO2 cells.Conclusion:Cantharidin has obvious toxic effects on LO2 cells from the perspective of lipid metabolism.Moreover,the LO2 cytotoxicity induced by cantharidin is mainly related to the disorder of triglyceride and acylcarnitine metabolism.It can provide a scientific basis for cantharidin-induced hepatotoxicity.

Physicochemical Properties and Gastric Mucosa Irritation of Cantharidin-hydroxypropyl-β-cyclodextrin Inclusion Complex

Objective To increase the solubility and relieve the mucous irritation of cantharidin (CA) by preparing cantharidin-hydroxypropyl-β-cyclodextrin (CA/HP-β-CD) inclusion complex. Methods The inclusion complex was prepared by co-evaporation method and characterized by differential scanning calorimetry (DSC), X-ray diffractometry (XRD), and nuclear magnetic resonance (NMR). Results The disappearance of CA as well as the shift of exothermic peaks shown in DSC results indicated the complexation phenomenon. XRD results showed that the crystalline CA pattern had disappeared, and in NMR results, H-5 shifted from δ 3.731 to 3.695 after complexation and H-2 shifted from δ 3.626 to 3.598, which suggested that part of the drug had entered the HP-β-CD cavity to form an inclusion complex. The solubility increased 10.3 times after complexation and the mucous irritation of CA was relieved remarkably. Conclusion Through complexation with HP-β-CD, the solubility and dissolution rate of CA are improved significantly, and the irritation of musous is relieved.
