Anticoagulant therapy likely increases risk of bleeding in Gynura segetum-induced hepatic sinus obstruction syndrome.

This study aimed to analyze the clinical characteristics of Gynura segetum (Tusanqi)-induced hepatic sinusoidal obstruction syndrome (HSOS) and the benefits and risks of anticoagulant therapy for Tusanqi-induced HSOS. This was a retrospective analysis of 49 patients with Tusanqi-induced HSOS who were treated with anticoagulation or standard therapy between July 2006 and December 2022. Clinical manifestations included abdominal pain (n = 47) and peritoneal or pleural effusion (n = 46); 2 patients died. Nineteen patients requested standard medical treatment, while 30 were treated with anticoagulants. HSOS resolved within 6 months in 22 patients but did not resolve in 27 patients. The resolution rate was higher in the anticoagulant than standard treatment group (P = .037). Logistic regression analysis revealed that a history of chronic liver disease or treatment increased the risk of poor outcomes. Bleeding complications occurred in 6 patients in the anticoagulant treatment group. Early diagnosis and anticoagulant treatment are beneficial for rapid recovery after Tusanqi-induced HSOS. However, anticoagulant treatment is associated with the risk of multisite bleeding.

Development of a machine learning-based model to predict hepatic inflammation in chronic hepatitis B patients with concurrent hepatic steatosis: a cohort study.

Background: With increasingly prevalent coexistence of chronic hepatitis B (CHB) and hepatic steatosis (HS), simple, non-invasive diagnostic methods to accurately assess the severity of hepatic inflammation are needed. We aimed to build a machine learning (ML) based model to detect hepatic inflammation in patients with CHB and concurrent HS. Methods: We conducted a multicenter, retrospective cohort study in China. Treatment-naive CHB patients with biopsy-proven HS between April 2004 and September 2022 were included. The optimal features for model development were selected by SHapley Additive explanations, and an ML algorithm with the best accuracy to diagnose moderate to severe hepatic inflammation (Scheuer's system ≥ G3) was determined and assessed by decision curve analysis (DCA) and calibration curve. This study is registered with ClinicalTrials.gov (NCT05766449). Findings: From a pool of 1,787 treatment-naive patients with CHB and HS across eleven hospitals, 689 patients from nine of these hospitals were chosen for the development of the diagnostic model. The remaining two hospitals contributed to two independent external validation cohorts, comprising 509 patients in validation cohort 1 and 589 in validation cohort 2. Eleven features regarding inflammation, hepatic and metabolic functions were identified. The gradient boosting classifier (GBC) model showed the best performance in predicting moderate to severe hepatic inflammation, with an area under the receiver operating characteristic curve (AUROC) of 0.86 (95% CI 0.83-0.88) in the training cohort, and 0.89 (95% CI 0.86-0.92), 0.76 (95% CI 0.73-0.80) in the first and second external validation cohorts, respectively. A publicly accessible web tool was generated for the model. Interpretation: Using simple parameters, the GBC model predicted hepatic inflammation in CHB patients with concurrent HS. It holds promise for guiding clinical management and improving patient outcomes.

Pancreas lipiodol embolism induced acute necrotizing pancreatitis following transcatheter arterial chemoembolization for hepatocellular carcinoma: A case report and literature review.

RATIONALE: Transcatheter arterial chemoembolization (TACE) is recognized as one of the most commonly used modalities for non-surgical treatment for advanced hepatocellular carcinoma (HCC). Ectopic lipiodol embolism is an extremely rare complication of TACE. PATIENT CONCERNS: A 61-year-old man who had a 10-year history of cirrhosis caused by hepatitis B infection was diagnosed with ascites and HCC. Subsequently, the patient underwent TACE. However, he experienced persistent left upper abdominal pain, poor appetite, nausea, moderate fever and accompanied by elevation of serum and urine amylase on the 2nd and 3nd day after treatment. DIAGNOSES: The patient was diagnosed as having acute hemorrhagic necrotizing pancreatitis based on biochemical and inflammatory markers and CT findings. We deduced that the acute necrotizing pancreatitis was caused by a small branch of the left hepatic artery feeding the pancreas tail and embolizing the drug and lipiodol shunting to the tail of the pancreas. INTERVENTIONS: The patient was treated for 5 days according to the comprehensive treatment of acute necrotizing pancreatitis, by the inhibition of the secretion of pancreatic juice, relieving pain, and total parenteral nutrition and forbidding diet. The symptoms of the patient were observed to improve, and SAMS and urinary amylase (UAMS) level decreased to 143 IU/L and 254 IU/L, respectively and oral diet was permitted. OUTCOME: After a period of 2 weeks, the contrast abdominal CT showed slightly decreased fluid collection of the peri-pancreatic space. Moreover, it also showed flocculous and linear high-density shadow in the pancreatic tail, suggesting lipiodol deposition in the pancreatic tail. Subsequently, the symptoms were observed to abate, and the patient left the hospital. On the 21st day after TACE, the patient had a follow up in our outpatient department; the biochemical characteristics and inflammatory markers were observed to be normal CONCLUSION:: AP is still a rare complication after TACE. Etiology is still attributed to the occurrence of shunting and embolization drug reflux. Strategies strengthening the catheter tip that is placed as close to the distal branches of the hepatic artery for the possible careful injection of embolic materials is still the key to avoid post-TACE AP.

Rare spontaneous intrahepatic portosystemic shunt in hepatitis B-induced cirrhosis: A case report.

BACKGROUND: The portosystemic shunt is the pathway between the portal vein (PV) and systemic circulation. A spontaneous intrahepatic portosystemic shunt (SPISS) is a rare portosystemic shunt type. Here we report an extremely rare type of SPISS, a spontaneous intrahepatic PV-inferior vena cava shunt (SPIVCS). CASE SUMMARY: A 66-year-old woman was admitted to our hospital with the complaint of abdominal distention and a decreased appetite for 1 mo. The patient had a 20-year history of hepatitis B surface antigen positivity and a 5-year history of cirrhosis. She had been treated with Chinese herbal medicine for a long time. Liver function tests showed: alanine aminotransferase, 35 U/L; aspartate aminotransferase, 42 U/L; serum albumin (ALB) 32.2 g/L; and serum ascites ALB gradient, 25.2 g/L. Abdominal ultrasonography and enhanced computed tomography showed that the left branch of the PV was thin and occluded; the right branch of the PV was thick and showed a vermicular dilatation vein cluster in the upper pole of the right kidney that branched out and converged into the inferior vena cava from the bare area of the lower right posterior lobe of the liver. We diagnosed her with an extremely rare SPIVCS caused by portal hypertension and provided symptomatic treatment after admission. One week later, her symptoms disappeared and she was discharged. CONCLUSION: SPIVCS is a rare portosystemic shunt with a clear history of cirrhosis and portal hypertension. Clarifying the type PV shunt has important clinical significance.
