Background/purpose: This study aimed to evaluate the usefulness of serum autotaxin, a novel liver fibrosis marker, for predicting post hepatectomy liver failure (PHLF) in patients undergoing hepatectomy for hepatocellular carcinoma (HCC).
Methods: Autotaxin was measured in sera from 269 patients undergoing hepatectomy for HCC. Correlations between autotaxin level, liver fibrosis stage (METAVIR F0-F4), and PHLF, as assessed by the International Study Group of Liver Surgery criteria, were analyzed.
Results: Median autotaxin concentrations correlated significantly with fibrosis stage (F0, 0.93; F1, 0.96; F2, 1.18; F3, 1.40; and F4, 1.47 mg/l; P < .0001). Autotaxin levels were significantly higher in female patients and hepatitis C virus antibody-positive patients compared with male or antibody-negative patients (P < .0001). PHLF grade ≥ B occurred in 25 patients (9.3%). A PHLF prediction model was constructed from four variables (autotaxin, resection rate, sex, and hepatitis C virus antibody positivity) and gave an area under the receiver operating characteristic curve of 0.8 (95% confidence interval [CI]: 0.69-0.87), which was superior to models based on ALPlat and resection rate (0.75, 95% CI: 0.64-0.83) or indocyanine green retention test and resection rate (0.72, 95% CI: 0.61-0.81).
Conclusion: Serum autotaxin has utility for predicting liver fibrosis and PHLF in patients with HCC.

Histological improvement of fibrosis in patients with hepatitis C who achieved a 5-year sustained virological response to treatment with direct-acting antivirals.

Background: The histological improvement in liver fibrosis in patients with hepatitis C who achieved a sustained virological response (SVR) to direct-acting antiviral (DAA) treatment has not been comprehensively investigated. Therefore, we assessed the histological changes in liver fibrosis among patients with hepatitis C who underwent long-term follow-up after achieving SVR to treatment with DAA.
Methods: This retrospective study enrolled 71 patients with hepatitis C who achieved SVR to treatment with DAA.
Serum autotaxin positively associates with hypertension in postmenopausal women: a single center study in China.

Aim: Autotaxin is an adipokine involved in metabolic disorders. The aim of the current study was to evaluate serum autotaxin levels in hypertensive postmenopausal women and establish a relationship between autotaxin and other comorbidities in this special group.
Methods: This single-center study included postmenopausal women who received annual health examinations at the First Affiliated Hospital, College of Medicine, Zhejiang University in Zhejiang, China.

Article Synopsis
- A study explored the potential of serum autotaxin (ATX) as a predictor for liver-related events (LRE) in patients with primary biliary cholangitis (PBC).
- During a median follow-up of 9.7 years of 190 untreated patients, those with ATX levels ≥1.086 mg/L experienced significantly more LRE compared to those with lower levels (33.3% vs 3.6%).
- The research suggests that ATX is a strong independent predictor for LRE, outperforming existing markers, and aligns with findings from a separate validation cohort of PBC patients.

Introduction: Autotaxin (ATX) is an adipokine known to affect energy metabolism and lipid homeostasis. We aimed to evaluate serum ATX levels in metabolic-associated fatty liver disease (MAFLD) and other metabolic disorders in postmenopausal women.
Methods: Postmenopausal women who received an annual health examination were included.

Article Synopsis
- Early-stage gastric cancer often goes undetected due to a lack of specific symptoms, resulting in late diagnoses and advanced disease, highlighting the need for new biomarkers for early detection and treatment matching.
- The study investigated the prognostic significance of ENPP2/Autotaxin (ATX) and lysophosphatidic acid (LPA) in Gastro-Esophageal Adenocarcinoma (GEA), finding that higher levels of these substances could indicate worse patient outcomes.
- Results showed that while ENPP2 mutations are infrequent, they are linked to lower overall survival, and surgical removal of tumors significantly reduced serum ATX and LPA levels, suggesting potential for targeted therapies based on these biomarkers in future clinical trials.
