Impact of sarcopenia on variceal rebleeding in patients after endoscopic therapy: a multicenter retrospective cohort study based on propensity score matching.

BACKGROUND: Sarcopenia is a common complication of liver cirrhosis and can be used for predicting dismal prognostic outcomes. This study aimed to evaluate the role of sarcopenia in rebleeding and mortality of liver cirrhosis patients after endoscopic therapy. METHODS: The liver cirrhosis patients who received endoscopic treatment were enrolled. Propensity score matching (PSM) was used to overcome selection bias. Two-year rebleeding episodes and mortality after endoscopic therapy were recorded. RESULTS: A total of 109 (32.4%) sarcopenia patients were reported. Before PSM, the frequency of rebleeding was significantly higher in the sarcopenia group relative to the non-sarcopenia group (41.3% vs. 15.9%, p < 0.001). Moreover, the multivariable analysis revealed that sarcopenia (p < 0.001, HR:2.596, 95% CI 1.591-4.237) was independently associated with a 2-year rebleeding episode. After PSM, the sarcopenia group exhibited an increased rebleeding rate as compared with non-sarcopenia group (44.4% vs. 15.3%, p < 0.001). According to multivariable analysis, sarcopenia (p < 0.001, HR:3.490, 95% CI 1.756-6.938) was identified as a significant predictor for 2-year rebleeding. CONCLUSION: Sarcopenia was significantly associated with a high 2-year rebleeding rate in liver cirrhosis patients after endoscopic treatment. Therefore, the precise evaluation of a patient's nutritional status, including sarcopenia becomes mandatory before endoscopic treatment.

Influence of subcutaneous adipose tissue index on prognosis in cirrhotic patients following endoscopic therapy: a retrospective cohort study.

BACKGROUND: The relation of adipose tissue depletion with prognostic outcome of variceal bleeding among cirrhotic patients is still inconclusive. The present work explored whether adipose tissue, which was measured based on computed tomography (CT), was valuable for analyzing rebleeding and mortality among patients with variceal bleeding who had undergone endoscopic therapy. METHODS: The study encompassed cirrhotic patients who underwent endoscopic therapy to prevent variceal rebleeding between January 2016 and October 2022. The L3-level CT images were obtained. Besides, impacts of subcutaneous adipose tissue index (SATI), visceral adipose tissue index (VATI), as well as total adipose tissue index (TATI) on rebleeding and mortality among cirrhotic patients following endoscopic therapy were examined. RESULTS: In this work, our median follow-up period was 31 months. Among those adipose tissue indexes, only SATI exhibited an independent relation to higher rebleeding (HR 0.981, 95% CI, 0.971-0.991, p < 0.001) and mortality (HR 0.965, 95% CI, 0.944-0.986, p = 0.001) risks. Upon multivariate Cox regression, low SATI (male < 30.15 cm2/m2, female < 39.82 cm2/m2) was independently linked to higher rebleeding risk (HR 2.511, 95% CI, 1.604-3.932, p < 0.001) and increased mortality risk (HR 3.422, 95% CI, 1.489-7.864, p = 0.004) after adjusting for other predictors. Furthermore, subgroups were created based on using nonselective ß-blockers (NSBBs), demonstrating that quantitatively assessing SATI exerts a vital role in evaluating rebleeding incidence in patients with or without NSBB therapy. CONCLUSION: This study underscores the potential of quantifying SATI as a means for achieving a more accurate risk classification for individual patients and identifying patients that can gain more benefits from nutritional intervention.

Partial splenic embolization combined with endoscopic therapies and vasoconstrictive drugs reduces rebleeding in cirrhosis patients with acute variceal bleeding and hypersplenism: a multicenter randomized controlled trial.

BACKGROUND: This study aimed to compare the efficacy of partial splenic embolization (PSE) combined with endoscopic therapy and endoscopic therapy alone in cirrhosis patients with acute variceal bleeding (AVB) and hypersplenism. METHODS: Cirrhosis patients with AVB who visited three hospitals from June 2016 to June 2022 were prospectively enrolled and randomly allocated to either the endoscopic therapy combined with PSE group (EP group) or the endoscopic intervention group (E group) in a 1:1 ratio. The primary endpoint of the study was re-bleeding of varices during follow-up, and the secondary endpoints were the recurrence of varices, death, and adverse events. RESULTS: One hundred and fourteen patients were prospectively included, of whom 110 completed the trial. The risk of variceal re-bleeding (19.3% vs. 40.4% (23/57), p = 0.013) and variceal recurrence (28.1% vs. 63.2%, p < 0.001) five years after treatment was significantly lower in the EP group than in the E group, and the EP treatment was the only significant independent risk factor affecting variceal re-bleeding and variceal recurrence in patients. The mortality rate was comparable between the EP and E groups. Peripheral blood counts and liver function all improved significantly in the EP group compared to the E group during the follow-up (p < 0.05). CONCLUSIONS: The rates of variceal re-bleeding and recurrence were significantly lower in cirrhosis patients with AVB and hypersplenism after combined endoscopic and PSE treatment compared to those who were provided endoscopic treatment only. The peripheral blood counts and liver function were also improved significantly in EP group (NCT02778425).

Anticoagulation therapy early is safe in portal vein thrombosis patients with acute variceal bleeding: a multi-centric randomized controlled trial.

Portal vein thrombosis (PVT) and acute variceal bleeding (AVB) are frequent complications of cirrhosis. The efficacy, safety, and timing of anticoagulant treatment in cirrhotic patients with PVT and AVB are contentious issues. We aimed to establish the safety and efficacy of initiating nadroparin calcium-warfarin sequential (NWS) anticoagulation therapy early after esophageal variceal band ligation within PVT patients having cirrhosis and AVB. Cirrhotic patients having AVB and PVT who underwent EVL were included and randomly allocated to either the NWS therapy group (1-month nadroparin calcium by subcutaneous injection following 5-month warfarin through oral administration, n = 43) or the control group (without any anticoagulation therapy, n = 43). The primary endpoint was the rate of PVT recanalization. Secondary endpoints included major bleeding events mainly referring to variceal rebleeding (5-day failure, 14-day, 4-week, 6-week, and 6-month rebleeding rates) and mortality after EVL. The overall recanalization (complete and partial) rate in the NWS therapy group was significantly higher than that in the control group (67.4% vs. 39.5%, P = 0.009). Low Child-Pugh score (P = 0.039, OR: 0.692, 95% CI 0.488-0.982), D-dimer < 2.00 ug/mL (P = 0.030, OR: 3.600, 95% CI 1.134-11.430), and NWS anticoagulation therapy (P = 0.002, OR: 4.189, 95% CI 1.660-10.568) were the predictors of PVT recanalization through univariate analysis of binary logistic regression. NWS anticoagulation therapy (P = 0.003, OR: 4.506, 95% CI 1.687-12.037) was the independent factor of recanalization through multivariate analysis. Nobody bled except for variceal rebleeding. Five-day failure and 14-day rebleeding were zero. There were no significantly different in 4-week (2.3% vs. 4.7%, P = 1.000), 6-week (4.7% vs. 9.3%, P = 0.672) and 6-month rebleeding (18.6% vs. 20.9%, P = 0.787) between the two groups. There was no mortality during six months follow-up. Low serum albumin (P = 0.011, OR: 0.844, 95% CI 0.741-0.962), high MELD score (P = 0.003, OR: 1.564, 95% CI 1.167-2.097) and Child-Pugh score (P = 0.006, OR: 1.950, 95% CI 1.206-3.155) were predictors of rebleeding by univariate analysis of binary logistic regression analysis. The Child-Pugh score (7 [6-8] vs. 6 [5-7], P = 0.003) and albumin levels (33.93 ± 5.30 vs. 37.28 ± 4.32, P = 0.002) were improved in the NWS therapy group at six months. In PVT patients with cirrhosis and AVB, starting NWS anticoagulation therapy early after EVL was safe and effective. It has the potential to raise albumin levels and improve liver function.

LncRNA RPSAP52 promotes cell proliferation and inhibits cell apoptosis via modulating miR-665/STAT3 in gastric cancer.

LncRNA RPSAP52 is a newly identified functional molecular in several cancers, but its role in gastric cancer (GC) is currently unclear. This study aimed to investigate the biofunction of lncRNA RPSAP52 in GC. Quantitative polymerase-chain reaction (RT-qPCR) was employed to analyze the gene level of lncRNA RPSAP52 and miR-665. Cell proliferation capacity was evaluated via CCK-8 and colony formation assay. Flow cytometry was applied to detect cell cycle and cell apoptosis. Hematoxylin-eosin staining was conducted for histopathological analysis. Immunochemical staining was carried out to detect expression level of ki-67. Subcellular fractionation was performed to explore the position of lncRNA RPSAP52. The binding relationship among lncRNA RPSAP52, miR-665 and STAT3 was verified via luciferase reporter assay. RNA pull down experiments were used to verify the binding relationship between lncRNA RPSAP52 and miR-665. The STAT3 level was evaluated via Western blot. LncRNA RPSAP52 is significantly elevated in GC cells. Deletion of lncRNA RPSAP52 restrained cell proliferation and induced G0-G1 phase arrest, while expediting apoptosis in GC cells. Tumor growth in vivo was suppressed following lncRNA RPSAP52 depletion. MiR-665 was verified as the target of lncRNA RPSAP52. A ceRNA-sponge mechanism of lncRNA RPSAP52 on miR-665 was identified. Meanwhile, miR-665 functions as STAT3 sponge. MiR-665 overexpression and STAT3 depletion served the same functions as lncRNA RPSAP52 depletion in GC cells. LncRNA RPSAP52 exerted anti-cancer effects via modulating miR-665/STAT3 in GC.Abbreviations: Gastric cancer (GC); Quantitative polymerase-chain reaction (RT-qPCR); Helicobacter pylori (H. pylori); Roswell Park Memorial Institute 1640 (RPMI 1640); fetal bovine serum (FBS); glyceraldheyde 3-phosphate dehydrogenase (GAPDH); propidium iodide (PI); Cell counting kit-8 (CCK-8); radioimmunoprecipitation assay (RIPA); sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE); polyvinylidene fluoride (PVDF); enhanced chemiluminescence (ECL); Statistical Product and Service Solutions (SPSS); standard deviation (SD).
