The spleen is the graveyard of CD4+ cells in patients with immunological failure of visceral leishmaniasis and AIDS.

BACKGROUND: Visceral leishmaniasis (VL), or kala-azar, is a common comorbidity in patients with AIDS in endemic areas. Many patients continue to experiences relapses of VL despite virological control, but with immunological failure. These patients remain chronically symptomatic with hypersplenism, for example with anemia, leukopenia, and thrombocytopenia, and are at risk of severe co-infection due to low CD4+ count. Therefore, in this study, splenectomized patients with VL and HIV infection were investigated to understand why the CD4+ count fails to recover in these patients, evaluating the importance of spleen mass for hypersplenism and immunological failure. METHODS: From a retrospective open cohort of 13 patients who had previously undergone splenectomy as salvage therapy for relapsing VL, 11 patients with HIV infection were investigated. This study compared the patients' complete blood cell count (CBC) and CD4+ and CD8+ cell counts before and after splenectomy with respect to spleen weight. RESULTS: CBC was substantially improved after splenectomy, indicating hypersplenism. However, to the best of our knowledge, this is the first study to show that spleen mass is strongly and negatively correlated with CD4+ cell count (ρ = -0.71, P = 0.015). CONCLUSIONS: This finding was unexpected, as the spleen is the most extensive lymphoid tissue and T-lymphocyte source. After reviewing the literature and reasoning, we hypothesized that the immunological failure was secondary to CD4+ loss initially by apoptosis in the spleen induced by productive HIV infection and, subsequently, by pyroptosis sustained by parasitic infection in spleen macrophages.

The decreased risk of hepatocellular carcinoma in hepatitis B virus-related cirrhotic portal hypertension patients after laparoscopic splenectomy and azygoportal disconnection.

BACKGROUND: Posthepatitic cirrhosis is one of the leading risk factors for hepatocellular carcinoma (HCC) worldwide, among which hepatitis B cirrhosis is the dominant one. This study explored whether laparoscopic splenectomy and azygoportal disconnection (LSD) can reduce the risk of HCC among patients with hepatitis B virus (HBV)-related cirrhotic portal hypertension (CPH). METHODS: A total of 383 patients with HBV-related CPH diagnosed as gastroesophageal variceal bleeding and secondary hypersplenism were identified in our hepatobiliary pancreatic center between April 2012 and April 2022, and conducted an 11-year retrospective follow-up. We used inverse probability of treatment weighting (IPTW) to correct for potential confounders, weighted Kaplan-Meier curves, and logistic regression to estimate survival and risk differences. RESULTS: Patients were divided into two groups based on treatment method: LSD (n = 230) and endoscopic therapy (ET; n = 153) groups. Whether it was processed through IPTW or not, LSD group showed a higher survival benefit than ET group according to Kaplan-Meier analysis (P < 0.001). The incidence density of HCC was higher in the ET group compared to LSD group at the end of follow-up [32.1/1000 vs 8.0/1000 person-years; Rate ratio: 3.998, 95% confidence intervals (CI) 1.928-8.293]. Additionally, in logistic regression analyses weighted by IPTW, LSD was an independent protective predictor of HCC incidence compared to ET (odds ratio 0.516, 95% CI 0.343-0.776; P = 0.002). CONCLUSION: Considering the ability of LSD to improve postoperative survival and prevent HCC in HBV-related CPH patients with gastroesophageal variceal bleeding and secondary hypersplenism, it is worth promoting in the context of the shortage of liver donors.

Risk factors for portal vein system thrombosis after partial splenic embolisation in cirrhotic patients with hypersplenism.

AIM: To determine risk factors for portal venous system thrombosis (PVST) after partial splenic artery embolisation (PSAE) in cirrhotic patients with hypersplenism. MATERIALS AND METHODS: Between March 2014 and February 2022, 428 cirrhotic patients with hypersplenism underwent partial splenic artery embolisation and from these patients 208 were enrolled and 220 were excluded. Medical records of enrolled patients were collected. Computed tomography (CT) images were reviewed by two blinded, independent radiologists. Statistical analyses were performed by using SPSS. RESULTS: Progressive PVST was observed in 18.75% (39/208) of cirrhotic patients after PSAE. No significant differences in peripheral blood counts, liver function biomarkers, and renal function were observed between the patients with progressive PVST and the patients without progressive PVST. The imaging data showed significant differences in PVST, the diameters of the portal, splenic, and superior mesenteric veins between the progressive PVST group and non-progressive PVST group. Univariate and multivariate analysis demonstrated portal vein thrombosis, spleen infarction percentage, and the diameter of the splenic vein were independent risk factors for progressive PVST. Seventeen of 173 (9.83%) patients showed new PVST; the growth of PVST was observed in 62.86% (22/35) of the patients with pre-existing PVST. Spleen infarction percentage and the diameter of the splenic vein were independent risk factors for new PVST after PSAE. CONCLUSION: The present study demonstrated portal vein thrombosis, spleen infarction percentage, and the diameter of the splenic vein were independent risk factors for PVST after PSAE in cirrhotic patients with hypersplenism.

The Role of the Spleen in Portal Hypertension.

As liver disease progresses, intrahepatic vascular resistance increases (backward flow theory of portal hypertension) and collateral veins develop. Adequate portal hypertension is required to maintain portal flow into the liver through an increase in blood flow into the portal venous system (forward flow theory of portal hypertension). The splenic artery resistance index is significantly and selectively elevated in cirrhotic patients. In portal hypertension, a local hyperdynamic state occurs around the spleen. Splenomegaly is associated with a poor prognosis in cirrhosis and is caused by spleen congestion and by enlargement and hyperactivation of splenic lymphoid tissue. Hypersplenism can lead to thrombocytopenia caused by increased sequestering and breakdown of platelets in the spleen. The close relationship between the spleen and liver is reflected in the concept of the hepatosplenic axis. The spleen is a regulatory organ that maintains portal flow into the liver and is the key organ in the forward flow theory of portal hypertension. This review summarizes the literature on the role of the spleen in portal hypertension.

Baseline ALBI Grade Predicts Benefits After Splenectomy for Cirrhotic Patients with Hypersplenism.

PURPOSE: Splenectomy is an effective treatment for correcting cytopenia caused by hypersplenism secondary to cirrhosis. However, other potential benefits have not been well characterized. In this study, we investigated the value of splenectomy as it relates to improvement in hepatic function, liver regeneration, and health-related quality of life, and their association with baseline characteristics to clarify which patients may benefit the most from splenectomy. METHODS: Patients with hypersplenism secondary to cirrhosis treated by splenectomy were retrospectively reviewed. Hepatic function was reflected by hematologic indices and albumin-bilirubin score. Liver volume was measured by imaging software, and quality-of-life was assessed by a 36-question short-form questionnaire. The changes in these three aspects after splenectomy were evaluated in the whole cohort and compared between subgroups. RESULTS: The hepatic function of the patients significantly improved after splenectomy, and this was reflected by elevated serum albumin, shortened prothrombin time, and decreased albumin-bilirubin score. Patients with baseline albumin-bilirubin grade 2 or 3 and age < 56 years showed significantly decreased albumin-bilirubin score after splenectomy, whereas other subgroups did not. Moreover, liver volume increased remarkably after splenectomy in patients with baseline albumin-bilirubin grade 1, but not in those with grade 2 or 3. Significant improvement in quality-of-life occurred in the entire cohort after splenectomy, but more profound improvement was found in patients with albumin-bilirubin grade 2 or 3. CONCLUSIONS: Splenectomy improves hepatic function, increases liver volume, and also improves quality-of-life in different subsets of patients with cirrhosis and hypersplenism. Baseline characteristics, such as albumin-bilirubin grade and age, are helpful in estimating the potential benefits of splenectomy for patients before surgery.

Gastro-colic Fistula-associated Hypersplenism Causes Pancytopenia in a Patient with Crohn's Disease.

A 24-year-old woman was admitted to our hospital due to abdominal pain and a high fever. She was diagnosed with ileocolonic Crohn's disease (CD), complicated with a gastro-colic fistula and splenomegaly. After initial treatment with an infliximab-biosimilar, all blood cell line counts markedly decreased. Three-dimensional reconstructed computed tomography revealed splenic vein narrowing. Thus, her pancytopenia was deemed to have likely been caused by hypersplenism. Surgery was performed, and clinical remission was maintained without pancytopenia. This is the first report of a CD patient with pancytopenia caused by hypersplenism that was triggered by gastro-colic fistula-associated splenic vein obstruction.

REX SHUNT IN CHILDREN: COULD DYSFUNCTION BE PROGNOSED? A RETROSPECTIVE ANALYSIS.

OBJECTIVE: The aim: To analyze retrospectively our experience of Rex shunt in children with symptomatic portal hypertension, its effect on hypersplenism regression and varices eradication, assess shunt survival and investigate risk factors, that could lead to shunt dysfunction and thrombosis. PATIENTS AND METHODS: Materials and methods: 24 children (16 males, 8 females) ,with portal hypertension included into the study. All surgeries were performed within single center in a period from January 2010 to March 2022. Follow up period was 6.75±1.19 years. RESULTS: Results: Age at diagnosis was 5.39±0.64 years. 5 (20.8%) had umbilical catheter in anamnesis. 16 (66.7%) manifested bleeding episodes as the first sign of portal hypertension. 9 (37.5%) of children manifested severe hypersplenism. Age at Rex shunting was 7.5±0.7 years. In 7 (31.8%) cases Rex shunt thrombosis occurred. 1 successful thrombectomy and 6 splenorenal shunting were performed. Kaplan-Meyer analysis showed Rex shunt survival 0.670 (95%CI 0.420-0.831). Logistic regression model indicated thrombocytes count (p=0.0423) and cytopenia (p=0.0272) as factors that could influence shunt thrombosis. Follow-up group included 18 patients. Spleen volume regression became significant by 1 p/o year p<0,05, thrombocytes significant increasement reached in 1 p/o months (p<0.01), varices involution was achieved by 1 p/o year (p<0,001). CONCLUSION: Conclusions: Rex shunt effectiveness in study group was 70.9%., shunt survival assessed 0.670 (95%CI 0.420-0.831). Rex shunt was effective in bleeding prophylaxis in all patients of follow up group. Preoperative thrombocytes count (p=0.0423) and cytopenia (p=0.0272) were detected as factors that could influence shunt thrombosis, that is to be considered in RS preoperative period and require following studies.

Nomogram for prediction of portal vein system thrombosis after splenectomy for hypersplenism in patients with Wilson disease.

BACKGROUND: The occurrence of portal vein system thrombosis (PVST) after splenectomy in patients with Wilson disease (WD) can lead to serious complications. The early identification of high-risk patients can help improve patient prognosis. This study aimed to establish and validate a personalized nomogram for assessing the risk of PVST after splenectomy in patients with WD and hypersplenism. METHODS: We retrospectively collected the data from 81 patients with WD and hypersplenism who underwent splenectomy. Based on whether PVST occurred within a month after the operation, they were divided into the PVST group and the non-PVST group. The clinical data of the 2 groups were compared, and univariate analysis was used to select the statistically significant features and incorporated into the least absolute shrinkage and selection operator (LASSO) regression model for optimization. Multivariate logistic regression analysis was used to determine the independent risk factors for PVST after splenectomy, which were then applied to establish a personalized nomogram. We calculated the concordance (C)-index and drew the receiver operating characteristic (ROC) curve, the model calibration curve, and the clinical decision analysis (DCA) curve to evaluate the accuracy, calibration, and clinical applicability of the model, respectively. We used bootstrapping for internal validation of the model. RESULTS: Univariate analysis showed that the differences in preoperative portal vein diameter and velocity of portal blood flow, postoperative mean platelet volume (MPV), mean platelet distribution width (PDW), D-dimer, prothrombin time (PT), and the increase of platelet count (PLT) were of statistical significance (P<0.05). According to the results of the LASSO and multivariate logistic regression analyses, a model including preoperative portal vein diameter, preoperative portal blood flow velocity, postoperative D-dimer, and the increase of PLT was established to predict the risk of PVST after splenectomy. The model showed good accuracy with a C-index of 0.838 (95% CI: 0.750-0.926) and had a well-fitted calibration curve. Furthermore, internal validation showed it achieved a moderate C-index of 0.805. The DCA curve indicated that the model has clinical applicability when patients are treated at thresholds of 2-100%. CONCLUSIONS: Establishing a predictive model for the risk of PVST in patients with WD and hypersplenism after splenectomy can help clinicians identify patients at high risk of PVST who require intervention measures.

Efficacy and safety of heparin plus dexamethasone after partial splenic embolization for liver cirrhosis with massive splenomegaly.

PURPOSE: The aim of this study was to investigate the efficacy and safety of the combination of low-molecular-weight heparin + dexamethasone after partial splenic embolization in cirrhotic patients with massive splenomegaly. METHODS: This study included 116 patients with liver cirrhosis complicated with massive splenomegaly who underwent PSE in Union Hospital from January 2016 to December 2019, and they met the criteria. They were divided into two groups: PSE + Hep + Dex group (N = 54) and PSE group (N = 62). We conducted a retrospective study to analyze the efficacy and safety of the two groups of patients. RESULTS: The volume of splenic embolization was 622.34 ± 157.06 cm3 in the PSE + Hep + DEX group and 587.62 ± 175.33 cm3 in the PSE group (P = 0.306). There was no statistically difference in the embolization rate of the spleen between the two groups (P = 0.573). WBC peaked 1 week after PSE and PLT peaked 1 month after PSE in both groups; it gradually decreased later, but was significantly higher than the preoperative level during the 12-month follow-up period. The incidences of abdominal pain (46.3% vs 66.1%, P = 0.039), fever (38.9% vs 75.8%, P < 0.001), PVT (1.9% vs 12.9%, P = 0.026), refractory ascites (5.6% vs 19.4%, P = 0.027) were lower in the PSE + Hep + DEX group than in the PSE group. The VAS score of abdominal pain in PSE group was higher than that in PSE + Hep + DEX group on postoperative days 2-8 (P < 0.05). Splenic abscess occurred in 1(1.6%) patient in the PSE group and none (0.0%) in the PSE + Hep + DEX group (P = 0.349). CONCLUSIONS: The combined use of dexamethasone and low-molecular-weight heparin after PSE is a safe and effective treatment strategy that can significantly reduce the incidence of complications after PSE (such as post-embolization syndrome, PVT, refractory ascites).

Efficacy and safety of splenic artery embolization for intractable ascites using Amplatzer vascular plug versus coil after living donor liver transplantation.

PURPOSE Intractable ascites (IA) is an uncommon but challenging complication after liver transplantation. Splenic artery embolization (SAE) modulates the splenic artery and regulates portal flow. This study aimed to evaluate the efficacy and safety of SAE using the Amplatzer vascular plug (AVP) versus coil embolization for post-living-donor liver transplantation (LDLT) IA. METHODS This retrospective study evaluated consecutive patients from 1 center who received LDLT (n=1410) between March 2006 and August 2019. The inclusion criteria for SAE were splenomegaly with IA after LDLT. RESULTS Totally 15 patients underwent SAE for post-LDLT IA. Eleven patients who received AVP embolization (age, 51.2 ± 15.1 years; range, 8-63 years; 5 men and 6 women) were compared with 4 patients receiving coil embolization (age, 30.8 ± 30.8 years; range, 1.5-63 years; 2 men and 2 women). AVP and coil embolization both significantly reduced portal vein hyperflow (plug/ coil; P <.001/.006) and decreased ascites volume (plug/coil; P <.003/.042). The benefits of AVP embolization included shorter procedure time (P =.029), significantly reduced splenic volume (P =.012), increased liver volume (P =.012), decreased spleen/liver ratio (P =.012), and improvement of pancytopenia (P =.008) due to secondary hypersplenism. No significant differences were found between the two groups in the length of hospital stay or complications such as splenic infarction, pancreatitis, or sepsis. CONCLUSION SAE using AVP and coil embolization provide effective and safe methods for managing patients with IA after LDLT. AVP embolization may be more efficient than coil embolization, providing more effective reduction of ascites volume and the advantages of shortened procedure time and improvement of hypersplenism.

Determination of etiology in patients admitted due to isolated leukopenia.

Patients with isolated leukopenia pose difficulties in diagnosis because there is no related guideline in the literature. In this study, our aim was to evaluate the clinical and laboratory associations of isolated, nonspecific (not related to neutropenia) leukopenia. In this retrospective data review study, patients who were admitted to Hacettepe University Hematology Outpatient Clinic between 2014 and 2019 due to leukopenia were evaluated. The patients with anemia (other than iron deficiency) or thrombocytopenia were excluded. Clinical and laboratory data and the final diagnoses (if present) of the remaining cases and especially of those without neutropenia (the most difficult group to diagnose) were evaluated. One hundred sixty-nine patients were included in the study. One hundred forty-four (85.2%) patients were female and 25 (14.8%) were male. One hundred ten of them had 1500/µL or higher neutrophil count. In these nonneutropenic cases, the etiological factors contributing to leukopenia were as follows: iron deficiency anemia (21.8%), other autoimmune/autoinflammatory diseases (17.3%), autoimmune thyroid disease (21.8%), autoimmune laboratory tests (2.7%), drugs (12.7%), infection (5.5%), hematopoietic disorder (2.7%), hypersplenism (2.7%), radiotherapy sequel (1.8%), and B12 deficiency (1.8%). No etiology was recognized in 44 patients. On the other hand, the etiological factors in patients with neutrophil count <1500/µL were as follows; iron deficiency anemia (10.2%), other autoimmune/autoinflammatory diseases (17%), autoimmune thyroid disease (5.1%), autoimmune laboratory tests (8.5%), drugs (8.5%), infection (6.8%), hematopoietic disorder (11.9%), hypersplenism (1.7%), radiotherapy sequel (1.7%), and B12 deficiency (1.7%). No etiology was recognized in 25 patients. Physicians ordered bone marrow examination more frequently in patients with neutropenia. If isolated antinuclear antibody positivity was also considered in favor of autoimmunity, 91/169 (53.8%) cases had an autoimmune diagnosis or laboratory finding. In the present study, the most frequent reasons of isolated leukopenia in nonneutropenic patients are found as iron deficiency anemia, other autoimmune/autoinflammatory diseases, and autoimmune thyroid disease. In neutropenic patients, the most frequent reasons of isolated leukopenia are found as iron deficiency anemia, autoimmune/autoinflammatory diseases, and hematopoietic disorders. Therefore, autoimmunity is detected as an important factor leading to isolated leukopenia.

Early post-liver transplant thrombocytopenia in children: Clinical characteristics and significance.

BACKGROUND: Post-liver transplant thrombocytopenia is common and associated with worse outcome in adults. In children, however, the prevalence, course, and significance of post-liver transplantation thrombocytopenia are not described. Therefore, we aimed to assess this phenomenon in children. METHODS: A retrospective chart review of children who underwent liver transplantation at a single tertiary center between 2004 and 2021. RESULTS: Overall, 130 pediatric liver transplantations were reviewed. During the first 28 POD, thrombocytopenia was evident in 116 (89%, 95% CI 83%-94%). The median nadir platelet count was 54 K/µl (IQR: 37-99). Nadir platelet count was reached in half the patients by the third POD (IQR: 1-6). In multivariate analysis, preoperative platelet count (p = .024), volume of intraoperative packed cell transfusion (p = .045), and hypersplenism (p = .007) were associated with lower postoperative platelet counts. Patients with platelet count lower than the 50th centile on the first POD suffered from a more complicated course leading to a longer PICU admission (p = .039). CONCLUSIONS: Early post-liver transplant thrombocytopenia appears to be common in children and associated with preoperative thrombocytopenia, hypersplenism, and higher intraoperative blood transfusion volumes. A low first POD platelet count (<86 K/µl) was found to be independently associated with a more complicated postoperative course, suggesting the need for heightened surveillance.

Partial splenectomy in children undergoing liver transplantation or venous shunt for severe hypersplenism: A case control comparative study.

BACKGROUND AND AIM: Hypersplenism is a consequence of portal hypertension and splenomegaly secondary to cirrhosis or portal cavernoma in children. In order to avoid persistent hypersplenism and splenomegaly after liver transplantation (LT) or venous shunt (VS), partial splenectomy (PS) may represent a relevant therapeutic option. The aim of this retrospective study was to evaluate the results of PS performed in children presenting hypersplenism. METHODS: The following end-points were evaluated: (1) reversion of hypersplenism and its durability over time, (2) postoperative outcome, (3) courses of spleen size and volume and (4) comparison to a control group in which PS was not performed. RESULTS: Between 1996 and 2020, 16 children underwent PS associated with LT (8 cases) for cirrhosis or VS (8 cases) for portal cavernoma. From Day 0 to 1 month, mean platelet and white blood cell counts (WBC) dramatically improved from 48 ±â€¯19 at day 0 to 176 ±â€¯70 × 109/L (P < 0.0001) and from 2469 ±â€¯853 to 7198 ±â€¯3982/L (P = 0.001) respectively. PS allowed significant reduction of splenic length and volume from 176 ±â€¯33 to 112 ±â€¯24 cm (P < 0.0001) and from 1228 ±â€¯464 to 450 ±â€¯297 cm3 (P = 0.0003) respectively. After a mean follow-up of 92.6 ±â€¯84.7 months (range: 4.1-210.7), 14 patients are alive with normal platelet and WBC counts and persistent spleen size reduction. Compared to control group, PS was associated with a significant platelet count rise from baseline to one year. CONCLUSIONS: PS appears to be effective for treatment of hypersplenism and splenomegaly in combination with LT or VS without compromising outcome.

Robotic-assisted versus laparoscopic approach of Bai-Jiang-style vagus nerve-preserving splenectomy and azygoportal disconnection.

Robotic surgery has been widely accepted in many kinds of surgical procedures. Little is known about clinical effects of robotic-assisted splenectomy and azygoportal disconnection (RSD) for gastroesophageal variceal bleeding and secondary hypersplenism owing to cirrhotic portal hypertension. The aim of this study was to evaluate whether RSD is feasible and safe for patients with cirrhotic portal hypertension and whether RSD is superior to laparoscopic splenectomy and azygoportal disconnection (LSD). We retrospectively investigated the clinical effects of 50 patients with cirrhosis who underwent vagus nerve-preserving RSD (n = 20) and LSD (n = 30) between September 2020 and October 2021. We compared patients' demographic, intraoperative, and perioperative variables. RSD and LSD were successful in all patients. Operative time did not differ significantly between the RSD group and LSD group (151.15 ± 21.78 min vs. 144.50 ± 24.30 min, P > 0.05), but intraoperative blood loss were significantly reduced in the RSD group (61.00 ± 34.93 mL vs. 105.00 ± 68.77 mL, P < 0.05). No statistically significant differences were found regarding intraoperative allogeneic transfusion rate, visual analog scale pain score on the postoperative first day, time to first oral intake, initial passage of flatus, initial off-bed activity, postoperative hospital stay, and overall perioperative complication rate (all P > 0.05). In conclusion, RSD is not only a technically feasible and safe procedure but it was associated with less blood loss than LSD for cirrhotic portal hypertension with gastroesophageal variceal bleeding and secondary hypersplenism.

Effect of partial splenic embolization on transarterial chemoembolization for hepatocellular carcinoma with hypersplenism.

ABSTRACT: This study retrospectively studied transarterial chemoembolization (TACE) combined with partial splenic embolization (PSE) in the treatment of hepatocellular carcinoma (HCC) with severe hypersplenism.Seventy patients with HCC in Barcelona Clinic Liver Cancer (BCLC) stage B or C with hypersplenism were divided into non-partial splenic embolization group (N-PSE, n = 51) and partial splenic embolization group (PSE, n = 19). The N-PSE group was further divided into N-PSE with mild to moderate hypersplenism (N-PSE-M, 47 cases) and N-PSE with severe hypersplenism (N-PSE-S, 4 cases).In the PSE group, leukocytes, neutrophils, lymphocytes, and platelets were significantly increased (P < .05) and were significantly different from that in the N-PSE group (P < .05). In the N-PSE group, except for a slight increase in neutrophils, other blood cells were decreased, including lymphocytes that were significantly decreased (P < .05). There was no significant difference in the changes of liver function between the 2 groups before and after surgery (P > .05). The analysis showed a significant increase in ascites after 6 months of TACE in the N-PSE group (P < .05). According to the follow-up results, the median overall survival (OS) in the PSE group was 24.47 ±â€Š3.68 (months) and progression-free survival (PFS) was 12.63 ±â€Š4.98 (months). Regardless of OS or PFS, the PSE group was superior to the N-PSE group and its subgroups, with a statistically significant difference in PFS between the N-PSE group and PSE group (P < .05). Moreover, the time of extrahepatic progression was significantly earlier in the N-PSE group than in the PSE group (P < .05). N-PSE-S group had the worst prognosis, and PFS and OS were worse than the other 2 groups, suggesting that PSE in severe hypersplenism may improve PFS and OS.In patients with HCC and severe hypersplenism, TACE should be actively combined with PSE treatment.

Sorafenib plus partial splenic embolism for treatment of hepatocellular carcinoma Barcelona stage C combined with hypersplenism: a case series.

BACKGROUND: Sorafenib is mainly used to treat patients with hepatocellular carcinoma (HCC) Barcelona Clinic Liver Cancer (BCLC) stage C, many of whom also have severe cirrhosis. However, hypersplenism and digestive tract hemorrhage are common complications of cirrhosis, which increase the risk and difficulty of treatment. METHODS: Nineteen patients with HCC BCLC stage C with hypersplenism were treated with sorafenib plus partial splenic embolism at Chongqing University Cancer Hospital, Chongqing, China, between January 2015 and June 2018. We analyzed the therapeutic effect and clinical safety of this treatment in these patients. RESULT: Hypersplenism was rectified in all patients. The incidence rates of hemorrhage and myelosuppression were 0%, and the mean survival time was 11.2 months. CONCLUSION: Sorafenib plus partial splenic embolism could relieve hypersplenism and prolong survival in patients with BCLC stage C HCC.

Partial splenic embolization combined with endoscopic therapies and NSBB decreases the variceal rebleeding rate in cirrhosis patients with hypersplenism: a multicenter randomized controlled trial.

BACKGROUND: Global research on endoscopic therapies in combination with partial splenic embolization (PSE) for variceal hemorrhage (VH) is limited. Therefore, we aimed to evaluate the efficacy and safety of endoscopy plus PSE (EP) treatment in comparison to endoscopic (E) treatment for the secondary prophylaxis of VH in cirrhosis patients with hypersplenism. METHODS: Cirrhosis patients with hypersplenism (platelet count < 100, 000/µL) and those who had recovered from an episode of VH were enrolled in a multicenter randomized controlled trial. The participants were randomly assigned into EP and E groups in a 1:1 ratio. The primary endpoint was variceal rebleeding, and the secondary endpoints were severe variceal recurrence and mortality during the 2-year follow-up. Hematological indices, serum biochemical parameters, and the Child-Pugh score were measured at each time point. RESULTS: From June 2016 to December 2019, 108 patients were enrolled in the study, among which 102 patients completed the protocol (51 in EP and 51 in E group). The rebleeding rate of the varices was significantly reduced in the EP group compared to that in the E group during the 2 years (16% vs. 31%, p < 0.001). The EP group showed a significantly lower variceal recurrence rate than the E group (22% vs. 67%, p < 0.001). The COX proportional hazard models revealed that grouping was an independent predictor for variceal rebleeding (H = 0.122, 95% CI 0.055-0.270, p < 0.001) and variceal recurrence (hazard ratio, H = 0.160, 95% CI 0.077-0.332, p < 0.001). The peripheral blood cell count, Child-Pugh class/score, albumin concentration, and coagulation function in the EP group improved significantly compared to the values observed in the E group at any time point (p < 0.05). CONCLUSIONS: The EP treatment was more effective in preventing variceal rebleeding and variceal recurrence than the conventional E treatment during the secondary prophylaxis of VH in cirrhosis patients with hypersplenism. Furthermore, the EP treatment could significantly increase the peripheral blood cell count and albumin concentration and also improved the coagulation function and the Child-Pugh score.
