The change rate in serum nitric oxide may affect lenvatinib therapy in hepatocellular carcinoma.

BACKGROUND: Lenvatinib is appropriate for reducing the production of nitric oxide (NO) and facilitating as block angiogenesis. However, to our knowledge, there are no data that support the correlation between NO and clinical response in patients who received lenvatinib therapy for HCC. Therefore, we investigated the correlation between the change rate of NO levels and clinical responses including adverse events (AEs) after lenvatinib therapy for unresectable hepatocellular carcinoma (HCC). METHODS: This study was conducted using previously collected data from another study. We enrolled 70 patients who received lenvatinib for advanced or unresectable HCC. NO was measured by converting nitrate (NO3-) to nitrite (NO2-) with nitrate reductase, followed by quantitation of NO2- based on Griess reagent. To determine whether lenvatinib influences NO in unresectable HCC, we evaluated the influence of the change rate of NO from baseline after administration of lenvatinib on maximal therapeutic response and SAE. RESULTS: After lenvatinib administration, a change rate in the NO from 0.27 to 4.16 was observed. There was no difference between the clinical response to lenvatinib and the change rate of NO (p = 0.632). However, the change rate of NO was significantly lower in patients with AEs than in those without AEs (p = 0.030). When a reduction in NO rate of < 0.8 was defined as a clinically significant reduction of NO (CSRN), the CSRN group had significantly worse progression-free survival (PFS) and overall survival (OS) than the non-CSRN group (p = 0.029 and p = 0.005, respectively). CONCLUSION: Decreased NO levels were associated with the occurrence of AEs and worse prognosis after lenvatinib administration. Change rate in serum NO can be used as predictive markers in patients receiving lenvatinib therapy for HCC.

A case of successful treatment with lenvatinib in primary hepatoid adenocarcinoma of the gallbladder that was difficult to distinguish from hepatocellular carcinoma.

Hepatoid adenocarcinoma (HAC) is an adenocarcinoma with components similar to those of hepatocellular carcinoma. Primary HAC of the gallbladder is extremely rare; to our knowledge, there is no consensus on the treatment after diagnosis. We reported an 82-year-old Japanese female of primary HAC of the gallbladder with postoperative recurrence that responded to lenvatinib. A total of 9 months has passed since the start of chemotherapy with lenvatinib, and the patient is in good general condition. To establish an effective treatment for primary HAC of the gallbladder, further accumulation and investigation of cases are recommended.

Evaluation of Skeletal Muscle Mass in Patients with Chronic Liver Disease Shows Different Results Based on Bioelectric Impedance Analysis and Computed Tomography.

OBJECTIVE: We aimed to evaluate the difference between computed tomography (CT)-based and bioelectrical impedance analysis (BIA)-based assessment of sarcopenia in patients with chronic liver disease (CLD). METHODS: We enrolled a total of 257 patients who were evaluated with or without sarcopenia. Sarcopenia was defined as a low skeletal muscle mass index (SMI) with low muscular strength by the Japan Society of Hepatology. To evaluate whether or not the different methods influence the diagnosis of sarcopenia for patients with CLD, we assessed the number and characteristics of mismatches between the low SMI using BIA and CT. We also compared the overall survival (OS) in patients with and without sarcopenia based on CT and BIA to evaluate the appropriate methods. RESULTS: The numbers of patients with low SMI using BIA or CT were 53 (20.6%) and 114 (44.3%) patients, respectively. Multivariate analysis revealed that hepatic ascites and body weight were independent factors of mismatch between SMI using BIA versus CT (hazard ratio [HR] 3.232, p < 0.001; HR 2.347, p = 0.005, respectively). The median OS in patients with sarcopenia based on CT was significantly lower than that in patients without sarcopenia (p = 0.006). In contrast, there was no difference between patients with sarcopenia based on BIA (p = 0.217). CONCLUSION: Muscle mass in patients with CLD may be overestimated by the BIA method compared to CT when assessing sarcopenia, especially in cases of fluid retention.

Additional L-Carnitine Reduced the Risk of Hospitalization in Patients with Overt Hepatic Encephalopathy on Rifaximin.

BACKGROUND: Data regarding the additional effect on the recurrence of hepatic encephalopathy (HE) after oral L-carnitine administration are scarce. OBJECTIVE: This study aimed to assess the additional effects of L-carnitine in patients who were receiving rifaximin for HE. METHODS: This randomized study comprised a screening visit and a 12-week treatment period. Patients who fulfilled the eligibility criteria were randomized to either group A (additional rifaximin) or group B (additional L-carnitine and rifaximin). Group A received 1,200 mg/day of rifaximin. Group B received 1,500 mg/day of L-carnitine and rifaximin at 1,200 mg/day. The endpoints were the changes in the portal systemic encephalopathy (PSE) index and the admission rate from the baseline for the duration of the study in both groups. RESULTS: Eighty-three patients were randomized to either group A (n = 42) or group B (n = 41). In group A, the PSE index decreased from 0.35 ± 0.09 at baseline to 0.27 ± 0.11 on the final evaluation day (p = 0.001). In group B, the PSE index decreased from 0.37 ± 0.09 at baseline to 0.24 ± 0.11 on the final evaluation day (p = 0.001). Although there was not a significant reduction in the PSE index in group A compared to that in group B (p = 0.202), the admission rates were 30.9% and 9.8% in groups A and B, respectively. Additional L-carnitine significantly reduced the admission rate (p = 0.028). CONCLUSION: L-Carnitine addition reduced the risk of hospitalization for patients who received rifaximin for HE.

Splenectomy for Torsion of a Wandering Spleen in a Patient with Myeloproliferative Disease.

We herein report a rare case of torsion of a wandering spleen in a patient with myeloproliferative disease. A 66-year-old Japanese woman presented to our hospital with abdominal pain and a fever. She had a medical history of polycythemia and secondary myelofibrosis. Abdominal enhanced computed tomography showed an enlarged spleen without enhancement in the lower pelvic region. The clinical diagnosis was severe torsion of a wandering spleen in a patient with myeloproliferative disease, necessitating surgical intervention. Splenectomy was performed after de-rotating to revascularize the spleen. After the operation, the platelet count gradually increased, and aspirin was administered to prevent thrombosis.

The Risk of Cirrhosis and Its Complications Based on PNPLA3 rs738409 G Allele Frequency.

BACKGROUND: Data regarding the influence of patatin-like phospholipase domain-containing 3 (PNPLA3) polymorphism for patients with liver cirrhosis (LC) are scarce. OBJECTIVE: This study assesses the role of the PNPLA3 polymorphism for the development of LC and its complications by the findings of genetic examinations. METHODS: Patients with LC caused by virus (n = 157), alcohol (n = 104), nonalcoholic fatty liver disease (NAFLD) (n = 106), or autoimmune disease (n = 33) and without LC (n = 128) were enrolled. LC was composed of the presence and absence of complications, such as variceal bleeding, hepatic ascites, and hepatic encephalopathy. To assess the role of the PNPLA3 polymorphism, odds ratio (OR) for the rs738409 variant was calculated for the patients between (i) with LC and without LC in the entire cohort and (ii) the presence and absence of complications in the patients with LC. RESULTS: There was a significant difference among the patients without LC and those with alcohol, NAFLD-related LC in the frequency of G alleles (p < 0.001, both). According to complications of LC, the OR for NAFLD-related cirrhosis significantly increased in the presence of the two mutated alleles (OR = 3.165; p = 0.046) when the wild type was used as the reference. However, there were no significant risks for the complications in the virus and alcohol-related cirrhosis unless there was a presence of G alleles. CONCLUSION: The PNPLA3 polymorphism was associated with the risk of NAFLD-related LC and its complications.

Prospective study for an independent predictor of prognosis in liver cirrhosis based on the new sarcopenia criteria produced by the Japan Society of Hepatology.

AIM: There are limited data from prospective studies showing the clinical usefulness of the new criteria for sarcopenia in liver disease produced by the Japan Society of Hepatology. Therefore, we aimed to evaluate the clinical usefulness of this new criteria for prognosis in cirrhotic patients. METHODS: This prospective study was performed at six centers. The 300 enrolled patients, aged more than 20 years with liver cirrhosis, were evaluated over a 3-year period for skeletal muscle mass index and grip strength. Sarcopenia was defined according to the Japan Society of Hepatology criteria by grip strength and computed tomography-based skeletal muscle mass index values. We investigated the correlation between sarcopenia and the survival rate of cirrhotic patients. RESULTS: Among the 300 assessed patients there were 99 (33%) patients with sarcopenia. The number of deaths in the sarcopenia and non-sarcopenia groups was 34 (34.3%) and 38 (18.9%), respectively (p = 0.002). Multivariate analysis confirmed that sarcopenia, decompensated phase, albumin-bilirubin grade, and hepatocellular carcinoma (HCC) stage 3/4 were independent factors correlated with death in patients with liver cirrhosis during the observation period. The interaction between sarcopenia and the presence of HCC was statistically significant (p < 0.001), and the presence of HCC had the highest hazard ratio of 6.665 for deaths in cirrhotic patients when non-sarcopenia and the absence of HCC were used as references. CONCLUSIONS: The new Japan Society of Hepatology criteria for sarcopenia are accurate predictors of poor prognosis in patients with liver cirrhosis.

A case of immune checkpoint inhibitor-associated myocarditis after initiation of atezolizumab plus bevacizumab therapy for advanced hepatocellular carcinoma.

In November 2020, atezolizumab plus bevacizumab became available for the treatment of hepatocellular carcinoma (HCC), and its efficacy is expected as a new treatment option for HCC. However, the occurrence of immune-related adverse events (irAEs) associated with the administration of immune checkpoint inhibitors is a major concern in clinical practice. We reported a case of irAE-induced myocarditis after the treatment for HCC. Based on the symptoms and echocardiographic findings, we suspected irAE-induced myocarditis and acute heart failure, and the patient was admitted to the hospital for further investigation and treatment. From starting the patient on therapy with methylprednisolone succinate sodium, the laboratory data and symptoms tended to improve. The patient was discharged to home on the 25th day of treatment. Because the number of patients with irAE myocarditis is expected to increase in clinical practice in the near future, further accumulation and investigation of cases are necessary.

Cartilage-hair Hypoplasia Complicated with Liver Cirrhosis Due to Chronic Intrahepatic Cholestasis.

We herein report a rare case of cartilage-hair hypoplasia (CHH) complicated with liver cirrhosis. A 20-year-old Japanese man with CHH was found incidentally to have liver cirrhosis and an esophageal varix. This patient had been treated for infections due to immunodeficiency since early childhood. He ultimately died of liver failure at 31 years of age. An autopsy revealed an abnormality of the interlobular bile ducts and intrahepatic cholestasis. Liver cirrhosis was thought to have been caused by chronic intrahepatic cholestasis due to biliary duct hypoplasia and changes in the intestinal microbiome. Therefore, CHH may cause biliary cirrhosis due to multiple effects.

Clinicopathological Features of Autoimmune Hepatitis with IgG4-Positive Plasma Cell Infiltration.

BACKGROUND: We aimed to elucidate the characteristics and prognosis of autoimmune hepatitis (AIH) patients with immunoglobulin (Ig) G4-positive plasma cell infiltration. METHODS: We enrolled 84 AIH patients. The number of IgG- and IgG4-positive plasma cells was immunohistochemically counted per high-power field in the portal area. Patients with 3 or more IgG4-positive plasma cells on average and a ratio of IgG4 to IgG-positive plasma cells ≥5% were defined as IgG4-associated AIH (IgG4-AIH), and their clinicopathological characteristics and prognosis were compared to those of the remaining classical-AIH patients. RESULTS: Ten (11.9%) and 74 patients (88.1%) were categorized as IgG4-AIH and classical-AIH patients, respectively. The median age of the IgG4-AIH patients was 67 years, the majority was female (80.0%), and the distribution was similar to that of the classical-AIH patients. The IgG4-AIH patients exhibited significantly more severe phenotypes in portal inflammation, interface hepatitis, fibrosis, and rosette formation. All clinical laboratory data were similar except for serum IgG4 levels, which were higher in IgG4-AIH patients (168.5 vs. 22.9 mg/dL, p = 0.014). During a median follow-up period of 139 months, the relapse rate was significantly lower in the IgG4-AIH group than in the classical-AIH group (11.1 vs. 49.2%; p = 0.048). Twelve (16.2%) and 6 (8.1%) classical-AIH patients underwent liver-related events and liver-related deaths, respectively. In contrast, none of the IgG4-AIH patients progressed to severe liver disease. CONCLUSIONS: The IgG4-AIH patients had more severe inflammation and advanced fibrosis in the liver. However, their prognosis was not poor compared to that of classical-AIH patients. IgG4-AIH may have a phenotype distinct from classical-AIH.

Safety and Efficacy of Lenvatinib Treatment in Child-Pugh A and B Patients with Unresectable Hepatocellular Carcinoma in Clinical Practice: A Multicenter Analysis.

PURPOSE: To assess the safety, efficacy and prognostic impact of clinical factors related to lenvatinib treatment in Child-Pugh class A (CP-A) and class B (CP-B) patients with unresectable hepatocellular carcinoma (u-HCC). METHODS: Patients with u-HCC who were treated with lenvatinib at multiple centers in Japan were retrospectively analyzed for treatment outcomes according to their respective CP status. Radiological objective response (OR) was assessed using modified response evaluation criteria in solid tumors (mRECIST) guidelines. RESULTS: Baseline demographic parameters were comparable between 126 (69.6%) patients with CP-A disease and 55 patients (30.4%) with CP-B disease. Frequency of lenvatinib-related adverse events, including decreased appetite (P=0.034), diarrhea (P=0.040), elevated serum bilirubin (P=0.016) and vomiting (P=0.009), were higher in CP-B than in CP-A patients. Relative dose intensity (RDI) was significantly higher in CP-A (0.69) than CP-B patients (0.50, P <0.001). Furthermore, OR rate (44.0%) was markedly higher in CP-A5 patients as compared to CP-A6 (25.5%), CP-B7 (22.2%), and CP-B8 patients (5.3%), respectively (P=0.002). In multivariable analysis, performance status (0 vs 1, 2, P=0.026), CP class (A vs B, P=0.045) and RDI (≥0.7 vs <0.7, P=0.034) were identified as factors associated with response to lenvatinib treatment. Overall survival (OS) at 12 months was significantly different between CP-A (66.3%) and CP-B patients (30.0%, P=0.002), and between CP 5-7 (59.2%) and CP 8 patients (34.8%, P=0.003). In multivariable analysis, CP class (A vs B, P=0.007) and Barcelona clinic liver cancer (BCLC) stage (B vs C, P=0.002) were associated with OS following lenvatinib treatment. CONCLUSION: Lenvatinib treatment offers significant benefits in patients with good liver function in real-world practice. The various characteristics identified in this study might be helpful as clinical predictors of response to lenvatinib and survival in clinical practice. Further studies are required to address eligibility for lenvatinib treatment in CP 7 patients.

Influence of NOS3 rs2070744 genotypes on hepatocellular carcinoma patients treated with lenvatinib.

We investigated whether or not nitric oxide synthase 3 (NOS3) rs2070744 genotypes can affect the response for lenvatinib treatment in patients with hepatocellular carcinoma (HCC). We evaluated the relation of the NOS3 rs2070744 genotypes to the tumor response, progression-free survival (PFS), and overall survival (OS) as the response for lenvatinib. We also examined the association between fibroblast growth factor receptor (FGFR) gene polymorphisms, a potential feature of lenvatinib, and the response. There were no significant differences between the studies for either PFS or OS, even though patients with the TT genotype had a longer mean PFS (hazard ratio [HR] 0.60; p = 0.069) and mean OS (HR 0.46; p = 0.075) than those with the TC/CC genotypes. However, patients with a single-nucleotide polymorphism (SNP) combination pattern of the NOS3 rs2070744 TC/CC and FGFR4 rs351855 CT/TT genotypes had a significantly shorter mean PFS (HR 2.56; p = 0.006) and mean OS (HR 3.36; p = 0.013) than those with the other genotypes. The NOS3 rs2070744 genotypes did not influence the clinical response. However, the SNP combination pattern of the NOS3 rs2070744 and FGFR4 rs351855 genotypes may be helpful as treatment effect predictors and prognostic factors for HCC patients treated with lenvatinib.

Long-term observation in patients with esophageal varices after endoscopic variceal ligation accompanied with 24-hour pH monitoring.

AIM: Esophageal variceal ligation (EVL) is usually carried out to decrease the risk of hemorrhage. Several complications have been reported with the procedure, including bleeding from ligation-induced esophageal ulcers or heartburn. However, there is scant evidence for gastroesophageal reflux caused by EVL. The aim of this study was to assess 24-h pH monitoring in the esophagogastric junction before and after EVL and the bleeding rate for 18 months. METHODS: We undertook this single-center prospective trial in Kitasato University Hospital (Sagamihara, Japan). We included patients with cirrhosis who were Child-Pugh classification A or B, without uncontrollable hepatocellular carcinoma, and had F2 or larger esophageal varices, and/or were red color sign (RC) positive. The study period was from July 2012 through September 2017 for 32 patients enrolled in this study and followed up until March 2019. RESULTS: Baseline characteristics were: median Child-Pugh score, 6; and mean age, 64.3 years. Before and after EVL, the median 24-h under pH 4 holding time percentages of all patients were 0.6% (range, 0-5.6%) and 0.95% (range, 0-50.6%), respectively, without a significant difference (P = 0.107). We could not find any G3 or G4 adverse events during this study, and 75% of the patients who had already suffered from moderate gastroesophageal reflux became worse after EVL (P = 0.18) and required antacid therapies. There were no patients with hemorrhage from esophageal varices. CONCLUSIONS: Esophageal variceal ligation for esophageal varices did not significantly change gastroesophageal reflux. Therefore, acid suppressive therapy might be unnecessary for patients who do not suffer from gastroesophageal reflux after EVL.

Undifferentiated Embryonal Sarcoma of the Liver Identified after the Initial Diagnosis of a Hepatic Cyst.

Abdominal ultrasound in a 50-year-old Japanese man revealed a cystic lesion on the caudate lobe of the liver. Four-month follow-up imaging showed a rapid increase in the size of the cystic lesion. The patient underwent laparoscopic partial hepatectomy because of a suspicion and perceived risk that the lesion might be malignant. The initial histological diagnosis was a hepatic cyst. Eleven months later, computed tomography showed a giant cystic lesion in the abdominal cavity and multiple liver metastases. The patient underwent excision of the giant cystic lesion and a partial hepatectomy. Immunohistochemistry for the recurring lesion revealed undifferentiated embryonal sarcoma of the liver.

Portal hemodynamic effects of lenvatinib in patients with advanced hepatocellular carcinoma: A prospective cohort study.

AIM: Lenvatinib is an oral, multitargeted, tyrosine kinase inhibitor, which suppress tumor angiogenesis and tumor progression. It was non-inferior to sorafenib in overall survival in untreated advanced hepatocellular carcinoma (HCC). Sorafenib had a beneficial effect on portocollateral circulation with portal hypertension in translating and clinical studies. However, the hemodynamic effects of lenvatinib appear to be different from those of sorafenib because the efficacy of lenvatinib for vascular endothelial growth factor receptors and fibroblast growth factor receptors is different from that of sorafenib. This study was prospectively performed to evaluate the portal hemodynamic effect of lenvatinib in patients with advanced HCC using duplex Doppler ultrasonography. METHODS: In total, 28 Child-Pugh class A or B patients with advanced HCC received lenvatinib depending on body weight daily for 2 weeks. Primary outcomes were changes in the hemodynamics of the portal venous system using duplex Doppler ultrasonography before and after the 2-week administration of lenvatinib. RESULTS: The portal venous flow velocity (cm/s) significantly reduced (27 ± 12.1 vs. 22.6 ± 8.0, P = 0.019), while portal venous area (cm2 ) did not change after the 2-week administration (0.80 ± 0.36 vs. 0.82 ± 0.27, P = 0.665). Therefore, the congestion index (portal venous area/portal venous flow velocity), which reflects the pathophysiological hemodynamics of the portal venous system significantly worsened (0.037 ± 0.025 vs. 0.043 ± 0.024, P = 0.045). CONCLUSIONS: Considering that this was a short-term study, because lenvatinib could be an agent that aggravates portal hypertension, it will be necessary to verify its clinical effects for portal hypertension in future studies.

Skeletal Muscle Mass Influences Tolerability and Prognosis in Hepatocellular Carcinoma Patients Treated with Lenvatinib.

BACKGROUND: Low skeletal muscle mass is significantly associated with severe adverse events (AEs) from chemotherapy, and low tolerability leads to decreased survival. We aimed to investigate whether body skeletal muscle mass is correlated with tolerability and prognosis in patients with hepatocellular carcinoma (HCC) treated with lenvatinib. METHODS: This multicenter, retrospective study was conducted at five locations in Japan. We included 100 patients with HCC treated with lenvatinib. Skeletal muscle mass was measured by computed tomography and normalized for height in m2 as skeletal muscle index (SMI). The assessment criteria for low SMI were taken from the sarcopenia criteria of the Japan Society of Hepatology. We investigated the influence of low SMI on drug withdrawal due to severe AEs in the first 2 months and on time to treatment failure (TTF) and overall survival (OS). RESULTS: The numbers of high- and low-SMI patients were 41 and 59, respectively. Those with severe AEs leading to withdraw in the high- and low-SMI groups were 7 and 23, respectively. The low-SMI group had a higher withdrawal rate than the high-SMI group (p = 0.042). The median TTF in the low- and high-SMI groups was 139 and 230 days, respectively. The median OS in the low- and high-SMI groups was 264 and 353 days, respectively. Patients in the low-SMI group experienced significantly worse OS and TTF than those in the high-SMI group (log-rank test for trend: TTF, p = 0.010; OS, p = 0.021). CONCLUSION: Decreased skeletal muscle mass is associated with the occurrence of severe AEs and worse TTF and OS. Skeletal muscle mass can be used as a predictive marker for tolerability and prognosis to lenvatinib in patients with HCC.

Early Changes in Circulating FGF19 and Ang-2 Levels as Possible Predictive Biomarkers of Clinical Response to Lenvatinib Therapy in Hepatocellular Carcinoma.

Predictive biomarkers of the response of hepatocellular carcinoma (HCC) to Lenvatinib therapy have not yet been clarified. The aim of this study was to identify clinically significant biomarkers of response to Lenvatinib therapy, to target strategies against HCC. Levels of circulating angiogenic factors (CAFs) were analyzed in blood samples collected at baseline and after introducing lenvatinib, from 74 Child-Pugh class A HCC patients who received lenvatinib. As CAF biomarkers, serum vascular endothelial growth factor (VEGF), fibroblast growth factor 19 (FGF19), FGF23, and angiopoietin-2 (Ang-2) were measured using enzyme-linked immunosorbent assays. Results: Significantly increased FGF19 (FGF19-i) levels and decreased Ang-2 (Ang-2-d) levels were seen in Lenvatinib responders as compared to non-responders (ratio of FGF19 level at 4 weeks/baseline in responders vs. non-responders: 2.09 vs. 1.32, respectively, p = 0.0004; ratio of Ang-2 level at four weeks/baseline: 0.584 vs. 0.810, respectively, p = 0.0002). Changes in FGF23 and VEGF levels at four weeks versus baseline, however, were not significantly different in responders versus non-responders. In multivariate analysis, the combination of serum FGF19-i and Ang-2-d was the most independent predictive factor for Lenvatinib response (Odds ratio, 9.143; p = 0.0012). Furthermore, this combination biomarker showed the greatest independent association with progression-free survival (Hazard ratio, 0.171; p = 0.0240). Early changes in circulating FGF19 and Ang-2 levels might be useful for predicting clinical response and progression-free survival in HCC patients on Lenvatinib therapy.

Usefulness of autotaxin for the complications of liver cirrhosis.

BACKGROUND: Autotaxin (ATX) has been reported as a direct biomarker for estimating the evaluation of liver fibrosis. But available data on ATX as a useful biomarker for the complications of liver cirrhosis (LC) are scant. AIM: To assess the clinical usefulness of ATX for assessing the complications of LC. METHODS: This multicenter, retrospective study was conducted at six locations in Japan. We include patients with LC, n = 400. The ATX level was evaluated separately in men and women because of its high level in female patients. To assess the clinical usefulness of ATX for the complications of LC, the area under the curve (AUC) of ATX assessing for the severe complications was analyzed in comparison with the model for end-stage liver disease score, albumin-bilirubin (ALBI) score, fibrosis-4 index, and aspartate aminotransferase-to-platelet ratio index. RESULTS: The mean age was 68.4 ± 11.4 years, 240 patients (60.0%) were male. A total of 213 (53.3%) and 187 (46.8%) patients were compensated and decompensated, respectively. The numbers of patients with varix rupture, hepatic ascites, and hepatic encephalopathy were 35 (8.8%), 131 (32.8%), and 103 (25.8%), respectively. The AUCs of ATX in men for hepatic encephalopathy, hepatic ascites, and varix ruptures were 0.853, 0.816, and 0.706, respectively. The AUCs of ATX in women for hepatic encephalopathy, hepatic ascites, and varix rupture were 0.759, 0.717, and 0.697, respectively. The AUCs of ATX in men were higher than those in women, as were all the other biomarkers used to detect encephalopathy and varix ruptures. However, for detecting ascites, the AUC of ALBI in men was more effective than using ATX. CONCLUSION: ATX in men was more effective than any other biomarkers for detecting hepatic encephalopathy and varix ruptures.

Furosemide Dose Changes Associated with Furosemide/Tolvaptan Combination Therapy in Patients with Cirrhosis.

BACKGROUND: Few data have demonstrated that the combination therapy comprising a natriuretic drug and an aquaretic drug has improved renal function compared with the conventional diuretic therapy of only a natriuretic drug in patients with cirrhosis. OBJECTIVE: This study aimed to assess the influence to the renal function by furosemide dose reductions after administration of tolvaptan in cirrhotic ascites patients. METHODS: A 2-center, open-label, randomized study with a 24-week treatment period was conducted in Japan. Patients who met the study's criteria were randomized to a conventional therapy group or a combination therapy group in a 1:1 ratio. The combination therapy group received tolvaptan and reduced furosemide doses compared with those received before the study enrollment. The conventional therapy group continued with the original dosage regimens. We assessed the change in estimated glomerular filtration rate (eGFR) from baseline through the duration of the study in the 2 groups. RESULTS: Twenty-nine patients were randomized to receive either the combination therapy group (n = 14) or the conventional therapy group (n= 15). The change in the furosemide dose from baseline was -35.2 ± 10.1 mg in the combination therapy group. After 24 weeks of treatment, significantly greater improvement in eGFR was observed in the combination therapy group (2.4 ± 0.4 mL/min 1.73 m2) compared with those in the conventional therapy group (-5.1 ± 1.2 mL/min 1.73 m2; p = 0.013). CONCLUSION: A combination therapy of tolvaptan and furosemide enabled furosemide dose reductions. Systematic reductions of the furosemide doses can lead to the improvement of renal function.
