Comparative study of MAFLD as a predictor of metabolic disease treatment for NAFLD.

A novel concept of Metabolic Associated Fatty Liver Disease (MAFLD) was proposed, incorporating metabolic abnormalities such as obesity and diabetes, which are risk factors that affect the prognosis. Non-Alcoholic Fatty Liver Disease (NAFLD), entails fat accumulation in the liver without alcohol consumption and is often linked to obesity, insulin resistance, and metabolic syndrome. However, the broad nature of the disease concept has hindered prognosis accuracy. In this study, we assess the contribution of the impact of diagnostic criteria for MAFLD on metabolic disease progression compared to conventional diagnostic criteria for NAFLD. A total of 7159 patient who were presented to the health screening center in Tokai University Hospital both in 2015 and 2020 were included in the study. Fatty liver was diagnosed using abdominal ultrasonography. The diagnostic criteria for NAFLD were consistent with the global guidelines based on alcohol consumption. The diagnostic criteria for MAFLD were based on the International Consensus Panel. Medications (anti-hypertensive, diabetic, and dyslipidemia medications) were evaluated by self-administration in the submitted medical questionnaire. A total of 2500 (34.9%) participants were diagnosed with fatty liver (FL +), 1811 (72.4%) fit both NAFLD and MAFLD diagnostic criteria (overlap), 230 (9.2%) fit only the NAFLD diagnostic criteria (NAFLD group) and 404 (16.1%) fit the MAFLD diagnostic criteria (MAFLD group) at 2015. Over the next 5 years, medication rates increased in the NAFLD group for anti-hypertensive, + 17 (7.4%); diabetes, + 3 (1.3%); and dyslipidemia, + 32 (13.9%). In contrast, the only-MAFLD group showed a more significant increase with + 49 (12.1%), + 21 (5.2%), and + 49 (12.1%), for the respective medications, indicating a substantial rise in patients starting new medications. Our analysis of repeated health check-ups on participants revealed that the diagnostic criteria for MAFLD are more predictive of future treatment for metabolic disease than conventional diagnostic criteria for NAFLD.

Ectopic Adrenocorticotropic Hormone Syndrome due to Pancreatic Neuroendocrine Carcinoma: A Case Report.

A 55-year-old woman presented to her primary care physician with facial and lower leg edema. After being referred to our hospital because of hypothyroidism and hypokalemia on blood tests, she also had elevated adrenocorticotropic hormone (ACTH) and cortisol levels, but a dexamethasone suppression test showed no cortisol suppression. Ectopic ACTH syndrome due to pancreatic neuroendocrine carcinoma (PNEC) was suspected. endoscopic ultrasound-guided fine-needle aspiration was performed, and a histopathological examination of the obtained specimen revealed multiple liver metastases of the PNEC. Imaging after etoposide and cisplatin therapy showed cystic changes in the primary lesions and shrinkage of the liver metastases, and the ACTH levels were within the normal range.

Progression pattern and post-progression survival following atezolizumab and bevacizumab treatment in advanced hepatocellular carcinoma.

BACKGROUND: Although the combination of atezolizumab and bevacizumab (ATZ + BEV) is a standard treatment for advanced hepatocellular carcinoma (HCC), strategies for addressing treatment failure and prognostic factors of post-progression survival (PPS) remain unestablished. METHODS: We conducted a multicentre retrospective study to evaluate PPS following ATZ + BEV treatment in patients with advanced HCC. We classified the patients into three groups: BCLC stage B and BCLC stage C without or with new extrahepatic lesions (BCLCp-C1 and BCLCp-C2, respectively) at the time of progression. RESULTS: Of the 204 patients who started ATZ + BEV treatment between October 2020 and September 2022, 110 showed disease progression, with 33, 55 and 22 showing the BCLCp-B, BCLCp-C1 and BCLCp-C2 stages of the disease, respectively. Specifically, patients with the BCLCp-B stage of the disease showed better overall survival than those with the BCLCp-C1 and BCLCp-C2 stages (hazard ratios: 1.93 [95% confidence interval, CI, 1.06-3.51] and 2.64 [95% CI, 1.32-5.30] for HCC stages BCLCp-C1 and BCLCp-C2, respectively). Via multivariable analysis, we identified the BCLCp-C1 and BCLCp-C2 stages, as well as performance status, Child-Pugh class and alpha-fetoprotein as poor prognostic factors for PPS. CONCLUSIONS: BCLCp-B1 stage was identified as a better prognostic factor for PPS following ATZ + BEV treatment compared with BCLCp-C1 and BCLCp-C2 stages. This may help in making decisions regarding subsequent treatment after ATZ + BEV.

Low-grade Appendiceal Mucinous Neoplasm with Appendiceal Reduction and Re-expansion Over a Two-year Period: A Case Report.

A 71-year-old woman was found to have submucosal tumor-like lesion on colonoscopy (CS) before gastric surgery, and computed tomography (CT) showed a 12-mm structure at the base of the appendix. The lesion could not be clearly detected on CT nine months later, but it had enlarged again on CT one year later; therefore, CS and endoscopic ultrasound (EUS) were performed. The lesion was determined to be cystic with viscous contents, and laparoscopic appendicectomy was performed. This is the first report of low-grade appendiceal mucinous neoplasm (LAMN) diagnosed by a histopathologic examination of a resected specimen showing shrinkage and re-expansion of the appendix.

Impact of body composition for patients with hepatocellular carcinoma who received atezolizumab plus bevacizumab therapy.

OBJECTIVE: To investigate the association between body composition and prognosis in patients with advanced hepatocellular carcinoma treated with atezolizumab plus bevacizumab. METHODS: This cohort study analysed 119 patients who received atezolizumab plus bevacizumab for unresectable hepatocellular carcinoma. We investigated the association between body composition and progression-free survival and overall survival. Body composition was quantified by the visceral fat index, subcutaneous fat index, and skeletal muscle index. A high or low index score was defined as that above or below the median of these indices. RESULTS: Poor prognosis was observed in the low visceral fat index and low subcutaneous fat index groups. The mean progression-free survival in the low visceral fat index and low subcutaneous fat index groups vs. the other groups were 194 and 270 days, respectively [95% confidence interval (CI), 153-236 and 230-311 days, respectively; P = 0.015], while the mean overall survival was 349 vs. 422 days, respectively (95% CI, 302-396 and 387-458 days, respectively; P = 0.027). In the multivariate analysis, both a low subcutaneous fat index and low visceral fat index were statistically associated with lower progression-free and overall survival rates [hazard ratio (HR) 1.721; 95% CI, 1.101-2.688; P = 0.017; and HR 2.214; 95% CI, 1.207-4.184; P = 0.011, respectively]. CONCLUSION: Low visceral fat index and subcutaneous fat index scores were independent predictors of poor prognosis in patients with unresectable hepatocellular carcinoma treated with atezolizumab plus bevacizumab.

Association Between Immune-Related Adverse Events and Survival in Patients with Hepatocellular Carcinoma Treated With Atezolizumab Plus Bevacizumab.

BACKGROUND: Immune checkpoint inhibitors (ICIs) are effective for advanced hepatocellular carcinoma (HCC). However, there are few reports on the correlation between the clinical efficacy of ICIs and the development of immune-related adverse events (irAEs) in patients with HCC. The aim of this study was to investigate the association between irAE development and survival in patients with HCC treated with atezolizumab plus bevacizumab. PATIENTS AND METHODS: We enrolled 150 patients with advanced HCC treated with atezolizumab plus bevacizumab between October 2020 and October 2021 at 5 territorial institutions. We compared the efficacy of atezolizumab plus bevacizumab between patients who experienced irAEs (irAE group) and those who did not (non-irAE group). RESULTS: Thirty-two patients (21.3%) developed irAEs of any grade. Grade 3/4 irAEs were observed in 9 patients (6.0%). The median progression-free survivals (PFS) in the irAE and non-irAE groups were 273 and 189 days, respectively (P = .055). The median overall survivals (OS) in the irAE and non-irAE groups were not reached and 458 days, respectively (P = .036). Grade 1/2 irAEs significantly prolonged PFS (P = .014) and OS (P = .003). Grade 1/2 irAEs were significantly associated with PFS (hazard ratio [HR], 0.339; 95% confidence interval [CI], 0.166-0.691; P = .003) and OS (HR, 0.086; 95% CI, 0.012-0.641; P = .017) on multivariate analysis. CONCLUSION: The development of irAEs was associated with increased survival in a real-world population of patients with advanced HCC treated with atezolizumab plus bevacizumab. Grade 1/2 irAEs were strongly correlated with PFS and OS.

First reports of clinical effects of transjugular intrahepatic portosystemic shunt in four patients with cirrhotic ascites refractory to tolvaptan.

OBJECTIVE: Ascites in patients with decompensated cirrhosis can lead to abdominal distention and decrease quality of life. Tolvaptan, a vasopressin V2 receptor antagonist, is an effective agent in the treatment of ascites, whereas some patients are refractory to tolvaptan. The efficacy of transjugular intrahepatic portosystemic shunt (TIPS) for these patients is not known. In this study, we performed TIPS for tolvaptan-refractory cirrhotic patients and analysed its efficacy and safety in these patients. DESIGN: This retrospective analysis included patients with liver cirrhosis who received TIPS for ascites or hydrothorax refractory to tolvaptan therapy along with conventional diuretics between January 2015 and May 2018 at Tokai University Hospital. We evaluated the efficacy and safety of TIPS. RESULTS: This study included four patients. All patients presented with Child-Pugh class B liver cirrhosis and model for end-stage liver disease-sodium scores were 10/12/14/16. TIPS was generated successfully without any major complications in all patients. The body weight decreased by a mean of 4.7 (SD=1.0) kg and estimated glomerular filtration rate improved from a mean of 38.2 (SD=10.3) to 59.5 (SD=25.0) mL/min/1.73 m2 in a month after TIPS procedure. CONCLUSION: TIPS is an effective potential treatment for ascites in patients with tolvaptan refractory condition. In appropriate patients who can tolerate TIPS, the treatment may lead towards renal function improvement.

A case of breast cancer with extensive colon metastasis.

Breast cancer is one of the most common malignancies in women worldwide. Although most breast cancers are curable, in cases of metastasis, many are often found in the lungs, bones, liver, and central nervous system; however, metastasis to the gastrointestinal tract is rare. Invasive lobular carcinoma, which represents only 5%-10% of breast cancers, has a higher risk of metastasis to the gastrointestinal tract than invasive ductal carcinoma. Here, we report a rare case of gastrointestinal metastasis of invasive lobular carcinoma that spread extensively to the colonic mucosa. Given the improved survival rates of breast cancer patients with current treatments, many rarer metastatic diseases, including gastrointestinal metastases, are likely to be increased in the future.

Cell-free and concentrated ascites reinfusion therapy versus large-volume paracentesis for the treatment of cirrhotic patients with refractory ascites: A multicenter prospective observational study.

AIM: Cell-free and concentrated ascites reinfusion therapy (CART) and large-volume paracentesis (LVP) with albumin infusion are useful for managing refractory ascites (RA). However, it remains unclear which therapy is more effective in patients with cirrhosis with RA. METHODS: From June 2018 to March 2022, 25 patients with RA treated with CART or LVP with albumin infusion were enrolled in this multicenter prospective observational study to investigate the number of abdominal paracenteses, albumin preparations used, and drainage volume during an 8-week observation period. RESULTS: Among all patients at entry (median age, 63 years; 52% men; 60% Child-Pugh B and 40% Child-Pugh C), 92% were treated with furosemide (median, 20 mg/day), 92% with spironolactone (25 mg/day), and all with tolvaptan (7.5 mg/day). Patients with RA had a poor health-related quality of life (HRQOL) and prominent ascites-related symptoms. Four of the 20 eligible patients were treated with CART, 11 with LVP with albumin infusion, and five with their combination. The median number of paracenteses, total drainage volume, and albumin infusions were 1.5, 7.4 L, and 0, respectively, in the CART group; 5.0, 22.0 L, and 5.0, respectively, in the LVP group; and 5.0, 30.0 L, and 5.0, respectively in their combination group. The treatment effects did not differ significantly among the three groups regarding weight loss, liver function, renal function, electrolytes, and HRQOL. However, patients treated with CART had fewer paracenteses and albumin infusions than those treated with LVP. CONCLUSIONS: CART and LVP have comparable therapeutic efficacy for RA in patients with cirrhosis.

Clinical outcomes of antithrombin III-based therapy for patients with portal vein thrombosis: A retrospective, multicenter study.

AIM: The association between thrombolytic therapy and the outcome in patients with portal vein thrombosis (PVT) remains controversial. This study aimed to evaluate the outcome in patients with PVT who received antithrombin III-based therapy. METHODS: This study was a retrospective, multicenter study to investigate the liver-related events and the survival rates in 240 patients with PVT who received the therapy. RESULTS: The patients comprised 151 men and 89 women, with a median age of 69 years. The rate of favorable response, defined as maximum area of PVT changed to ≤75%, was 67.5% (162/240). The cumulative rates of liver-related events at 1, 2, and 3 years were 38.2%, 53.9%, and 68.5%, respectively. The multivariate analysis showed that viable hepatocellular carcinoma, absence of maintenance therapy, non-responder, and PVT progression were significantly associated with liver-related events. The PVT progression was observed in 23.3% (56/240). The multivariate analysis identified older age, absence of maintenance therapy, and non-responder as independent factors associated with PVT progression. The multivariate analysis revealed that younger age, no hepatocellular carcinoma, presence of maintenance therapy, and lower Model for End-stage Liver Disease-Sodium score significantly contributed to 3-year survival. Of the 240 patients, 13 (8.9%) prematurely discontinued treatment due to any adverse events. CONCLUSIONS: This study suggests that maintenance therapy, favorable response, and absence of PVT progression may suppress or control liver-related events in antithrombin III-based therapy for patients with PVT. Specifically, maintenance therapy could suppress not only liver-related events, but also PVT progression and improve the prognosis.

Antiviral Therapy for Patients Chronically Infected with Hepatis C Virus at Tokai University Hospital.

OBJECTIVE: Hepatitis C virus (HCV) was identified in 1989. In 2020, three decades after HCV identification, three researchers won the Nobel Prize in Physiology or Medicine for the discovery of this virus. In 1992, three years after the discovery, interferon (IFN) was launched as the first anti-HCV therapy in Japan; however, the efficacy of IFN therapy was far from acceptable due to severe adverse effects. The advent of IFN-free direct-acting antivirals (DAAs) in 2014 dramatically improved the outcomes of antiviral treatment without serious adverse effects. In this study, we aimed to summarize anti-HCV therapy at the Tokai University Hospital. METHODS: We identified patients who underwent anti-HCV therapy by searching medical records from January 1992 to December 2020, analyzed their background, and compared safety and efficacy among treatments. RESULTS: A total of 1777 treatments were given to 1299 patients. The sustained virologic response rate has dramatically increased over the past 30 years, with only 7% for IFN monotherapy and 95% or higher for recent IFN-free DAA therapies. CONCLUSIONS: We documented the results of anti-HCV therapy at the Tokai University Hospital. In the 30 years since the discovery of HCV, surprisingly successful progress has been accomplished in the anti-HCV treatment.

The prevalence and natural history of hepatic cysts examined by ultrasound: a health checkup population retrospective cohort study.

The prevalence of hepatic cysts in the general population and their natural history are largely unknown. This study aimed to assess the prevalence and natural history of hepatic cysts by investigating health checkup participants. Ultrasonographic data of health checkup participants (n = 38,842) were retrospectively evaluated to calculate its prevalence. In addition, we assessed the changes in the size and characteristics of hepatic cysts over 10 years (n = 7709). We found the prevalence of hepatic cysts was 21.9%. Older age, female sex, and presence of kidney cysts or pancreatic cysts were associated with the occurrence of hepatic cysts. Younger age, female sex, and the existence of multiple hepatic cysts were associated with cyst enlargement. Among 126 individuals who had hepatic cysts with a diameter of 30 mm or larger at the first visit, two (1.6%) required treatment. Remain 124 cases showed four patterns: 44 cases with enlargement, 47 stable, 11 regression after enlargement, and 22 regression. Hyperechoic fluid inside the cysts was observed in 54.5% (18 of 33), which was significantly higher than 6.6% (6 of 91) of the non-regression (OR = 17.0). The appearance of intracystic hyperechoic fluid by ultrasound may predict subsequent regression of the hepatic cyst.

Safety and efficacy of atezolizumab plus bevacizumab in patients with unresectable hepatocellular carcinoma in early clinical practice: A multicenter analysis.

PURPOSE: To assess the impact of clinical factors on the safety and efficacy of atezolizumab plus bevacizumab (ATZ + BV) treatment in patients with unresectable hepatocellular carcinoma (u-HCC). METHOD: Ninety-four u-HCC patients who were treated with ATZ + BV at multiple centers were enrolled. We defined Child-Pugh (CP)-A patients who received ATZ + BV treatment as a first line therapy as the 'meets the broad sense of the IMbrave150 criteria' group (B-IMbrave150-in, n = 46), and patients who received ATZ + BV treatment as a later line therapy or CP-B patients (regardless of whether ATZ + BV was a first line or later line therapy) as the B-IMbrave150-out group (n = 48). Patients were retrospectively analyzed for adverse events (AEs) and treatment outcomes according to their clinical characteristics, including neutrophil lymphocyte ratio (NLR) at baseline. RESULTS: The overall incidence of AEs was 87.2% (82/94 patients). The frequency of interruption of ATZ + BV treatment due to fatigue was higher in CP-B than CP-A patients (p = 0.030). Objective response (OR) rates of the B-IMbrave150-in group (28.3%, 39.1%) were significantly higher than those of the B-IMbrave150-out group (8.3%, 18.8%; p = 0.0157, 0.0401) using Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST, respectively. In multivariate analysis, NLR (hazard ratio (HR), 4.591; p = 0.0160) and B-IMbrave150 criteria (HR, 4.108; p = 0.0261) were independent factors associated with the OR of ATZ + BV treatment using RECIST. CONCLUSION: In real-world practice, ATZ + BV treatment might offer significant benefits in patients who meet B-IMbrave150 criteria or have low NLR.

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.

Lusutrombopag has slightly stronger effects on patients with mild thrombocytopenia compared with those with severe thrombocytopenia: A multicenter propensity score matching study.

BACKGROUND: Lusutrombopag effectively increases platelet count in patients with severe thrombocytopenia. However, no multicenter studies analyzing the effects of Lusutrombopag on patients with mild thrombocytopenia (platelet count > 50 000/µL) have been performed. In this study, we aimed to clarify the efficacy of Lusutrombopag on these patients by unifying background factors by propensity score matching. METHODS: A total of 139 patients with thrombocytopenia were enrolled, and matched for age, sex, etiology, disease, treatment, liver function, renal function, peripheral blood count, and spleen index. The primary endpoint was to compare the increase in platelet count from baseline between the high-platelet group (>50 000/µL) and the low-platelet group (<50 000/µL) after Lusutrombopag treatment, using propensity score matching. The secondary endpoint was to clarify platelet transfusion avoidance rate and adverse events, moreover, to identify independent predictors associated with the increase in platelet count. RESULTS: The mean increase in platelet count was 67 000/µL vs 48 000/µL in all patients (high- vs low-platelet group, P = .024), and 64 000/µL vs 48 000/µL (P = .12) after propensity score matching. The increase in platelet count and the platelet transfusion avoidance rate tended to be higher in the high-platelet group. There was no significant difference between adverse events. Predictors associated with an increase in platelet count were sex, estimated glomerular filtration rate, and spleen index by multivariate analysis. CONCLUSION: Lusutrombopag has a little stronger effect in patients with mild thrombocytopenia than those with severe thrombocytopenia and showed a more substantial effect in patients with impaired renal function and small spleen.

Impact of Anti-GPIIb/IIIa Antibody-Producing B Cells as a Predictor of the Response to Lusutrombopag in Thrombocytopenic Patients with Liver Disease.

BACKGROUND: To make an accurate estimate of the response to thrombopoietin (TPO) receptor agonists for thrombocytopenia associated with chronic liver disease, we evaluated the influence of antiplatelet autoantibodies on the response to lusutrombopag in thrombocytopenic patients with liver disease. METHODS: A prospective study was conducted at 2 hospitals. Thrombocytopenic patients with liver disease received oral lusutrombopag 3.0 mg once daily for up to 7 days. We analyzed changes in platelet counts from baseline to the maximum platelet count on days 9-14. The definition of clinical response was a platelet count of ≥5 × 104/µL with an increased platelet count of ≥2 × 104/µL from baseline. We assessed the correlation between the response to treatment drug and antiplatelet autoantibodies measured by anti-GPIIb/IIIa antibody-producing B cells. RESULTS: Thirty patients received the trial drug. There were 25 responders and 5 nonresponders. The median change in platelet counts was 3.9 × 104/µL (95% CI 2.8-4.6, p < 0.0001). The correlation between change in platelet counts and the frequency of the anti-glycoprotein IIb/IIIa antibody-producing B cells was moderate (r = 0.414, 95% CI 0.064-0.674, p = 0.023). In multivariate analysis of factors affecting the change in platelet counts, the anti-GPIIb/IIIa antibody-producing B cells were identified as an independent factor (regression coefficient [B] = 0.089; CI 0.021-0.157, p = 0.013). CONCLUSION: Anti-GPIIb/IIIa antibody-producing B cells may be a predictor for TPO receptor agonists in patients with chronic liver disease.

Case of hepatitis B virus reactivation after ibrutinib therapy in which the patient remained negative for hepatitis B surface antigens throughout the clinical course.

A 71-year-old man was diagnosed with B-cell chronic lymphocytic leukemia. He was negative for hepatitis B surface antigen (HBsAg), positive for antibodies against the hepatitis B surface and core, and negative for hepatitis B virus (HBV)-DNA before starting chemotherapy. A total of 13 months after the initiation of ibrutinib (a Bruton's tyrosine kinase inhibitor), the patient's alanine aminotransferase levels suddenly increased to 427 U/L. As the level of serum HBV-DNA increased to 5.2 logIU/mL, a diagnosis of HBV reactivation was made, whereas the patient remained negative for HBsAg. The patient's serum alanine aminotransferase levels normalized after the initiation of entecavir at a dose of 1 mg/day. However, it took >1 year to achieve an undetectable level of HBV-DNA, even with an add-on therapy of tenofovir disoproxil fumarate. Interestingly, the patient remained negative for HBsAg throughout the clinical course owing to triple HBsAg escape mutations: Q101K, M133L, and G145A.

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.

Nineteen-year prognosis in Japanese patients with biopsy-proven nonalcoholic fatty liver disease: Lean versus overweight patients.

BACKGROUND: Many studies have investigated the prognosis of nonalcoholic fatty liver disease (NAFLD); however, most studies had a relatively short follow-up. To elucidate the long-term outcome of NAFLD, we conducted a retrospective cohort study of patients with biopsy-proven NAFLD. METHODS: We re-evaluated 6080 patients who underwent liver biopsy from 1975 to 2012 and identified NAFLD patients without other etiologies. With follow-up these patients, we evaluated the outcome-associated factors. RESULTS: A total of 223 patients were enrolled, 167 (74.9%) was non-alcoholic steatohepatitis (NASH). The median follow-up was 19.5 (0.5-41.0) years and 4248.3 person-years. The risk of type 2 diabetes mellitus (T2DM) and hypertension was 11.7 (95% confidence interval [CI] 8.70-15.6) and 7.99 (95% CI 6.09-10.5) times higher, respectively, in NAFLD patients than in the general population. Twenty-three patients died, 22 of whom had NASH. Major causes of death were extrahepatic malignancy and cardiovascular disease (21.7%) followed by liver-related mortality (13.0%). All-cause mortality was significantly higher in NASH patients than in nonalcoholic fatty liver patients (P = 0.041). In multivariate analysis, older age (hazard ratio [HR] 1.09 [95% CI 1.05-1.14], P<0.001) and T2DM (HR 2.87 [95% CI 1.12-7.04], P = 0.021) were significantly associated with all-cause mortality. The factors significantly associated with liver-related events were older age, T2DM, milder hepatic steatosis, and advanced liver fibrosis. Body mass index wasn't associated with either mortality or liver-related events. CONCLUSIONS: T2DM was highly prevalent in NAFLD patients and was significantly associated with both all-cause mortality and liver-related events. The lean patients' prognosis wasn't necessarily better than that of overweight patients.

Hypothyroidism is a Predictive Factor for Better Clinical Outcomes in Patients with Advanced Hepatocellular Carcinoma Undergoing Lenvatinib Therapy.

Patients with advanced hepatocellular carcinoma (HCC) undergoing molecular targeted therapy often experience non-negligible adverse events (AEs). Paradoxically, certain AEs are reportedly associated with a good prognosis. We aimed to identify factors predictive of treatment duration and overall survival (OS) in patients with HCC undergoing lenvatinib therapy. Forty-six consecutive patients with advanced HCC who received lenvatinib therapy from April 2018 to November 2019 were prospectively followed until November 2019. Treatment efficacy was assessed according to the modified Response Evaluation Criteria in Solid Tumors for 2-3 months after therapy initiation. The disease control rate (DCR) was defined as the percentage of patients with a complete response, partial response, or stable disease. The DCR was 65.2%, with a median survival of 10.2 months. Grade 2/3 hypoalbuminemia resulted in shorter treatment duration. Factors predictive of longer OS were a Child-Pugh score of 5 at baseline and the occurrence of Grade 2/3 hypothyroidism. Conversely, Grade 2/3 hypoalbuminemia was associated with a poorer prognosis. An AE of Grade 2/3 hypothyroidism was associated with a better prognosis in patients receiving lenvatinib treatment for advanced HCC. Continuing anticancer therapy with appropriate thyroid hormone replacement may contribute to longer OS.
