Simple Scoring System for Esophagogastric Varices Prediction in Hepatocellular Carcinoma Patients without Liver Stiffness Evaluation.

INTRODUCTION: For predicting esophagogastric varices (EGVs), the Virtual Baveno VII Consensus Workshop has proposed a combination of liver stiffness determination and platelet count measurement using a FibroScan®. However, FibroScan® is not available at all institutions. The present study aimed to develop a simple method to predict development of EGV using only general blood examination results. MATERIALS AND METHODS: A total of 1,090 hepatocellular carcinoma patients were enrolled, after excluding 956 with major portal vein tumor thrombus (Vp3/Vp4) or without upper gastrointestinal endoscopy examination results available. Those with EGV (≥ grade F2) or a history of treatment for the condition were defined as positive for significant EGV, and then clinical factors were retrospectively evaluated to determine indicators of occurrence. RESULTS: Logistic multivariate analysis showed platelet count (≤12 × 104/µL) (odds ratio [OR] 3.79, p < 0.001), mALBI grade 2a (OR 1.52, p = 0.036), and mALBI 2b or 3 (OR 3.46, p < 0.001) as significant predictive factors. Based on the OR values, platelet count (≤12 × 104/µL) and mALBI grade 2b/3 were each assigned 2 points and mALBI 2a was given 1 point, with the result termed recommendation for EGV screening (REGS) score. Significant EGV occurrence was noted in 2.9% (9/311) of the patients with a REGS score 0, 11.0% (13/118) with a score 1, 19.3% (53/274) with a score 2, 29.5% (39/132) with a score 3, and 38.0% (97/255) with a score 4 (p < 0.001). CONCLUSION: The findings indicate that REGS score can provide useful predictive information for development of significant EGV without the need for special equipment such as a FibroScan®.

Functional AGXT2 SNP rs180749 variant and depressive symptoms: Baseline data from the Aidai Cohort Study in Japan.

No study has shown the relationship between alanine-glyoxylate aminotransferase 2 (AGXT2) single nucleotide polymorphisms (SNPs) and depressive symptoms. The present case-control study examined this relationship in Japanese adults. Cases and control participants were selected from those who participated in the baseline survey of the Aidai Cohort Study, which is an ongoing cohort study. Cases comprised 280 participants with depressive symptoms based on a Center for Epidemiologic Studies Depression Scale (CES-D) score ≥ 16. Control participants comprised 2034 participants without depressive symptoms based on the CES-D who had not been diagnosed by a physician as having depression or who had not been currently taking medication for depression. Adjustment was made for age, sex, smoking status, alcohol consumption, leisure time physical activity, education, body mass index, hypertension, dyslipidemia, and diabetes mellitus. Compared with the GG genotype of rs180749, both the GA and AA genotypes were significantly positively associated with the risk of depressive symptoms assessed by the CES-D: the adjusted odds ratios for the GA and AA genotypes were 2.83 (95% confidence interval [CI] 1.23-8.24) and 3.10 (95% CI 1.37-8.92), respectively. The TGC haplotype of rs37370, rs180749, and rs16899974 was significantly inversely related to depressive symptoms (crude OR 0.67; 95% CI 0.49-0.90), whereas the TAC haplotype was significantly positively associated with depressive symptoms (crude OR 1.24; 95% CI 1.01-1.52). This is the first study to show significant associations between AGXT2 SNP rs180749, the TGC haplotype, and the TAC haplotype and depressive symptoms.

Combined effect of histological findings and diabetes mellitus on liver-related events in patients with metabolic dysfunction-associated steatotic liver disease.

AIM: Advanced fibrosis has a strong influence on the occurrence of liver-related events in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), while diabetes mellitus (DM), which is often complicated by MASLD, is associated with the progression of MASLD. We stratified patients with MASLD according to the severity of liver pathological findings and the presence of DM, aiming to examine whether these indices could be used to accurately assess the risk of developing liver-related events. METHODS: A total of 282 patients with liver biopsy-proven MASLD were included. Liver-related events were defined as the occurrence of hepatocellular carcinoma (HCC) and complications of liver cirrhosis, such as ascites, hepatic encephalopathy, Child-Pugh class B and C, as well as treatment-eligible esophageal and gastric varices. RESULTS: Multivariate analysis adjusted for age, sex, body mass index, alanine aminotransferase, creatinine, hemoglobin A1c, smoking habits, dyslipidemia, hypertension, nonalcoholic fatty liver disease activity score (NAS), or fibrosis stage showed that advanced fibrosis with or without DM was a risk factor for liver-related events. The combined effect of DM and advanced fibrosis increased the risk of HCC onset. However, DM alone or in combination with NAS did not affect the development of liver-related events, including the occurrence of HCC and complications of liver cirrhosis. CONCLUSIONS: While the assessment of fibrosis in patients with MASLD is important for evaluating the risk of developing liver-related events, combining the assessment of DM may be possible to stratify groups at higher risk of developing HCC.

Changes in characteristics of gastroenterology center inpatients in Japan because of rapidly aging society.

BACKGROUND AND AIM: Rapidly aging societies have become a major issue worldwide including Japan. This study aimed to elucidate relative changes in the characteristics of inpatients in Japan related to this issue. METHODS: A total of 23 835 Japanese inpatients treated from 2010 to 2021 were enrolled (2010-2013, period I; 2014-2017, period II; 2018-2021, period III). Changes in clinical features were retrospectively analyzed based on ICD-10 diagnosis data. RESULTS: The percentage of patients aged over 75 years increased over time (period I, 38.0%; II, 39.5%, III, 41.4%). Emergency admissions comprised 27.5% of all in period I, which increased to 43.2% in period II and again to 44.5% in period III (P < 0.001). In period I, gastrointestinal disease, liver disease, pancreatic-biliary disease, and other disease types were noted in 47.4%, 29.5%, 19.2%, and 3.9%, respectively, while those values were 44.0%, 18.0%, 33.9%, and 4.1%, respectively, in period III (P < 0.001). The frequency of liver disease decreased by approximately 0.6-fold from periods I to III, while that of biliary-pancreatic disease increased by approximately 1.8-fold during that time. Both percentage and actual numbers of patients with biliary-pancreatic disease increased during the examined periods. Analysis of changes in the proportion of organs affected by malignancy during periods I, II, and III showed a marked increase in cases of biliary-pancreatic malignancy (11.6%, 19.5%, 26.6%, respectively) (P < 0.001). CONCLUSION: In association with the rapidly aging Japanese society, there has been an increasing frequency of biliary-pancreatic disease cases requiring hospitalization for treatment in the west Japan region of Shikoku.

Usefulness of aMAP Risk Score for Predicting Recurrence after Curative Treatment for Hepatocellular Carcinoma within Milan Criteria.

INTRODUCTION: The aMAP score is a prediction model for hepatocellular carcinoma (HCC) risk in chronic hepatitis patients. This study was conducted to elucidate the utility of this model for predicting initial recurrence of HCC in patients within the Milan criteria after undergoing curative treatment. METHODS: Patients with naïve HCC within the Milan criteria (n = 1,020) and treated from January 2000 to August 2022 were enrolled. The cohort was divided into two groups according to the aMAP score (high ≥60, low <60) and then compared for recurrence-free survival (RFS) and overall survival (OS). RESULTS: Comparisons between the high and low groups showed that etiology (HBV:HCV:HBV+HCV:NBNC = 41:79:2:37 vs. 65:589:11:196, p < 0.001), AST (36 vs. 46 IU/L, p < 0.001), and multiple HCC occurrence (15% vs. 22%, p = 0.026) were significantly different. Additionally, median RFS (59.8 vs. 30.9 months; p < 0.001) and median OS (154.1 vs. 83.4 months, p < 0.01) were greater in the low group. As for patients with HCC due to chronic viral hepatitis, there was a significant difference in median RFS between the groups (59.8 vs. 30.6 months, p < 0.001), especially for HCV-positive patients (53.1 vs. 27.2 months, p = 0.002). In patients with HCC due to a nonviral cause, the difference in median RFS between the low (70.9 months) and high (32.0 months) groups was not significant. DISCUSSION: Findings of this retrospective study indicate a significant association of elevated aMAP with worse RFS in patients with HCC caused by chronic viral hepatitis, especially those with HCV. The aMAP score is considered useful to predict not only HCC-carcinogenesis risk but also risk of recurrence following curative treatment.

Association of abnormal glucose tolerance with liver-related disease and cardiovascular diseases in patients with chronic hepatitis C.

AIM: Hepatitis C complicated by diabetes mellitus (DM) is considered a risk factor for the progression of fibrosis and development of hepatocellular carcinoma (HCC) and cardiovascular diseases. However, several studies may have lacked appropriate diagnosis of glucose intolerance. We aimed to examine the risk associated with abnormal glucose intolerance in the development of liver-related diseases, including HCC and complications of liver cirrhosis, such as ascites, esophageal and gastric varices, and hepatic encephalopathy, and cardiovascular diseases in patients with hepatitis C accurately diagnosed with impaired glucose tolerance. METHODS: This longitudinal retrospective study included 365 patients with chronic hepatitis C admitted to Ehime University Hospital for anti-hepatitis C therapy between September 1991 and January 2015. Patients were classified into normal glucose tolerance (NGT), prediabetes, and DM groups based on 75-g oral glucose tolerance test results. RESULTS: Both univariate and multivariate (adjusted for potential confounders) analyses revealed a significantly higher risk of developing HCC and cardiovascular events in the DM group than in the NGT group. However, in multivariate analysis, liver-related events, particularly liver cirrhosis complications, revealed no significant association. In addition, the prediabetes group had no significant risk of any outcome. CONCLUSIONS: Patients with hepatitis C complicated by DM, compared with patients with hepatitis C with NGT or complicated with prediabetes, have a higher risk of HCC and cardiovascular disease events, but not liver-related events, particularly in not developing liver cirrhosis complications. Therefore, appropriate follow-up is required for patients with hepatitis C based on their glucose tolerance status.

Role of B Cell-Activating Factor in Fibrosis Progression in a Murine Model of Non-Alcoholic Steatohepatitis.

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease all over the world. Therapeutic strategies targeting its multidirectional pathways are required. Particularly, fibrosis is closely associated with its prognosis. We previously found that B cell-activating factor (BAFF) is associated with severity of NAFLD. Here, we determined the direct in vivo role of BAFF in the development of liver fibrosis. Histological and biochemical analyses were performed using wild-type and BAFF-deficient mice. We established a murine model of non-alcoholic steatohepatitis (NASH) using carbon tetrachloride injection accompanied by high-fat/high-cholesterol diet feeding. Additionally, in vitro analysis using mouse macrophage-like cell line RAW264.7 and primary hepatic stellate cells was performed. Hepatic steatosis and inflammation, and most importantly, the progression of liver fibrosis, were ameliorated in BAFF-deficient mice compared to those wild-type mice in our model. Additionally, BAFF deficiency reduced the number of CD11c+ M1-type macrophages in the liver. Moreover, BAFF stimulated RAW264.7 cells to secrete nitric oxide and tumor necrosis factor α, which drove the activation of hepatic stellate cells. This indicates that BAFF plays a crucial role in NASH development and may be a promising therapeutic target for NASH.

Relationship between body composition and the histology of non-alcoholic fatty liver disease: a cross-sectional study.

BACKGROUND: Causes of non-alcoholic fatty liver disease and its progression include visceral fat accumulation and loss of muscle mass; however, which of the two phenomena is more critical is unclear. Therefore, we intended to examine the relationship between body composition and non-alcoholic fatty liver disease progression as indicated by fibrosis and the non-alcoholic fatty liver disease activity score. METHODS: This cross-sectional study comprised 149 patients (55 men; age, 20-76 years) treated for non-alcoholic fatty liver disease between December 2010 and January 2020. Body composition measurements, histological examinations of liver samples, and comprehensive blood chemistry tests were performed. The relationship between body composition and non-alcoholic fatty liver disease histology findings was analyzed using the logistic regression model. RESULTS: Fibrosis was significantly and inversely correlated with muscle mass and appendicular skeletal muscle mass and significantly and positively correlated with fat mass, fat mass/height squared, visceral fat area, and waist-hip ratio (P < 0.05). After adjustment for sex, blood chemistry measurements, and body composition indices, fibrosis remained associated with appendicular skeletal muscle mass, fat mass, fat mass/height squared, and visceral fat area (P < 0.05). Non-alcoholic fatty liver disease activity score ≥ 5 significantly correlated with fat mass and fat mass/height squared in a univariate but not multivariate analysis. CONCLUSIONS: Fibrosis in non-alcoholic fatty liver disease, an indicator of unfavorable long-term outcomes, is associated with more indices of fat mass than of those of muscle mass. Hence, fat mass should be controlled to prevent non-alcoholic fatty liver disease progression.

Tricks and traps of ICG endoscopy for effectively applying endoscopic transsphenoidal surgery to pituitary adenoma.

Differentiating tumor from normal pituitary gland is very important for achieving complete resection without complications in endoscopic endonasal transsphenoidal surgery (ETSS) for pituitary adenoma. To facilitate such surgery, we investigated the utility of indocyanine green (ICG) fluorescence endoscopy as a tool in ETSS. Twenty-four patients with pituitary adenoma were enrolled in the study and underwent ETSS using ICG endoscopy. After administering 12.5 mg of ICG twice an operation with an interval > 30 min, times from ICG administration to appearance of fluorescence on vital structures besides the tumor were measured. ICG endoscopy identified vital structures by the phasic appearance of fluorescent signals emitted at specific consecutive elapsed times. Elapsed times for internal carotid arteries did not differ according to tumor size. Conversely, as tumor size increased, elapsed times for normal pituitary gland were prolonged but those for the tumor were reduced. ICG endoscopy revealed a clear boundary between tumors and normal pituitary gland and enabled confirmation of no more tumor. ICG endoscopy could provide a useful tool for differentiating tumor from normal pituitary gland by evaluating elapsed times to fluorescence in each structure. This method enabled identification of the boundary between tumor and normal pituitary gland under conditions of a low-fluorescence background, resulting in complete tumor resection with ETSS. ICG endoscopy will contribute to improve the resection rate while preserving endocrinological functions in ETSS for pituitary adenoma.

Education and household income and carotid intima-media thickness in Japan: baseline data from the Aidai Cohort Study in Yawatahama, Uchiko, Seiyo, and Ainan.

BACKGROUND: Epidemiological evidence for the relationship between education and income and carotid intima-media thickness (CIMT) has been limited and inconsistent. The present cross-sectional study investigated this issue using baseline data from the Aidai Cohort Study. METHODS: Study subjects were 2012 Japanese men and women aged 34-88 years. Right and left CIMT were measured at the common carotid artery using an automated carotid ultrasonography device. Maximum CIMT was defined as the largest CIMT value in either the left or right common carotid artery. Carotid wall thickening was defined as a maximum CIMT value > 1.0 mm. RESULTS: The prevalence of carotid wall thickening was 13.0%. In participants under 60 years of age (n = 703) and in those aged 60 to 69 years (n = 837), neither education nor household income was associated with carotid wall thickening or with maximum CIMT. Among those aged 70 years or older (n = 472), however, higher educational level, but not household income, was independently related to a lower prevalence of carotid wall thickening: the multivariate-adjusted odds ratio for high vs. low educational level was 0.43 (95% confidence interval 0.21-0.83, p for trend = 0.01). A significant inverse association was observed between education, but not household income, and maximum CIMT (p for trend = 0.006). CONCLUSIONS: Higher educational level may be associated with a lower prevalence of carotid wall thickening and a decrease in maximum CIMT only in participants aged 70 years or older.

SARC-F combined with a simple tool for assessment of muscle abnormalities in outpatients with chronic liver disease.

AIM: An easily performed method for examination of muscle abnormalities is anticipated. We aimed to elucidate the clinical usefulness of simple assessments for muscle abnormality including a simple five-item questionnaire (SARC-F) in chronic liver disease patients. METHODS: From February to July 2019, 383 outpatients (median age 71 years, 259 men; chronic hepatitis (CH) : liver cirrhosis Child-Pugh A : liver cirrhosis Child-Pugh B : liver cirrhosis Child-Pugh C = 157:176:39:11) who underwent a computed tomography examination were enrolled. SARC-F, previously reported cut-off values for muscle strength decline (MSD; handgrip), pre-muscle volume loss (pre-MVL), calf circumference and finger-circle test results were used, and these results were analyzed retrospectively. RESULTS: A high SARC-F score (≥4) was observed in 25 patients, and a low score (<4) in 358 patients. The frequency of high SARC-F increased significantly with progression of chronic liver disease (chronic hepatitis : liver cirrhosis Child-Pugh A : liver cirrhosis Child-Pugh B/C = 2.5%:8.0%:14.0%, P=0.010). MSD frequency was 22.4% in men and 41.1% in women. Muscle volume loss and pre-MVL were noted in 22% and 30.5%, respectively, of the male patients, and 9.7% and 32.3%, respectively, of the female patients. In cases with high SARC-F and MSD, calf circumference and finger-circle abnormalities were found in 56% and 40.0% of patients, respectively, whereas those values for patients with low SARC-F and MSD were 14.5% and 10.6%, respectively (P < 0.001, for each; positive/negative predictive values: 0.560/0.855 and 0.400/0.894, respectively). Each SARC-F item showed a good area under the curve for MSD, but not pre-MVL. CONCLUSION: SARC-F score in combination with MSD and calf circumference or finger-circle test results may be an easy and simple method for surveillance of chronic liver disease patients with a high risk of sarcopenia and decline of quality of life.

Zinc deficiency as an independent prognostic factor for patients with early hepatocellular carcinoma due to hepatitis virus.

AIM: Although a reduced serum zinc level is often observed in patients with chronic liver disease due to hepatitis virus, its prognostic importance has not been adequately investigated. This study aimed to elucidate the association of zinc deficiency with prognosis, especially in early hepatocellular carcinoma (HCC) patients. METHODS: From 2005 to 2018, 466 patients with naïve HCC due to hepatitis virus were enrolled (327 men, 139 women; median age 70 years; hepatitis C virus [HCV] n = 389, hepatitis B virus [HBV] n = 69, hepatitis C virus and hepatitis B virus n = 8; Child-Pugh A n = 367, Child-Pugh B n = 82; Child-Pugh C n = 17; TNM-LCSGJ stage I n = 150, stage II n = 181, stage III n = 91, stage IVa n = 26, state IVb n = 18). Of the 466 patients, 287 were within the Milan criteria (early HCC) and treated curatively. Zinc deficiency was defined as <60 µg/dL. Clinical records and prognostic factors were retrospectively evaluated. RESULTS: The levels of serum zinc became lower with chronic liver disease progression (Child-Pugh A, B, C: 64.3 ± 14.3, 52.3 ± 15.7, 48.4 ± 13.5 µg/dL, respectively; P < 0.001). In early HCC patients treated curatively, overall survival and recurrence rates were better in patients treated curatively and without zinc deficiency as compared with patients with zinc deficiency (3-year overall survival 86.5% vs. 77.2%, 5-year overall survival 73.5% vs. 43.8%, P < 0.001; 3-year recurrence 44.8% vs. 58.3%, 5-year recurrence 56.8% vs. 77.5%, P = 0.002). Not only infection control of hepatitis virus (sustained virological response in HCV or nucleos(t)ide analogs in HBV; HR 0.078, P < 0.001), but also zinc deficiency (HR 1.773, P = 0.041) were significant prognostic factors for death. CONCLUSION: Serum levels of zinc were reduced in association with chronic liver disease grade progression. In addition to infection control of hepatitis virus, zinc deficiency might be a significant prognostic factor for survival in patients with early HCC due to viral hepatitis treated curatively.

Hearing Impairment and Prevalence of Mild Cognitive Impairment in Japan: Baseline Data From the Aidai Cohort Study in Yawatahama and Uchiko.

OBJECTIVES: Hearing impairment (HI) in midlife may increase the risk of dementia. However, epidemiological research on the association between HI and mild cognitive impairment (MCI) is very limited. DESIGN: The present cross-sectional study investigated the relationship between HI and MCI using baseline data from the Aidai Cohort Study. Study subjects were 995 Japanese adults aged 36 to 84 years. We used the audiometric definition of HI adopted by the World Health Organization, which identifies the speech-frequency pure-tone average hearing thresholds at 0.5, 1, 2, and 4 kHz tones. HI was defined as present when pure-tone average was >25 dB HL in the better hearing ear. MCI was defined as being present when a subject had a Japanese version of the Montreal Cognitive Assessment score of <26. Adjustment was made for age, sex, smoking status, alcohol consumption, leisure time physical activity, hypertension, dyslipidemia, diabetes mellitus, history of depression, body mass index, waist circumference, employment, education, and household income. RESULTS: Among the 995 study subjects, the prevalence values of HI and MCI were 24.3% and 44.5%, respectively. HI was independently positively associated with MCI: the multivariate-adjusted odds ratio (95% confidence interval) was 1.86 (1.32 to 2.62). HI was independently related to a higher prevalence of MCI in those aged 60 to 69 years and those aged 70 years or older: the multivariate-adjusted odds ratios (95% confidence intervals) were 1.64 (1.03 to 2.62) and 2.30 (1.04 to 5.27), respectively. CONCLUSIONS: HI may be associated with a higher prevalence of MCI.

Combination of Resection and Ablative Treatment for Hepatocellular Carcinoma: Usefulness of Complementary Radiofrequency Ablation.

AIM/BACKGROUND: In HCC patients with multiple tumors in separate segments, monotherapy with surgical resection is often difficult when the estimated residual liver volume after surgery is thought to be inadequate. We evaluated the usefulness of resection combined with low invasive radiofrequency ablation (RFA) for treatment of such cases. MATERIALS/METHODS: We analyzed 115 HCC patients with countable multiple tumors (≤5) without vascular invasion and/or extrahepatic metastasis, and treated solely with resection (SR group: n = 82), or with both resection and RFA (Comb group: n = 33) from January 2000 to December 2017. Clinical characteristics, overall survival rate (OSR), and disease-free survival rate (DFSR) were analyzed in a retrospective manner. RESULTS: There were 88 males (76.5%) and the average age of all patients was 67.8 ± 8.9 years. The average number of tumors and average maximum tumor size were 2.4 ± 0.7 and 4.1 ± 2.1 cm, respectively. Forty-two (36.5%) patients were classified as beyond up-to-7 criteria. The 3- and 5-year OSRs in the SR group were 82.0 and 67.0%, respectively, and in the Comb group were 75.2 and 65.6%, respectively (p = 0.244), while the 3- and 5-year DFSRs in the SR group were 45.2 and 28.0%, respectively, and those in the Comb group were 37.3 and 23.3%, respectively (p = 0.257). CONCLUSION: The combination of surgical resection and complementary RFA may be an effective strategy for treating HCC patients with countable multiple tumors, who are otherwise difficult to treat with surgical resection or RFA alone.

Prediction of risk of falls based on handgrip strength in chronic liver disease patients living independently.

AIM: Falling is known to be associated with cognitive function. We evaluated the relationship between muscle function and falls in patients with chronic liver disease (CLD). METHODS: We enrolled 100 sequential CLD patients without dementia who were admitted to our institution for scheduled treatment from July 2017 to May 2018 (age 71.0 ± 10.2 years; 76 men). All subjects were self-reliant in regard to activities of daily living. On admission, handgrip strength was determined and falls within 1 month of admission were noted. For determining handgrip strength decline (HSD), previously reported values were used (men, <26 kg; women, <18 kg). The relationship between HSD and falls in CLD patients was evaluated in a retrospective manner. RESULTS: Thirty-two patients had chronic hepatitis and 49 had liver cirrhosis (LC) Child-Pugh A, 17 had LC Child-Pugh B, and 2 had LC Child-Pugh C. Twelve (12.0%) had a history of falling, including 8 (26.7%) of 30 with and 4 (5.7%) of 70 without HSD (P = 0.006). The cut-off value for age in relationship to falling was 69.0 years old (area under the receiver operating characteristic curve, 0.668; 95% confidence interval, 0.514-0.821). A fall during hospitalization was noted more often in patients with a history of falling than in those without (16.7% [2/12] vs. 2.3% [2/88], P = 0.018). CONCLUSION: In CLD patients, the presence of HSD and older age might be independent risk factors for predicting a fall. Assessment of handgrip strength could be an effective clinical tool for easily assessing the risk of falling, especially in elderly CLD patients.

Clinical effectiveness of switching between DPP-4 inhibitors in patients with type 2 diabetes mellitus
.

OBJECTIVES: Dipeptidyl peptidase-4 inhibitors (DPP-4Is) can be classified into three categories according to their binding subsites. We wished to clarify the efficacy of switching between DPP-4Is according to their binding subsites. MATERIALS AND METHODS: We undertook a retrospective study of the medical records of patients who switched from one DPP-4I to another. RESULTS: Among 62 patients eligible for study inclusion, the mean change in the glycated hemoglobin (HbA1c) level between different categories of DPP-4I was -0.35 (95% CI, -0.12 to -0.58; n = 59). The mean change in the HbA1c level between each class of DPP-4I was calculated. From class 3 to class 2 it was -0.45 (n = 25); from class 3 to class 1 it was -0.36 (n = 17); from class 1 to class 2 it was -0.24 (n = 7); from class 1 to class 3 it was 0.33 (n = 4); from class 2 to class 1 it was -0.30 (n = 5); from class 2 to class 3 it was -1.30 (n = 1). CONCLUSIONS: When switching DPP-4Is because of insufficient efficacy, consideration of their DPP-4 binding site may be beneficial.

Lenvatinib-induced thyroid abnormalities in unresectable hepatocellular carcinoma.

Lenvatinib has anti-tumor activity against advanced hepatocellular carcinoma (HCC). Hypothyroidism is also a frequent complication in patients treated with lenvatinib. However, studies on lenvatinib-induced thyroid toxicity and destructive thyroiditis are limited. Therefore, this study aimed to clarify the frequency and timing of thyroid abnormalities in lenvatinib for unresectable HCC. This retrospective study enrolled 50 patients with advanced HCC treated with lenvatinib. Patients were classified to have euthyroid, subclinical hypothyroidism, overt hypothyroidism, and thyrotoxicosis. The timing of thyroid dysfunction was assessed, and risk factors for incident hypothyroidism or thyrotoxicosis were evaluated using multivariate models. Subclinical hypothyroidism, overt hypothyroidism, and thyrotoxicosis occurred in 7 (14.0%), 26 (52.0%), and 5 (10.0%) patients, respectively. In the 33 patients with hypothyroidism, 27 (84.4%) developed the condition within 2 weeks of starting lenvatinib treatment. Of the 5 patients with thyrotoxicosis, 3 developed the condition within 8 weeks of starting lenvatinib administration. One patient developed thyrotoxicosis in only 1 week of the initiation of treatment. No correlation between the presence of antibodies and the incidence and severity of thyroid dysfunction due to the autoimmune mechanism was observed. The progression-free survival was significantly better in the hypothyroidism group. Lenvatinib treatment for unresectable HCC not only causes hypothyroidism, but also thyrotoxicosis. Moreover, these thyroid conditions develop within the early period of treatment at a higher prevalence. Patients with thyroid dysfunction had better prognosis. Based on these results, in patients administered with lenvatinib, there is need for careful assessment for the possibility of thyroid dysfunction from the onset of treatment.

Effects of Motilin Receptor Agonists and Ghrelin in Human motilin receptor Transgenic Mice.

Gastrointestinal motility is regulated by neural factors and humoral factors. Both motilin and ghrelin improve gastrointestinal motility, but many issues remain unclear. We prepared human motilin receptor transgenic (Tg) mice and performed experiments evaluating the effects of motilin, erythromycin (EM), and ghrelin. EM and ghrelin promoted gastric emptying (GE) when administered either peripherally or centrally to Tg mice. Atropine (a muscarinic receptor antagonist) counteracted GE induced by centrally administered EM, but not that induced by peripherally administered EM. The administration of EM in this model promoted the effect of mosapride (a selective serotonin 5-hydroxytryptamine 4 (5-HT4) receptor agonist), and improved loperamide (a µ-opioid receptor agonist)-induced gastroparesis. The level of acyl-ghrelin was significantly attenuated by EM administration. Thus, we have established an animal model appropriate for the evaluation of motilin receptor agonists. These data and the model are expected to facilitate the identification of novel compounds with clinical potential for relieving symptoms of dyspepsia and gastroparesis.

Muscle volume loss a prognostic factor for death in liver cirrhosis patients and special relationship to portal hypertension.

AIM: We examined the prognosis of liver cirrhosis (LC) patients with and without portal hypertension (PHT) and muscle volume loss (MVL). METHODS: From 2006 to 2016, 346 LC outpatients (PHT/non-PHT = 173/173) were enrolled (median age, 69 years; men / women, 204/142; Child-Pugh A / B, 230/116; and presence of MVL 15.6% in each group) after propensity matching, following exclusion of those with hepatocellular carcinoma (HCC) beyond the Milan criteria and Child-Pugh C. Portal hypertension was defined as positive for significant esophagogastric varices; MVL was diagnosed based on a previously reported index using CT imaging. Overall survival rate (OSR) was evaluated from the viewpoints of PHT and MVL. RESULTS: There were no significant differences in clinical background (age, gender, etiology, presence of HCC [within Milan criteria], or Child-Pugh class) between the groups. Although there was no significant difference regarding OSR between patients with and without MVL in the non-PHT group (P = 0.076, Holm's method), the OSR of patients with MVL in the PHT group was lower compared to those without MVL in both groups (P = 0.017 and P = 0.012, respectively, Holm's method). As a result, the OSR of patients with MVL (n = 54) was lower than the other patients (n = 292) (3- and 5-year OSR, 69.0% vs. 86.4% and 35.8% vs. 74.1%, respectively; P < 0.001). Multivariate Cox hazard analysis showed that positive for HCC (hazard ratio [HR], 2.028; 95% confidence interval [CI], 1.189-3.460; P = 0.009) and positive for MVL (HR, 2.768; 95% CI, 1.575-4.863; P < 0.001) were significant independent prognostic factors for death. CONCLUSION: Muscle volume loss and HCC, but not PHT, were found to be independent prognostic factors for death in LC patients.

Relative changes in handgrip strength and skeletal muscle volume in patients with chronic liver disease over a 2-year observation period.

AIM: There are few reports regarding relative changes in muscle function of patients with chronic liver disease (CLD). We examined CLD patients to evaluate relative changes in handgrip strength and muscle volume. METHODS: We enrolled 413 CLD outpatients who underwent handgrip strength measurements in both 2015 and 2017 (age 67.9 ± 10.0 years; male / female = 242/171; hepatitis C virus [HCV] / hepatitis B virus [HBV] / HBV and HCV / alcohol / others = 239/92/4/22/56; Child-Pugh score [CPS] in 2015 [5/6/7/8/9/≥10 = 335/51/12/11/3/1]). Relative change in muscle volume (ΔPI) from 2015 to 2017 was evaluated using computed tomography findings in 230 of the patients, using a previously reported method. Clinical characteristics, as well as relative changes of handgrip strength (ΔHGS) and ΔPI were analyzed. RESULTS: For the patient cohort as a whole, CPS became significantly worse in 2017 (5/6/7/8/9/≥10 = 319/56/13/11/5/9; P = 0.002). In individual patients with CPS decline, serum albumin level was significantly decreased (3.78 ± 0.50 to 3.33 ± 0.61 g/dL; P < 0.001), whereas no decrease was seen in those without such a decline (4.16 ± 0.48 to 4.20 ± 0.44 g/dL; P = 0.028). Furthermore, ΔHGS (-1.4 ± 4.8 [n = 59] vs. 0.7 ± 4.8 kg [n = 354]; P = 0.002) and ΔPI (-0.44 ± 0.88 [n = 38] vs. 0.03 ± 0.64 cm2 /m2 [n = 192]; P = 0.003) were worse in patients with, compared to those without, a decline in CPS. Age was not significantly different between patients with and without handgrip strength decline (66.5 ± 10.3 vs. 65.3 ± 9.9 years; P = 0.256). There was a significant relationship between ΔHGS, ΔPI and relative change in serum albumin (r = 0.161, P = 0.001 and r = 0.225, P < 0.001, respectively). CONCLUSION: Decline in CPS, especially decreasing serum albumin level, showed a significant relationship with muscle function reduction and muscle volume loss.
