ABSTRACT
Spontaneous coronary artery dissection (SCAD) is diagnosed in a very small percentage of patients with suspected acute coronary syndromes who undergo emergency coronary angiography. Although fibromuscular dysplasia (FMD) is known to coexist in patients with SCAD, the vascular sites of FMD and their frequency have not yet been clarified. We retrospectively reviewed the medical records of 16 patients who were diagnosed with and treated for SCAD at our hospital between 1 January 2011 and 31 January 2023. We have summarized their baseline and clinical characteristics and medical variables, including coronary and upper extremity angiography and in-hospital outcomes. One of our patients had concurrent cardiac tamponade requiring pericardial drainage, and another went into hemorrhage shock the following day from dissection of the gastric retroperitoneal artery. Characteristic angiographic features of partial or diffuse nonatherosclerotic stenosis were observed mainly in the distal parts of the coronary arteries or their branches. Notably, in six patients with SCAD who underwent upper extremity angiography, FMD of the brachial artery was revealed. For the first time, to our knowledge, we found a high prevalence of multifocal FMD of the brachial artery in patients with SCAD.

INTRODUCTION AND OBJECTIVES: Genetic background may be involved in the mechanisms of liver injury and the development of non-alcoholic fatty liver disease (NAFLD). However, its contributions to the long-term outcome of NAFLD have been unclear. METHODS: We enrolled 314 Japanese patients with biopsy-confirmed NAFLD from 2000 to 2018 (161 men [51.3%]; median age, 53 [14-84] years; 114 with advanced fibrosis [37.5%]) in the patients without hepatocellular carcinoma at diagnosis. Genomic DNA was extracted from peripheral blood and single nucleotide polymorphisms (SNPs) were analyzed. Associations of mortality with patatin-like phospholipase 3 (PNPLA3) and aldehyde dehydrogenase 2 (ALDH2) were analyzed. Finally, a subgroup analysis according to lifestyle-related disease was performed. RESULTS: During the median 7 years of follow-up, 20 patients (6.4%) died (13 liver-related [4.1%] and 7 non-liver-related deaths [2.2%]). Patients with ALDH2 (non-GG genotype) who had reduced alcohol metabolism tended to have a poor prognosis (pâ¯=â¯0.06). Patients carrying both risk SNPs of PNPLA3 (GG) and ALDH2 (non-GG) had a significantly poor prognosis (pâ¯=â¯0.01). In the subgroup analysis, patients with PNPLA3 (GG) who were non-diabetics (pâ¯=â¯0.06) or non-dyslipidemic (pâ¯=â¯0.03), with ALDH2 (non-GG) who were non-dyslipidemic (pâ¯=â¯0.01) or hypertensive (pâ¯=â¯0.03), also had a poor prognosis. The Cox analysis revealed that ALDH2 (non-GG) was associated with a poor prognosis (Hazard ratio: 4.568, 95% Confidence Interval: 1.294-16.131, pâ¯=â¯0.02) similar to the liver function tests. CONCLUSIONS: Genetic background may affect NAFLD prognosis and ALDH2 SNP could predict the outcome.

BACKGROUND AND AIM: The incidence of mortality and hepatocellular carcinoma (HCC) in patients with non-alcoholic fatty liver disease (NAFLD) has been reported, but the long-term outcomes of Japanese patients with NAFLD are not fully evaluated. METHODS: We enrolled 365 Japanese patients with biopsy-confirmed NAFLD (1990-2008) followed for ≥ 6 months: 185 males (50.7%); median age (54 years); advanced fibrosis 108 (29.8%); HCC, n = 26 (7.1%); diabetes, n = 191 (52.3%); dyslipidemia, n = 234 (64.1%); and hypertension, n = 193 (52.9%). We analyzed the survival and new-onset HCC rates for hepatic fibrosis as well as complications and the treatment of lifestyle-related diseases. RESULTS: During the median 7.1-year follow-up, 44 patients (12.1%) died: n = 28 liver-related (10 years liver-related death, 9.4%) and n = 16 non-liver-related deaths (10 years non-liver-related death, 4.9%). Both incidence rates were significantly higher in the advanced fibrosis group. The incidence of HCC at 10 years was 20.1% in the advanced fibrosis group, and the mortality was increased in patients with higher age, history of HCC, lower seru\m level of albumin, higher level of γ-glutamyltransferase, and insulin treatment for diabetes. Risk factors for HCC onset were higher levels of aspartate aminotransferase and triglyceride and hypertension treatment. Platelet count < 11.5 × 104 /µL was revealed as a risk factor for death and HCC development. CONCLUSIONS: The rates of both liver-related and non-liver-related deaths and HCC development were significantly prominent in the patients with advanced fibrosis. It is important to identify and treat NAFLD patients who have several risk factors and advanced fibrosis, which might be predicable simply by the platelet count.

BACKGROUND AND AIM: We evaluated the characteristics of hepatocellular carcinoma (HCC) in patients who had non-alcoholic fatty liver disease (NAFLD) without cirrhosis. METHODS: We prospectively followed NAFLD patients at our University hospital. NAFLD was diagnosed from detection of steatosis by histology or imaging, no alcohol intake, and exclusion of other liver diseases. Cirrhosis was defined by histological features, imaging data, and symptoms. We compared NAFLD-related HCC with or without cirrhosis and non-cirrhotic NAFLD with or without HCC. RESULTS: There were 48 non-cirrhotic HCC patients and 71 cirrhotic HCC patients. Multiple logistic regression analysis revealed that other than liver function factors, male gender (OR: 5.603, 95%CI: 1.577-19.900), light drinker (OR: 2.797, 95%CI: 1.031-7.589), and tumor size (OR: 1.031, 95%CI 1.009-1.055) differ significantly between these two groups. The recurrence rate was significantly lower in the non-cirrhotic HCC group than the cirrhotic HCC group, with risk factors being des-γ-carboxy prothrombin and the number of HCCs. The non-cirrhotic HCC group showed significantly better survival because of absence of non-cancerous liver failure. Comparison between non-cirrhotic NAFLD patients with or without HCC (n = 612) revealed the following risk factors for HCC: male gender (OR: 7.774, 95%CI: 2.176-27.775), light drinker (OR: 4.893, 95%CI: 1.923-12.449), and high FIB4 index (OR 2.634, 95%CI: 1.787-3.884). CONCLUSION: In patients with non-cirrhotic NAFLD, important risk factors for HCC were male gender, alcohol consumption, and the FIB4 index. HCC recurrence and survival were only influenced by the tumor stage. We should be aware of alcohol consumption as a modifiable risk factor for HCC.

BACKGROUND AND AIM: The incidence of acute hepatitis A [AH (A)] is decreasing because of improvements in hygiene; however, cases of sporadic severe hepatitis are still being reported. We assessed the epidemiology of AH (A) in Japan. METHODS: This was a hospital-based retrospective study, in which 126 AH (A) patients (96 men [76%], median age 39 [range, 19-66] years) were enrolled. Patients diagnosed with AH (A) before 2001 (n = 79) and after 2001 (n = 47) were compared. RESULTS: The incidence of AH (A) showed peaks in 1990, 1999, and 2018. After 2001, one patient had hepatitis B virus, four had human immunodeficiency virus, and three had syphilis coinfections. Before and after 2001, HAV was transmitted, respectively, by raw oysters (28% and 26%), overseas travel (19% and 28%), and sexual contact (0% and 19%) (P < 0.01). The frequencies of symptoms were appetite loss (51% and 32%), fever (63% and 81%), and diarrhea (3% and 13%) (all P < 0.05), respectively. On admission, the median levels of alanine aminotransferase (1455 and 3069 U/L) and γ-glutamyl transpeptidase (221 and 345 U/L) were significantly higher (P < 0.01), and the prothrombin time (77.5% and 65.9%) and platelet count (22.7 and 16.4 × 10/µL) were significantly lower after 2001 (P < 0.05). A time to normalization of the bilirubin level ≥ 30 days was associated with older age and a diagnosis of AH (A) after 2001. CONCLUSIONS: Outbreaks and severe AH (A) cases due to sexual transmission have been reported recently. It is necessary to examine their sexual behavior and other sexual infection.

BACKGROUND AND AIM: To elucidate features of nonobese non-alcoholic fatty liver disease (NAFLD), we assessed Japanese patients with NAFLD stratified by body mass index (BMI) and by sex. METHODS: Biopsy-proven 762 NAFLD patients (404 men) were classified into three groups by the Japanese criteria: nonobese group (BMI < 25 kg/m2 ), obese group (25 to 30), and severely obese group (≥ 30). Clinicopathological features and single nucleotide polymorphism of patatin-like phospholipase 3 (PNPLA3) rs738409 were investigated, and body composition analysis was performed by bioelectrical impedance analysis and computed tomography. RESULTS: Over 25% of men and almost 40% of women were nonobese, but most of them had visceral fat obesity and/or insulin resistance. The median age (years) of the nonobese, obese, and severely obese men was 49.9, 46.8, and 40.5 (P < 0.01), respectively, while those of women was 60.2, 59.6, and 48.5 (P < 0.01), respectively. The prevalence of metabolic comorbidities and PNPLA3 risk alleles did not differ among these groups in both sexes. Also, the prevalence of non-alcoholic steatohepatitis was not significantly different in both sexes, although nonobese patients had a higher prevalence of mild steatosis. Advanced fibrosis showed a marked difference between men and women. Advanced fibrosis was significantly more frequent among severely obese men (nonobese: 31.0%, obese: 41.6%, severely obese: 60.9%; P < 0.01), but it was lower among severely obese women (51.4%, 62.9%, 33.7%; P < 0.01). Skeletal muscle mass was significantly lower in nonobese patients. CONCLUSIONS: Non-alcoholic fatty liver disease was not milder in nonobese patients. Histological steatosis was associated with BMI, but advanced fibrosis was not and showed a significant sex difference.

BACKGROUND AND AIM: The prevalence of hepatocellular carcinoma (HCC) associated with nonalcoholic fatty liver disease (NAFLD-HCC) is increasing. Unfortunately, NAFLD frequently develops into HCC without liver cirrhosis. Therefore, we investigated the clinical features of HCC in NAFLD patients without advanced fibrosis. METHODS: We compared clinical characteristics, survival rates, and recurrence rates between 104 NAFLD-HCC patients diagnosed between January 2000 and December 2016, including 35 without (F0-2) and 69 with advanced fibrosis (F3-F4). Risk factors associated with survival and recurrence were evaluated. RESULTS: In total, 66.3% of those diagnosed had advanced fibrosis, 58.8% in men and 80.5% in women (men vs women, P = 0.03). In NAFLD-HCC without advanced fibrosis, tumor size was significantly larger and liver histological activity was lower than those in patients with advanced fibrosis. Survival rates between the two groups did not differ. Among those achieving curative treatment, the recurrence rate was significantly lower in NAFLD-HCC without advanced fibrosis (P < 0.01). Risk factors of recurrence were male gender, lower serum albumin, and advanced fibrosis. CONCLUSIONS: In men, HCC tended to develop from NAFLD without advanced fibrosis. Although tumor size in NAFLD-HCC without advanced fibrosis is significantly larger, the recurrence rate is significantly lower. Surgical therapy should be strongly considered in these cases.

AIMS: Steatohepatitic hepatocellular carcinoma (SH-HCC) is a newly proposed concept, which shows histological features of steatohepatitis in HCC lesions, and it is strongly associated with metabolic syndrome (MS) and steatosis/steatohepatitis in non-cancerous lesions. Recently, a substantial number of HCC associated with MS were reported to have developed from pre-existing inflammatory hepatocellular adenoma (HCA). To elucidate the characteristic features of SH-HCC, we clinicopathologically investigated strictly diagnosed SH-HCC and non-SH-HCC (standard HCC). METHODS: This was a retrospective multicenter study. A clinicopathological investigation was undertaken to compare 62 cases with SH-HCC features to 31 age- and sex-matched standard HCC cases, including an immunohistochemical study using markers for classification of HCA and diagnosis of HCC. RESULTS: The characteristic features of SH-HCC compared with standard HCC include a higher rate of complications of MS, more frequent non-alcoholic fatty liver disease as an underlying liver disease, and HCC development in non-cirrhotic liver. The rate of solitary tumors showed no difference between the two groups, but the median diameter of the main tumor was greater in SH-HCCs (45 mm/20 mm, P = 0.01). The HCCs were mostly moderately differentiated, and the patterns were mainly trabecular in both groups. Positive findings for serum amyloid A and C-reactive proteins, classification markers of inflammatory HCA, were significantly higher in cancerous lesions of SH-HCC cases (50%/13%, P < 0.01 and 42%/16%, respectively; P = 0.01). CONCLUSIONS: We confirmed that SH-HCC was strongly associated with MS and NAFLD, and found that classification markers of inflammatory HCA were significantly higher in SH-HCC. Further studies are needed to elucidate the relationship between SH-CCC and HCA for understanding the carcinogenic pathways in these diseases.

BACKGROUND: Diminishing yellow color is associated with plaque stabilization. We assessed the hypothesis that a combination of ezetimibe and statin provides more effective plaque stabilization and regression than statin alone as assessed by plaque color.MethodsâandâResults:Stable coronary artery disease patients (n=131) who underwent elective percutaneous coronary intervention and had yellow plaques were randomized to combination therapy (atorvastatin 10-20 mg and ezetimibe 10 mg/day; Group C) or statin monotherapy (atorvastatin 10-20 mg; Group M). Changes in plaque color and plaque volume during 9 months were assessed by angioscopy and intravascular ultrasound. Low-density lipoprotein cholesterol (LDL-C) decreased from 103±28 to 63±18 mg/dL in Group C (P<0.001) and from 100±28 to 75±17 mg/dL in Group M (P<0.001). Yellow color grade decreased significantly in both Group M (2.1±1.1 vs. 1.7±1.0, P=0.005) and Group C (2.2±1.2 vs. 1.8±1.2, P=0.002), but did not differ between the groups. %plaque volume did not change in Group M (48.5±10.2% vs. 48.2±10.4%, P=0.4), but decreased significantly in Group C (50.0±9.8% vs. 49.3±9.8%, P=0.03). CONCLUSIONS: Compared with statin monotherapy, combination therapy with ezetimibe further reduced LDL-C levels. Significant plaque volume reduction was achieved by the combination therapy, but not statin monotherapy; however, plaque stabilization was similarly achieved by both therapies. Furthermore, reduction in plaque volume was dependent on reduction in LDL-C, regardless of whether it was achieved by statin alone or statin plus ezetimibe.

AIM: The vasopressin V2 receptor antagonist tolvaptan has been used for the treatment of cirrhotic patients with ascites; however, no predictor of efficacy and prognosis has been developed. We evaluated candidate predictors of response to tolvaptan treatment. METHODS: This was a single-center retrospective study. Overall, 97 Japanese cirrhotic patients (60 men, median age 63 years), who were hospitalized for ascites treatment including oral tolvaptan coupled with conventional diuretics, were enrolled. The efficacy of tolvaptan was defined as a urination increase of ≥500 mL or a urine volume ≥2000 mL/day on the day following treatment. The prognosis of tolvaptan treatment was evaluated by the post-treatment survival time by Kaplan-Meier analysis. RESULTS: Tolvaptan therapy was effective in 67% of cirrhotic patients. Patients showed -1.5 (-17.2 to +6.2) kg change in body weight and 40% achieved ≥2.0 kg reduction in body weight after 1 week of treatment. Platelet counts, urine sodium (Na) level, and urine Na/potassium (Na/K) ratio were higher, and the blood urea nitrogen (BUN)/creatinine (Cr) ratio was lower, in cases showing a response to tolvaptan. The combination of a BUN/Cr ratio ≥17.5 and urine Na/K ratio <3.09 was predictive of being non-responsive to tolvaptan, and the response rate in these patients was only 39% (P < 0.01). The mean post-treatment survival duration was significantly longer in patients who responded to tolvaptan therapy. CONCLUSIONS: Urinary BUN and Na excretion were predictive of a response to tolvaptan, and tolvaptan treatment may improve the prognosis of cirrhotic patients.
ABSTRACT
Poorly controlled diabetes mellitus (DM) patients sometimes show serum transaminase elevations due to steatohepatitis. However, we experienced four cases with type 1 DM with sharp elevations in serum transaminases that could not be explained by steatohepatitis alone and showed bright liver. They were diagnosed with glycogenic hepatopathy (GH) clinicopathologically. The four patients had a median age of 22.5 years (range, 19-29 years) and 12.5 (4-15)-year histories of type 1 DM and showed marked increases in serum transaminases (aspartate aminotransferase, 698 U/L [469-2763 U/L]; alanine transaminase, 255 U/L [216-956 U/L]). Diabetes mellitus control was poor and hemoglobin A1c was 12.7% (11-16.5%). Three cases had a past history of diabetic ketoacidosis. Hepatomegaly and hyperdense liver were seen on computed tomography scans. Magnetic resonance imaging showed low intensity in T2-weighted images. The pathological findings revealed pale and swollen hepatocytes and glycogenated nuclei. The architecture of the liver was preserved, and steatosis and fibrosis were mild. The cytoplasm of hepatocytes stained densely positive with periodic acid-Schiff, and the positive staining disappeared after diastase digestion, suggesting glycogen deposition. No other cause of hepatitis was evident, and the diagnosis was GH. Elevated transaminases improved within 1 month with good glycemic control. Transaminase elevations were observed several times in three cases with poor glycemic control. Glycogenic hepatopathy is rare, but extremely high serum elevations of transaminases are important to identify clinically. Despite showing a good clinical course in general, GH sometimes recurs and requires strict glycemic control. Clinicians should be aware of and recognize GH when dealing with uncontrolled DM patients.
ABSTRACT
Therapeutic devices for acute myocardial infarction (AMI) have evolved dramatically in recent years. However, the impact of the Killip classification of AMI outcomes in patients undergoing aggressive percutaneous coronary intervention remains unclear. We performed a 10-year retrospective review of 2062 patients diagnosed with AMI, and divided the data into two 5-year intervals: 2005-2009 (n = 1071), and 2010-2014 (n = 991). No difference was observed in in-hospital mortality rate between the two periods (first period, 11.5% vs second period, 9.7%; P = 0.19). The incidence of stent thrombosis was not significantly different between the two periods, and very few thrombi occurred in patients who received second-generation drug-eluting stents (DES) (0.98%: 5/511). In-hospital mortality due to stent thrombosis was high in the full cohort (15%). During the second period, in-hospital mortality was lower in Killip class 4 patients, although the difference was not significant (59.1 vs 47.5%, P = 0.07). Multivariable logistic regression identified several factors that significantly affected in-hospital mortality, including age [odds ratio (OR) 1.07], left main trunk (OR 2.47), peak CPK value above 5000 IU/L (OR 3.18), and Killip class 4 (OR 15.63). We evaluated trends in in-hospital mortality among patients with AMI over a 10-year period. New DES and the frequent use of mechanical support in patients with hemodynamic compromise tended to improve in-hospital mortality, but the effect was not significant. Notably, Killip class 4 on admission was associated with an estimated 16-fold increased risk of in-hospital death.

AIM: Recently, the short-term efficacy of the vasopressin V2 receptor antagonist tolvaptan for the treatment of ascites in cirrhosis was reported. However, the long-term effects remain unknown. Here, we report the clinical features of decompensated cirrhosis treated using long-term tolvaptan therapy, and evaluate its safety and efficacy. METHODS: Fifty-five cirrhotic patients hospitalized due to ascites, despite receiving appropriate diuretic treatment, were treated with tolvaptan. We excluded 35 patients due to liver transplant (20.0%), death (28.6%), poor general status (14.3%), improved ascites (5.7%) or other reasons (31.4%). In 20 cases treated with tolvaptan for 6 months, total body water (TBW) and extracellular fluids (ECW) were measured using bioelectric impedance analysis (BIA) with an InBody720. RESULTS: The median age of the 20 patients was 64 years (range, 48-90), and 60% were male. The etiology of cirrhosis included hepatitis C (45%), alcohol-induced (20%) and other (35%). The percentage of patients with Child-Pugh class A, B and C was 0%, 40% and 60%, respectively. Biochemical findings revealed that serum creatinine levels and estimated glomerular filtration rate were not affected during 6 months of treatment with tolvaptan, and there was no renal disturbance. The median serum sodium levels were increased from 138 to 139 mEq/L, but serious adverse events related to renal and liver function were not observed. Data also revealed that long-term treatment reduced the BIA-estimated ECW/TBW ratio. CONCLUSION: Long-term tolvaptan treatment was a safe and effective treatment for decompensated cirrhosis.
ABSTRACT
Experimental ischemia-reperfusion models have shown that 3-hydroxy-3methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, statins, have cardioprotective effects. SAMIT (Statin Acute Myocardial Infarction Trial) is a multicenter prospective open randomized trial, designed to evaluate the effects of statin treatment from the earliest stage on cardioprotection in patients with acute myocardial infarction (AMI). Patients were randomly assigned to receive atorvastatin (initial dose of 40 mg at admission followed by the maintenance dose of 10 mg/day for 30 days) or not (control), and then immediately underwent percutaneous coronary intervention (PCI) for the culprit lesion. The primary endpoints were infarct size and left ventricular function. The secondary endpoints were major adverse cardiac and cerebrovascular events (MACCE) and various biomarkers. There were no significant differences in baseline characteristics between 2 groups of the statin treatment group and the control group. The left ventricular ejection fraction increased at 6 months after the onset of AMI, compared with the baseline level in the atorvastatin group (P < 0.05), while it did not change in the control group. Although there were no significant differences in the MACCE, the changes in the levels of angiopoietin-like protein 2 (ANGPTL2) (P < 0.05), and glyceraldehyde-derived advanced glycation end-products, (TAGE) (P < 0.01) were suppressed at 2 weeks in the atorvastatin group, compared with the control group. Statin therapy started early after the onset reduced the levels of ANGPTL2 and TAGE, and thus, might have cardioprotective effects in patients with AMI.

The mortality rate due to rupture of aortic dissection and aortic aneurysm is approximately 90%. Acute aortic rupture can be fatal prior to hospitalization and has proven difficult to diagnose correctly or predict. The in-hospital mortality rate of ruptured aortic aneurysm ranges from 53 to 66%. Emergency surgical and endovascular treatments are the only options for ruptured aortic dissection and aortic aneurysm. No method of systematic early detection or inspection of vessel injury is available at the prevention stage. Regardless of the improvement in many imaging modalities, aortic diameter has remained a major criterion for recommending surgery in diagnosed patients. Previous reports have suggested a relationship between vulnerable plaque and atherosclerotic aortic aneurysm. Non-obstructive angioscopy is a new method for evaluating intimal injury over the whole aorta. It has been used to identify many advanced atherosclerotic plaques that were missed on traditional imaging modalities before aneurysm formation. Non-obstructive angioscopy has shown that atherosclerosis of the aorta begins before that of the coronary artery, which had been noted on autopsy "in vivo". Strong or repetitive aortic injuries might cause sudden aortic disruption. Aortic atheroma is also a risk factor of stroke and perivascular embolism. Detecting aortic vulnerable atherosclerotic plaque on non-obstructive angioscopy may not only clarify the pathogenesis of acute aortic rupture and "aortogenic" thromboemboli and atheroemboli but also play a role in the pre-emptive medicine.

This study aimed to clarify the relationships between arterial remodeling patterns and plaque volume regression or stabilization. The TOGETHAR trial is a prospective open-label trial designed to assess coronary plaque regression and stabilization with multiple plaque imaging modalities following 52 weeks of pitavastatin treatment (2 mg/day). Coronary plaques were observed in 46 patients with both angioscopy and intravascular ultrasound at baseline and after 52 weeks of drug treatment. We divided these patients into three groups according to their remodeling indices (RI). Group P consisted of patients with a baseline RI >1.05, Group M of patients with a baseline RI of 0.95-1.05, and Group N of patients with a baseline RI <0.95 and then evaluated differences in coronary plaque volume changes and yellow grade among the three groups. In the positive remodeling group, whose remodeling index (RI) exceeded 1.05 at baseline, RI and percent atheroma volume (PAV) were significantly reduced (RI 1.14 ± 0.07 to 1.05 ± 0.10, p = 0.010, PAV 47.3 ± 8.3 to 45.3 ± 7.3 mm(3), p = 0.048). There was no relationship between baseline RI and the change in yellow grade of plaque. RI increased without significant change of PAV or a decrease in lumen volume in group N, with RI below 0.95 at baseline. Plaques with positive remodeling were more likely to have plaque volume regression by pitavastatin than those without in patients with coronary artery disease. Moreover, plaques with positive and negative remodeling were changed into those with intermediate remodeling by pitavastatin. Pitavastatin might induce not only plaque regression or stabilization, but also conformational normalization of vessel structure.
