RESUMO
BACKGROUND AND AIMS: The impact of hepatitis C virus (HCV) eradication via direct-acting antiviral (DAA) therapy on overall mortality, particularly non-liver-related mortality, is understudied. METHODS: We recruited 4180 patients with chronic HCV infection who achieved sustained virological response (SVR) (HCV eradication) through DAA therapy (n = 2501, SVR group) or who did not receive antiviral therapy (n = 1679, non-SVR group); 1236 from each group were chosen using propensity score matching. Causes of death and all-cause mortality, including non-liver-related diseases, were investigated. RESULTS: Of the 4180 patients, 592 died during the follow-up period. In the SVR group, the mortality rates from liver-related and non-liver-related diseases were 16.5% and 83.5%, respectively. Compared to the non-SVR group, mortality rates from liver-related and non-liver-related diseases were 50.1% and 49.9%, respectively (p < .001). In non-cirrhotic patients, multivariable analysis revealed that SVR was an independent factor associated with both liver-related (hazard ratio [HR], .251; 95% confidence interval [CI], .092-.686) and non-liver-related (HR, .641; 95% CI, .415-.990) mortalities. In cirrhotic patients, multivariable analysis revealed that SVR remained an independent factor significantly associated with liver-related mortality (HR, .151; 95% CI, .081-.279). In propensity score-matched patients, the eradication of HCV (SVR group) decreased both liver-related (p < .001) and non-liver-related mortality (p = .008) rates compared to persistent HCV infection (non-SVR group). CONCLUSIONS: The elimination of HCV via DAA therapy reduced not only liver-related mortality but also non-liver-related mortality in patients with chronic HCV.
RESUMO
A 47-year-old woman was referred to our hospital with recurring lower abdominal pain persisting for more than 2 weeks. Imaging modalities showed small bowel obstruction caused by a mass lesion in the terminal ileum. Despite undergoing fasting, rehydration, and decompression through an ileus tube, her symptoms persisted. Furthermore, the condition deteriorated on day 4, with the onset of her menstrual period. An emergency surgery was conducted on the 7th day after hospitalization. Surgical observations indicated severe stenosis around the ileocecal valve and ileal perforation approximately 40cm from the oral stricture. As a result, ileocecal resection was performed. Pathological examination revealed endometrial tissue infiltration through the mucosal lamina propria to the ileal subserosa. Thus, the patient was identified with intestinal endometriosis of the ileocecum. Endometriosis of the small bowel is an uncommon condition that eventually causes intractable bowel obstruction. Although preoperative diagnosis is considered challenging, intestinal endometriosis should be included in the differential diagnosis in cases of bowel obstruction in women of childbearing age.

BACKGROUND: Thrombocytopenia due to hypersplenism is a major complication of hepatitis C virus (HCV)-associated cirrhosis. HCV eradication improves these complications in some patients, but the long-term effects of HCV eradication on these complications remain unclear, especially in patients treated with direct acting antivirals (DAAs). The aim was to evaluate long term changes in thrombocytopenia and leucopenia after HCV eradication with DAAs. METHODS: The present multicenter study retrospectively evaluated changes over 5 years in thrombocytopenia and leukocytopenia, as well as changes in liver fibrosis markers and spleen size, in 115 patients with HCV-cirrhosis treated with DAAs. RESULTS: Thrombocytopenia and leukocytopenia were improved 4 weeks after DAA administration, with thrombocytopenia show further gradual improvement over the next year. Fib-4 index was markedly reduced 1 year after DAA, followed by subsequent gradual reduction over the next 4 years. Spleen size showed gradual annual reductions, with patients experiencing spleen size reduction characterized at baseline by bilirubinemia. CONCLUSIONS: Rapid DAA-associated HCV eradication might lead to rapid disappearance of liver inflammation and bone marrow suppression due to HCV infection. HCV eradication may gradually improve portal hypertension, reducing spleen size.

Improvements in the hepatocellular carcinoma (HCC) recurrence rate and survival have been frequently reported following virus eradication after hepatitis C virus (HCV)-related HCC cure. However, the efficacy of direct-acting antiviral (DAA) therapy in patients who included those with advanced HCC and decreased hepatic functional reserve is unknown. A comparative examination was retrospectively conducted of 141 patients with hepatitis C who started DAA therapy within 1 year after undergoing curative HCC treatment and showed a sustained viral response (SVR) and 327 patients who underwent curative treatment for HCV-related HCC and did not subsequently receive antiviral therapy. Whether DAA therapy was given was identified as an independent factor related to both HCC recurrence and survival. Both the recurrence and survival rates improved significantly with DAA therapy in Child-Pugh (CP)-A, whereas no difference in the recurrence rate was seen with DAA therapy in CP-B. However, the survival rate was significantly higher in the DAA group in this class. Similarly, dividing the patients by the Milan criteria showed significant improvements in the recurrence rate and survival with DAA therapy in patients within the Milan criteria. Patients with HCC beyond the Milan criteria showed no difference in recurrence rates, but the DAA group tended to have higher survival rates. Thus, DAA after curative therapy for HCC can be expected to improve survival in patients with advanced HCC or decreased hepatic functional reserve. HCV should be aggressively eradicated in all patients eligible for curative treatment of HCC.

A woman in her 70s was admitted to our hospital because of epigastric pain and anorexia. Laboratory evaluations revealed elevated levels of liver transaminases, biliary enzymes, and amylase. CT and MRCP showed dilatation of the bile and pancreatic ducts and a large juxtapapillary diverticulum filled with contents. There were no gallstones or tumors present. Our differential diagnosis included obstruction of the papilla of Vater, so we performed an urgent ERCP. Endoscopic examination showed the juxtapapillary diverticulum filled with food residue;however, we were unable to locate the papilla of Vater. We rinsed out and removed food residue from the diverticulum using a retrieval balloon catheter used for gallstones. After the endoscopic removal of the food residue, the patient's epigastric pain immediately subsided and her cholangitis and pancreatitis improved gradually.

AIM: The present study aimed to determine the real-world efficacy and safety of the non-structural protein (NS)5A inhibitor elbasvir (EBR) combined with the NS3/4A protease inhibitor grazoprevir (GZR) in patients with hepatitis C virus (HCV) genotype 1 (GT1) infection. METHODS: This study retrospectively evaluated the rate of sustained virologic response at 12 weeks post-treatment (SVR12) and the safety of EBR/GZR treatment in 159 men and 194 women with a median age of 72 years, and it assessed factors associated with the SVR12 rate. The attending physicians were responsible for selecting candidate patients for EBR/GZR in this retrospective study. RESULTS: Treatment outcomes for EBR/GZR were good in direct-acting antiviral (DAA)-naïve patients, of whom 99.4% achieved SVR. Of 353 patients, 10 (2.9%) had treatment failure. Of these patients, eight previously underwent DAA therapy, and the remaining two had NS5A-L31/Y93 double mutation. The SVR rate was 50% (8/16 patients) in patients who previously underwent DAA therapy, and 18.2% (2/11 patients) in patients with NS5A-L31/Y93 double mutation. On multivariate logistic regression analysis, NS5A-Y31/Y93 double mutation (odds ratio 356.3; 95% confidence interval, 23.91-16 940; P < 0.0001) was identified as an independent predictor of treatment failure. No serious adverse events were observed with EBR/GZR therapy. CONCLUSIONS: The SVR rate of EBR/GZR would have been 100% in patients without either a history of DAA therapy or double mutation. This combination of drugs could be safely given and is, thus, considered a highly useful first-line treatment for DAA-naïve patients with HCV.
RESUMO
AIM: To evaluate the virologic responses and clinical course of daclatasvir plus asunaprevir treatment in non-hemodialysis (non-HD) and hemodialysis (HD) patients infected with genotype 1 hepatitis C virus (HCV). METHODS: A total of 1113 non-HD patients and 67 HD patients were assessed. To evaluate pretreatment factors contributing to sustained virological response at 12 weeks (SVR12), univariate and multivariate analyses were carried out. To adjust for differences in patient background, propensity score matching was undertaken. RESULTS: The overall SVR12 rates were 91.6% in non-HD patients and 95.5% in HD patients. Compared with non-HD patients, HD patients were younger, were more likely to be male, were less likely to have received interferon-based pretreatment, had a lower viral load, and had lower levels of alanine transaminase, hemoglobin, and α-fetoprotein. Multivariate analysis revealed that viral load, α-fetoprotein, L31 substitution negative, and Y93 substitution negative were independent predictive factors for SVR12 in non-HD patients. The proportion of patients with undetectable HCV-RNA during the initial 4 weeks was significantly higher in HD patients than in non-HD patients. The SVR12 rate was clearly higher in HD patients than in non-HD patients, although the difference was not statistically significant. After propensity score matching to adjust for viral load, α-fetoprotein, L31 substitution, and Y93 substitution, these trends disappeared. CONCLUSIONS: For treatment of HCV genotype 1 infection, daclatasvir plus asunaprevir is useful not only in non-HD patients but also in HD patients. Viral load, α-fetoprotein levels, L31 substitution, and Y93 substitution influence treatment course and outcome.
RESUMO
Background and aim: In patients with chronic hepatitis C, 8 weeks of glecaprevir and pibrentasvir (GLE/PIB) treatment for chronic hepatitis (non-cirrhosis) and 12 weeks for cirrhosis have been approved in Japan. However, whether 8 weeks of treatment for cirrhosis may reduce treatment efficacy has not been adequately investigated. Methods: This prospective, nationwide, multicenter cohort study enrolled 1275 patients with chronic hepatitis C who received GLE/PIB therapy. The effect of liver fibrosis and treatment periods on the efficiency of GLE/PIB therapy was investigated. The primary endpoint was the sustained virological response (SVR) rate in patients with chronic hepatitis (non-cirrhosis) and cirrhosis. The association between treatment periods and liver fibrosis on the SVR after 12 weeks of treatment rate was investigated. Results: The SVR rates in patients with chronic hepatitis with 8 weeks of treatment, chronic hepatitis with 12 weeks of treatment, cirrhosis with 8 weeks of treatment, and cirrhosis with 12 weeks of treatment were 98.9% (800/809), 100% (87/87), 100% (166/166), and 99.1% (211/213), respectively, and were was not different among these groups (P = 0.4). Conclusion: GLE/PIB therapy for chronic hepatitis C had high efficacy regardless of liver fibrosis status and treatment periods. Periods of GLE/PIB therapy could be chosen with available modalities, and high SVR rates could be achieved regardless of the decision.
RESUMO
We herein report a case of glossopharyngeal neuralgia with repeated syncope caused by the recurrence of esophageal carcinoma. The typical symptoms of glossopharyngeal neuralgia are paroxysmal, stabbing, electric shock-like pain in the pharynx and/or base of the tongue on swallowing and talking. In addition, syncope can also be caused by glossopharyngeal neuralgia. The diagnosis of glossopharyngeal neuralgia is not always easy because of its rarity. In the present case, we suspected that repeated syncope was caused by glossopharyngeal neuralgia due to the recurrence of esophageal carcinoma. Concurrent chemoradiation therapy was effective in reducing the tumor size, which resulted in the complete resolution of the symptoms.

BACKGROUND AND AIM: This study aimed to elucidate whether interferon (IFN)-free direct-acting antiviral (DAA) therapy for hepatitis C after curative treatment of hepatocellular carcinoma (HCC) promotes HCC recurrence in a real-world large-scale cohort. METHODS: This multicenter study was conducted by the Japanese Red Cross Hospital Liver Study Group. This retrospective study analyzed 516 patients who underwent antiviral treatment for hepatitis C with either IFN (n = 148) or IFN-free DAA (n = 368) after curative HCC treatment; 78 IFN-treated patients and 347 IFN-free DAA-treated patients achieved sustained virological response (SVR). The recurrence rate of HCC was compared between the antiviral therapies. Logistic analysis and Cox proportional hazards analysis identified factors associated with early recurrence of HCC within 24 weeks of antiviral therapy and recurrence throughout the observation period, respectively. RESULTS: AFP at the completion of antiviral therapy, clinical stage of HCC, and non-SVR were independent factors associated with early recurrence of HCC. Among patients who had achieved SVR, the clinical stage of HCC and the level of AFP at completion of antiviral therapy were independent factors associated with early recurrence of HCC. For recurrence throughout the observation period in SVR patients, AFP at completion of antiviral therapy, duration between last HCC treatment to antiviral therapy, and the number of treatments were independent factors. There was no significant difference in the rate of early recurrence of HCC or recurrence throughout the observation period between IFN and IFN-free DAA treated patients. CONCLUSIONS: There were no differences in the early recurrence rate of HCC between patients who underwent IFN and those who underwent IFN-free DAA as antiviral therapies.

A 47-year-old Japanese man was first admitted to our hospital for 8 days because of an asthma attack. After discharge he changed his diet. On the 12th day after his discharge, he was re-admitted to our hospital because he exhibited transient loss of consciousness with flapping tremor. His plasma ammonia level was extremely high (245 µg/dL; normal, <90 µg/dL), suggesting hepatic encephalopathy. He underwent intravenous administration of branched-chain amino acids (Aminoleban(®)) and oral administration of lactulose and kanamycin sulfate; however, the hyperammonemia did not improve. Analysis of the amino acids and citrin gene led to the diagnosis of adult-onset type II citrullinemia (CTLN2). Following this diagnosis, the carbohydrate content of his diet was mildly restricted. As a result, his plasma ammonia level markedly improved (ammonia, 40-60 µg/dL) and he became symptom-free without any medication. CTLN2 is a metabolic disorder characterized by increased plasma concentrations of citrulline and ammonia, which occurs by the failure of compensatory mechanisms associated with diet. Here, we report a case of a patient for whom a change in eating habits during his hospitalization disturbed his compensatory mechanism resulting in clinical CTLN2, which was reversed with an appropriate diet.

BACKGROUND/AIMS: Idiosyncratic immune response to drugs causes two types of liver injury, cholestasis or hepatitis. However, the underlying immune mechanisms of drug-induced liver injury are presently unclear. METHODS: We examined the cytokine production of peripheral blood mononuclear cells (PBMCs) from 17 patients with drug-induced liver injury and healthy controls during their incubation with and without the drug by flow cytometry. We also analyzed the cytokine production in PBMCs from eight patients after stimulation with the drug-pulsed HepG2 lysates to examine the possibility that the drug or its metabolites conjugated with a putative molecule derived from HepG2 cells might be more immunogenic. RESULTS: Among several cytokines produced by the drug or the drug-pulsed HepG2 lysates, interferon-gamma production from CD8+ cells was associated with hepatocellular injury, and tumor necrosis factor-alpha production from CD14+ cells was with cholestasis. Especially, the latter was apparent when the drug-pulsed HepG2 lysates were used as stimulants, suggesting that a complex consist of the drug, or its metabolite, and a putative molecule derived from HepG2 cells might be more immunogenic than the drug itself. CONCLUSIONS: The analysis of intracytoplasmic cytokine in PBMCs after stimulation with the drug or the drug-pulsed HepG2 lysates is useful to analyze the immune mechanism underlying drug-induced liver injury.
