Background & Aims Hepatitis C virus (HCV) infection has been known to cause various extrahepatic autoimmune disorders. The prevalence of platelet‐associated immunoglobulin G (PA‐IgG) has been high in patients with HCV infection. Because thrombocytopenia in HCV‐related liver diseases is a notable problem, we performed prospective study on the effect of direct‐acting antivirals (DAAs) treatment on PA‐IgG and platelet count. Methods A total of 215 patients with HCV‐related liver disease were enrolled in this study. The patients who discontinued DAAs or did not undergo adequate laboratory examinations and who did not achieve sustained virologic response were excluded and finally a total of 187 patients were investigated. Results A total of 171 patients (91.4%) were PA‐IgG positive (>46 ng/107 cells) before starting DAAs (baseline). The PA‐IgG level elevation was significantly correlated with higher liver inflammation and fibrosis markers (P < 0.05) and lower platelet count (P = 0.000019). The platelet count of the patients with low PA‐IgG titer tended to be higher at baseline, end of treatment (EOT), and at 12 and 24 weeks after EOT. The platelet count increased at EOT (P < 0.05) and 24 weeks after EOT (P < 0.01). The PA‐IgG levels were significantly decreased at EOT, 12 and 24 weeks after EOT (P < 0.01). Multiple regression analysis found that only platelet count at baseline was closely associated with negative conversion of PA‐IgG at 24 weeks after EOT (P = 0.004). Conclusions Eradication of HCV by DAAs treatment successfully decreased PA‐IgG level and increased platelet count.
Objectives: Esophageal variceal bleeding can be fatal in patients with liver cirrhosis. The aim of this study was to investigate the relationship between gastroesophageal flap valve (GEFV) and esophageal variceal bleeding. Methods: Subjects were cirrhotic patients with endoscopically diagnosed esophageal varices treated at our hospital between 2005 and 2019, excluding those with F3 form and red color (RC) signs at first endoscopy. Sixty-five patients with normal GEFV (Hill grade I or II) and 42 with abnormal GEFV (Hill grade III or IV) were enrolled. Propensity score matching eliminated the baseline differences, resulting in a sample size of 30 patients per cohort. The primary endpoint was esophageal variceal bleeding, and the secondary endpoint was variceal bleeding or appearance of RC sign. We analyzed the cumulative incidences and predictors of each endpoint. Results: The 3-, 5-, and 10-year cumulative incidences of the primary endpoints were all 3.4% in the normal GEFV group, and 19.0%, 24.6% and 34.0% in the abnormal GEFV group, respectively (log-rank P = 0.011). Cumulative incidence of the secondary endpoint was 13.8%, 33.1% and 39.2% in the normal GEFV group, and 42.2%, 54.6% and 84.9% in the abnormal GEFV group, respectively (log-rank P = 0.001). In multivariate Cox regression analyses, hazard ratios of abnormal GEFV of the primary and secondary endpoints were 12.79 (95% confidence interval 1.331-122.8) and 3.600 (1.653-7.840), respectively. Conclusions: Abnormal GEFV was an independent risk factor for esophageal variceal bleeding and appearance of RC sign.
Liver function is a most important prognostic factor in patients with liver cirrhosis. Also, portal hypertension is a fatal complication of liver cirrhosis and variceal treatment is indispensable. However, changes of liver functions after endoscopic variceal treatments are unknown. The aim of this study was to evaluate prognosis and liver functions after endoscopic injection sclerotherapy (EIS) and endoscopic variceal ligation (EVL). A total of liver cirrhotic 103 patients who underwent prophylactic EIS and EVL were enrolled. Overall survival rate was higher in EIS group than EVL group (p = 0.03). Multivariate analysis showed that EIS was a negative factor for death (HR: 0.46, 95% confidence interval: 0.24–0.88, p = 0.02). Liver functions were assessed by blood test taken at before and 3 months after treatment. In EIS group, albumin and prothrombin time improved (p < 0.01), leading to improvement of Child–Pugh score, ALBI score and MELD score (p < 0.05). However, these did not improve in EVL group. EIS was a significant factor related to the elevated value of albumin after treatment in linear regression analysis (estimated regression coefficient: 0.17, 95% confidence interval: 0.05–0.29, p = 0.005). These results revealed that EIS could improve liver functions and prognosis.
Cronkhite-Canada syndrome (CCS) is a rare non-inherited disease characterized by gastrointestinal polyposis, chronic diarrhea, ectodermal dysplasia, skin hyperpigmentation, hair loss and nail atrophy. Although the efficacy of corticosteroid and immunomodulatory agents has been demonstrated, no standard therapy regimen has been established, and the prognosis of CCS is still poor due to various complications. We here in report a CCS patient complicated with severe sepsis and disseminated intravascular coagulation who was successfully treated by combined modality therapies, including recombinant human soluble thrombomodulin.
Objectives The pathological diagnosis of endoscopically resected early gastric cancer (EGC) is performed by evaluating a few representative sections from the specimen. We aimed to determine whether evaluating twice as many sections as usual by essentially cutting the original sections in half could improve the pathological diagnosis of EGC. Methods We retrospectively investigated 85 EGC in 82 patients who had undergone endoscopic resection at our hospital from August 2008 to October 2012. EGC without indications of curative resection were excluded. We re‐examined the original paraffin blocks after shaving away approximately half their original thickness, and evaluated whether the pathological diagnoses were affected. This technique essentially doubled the number of sections examined. Results Ten pathological diagnoses of 68 EGC (14.7%) were changed from curative resection to non‐curative resection when we evaluated twice as many sections as in the standard method. The median tumor size was 25 mm in the changed diagnosis group versus 14.5 mm in the no change group (P = 0.03). The univariate analysis also showed that tumor size was a significant predictor of changed diagnosis (P = 0.015). Both the changed diagnosis group and no change group had no recurrence during follow up. Conclusions Histological evaluation of twice as many sections as usual changed the initial pathological diagnosis of EGC, although the clinical implication of an additional deeper section was controversial because there was no recurrence. Our analysis also emphasized the importance of detailed histological evaluation to confirm a radical cure in endoscopic resection, especially in the case of larger EGC.
