Article Synopsis
  • A new case of anti-MDA5-positive dermatomyositis-associated rapidly progressive interstitial lung disease (DM-RPILD) was reported in a 75-year-old Japanese man after he received a sequence of COVID-19 infection followed by vaccinations.
  • *Prior cases of this condition had only been linked to COVID-19 vaccinations alone.
  • *The patient experienced multiple symptoms after receiving the pneumococcal vaccine, and despite treatment, his condition deteriorated and he passed away shortly thereafter.

Article Synopsis
  • The study compared the safety and effectiveness of apixaban replacement (AR) versus heparin bridging (HB) for patients on warfarin undergoing endoscopic mucosal resection (EMR) for colorectal polyps.
  • Conducted in Japan, the trial aimed to enroll 160 patients but only 44 were included due to a shortage of eligible participants; these were randomly assigned to either AR or HB groups.
  • Results showed that AR had no postoperative bleeding incidents compared to 15% in HB, along with a significantly shorter hospital stay for AR patients, suggesting AR might be a safer alternative despite the trial's limited sample size.

Although superficial non-ampullary duodenal epithelial tumor (SNADET) was previously considered a rare disease, in recent years, the opportunities to detect and treat SNADET are increasing. Considering the high morbidity of pancreatoduodenectomy, endoscopic resection can be a treatment option that preserves the organs and contributes maintain patients' quality of life. Endoscopic mucosal resection (EMR) is a standard treatment for relatively small lesions in gastrointestinal tracts, however, it is difficult because submucosal fibrosis frequently occurs due to the previous biopsy.

Since its introduction into clinical practice in 2000, capsule endoscopy (CE) has become an important procedure for many pathologies of small bowel (SB) diseases, including inflammatory bowel disease (IBD). Currently, the most commonly used capsule procedures are small bowel capsule endoscopy (SBCE), colon CE (CCE), and the recently developed pan-enteric CE that evaluates the SB and colon in patients with Crohn's disease (CD). SBCE has a higher diagnostic performance compared to other radiological and conventional endoscopic modalities in patients with suspected CD.

Background And Aim: Preoperative histological evaluation of pancreatic neoplasms is important for guiding the resection strategy and preventing postoperative adverse events. However, conventional endoscopic methods have technical limitations that reduce the accuracy of the histopathological examination. Probe electrospray ionization mass spectrometry (PESI-MS) may be a useful technique for rapidly evaluating small specimens.

Objectives: Large vessel vasculitis (LVV) is characterised by a high relapse rate. Because accurate assessment of the LVV disease status can be difficult, an accurate prognostic marker for initial risk stratification is required. We conducted a comprehensive longitudinal investigation of next-generation RNA-sequencing data for patients with LVV to explore useful biomarkers associated with clinical characteristics.

Background And Aim: Percutaneous endoscopic gastrostomy (PEG) has been used in patients with dysphagia and inadequate food intake via an oral route. Despite being a procedure with a high success rate, complications and death have been reported. The aim was to identify the factors related to major complications and mortality, as well as PEG removal prognostic factors due to improvement of their general condition.

Objectives: Tocilizumab (TCZ) is a humanised anti-interleukin (IL)-6 receptor (IL-6R) monoclonal antibody that is a promising agent to treat various autoimmune diseases. However, the mechanism of TCZ efficacy is unclear. This study aims to elucidate the relationship between Tregs and IL-6R blockade in autoimmunity-mediated renal disease based on a TCZ-treated cohort of patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and in an experimental model of crescentic glomerulonephritis (cGN).

Behçet's disease (BD) is thought to be elicited by triggers such as tuberculosis (TB) infection in individuals with genetically aberrant immune activity, although the exact pathogenesis remains unknown. Seven cases of BD thought to be triggered by TB have been reported to date. In all cases, Behçet's symptoms improved smoothly after starting TB treatment.

Controversies and debates remain regarding the best management of severe acute-onset autoimmune hepatitis (SA-AIH) due to the lack of useful outcome or complication prediction systems. We conducted this clinical practice-based observational study to clarify whether Chronic Liver Failure Consortium Organ Failure scores (CLIF-C OFs) and the computed tomography-derived liver volume to standard liver volume (CTLV/SLV) ratio at admission to a tertiary transplant center can predict outcomes and complications due to infection. Thirty-four consecutive corticosteroid-treated patients with SA-AIH from 2007 to 2018 were included.

Background And Aim: The incidence of non-alcoholic fatty liver disease (NAFLD) is increasing all over the world. NAFLD develops in patients with liver disease, including patients with autoimmune hepatitis (AIH). NAFLD and AIH have some similar laboratory and histological findings.

A prognostic system for acute liver failure (ALF) with a higher predictive value is urgently needed. The role of extracellular matrix (ECM) remodeling in ALF has not been fully elucidated. We hypothesized that serologic fibrosis markers, which reflect ECM remodeling, are predictive of ALF outcome at first presentation.

IgG4-related sclerosing disease (IgG4-RD) occasionally involves breast entity, which is often difficult to distinguish from malignant tumor, as both radiologically resembles. We report a case of a breast mass diagnosed as IgG4-related mastopathy (IgG4-RM) through needle biopsy, which responded well to glucocorticoid therapy. Unnecessary excision should be avoided.
