Idiopathic inflammatory myopathies (IIM) are a heterogeneous group of autoimmune diseases characterized by muscle involvement and various extramuscular manifestations. Interstitial lung disease (ILD) is one of the most common extramuscular manifestations of IIM and is associated with significant mortality and morbidity. The clinical phenotypes, treatment responses, and prognosis of IIM-ILD are significantly related to myositis-specific antibody (MSA) profiles, with some racial differences. The features associated with MSA in IIM-ILD could also be relevant to cases of ILD where MSA is present but does not meet the criteria for IIM. The anti-melanoma differentiation-associated gene 5 antibody is highly associated with rapidly progressive ILD (RP-ILD), especially in Asian populations, and with characteristic cutaneous manifestations, such as skin ulcers. Radiologically, ground-glass opacities, consolidations, and nonsegmental linear opacities were more predominant than reticular opacities and honeycombing. While the mortality rate is still around 30%, the prognosis can be improved with early intensive therapy with corticosteroids and multiple immunosuppressants. In contrast, anti-aminoacyl-tRNA synthetase (ARS) antibodies are associated with chronic ILD, although RP-ILD is also common. Patients with anti-ARS antibodies often show lung-predominant presentations, with subtle muscle and skin involvement. Radiologically, reticular opacities, with or without consolidation, are predominant and may progress to honeycombing over time. Combination therapy with corticosteroids and a single immunosuppressant is recommended to prevent relapses, which often lead to a decline in lung function and fatal long-term outcomes. Significant advances in immunology and genetics holds promise for fostering more personalized approaches to managing IIMILD.

Background/Aims: Bowel urgency is an important symptom for quality of life determination in patients with ulcerative colitis (UC). Few clinical studies have focused on bowel urgency as an efficacy endpoint. Budesonide foam enema has shown efficacy for clinical and endoscopic improvement in mild-to-moderate UC. We evaluated the improvement of clinical symptoms (bowel urgency), safety, and treatment impact of twice-daily budesonide foam enema on the quality of life in patients with UC. Methods: This open-label, multicenter, prospective observational study comprised a 4-week observation period assessing the effectiveness and safety of twice-daily budesonide foam enema. Mild-to-moderate UC patients who had bowel urgency were included. Patients collected data daily in an electronic patient-reported outcome system or logbooks. The primary endpoint was the rate of resolution of bowel urgency at the end of the 4-week observation period. The rate of bowel incontinence was also assessed. Results: Sixty-one patients were enrolled. Of patients with a final evaluation, the rate of resolution of bowel urgency was 58.5% (31/53; 95% confidence interval, 44.1%–71.9%). Bowel urgency decreased over time, with a significant difference observed on day 7 versus day 0. Bowel incontinence showed a decreasing trend from day 5, with a significant difference confirmed on day 12 versus day 0. The clinical remission rate was 64.4% (38/59; 95% confidence interval, 50.9%–76.4%). One adverse event not related to budesonide rectal foam occurred. Conclusions The findings suggest that bowel urgency can be improved early with twice-daily budesonide foam enema. No new safety signals were observed.

Background/Aims: The efficacy and safety of endoscopic submucosal dissection using a clutch cutter (ESD-CC) for subepithelial lesions within the esophagogastric submucosa (SELEGSM) has not been investigated. This study aimed to assess the efficacy and safety of ESD-CC for the treatment of SELEGSM. Methods: This prospective study included 15 consecutive patients with 18 SELEGSMs diagnosed by endoscopic ultrasonography. The primary outcomes were short-term outcomes including en bloc resection rate, R0 resection rate, procedure time, and complication rate. The secondary outcome was final histological diagnosis. Results: Among the participants, 18 lesions were identified: 12 in the stomach (nine patients) and six in the esophagus (six patients). The en bloc resection rate was 94.4% (17/18). The R0 resection rate was 88.9% (16/18). The median operating time was 39 min, and no instances of perforation or bleeding were observed. The final diagnoses of SELEGSM included six neuroendocrine tumors (33.3%), six granular cell tumors (33.3%), two ectopic pancreases (11.1%), one inflammatory fibroid polyp (5.6%), one leiomyoma (5.6%), one lipoma (5.6%), and one leiomyosarcoma (5.6%). Conclusions ESD-CC appears to be a technically efficient and safe approach for SELEGSM resection, suggesting its potential as a valuable treatment option.
