Among these, osteosarcopenia has emerged as a significant concern, characterized by the concurrent deterioration of bone density and muscle mass, strength, and function. This dual deterioration significantly elevates the risk of falls and fractures, thereby exacerbating morbidity and diminishing quality of life. The pathogenesis of IBD-associated osteosarcopenia is multifactorial, with chronic intestinal inflammation serving as a central driver. Pro-inflammatory cytokines simultaneously disrupt bone homeostasis and muscle metabolism, creating a catabolic environment that impacts both tissues. Nutritional deficiencies, common in IBD due to malabsorption and decreased dietary intake, further compromise both bone mineralization and muscle protein synthesis. Management requires a comprehensive approach combining nutritional optimization, structured physical therapy, and lifestyle modifications. Pharmacological interventions integrate diseasespecific treatments with targeted therapies including vitamin D supplementation, hormonal treatments, and bisphosphonates when indicated. This review synthesizes current evidence regarding the prevalence, pathogenesis, and clinical impact of osteosarcopenia in IBD, highlighting areas requiring further investigation.</p>","PeriodicalId":14481,"journal":{"name":"Intestinal Research","volume":" ","pages":"254-289"},"PeriodicalIF":3.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12332291/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144015674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Evolution of inflammatory bowel disease in Korea: a 60-year perspective on clinical and research development.","authors":"Suk-Kyun Yang","doi":"10.5217/ir.2025.00073","DOIUrl":"10.5217/ir.2025.00073","url":null,"abstract":"<p><p>Inflammatory bowel disease (IBD) was once considered rare in Korea, with the first reported case documented in 1961. Since then, its incidence and prevalence have increased markedly, accompanied by significant progress in clinical care and research. This narrative review traces the historical evolution of IBD in Korea, dividing the timeline into 4 periods: 1960-1979, 1980-1999, 2000-2019, and 2020-2039. For each period, major developments in the research environment and trends, diagnostic process, patient population and characteristics, and treatment are outlined. Over the past 6 decades, diagnostic and therapeutic approaches in Korea have advanced markedly, transitioning from limited diagnostic capacity and symptom-based management to practices that align with global standards. Notably, Korean patients with IBD exhibit distinctive clinical features compared with Western counterparts, including a markedly higher proportion of proctitis and a lower long-term risk of colectomy in ulcerative colitis, and a substantially higher prevalence of perianal fistulas in Crohn's disease, highlighting the need for population- specific strategies to advance personalized medicine. In parallel, the research landscape has evolved through multicenter collaborations, expanded research capacity, and growing international engagement, positioning Korea as an increasingly active contributor to the global IBD research community. Looking ahead, the future of IBD research in Korea is expected to be shaped by innovation-driven research, including advances in artificial intelligence, large-scale data integration, and deeper international collaboration. By tracing the clinical and research trajectory of IBD in Korea, this review offers insight into how the country has adapted to global trends and is preparing to meet future challenges.</p>","PeriodicalId":14481,"journal":{"name":"Intestinal Research","volume":" ","pages":"233-253"},"PeriodicalIF":3.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12332290/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144368858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
