Special Issue Information

Dear Colleagues,

Chronic inflammatory illnesses and autoimmune disorders represent a major global health issue, characterised by persistent inflammation and immunological dysregulation, which can cause severe tissue damage and a lower quality of life. Despite advances in immunomodulatory therapy, current medications frequently have limited efficacy and serious adverse effects, emphasising the need for innovative therapeutic methods. This Special Issue will investigate cutting-edge solutions in the prevention and treatment of chronic inflammatory and autoimmune illnesses, with an emphasis on molecular and cellular advances. A focus will be placed on innovative biologics, small-molecule inhibitors, gene editing technologies, and cell-based therapeutics such as mesenchymal stem cells and modified immune cells that target key inflammatory pathways. Furthermore, this Special Issue will investigate the effect of gut microbiota manipulation, nanoparticle-based drug delivery methods, and personalised medicine techniques in improving therapy specificity and patient outcomes. Contributions that investigate the molecular pathways underlying disease aetiology, biomarker identification for early diagnosis, and clinical trial data on developing therapeutics are also welcome. Our aim is to create a comprehensive forum where academics and doctors can share recent progress, with the ultimate goal of transforming new research into better and safer therapeutic alternatives for patients. This Special Issue will promote interdisciplinary collaboration and close the gap between basic research and clinical applications in the field of chronic inflammatory and autoimmune disease management.

A subset of patients with inflammatory bowel disease (IBD) remains refractory to treatment despite multiple lines of advanced therapies. These patients are often categorized as having difficult-to-treat (DTT) IBD. We retrospectively analyzed 354 patients with IBD (including 112 with Crohn’s disease [CD] and 242 with ulcerative colitis [UC]) from a real-world cohort. Baseline demographic and disease characteristics, treatment history, and outcomes were compared between the DTT-IBD and non-DTT-IBD groups. Logistic regression analysis was performed to identify factors associated with DTT-IBD in CD and UC cohorts. Approximately 10.6% of the patients exposed to advanced therapy fulfilled the definition of DTT-IBD (CD: 9.8%, UC: 11.4%). Compared with patients with non-DTT-IBD, those with DTT-IBD exhibited a significantly higher exposure to multiple biologic classes, including antitumor necrosis factor (94.1% vs. 59.0%), anti-integrin (94.1% vs. 47.2%), anti-interleukin-12/23 (88.2% vs. 19.4%), and Janus kinase inhibitors (35.3% vs. 0.7%). The DTT-IBD group had a significantly lower clinical remission rate at the last follow-up than the non-DTT-IBD group (52.9% vs. 85.4%, p = 0.001). A longer interval from diagnosis to the initiation of advanced therapy was independently associated with DTT-IBD in CD (OR: 1.014 per month, 95% CI: 1.001–1.026, p = 0.026). No significant predictors for UC were identified. In conclusion, DTT-IBD, characterized by extensive biologic exposure and suboptimal long-term remission rates, accounts for approximately 10% of patients with IBD receiving advanced therapy. In CD, delayed initiation of advanced therapy may contribute to refractoriness. These findings emphasize the unmet need for earlier therapeutic intervention, better predictive markers of treatment response, and novel therapeutic mechanisms. Full article

Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn’s disease (CD), is a chronic, immune-mediated inflammatory disorder of the gastrointestinal tract. Immunosuppressive therapy administration increases the risk of hepatitis B virus (HBV) and hepatitis C virus (HCV) reactivation. This study aimed to investigate the hepatitis screening rate, serological status, and protective antibody levels among the Taiwanese IBD population. This single-center retrospective study included patients with IBD from January 2016 to December 2024. Hepatitis serological markers were analyzed. Patients were categorized into active HBV infection (HBsAg-positive), resolved HBV infection (HBsAg-negative and anti-HBc-positive), and non-HBV-infected groups, with prevalences of 7.5%, 32.5%, and 0.9%, respectively. This study included 347 patients with IBD (UC: 68.3%; CD: 31.7%), with a mean age of 47.1 ± 16.4 years. Patients born after 1984 demonstrated a significantly reduced HBsAg positivity (0.9% vs. 11.0%; p < 0.05) and resolved HBV infection (52.2% vs. 1.0%; p < 0.05). However, among non-HBV-infected individuals, only 42.0% had protective anti-HBs levels (≥10 mIU/mL), despite vaccination program initiation. In this study, we found an overall HBsAg positivity rate of 7.5% and an anti-HCV seropositivity rate of 0.9% in our IBD population. Taiwan’s HBV vaccination program has effectively reduced the HBV prevalence. However, a significant proportion of vaccinated individuals lack sufficient protective antibody levels, thereby requiring continued HBV screening and booster vaccinations. Full article

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that severely impairs quality of life. Treatment typically involves a patient-oriented combination of medical therapies, surgery, and lifestyle modifications. However, data on the impact of surgical treatments on quality of life remain limited. This prospective monocentric study aimed to evaluate the effect of wide surgical excision in patients with moderate to severe HS (Hurley stage II/III) who were naïve to systemic biologic treatments. Between March 2017 and November 2022, 82 patients (51% female; 80% Hurley II, 20% Hurley III) underwent major surgical excision. Assessments were performed before surgery and at three and six months postoperatively. The primary endpoint was the change in Dermatologic Life Quality Index (DLQI); secondary endpoints included changes in pain (NRS-11) and disease severity scores. DLQI improved from 11.7 at baseline to 8.3 at three months and 4.7 at six months (p < 0.001). Pain scores and the modified Hidradenitis Suppurativa Score (mHSS) also significantly decreased (p < 0.001). In conclusion, major surgery significantly improved quality of life and pain in HS patients, confirming its essential role in a multimodal treatment approach. Patient-reported outcome measures are crucial for assessing treatment efficacy in HS. Full article

Chronic inflammatory diseases and autoimmune diseases are overlapping but distinct immune-mediated disorders that represent a growing worldwide health concern, characterised by persistent inflammation, tissue damage, and progressive organ dysfunction. In the United States alone, more than $180 billion is spent annually on managing these conditions, yet fewer than 10% of patients achieve long-term remission. These figures highlight the limitations of conventional therapies, which often control symptoms rather than adequately modify the underlying disease process. This review provides a focused and comparative overview of emerging therapeutic strategies across representative immune-mediated disorders, with particular emphasis on mesenchymal stem cells, Janus kinase-signal transducer and activator of transcription (JAK-STAT) inhibitors, chimeric antigen receptor T-cell therapies, therapeutic vaccines, microbiome-modulating interventions, and nanotechnology-based drug delivery systems. In parallel, artificial intelligence (AI) is increasingly contributing to biomarker discovery, drug repurposing, and treatment stratification, thereby supporting the development of predictive and personalised medicine. Overall, these advances support a shift toward mechanism-based, multimodal, and more durable treatment strategies, although further clinical validation remains necessary. Full article

HIV-associated neurocognitive disorders (HANDs) refer to a range of cognitive deficits that afflict people living with the Human Immunodeficiency Virus (HIV). The fundamental processes of HAND include persistent inflammation, immunological activation, and direct viral impact on the central nervous system. Emerging research shows that nutritional status, especially food consumption and body weight, is critical in determining the course and severity of HAND. Malnutrition exacerbates neurocognitive impairment by increasing inflammation and oxidative stress, while obesity may contribute to HAND through the promotion of metabolic disruption, gut microbiota alterations, and systemic inflammation. Additionally, the introduction of antiretroviral treatment (ART) has substantially enhanced the prognosis of people living with HIV by lowering viral load and improving immune function. However, depending on the regimen, ART can cause changes in body weight, which may influence the progression of HAND. This emphasizes the intricate interplay between HIV, nutrition, body weight, and neurocognitive health. As a result, various dietary approaches are currently being investigated to improve the quality of life of individuals with HIV and possibly help prevent neurocognitive decline in this population. This review aims to elucidate the relationship between nutrition and neurocognitive function in individuals living with HIV, shedding light on aspects of HANDs related to diet, body weight fluctuations, and metabolic syndrome. It explores the shift from current pharmacological treatments to innovative non-pharmacological interventions, including specific dietary strategies, to support overall health and cognitive well being in HIV-positive people.
