BACKGROUND: Sarcopenia is common in patients with autoimmune diseases (ADs); however, the causal associations between ADs and sarcopenia remain unclear. Therefore, this study investigated the causal associations using bi-directional Mendelian randomization analysis. METHODS: Exposure-related single-nucleotide polymorphisms (SNPs) were extracted from genome-wide association studies (GWASs). GWAS statistics for common ADs [Crohn's disease (CD), ulcerative colitis (UC), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), psoriasis (PSO), and multiple sclerosis (MS)] and sarcopenia-related traits [hand grip strength (HGS), appendicular fat-free mass (FFM), and walking pace] were obtained from public datasets...

Purpose To determine the etiology and anatomic localization of uveitis, the frequency of intraocular pressure (IOP) elevation, and the type of secondary glaucoma and to assess the medical, surgical, and postoperative complications in adult and pediatric patients with acute or chronic uveitis. Methods A total of 307 eyes of 186 patients who were followed up in the Uvea-Behçet Unit of the Ophthalmology Department, Erciyes University, Turkey, were included in the study. Demographic, ocular, and systemic data were recorded; ophthalmological examinations were performed; and recurrences and complications of uveitis were identified...

BACKGROUND: Ineffective drug treatment is a major problem for many patients with immune-mediated inflammatory diseases (IMIDs). Important reasons are the lack of systematic solutions for drug prioritisation and repurposing based on characterisation of the complex and heterogeneous cellular and molecular changes in IMIDs. METHODS: Here, we propose a computational framework, scDrugPrio, which constructs network models of inflammatory disease based on single-cell RNA sequencing (scRNA-seq) data...

BACKGROUND: Recent data suggest a potential pathophysiological link between inflammatory bowel disease (IBD) and multiple sclerosis (MS), two immune-mediated diseases both of which can have a significant impact on patients' quality of life. In the present manuscript, we investigate the association between IBD and MS in a German cohort of general practice patients. These results may have important implications for the screening and management of patients with IBD, as well as for further research into the pathophysiological mechanisms underlying both disorders...

(1) Background: Inflammatory bowel diseases (IBDs) are chronic inflammatory disorders involving innate and adaptive immune responses. Despite primarily affecting the gut, recent insights highlight systemic implications, expanding our understanding beyond intestinal boundaries. (2) Methods: This retrospective multicentric study explored the association of IBD and immune-mediated inflammatory diseases (IMIDs) and the impact of concurrent IMIDs on the course of IBD. Clinical data were collected from consecutive medical records of patients with IBD...

Teriflunomide (TFN) is an oral Disease-modifying therapy (DMT) widely used in the treatment of relapsing forms of Multiple Sclerosis (MS). Although TFN has demonstrated efficacy in reducing MS activity, recent evidence suggests a possible association between TFN and the onset of rare and severe medical conditions. We present a novel case report of a 47-year-old woman with a history of MS who developed concurrent Crohn's disease and Psoriasis following TFN treatment. This unique occurrence has not been previously documented in the literature...

BACKGROUND: Previous epidemiologic studies have suggested a linkage between the occurrence of multiple sclerosis (MS), Hodgkin lymphoma (HL), Crohn's disease (CD), and ulcerative colitis (UC). It was hypothesized that the 4 diagnoses would be characterized by similar geographic distributions within the United States. AIMS: To compare the US geographic distributions of these 4 diagnoses in a cross-sectional study. METHODS: Using the US vital statistics, state-specific death rates and age-specific proportional mortality ratios (PMR) were calculated for each diagnosis...

BACKGROUND: Autoimmune diseases exhibit heterogenous dysregulation of pro-inflammatory or anti-inflammatory cytokine expression, akin to the pathophysiology of sepsis. It is speculated that individuals with autoimmune diseases may have an increased likelihood of developing sepsis and face elevated mortality risks following septic events. However, current observational studies have not yielded consistent conclusions. This study aims to explore the causal relationship between autoimmune diseases and the risks of sepsis and mortality using Mendelian randomization (MR) analysis...

INTRODUCTION: With the global aging population on the rise, age-related macular degeneration (AMD) poses a growing healthcare burden. Prior research hints at immune-mediated inflammatory diseases (IMIDs) potentially elevating AMD risk via diverse mechanisms. However, causality remains disputed as a result of confounding factors. Hence, our Mendelian randomization (MR) study aims to untangle this link, mitigating confounding effects to explore the IMID-AMD causal relationship. This study aims to investigate the causal relationship between IMIDs and AMD, providing new strategies for the prevention and treatment of AMD in clinical practice...

BACKGROUND: Several studies investigated the risks of neurological conditions in patients with inflammatory bowel disease (IBD), with some variability in findings. We aimed to perform a systematic review and meta-analysis of available evidence to elucidate the association between IBD and the risks of common neurological disorders. METHODS: We conducted a literature search through Embase, PubMed, Scopus, and ProQuest databases from inception to June 30, 2023, to identify cohort studies assessing the risk of developing stroke, all-cause dementia, Parkinson's disease (PD), multiple sclerosis (MS), seizure/epilepsy, and peripheral neuropathy in adult IBD patients compared with non-IBD population...

Hematopoietic stem cell transplantation (HSCT) for severe ADs was developed over the past 25years and is now validated by national and international medical societies for severe early systemic sclerosis (SSc) and relapsing-remitting multiple sclerosis (MS) and available as part of routine care in accredited center. HSCT is also recommended, with varying levels of evidence, as an alternative treatment for several ADs, when refractory to conventional therapy, including specific cases of connective tissue diseases or vasculitis, inflammatory neurological diseases, and more rarely severe refractory Crohn's disease...

Autoimmune disorders represent a heterogeneous spectrum of conditions defined by an immune system's atypical reactivity against endogenous constituents. In the complex anatomy of autoimmune pathogenesis, lncRNAs have appeared as pivotal arbiters orchestrating the mechanisms of ailment initiation, immune cascades, and transcriptional modulation. One such lncRNA, MALAT1, has garnered attention for its potential association with the aetiology of several autoimmune diseases. MALAT1 has been shown to influence a wide spectrum of cellular processes, which include cell multiplication and specialization, as well as apoptosis and inflammation...

INTRODUCTION: Cannabinoids are a well-documented treatment modality for various immune and inflammatory diseases, including asthma, chronic obstructive pulmonary disease, Crohn's disease, arthritis, multiple sclerosis, and a range of neurodegenerative conditions. However, limited information is available regarding the therapeutic potential of cannabinoids in treating periodontal disease. OBJECTIVE: The objective of this study is to analyze the current evidence on the antibacterial and immunomodulatory effects of cannabis and its role in the healing and regeneration processes within periodontal tissues...

AIMS: Ocrelizumab is a humanized anti-CD20-monoclonal antibody that has recently been approved for the treatment of certain types of multiple sclerosis. Isolated case reports of ocrelizumab-associated colitis have been reported in the literature. We present a case series of ocrelizumab-associated intestinal injury with a focus on histopathologic features and report a case of ocrelizumab-associated hepatitis. METHODS AND RESULTS: A retrospective computerized search was conducted from 03/2017 to 08/2022, which identified six patients with suspected or clinically confirmed ocrelizumab-associated intestinal injury and one patient with hepatic injury...

OBJECTIVE: Previous studies have reported a possible prodrome in multiple sclerosis (MS) defined by non-specific symptoms including mood disorder or genito-urinary symptoms and increased health care use detected several years before diagnosis.This study aimed to evaluate agnostically the associations between diseases and symptoms diagnosed in primary care and the risk of multiple sclerosis (MS) relative to controls and two other autoimmune inflammatory diseases with similar population characteristics, namely lupus and Crohn's disease...

BACKGROUND AND AIMS: Epidemiologic evidence suggests that Hodgkin lymphoma (HL) and multiple sclerosis (MS) share a common set of risk factors with Crohn's disease (CD) and ulcerative colitis (UC). It was hypothesized that such shared risk factors would lead to clustering of the 4 diagnoses in the same patients. METHODS: All patients with HL, MS, CD, or UC were identified in the veterans population from 2016-2020 and the Medicare population from 1986 to 1989. In a case-control study, the observed concurrences amongst these 4 diagnoses were compared with their expected frequencies in the overall veterans or Medicare population during the same time period by calculating odds ratios (OR) with their 95% confidence intervals (CI)...

Lanthionine synthetase C-like 2 (LANCL2) therapeutics have gained increasing recognition as a novel treatment modality for a wide range of autoimmune diseases. Genetic ablation of LANCL2 in mice results in severe inflammatory phenotypes in inflammatory bowel disease (IBD) and lupus. Pharmacological activation of LANCL2 provides therapeutic efficacy in mouse models of intestinal inflammation, systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, and psoriasis. Mechanistically, LANCL2 activation enhances regulatory CD4 + T cell (Treg) responses and downregulates effector responses in the gut...

The development of Monoclonal antibodies (mAbs) has also allowed researchers to understand the complexity of diseases better and find new treatments for difficult-to-treat conditions. Using mAbs, researchers can identify and target specific molecules in the body involved in the disease process. This has allowed for a more targeted treatment approach, which has resulted in improved outcomes for many patients. This hypothesis has been the basis for the development of mAbs that can target an array of illnesses...
