Zou X, Lu Y, Tan Y. Effect of serum metabolites on the risk of iridocyclitis: a bidirectional Mendelian randomization study. Sci Rep 2024; 14:10535.

Abstract
Previous research has linked serum metabolite levels to iridocyclitis, yet their causal relationship remains unexplored. This study investigated this potential causality by analyzing pooled data from 7824 iridocyclitis patients in a Genome-Wide Association Study (GWAS) using Mendelian randomization (MR) and linkage disequilibrium score regression (LDSC). Employing rigorous quality control and comprehensive statistical methods, including sensitivity analyses, we examined the influence of 486 serum metabolites on iridocyclitis. Our MR analysis identified 23 metabolites with significant causal effects on iridocyclitis, comprising 17 known and 6 unidentified metabolites. Further refinement using Cochran's Q test and MR-PRESSO indicated 16 metabolites significantly associated with iridocyclitis risk. LDSC highlighted the heritability of certain metabolites, underscoring genetic influences on their levels. Notably, tryptophan, proline, theobromine, and 7-methylxanthine emerged as risk factors, while 3,4-dihydroxybutyrate appeared protective. These findings enhance our understanding of the metabolic interactions in iridocyclitis, offering insights for diagnosis, unraveling pathophysiological mechanisms, and informing potential avenues for prevention and personalized treatment.

Abstract
INTRODUCTION Noninfectious uveitis represents one of the leading causes of blindness in developed Countries, compromising patients' quality of life and social functioning. The main treatment goals are the control of ocular inflammation, to avert and treat sight-threatening complications, thus preserving and/or restoring visual function. AREAS COVERED This manuscript deals with systemic therapy with biologic drugs for noninfectious uveitis. An extensive literature search in the MEDLINE database (via PubMed) has been performed up to June 2020. The major classes of biologic molecules employed in ocular inflammatory diseases have been reviewed, focusing on TNF inhibitors, IL-1, IL-6, IL-17, IL-23 inhibitors, interferons, rituximab, and abatacept efficacy and safety. An overview of most recent developments in the field has been provided as well, with reference to the experience with JAK inhibitors and with biosimilar drugs. EXPERT OPINION The development of the concept of targeted therapy and the subsequent introduction of biologic molecules in clinical practice have revolutionized the prognosis of uveitis. The target of a rapid and sustained steroid-free remission of ocular inflammation should be pursued for all patients early in the disease course, in order to have a better chance to improve the final visual outcome.

Abatacept treatment impairs the cell migration and wound healing of oral ulcers in rats: Role of interleukin (IL)-1β, -6 and -10 and CD8/CD30 cells: Influence of abatacept treatment on oral wound healing: Experimental model on rats. Life Sci 2020; 243:117243. [PMID: 31917994 DOI: 10.1016/j.lfs.2019.117243] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 12/19/2019] [Accepted: 12/27/2019] [Indexed: 12/01/2022]
Abstract
The present study aimed to evaluate the healing process of ulcers in the jugal mucosa of Wistar rats treated with abatacept. The rats were randomly assigned to four groups: saline-treated control (0.3 mL/kg) abatacept-treated groups at dosages of 3.2, 8.0 and 20.0 mg/kg/week. After two weeks of subcutaneous (SC) administration, ulcers were introduced into the left jugal mucosa with an 8-mm diameter punch. SC administration was continued until euthanasia (after 1, 3, 7, 14 and 21 days of ulceration), and ulcers were clinically measured and animals weighed. Histological slides were evaluated (healing scores and polymorphonuclear, mononuclear, vessel, and fibroblast/myofibroblast counts). We also performed collagenesis analysis (Picrosirius Red) and immunohistochemistry (induced nitric oxide synthase (iNOS), interleukin (IL)-1beta (1β), -6, -10, plus the analysis of CD8 and CD30). The experiment was repeated to perform a vascular permeability assay. ANOVA 1-way or 2-way/Bonferroni and Kruskal-Wallis/Dunn tests were used for statistical analysis (GraphPad Prism 5.0®, p < 0.05). Abatacept treatment reduced the ulcer diameter and the numbers of polymorphonuclear and mononuclear cells; reduced the CD8+/CD30+ ratio and vascular permeability; and increased collagenesis and IL-10 expression at the beginning of the protocol. At the highest dose, there was a delay in repair and vascular proliferation; a reduction in the number of fibroblasts/myofibroblasts; and prolongation of iNOS, IL- and IL- expression. We conclude that abatacept accelerates the healing of oral ulcers by reducing the migration of inflammatory cells, but overdose of abatacept leads to delayed repair and prolongation of proinflammatory cytokine expression.

Abstract
Uveitis is the third most common cause of blindness in developed countries. Considering the systemic and local complications of long-term corticosteroid therapy and the intolerance due to side effects and ineffectiveness of conventional chemotherapy, use of biologic response modifiers is a reasonable alternative in the treatment of non-infectious uveitis and persistent uveitic macular edema. The majority of the evidence presented here comes from open uncontrolled analyses. Based on these studies, tumor necrosis factor alpha inhibitors, especially infliximab and adalimumab, have been shown to be effective in the treatment of non-infectious uveitis in numerous studies. More research is necessary, particularly multi-center randomized clinical trials, to address the choice of biologic response modifier agent and the length of treatment as we employ biologic response modifiers in different types of uveitis and persistent uveitic macular edema.
