Research progress on serological indices and their clinical application in rheumatoid arthritis

BackgroundAs a chronic systemic autoimmune disease of undetermined etiology, rheumatoid arthritis (RA) has a complex pathogenesis, which involves multiple proteins and cytokines. The 2010 ACR/EULAR classification criteria facilitate early diagnosis of RA with reduced specificity when compared to the 1987 ACR criteria. Hence, it is imperative to identify novel serological inflammatory indicators and targets, in order to explain the complex regulatory network of RA. The present review discusses the associations of various inflammatory factors with RA and its underlying mechanism. Besides, the review also provides a novel insight into the clinical treatment of RA.Materials and MethodsAccording to the PRISMA guidelines, databases like Web of Science, Google‐Scholar, Pubmed and Scopus were systematically searched for articles from January 1, 2018 to January 1, 2022 using The following 2 keywords: "rheumatoid arthritis", "Inflammatory cytokines", "ILs", "serum amyloid protein A", "matrix metalloproteinase 3", "RANKL", "Glucose‐6‐phosphoisomerase", "Anti‐keratin antibody", "1,25‐Dihydroxyvitamin D3".ResultsIndicators like MMPs, ILs, glucose‐6‐phosphate isomerase (GPI), anti‐keratin antibody (AKA) and receptor activator of nuclear factor‐κB ligand (RANKL) are the current hotspots in the efficacy research of RA. The present review suggests that ILs are highly expressed in the serum and synovial tissues of RA patients. By targeted inhibition of ILs with inhibitor application, precise RA treatment can be achieved.ConclusionsBased on these results, it can be concluded that inflammatory factors have certain guiding significance in the diagnosis and efficacy evaluation of RA. However, the mechanisms of interactions among them are rather complex, which deserve further exploration.

A beneficial role of GLP-1 receptor agonist therapy in ABCC8-MODY (MODY 12)

Maturity-onset diabetes of the young (MODY) is an inherited form of diabetes resulting from a mutation in a single gene. ABCC8-MODY is caused by mutations in the ABCC8 gene, which encodes sulfonylurea receptor 1 (SUR1), a regulatory component of the ATP-sensitive potassium (K_ATP) channel found in beta cells. In ABCC8-MODY, mutations in the ABCC8 gene interfere with insulin secretion in response to glucose. Recent evidence suggests that therapy with GLP-1 receptor agonists (GLP-1 RAs) may be beneficial in ABCC8-MODY. This report presents a successful treatment of a 49-year-old woman diagnosed with ABCC8-MODY using the GLP-1 RA semaglutide. The patient, who had been previously receiving insulin therapy, experienced significant improvements in glycemic control and weight loss after transitioning to semaglutide. GLP-1 RAs potentially enhance insulin secretion in ABCC8-MODY by activating multiple signaling pathways involved in insulin secretion. The report highlights the potential of GLP-1 RA therapy as an alternative to sulfonylureas and insulin for individuals with ABCC8-MODY. GLP-1 RAs have previously demonstrated benefits in other forms of MODY. Understanding the molecular mechanisms through which GLP-1 RAs promote insulin secretion, including their effects on KATP channels and activation of PKA and Epac signaling, offers valuable insights into their therapeutic effects.
