AI Article Synopsis

  • Frailty is characterized by reduced functional reserve, leading to higher morbidity and mortality, and this study investigates the link between IL10 gene polymorphisms and frailty in a Mexican population.
  • The research analyzed 984 participants, categorizing them into nonfrail, prefrail, and frail groups, revealing associations between specific IL10 polymorphisms (rs1800896, rs1800871) and increased frailty susceptibility.
  • Two risk haplotypes (ACG and CCG) and three protective haplotypes (ACA, ATG, and ATA) were identified, indicating that certain genetic variations in IL10 may influence frailty risk in older adults.

Article Abstract

Frailty is a geriatric syndrome, characterized by a loss in functional reserve with an increase in morbidity and mortality. There are no reports that link the genetic polymorphisms between interleukin 10 (IL10) and frailty; for this reason, our objective was used to analyze the role of the polymorphisms of IL10 (rs1800896, rs1800871) in the susceptibility to frailty in a Mexican population. Our study included 984 participants divided into 368 nonfrail, 309 prefrail, and 307 frail. The models for the polymorphisms rs1800896 and rs1800871 were recessive models in association with frailty (OR = 2.3, CI 95% = 1.6-3.2; OR = 1.53, CI 95% = 1.0-2.6), respectively. Two risk haplotypes were identified: ACG and CCG (p < .0001), and three protective haplotypes were identified: ACA, ATG, and ATA (p < .05). This study evaluated the relationship between IL10 and the three subtypes of this geriatric syndrome (frail, prefrail, and nonfrail). These results support a greater susceptibility to frailty for the minor alleles of rs1800871 and rs1800896. In addition, we found two risk haplotypes supporting the participation of the IL10 in the susceptibility for frailty in the Mexican population.

Obesity is a complex health risk influenced by genetic, environmental, and lifestyle factors. This review systematically assessed the association between interleukin gene polymorphisms (rs16944, rs17561, rs1143623, rs1143633, rs1143634, rs1800587, rs2234677, and rs4848306), (rs180275, rs1805010, rs13306435, rs1800795, rs1800796, rs1800797, rs2228145, rs2228145, rs2229238, and rs4845623), (rs1518110, rs1518111, rs1800871, rs1800872, rs1800896, rs1878672, rs2834167, rs3024491, rs3024496, rs3024498, and rs3024505), (rs3136617, rs3136618, and rs2296135), and (rs187238, rs1946518, rs2272127, rs2293225, and rs7559479) and the risk of overweight and obesity in adults, focusing on rs1800795 through a meta-analysis. The focus on in this review arises from its pleiotropic nature and unclear effect on obesity risk.

Article Synopsis
  • Infections from the dengue virus, Orthoflavivirus denguei, can show no symptoms or a range of clinical signs due to its complex interactions with viral and host factors.
  • The study examined specific genetic variations (SNPs) in the interleukin-10 (IL-10) gene among 333 individuals in northeastern Brazil to see how they relate to symptomatic dengue.
  • Findings revealed that certain genotypes and the G allele of the -1082 A/G SNP are associated with a higher risk of developing symptomatic dengue, particularly in contrast to those with asymptomatic infections.

Department of Rheumatology, Korea University Anam Hospital, Korea University College of Medicine, Seoul, South Korea.

This study sought to investigate the association between interleukin-10 (IL10) polymorphisms and susceptibility to Sjögren's syndrome. A systematic search of the Medline, Embase and Web of Science databases was conducted to identify relevant articles from inception to April 2024. No restrictions were placed on race, ethnicity or geographic area, but only studies published in English were included.

Interleukin-10 (IL-10) is an anti-inflammatory cytokine whose levels are elevated in patients with severe COVID-19. IL-10 polymorphisms may play a role in increasing IL-10 levels and the severity of COVID-19. This study aimed to investigate the relationship between IL-10 single nucleotide polymorphisms (SNPs) (rs1800896 [-1082 C < T], rs1800871 [-819 A > G], and rs1800872 [-592 T > G]) and the severity of COVID-19 in patients from Kermanshah Province, Iran.

Purpose: A wide range of cytokines has been demonstrated to be involved in the etiology of type 1 diabetes mellitus (T1DM). Gene polymorphisms may potentially contribute to a hereditary predisposition toward circulating cytokine levels as (high, intermediate, or low) since they can affect cytokine production or function. The aim of this study was to investigate the roles of cytokine levels and the association of single-nucleotide polymorphisms (SNPs) within cytokine genes with T1DM in Saudi children.
