Background & Aims: Type 2 diabetes mellitus (T2DM) poses a significant global health challenge due to various lifestyle factors contributing to its prevalence and associated complications. Chronic low-grade inflammation, characterized by elevated levels of inflammatory markers such as C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α), plays a pivotal role in the pathogenesis of T2DM. Modulation of the gut microbiota through microbiome-targeted therapy (MTT), including probiotics, prebiotics, and synbiotics, has emerged as a potential strategy to mitigate inflammation and improve metabolic outcomes in T2DM.
Methods: A systematic review and meta-analysis were conducted following PRISMA guidelines to evaluate the impact of MTT on inflammatory markers in patients with T2DM. Searches were performed in PubMed, Scopus, and Web of Science databases up to June 2024, with inclusion criteria limited to English-language meta-analyses of randomized controlled trials (RCTs) assessing the effects of probiotics, prebiotics, or synbiotics on inflammatory markers in T2DM patients.
Results: Ten meta-analyses met the inclusion criteria, comprising studies investigating the effects of various MTT interventions on CRP, IL-6, and TNF-α levels in T2DM patients. Meta-analysis results indicated significant reductions in CRP (SMD: -0.070; 95 % CI: -0.119 to -0.020) and TNF-α (SMD: -0.370; 95 % CI: -0.554 to -0.186) levels following MTT, while IL-6 reductions (SMD: -0.070; 95 % CI: -0.269 to 0.129) did not reach statistical significance. However, heterogeneity in study quality, intervention protocols, and participant demographics posed challenges in interpretation.
Conclusions: While improvements in inflammatory markers with MTT have been observed, significant limitations-such as heterogeneity in study quality and variation in intervention protocols-highlight the need for further research to confirm its efficacy and clarify underlying mechanisms. Future studies should aim to address these limitations by exploring variations in dosage, supplement formulations, and bacterial strains, which are crucial for improving the reliability and broader applicability of MTT in the management of T2DM.

Does Lifelong Exercise Counteract Low-Grade Inflammation Associated with Aging? A Systematic Review and Meta-Analysis.
Sports Med
January 2025
Medical Services, Real Madrid, Madrid, Spain.
Background: Aging is associated with sustained low-grade inflammation, which has been linked to age-related diseases and mortality. Long-term exercise programs have been shown to be effective to for attenuating this process; however, subsequent detraining might negate some of these benefits. Master athletes, as a model of lifelong consistent exercise practice, have been suggested to present similar inflammatory profiles to untrained young adults.

Background: Atopic dermatitis (AD) is a chronic, pruritic, and inflammatory dermatosis seen in individuals with an atopic predisposition. This study aimed to examine the immunoreactivity of spexin and TRPM2 in skin samples from patients with AD and MF lesions using immunohistochemical methods.
Materials And Methods: The study utilized a total of 60 skin samples, comprising 20 from AD patients, 20 from MF patients, and 20 from control subjects.
Brief Report: Genital Microbiome, Inflammation, and Tenofovir Levels in Transgender Men and Cisgender Women Taking Oral PrEP.
J Acquir Immune Defic Syndr

Division of Infectious Diseases and Global Public Health, University of California San Diego, San Diego, CA.
Background: Little is known about the efficacy of preexposure prophylaxis (PrEP) or what biologic factors may influence HIV transmission in transgender men (TGM). In this study, we sought to explore the effect of testosterone on the vaginal microbiome, cervicovaginal fluid (CVF) tenofovir concentrations, and levels of CVF inflammatory markers in TGM on PrEP.
Methods: Cervicovaginal fluid was collected from 13 TGM (7 using testosterone) and 32 cisgender women (CGW) on PrEP.

Type 1 diabetes mellitus (T1DM), known as insulin-dependent diabetes mellitus, is characterized by persistent hyperglycemia resulting from damage to the pancreatic β cells and an absolute deficiency of insulin, leading to multi-organ involvement and a poor prognosis. The progression of T1DM is significantly influenced by oxidative stress and apoptosis. The natural compound eugenol (EUG) possesses anti-inflammatory, anti-oxidant, and anti-apoptotic properties.
