The global prevalence of obesity and type 2 diabetes mellitus (T2DM)—the most common metabolic disorders—has reached epidemic proportions over the past half-century, with obesity being a key driver of insulin resistance and T2DM development. These disorders are characterized by metaflammation (chronic low-grade inflammation across multiple metabolic organs like adipose tissue, liver, muscle, and the gut), which disrupts metabolic homeostasis, exacerbates insulin resistance, impairs insulin secretion, and links to other comorbidities such as cardiovascular diseases. A major advance in understanding inflammation resolution is the identification of specialized pro-resolving mediators (SPMs), a family of lipid mediators including resolvins, lipoxins, protectins, and maresins. Derived from polyunsaturated fatty acids (e.g., EPA, DHA), SPMs actively regulate inflammation resolution by constraining pro-inflammatory cell infiltration (e.g., neutrophils), promoting anti-inflammatory macrophage polarization (M2), enhancing efferocytosis (clearance of apoptotic cells), and preserving tissue barrier integrity—without inducing immunosuppression. This review summarizes evidence from human and animal studies on obesity-related metaflammation in metabolic tissues and the role of SPMs in resolving this inflammation. It details SPM mechanisms (e.g., maintaining adipose tissue homeostasis, improving insulin sensitivity, alleviating hepatic steatosis) and highlights their dysregulation in obesity (e.g., impaired biosynthesis, reduced receptor expression) as a critical driver of metabolic dysfunction. Finally, the review discusses the therapeutic potential of SPM-targeted strategies (e.g., ω-3 PUFA supplementation, SPM receptor activation) for alleviating obesity, T2DM, metabolic dysfunction-associated steatotic liver disease (MAFLD), and other metabolic disorders, along with future research directions in this field.

Glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1RAs) and dual incretin agonists have demonstrated significant potential in improving adipose tissue function beyond their established effects on appetite suppression and weight loss. These agents not only reduce overall fat mass but also induce favorable changes in fat distribution and adipose tissue quality. Notably, they enhance brown adipose tissue (BAT) activity and promote the browning of white adipose tissue (WAT), thereby increasing energy expenditure. They are associated with reductions in adipocyte size, particularly within visceral fat depots, alongside improvements in metabolic health markers. The aim of this publication is to provide a literature review on the effects of GLP-1RAs and dual incretin agonists on adipocyte type and size, adipose tissue functional remodeling, and their implications for obesity management. These findings highlight the capacity of incretin-based therapies to modulate adipose tissue biology, offering metabolic benefits that extend beyond weight reduction.

Aim: Metabolic syndrome (MetS) is associated with chronic conditions, including type 2 diabetes mellitus (T2DM) and cardiovascular disorders. New markers are needed for the early detection and successful treatment of MetS, especially in patients with T2DM. The serum uric acid-to-creatinine ratio (UCR) and waist-to-height ratio (WHR) are novel markers in various chronic metabolic disorders. We aimed to compare WHR, UCR, and other metabolic and laboratory markers in T2DM patients with and without MetS. Methods: Patients with T2DM who visited the outpatient clinics of our institution were enrolled in the study. Total diabetic subjects were 239 of which 180 were in MetS group while 59 were in without MetS group. Data from both study groups were compared. Results: The serum UCR in the MetS and control groups was 6.3 ± 2.1 and 5.8 ± 1.6, respectively (p = 0.04). The WHR in the MetS and control groups was 0.65 (0.47–0.87) and 0.62 (0.35–0.84), respectively (p < 0.001). Significant positive correlations were observed between UCR and triglycerides (r = 0.17, p = 0.009), waist circumference (r = 0.13, p = 0.046), hip circumference (r = 0.18, p = 0.006), BMI (r = 0.2, p = 0.002), and GFR (r = 0.4, p < 0.001). Similarly, significant positive correlations were noted between WHR and systolic blood pressure (r = 0.12, p = 0.049), weight (r = 0.5, p < 0.001), BMI (r = 0.7, p < 0.001), and UCR (r = 0.12, p = 0.047). In the ROC analysis, the sensitivity and specificity of WHR (when higher than 0.64) in detecting MetS were 72% and 54%, respectively (AUC: 0.69, p < 0.001, 95% CI: 0.61–0.77). Conclusions: We propose that WHR and UCR could be valuable tools for the early detection of MetS in patients with T2DM. The ease and low cost of evaluating WHR and UCR make them practical markers for monitoring and diagnosing MetS.
