Obesity is increasingly recognized not only as a metabolic disorder, but also as a state of chronic low-grade inflammation that predisposes to systemic complications. Within this context, Dercum’s disease (DD), or adiposis dolorosa, emerges as a rare yet debilitating disorder characterized by painful subcutaneous lipomas, most commonly affecting middle-aged women. Despite its clinical impact, DD remains underdiagnosed and is often misclassified as lipedema, fibromyalgia, or lipomatosis, complicating prevalence estimates and hindering the development of targeted interventions. Current evidence suggests that DD represents a distinctive model of inflammatory obesity, where adipose tissue actively contributes to pain generation rather than serving as a passive fat reservoir. Histological and molecular findings point to adipose tissue dysfunction, immune cell infiltration, and elevated secretion of pro-inflammatory adipokines, signals which appear to fuel systemic low-grade inflammation, perineural immune interactions, and nociceptor sensitization. Peripheral mechanisms further shape the clinical phenotype. While familial clustering suggests possible genetic contributions, no definitive markers have been identified, and the role of obesity-induced epigenetic modifications remains unexplored. Therapeutic strategies remain largely symptomatic, including analgesics, antidepressants, physical rehabilitation, and surgical excision of lipomas, whereas molecularly targeted and diet-based interventions are still experimental. This article discusses the pathophysiology of DD, current treatments, and future perspectives, emphasizing that advancing patient registries, omics-based analyses, and interdisciplinary clinical trials will be crucial to elucidate disease mechanisms and guide novel therapies. Improved understanding of DD may not only enhance patient care, but also provide broader insights into the interplay between obesity, inflammation, and chronic pain.

The present review explores the role of endogenous hormones, such as cortisol, melatonin, thyroid hormones, sex hormones, and insulin, in the modulation of the immune response to a human metapneumovirus (hMPV) infection. hMPV is a respiratory pathogen responsible for severe infections, particularly in vulnerable populations like children and the elderly. The virus triggers inflammatory responses through various molecular processes, including cytokine production and immune signaling pathways. Notably, these processes can be influenced by endocrine factors, such as hormones. Cortisol, through hypothalamic-pituitary-adrenal (HPA) axis activation, modulates inflammation but may contribute to immunosuppression. Melatonin inhibits the NLRP3 inflammasome, reducing lung inflammation. Thyroid hormones regulate immune responses via nuclear factor kappa B (NF-κB) and JAK/STAT pathways, while hypothyroidism may alter infection severity. Sex hormones, particularly estrogens, enhance antiviral immunity, whereas androgens may have variable effects on immune modulation. Insulin influences inflammation through NF-κB suppression, with insulin resistance potentially worsening viral pathogenesis. Therapeutic implications suggest that modulating these hormonal pathways could aid in hMPV management. Strategies such as hormone therapy, glucocorticoid regulation, and nanoparticle-based drug delivery are potential routes of intervention. The aim of the present review is to understand the complex interplay between endogenous hormones and the immune system during an hMPV infection by describing the complex molecular mechanisms associated with these processes.

Effect of diet on the microbiota and immune system in patients with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by widespread inflammation and organ damage. Studies indicate that diet significantly influences the gut microbiota, which, in turn, affects the immune system. This article explores gut microbiota dysbiosis in SLE patients and potential mechanisms related to dietary interventions and immune function. It highlights specific dietary patterns, such as a high-fibre diet and the Mediterranean diet, that may modulate the diversity and activity of the gut microbiota. The interaction between altered microbiota and immune responses, including the regulation of inflammatory cytokines, intestinal barrier permeability, and autoantibody production is examined. This review highlights the importance of personalized dietary strategies to modulate the diversity and activity of the gut microbiota by enhancing the immune response and potentially mitigating disease progression.
