Value of precision nutrition in the inflammatory control of systemic lupus erythematosus

Abstract

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by the production of autoantibodies directed against endogenous antigens causing various clinical manifestations, chronic inflammation and tissue damage. Although the pathophysiology of SLE remains unknown, it is recognized that genetic, epigenetic, environmental and neuroendocrine factors are involved in the development of the disease and its complications. A notable proportion of patients with SLE also present obesity, and this dysmetabolic profile can cause renal, musculoskeletal and/or respiratory deterioration, fatigue, various pathophysiological alterations and functional deterioration. In this context, precision nutrition emerges as a promising tool in the inflammatory control of SLE, especially in patients with associated obesity. Various studies demonstrate the beneficial influence of balanced dietary patterns in macronutrients with foods rich in fiber, vitamins, minerals, antioxidants and polyphenols on the inflammatory control of SLE and the most diverse pathologies, highlighting the Mediterranean diet and plant-based diets. Finally, the intestinal microbiota may play a relevant role in this clinical scenario, since dysbiosis is associated with inflammatory processes and immune deregulation. It is believed that precision nutrition can modulate inflammatory profiles and immune dysfunctions to ensure better quality of life and metabolic well-being of SLE patients with the support of precision omics technologies.
