Chronic systemic vascular inflammation is a chronic autoimmune disease with a varied course and a multisystemic nature. It most commonly affects young and middle-aged women, and its symptoms can be both mild and life-threatening. An ambiguous clinical presentation often results in delayed diagnosis, which makes early treatment difficult. A holistic approach to treatment is crucial, encompassing not only pharmacological methods but also an appropriate diet and lifestyle that supports the immune system.
Systemic lupus erythematosus pathogenesis: From immunological tolerance breakdown to multi-organ autoimmune sequelae
Systemic lupus erythematosus (SLE) represents a complex, chronic autoimmune disorder characterized by the immune system’s aberrant recognition of self-antigens, leading to sustained inflammatory damage across multiple organ systems. The cornerstone of its pathogenesis lies in the breakdown of immunological tolerance—a physiological safeguard that normally prevents self-reactive immune responses. This dysfunction triggers the uncontrolled production of autoantibodies, predominantly targeting nuclear constituents such as double-stranded DNA, histones, and ribonucleoproteins, which subsequently form circulating immune complexes. The deposition of these complexes in diverse tissues—including the renal glomeruli (resulting in glomerulonephritis), cutaneous layers (manifesting as malar rash), synovial membranes (inducing arthritis), and neural structures (provoking neuropsychiatric lupus syndromes)—elicits a chronic immuno-inflammatory state. The clinical course of SLE is marked by episodic flares interspersed with periods of remission. Its etiopathogenesis arises from a multifactorial interplay of genetic susceptibilities (e.g., HLA-DR gene polymorphisms, complement deficiencies such as C1q or C4 deficits), environmental exposures (ultraviolet radiation as a well-documented trigger, viral infections, industrial toxins, and tobacco smoke), hormonal imbalances (particularly the immunomodulatory effects of estrogens), and epigenetic alterations (including DNA methylation and histone modification patterns). The striking female predominance during reproductive years (with a 9:1 female-to-male ratio) underscores the pivotal role of hormonal factors not only in disease initiation but also in the perpetuation of autoimmune responses, as substantiated by recent research, including the 2022 study by Ameer and colleagues.
