Acute necrotizing retinal vasculitis as onset of systemic lupus erythematosus: A case report.

Rationale: Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by autoantibody production, complement activation, and deposition of immune complexes in tissues and organs. SLE can involve any region of the visual system. Although ocular manifestations are not part of the classification criteria for SLE, they can be observed in up to one-third of the patients with SLE.

[The influence of pregnancy on the systemic lupus erythematosus].

Systemic lupus erythematosus (SLE) is an autoimmune disease caused by the interaction between genetic and environment factors which leads to abnormal immune responses. SLE affects more commonly women of childbearing age which raises the following questions--the influence of the disease activity on pregnancy and the influence of pregnancy on disease activity. On the one hand physiological changes occurring during pregnancy could lead to increased SLE activity, on the other hand the latter could mimic SLE activity.

Role of the promoter polymorphism IL-6 -174G/C in dermatomyositis and systemic lupus erythematosus.

The promoter polymorphism -174G/C within the interleukin-6 gene (IL-6) has been reported to have a functional importance through the modulation of IL-6 gene expression in vitro and in vivo. IL-6 is thought to play an important role in autoimmune diseases and the effect of its receptor inhibitor-tocilizumab-has been recently studied. The aim of this case-control study was to investigate the association between the interleukin-6 -174G/C single nucleotide polymorphism and the susceptibility to dermatomyositis (DM) and systemic lupus erythematosus (SLE) in Bulgarian patients.

Classification criteria for neuropsychiatric systemic lupus erythematosus: do they need a discussion?

Background: At the current stage, the criteria for making the diagnosis of SLE (ARA, 1982) include only two neuropsychiatric manifestations: seizures and psychoses. In view of the need for early detection of the lesions of the nervous system, we set ourselves to the task of developing an approach for making the diagnosis of NPSLE (neuropsychiatric SLE) on the basis of criteria with high sensitivity and specificity.

Methods: In view of determining the type and incidence of the lesions of the nervous system (NS), clinical, laboratory, and instrumental examinations were performed within the period from 1998 to 2006 in 225 patients with SLE.
