title: The association of anti-annexin1 antibodies with the occurrence of skin lesions in systemic lupus erythematosus.
abstract: Anti-annexin1 antibodies are associated with the subtypes of cutaneous lupus and are elevated in systemic lupus erythematosus (SLE) patients. In this study, we investigated the correlation of this antibody with the incidence of SLE skin lesions. The presence of anti-annexin1-IgG and-IgM determined by Western blot was no different among healthy controls and SLE patients with and without skin lesions. Serum levels of anti-annexin1-IgG and -IgM measured by enzyme-linked immunosorbent assay were comparable between patients with and without skin lesions, whereas anti-annexin1-IgM was lower in SLE patients than in healthy controls. Annexin1 was abundantly detected in each epidermal layer in lupus lesional skin. Additionally, anti-annexin1-IgG was higher in SLE patients with arthritis and negatively correlated with white blood cells (WBC). Anti-annexin1-IgM was higher in patients with antinuclear antibody (ANA)-positive sera, and was positively related to hemoglobin and total serum IgM. Collectively, anti-annexin1 antibodies are not related to the incidence of skin lesions in SLE, and annexin1 abundantly distributes in epidermis in lesional skin.
