Abstract:
Objective:To explore the clinical immune manifestations and high risk factors of children with neuropsychiatric systemic lupus erythematosus (NPSLE), so as to find the basis for early clinical differential diagnosis, prevention and treatment of NPSLE.Methods:Ninety-four children with systemic lupus erythematosus (SLE) admitted to Hunan Children′s Hospital from January 1, 2015 to April 30, 2022 were retrospectively selected. Among them, 19 children with NPSLE were in the NPSLE group, and 75 children without NPSLE were in the SLE group. The disease activity, immune system, lymphocyte subsets, inflammatory factors and autoantibodies were compared between the two groups.Results:Among 94 children with SLE, the incidence of NPSLE was 20.21%(19/94). The most common symptoms of 19 children with NPSLE were headache, epileptic seizure and cerebrovascular disease. The Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2000 score was (19.89±8.33)points. Most of them had a good prognosis through hormone intervention. Compared with the SLE group, NPSLE group had higher SLEDAI-2000 score, white blood cell count, urine protein, erythrocyte sedimentation rate (ESR), interferon (IFN)-α, positive rate of anti-Sm antibody and anticardiolipin antibody, lower platelet count, interleukin-2 (IL-2), C 3, C 4 level (all P<0.05), while there was no significant difference in positive rate of anti-dsDNA antibody and anti-SSA antibody between the two group (both P>0.05). Conclusions:Compared with SLE children, children with NPSLE are often complicated with many kinds of abnormal immune function, mainly abnormal humoral immune function and many kinds of positive antibody, with increased inflammatory factors.
