PG - 5096741 LID - 10.1155/2017/5096741 [doi] LID - 5096741 AB - Background. Systemic lupus erythematosus (SLE) is an autoimmune disease with great heterogeneity in pathogenesis and clinical symptoms. Rheumatoid factor (RF) is one key indicator for rheumatoid arthritis (RA) while immunoglobulin E (IgE) is associated with type I hypersensitivity. To better categorize SLE subtypes, we determined the dominant cytokines based on familial SLE patients. Methods. RF, IgE, and multiple cytokines (i.e., IL-1beta, IL-6, IL-8, IL-10, IL-17, IFN-gamma, IP-10, MCP-1, and MIP-1beta) were measured in sera of familial SLE patients (n = 3), noninherited SLE patients (n = 108), and healthy controls (n = 80). Results. Three familial SLE patients and 5 noninherited SLE cases are with features of RF+IgE+. These RF+IgE+ SLE patients expressed significantly higher levels of IL-1beta and IL-6 than the other SLE patients (P < 0.05). IL-6 correlated with both IgE and IL-1beta levels in RF+IgE+ SLE patients (r(2) = 0.583, P = 0.027; r(2) = 0.847, P = 0.001), and IgE also correlated with IL-1beta (r(2) = 0.567, P = 0.031). Conclusion. Both IL-1beta and IL-6 are highly expressed cytokines in RF+IgE+ SLE subtype which may be related to the pathogenesis of this special SLE subtype and provide accurate treatment strategy by neutralizing IL-1beta and IL-6.
