Abstract

The immune system has an important role in the development of systemic lupus erythematosus (SLE) and chronic periodontitis (CP). Altered cytokines levels characterise both diseases and contributes to periodontal tissue damage in CP and to macrocomplexes deposition with connective tissue destruction in SLE. This study aimed to evaluate the production of salivary cytokines in patients with SLE and its association with periodontal status. The sample comprised 70 SLE patients and 70 paired controls. SLE activity and damage were scored using Systemic Lupus Erythematosus Disease Activity Index 2000 and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index. Subjects were classified as without or with CP. Salivary concentrations of IL-33, MMP2/TIMP2, RANK and OPG were measured by ELISA, while IL-2, IFNγ, TNFα, IL-4, IL-6, IL-10 and IL-17A were determined by Cytometric Bead Array. Linear regression models analysed association among SLE, CP and salivary cytokines. IL-6 and IL-17A concentrations were significantly higher in SLE/CP patients than controls/CP. Concentrations of IL-6, IL-17A and IL-33 were increased in SLE/CP individuals when compared to SLE without CP. Multivariate model revealed as...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
