Role of lymphocytes CD4/CD8 ratio and immunoglobulin G cytomegalovirus as potential markers for systemic lupus erythematosus patients with periodontal disease

Objectives The aim of the study was to analyze the correlation between periodontitis severity in systemic lupus erythematosus (SLE) with CD4/CD8 lymphocytes ratio and cytomegalovirus gamma immunoglobulin (IgG CMV) level. Materials and Methods This is a descriptive study using a cross-sectional approach that included 93 subjects who were diagnosed with SLE in Rheumatology Department, Saiful Anwar Hospital, during 2017 to 2019. Periodontitis severity was assessed by periodontal Index (PI). CD4/CD8 lymphocyte ratio was determined using flow cytometry and IgG CMV levels using enzyme-linked immunosorbent assay. Statistical Analysis The differences among the three groups were analyzed using analysis of variance. Correlation among the groups was calculated using Spearman/Pearson correlation coefficient test, while regression analysis was done using Statistical Package for the Social Sciences. Results The mean of periodontitis severity and standard deviation in SLE was 2.66 ± 1.02. There were negative correlation between CD4/CD8 lymphocyte ratio with periodontal index (r = -0.971) and positive correlation between IgG CMV level with periodontal index (r = 0.977). Conclusions Inverted CD4/CD8 ratio and IgG CMV were found associated with periodontitis severity in SLE patient. Further research was recomended that CD4/CD8 lymphocytes ratio and IgG CMV can be used as a potensial marker of periodontitis severity in SLE patients.
