Association between shortened telomere length and systemic lupus erythematosus: a meta-analysis

ObjectiveWe aimed to evaluate the relationship between telomere length and systemic lupus erythematosus (SLE).MethodsPUBMED and EMBASE databases were searched; meta-analyses were performed comparing telomere length in SLE patients and healthy controls, and on SLE patients in subgroups based on ethnicity, sample type, assay method and data type.ResultsEight studies including 472 SLE patients and 365 controls were ultimately selected which showed that telomere length was significantly shorter in the SLE group than in the control group (standardized mean difference (SMD) = −0.835, 95% confidence interval (CI) = −1.291 to −0.380, p = 3.3 × 10−4). Stratification by ethnicity showed significantly shortened telomere length in the SLE group in Caucasian, Asian and mixed populations (SMD = −0.455, 95% CI = −0.763 to −0.147, p = 0.004; SMD = −0.887, 95% CI = −1.261 to −0.513, p = 3.4 × 10−4; SMD = −0.535, 95% CI = −0.923 to −0.147, p = 0.007; respectively). Furthermore, telomere length was significantly shorter in ...
