Background: This study evaluated the association between peptidyl arginine deiminase type IV (PADI4) and interleukin 33 (IL-33) with systemic lupus erythematosus (SLE) and juvenile idiopathic arthritis (JIA). Method: We searched the PubMed, Web of Science, Embase and Cochrane Library databases to retrieve articles published up to January 20, 2023. Stata/SE 17.0 (College Station, TX) software was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). The cohort study, case-control study focusing on the PADI4, IL-33 polymorphism, and SLE, JIA were retrieved. The data included basic information of each study and the genotypes and allele frequencies. Results: Studies in PADI4 rs2240340 = 2 and 3 IL-33(rs1891385 = 3, rs10975498 = 2, rs1929992 = 4) were found in 6 articles. Overall, only the IL-33 rs1891385 show significant association between SLE in all 5 models. The results were OR (95% CI) = 1.528 (1.312, 1.778), P =.000 in Allele model (C vs A), OR (95% CI) =1.473 (1.092, 1.988), P =.000 in Dominant model (CC + CA vs AA), 2.302 (1.583, 3.349), P =.000 in Recessive model (CC vs CA + AA), 2.711 (1.845, 3.983), P =.000 in Homozygote model (CC vs AA), 5.568 (3.943, 7.863), P =.000 in Heterozygote model (CA vs AA). PADI4 rs2240340, IL-33 rs10975498, IL-33 rs1929992 were not found to be association with the risk of SLE and JIA. In gene model, statistically significant association was found between IL-33 rs1891385 and SLE in sensitivity analysis. Egger's publication bias plot showed there was no publication bias (P =.165). Only in recessive model the heterogeneity test was significant (I2= 57.9%, P ≤.093) of IL-33 rs1891385. Conclusion: The current study suggests that in all 5 model, IL-33 rs1891385 polymorphism may be associated with genetic susceptibility to SLE. There was unclear association found between PADI4 rs2240340, IL-33 rs10975498, and IL-33 rs1929992 polymorphisms and SLE and JIA. Due to the limitations of included studies and the risk of heterogeneity, additional research is required to confirm our findings. PROSPERO registration number: CRD42023391268.
