Bidirectional Mendelian randomized analysis of circulating inflammatory factor levels and radiation-related skin and subcu-taneous tissue diseases
Objective To investigate the causal relationship between levels of circulating inflammatory factor levels and radiation-re-lated skin and subcutaneous tissue diseases(RRDST).Methods Based on Genome Wide Association Study data,five Mendelian ran-domization(MR)methods were used to analyze the relationship between serum levels of 70 circulating inflammatory factors and RRDST.Results Positive MR results showed that CC chemokine ligand 11(CCL11)(odds ratio=0.941 8,95%confidence interval 0.891 0-0.995 5,P=0.034 1),chemokines(CXCL)10(odds ratio=0.929 5,95%confidence interval 0.881 9-0.979 7,P=0.006 5),os-toeprotegerin(OPG)(odds ratio=0.868 3,95%confidence interval 0.774 9-0.973 0,P=0.015 0)were significantly negatively cor-related with RRDST,CXCL6(odds ratio=1.108 2,95%confidence interval 1.036 1-1.185 3,P=0.002 8),interleukin(IL)-15 re-ceptor α(odds ratio=1.080 0,95%confidence interval 1.022 8-1.140 4,P=0.005 5),leukemia inhibitory factor receptor(LIFR)(odds ratio=1.073 4,95%confidence interval 1.014 6-1.135 7,P=0.013 8),monocyte chemoattractant protein-1(MCP-1)(odds ratio=1.092 8,95%confidence interval 1.035 0-1.153 8,P=0.001 4),sulfotransferase(SULT)1A1(odds ratio=1.066 5,95%confidence interval 1.005 4-1.131 3,P=0.032 4)were positively correlated with RRDST.Sensitivity analysis confirmed the robust-ness of these causal relationships.Reverse MR analysis did not find a significant reverse causal relationship between RRDST and circu-lating inflammatory factor levels.Conclusion Forward and reverse MR analysis revealed a significant causal relationship between the levels of specific inflammatory factors and the risk of RRDST.CCL11,CXCL10 and OPG levels are significantly negatively correlated with the risk of RRDST.The levels of CXCL6,IL-15 receptor α,LIFR,MCP-1 and SULT1A1 are significantly positively correlated with the risk of RRDST.These findings provide new insights into understanding the pathological mechanisms of RRDST and provide poten-tial targets for future clinical and public health interventions.
