Objective:It aims to evaluate the diagnostic ability of CGRP and other blood indicators in vestibular migraine(VM)patients,and to explain the potential pathological effects of these biomarkers.The hypothesis of VM being a variant of migraine was examined.Methods:A total of 32 VM patients,35 migraine patients,and 30 healthy control subjects(HC)were selected for this cross-sectional study.Detailed statistics on demographic data,clinical manifestations,calcitonin gene-related peptide(CGRP)and common clinical laboratory indicators were measured within 24 hours from the onset of the conditions.Receptor operating characteristic(ROC)curve and area under the curve(AUC)were analyzed for biomarkers.The risk factors of VM and migraine were determined through univariate and multivariate analyses.Results:Compared with HC,serum CGRP levels(p(VM)=0.012,p(Migraine)=0.028)increased and Mg^(2+)levels(p(VM)<0.001,p(Migraine)<0.001)deceased in VM patients and migraine patients.In multiple logistic regression,VM was correlated with CGRP[odds ratio(OR)=1.07;95%confidence interval(CI),1.02-1.12;P=0.01]and Mg^(2+)[odds ratio(OR)=0.03;95%CI,0.07-0.15;P<0.001].Migraine was correlated with CGRP[odds ratio(OR)=1.07;95%CI,1.02-1.12;P=0.01]and Mg^(2+)[odd ratio(OR=0.01;95%CI,0-0.02;P<0.001)].Mg^(2+)discriminated good differentiation between VM and migraine groups,with AUC of 0.649(95%CI,0.518 to 0.780).The optimal threshold for Mg^(2+)to diagnose VM was 0.805.Conclusions:This study demonstrated that CGRP and Mg^(2+)may be promising laboratory indicators to discriminate HC from VM/migraine,while Mg^(2+)may be uded as a discriminator between VM and migraine.
