Objective:To identify the clinical characteristics and adverse events of patients with giant cell arteritis (GCA).Methods:Patients who were hospitalized and diagnosed with GCA in Zhongshan Hospital, Fudan University, from December 2009 to November 2020 were enrolled into a retrospective study analysis. Baseline data and follow-up data were collected. Adverse events were defined as one of the following events: relapses, ischemic complications and death. Patients with adverse events were analyzed in clinical features and risk factors by univariate and multivariate analysis. Associations with adverse events were assessed using ROC curve and survival curves.Results:A total of 69 patients with GCA were included in this study, with the male: female ratio of 1∶1.03. Fatigue and headache were common symptoms. Finally, 61 patients were followed up at the end of May in 2021. Over the mean follow-up time of (35±20) months, adverse events occurred in 16 cases (26.2%). Patients with adverse events had significantly lower levels of platelet and globulin at baseline than those without adverse events [(325±142)×10 9/L vs (238±112)×10 9/L, t=2.22, P=0.030]; [(31±6) g/L vs (26±6) g/L, t=2.74, P=0.008]. Red cell volume distribution width-coefficient of variation (RDW-CV) was considered an independent risk factor for adverse events [ OR (95% CI)=0.32 (0.14,0.74), P=0.008]. Further, patients especially with RDW-CV<14.75% were prone to have adverse events, which occurred in 2.6%, 20.5%, 25.6%, 33.3%, 41.00% in 1, 2, 3, 5, 10 years. Its risk increased significantly after 2 years ( P=0.042, P=0.021, P=0.002, P=0.001). The incidence of adverse events was much higher in patients with RDW-CV<14.75%(95% CI=0.002). Conclusion:Adverse events are common in patients with GCA. RDW-CV is an independent risk factor for having adverse events. Low level of RDW-CV predicts an increased risk of adverse events by the following years.
