Objective: To investigate the correlation between serum ferritin (SF) level and liver damage in the acute stage of dengue fever. Methods: A retrospective study was conducted to analyze 171 cases diagnosed with dengue fever as dengue fever group and 130 healthy patients as control group in Hangzhou 3A grade hospital from July to December 2017. Clinical data, SF and liver function related indicators were collected from both groups: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) to analyze the correlation between liver damage and SF in patients with dengue fever. Results: ALT, AST, and SF levels were significantly higher in the dengue fever group than those in the healthy control group (Z = 11.553, 15.054 and 15.163, P < 0.001). SF levels were higher in the dengue fever combined with liver damage group than those without the liver damage group (z = 6.930, P < 0.001). However, there was no statistically significant differences in age, gender, peak body temperature, and history of liver disease (P > 0.05). In addition, Spearman's correlation analysis showed that SF was positively correlated with ALT, AST, and TBIL (r = 0.464, 0.531 and 0.315, P < 0.001). Among dengue patients with different SF levels, there were significant difference in ALT, AST levels and incidence of liver damage (H = 14.240 and 17.584, χ(2) = 49.547, P < 0.001). Patients with higher SF levels had higher ALT, AST levels and incidence of liver damage. Binary logistic regression analysis showed that hyperferritinemia (SF≥500 ng/ml) was the risk factor for dengue fever combined with liver damage (OR = 8.120, P < 0.001). Furthermore, ROC curve analysis showed that the AUC for SF to judge dengue fever combined liver damage was 0.846 (95% CI: 0.785-0.908), and the sensitivity and specificity when the SF cut-off value was 1 506 ng/ml were 74.8% and 83.3%. Conclusion: There is a certain correlation between the SF level and the degree of liver damage in acute stage of dengue fever patients, and hyperferritinemia is a risk factor for dengue fever combined with liver damage.
目的： 探讨登革热急性发热期血清铁蛋白（SF）水平与肝脏损害的相关性。 方法： 回顾性研究分析2017年7月至2017年12月于杭州三甲医院确诊为登革热的171例患者为登革热组和130例健康体检者为对照组。收集两组人群临床资料和SF、肝功能相关指标数据：丙氨酸转氨酶（ALT）、天冬氨酸转氨酶（AST）、总胆红素（TBil）等，分析登革热患者肝损害情况及与SF的相关性。 结果： 登革热组患者ALT、AST、SF水平均显著高于健康对照组（Z = 11.553、15.054和15.163，P值均< 0.001）；且登革热合并肝损伤组患者SF水平较无肝损伤组患者升高明显（Z = 6.930，P < 0.001），而年龄、性别、体温峰值、肝病史均差异无统计学意义（P > 0.05）；此外，Spearman相关分析显示，SF与ALT、AST、TBil均呈正相关(r = 0.464、0.531和0.315，P值均< 0.001)；且不同SF水平的登革热患者其ALT、AST水平（H分另为14.240、17.584，P值均< 0.001）和肝损伤发生率（χ(2) = 49.547，P < 0.001）比较，差异均有统计学意义，更高SF水平的患者其ALT、AST水平以及肝损伤发生率均升高；二分类logistic多元回归提示高铁蛋白血症（SF≥500 ng/ml）是登革热合并肝损伤的危险因素（OR = 8.120，P < 0.001）；ROC曲线分析示，SF判断登革热合并肝损伤的曲线下面积为0.846（95%可信区间：0.785～0.908），取SF截断值为1 506 ng/ml时，敏感度74.8%，特异度83.3%。 结论： 登革热患者发热期SF水平与肝脏损害程度具有一定相关性，且高铁蛋白血症是登革热合并肝脏损害的危险因素。.
