特高海拔地区鼻出血与同型半胱氨酸及气候要素关系分析

Analysis of the relationship between epistaxis and homocysteine and climatic factors in ultra-high altitude area

目的分析特高海拔地区鼻出血的相关影响因素,为特高海拔地区鼻出血的防治提供依据。方法收集2021年1月至2022年12月就诊于那曲市人民医院耳鼻喉科门诊鼻出血患者206例,住院鼻出血患者54例,住院非鼻出血患者69例,比较住院鼻出血患者与非鼻出血患者的既往史、饮酒史、吸烟史以及血清同型半胱氨酸、白细胞数量,红细胞数量,血细胞比容,血红蛋白,平均血红蛋白浓度,对有显著差异的因素进行二元logistic回归分析;收集那曲市2021年1月至2022年12月的月平均气温、气压、湿度、2 min风速,分析门诊、住院鼻出血患者数量与气候要素间的相关性。结果病例组患者有高血压病史例数多于对照组,差异有统计学意义(P=0.013);病例组血清同型半胱氨酸水平高于对照组(P<0.001),红细胞数量、血细胞比容、血红蛋白及平均血红蛋白浓度低于对照组,差异有统计学意义(P=0.001、0.001、0.001、0.039);高血压病史、血清同型半胱氨酸含量为鼻出血的危险因素,有高血压病史患者患鼻出血的可能性是无高血压病史患者的3.713倍(P=0.022),血清同型半胱氨酸浓度每增加1,鼻出血患病风险增加13.1%(P=0.001)。结论那曲地区鼻出血患者血清同型半胱氨酸水平升高,红细胞数量、血细胞比容、血红蛋白浓度及平均血红蛋白浓度降低。高血压病史、同型半胱氨酸为鼻出血的危险因素,有高血压病史患者患鼻出血的可能性是无高血压病史患者的3.713倍,同型半胱氨酸浓度每增加1,鼻出血患病风险增加13.1%,积极干预高血压及血清同型半胱氨酸能有效预防鼻出血的发生。

Objective To analyze the related influencing factors of epistaxis in extremely high altitude area,and to provide evidence for the prevention and treatment of epistaxis in extremely high altitude area.Methods From January 2021 to December 2022,206 outpatients with epistaxis,54 inpatients with epistaxis and 69 inpatients withoutepistaxis in theDepartment of Otorhinolarygology,Naqu People's Hospital were collected.The previous history,drinking history,smoking history,serum homocysteine(Hcy),white blood cell count(WBC),red blood cell count(RBC),hematocrit(HCT),hemoglobin(HGB)and mean hemoglobin concentration(MCHC)were compared between inpatients with or without epistaxis.The factors with significant differences were analyzed by binary Logistic regression.The monthly average temperature,air pressure,humidity and 2-minute wind speed were collected from January 2021 to December 2022 in Naqu City to analyze the correlation between epistaxis and climate factors.Results The number of patients with hypertension in the case group was more than that in the control group,and the difference was significant(P=0.013).Serum Hcy level in the case group was higher than that in the control group(P<0.001).RBC,HCT,HGB and MCHC were lower than that in the control group(P=0.001,0.001,0.001,0.039),and the difference was significant.History of hypertension and Hcy were risk factors for epistaxis.Patients with a history of hypertension were 3.713 times more likely to suffer from epistaxis than those without a history of hypertension(P=0.022).Each 1 increase in Hcy concentration increased the risk of epistaxis by 13.1%(P=0.001).Conclusion Patients with epistaxis in Naqu area had higher serum Hcy level and lower RBC,HCT,HGB and MCHC.History of hypertension and Hcy were risk factors for epistaxis.Patients with a history of hypertension were 3.713 times more likely to suffer from epistaxis than those without a history of hypertension.Every 1 increase in Hcy concentration increased the risk of epistaxis by 13.1%.Active intervention of hypertension and serum Hcy can effectively prevent the incidence of epistaxis.
