简介:摘要目的探讨血清维生素B12作为无创指标预测肝硬化伴食管胃静脉曲张患者远期再出血预后的价值。方法纳入2016年12月1日至2017年12月31日因肝硬化食管胃静脉曲张出血至复旦大学附属中山医院接受内镜治疗预防再出血并行血清维生素B12、叶酸检测的患者。对患者内镜之后3年再出血进行ROC曲线、Kaplan-Meier生存分析、单因素及多因素Cox回归分析,探讨不同维生素B12水平预测3年静脉曲张再出血的价值。结果共纳入115例患者,ROC曲线分析提示血清维生素B12预测3年再出血的最佳截断值为567.25 pg/ml。根据截断值将患者分为高维生素B12水平组(n=49)和低维生素B12水平组(n=66)。与维生素B12低水平组比较,维生素B12高水平组患者白蛋白水平偏低,男性比例更少(63.3% vs 80.3%),3年再出血率更高(P<0.05)。Cox分析提示维生素B12及血小板是静脉曲张出血患者3年再出血的独立预后因素。结论外周血维生素B12升高预示肝硬化食管胃静脉曲张患者更高的远期再出血风险。

简介:AbstractCOVID-19 has become a pandemic and it has already spread to at least 171 countries/regions. Chronic kidney disease (CKD) is a global public health problem with a total of approximately 850 million patients with CKD worldwide and 119.5 million in China. Severe COVID-19 infection may damage the kidney and cause acute tubular necrosis, leading to proteinuria, hematuria and elevated serum creatinine. Since the SARS-CoV-2 enters the cells by binding to the angiotensin-converting enzyme 2 receptor, some doctors question its ability to increase the risk and severity of developing COVID-19. Neither clinical data nor basic scientific evidence supports this assumption. Therefore, patients who take angiotensin-converting enzyme inhibitor or angiotensin receptor blocker are not advised to change their therapy. Patients with CKD are generally the elderly population suffering from multiple comorbidities. Moreover, some patients with CKD might need to take glucocorticoids and immunosuppressants. Dialysis patients are recurrently exposed to a possible contaminated environment because their routine treatment usually requires three dialysis sessions per week. Considering all the above reasons, patients with CKD are more vulnerable to COVID-19 than the general population. The development of COVID-19 may worsen the impaired kidney function and further lead to rapid deterioration of kidney function and even death. Strict comprehensive protocols should be followed to prevent the spread of COVID-19 among patients with CKD. In this review, we provide some practical management recommendations for health care providers, patients with CKD, dialysis patients and dialysis facilities.
简介:AbstractRespiratory health in the general population declines regardless of the presence of pulmonary diseases. Oxidative stress has been implicated as one of the mechanisms involved in respiratory dysfunction. This review was to evaluate studies that relate oxidative stress factors with pulmonary function among the general population without prior respiratory illnesses. The search yielded 54 citations. Twenty-one studies qualified for incorporation in this review. Owing to the heterogeneity of the review, studies were discussed based on identified oxidative stress factors responsible for pulmonary dysfunction. Oxidative stress biomarkers, including gene polymorphisms of nuclear factor erythroid 2-related factor 2, heme oxygenase 1, glutathione S transferase, superoxide dismutase, and lipid peroxidation products were involved in lung function decline. In addition, the antioxidant status of individuals in reference to dietary antioxidant intake and exposure to environmental pollutants affected oxidative stress and pulmonary function, as indicated by forced expired volume in one second, forced vital capacity, and forced expiratory flow at 25%-75%. This review indicated that oxidative stress is implicated in the gradual decline of lung function among the general population, and gene polymorphism along the antioxidant defense line and/or their interaction with air pollutants reduce lung function. Different polymorphic forms among individuals explain why the rate of lung function decline differs among people. Dietary antioxidants have respiratory health benefits in antioxidant gene polymorphic forms. Therefore, the genetic composition of an individual may be considered for monitoring and identifying people at risk of respiratory illnesses.
