Sickle cell disease (SCD) is associated with oxidative stress due to an imbalance between production and elimination of the reactive oxygen species. It has been reported that SCD patients are at risk of multiple micronutrients' deficiencies, including several trace elements involved in the antioxidation mechanisms. We aimed to assess the status of these micronutrients in SCD patients. This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The databases of MedLine, Embase, and PsycInfo were used for the systematic search from time the databases existed until April 2021. A total of 36 studies fulfilled the eligibility criteria. We calculated the pooled standardized mean difference (SMD) of serum zinc, magnesium, or copper levels among patients with SCD and their healthy controls. SCD patients had significantly lower zinc (SMD = -1.27 [95% CI: 1.67-0.87, 0.001]) and magnesium levels (SMD = -0.53 [95% CI: 1.0-0.06, 0.026] than their controls. Copper level was found to be significantly higher in SCD patients, with SMD = 0.68 (95% CI: 0.05-1.32, 0.004). This review showed that SCD patients may potentially prompt to have lower zinc and magnesium levels and higher copper levels compared with those without the disease. Future research need to be directed to investigate clinical outcome of nutritional difficiencies in patients with SCD, as well as the possibility of implementing nutritional supplement programs which may help minimizing the harmful effects of the disease on human body.
镰状细胞病(SCD)与氧化应激有关,这是由于活性氧的产生和消除之间失衡所致。据报道,SCD患者存在多种微量营养素缺乏的风险,包括参与抗氧化机制的几种微量元素。我们旨在评估SCD患者这些微量营养素的状况。
本研究按照系统评价和Meta分析的首选报告项目(PRISMA)指南进行。使用MedLine、Embase和PsycInfo数据库进行系统检索,检索时间从数据库建立至2021年4月。共有36项研究符合纳入标准。我们计算了SCD患者及其健康对照者血清锌、镁或铜水平的合并标准化均数差(SMD)。
SCD患者的锌水平(SMD = -1.27 [95% CI:-1.67至-0.87,P = 0.001])和镁水平(SMD = -0.53 [95% CI:-1.0至-0.06,P = 0.026])显著低于其对照者。发现SCD患者的铜水平显著更高,SMD = 0.68(95% CI:0.05至1.32,P = 0.004)。
本综述表明,与未患该病的患者相比,SCD患者可能更容易出现锌和镁水平较低以及铜水平较高的情况。未来的研究需要致力于调查SCD患者营养缺乏的临床后果,以及实施营养补充计划的可能性,这可能有助于将该疾病对人体的有害影响降至最低。
