低剂量叶酸对高同型半胱氨酸血症患者血浆同型半胱氨酸及趋化因子水平的影响

目的观察低剂量叶酸治疗对高同型半胱氨酸血症(HHcy)患者血浆同型半胱氨酸及趋化因子水平的影响。方法给予40名HHcy患者叶酸0.8mg/d治疗6个月,在治疗前、后分别采集空腹静脉血,检测血浆Hcy、叶酸、单核细胞趋化蛋白-1(MCP-1)、白细胞介素-8(IL-8)、超氧化物歧化酶(SOD)和丙二醛(MDA)水平。结果叶酸治疗6个月后,HHcy患者的血浆Hcy水平为(25.8±12.0)μmol/L,明显低于治疗前的(57.1±18.0)μmol/L(P<0.05)。患者的MCP-1、IL-8、SOD和MDA水平则在治疗前、后差异均无显著性。结论低剂量叶酸治疗可降低HHcy患者的Hcy水平,但对趋化因子的水平无影响。

Effect of low-dose folate treatment on plasma homocystyeine and chemokine levels in patients with hyperhomocysteinemia

OBJECTIVE: To explore the effect of low-dose folate on plasma homocysteinemia (Hcy) and chemokine levels in patients with hyperhomocysteinemia (HHcy). METHODS: Forty HHcy patients were treated with 0.8 mg/d folate for 6 months. Plasma levels of Hcy, monocyte chemoattractant protein-1 (MCP-1), interleukin-8 (IL-8), malondialdehyde (MDA), and superoxide dismutase (SOD) were measured before and after folate treatment. RESULTS: Plasma level of Hcy significantly decreased after folate treatment [(57.1 +/- 18.0) micromol/L vs (25.8 +/- 12.0) micromol/L, P <0.05]. However, the plasma levels of MCP-1, IL-8, SOD, and MDA were not changed after folate treatment. CONCLUSION: Folate treatment can decrease the plasma Hcy level in HHcy patients; however, it has no obvious effects on the chemokine levels.
