To measure erythrocyte folate content and serum folic acid and homocysteine (Hcy) levels in preeclamptic primigravidae teenagers living at high altitude.
Measured analytes were compared to those found in normal teen controls.
Teenagers complicated with preeclampsia displayed significantly lower hematocrit and erythrocyte folic acid levels with higher serum Hcy levels as compared to controls (36.40 ± 4.90 vs. 38.99 ± 2.89 %, 493.80 ± 237.30 vs. 589.90 ± 210.60 ng/mL, and 7.29 ± 2.52 vs. 5.97 ± 1.41 μmol/L, respectively, p < 0.05). There was a non-significant trend for lower serum folic acid levels among preeclampsia teenagers. Serum and erythrocyte folic acid levels positively correlated in preeclampsia teenagers, and levels of both analytes inversely correlated with Hcy levels.
This pilot study found that teenagers complicated with preeclampsia living at higher altitude displayed lower erythrocyte folate content in addition to higher serum Hcy levels. More research is warranted to determine the clinical implications of these findings.
测量居住在高海拔地区的子痫前期青少年的红细胞叶酸含量以及血清叶酸和同型半胱氨酸(Hcy)水平。
将检测到的分析物与正常青少年对照组进行比较。
与对照组相比,患有子痫前期的青少年的红细胞比容和红细胞叶酸水平显著降低,而血清 Hcy 水平升高(36.40±4.90 比 38.99±2.89%,493.80±237.30 比 589.90±210.60ng/mL,7.29±2.52 比 5.97±1.41μmol/L,均为 p<0.05)。子痫前期青少年的血清叶酸水平呈下降趋势,但无统计学意义。子痫前期青少年的血清和红细胞叶酸水平呈正相关,而这两种分析物的水平与 Hcy 水平呈负相关。
这项初步研究发现,居住在高海拔地区的患有子痫前期的青少年除了血清 Hcy 水平升高外,红细胞叶酸含量也较低。需要进一步研究以确定这些发现的临床意义。
