Relationship between thyroid hormone level and urine protein quantitation in patients with severe preeclampsia / 中国基层医药

ABSTRACT

Objective To study the relationship between thyroid hormone level and 24h urine protein quanti-tation in patients with severe preeclampsia. Methods From August 2015 to October 2017,180 patients with severe preeclampsia who were treated in the Third People's Hospital of Qingdao were selected. The level of thyroid-stimula-ting hormone ( TSH) was detected by chemiluminescence particles immune method. According to the test results,the patients were divided into normal group (n=110,TSH=0. 3-3. 3mU/L) and hypothyroidism group (n=70,TSH>3. 3mU/L). Another 240 healthy pregnant women who admitted in the Third People's Hospital of Qingdao during the same period were selected as control group. The TSH,free triiodothyronine (FT3),free thyroxine (FT4) levels and 24h urine protein quantitation were compared among the three groups. The correlation between the level of thyroid hormone and 24h urine protein quantitation,the results of thyroid autoantibody in patients with severe preeclampsia were analyzed.Results The FT4,FT3 levels in the normal group were (11.92±2.54)pmol/L,(5.22 ±1.25)pmol/L, respectively,which in the hypothyroidism group were (9. 02 ± 1. 09) pmol/L,(3. 92 ± 1. 57) pmol/L,respectively, which were all lower than those in the control group (t=6. 657,16. 758,13. 221,18. 245,all P<0. 05),which in the hypothyroidism group were lower than those in the normal group (t=9. 031,6. 149,all P<0. 05). The TSH,24h urine protein quantitation levels in the normal group were (2. 56 ± 0. 86) mU/L,(66. 51 ± 18. 52) mg,respectively, which in the hypothyroidism group were (5. 87 ± 3. 02) mU/L,(79. 14 ± 12. 58) mg,respectively,which were all higher than those in the control group(t=2. 330,7. 197,16. 417,13. 335,all P<0. 05),which in the hypothyroidism group were higher than those in the normal group (t=10. 883,5. 014,all P<0. 05). There was positive correlation between serum TSH and 24h urine protein quantitation in patients with severe preeclampsia (r=0. 254,P=0. 001). There was negative correlation between FT4 and 24h urine protein quantitation (r= -0. 182,P=0. 025). There was no correlation between serum FT3 and 24h urine protein quantitation (r= -0. 080,P=0. 330). The positive rates of TPO Ab,TG Ab were 12. 86％,18. 57％ in hypothyroidism group,there were no statistically significant differences compared with 10. 91％,14. 55％ in the normal group (χ2 =0. 158,0. 513;P=0. 691,0. 474). Conclusion There is correlation between thyroid hormone levels and 24h urine protein quantitation in patients with severe preeclampsia. It has great significance for clinical treatment of severe preeclampsia by detecting the level of thyroid hormone.
