the Association Between Blood's and Urinary Heavy Metal Level in Pregnant Women and the Spontaneous Abortion

• Conditions: Heavy Metal Toxicity; Spontaneous Abortion

• Registration Number: NCT03332706
• Lead Sponsor: Peking Union Medical College Hospital

Brief Summary

The aim of the study was to define the possible association between heavy iron level and the consequence of pregnancy especially spontaneous abortion and missed abortion. The study population will comprised the first-trimester pregnant women in the PUMCH (Peking Union Medicine College Hospital) during 2017 October to 2018 November. We categorised the patients into two groups, the study group where the patients suffered from spontaneous abortion or missed abortion, and the control group where the patients carry the normal live fetal for at least 8 weeks and ask for artificial abortion. All the cases included in the study were examined with respect to 6 kinds of heavy iron level in venous blood and urine, then correlation analysis was applied to define heavy iron level between two groups.
