Prostaglandin E2, trace elements and levels of oxidative processes in spontaneous miscarriages

Area of Science:

• Reproductive Biology
• Biochemistry
• Obstetrics

Background:

• Spontaneous miscarriages are a common complication of early pregnancy.
• Understanding the biochemical factors contributing to miscarriage is crucial for developing preventative strategies.

Purpose of the Study:

• To investigate the role of prostaglandin E2 (PGE2), trace elements, and oxidative stress parameters in spontaneous miscarriages.
• To compare these parameters between pregnancies with spontaneous abortion, missed abortion, and healthy pregnancies.

Main Methods:

• Analysis of plasma PGE2 concentrations using ELISA kits.
• Colorimetric analysis of plasma trace elements (copper).
• Assessment of lipid peroxidation and antioxidative enzyme activities (glutathione peroxidase, catalase, superoxide dismutase) in hemolysate.
• Statistical analysis using Student's t-test and ANOVA.

Main Results:

• Lower plasma PGE2 concentrations were observed in women with spontaneous and missed abortions compared to healthy pregnancies.
• Significantly lower plasma copper levels and reduced activity of antioxidative enzymes (glutathione peroxidase, catalase) were found in miscarriage groups.
• Increased lipid peroxidation products and altered superoxide dismutase levels were noted in women experiencing miscarriages.

Conclusions:

• Reduced levels of PGE2, copper, and key antioxidative enzymes, along with elevated lipid peroxidation, are associated with spontaneous miscarriages.
• These biochemical alterations may play a significant role in the etiology and potential prevention of miscarriage.
• Further research into these markers could lead to novel diagnostic and therapeutic approaches for recurrent pregnancy loss.
