The relationship between thrombophilic mutations and preeclampsia: a prospective case-control study

Area of Science:

• Obstetrics and Gynecology
• Hematology
• Genetics

Background:

• The association between preeclampsia and thrombophilia is debated due to conflicting study results.
• Previous research has varied in ethnic groups, selection criteria, and sample sizes, leading to inconsistent findings.

Purpose of the Study:

• To investigate the relationship between thrombophilia and preeclampsia in a specific regional population.
• To clarify the role of inherited thrombophilias in the development of preeclampsia.

Main Methods:

• A prospective case-control study compared 100 preeclamptic women with 100 normal pregnant women.
• Post-delivery, all participants were screened for Factor V Leiden, MTHFR, prothrombin gene mutations, and deficiencies in Protein C, Protein S, and Antithrombin III.

Main Results:

• Thrombophilic mutations were present in 42% of preeclamptic women and 28% of controls (P=0.27).
• No statistically significant differences were observed in the incidence of specific mutations (Factor V Leiden, MTHFR, prothrombin) or deficiencies (Protein C, S, Antithrombin III) between the groups.
• The odds ratio for thrombophilia in preeclampsia was 1.5 (95% CI 1.0-2.2).

Conclusions:

• This study found no significant difference in thrombophilic mutations between preeclamptic and normal pregnant women in the studied region.
• Based on these findings, routine thrombophilia screening for preeclamptic patients is not supported in this population.
• Further research may be needed to explore other potential risk factors for preeclampsia.
