[Occurrence of gene mutations in factor V Leiden, prothrombin and methylenetetrahydrofolate reductase in patients with pre-eclampsia].
OBJECTIVE
The aim of the study was to detect the incidence of thrombophilia FV Leiden, prothrombin G20210A, MTHFR C677T, resistance to activated protein C, and deficiency of protein C and S in pregnant or puerperal women with preeclampsia and control group.


METHODS
Case-control study.


METHODS
Department of Obstetrics and Gynecology, Department of Hemato-oncology, Medical Faculty, Palacký University, Olomouc.


METHODS
The group of 38 women with confirmed diagnosis of preeclampsia were examined for resistance to activated C protein. (Coatest, APC resistence Chromogenix), levels of C and S protein. For the detection of FV:Q506, prothrombin G20210A and MTHFR C677T allels was done by PCR test. The control group had 50 women, chosen randomly. The statistical evaluation was performed by the STATISTICA program. For the analyzing of the continuous variables the Student's T-test was used. Values below p < 0.01 were considered to be statistically significant.


RESULTS
Women who suffered from preeclampsia came to mean age of 32.8 +/- 4.3 (years), mean gestational age 33.6 +/- 2.8 (weeks), mean systolic pressure 163 +/- 21 mmHg, diastolic pressure 108 +/- 8 mmHg. All of the results were rendered to be statistically significant in comparison the control group. On the other hand, the results in observed haematologic parameters were not significant (Preeclampsia/controls). FV Leiden--heterozygous subjects 4/3, prothrombin G20210A 1/0, C677T heterozygous subjects 12P10, C677T 2/0, protein C and S deficiency 2(0. Resistance to activated C protein was found in 14 (37%) patients, in comparison to 6 (12%) in the control group (p = 0.0073).


CONCLUSIONS
We didn't find any difference in the prevalence of genetic mutations in patients with preeclampsia compared to the control group. The prevalence of APC resistance was statistically higher in preeclamptic patients compared to the control group.
