The aim of the project was the assessment of clinical usefulness of the determination of blood serum homocysteine concentration, folic acid and vitamin B12 in recurrent miscarriages.


30 non-pregnant women with recurrent miscarriages (examined group-I) and for 20 non-pregnant women without obstetric failures in medical history (control group-II) were examined.


In the examined group (group I), the average concentration of homocysteine (9,45 micromol/l) was not statistically higher in comparison to the control group (group II) (8,47 micromol/l) (p>0,05). In group I the average vitamin B12 concentration in blood serum was 178,3 pg/ml and it was statistically lower (p<0,001) in comparison with the control group (II) (268,6 pg/ml). Such a relation was not observed for the vitamin B12, where the average concentration of this parameter was not dependent on the miscarriage number. A high negative correlation (R= -0,5397, p<0,01) was observed between the level of folic acid and homocysteine concentration in the group of women with recurrent miscarriages and a very high negative correlation (r = -0,9586 p<0,001) in the control group. No relation (R=0,0992 p>0,05) between the average concentration of vitamin B12 in blood serum and the average homocysteine in the nullipara group with recurrent miscarriages


Together with the increasing number of abortions, the average homocysteine concentrations grew and the average folic acid concentrations lowered.
