OBJECTIVE: The present study investigates the prevalence of thrombophilia in individuals with first or/and second degree family history of thromboembolism. MATERIAL- METHODS: The study group consisted of 68 individuals with a first or second degree family history of venous or arterial thromboembolism, but without a personal history of thrombosis. The activity of ATIII, PC, PS, FVIII, FΧΙΙ and total homocysteine was measured on the ACL Advance coagulation analyzer. In addition, hemi-quantitative determination of CRP was performed to exclude an acute phase reaction. The existence of V-Leiden mutation was investigated by the modified pre-dilution method (1:5) with V-DEF. Prothrombin G20210A mutation was detected by the use of an in house PCR protocol. Family history was termed as follows: positive (thrombosis was reported in one parent and his/her family members) (group Α) or strongly positive (thrombosis was reported in both parents and their family members (group Β). RESULTS: Data analysis revealed decreased activity of ATIII:1.47%, PC:1.47%, and FXII:5.9%, increased activity of FVIII (without inflammation):11.8%, V-Leiden:13%, elevated Hcy:14.7%, and G20210A mutation:2.9%. Group A consisted of 55 individuals (74.5%), whereas group B of 16 (23.5%). The total percentage of thrombophilia was 48.5%, while the percentage within group A was 44.2% and within group B 62.5%. CONCLUSION: The high prevalence of thrombophilia, reinforce the importance of an extensive laboratory thrombophilia screening when a family history of thromboembolism has been recorded, especially when it concerns both parents and/or their family members and even more when one or more acquired thrombophilic factors coexist.
