ABSTRACT
Background: The safety of blood products is the most important task of transfusion medicine. Transfusion-transmitted diseases represent a serious public health problem throughout the world, although their percentage of transmission is minimal. Each blood donation is individually tested with serological and molecular tests for the presence of hepatitis B and C viruses, human immunodeficiency virus (HIV), and Treponema Pallidum, regardless of the number of blood donations. Objective: To determine the seroprevalence of blood-borne diseases in healthy blood donors at the University Clinical Center Tuzla, to analyze the possible causes of transmission of these diseases, and to compare with the results of research in countries in the region and beyond. Methods: The research was conducted retrospectively in the period January 1, 2018. until 31.12.2022. years. Samples of blood donors were tested for hepatitis B surface antigen (HBsAg), antibodies to human immunodeficiency virus (HIV1/2), antibodies to hepatitis C and syphilis, using the fourth generation ELISA method. Results: The highest frequency of transmisive disease markers was reactivity to HBsAg with a total of 63.7% of cases and a prevalence of 0.13%, and the lowest for HIV with a total of 1.4% and a prevalence of 0.003%. Conclusion: Bosnia and Herzegovina has a very low seroprevalence but there is still a risk of disease transmission in the population.
ABSTRACT
UNLABELLED: Anatomical variations of veins often play a crucial role in formation of thrombotic changes in superficial and deep veins of lower extremities. THE AIM of this study was to determine the frequency of the dominant type of the lower extremity superficial veins, and to determine the eventual influence of such variations to the formation of superficial and deep vein thrombosis (DVT). MATERIAL AND METHODS: The sample used in this study consisted of 180 patients subjected to ascedent contrast phlebography of lower extremities. The total sample was divided into following groups: patients with and without variations of the lower extremity superficial veins. RESULTS AND DISCUSSION: Dominant type of the superficial veins (without variation) consisted of 97 patients (53.89%), while the rest of 83 patients showed some kind of anatomical variation (46.11%). The most frequent variation was the duplicated form ofv. saphena magna in 53.85%, while this procentage in women was 57.89%. Most frequent variations of duplicated v. saphena magna were: simple duplicated form, closed loop form, branching form and combined form. Topographical variation of saphenopopliteal junction besides fossa poplitea in the group of men showed procentage of 53.85%, while in the group of women that value accounted 63.16%. CONCLUSION: The percentage of varicose veins was more frequent in men and women without variations, but deep vein DVT showed higher frequency in patients with anatomical variations of superficial veins of lower extremities.
