Healthy Clinical Trial - The Effect of Blood Donation on Hematological &

Status Active, not recruiting

Clinical Trial Summary

Blood donations is a essential and crucial in the clinic. Normal biological variation of relevant biomarkers and hormones before the donation of 450 mL whole blood as well as the expected alterations in systemic levels of plasma iron indices and RBC measures up to 4 weeks after donation in healthy, non-anemic, young men and women is investigated Likewise, the possibilities for detecting autologous blood transfusion is investigated.

Clinical Trial Description

Blood donations is a essential and crucial in the clinic. A whole blood donation results in the loss of 450-525 mL whole blood in eight to ten minutes and is known to reduce body iron stores with 200-265 mg iron depending on the donor's age, hematocrit and sex and accounts for 25% of average tissue iron stores in men and up to 75% in women.In the present study, the investigators aimed at thoroughly evaluate normal biological variation of relevant biomarkers and hormones before the donation of 450 mL whole blood as well as the expected alterations in systemic levels of plasma iron indices and red blood cell measures up to 4 weeks after donation in healthy, non-anemic, young men and women Likewise, doping in sport is a major problem concerning both the health of the athletes and the integrity of sports. Despite major improvements in anti-doping work in recent years, it is still impossible to test for all existing and future doping strategies, such as manipulation with blood oxygen carrying capacity. A well-known doping strategy is autologous blood transfusion (ABT), and at present, the detection of ABT is a challenge for anti-doping authorities. The hypotheses for this study are that 1) ret% and abnormal blood profile score (ABPS) have higher sensitivity to micro-dose ABT compared to current variables in the Athlete Biological Passport (ABP); 2) The plasma concentration of hepcidin and erythroferrone (ERFE) is sensitive to micro-dose ABT; 3) Gender-specific variations in hematologic variables affect the interpretation of the athlete's biological passport. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
