Correlation between ABO Blood Group, and Conventional Hematological and Metabolic Parameters in Blood Donors.

Background: Although several studies have investigated and confirmed the existence of an association between ABO blood type and several human disorders, especially with cardiovascular disease, little is known on the physiological influence or association of ABO blood groups on basal levels of some conventional hematological and metabolic parameters.

Study Design And Methods: A total number of 7,723 consecutive healthy blood donors underwent laboratory testing at the time of their first blood donation, which apart from ABO typing included assessment of alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, total bilirubin, total cholesterol, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), triglycerides, creatinine, iron, ferritin, uric acid, glucose, hemoglobin, and platelet count.

Results: The most relevant finding was the identification of significantly higher values of total cholesterol and HDL-c in subjects with blood group A compared with those with O blood type, with the highest levels being observed in A1 subtype.

[Haemostatic abnormalities and thyroid disorders: the prospective observational MITH study].

Haemostatic abnormalities are a common phenomenon in patients with thyroid diseases. On one hand the condition of hyperthyroidism is associated with an increased risk of thrombotic events, on the other in severe hypothyroidism can be found a haemorrhagic tendency, as opposed to the subclinical hypothyroidism seems to correlate with increased thrombotic risk. The prospective, single center, observational MITH study (Mantua Investigation on Thyroid and Haemostasis), whose results are presented, aims to evaluate coagulation parameters in patients with thyroid disease, to establish the prevalence of haemostatic abnormalities in various conditions, to analyse the implications and clinical response to therapy established.

[Clinical use of virally inactived plasma. The experience of Blood Transfusion Unit in Mantova, Italy].

Background: Fresh Frozen Plasma (FFP) is a blood component whose clinical use is widespread worldwide. Transfusion safety of this product is ensured by legally obligatory tests. Although these tests are carried out on each plasma donation, safety levels can be further improved by using some technical procedures, such as, among others, methylene blue (MB) and solvent-detergent (SD) viral inactivation methods.
