Objective: Changes in target organ lesions, even beyond reduction of blood pressure, have been shown to have predictive value. Destiffening of arterial damage seems to be possible but the mechanisms are still elusive. We report changes in pulse wave velocity (PWV) after one year of treatment in new diagnosed previously untreated, hypertensive patients.
Design and method:We included in this longitudinal study 356 consecutive, nevertreated patients with suspected hypertension. After standard clinical assessment, including ambulatory blood pressure monitoring (ABPM), pulse wave analysis and PWV (Sphygmocor §, AtcorMedical), 231 showed elevated office and/or ambulatory blood pressure (BP) and received monotherapy treatment accordingly. 125 patients who showed to be normotensive, served as control group. Clinical assessment was repeated after a median of 1.1 years in the whole cohort. PWV was adjusted to BP.
Transfusion associated graft versus host disease (TA-GvHD) is a rare complication of transfusion treatment with blood products containing viable lymphocytes. The risk of developing TA-GvHD depends on number and sustainability of lymphocytes in blood product, host’s immune system reactivity and the difference in human leukocyte antigen (HLA) system between donor and recipient. Standard method of TA-GvHD prevention is irradiation of blood products with ionizing radiation and absorbed dose of 25-50 Gy. The aim of irradiation is inactivation of viable lymphocytes in blood product containing cells (red blood cells, platelets, granulocytes) and lymphocyte proliferation inhibition in blood product recipient. In the last two decades, gamma irradiation has been extensively abandoned and replaced with specially designed cabinet machines using X-ray irradiation which are suitable for hospital and blood bank use. This reduces the risk of accidental or deliberate misuse of radioactive source, solves radioactive waste disposal issues and reduces ionizing irradiation exposure of employees in blood establishments. In Blood Bank of Croatian Institute of Transfusion Medicine, X-ray irradiation of blood products has been carried out since 2014 with a year rate of 20,000 irradiated cell blood products used in treatment of patients at risk of developing TA-GvHD.
Background: Autoimmune hemolytic anemia (AIHA) is a rare autoimmune disease in which red blood cells (RBC) are targeted by autoantibodies confirmed with positive direct antiglobulin test (DAT), resulting in premature destruction of RBC. AIHA may be subdivided into warm antibody AIHA (wAIHA) and cold antibody AIHA (cAIHA), and also to primary and secondary depending on the presence of an underlying disorder. In addition to that, patients may have positive DAT but without features of hemolysis, and some of them will later develop AIHA. Aims: The aim of this study was to analyze characteristics of newly diagnosed DAT positive AIHA patients during the 5 years period in our tertiary center, as well to assess DAT positive patients without features of AIHA. Methods: This was a single-center retrospective cohort study performed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
