Waning Humoral Response 6 Month after Double Vaccination with the mRNA-BNT162b2 Vaccine in Hemodialysis Patients.

Introduction: Although most hemodialysis patients (HDP) exhibit an initial seroresponse to vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), studies have shown this response to be lower compared to healthy subjects. This fact raised concerns regarding the durability of the immune response and effective protection against severe Coronavirus disease 2019 (COVID-19) in this vulnerable population. The aim of our study was to evaluate the change in antibody levels over time in HDP population.

[Parallels in development of hemodialysis service and kidney transplantations in Lithuania during 1996-2005].

The aim of our study was to evaluate the changes in hemodialysis service, main demographic characteristics of hemodialysis patients in Lithuania during 1996-2005, and their correlation with the number of recipients on the kidney waiting list. During the study period, we annually visited all hemodialysis centers in Lithuania and collected data about all hemodialysis patients. There was a sharp increase in the number of hemodialysis centers (from 17 to 43), hemodialysis stations (from 25 to 100 per million population, P<0.

[Development of hemodialysis service in Lithuania during (1996-2003)].

The aim of our study was to evaluate the changes of hemodialysis (HD) service and main demographic characteristics of HD patients in Lithuania during seven years period. From 1996 to 2003 we visited annually all HD centers in Lithuania and collected data about all HD patients. There was a sharp increase in the number of HD centers (from 17 to 37), HD stations (from 25 p.
