Pediatric blood transfusions in Colombia: Dissecting adverse reaction trends and age dynamics.

Background: Adverse transfusion reactions (ATRs) represent undesired responses in patients. Different reports indicate that rates of ATRs are 1.3-2.

Blood transfusion dynamics in Colombia: Unveiling patterns, reactions and survival rates in multitransfused patients.

Background And Objectives: There is no consensus on a universally accepted threshold to categorize a patient as multitransfused. In 2019, Colombia established the definition of a multitransfused patient as someone who has received six or more blood components, irrespective of the time frame. This study aims to delineate the characteristics, adverse transfusion reactions (ATRs, definitions according to the International Society of Blood Transfusion [ISBT]) and survival rates in this population.

Role of disruptions in O RhD negative donations in Colombia on increasing maternal mortality ratio from haemorrhage.

Objective: The aim of this work was to evaluate the relationship of the maternal mortality ratio due to obstetric haemorrhage (MMROH) with the national blood donations, particularly O RhD negative (Oneg) before and during COVID-19 pandemic.

Background: The maternal mortality ratio is increasing in Colombia, yet little is known regarding the relationship between blood donations and maternal mortality due to obstetric haemorrhage.

Materials And Methods: A retrospective cross-sectional study between January 1, 2018, and December 31, 2021, was performed, to assess MMROH compared to the blood donations notified to the Colombian National Haemovigilance System, through non-parametric methods.

Prevention of multiple whole blood donations by an individual at the same month through the creation of a national Deferred Donor Registry (DDR).

Introduction: The Colombian National Institute of Health administers the National Information System of Haemovigilance (SIHEVI-INS). Today, SIHEVI-INS constitutes a national blood donor and recipient database, which contains a national deferred donor registry (DDR), allowing blood banks to take acceptance or rejection decisions of a potential donor in real time. The study aimed to determine the rate of people who have made more than one whole blood donation monthly in Colombia, violating the national guideline of intervals between donations (three months for men and four for women), since DDR implementation.

Effect of the first year of COVID-19 pandemic on the collection and use of blood components in Colombia monitored through the national haemovigilance system.

Objective: This work aimed to establish the effects of the COVID-19 pandemic on blood collection and blood product usage at the end of the first year.

Background: The arrival of SARS-CoV-2 to Colombia on March 6, 2020, triggered closure of borders and mandatory lockdown from March 23, 2020.

Methods/materials: The Colombian National Institute of Health administers the National database of confirmed cases of SARS-CoV-2 and the National Haemovigilance System.

Prevalence and incidence estimates for syphilis, chlamydia, gonorrhea, and congenital syphilis in Colombia, 1995-2016.

Objectives: To estimate adult (15-49 years old) prevalence and incidence of active syphilis, gonorrhea, and chlamydia, and incidence of congenital syphilis (CS) and adverse birth outcomes (ABOs) in Colombia, over 1995-2016.

Methods: The Spectrum-STI epidemiological model tool estimated gonorrhea and chlamydia prevalences as moving averages across prevalences observed in representative general population surveys. For adult syphilis, Spectrum-STI applied segmented polynomial regression through prevalence data from antenatal care (ANC) surveys, routine ANC-based screening, and general population surveys.

Prevalence of human T-cell lymphotropic virus I and II in Colombian blood donors, 2001-2014: Implications for transfusion safety.

Introduction: The human T-cell lymphotropic virus (HTLV) 1 and 2 cause various clinical disorders associated with degenerative diseases. Blood transfusion is a primary mechanism of transmission that is associated with the use of cellular components such as red blood cells. 

Objective: To describe the epidemiology of HTLV 1 and 2 in blood donors in Colombia from 2001-2014.
