Transfusion Transmitted Infectious Diseases

Aim

evaluate and advance safety of blood transfusion by analysing Transfusion Transmitted Infectious Diseases, coordinating international studies and publishing scientific reports

Following blood transfusion, there is a risk of transfusion-transmitted infectious diseases (TTID), despite current advanced screening technologies. Infectious agents involved are very diverse and include hepatitis B (HBV), hepatitis C (HCV), human immunodeficiency (HIV-1/2), human T-cell lymphotropic (HTLV-I/II), Cytomegalo- (CMV), Parvo- B19, West Nile (WNV) and Dengue viruses. Trypanosomiasis, malaria, and Transmissible Spongiform Encephalopathy (TSE) also belong to TTID. TTID can be reduced by donor exclusion, screening for serological infection markers or nucleic acid testing (NAT) by viral gene amplification. Despite this, blood-borne infectious agents are transmitted through transfusion of infected blood donated by apparently healthy and asymptomatic blood donors.

 

About

The Working Party on Transfusion Transmitted Infectious Disease (WP-TTID) focuses its activities on understanding infectious diseases in transfusion, including conducting research and assessments that contribute to increasing the safety of the blood supply across jurisdictions. We accomplish our work by bringing together international experts to: 1) gather, analyse and review relevant data; 2) develop and coordinate international studies; 3) publish scientific reports; and 4) to actively contribute to policy discussions, including advocacy for blood safety interventions in all regions of the world based on differences in epidemiology and resources. The WP-TTID members are scientific experts, regulators, company representatives and other participants from leading institutions in the fields of blood safety and infectious diseases

Subgroups

Our members participate in the following subgroups:

1) Bacteria

2) Parasites

3) Virology

4) Surveillance, Risk Assessment & Policy (SRAP), including surveillance for Prions/Transmissible spongiform encephalopathy (TSE)

 

Our Chairperson is Brian Custer.

Activities

We participate in subgroups and attend 1-2 day WP meetings linked to ISBT Congresses. Our subgroups develop and execute various surveys and laboratory experiments, analyse data with the intention to publish. Our subgroups discuss issues by conference call and in person. We sponsor Travel Awards and are launching a mentoring and training program for early/mid-career investigators, particularly from resource-limited countries.

Joining the WP

Applicants for membership must have a documented interest in TTID and preferably be involved in TTID surveillance or research. Equal representation of all world regions is a priority; we currently have over 120 members from  32 different countries.

Employees from pharmaceutical companies are only able to join as Corporate Sponsors.

Interested in joining the TTID WP? Please email the ISBT Office or our Chairperson.
