Collaborating to Improve Quality of Life in Primary Immunodeficiencies: World PI Week, 2013

World Primary Immunodeficiency Week (WPIW) 2013 ran from 22 to 29th April (www.worldpiweek.org), providing an opportunity to reflect on progress made and the challenges that remain for the primary immunodeficiency diseases (PID) community. In this article, representatives from leading PID societies evaluate the situation and plans for further progress in their respective areas of the world. It is hoped that this situation analysis will prompt further focus and enhanced collaboration on the gaps that remain in the pursuit of promoting early diagnosis and treatment of PIDs.
