Hey Friends! Thank you for supporting me and helping me make a difference!!! Primary immunodeficiencies (PI) are a group of more than 400 rare, chronic disorders in which part of the body's immune system is missing or functions improperly. Because one of the most important functions of the normal immune system is to protect us against infection, patients with PI commonly have an increased vulnerability to infections, which can be recurrent, unusually severe, or won't clear up. People with PI can face frequent health problems and often develop serious and debilitating illnesses. The Immune Deficiency Foundation improves the diagnosis, treatment, and quality of life of people affected by primary immunodeficiency through fostering a community empowered by advocacy, education, and research. There are approximately 250,000 people who are diagnosed with PI in the U.S., and thousands more go undetected. Patients also experience difficulties financing their healthcare, finding educational materials on the disease and locating others with whom to share their experiences. IDF helps individuals overcome these difficulties. Thousands of individuals and families affected by PI depend on IDF for advocacy, education, and empowerment. IDF does not charge patients or healthcare professionals for the educational materials or local programming that it provides. This is possible because of the generosity of the donors and sponsors who make unrestricted gifts to IDF.
