Expected PI Week Deals
As a vital awareness initiative, PI Week focuses on fundraising and advocacy rather than commercial deals. Organizations like the Immune Deficiency Foundation (IDF) and the Jeffrey Modell Foundation lead efforts, often partnering with corporate sponsors for donation matching programs and awareness campaigns. Expect pharmaceutical companies specializing in immunology, such as CSL Behring and Takeda, to highlight patient support programs and educational resources. Retailers may offer roundup-at-checkout options or donate a portion of sales from specific products to PI research. We will update this page with confirmed live initiatives as April 2027 approaches, encouraging community involvement and support for this critical health cause.

History of PI Week
PI Week was founded to help raise awareness about primary immunodeficiencies and improve the lives of patients suffering from them. Primary immunodeficiencies are usually caused by hereditary genetic defects and can affect anyone. It means that regardless of age, gender, ethnicity, and environment, you can be affected by PI. All the different PIs share one common feature: disruption of the body’s immune system. PI weakens the immune system and increases the body’s susceptibility to infection. The infections may be in the skin, sinuses, throat, ears, lungs, brain, spinal cord, urinary tract, or intestinal tract. Symptoms of PI include frequent pneumonia, inflammation, blood disorders, digestive problems, delayed growth and development, and autoimmune disorders.
Living with PI is difficult for patients with PI as they commonly also have recurring infections that won’t go away or unusually severe infections. According to health experts, over six million people across the globe suffer from PI, and 70% to 90% of those with PI are still undiagnosed. Therefore, early diagnosis is crucial because it contributes significantly to improving the quality of life and care for people suffering from PI.
The first step in diagnosing PI is usually blood testing, where doctors can evaluate the patient’s immune system through additional tests, physical examinations, and reviews of the medical and family histories of the patient. As far as the treatment goes, immunoglobulin therapies are essential, life-long treatments for the majority of people with primary immunodeficiency.
