Primary immunodeficiency diseases (PIDDs) are a heterogeneous group of genetic disorders in which a component of the immune system is missing or not functioning properly, making a person more susceptible to infections, autoimmune disorders, and chronic inflammation.1 Although some PIDDs manifest in childhood, many patients do not receive a diagnosis until adolescence or adulthood, ofen after many years of suffering thru recurrent infections and health care utilization.
Early recognition of PIDDs is critical because delayed diagnosis may lead to organ damage, hospitalizations, and a poor quality of life. Pharmacists, as accessible health care providers in various settings, are in an ideal position to identify patients who may benefit from further immunologic evaluation and intervention.1

For patients with antibody deficiencies, the most common form of PIDD, immunoglobulin (Ig) replacement therapy
The role of the primary care physician (PCP) is vital in the quality of life of those suffering from PIDD. They are instrumental in early detection and appropriate Ig replacement therapy by playing a crucial role in the multidisciplinary care of PIDD patients,which will improve patient outcomes.

Protecting access to Immunoglobulin Therapy
What is Immunoglobulin Therapy?
Immunoglobulin therapy involves providing antibodies to individuals with weakened immune systems,typically those with primary immunodeficiency diseases. These antibodies help fight off infections and improve overall health. https://primaryimmune.org/about-primary-immunodeficiency-diseases/treatment-of-pid/immunoglobulin-therapy provides a detailed explanation of the therapy.
Current Challenges to Access (January 29, 2026)
Access to immunoglobulin therapy is currently facing significant challenges due to ongoing supply disruptions and changes in reimbursement policies.The FDA acknowledged these disruptions in a January 15, 2026, update, citing manufacturing issues and increased demand. Moreover, recent changes to Medicare Part B drug payment finalized on January 22, 2026, by CMS, may impact patient access and costs.
Advocacy Efforts by the Primary Immune Deficiency Treatment Center (PIDTC)
The PIDTC actively advocates for policies that protect patient
