Navigating the management complexity in long-term asymptomatic immunodeficiency

Abstract

Background: Common variable immunodeficiency disorder (CVID) is a condition associated with recurrent infections and non-infectious outcomes, including lung disease like bronchiectasis and granulomatous and lymphocytic interstitial lung diseases (GLILD), autoimmune disease, enteropathy, and lymphoma. Treatment involves initiation of replacement immunoglobulin (Ig), which is a lifelong commitment. Prior to Ig replacement, life expectancy for patients with CVID was less than 15 years. With replacement Ig, it has improved to over 50 years. In most cases, patients present to a clinician with a history of recurrent infections, and treatment is indicated. However, in patients with asymptomatic disease, the best timing to start treatment can be difficult to determine. Case: We present a case of an otherwise healthy male who had an incidental diagnosis of CVID. Results: Workup revealed hypogammaglobulinemia for over 30 year. Discussion: Though successful in reducing infections, Ig replacement can come with many side effects, as well as a heavy medical burden to the patient and the healthcare system. It is also a big life adjustment, and can greatly affect a patient's quality of life. In the military, a diagnosis of an immunodeficiency, and the need for monthly intravenous immunoglobulin (IVIG) can be detrimental to deployment readiness, and a patient's military career. Risks and benefits need to be weighed prior to initiating Ig therapy.
