    Abstract:
    Patients with common variable immunodeficiency (CVID) can develop granulomatous-lymphocytic interstitial lung disease (GLILD), which is associated with increased morbidity and mortality. Treating GLILD is a significant challenge because it is rare and can be pathologically heterogeneous. Here we describe two cases of patients with CVID-associated GLILD with biopsies demonstrating loosely organized tertiary lymphoid structures (TLSs). Based on the pivotal role that B cells play in TLS initiation and maintenance, we hypothesized that using rituximab monotherapy for B-cell depletion alone would be sufficient for the disruption of the pathologic process underlying GLILD. These two cases demonstrate that adapting a strategy of B cell depletion monotherapy may be effective in TLS-associated conditions such as GLILD.
