Five cases (3 men, 2 women) of late-onset variable immunodeficiency syndrome (CVID), characterized by similar clinical and immunological findings as well as histological demonstration of chronic granulomatous infection, are reported. All patients had frequent attacks of respiratory infections with recurrent bronchitis and pneumonia. In addition to predominating basally localized streaky-nodular lung changes all patients had hepatosplenomegaly and granulomatous infections of other organs. Immunologically, marked hypogammaglobulinaemia of all Ig classes, lymphopenia, and absence of terminal B-cell maturation were predominant. In-vitro tests under pokeweed-mitogen failed to demonstrate terminal plasma-cell differentiation of B-lymphocytes and thus Ig synthesis. Without pokeweed-mitogen there were largely nonsecretory B-blasts with abnormal granulated cytoplasmic Ig formation. Skin testing with Multitest application revealed almost complete anergy, both in the Arthus (24 h) and the late reactions (48 and 72 h). Nonetheless, T-cell reaction in-vitro was much less affected than B-cell function. "Natural killing" and antibody-dependent cytotoxicity were normal or slightly increased.

Mutations of the gene encoding the TNF receptor family member transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI), TNFSRF13B, have recently been described in patients with common variable immunodeficiency (CVID). We report the case of a man with CVID in association with a heterozygous TACI gene mutation (C104R) who had a highly unusual, invasive, polyclonal CD8+ T-cell lymphoproliferation resulting in massive hepatosplenomegaly and causing renal impairment because of infiltration. Although lymphoproliferation is well described in CVID, the key features in this patient included the T-cell origin of the lymphoproliferation, its polyclonal nature, its infiltration into multiple organs, and the presence of the TACI gene mutation.
