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.

Common variable immunodeficiency disorder belongs to the most common primary human immunodeficiencies and it is characterized by primary defective immunoglobulin production. Hypogammaglobulinemia manifests in every age, usually in adult people. There is no gender predisposition. The prevalence is 1 : 25 000-1 : 50 000. The ethiopathogenesis of the majority of CVIDs is unknown. The main clinical respiratory symptoms include recurrent respiratory infects, especially bacterial etiology, sinusitis, bronchitis, pneumonia, leading to bronchiectasis and lung fibrosis. Interstitial lung fibrosis and granulomatosis often manifest at diagnosis of CVID and they are negative prognostic factors of the disease.

Common variable immunodeficiency is an antibody deficiency that usually presents in childhood with recurrent sino-pulmonary infections. Diagnostic delay is frequent and thus respiratory morbidity is common, ranging from recurrent suppurative bronchitis to bronchiectasis. Immunoglobulin replacement therapy is the mainstay of treatment, whilst prophylactic antibiotic therapy and muco-ciliary clearance are additional treatment options. This review examines the diagnosis and management of respiratory issues in children with CVID.
