Common variable immunodeficiency (CVID) is a type of primary immunodeficiency that presents as a heterogenous disorder characterized by hypogammaglobinemia, poor response to vaccines, recurrent sinopulmonary infections, and can have noninfectious systemic manifestations. We performed a single-center, retrospective, observational study of five patients with noninfectious complications of CVID. All patients had CVID as defined by the European Society of Immunodeficiencies criteria and had received intravenous immunoglobulin therapy. There were multiple pulmonary manifestations of CVID including frequent pneumonias, bronchiectasis, granulomatous lung disease, and pulmonary hypertension. All our patients were treated with pulmonary vasodilators for severe precapillary pulmonary hypertension along with individualized immunosuppression regimen for interstitial lung disease. Despite treatment for interstitial lung disease and PH, their conditions worsened over 2-3 years with all patients progressing toward organ transplant evaluation. Idiopathic thrombocytopenia and non-cirrhotic portal hypertension were common, with three patients probably suffering from nodular regenerative hyperplasia. Noninfectious complications of CVID can affect different organs and progress despite advanced therapies. Single or multiorgan transplantation is a treatment option for patients with end-stage organ involvement refractory to medical therapy.
