GLILD

X-linked inhibitor of apoptosis protein (XIAP) deficiency is an inborn error of immunity (IEI). Allogeneic hematopoietic cell transplantation (HCT) is currently the only curative therapy available for XIAP deficiency. Granulomatous and lymphocytic interstitial lung disease (GLILD) is a common immune-related lung complication of IEIs. We present a 6-year-old boy with XIAP deficiency and GLILD. Computed tomography showed lung nodes but no symptoms. Before HCT, GLILD was not managed with immunosuppressive therapy, because he was asymptomatic...

BACKGROUND: Patients with primary antibody deficiency (PAD) frequently suffer from pulmonary complications, associated with severe morbidity and mortality. Hence, regular pulmonary screening by computed tomography (CT) scanning is advised. However, predictive risk factors for pulmonary morbidity are lacking. OBJECTIVE: To identify PAD patients at risk for pulmonary complications necessitating regular CT screening. METHODS: A retrospective longitudinal cohort study of PAD patients (median follow-up 7...

Our objective in this review is to familiarize radiologists with the spectrum of initial and progressive CT manifestations of pulmonary complications observed in adult patients with primary immunodeficiency diseases, including primary antibody deficiency (PAD), hyper-IgE syndrome (HIES), and chronic granulomatous disease (CGD). In patients with PAD, recurrent pulmonary infections may lead to airway remodeling with bronchial wall-thickening, bronchiectasis, mucus-plugging, mosaic perfusion, and expiratory air-trapping...

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...

Late-onset combined immunodeficiency (LOCID), considered now a subset of common variable immunodeficiency (CVID) disorders, is characterized by a predominantly T-cell immune defect. LOCID has a distinct phenotype from CVID with a greater risk of lymphoproliferative complications. As compared to the CVID cohort, LOCID patients also have increased rates of splenomegaly and granulomatous disease. We report a case of central nervous system (CNS) T-cell lymphoma in a 67-year-old male as the presenting manifestation of LOCID...

Granulomatous lymphocytic interstitial lung disease (GLILD) represents a fatal immune dysregulatory complication in common variable immunodeficiency (CVID). Evidence-based diagnostic guidelines are lacking, and GLILD treatment consists in immunosuppressive drugs; nonetheless, therapeutical strategies are heterogeneous and essentially based on experts' opinions and data from small case series or case reports.We aimed to evaluate the efficacy and safety of first-line Rituximab monotherapy for CVID-related GLILD, by assessing symptoms and quality of life alterations, immunological parameters, pulmonary function tests, and lung computed tomography...

INTRODUCTION: Common variable immunodeficiency related interstitial lung disease (CVID-ILD, also referred to as GLILD) is generally considered a manifestation of systemic immune dysregulation occurring in up to 20% of people with CVID. There is a lack of evidence-based guidelines for the diagnosis and management of CVID-ILD. AIM: To systematically review use of diagnostic tests for assessing patients with CVID for possible ILD, and to evaluate their utility and risks...

PURPOSE: A subset of common variable immunodeficiency (CVID) patients either presents with or develops autoimmune and lymphoproliferative complications, such as granulomatous lymphocytic interstitial lung disease (GLILD), a major cause of morbidity and mortality in CVID. While a myriad of phenotypic lymphocyte derangements has been associated with and described in GLILD, defects in T and B cell antigen receptor (TCR/BCR) signaling in CVID and CVID with GLILD (CVID/GLILD) remain undefined, hindering discovery of biomarkers for disease monitoring, prognostic prediction, and personalized medicine approaches...

INTRODUCTION: Patients with common variable immunodeficiency (CVID) have a high frequency of inflammatory complications like autoimmune cytopenias, interstitial lung disease and enteropathy. These patients have poor prognosis and effective, timely, and safe treatment of inflammatory complications in CVID is essential, but guidelines and consensus on therapy are often lacking. AREAS COVERED: This review will focus on current medical treatment of inflammatory complications in CVID and point out some future perspectives based on literature indexed in PubMed...

Granulomas have been defined as inflammatory infiltrates formed by recruitment of macrophages and T cells. The three-dimensional spherical structure typically consists of a central core of tissue resident macrophages which may merge into multinucleated giant cells surrounded by T cells at the periphery. Granulomas may be triggered by infectious and non-infectious antigens. Cutaneous and visceral granulomas are common in inborn errors of immunity (IEI), particularly among patients with chronic granulomatous disease (CGD), combined immunodeficiency (CID), and common variable immunodeficiency (CVID)...

Common variable immunodeficiency (CVID) is the most prevalent primary immunodeficiency. We present a 22-year-old Caucasian woman with CVID and granulomatous lymphocytic interstitial lung disease who contracted COVID-19 and was successfully treated with sotrovimab and molnupiravir. This treatment may have contributed to the relatively mild disease course of COVID-19 in our patient.

BACKGROUND: The range of pulmonary complications beyond infections in pediatric immunocompromised patients is broad but not well characterized. Our goal was to assess the spectrum of disorders with a focus on interstitial lung diseases (ILD) in immunodeficient patients. METHODS: We reviewed 217 immunocompromised children attending a specialized pneumology service during a period of 23 years. We assigned molecular diagnoses where possible and categorized the underlying immunological conditions into inborn errors of immunity or secondary immunodeficiencies according to the IUIS and the pulmonary conditions according to the chILD-EU classification system...

Teaching Point: Granulomatous lymphocytic interstitial lung disease is a non-infectious complication of common variable immunodeficiency. Computed tomography (CT) has an important diagnostic value by demonstrating pulmonary nodules, ground glass opacities, bronchiectasis, subpleural reticulations, lymphadenopathy and splenomegaly.

BACKGROUND: Prophylactic vaccination has proven to be the most effective strategy to fight the COVID-19 pandemic. METHODS: This was a prospective observational cohort study involving 30 predominantly antibody deficiency disorders (ADD)-afflicted adult patients on immunoglobulin replacement therapy vaccinated with three doses of the mRNA-1273 COVID-19 vaccine, and 10 healthy controls. Anti-RBD IgG antibodies were determined in plasma samples collected just before the first dose of mRNA-based COVID-19 vaccine and on weeks 4, 8, 24, and 28 following the first vaccination...

AIM: The aim of the study was to evaluate the response in lung function to different treatment regimens for common variable immunodeficiency patients with granulomatous lymphocytic interstitial lung disease (GLILD). METHOD: A longitudinal retrospective cohort study was carried out. Patients were divided into three groups. To assess the response to different treatments, we compared baseline lung function with post-treatment tests. RESULTS: 14 patients with GLILD were included, seven of whom were treated with acute corticosteroids for a mean duration of 132±65 days...

BACKGROUND: Common variable immunodeficiency disorders (CVID) are a group of primary immunodeficiencies characterized by impaired immunoglobulin production and dysregulated immune response. Neurological manifestations have been described in a few patients, and little is known about its clinic and therapeutic approach. Thus, this work aimed to review the literature on it and to help differentiate CVID from its mimics, especially sarcoidosis. METHODS: We described a case report and included a literature review of inflammatory neurological involvement in CVID...

Common variable immunodeficiency (CVID) causes granulomatous-lymphocytic interstitial lung disease (GLILD) and has a poor prognosis. We herein report a case of GLILD in a 49-year-old woman with CTLA-4 deficiency-associated CVID. The patient presented with dyspnea that had worsened over the past two years. A laboratory examination revealed hypoglobulinemia and pancytopenia. Chest computed tomography showed diffuse infiltrative and granular shadows in the bilateral interstitium. A flow cytometric analysis of blood cells and genetic testing confirmed CTLA-4 deficiency...
