Lung function trajectories in common variable immunodeficiencies: An observational retrospective multicenter study.

Background: Respiratory disease is a frequent cause of morbidity and mortality in common variable immunodeficiencies (CVIDs); however, lung function trajectories are poorly understood.

Objective: We sought to determine lung physiology measurements in CVIDs, their temporal trajectory, and their association with clinical and immunologic parameters.

Methods: This retrospective study from 5 Italian centers included patients with CVIDs who had longitudinal pulmonary function tests (PFTs) and chest computed tomography scan available.

Common and Uncommon CT Findings in CVID-Related GL-ILD: Correlations with Clinical Parameters, Therapeutic Decisions and Potential Implications in the Differential Diagnosis.

Purpose: To investigate computed tomography (CT) findings of Granulomatous Lymphocytic Interstitial Lung Disease (GL-ILD) in Common Variable Immunodeficiency (CVID), also in comparison with non-GL-ILD abnormalities, correlating GL-ILD features with functional/immunological parameters and looking for GL-ILD therapy predictive elements.

Methods: CT features of 38 GL-ILD and 38 matched non-GL-ILD subjects were retrospectively described. Correlations of GL-ILD features with functional/immunological features were assessed.

Severe Acute Respiratory Syndrome Coronavirus 2 Monoclonal Antibody Combination Therapy in Patients With Coronavirus Disease 2019 and Primary Antibody Deficiency.

Background: Previous reports highlighted the efficacy of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific monoclonal antibodies (mAbs) against coronavirus disease 2019.

Methods: We conducted a prospective study on the clinical outcome and antiviral effects of mAbs added to standard of care therapy in SARS-CoV-2-infected patients with primary antibody defects.

Results: Median time of SARS-CoV-2 quantitative polymerase chain reaction (qPCR) positivity was shorter in 8 patients treated with mAbs (22 days) than in 10 patients treated with standard of care therapy only (37 days, P=.

COVID-19 in complex common variable immunodeficiency patients affected by lung diseases.

Purpose Of Review: In the general population, the risk of severe COVID-19 is associated with old age, male sex, hypertension, obesity and chronic diseases. Chronic lung diseases are listed as additional risk factors for hospitalization and ICU admission. The purpose of this review is to define whether chronic lung diseases, such as bronchiectasis and interstitial diseases, represent a risk for a severe SARS-CoV-2 infection in patients affected by common variable immunodeficiency (CVID), the most common symptomatic primary antibody defect.

Vaccination in PADs.

Primary antibody deficiencies (PADs) are the most common primary immunodeficiencies (PIDs). They can be divided into the following groups, depending on their immunological features: agammaglobulinemia; common variable immunodeficiency (CVID) isotype; hyper IgM isotype; light chain or functional deficiencies with normal B cell count; specific antibody deficiency with normal Ig concentrations and normal numbers of B cells and transient hypogammaglobulinemia of infancy. The role of vaccination in PADs is recognized as therapeutic, diagnostic and prognostic and may be used in patients with residual B-cell function to provide humoral immunity to specific infective agents.

Granulomatous Lymphocytic Interstitial Lung Disease (GLILD) in Common Variable Immunodeficiency (CVID): A Multicenter Retrospective Study of Patients From Italian PID Referral Centers.

Granulomatous and Lymphocytic Interstitial Lung Diseases (GLILD) is a severe non-infectious complication of Common Variable Immunodeficiency (CVID), often associated with extrapulmonary involvement. Due to a poorly understood pathogenesis, GLILD diagnosis and management criteria still lack consensus. Accordingly, it is a relevant cause of long-term loss of respiratory function and is closely associated with a markedly reduced survival.

Women and acne: any difference from males? A review of the literature.

Introduction: The attention to the impact of gender differences in acne is needed and, at the moment, lacking. The aim of this paper was to perform a systematic review on gender differences in acne.

Evidence Acquisition: A review of the literature was performed using the PubMed and Ovid literature search engines , using a variety of combined search terms including "acne", "gender", "sex", "females", "males".

BRAF and NRAS mutations are heterogeneous and not mutually exclusive in nodular melanoma.

Inhibitors of RAF inhibit the MAPK pathway that plays an important role in the development and progression of those melanoma carrying the V600E BRAF mutation, but there's a subset of such patients who do not respond to the therapy. Various mechanisms of drug resistance have been proposed which include the clonal heterogeneity of the tumor. We have studied a population of nodular melanoma to investigate the intratumor and intertumor heterogeneity by Laser Capture Microdissection (LCM) analysis.

Correlations between psoriasis and inflammatory bowel diseases.

For a long time the relationship between inflammatory bowel diseases (IBDs) and psoriasis has been investigated by epidemiological studies. It is only starting from the 1990s that genetic and immunological aspects have been focused on. Psoriasis and IBD are strictly related inflammatory diseases.
