Article Synopsis
  • - Mutations in the RAC2 protein are linked to various immune disorders in patients, including neonatal SCID and infantile diseases resembling leukocyte adhesion deficiency, with 15 new mutations identified among 54 patients studied.
  • - The study highlighted that different types of mutations in RAC2 influenced disease outcomes; for instance, certain mutations led to neonatal SCID while others caused later-onset combined immune deficiency or LAD-like diseases.
  • - Clinical analysis revealed significant immune system issues among affected patients, including low levels of T and B cells, recurrent infections, and abnormalities in neutrophil function, indicating severe impacts on their immune response.

Background: Severe asthma (SA) has been identified as a risk factor for severe systemic reactions (SR) to allergen subcutaneous immunotherapy (SCIT). However, the incidence and characterization of SRs in SA in comparison to less severe or no asthma is not known.

Objective: The objective of this study was to characterize the incidence of SRs in patients with SA receiving SCIT in comparison to patients with no asthma or less SA.

Granulomatous-Lymphocytic Interstitial Lung disease (GLILD) is a granulomatous and lymphoproliferative condition occurring in ~25% of Common Variable Immunodeficiency (CVID) patients with the highest prevalence in the late teen to young adult years. GLILD was first described in adults and carries a poor prognosis with survival estimated to be reduced by half. Here we report a pediatric case of CVID-associated GLILD that presented with rapid deterioration over 3 months and responded to adult-based treatment with dual chemotherapeutic agents (rituximab and azathioprine), resulting in complete resolution of clinical findings and near complete resolution of radiologic findings.

Background: Prior research suggests a possible association between asthma and depression.

Objective: To examine the association between asthma and depressive symptoms, controlling for asthma medications, lung function, and overall health.

Methods: We conducted a cross-sectional study of 12,944 adults who completed physician-based preventive health examinations at the Cooper Clinic from 2000 to 2012.

Purpose Of Review: The purpose of the review is to review the pathophysiology, available data, and our current recommendations for calcineurin inhibitor (cyclosporine and tacrolimus) treatment in antihistamine refractory chronic idiopathic urticaria (CIU) patients.

Recent Findings: Low-dose cyclosporine (<5  mg/kg per day) may have unique immunological modulating properties beyond mast cell and basophil stabilization in CIU. Starting CIU treatment with very low cyclosporine dosages (1 mg/kg per day) and titrating based on response and side-effects may decrease adverse events while preserving efficacy.
