X-Linked Agammaglobulinemia: Infection Frequency and Infection-Related Mortality in the USIDNET Registry

Journal of Clinical Immunology, 2022
X-linked agammaglobulinemia (XLA) is a primary immunodeficiency disorder caused by mutations in the Bruton tyrosine kinase (BTK) gene leading to B lymphocyte deficiency and susceptibility to infection.

Infections With Enterohepatic Non-H. pylori Helicobacter Species in X-Linked Agammaglobulinemia: Clinical Cases and Review of the Literature

Frontiers in Cellular and Infection Microbiology, 2022
The genus Helicobacter is classified into two main groups according to its habitat: gastric and enterohepatic. Patients with X-linked agammaglobulinemia (XLA) appear to be associated with invasive infection with enterohepatic non-Helicobacter pylori ...

Clinical periodontal diagnosis

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

A possible role for B cells in COVID-19? Lesson from patients with agammaglobulinemia

Journal of Allergy and Clinical Immunology, 2020
COVID-19 had a mild clinical course in patients with Agammaglobulinemia lacking B lymphocytes, whereas it developed aggressively in Common Variable Immune Deficiency. Our data offer mechanisms for possible therapeutic targets.

Two X‐linked agammaglobulinemia patients develop pneumonia as COVID‐19 manifestation but recover

Pediatric Allergy and Immunology, 2020
The recent SARS‐CoV‐2 pandemic, which has recently affected Italy since February 21, constitutes a threat to normal subjects, as the coronavirus disease‐19 (COVID‐19) can manifest with a broad spectrum of clinical phenotypes ranging from asymptomatic ...

Longitudinal study of a SARS-CoV-2 infection in an immunocompromised patient with X-linked agammaglobulinemia

medRxiv, 2021
C-reactive protein (CRP) levels are elevated following bacterial infections but may be attenuated by the IL-6-receptor antagonist tocilizumab. In hospitalised COVID-19 patients, tocilizumab induced a transient (

A Novel BLNK Gene Mutation in a Four-Year-Old Child Who Presented with Late Onset of Severe Infections and High IgM Levels and Diagnosed and Followed as X-Linked Agammaglobulinemia for Two Years

Case Reports in Immunology, 2022
Agammaglobulinemia is a rare inherited immunodeficiency disorder. Mutations in the BLNK gene cause low levels of mature B lymphocytes in the peripheral blood leading to recurrent infections.

X-linked agammaglobulinemia

Definitions, 2020
X-linked agammaglobulinemia (XLA) is a condition that affects the immune system and occurs almost exclusively in males. People with XLA have very few B cells, which are specialized white blood cells that help protect the body against infection.

A novel mutation in SLC39A7 identified in a patient with autosomal recessive agammaglobulinemia: The impact of the J Project

Pediatric Allergy and Immunology, 2022
ZIP7 deficiency is the most recently described congenital agammaglobulinemia with autosomal recessive inheritance. 1 ZIP7, en-coded by SLC39A7 , is an endoplasmic reticulum- to- cytoplasm Zn 2 + transporter. Developing B cells are sensitive to altered Zn
