Granulomas in Common Variable Immunodeficiency Display Different Histopathological Features Compared to Other Granulomatous Diseases

by

J Clin Immunol. 2024 Oct 7;45(1):22. doi: 10.1007/s10875-024-01817-3. ABSTRACT Granulomatous disease affects up to 20% of patients with Common Variable Immunodeficiency (CVID). Granulomas are comprised of highly activated immune cells, and emerge in response to antigenic triggers. In CVID granulomas however, the underlying pathophysiology is unclear and the specific trigger remains unknown. Granuloma formation in … Read more

Characteristics of Endemic Mycoses Talaromyces marneffei Infection Associated with Inborn Errors of Immunity

by

J Clin Immunol. 2024 Sep 26;45(1):17. doi: 10.1007/s10875-024-01798-3. ABSTRACT BACKGROUND: Talaromyces marneffei (T. marneffei) is an opportunistic pathogen that causes endemic mycoses, which could lead to multiple organ damage. Talaromycosis is frequently disregarded as an early cautionary sign of immune system disorders in non-HIV-infected children. OBJECTIVE: We conduct a comprehensive review of the genotypes and … Read more

Investigation of Transcription Factor and Cytokine Gene Expression Levels in Helper T Cell Subsets Among Turkish Patients Diagnosed with ICF2 (Novel ZBTB24 gene Variant) and ICF3 (CDCA7 Variant) Syndrome

by

J Clin Immunol. 2024 Sep 25;45(1):16. doi: 10.1007/s10875-024-01807-5. ABSTRACT Immunodeficiency, centromeric region instability, facial anomalies syndrome (ICF), is a rare disease with autosomal recessive inheritance. ICF syndrome. It has been reported that ICF syndrome is caused by mutations in the DNMT3B (ICF1), ZBTB24 (ICF2), CDCA7 (ICF3), and HELLS (ICF4) genes. As a result of literature … Read more

Biallelic PI4KA Mutations Disrupt B-Cell Metabolism and Cause B-Cell Lymphopenia and Hypogammaglobulinemia

by

J Clin Immunol. 2024 Sep 23;45(1):15. doi: 10.1007/s10875-024-01793-8. ABSTRACT PURPOSE: PI4KA-related disorder is a highly clinically variable condition characterized by neurological (limb spasticity, developmental delay, intellectual disability, seizures, ataxia, nystagmus) and gastrointestinal (inflammatory bowel disease and multiple intestinal atresia) manifestations. Although features consistent with immunodeficiency (autoimmunity/autoinflammation and recurrent infections) have been reported in a subset … Read more

Levels of Natural Antibodies Before and After Immunoglobulin Replacement Treatment Affect the Clinical Phenotype in Common Variable Immunodeficiency

by

J Clin Immunol. 2024 Sep 21;45(1):13. doi: 10.1007/s10875-024-01805-7. ABSTRACT Natural antibodies (NAbs) occurring in individuals without prior exposure to specific antigens, provide direct first barrier protection against pathogens, and exert immunoregulation thus actively contributing to the maintenance of immune homeostasis, controlling inflammatory processes and preventing autoimmunity. Common variable immunodeficiency (CVID) is a heterogeneous group of … Read more
