Humoral deficiencies represent a broad group of disorders. The aim of the study was to compare the levels of antibodies against pneumococcal capsular polysaccharides (anti-PCP) and natural anti-galactosyl (anti-Gal) antibodies in (1) patients with chronic lymphocytic leukaemia (CLL), (2) patients with common variable immunodeficiency (CVID), and (3) a healthy population and to explore their dia...

BACKGROUND AND OBJECTIVE Autoimmune disorders occur with a higher incidence in common variable immunodeficiency (CVID) patients than in the general population. To describe the clinical features of the autoimmune phenotype in patients with CVID. METHODS The hospital records of all diagnosed CVID patients referred to the Children's Medical Center Hospital in Tehran, Iran between 2000 and 2010 w...

We describe a girl, now 9 years of age, with chronic idiopathic thrombocytopenic purpura, persistent nonmalignant lymphadenopathy, splenomegaly, recurrent infections, and autoimmune hemolytic anemia. Her symptoms partly fit the definitions of both autoimmune lymphoproliferative syndrome (ALPS) and common variable immunodeficiency disorders (CVIDs). Genetic analysis showed no abnormalities in th...

Common variable immunodeficiency (CVID) is a heterogeneous group of disorders, characterized by hypogammaglobulinemia, defective specific-antibody production resulting in recurrent bacterial infections. Delay in diagnosis and inadequate treatment result in increased irreversible complications and mortality. To determine persistent morbidities, mortality rate and survival in Iranian patients wit...

One of the great advances in clinical medicine was the recognition of the pleomorphism of the immune response and the multiple afferent and efferent limbs of antigen processing and responsiveness. A significant contribution to this understanding was derived from studies of human immunodeficiency states, including both inherited and acquired syndromes. Amongst these syndromes, one of the most co...

BackgroundGranulomatous and lymphocytic interstitial lung disease (GLILD) is a life-threatening complication in patients with common variable immunodeficiency (CVID), but the optimal treatment unknown.ObjectiveOur aim was to determine whether rituximab azathioprine or mycophenolate mofetil improves high-resolution computed tomography (HRCT) chest scans and/or pulmonary function test results CVI...

Introduction Previous studies showed that several lymphocyte abnormalities seen in the most frequent symptomatic immunoglobulin deficiency, common variable immunodeficiency (CVID), were also observed in a genetically related asymptomatic disorder - selective IgA deficiency (IgAD). In this study we searched for abnormalities in the differentiation stages of T cells as well as for similarities of...

Case A 41-year-old male presented with abdominal pain, diarrhea, weakness, and shock. He was diagnosed with cardiac tamponade, underwent pericardial drainage and initiation of broad-spectrum antibiotics. The patient had a recent admission with bilateral pleural effusions, with negative infectious and malignancy workup. Macrocytic anemia, increased white blood cells, incidental abdominal abscess...

objective: common variable immunodeficiency (cvid) is one of the most frequent cases of primary immunodeficiency. it is likely that this heterogeneous disease is caused by several distinct genetic disorders. the activation-induced cytidine deaminase (aid) enzyme is involved in class switching, somatic hypermutation (shm) and processes associated with gene conversion in the germinal center. in o...
