Background: Primary antibody deficiency, the most common primary immunodeficiency disorder, represents a heterogeneous spectrum of conditions caused by a defect in any critical stage of B cell development and is characterized by impaired production of normal amounts of antigen-specific antibodies. Objective: This retrospective study aimed at description and analysis of demographic, clinical, im...

Common variable immunodeficiency (CVID), a frequent primary immunodeficiency disease, is characterized, by defects involving T and B cells. The Aiolos transcription factor plays an important role in the control of B cell differentiation and proliferation and is modulated through alternative splicing. In order to assess the role of Aiolos in this human pathology, we analyzed the Aiolos isoforms ...

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...

Common variable immunodeficiency (CVID) is an immunodeficiency disorder with a high incidence of gastrointestinal manifestations and an increased risk of gastric carcinoma and lymphoma. This review discusses the latest advancements into the immunological, clinical and diagnostic aspects of gastric malignancies in patients with CVID. The exact molecular pathways underlying the relationships betw...

Primary immunodeficiencies (PIDs) are characterized by impairment of one or more arms of the immune response, resulting in decreased defense, an increased number of infections, and, in certain cases, a higher incidence of autoimmune diseases and cancers.(1) Although PIDs are considered rare diseases, many of them are more common than are those currently diagnosed with the “heel prick” test. The...

Detailed studies of patients with so called cyclic neutropenia has revealed involvement of monocytes, lymphocytes, reticulocytes and platelets as well(2). Hence the term cyclic hematopoiesis is more appropriate. These parameters have not been mentioned in the. reported case. There is also no mention of whether the child had organomegaly. This is relevant because patients with cyclic neutropenia...

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...

Chronic infection with norovirus is emerging as a significant risk for patients with immunodeficiency - either primary or secondary to therapeutic immunosuppression. Patients with primary immunodeficiency present a range of pathological responses to norovirus infection. Asymptomatic infections occur and differentiating viral carriage or prolonged viral shedding after self-limiting infection fro...
