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...

primary antibody deficiencies (pad) are a group of immune system disorders, associated with decreased levels of secretory and protective immunoglobulins. because of the important role of immunoglobulins in the protection  of oral cavity, patients with pads  are more susceptible to dental caries or oral manifestations. this study was performed  to investigate the oral and dental manifestations o...

Background: Selective antibody deficiency with normal immunoglobulins (SADNI) may be identified as part of distinct primary or secondary immunodeficiency disorders. The clinical manifestations include recurrent, often severe or prolonged, upper or lower respiratory tract infections. Objectives: To evaluate SADNI in patients with recurrent sinopulmonary infections and its relation to IgG subclas...

BACKGROUND Primary antibody deficiencies (PADs) are heterogeneous group of disorders, characterized by hypogammaglobulinemia and increased susceptibility to recurrent infections. To evaluate the diagnostic delay in Iranian PADs in association with their infections, we scored such manifestations to find an association between such delay and the scoring system. METHODS Forty-eight patients with...
