Common variants at PVT1, ATG13–AMBRA1, AHI1 and CLEC16A are associated with selective IgA deficiency
Screening of blood donors for IgA deficiency: a study of the donor population of south-west England.
Altogether 29 745 English blood donors were screened for IgA deficiency by double diffusion analysis; 57 had apparent absence of IgA, a frequency of 1:522. Further examination by the more sensitive haemagglutination inhibition assay revealed 34 samples having no detectable IgA, a frequency of 1:875. All donors negative by double diffusion analysis were tested for the presence of antibodies to I...
BACKGROUND Immunoglobulin (Ig) A deficiency is a primary immunodeficiency in which autoimmunity is frequently observed. Thirty to fifty percent of patients with spontaneous chronic urticaria have autoantibodies that are able to cross-link FcεRI on mast cells and basophils. METHODS We investigated whether spontaneous chronic urticaria in patients with IgA deficiency meets the criteria for auto...
Anderson-Fabry disease is a rare inherited X-linked lysosomal storage disease caused by deficiency of the enzyme alpha-galactosidase A. Hereby we report a 39 year old male that presented with proteinuria and edema. Histopathologic, immunofluorescence and ultrastractural examination of renal tissue were in favor of Fabry disease in associate with IgA nephropathy. Fabry's disease associated ...
Background: The airway surfaces are one of the most common ways of entry of infectious agents. Oral cavity associated lymphoid tissues are inductive site of humoral immune responses in inflammatory and infectious disorders of the upper respiratory tract. These lymphoid tissues play important roles in the induction of salivary IgA. The impact of upper respiratory tract diseases on salivary IgA p...
epidemiological studies have shown wide geographical and racial variation in the prevalence and patterns of immunodeficiency disorders. to determine the frequency of primary immunodeficiencies (pid) in iran, the iranian primary immunodeficiencies registry (ipidr) was organized in 1999. the diagnosis of immunodeficiency in our patients was based on standard criteria. the patient’s data were extr...
the main clinical presentation of patients with primary antibody deficiency (pad) incorporates upper respiratory tract infections comprising otitis media, sinusitis and pneumonia. this study was designed to investigate clinical and paraclinical otological complications in major types of pad. a cross sectional study was conducted on 55 pad patients with diagnosis of selective iga ...
BACKGROUND Experimental studies showed that 25-hydroxy-vitamin D [25(OH)D] deficiency (defined as 25-hydroxy-vitamin D < 15 ng/ml) has been associated with CKD progression. Patients with IgA nephropathy have an exceptionally high rate of severe 25(OH)D deficiency; however, it is not known whether this deficiency is a risk factor for progression of IgA nephropathy. We conducted this study to inv...
