1. Serum immunoglobulin a deficiency and autoimmune comorbidities: a crossectional study in 281 patients with systemic lupus erythematosus
RESUMO OBJETIVO Estudar o perfil de doenças autoimunes associadas em uma série de pacientes com lúpus eritematoso sistêmico (LES) e verificar se tais associações estão ligadas à deficiência de imunoglobulina (Ig) A. MÉTODOS Foram estudados 281 pacientes com LES para os níveis de IgA por nefelometria. Níveis iguais ou menores que 0,05 g/dL for

2. Effects of Methionine Deficiency on the B Lymphocyte and Immunoglobulins of Cecal Tonsil in Cobb Broilers
ABSTRACT The present study was conducted on one-day-old broilers to investigate the effects of methionine deficiency on B lymphocytes and immunoglobulins (sIgA, IgA, IgG, IgM) in the cecal tonsil of Cobb broiler chicken. Methods including immunohistochemistry (IHC), western blot (WB), quantitative real-time reverse transcriptase-polymerase chain reaction (qR

3. THE PREVALENCE OF CELIAC DISEASE IN PATIENTS WITH IRON-DEFICIENCY ANEMIA IN CENTER AND SOUTH AREA OF IRAN
Contexto - A doença celíaca é uma enteropatia imunomediada, devido a uma sensibilidade permanente ao glúten em pessoas geneticamente suscetíveis. A anemia por deficiência de ferro é a anemia mais frequente em seres humanos e, além disso, é uma manifestação extra intestinal comum da doença celíaca. Objetivo - Investigar a correlação entre ní

4. Investigação de imunodeficiências primárias em pacientes com lúpus eritematoso sistêmico juvenil / Primary immunodeficiencies in juvenile systemic lupus erythematosus patients
Objetivos: Os objetivos deste estudo foram: avaliar a frequência de imunodeficiências primárias de anticorpos e Complemento em pacientes com lupus eritematoso sistêmico juvenil (LESJ); avaliar possíveis associações entre a presença de imunodeficiência primária (IDP) e dados demográficos, ocorrência de infecções, manifestações clínicas, ativi

5. Evaluation of the immune humoral response of Brazilian patients with Rubinstein-Taybi syndrome
Rubinstein-Taybi syndrome (RTS) is a rare developmental disorder characterized by craniofacial dysmorphisms, broad thumbs and toes, mental and growth deficiency, and recurrent respiratory infections. RTS has been associated with CREBBP gene mutations, but EP300 gene mutations have recently been reported in 6 individuals. In the present study, the humoral imm

6. Aspectos clínico-laboratoriais na evolução de pacientes com deficiência de imunoglobulina A diagnosticados na infância e de seus familiares / Clinical and laboratorial features from patients with IgA deficiency diagnosed in childhood and from their relatives
A deficiência de imunoglobulina A (DIgA) é a imunodeficiência primária mais comum com prevalência de 1: 223 a 1:1000 em estudos epidemiológcos, sendo menos freqüente em populações asiáticas. As manifestações clínicas variam desde indivíduos assintomáticos até aqueles com manifestações atópicas, auto-imunes ou infecciosas. Entre estas últi

7. Prevalence of celiac disease in Brazilian children of short stature
The aim of the present study was to determine the prevalence of celiac disease in children of short stature and to assess whether some of the routine laboratory examinations performed to determine the cause of short stature could suggest the presence of celiac disease. A total of 106 children of short stature and no gastrointestinal symptoms were studied. An

8. Selective IgA deficiency and spondyloarthropathy: a distinct disease?
A woman with selective IgA deficiency and severe ankylosing spondylitis (AS), complicated by intractable peripheral arthritis, is described. Three previous cases of selective IgA deficiency and AS have been reported, all of whom had severe AS. It is suggested that selective IgA deficiency is a poor prognostic factor in AS and therefore warrants further inves

9. Increased Prevalence of Immunoglobulin A Deficiency in Patients with the Chromosome 22q11.2 Deletion Syndrome (DiGeorge Syndrome/Velocardiofacial Syndrome)
We wished to determine the prevalence of immunoglobulin A (IgA) deficiency in patients with the chromosome 22q11.2 deletion syndrome. A total of 32 patients with the chromosome 22q11.2 deletion were examined for IgA deficiency. We report a 13% (n = 4) prevalence of IgA deficiency in patients with this syndrome. The odds ratio of IgA deficiency in this popula

10. Selective IgA deficiency associated with glomerulonephritis and oligoarthritis.
A 59 year old woman with selective IgA deficiency associated with oligoarthritis and glomerulonephritis is described. She was seropositive for rheumatoid factor and renal histological examination showed a focal glomerulonephritis. High titre rheumatoid factor and a focal glomerulonephritis were also present in the only other well documented report of selecti

11. Individuals with IgA deficiency and common variable immunodeficiency share polymorphisms of major histocompatibility complex class III genes.
IgA deficiency and common variable immunodeficiency are heritable disorders that can occur within the same family. Both immunodeficiencies are characterized by arrests in B-cell differentiation that vary in the extent of the immunoglobulin isotypes involved. A high frequency of major histocompatibility complex supratypes associated with a null allele of the

12. Immunoglobulin A (IgA) Deficiency and Alternative Celiac Disease-Associated Antibodies in Sera Submitted to a Reference Laboratory for Endomysial IgA Testing
Immunoglobulin A (IgA) deficiency occurs more frequently in patients with celiac disease (CD) than in the general population and can lead to false-negative results in the best serologic test for CD, endomysial IgA (EMA). To evaluate the impact of IgA deficiency on serologic detection of CD in a reference laboratory setting, IgA levels were measured in 510 co
