IgG Deficiency

06/01/2011 - "This study aimed to determine whether nonprotective, convalescent pneumococcal serotype-specific immunoglobulin G (IgG) concentrations in children with invasive pneumococcal disease (IPD) might be associated with an underlying IgG deficiency. "
06/01/2011 - "Although 11% of children with IPD had IgG deficiency, total serum IgG concentrations were reassuringly only marginally below the reference range and were within the normal range in those who were retested, suggesting a transient deficiency rather than a serious underlying primary immunodeficiency."
06/01/2011 - "Three children with IgG deficiency who were retested 3 to 5 months later had normal serum IgG concentrations. "
06/01/2011 - "Nineteen of 172 children (11.0%) with sufficient serum had IgG deficiency although serum IgG concentrations were only marginally below the lower limit for age and all 19 had IgG concentrations >2.0 g/L. "
06/01/2011 - "IgG deficiency was defined as total serum IgG ≥2 standard deviations below the mean for age. "

02/01/2012 - "Only one of four common variable immunodeficient (CVID) patient sera failed to kill SV3, despite profound IgM and IgG deficiency for all; however, killing of SV3 and SV1 was restored with therapeutic intravenous immunoglobulin therapy. "
11/01/2003 - "All of the patients had significant IgG deficiency and most had IgA deficiency, but only one-half had elevated IgM levels. "
12/01/2015 - "A meta-analysis of the proportion of any combination of common variable immunodeficiency, IgG deficiency, IgA deficiency, and IgM deficiency in patients with CRS was performed by using logit transformation of the prevalence. "
01/01/2001 - "Of those patients with Ig deficiencies, three of eight had isolated IgG deficiency, two of eight had combined IgG and IgA deficiency, three of eight had combined IgG and IgM deficiency. "
01/01/1987 - "Intravenous immunoglobulin has also been used for some patients with transient hypogammaglobulinaemia, isolated IgG deficiency, isolated IgA deficiency and isolated IgM deficiency. "

07/01/2007 - "The coexistence of HIES, IgA and IgG deficiencies has, to our knowledge, not been reported previously in the literature."
07/01/2007 - "IgA and IgG deficiencies were also identified, which are rare associations of this syndrome and complicated the patient's treatment. "
07/01/2007 - "A young man with hyperimmunoglobulin-E syndrome and IgA and IgG deficiencies."
03/29/2003 - "The IgG deficiency was constant and IgA deficieny encountered in 12 patients. "
04/01/1990 - "No IgA was detected in the stool of a dysgammaglobulimic patient, who had both serum IgA and IgG deficiencies."

06/01/1999 - "Total IgE was independent of the type of IgG deficiency, except for usual common variable immunodeficiency in which it remained < 10 IU/mL. In adults with symptomatic IgG deficiency, the prevalence of immediate hypersensitivity and its modulation by age and smoking are similar to the referred, non-IgG deficient population; however, total IgE may be lower in the former than in the latter. "
06/27/1981 - "There was no difference between patients and controls in prevalence of atopy; positive results of prick tests to common antigens; eosinophil counts; yeast opsonisation defect; C2 deficiency; IgG, IgA, IgM, and IgE concentrations; or IgE antibody to dermatophagoides, timothy-grass pollen, and cat fur. "

06/27/1981 - "There was no difference between patients and controls in prevalence of atopy; positive results of prick tests to common antigens; eosinophil counts; yeast opsonisation defect; C2 deficiency; IgG, IgA, IgM, and IgE concentrations; or IgE antibody to dermatophagoides, timothy-grass pollen, and cat fur. "

12/01/2006 - "Intravenous (IV) and subcutaneous (SC) immunoglobulin (Ig) administration is a safe and an efficacious treatment in patients with IgG deficiency. "
01/01/2015 - "Our case report suggests that the patients who have underlying IgG deficiency may benefit from immunoglobulin, as this can significantly reduce the incidence of recurrent infections and hence save the healthcare costs. "
10/01/1989 - "Five patients had a combined quantitative immunoglobulin and IgG subclass deficiency and one patient had an isolated IgG deficiency. "
05/01/2007 - "Intravenous Human immunoglobulin (IVIg) administration is a safe and efficacious treatment in IgG deficiency and auto-immune diseases. "
12/01/1994 - "Serum immunoglobulins were disturbed in 22/25 patients investigated (IgG deficiency, IgA deficiency, IgG2 and IgG4 deficiency) and T cell defects were found in 23/24 patients tested. "

12/01/2006 - "Our data indicated that IVIG induction prevented severe IgG deficiency in the early posttransplant period but had no impact on severe infectious complications. "
11/10/1996 - "Intravenous immunoglobulins (IVIG) are now used to treat various diseases, including autoimmune diseases, systemic inflammatory diseases, allografts and for replacement therapy in the case of IgG deficiency. "
05/01/2007 - "Intravenous Human immunoglobulin (IVIg) administration is a safe and efficacious treatment in IgG deficiency and auto-immune diseases. "
12/01/2006 - "IVIG induction therapy resulted in upregulation of serum IgG and IgA levels within the first 20 days posttransplant (P = .001, IgG; P = .04, IgA), so that a significant IgG deficiency was found only in non-IVIG patients (day 10: IgG <6 g/L: 7/25 (28%) non-IVIG versus 0/25 IVIG patients; P = .005). "

01/01/1990 - "Selective IgG deficiency with a transcriptional disorder of the gamma switching region gene and the IL-4 gene."

01/01/2009 - "Down-Syndrome associated with MBL-deficiency, IgG-deficiency, vasculitis and mutated prothrombin."
01/01/2009 - "We report a 30 year-old female with Down-syndrome associated with MBL-deficiency with the genotype LXA/HYD, IgG-deficiency, recurrent uro-genital infections, cutaneous vasculitis, G20.210A prothrombin mutation, deep venous thrombosis, and pulmonary embolism. "

01/01/2001 - "Middle ear secretion contained less SIgA and lysozyme, blood contained more amount of IgA and IgM and less of IgG. Deficiency of general and local defense antiinfectious mechanisms shows significance of immune and nonspecific resistance in transformation of ear inflammation into chronic phase and development of complications. "

11/10/1996 - "Intravenous immunoglobulins (IVIG) are now used to treat various diseases, including autoimmune diseases, systemic inflammatory diseases, allografts and for replacement therapy in the case of IgG deficiency. "

11/01/2008 - "Relevant comorbid factors included prior Caldwell-Luc or maxillofacial surgery (16/42), cystic fibrosis (11/42), asthma (11/42), and IgG deficiency (3/42). "
