"IgG deficiency"

Recurrent C. difficile in a Patient with IgG Deficiency IgG deficiency can predispose to recurrent pyogenic infections. The association of IgG deficiency with Clostridium difficile infection has been infrequently reported in the literature. We present a case of a middle-age woman with multiple hospitalizations for recurrent C. difficile in a short span of time which prompted consideration evidence of benefit. 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.

management of the underlying condition will in many cases reverse hypogammaglobulinaemia. However in some cases, it may persist and be complicated by recurrent or severe bacterial infections. Approximately 15 percent of patients who have received a solid organ (heart, lung, kidney) transplant experience secondary hypogammaglobulinaemia with severe IgG deficiency (<400mg/dL) during the first year after

%) of 38 participants with neurocognitive outcomes scored lower than one SD on at least one neurocognitive outcome, three (7%) reported chronic medical conditions (spasmophilia, spastic diplegia, and IgG deficiency), and three (7%) were diagnosed with attention-deficit hyperactivity disorder (of whom two scored lower on attention). Of ten (23%) participants with lower neurocognitive score(s), a chronic

However, no significant association was found between Ig concentrations, particularly serum IgG deficiency and its subclasses, with the frequency and risk of exacerbations during 12 months of longitudinal follow-up. Caution is warranted in the use of immunoglobulin therapy in the treatment of COPD patients. An independent ethics committee approved the study (Ethics Committee of Military Hospital 103

He received treatment with nirmatrelvir und ritonavir and because of diagnosed IgG deficiency additionally a single dose of 20 g IVIG. During the IVIG infusion, the patient acutely developed tachycardia, hypotension, fever, chills, and hypoxemic respiratory failure due

The common variable immunodeficiency IgM repertoire narrowly recognizes erythrocyte and platelet glycans. Autoantibody-mediated cytopenias (AICs) regularly occur in profoundly IgG-deficient common variable immunodeficiency (CVID) patients. The isotypes, antigenic targets, and origin(s) of their disease-causing autoantibodies are unclear. To determine reactivity, clonality and provenance of AIC

and mice, immunoglobulin G (IgG) antibodies are the most potent anti-microbial antibody isotype due to their long half-life, their ability to penetrate almost all tissues and due to their ability to trigger a wide variety of effector functions. Of note, individuals suffering from IgG deficiency frequently produce self-reactive antibodies, suggesting that a normal serum IgG level also may contribute

Serum Immunoglobulin G Levels Are Associated with Risk for Exacerbations: An Analysis of SPIROMICS. Serum Immunoglobulin G (IgG) deficiency is associated with morbidity in chronic obstructive pulmonary disease (COPD) but it is unclear whether concentrations in the lower end of the normal range still confer risk. To determine if levels above traditional cutoffs for serum IgG deficiency

in Boston with IgA and/or IgG deficiency (group A) or normal IgA and IgG (group B) were queried between January 1, 2016 and December 31, 2022. Other immunodeficiencies were excluded. The groups were analyzed for prevalence of CRS based on ICD-10 codes. The groups were matched based on demographics and comorbidities. Patients with CRS were analyzed for ≥3 acute rhinosinusitis (ARS) episodes, mean lifetime ARS episodes, and mean ARS episodes per year (all with or without antibiotic treatment). Additional analyses included need for functional endoscopic sinus surgery (FESS) and mean lifetime FESS procedures based on CPT codes. A logistic regression analysis was then performed over the same parameters. A total of 346 patients had IgA and/or IgG deficiency (group A), and 11,438 patients had normal IgA

a total of 15 adults: normal controls (n = 8), patients with CVID on IVIG replacement (n = 2), patients on IVIG replacement for recurrent infections who did not meet diagnostic criteria for CVID, considered IgG deficiency (n = 2), and patients without immunodeficiency on high-dose IVIG for other diagnosis (n = 3). We measured P23 serotype-specific IgG before and 4 weeks after P23 and ELISPOT ASCs before

exacerbation (multivariable hazard ratio 1.03 per 200 ng/ml increase (95% confidence interval (CI) 1.00-1.06), p = 0.048), whereas ficolin-2 and IgG deficiency were not associated. The risk was most pronounced in patients with high MBL concentrations, IgG deficiency and 14 days of glucocorticoid treatment pointing towards an interactive effect of MBL and IgG deficiency in the presence of prolonged glucocorticoid treatment duration [Relative excess risk due to interaction 2.13 (95% CI - 0.41-4.66, p = 0.10)]. IgG concentrations were significantly lower in patients with frequent re-exacerbations (IgG, 7.81 g/L vs. 9.53 g/L, p = 0.03). MBL modified the short-term exacerbation risk after a recent acute exacerbation of COPD, particularly in the setting of concurrent IgG deficiency and recent prolonged

Initially no pathogen could be detected, but after 4 days Cryptococcus neoformans was found in the patient's blood cultures leading to the diagnosis of cryptococcal meningoencephalitis. After antimycotic therapy, her symptoms improved and the patient was discharged. MS patients on immunomodulatory  therapy are at constant risk for opportunistic infections. Cephalgia

As 41% BE were idiopathic, in 11% the disorder was postinfectious and others were associated to rheumatic disease, Alpha-1-antitrypsin deficiency, IgG deficiency and Kartagener syndrome.

) guidelines, and bronchiectasis was ruled out by a CT chest scan. Two men (aged 28 and 60) presented with pollen allergies, chronic rhinosinusitis, and IgG deficiency (7.8 and 7.6 g/L, respectively). Both patients underwent surgery for nasal polyposis but relapsed with acute sinusitis and severe asthma exacerbations requiring treatment with oral corticosteroids and antibiotics. The immunoglobulin replacement therapy (IRT) partially relieved the asthma by reducing the number of exacerbations. A 55-year-old woman presented with nonallergic, corticosteroid-dependent asthma (20 mg/day prednisone) and IgG deficiency (5.72 g/L). IRT improved asthma control (fall in the Asthma Control Questionnaire (ACQ)-7 score from 3.5 to 1.7) and enabled withdrawal of the corticosteroids. In a 47-year-old woman
