This study establishes a new range for serum IgG subclasses in healthy adults. The entire range of values from this group of control subjects was compared with values obtained from patients with bronchiectasis in order to determine the incidence of IgG subclass deficiency in this chronic lung disease. The two groups were of equivalent size and were matched for age and sex. All measurements were made by the same laboratory using consistent measurement techniques. Examination of the control range described here reveals that the lower limit for each subclass was consistently lower than those of control ranges published previously,6 9 12 16 which is probably due to our use of the entire range of measured values instead of 95th and 97th centile ranges or two standard deviations from the mean. French and Harrison have already shown that the frequency distributions of IgG subclasses in the serum of healthy adults is skewed, and that the use of the entire range or 95th centile range for each subclass is ...

Preclinical work has led to an increased understanding of the immunomodulatory mechanisms involved in the regulation of the antitumor response in a variety of tumor types. PD-1 (programmed death 1) appears to be a key checkpoint involved in immune suppression in the tumor microenvironment, even in diseases not previously thought to be sensitive to immune manipulation. More recently, the subsequent clinical development of PD-1-based therapy has resulted in a major breakthrough in the field of oncology. Pembrolizumab, a humanized highly selective IgG4 anti-PD-1 monoclonal antibody, was recently approved for the treatment of advanced melanoma based on promising early-phase clinical data ...

Our study has shown that Asian patients with a more severe clinical manifestation of pandemic influenza had a relatively lower overall level of IgG2 than patients with milder presentation. This was similar to the previously reported observation among Australian patients. While this key finding was consistent, there were some notable differences in the other findings of the two cohorts. In the Australian cohort, not only did the severe group have a lower overall IgG2 level but the majority of the individual patients (16/19; 84.2%) with severe infection also had IgG2 deficiency (6). Among our patients, only 1 out of 38 patients (2.6%) with severe infection had IgG2 deficiency. Even if the cutoff level of 2.4 g/liter used in the Australian study was adopted for our patients, only a minority of patients with severe infection (4/38; 10.5%) would fall into the deficient category. Also, the only patient in our severe group with deficiency did not have selective IgG2 deficiency but did have a broad ...

Loss-of-function mutations in DOCK8 are linked to hyper-IgE syndrome. Patients typically present with recurrent sinopulmonary infections, severe cutaneous viral infections, food allergies and elevated serum IgE. Although patients may present with a spectrum of disease-related symptoms, molecular mechanisms explaining phenotypic variability in patients are poorly defined. Here we characterized a novel compound heterozygous mutation in DOCK8 in a patient diagnosed with primary combined immunodeficiency which was not typical of classical DOCK8 deficiency. In contrast to previously identified mutations in DOCK8 which result in complete loss of function, the newly identified single nucleotide insertion results in expression of a truncated DOCK8 protein. Functional evaluation of the truncated DOCK8 protein revealed its hypomorphic function. In addition we found somatic reversion of DOCK8 predominantly in T cells. The combination of somatic reversion and hypomorphic DOCK8 function explains the milder and

Primary immunodeficiencies include a variety of disorders that render patients more susceptible to infections. If left untreated, these infections may be fatal. The disorders constitute a spectrum of more than 80 innate defects in the bodys immune system. Primary immunodeficiencies generally are considered to be relatively uncommon. There may be as many as 500,000 cases in the United States, of which about 50,000 cases are diagnosed each year. Common primary immunodeficiencies include disorders of humoral immunity (affecting B-cell differentiation or antibody production), T-cell defects and combined B- and T-cell defects, phagocytic disorders, and complement deficiencies. Major indications of these disorders include multiple infections despite aggressive treatment, infections with unusual or opportunistic organisms, failure to thrive or poor growth, and a positive family history. Early recognition and diagnosis can alter the course of primary immunodeficiencies significantly and have a positive effect
IgG subclass levels of sera from 26 patients with juvenile chronic arthritis (JCA) were determined by means of mouse monoclonal antibodies. Patients were divided into three groups according to clinical activity of the disease: active disease, partial remission, and remission. One hundred and sixty four age matched, healthy children served as controls. IgG subclass concentrations were log transformed, and a robust regression method was applied to obtain expected values for the different ages. We found a significant increase of IgG3 (p less than 0.0001), IgG1 (p less than 0.002), and IgG2 (p less than 0.035) in JCA sera, while IgG4 values did not differ significantly from those of controls. When patients were divided according to clinical activity significant increases of IgG2 and IgG4 were observed in the patients in partial remission. Our data suggest that differential increase of IgG subclasses during the courses of JCA may be of relevance to the pathogenesis of the disease. ...
Immunoglobulins are made by white blood cells known as B cells (B lymphocytes). Any disease that harms the development or function of B cells will, therefore, affect the production of immunoglobulin antibodies. T cells, another type of white blood cell, may also be involved in immunodeficiency disorders. About 70 percent of immunoglobulin deficiencies involve B lymphocytes and 20-30 percent involve T lymphocytes. Another 10 percent may involve both B and T lymphocytes. Many of the infections that occur in children with immunoglobulin deficiency syndromes are caused by bacterial organisms or microbes. Certain of these invasive organisms form capsules when they enter the body, a mechanism used to confuse the immune system. In a healthy body with an adequately functioning immune system, immunoglobulin antibodies bind to the capsule and overcome the bacterias defenses. Streptococci, meningococci, and Haemophilus influenzae , organisms that cause diseases such as otitis media , sinusitis , pneumonia ...
This study shows that two sympatric ethnic groups in Mali, the Fulani and the Dogon, exhibit differential frequencies in the expression of FcγRIIa R131H genotypes and allotypes. It furthermore, confirms and extends the previous findings regarding differences in anti-malarial responses between sympatric ethnic groups living in West Africa [12, 13]. The Fulani were less parasitized, had fewer parasite clones and had higher anti-malarial IgG subclass levels than the sympatric ethnic group, the Dogon. Fulani also showed a higher spleen rate as compared to Dogon. Interestingly, the Fulani showed significantly lower haemoglobin levels as compared to the Dogon, which was recently confirmed in both a longitudinal study and two cross sectional studies in the same study area (Dolo et al, personal communication).. The FcγRIIa R131H genotype results of this study contradict those from previous reports, where the R/R genotype has been associated with protection (reviewed by Braga [8]). Here it was revealed ...

The relatively lower susceptibility to malaria seen in the Fulani ethnic group in Africa, as compared to other sympatric ethnic groups, has been related to genetic regulation of the immune responses. This thesis aimed to describe important pathways related to the regulation of antibodies in the immune responses during a malaria infection. Our results suggest that the higher anti-malarial immune responses seen in the Fulani are not a general hyper-responsiveness in this group, but neither a malaria specific response. Fcγ receptors are important structures in the immune responses, and polymorphisms in these genes were associated with IgG subclass levels, P. falciparum parasitemia and haemoglobin levels, suggesting that these polymorphisms may be a contributing factor to the differential susceptibility to malaria. C-reactive protein levels rise immediately in response to inflammatory stimuli, and the -286 CRP polymorphism was indicated to influence parasite levels, suggesting a possible ...
Background: Childhood psoriasis has been reported to differ from that among adults. There are a limited number of studies on childhood psoriasis and none from the north-eastern part of India. A detailed clinical study will help to understand better the disease profile in children, thereby assisting in better diagnosis and treatment.

Using the SPARC definitions, rheumatologic conditions were diagnosed in 621,200 children and adolescent health care visits in 2012, of which 491,300 had a primary diagnosis of a rheumatologic condition. Only 2% of children and adolescents with any rheumatologic diagnoses were hospitalized (13,500), while less than 1% (4,200) with a primary diagnosis of a rheumatologic condition had a hospital discharge. The majority of children and adolescents with a rheumatologic condition diagnosis were seen in physicians offices. (Reference Table 7.1.1 PDF CSV; and Table 7.1.2 PDF CSV). Females were hospitalized with a rheumatologic condition at nearly three times the rate of males, both for any diagnoses and as a primary diagnosis. As children age, there is a higher incidence of rheumatologic conditions diagnosis.. Any diagnoses of a rheumatologic condition accounted for just under 3% of hospitalizations for any musculoskeletal condition diagnosis, and 0.2% of all hospitalizations for any health care ...
Abs to a number of polysaccharide Ags have several common attributes: CDR-H3 is implicated in binding to Ag (28, 29), its length is strictly maintained (20, 30), and its sequence is almost invariably characterized by the presence of hydrophilic tyrosine residues (21, 31, 32). Xu and Davis (9) showed that, in VH-restricted mice, CDR-H3 diversity was sufficient for the development of specific Ab responses to a variety of hapten and protein Ags but not for two bacterial polysaccharide Ags. The latter finding was attributed to the failure of the single VH gene in their mouse model to accommodate the polysaccharide-specific response, which suggested VH dependency. Work by Nakouzi and Casadevall (33) showed that, in addition to CDR-H3, CDR-H2 encoded amino acids critical for the generation of Abs specific for the polysaccharide galactoxylomannan. These studies highlighted the significant roles that both the VH, as a whole, and the CDR component of the VH, as a part, can play in the generation of ...

A very rare genetic disorder of the immune system can also be caused by mutations in this gene. This disease, called CEDS, stands for Caspase eight deficiency state. CEDS has features similar to ALPS, another genetic disease of apoptosis, with the addition of an immunodeficient phenotype. Thus, the clinical manifestations include splenomegaly and lymphadenopathy, in addition to recurrent sinopulmonary infections, recurrent mucocutaneous herpesvirus, persistent warts and molluscum contagiosum infections, and hypogammaglobulinemia. There is sometimes lymphocytic infiltrative disease in parenchymal organs, but autoimmunity is minimal and lymphoma has not been observed in the CEDS patients. CEDS is inherited in an autosomal recessive manner.[7]. The clinical phenotype of CEDS patients represented a paradox since caspase-8 was considered to be chiefly a proapoptotic protease, that was mainly involved in signal transduction from Tumor necrosis factor receptor family death receptors such as Fas. The ...

Definition of common variable immunodeficiency. Provided by Stedmans medical dictionary and Drugs.com. Includes medical terms and definitions.
Primary immunodeficiencies are inherited disorders of the immune system, often caused by the mutation of genes required for lymphocyte development and activation. Recently, several studies have identified gain-of-function mutations in the phosphoinositide 3-kinase (PI3K) genes PIK3CD (which encodes p110δ) and PIK3R1 (which encodes p85α) that cause a combined immunodeficiency syndrome, referred to as activated PI3Kδ syndrome (APDS; also known as p110δ-activating mutation causing senescent T cells, lymphadenopathy and immunodeficiency (PASLI)). Paradoxically, both loss-of-function and gain-of-function mutations that affect these genes lead to immunosuppression, albeit via different mechanisms. Here, we review the roles of PI3Kδ in adaptive immunity, describe the clinical manifestations and mechanisms of disease in APDS and highlight new insights into PI3Kδ gleaned from these patients, as well as implications of these findings for clinical therapy.. ...
Current Research and Scholarly Interests Studies in our lab are aimed at defining mechanisms in human immunity and disease. We are particularly interested the hypothesis that IgG repertoire diversity is a central driver of heterogeneity in human immune functioning and susceptibility to infectious diseases. Our work is defining how diversity that exists in the IgG Fc domain repertoire among people, which we define by serum IgG subclass and Fc glycoform distributions, impacts immune processes such as vaccine responses and susceptibility to antibody-dependent enhancement of dengue disease (Wang TT, Cell. 2015 and Wang TT, Science. 2017). IgG subclass and Fc glycoform distributions are key regulators of immunity because these determine the structure of Fc domains within immune complexes that form during vaccination or infection. Fc structure, in turn, determines the affinity of immune complexes for various Fc receptors on effector cells. Thus, we are studying how the Fc domain repertoire of an ...

We sought to compare Pneumovax®23 responses in adults with subnormal IgG subclass concentrations. We studied adults with normal total IgG, frequent/severe respiratory infection, and subnormal IgG1, IgG3, or IgG1 + IgG3 before and after Pneumovax®23. We defined response as serotype-specific IgG | 1.3 μg/mL and aggregate response as IgG | 1.3 μg/mL for ≥70% of all serotypes tested. We compared patients with and without serotype-specific responses and performed logistic regression on aggregate responses using: age; male sex; body mass index; autoimmune condition(s); atopy; other allergies; subnormal IgGSc immunophenotypes; IgA; and IgM. There were 59 patients (mean age 44 ± 13 (SD) years; 83.1% women). Median days between pre- and post-Pneumovax®23 testing was 33 (range 19-158). The median post-vaccination summated concentration of serotype-specific IgG was higher in patients with subnormal IgG1 than subnormal IgG3 (responders and non-responders). All subnormal IgG1 + IgG3 non-responders responded
