Agammaglobulinemia: An immunologic deficiency state characterized by an extremely low level of generally all classes of gamma-globulin in the blood.Genetic Diseases, X-Linked: Genetic diseases that are linked to gene mutations on the X CHROMOSOME in humans (X CHROMOSOME, HUMAN) or the X CHROMOSOME in other species. Included here are animal models of human X-linked diseases.X Chromosome: The female sex chromosome, being the differential sex chromosome carried by half the male gametes and all female gametes in human and other male-heterogametic species.Protein-Tyrosine Kinases: Protein kinases that catalyze the PHOSPHORYLATION of TYROSINE residues in proteins with ATP or other nucleotides as phosphate donors.B-Lymphocytes: Lymphoid cells concerned with humoral immunity. They are short-lived cells resembling bursa-derived lymphocytes of birds in their production of immunoglobulin upon appropriate stimulation.Genetic Linkage: The co-inheritance of two or more non-allelic GENES due to their being located more or less closely on the same CHROMOSOME.Immunologic Deficiency Syndromes: Syndromes in which there is a deficiency or defect in the mechanisms of immunity, either cellular or humoral.Immunoglobulin delta-Chains: The class of heavy chains found in IMMUNOGLOBULIN D. They have a molecular weight of approximately 64 kDa and they contain about 500 amino acid residues arranged in four domains and an oligosaccharide component covalently bound to the Fc fragment constant region.IgG Deficiency: A dysgammaglobulinemia characterized by a deficiency of IMMUNOGLOBULIN G.Ecthyma: An ulcerative pyoderma usually caused by group A beta-hemolytic streptococcal infection at the site of minor trauma. (Dorland, 27th ed)Campylobacter lari: A species of thermophilic CAMPYLOBACTER found in healthy seagulls and causing ENTERITIS in humans.Receptors, Antigen, B-Cell: IMMUNOGLOBULINS on the surface of B-LYMPHOCYTES. Their MESSENGER RNA contains an EXON with a membrane spanning sequence, producing immunoglobulins in the form of type I transmembrane proteins as opposed to secreted immunoglobulins (ANTIBODIES) which do not contain the membrane spanning segment.Helicobacter: A genus of gram-negative, spiral-shaped bacteria that has been isolated from the intestinal tract of mammals, including humans. It has been associated with PEPTIC ULCER.Immunoglobulins, Intravenous: Immunoglobulin preparations used in intravenous infusion, containing primarily IMMUNOGLOBULIN G. They are used to treat a variety of diseases associated with decreased or abnormal immunoglobulin levels including pediatric AIDS; primary HYPERGAMMAGLOBULINEMIA; SCID; CYTOMEGALOVIRUS infections in transplant recipients, LYMPHOCYTIC LEUKEMIA, CHRONIC; Kawasaki syndrome, infection in neonates, and IDIOPATHIC THROMBOCYTOPENIC PURPURA.Chromosomes, Human, X: The human female sex chromosome, being the differential sex chromosome carried by half the male gametes and all female gametes in humans.Dosage Compensation, Genetic: Genetic mechanisms that allow GENES to be expressed at a similar level irrespective of their GENE DOSAGE. This term is usually used in discussing genes that lie on the SEX CHROMOSOMES. Because the sex chromosomes are only partially homologous, there is a different copy number, i.e., dosage, of these genes in males vs. females.

Identification of a subpopulation of lymphocytes in human peripheral blood cytotoxic to autologous fibroblasts. (1/604)

A naturally occurring subpopulation of human peripheral blood lymphocytes is cytotoxic to autologous and/or allogeneic fibroblasts. The autocytotoxic lymphocytes have a receptor for the third component of complement and for aggregated gamma globulin, do not form rosettes with sheep red blood cells, and are not removed by passage through nylon. The autocytotoxic subpopulation is not present in the thymus and tonsils of normal children or in the peripheral blood of individuals with X-linked agammaglobulinemia. Fibroblast absorption experiments demonstrate that the autocytotoxic cells are "sensitized" to antigens expressed on allogeneic fibroblasts in addition to the antigens expressed on autologous cells. Some normal individuals have a second subpopulation of lymphocytes that may "regulate" the autocytotoxic cells. The relevance of these observations to the murine autocytotoxic cells is discussed.  (+info)

Induction of human immunoglobulin synthesis and secretion in somatic cell hybrids of mouse myeloma and human B lymphocytes from patients with agammaglobulinemia. (2/604)

Somatic cell hybrid clones were isolated from the fusion of RPC 5,4 mouse myeloma cells and B lymphocytes from three patients with agammaglobulinemia. One patient had X-linked agammaglobulinemia; the remaining two patients had common varied agammaglobulinemia. All three patients had B lymphocytes which fail to secrete immunoglobulin. The hybrid nature of the clones was established by examination of metaphase chromosome spreads. Most of the clones from all three patients expressed surface immunoglobulin of mouse and human parental origin. Clones from two of the patients had fewer cells with surface Ig than hybrids from normal persons, while clones from the third patient had large numbers of surface Ig fluorescent cells. Most of the clones from all three patients synthesized and secreted human and mouse immunoglobulin. As determined by sodium dodecyl sulfate acrylamide gel electrophoresis of radioactively labeled proteins, clones from each of the patients produced human gamma, alpha, and mu-heavy chains. These studies demonstrate the presence of functional structural genes coding for human immunoglobulin heavy chains in B lymphocytes of patients with agammaglobulinemia. Further, they represent induction in the somatic cell hybrids of a gene product not expressed in the parental B lymphocytes.  (+info)

Functions of Bruton's tyrosine kinase in mast and B cells. (3/604)

Bruton's tyrosine kinase (Btk) plays crucial roles in B cell differentiation as well as mast cell activation through the high-affinity IgE receptor (FcepsilonRI). Defects in the btk gene lead to agammaglobulinemia (XLA) in humans and X-linked immunodeficiency (xid) in mice. Mast cells from xid and btk null mice exhibit mild defects in degranulation and severe impairments in the production of proinflammatory cytokines upon FcepsilonRI cross-linking. Recent studies demonstrated the role of Btk in a sustained increase in intracellular calcium concentrations in response to antigen receptor stimulation. Btk is also involved in the activation of stress-activated protein kinases, JNK/SAPK1/2, and thereby regulates c-Jun and other transcription factors that are important in cytokine gene activation. Regulation of the JNK/SAPK activation pathway by Btk may be related to the proapoptotic function of Btk in the programmed cell death in these hematopoietic cells.  (+info)

Comparative genomics and host resistance against infectious diseases. (4/604)

The large size and complexity of the human genome have limited the identification and functional characterization of components of the innate immune system that play a critical role in front-line defense against invading microorganisms. However, advances in genome analysis (including the development of comprehensive sets of informative genetic markers, improved physical mapping methods, and novel techniques for transcript identification) have reduced the obstacles to discovery of novel host resistance genes. Study of the genomic organization and content of widely divergent vertebrate species has shown a remarkable degree of evolutionary conservation and enables meaningful cross-species comparison and analysis of newly discovered genes. Application of comparative genomics to host resistance will rapidly expand our understanding of human immune defense by facilitating the translation of knowledge acquired through the study of model organisms. We review the rationale and resources for comparative genomic analysis and describe three examples of host resistance genes successfully identified by this approach.  (+info)

IgM heavy chain complementarity-determining region 3 diversity is constrained by genetic and somatic mechanisms until two months after birth. (5/604)

Due to the greater range of lengths available to the third complementarity determining region of the heavy chain (HCDR3), the Ab repertoire of normal adults includes larger Ag binding site structures than those seen in first and second trimester fetal tissues. Transition to a steady state range of HCDR3 lengths is not complete until the infant reaches 2 mo of age. Fetal constraints on length begin with a genetic predilection for use of short DH (D7-27 or DQ52) gene segments and against use of long DH (e.g., D3 or DXP) and JH (JH6) gene segments in both fetal liver and fetal bone marrow. Further control of length is achieved through DH-specific limitations in N addition, with D7-27 DJ joins including extensive N addition and D3-containing DJ joins showing a paucity of N addition. DH-specific constraints on N addition are no longer apparent in adult bone marrow. Superimposed upon these genetic mechanisms to control length is a process of somatic selection that appears to ensure expression of a restricted range of HCDR3 lengths in both fetus and adult. B cells that express Abs of an "inappropriate" length appear to be eliminated when they first display IgM on their cell surface. Control of N addition appears aberrant in X-linked agammaglobulinemia, which may exacerbate the block in B cell development seen in this disease. Restriction of the fetal repertoire appears to be an active process, forcing limits on the diversity, and hence range of Ab specificities, available to the young.  (+info)

Early arrest in B cell development in transgenic mice that express the E41K Bruton's tyrosine kinase mutant under the control of the CD19 promoter region. (6/604)

Bruton's tyrosine kinase (Btk) is a nonreceptor protein kinase that is defective in X-linked agammaglobulinemia in humans and in X-linked immunodeficiency in mice. To study the effect of Btk activation in early B cell development in vivo, we have created transgenic mouse strains expressing Btk under the control of the human CD19 promoter region. The transgenic expression of wild-type human Btk corrected all X-linked immunodeficiency features in mice carrying a targeted disruption of the Btk gene. In contrast, expression of an activated form of Btk, the E41K mutant, resulted in an almost complete arrest of B cell development in the immature IgM+IgD- B cell stage in the bone marrow, irrespective of the presence of the endogenous intact Btk gene. Immature B cells were arrested at the progression from IgMlow into IgMhigh cells, which reflects the first immune tolerance checkpoint at which autoreactive B cells become susceptible to apoptosis. As the constitutive activation of Btk is likely to mimic B cell receptor occupancy by autoantigens in the bone marrow, our findings are consistent with a role for Btk as a mediator of B cell receptor-induced apoptotic signals in the immature B cell stage. Whereas the peripheral mature B cell pool was reduced to <1% of the normal size, significant numbers of IgM-secreting plasma cells were present in the spleen. Serum IgM levels were substantial and increased with age, but specific Ab responses in vivo were lacking. We conclude that the residual peripheral B cells were efficiently driven into IgM+ plasma cell differentiation, apparently without functional selection.  (+info)

In vivo modulation of cytokine synthesis by intravenous immunoglobulin. (7/604)

We examined the effects of intravenous immunoglobulin (IVIG) on cytokine regulation in vivo using samples taken before and after replacement-dose (200-400 mg/kg) IVIG in a group of patients with common variable immunodeficiency (CVID) and X-linked agammaglobulinaemia (XLA). The intracellular cytokine content of CD4+ and CD8+ lymphocytes, and their CD28+/- subsets, were measured following in vitro activation with phorbol myristate acetate (PMA) and ionomycin. The cytokines IL-2, interferon-gamma (IFN-gamma) and tumour necrosis factor-alpha (TNF-alpha), and the early activation marker CD69, were assessed by four-colour flow cytometry of whole blood cultures taken before and after IVIG infusion. There was a significant increase in IL-2 expression in CD4+ (and CD4+28-) cells and an increase in TNF-alpha expression in CD8+28- cells following IVIG in CVID, but not in XLA patients. IFN-gamma and CD69 expression were not affected by IVIG infusion. This increase in TNF-alpha and IL-2, combined with unchanged IFN-gamma expression, is evidence against the putative 'anti-inflammatory' role of IVIG, and may explain the failure of resolution of granulomata in CVID patients treated with IVIG alone.  (+info)

CD95 expression and function on lymphocyte subpopulations in common variable immunodeficiency (CVID); related to increased apoptosis. (8/604)

Apoptosis is now recognized as a central process of development and disease, and it has been proposed as one of the mechanisms that may account for the lymphopenia seen in some diseases. In this study we measured spontaneous apoptosis and CD95 expression on different cell subpopulations from CVID patients, using flow cytometric techniques. We divided our patients into two groups according to their CD4+ and CD4+CD45RA+ cell counts. Our results clearly show increased spontaneous apoptosis and CD95 expression on the CD4+ and CD4+CD45RA+ subsets from lymphopenic CVID patients compared with normal subjects and disease controls. Interestingly, our lymphopenic CVID patients presented a profound reduction in absolute counts, mainly affecting the CD4+CD45RA+ subpopulation. We also found a statistically significant direct correlation between absolute numbers of CD4+CD45RA+ T cells and spontaneous apoptosis on the same subset in CVID patients, but attempts to induce CD95-mediated apoptosis were unsuccessful despite increased CD95 expression on CD4+ T cells. These findings suggest that apoptosis could be one of the mechanisms implicated in the significant lymphopenia present in these patients.  (+info)

X-linked agammaglobulinemia, also known as Bruton agammaglobulinemia, is caused by a mutation in a gene found in the X chromosome. This mutation affects the ability of the body to fight infections. Because it is an X-linked mutation, XLA mostly affects boys.. Symptoms often start around six months in age. As protective antibodies from the infants mother wear off, patients with XLA are unable to produce enough B cells, compromising the bodys ability to fight infection. In rare cases, symptoms might not occur until the patient is a teenager.. XLA is extremely rare, occurring in only one in 200,000 newborns. Children with XLA might cope well with short-term viral infections but are susceptible to chronic viral infections such as hepatitis and polio. Common bacterial infections in XLA patients include ear infections, pink eye, pneumonia, sinus infections and other infections causing diarrhea.. Regular immune globulin treatment can offer XLA patients the antibodies crucial to their health.. ...

X-linked agammaglobulinemia (XLA) is a rare genetic disorder discovered in 1952 that affects the bodys ability to fight infection. As the form of agammaglobulinemia that is X-linked, it is much more common in males. In people with XLA, the white blood cell formation process does not generate mature B cells, which manifests as a complete or near-complete lack of proteins called gamma globulins, including antibodies, in their bloodstream. B cells are part of the immune system and normally manufacture antibodies (also called immunoglobulins), which defend the body from infections by sustaining a humoral immunity response. Patients with untreated XLA are prone to develop serious and even fatal infections. A mutation occurs at the Brutons tyrosine kinase (Btk) gene that leads to a severe block in B cell development (at the pre-B cell to immature B cell stage) and a reduced immunoglobulin production in the serum. Btk is particularly responsible for mediating B cell development and maturation through ...
X-linked agammaglobulinemia is a rare genetic disease. It causes a weakened immune system. It is also known as Brutons agammaglobulinemia. X-linked means that the gene that causes this disease is located on the X chromosome. It mainly affects boys, because they have only have one X chromosome. A child with this disease cant make antibodies that are part of gamma globulins in blood plasma. Antibodies are the bodys main defense against germs like bacteria and viruses. So a child with this disease cant fight off infections caused by bacteria and by some viruses. Boys with this disease are more likely to get infections in the middle ear, sinuses, and lungs. The infections can also involve the bloodstream or internal organs. Most children with this disease who are treated early can lead normal, active lives. ...
Intestinal absorption was investigated in six patients with a diagnosis of primary hypogammaglobulinemia. Malabsorption was found in four patients. Low serum vitamin E levels, decreased D-xylose absorption, and increased 5-hydroxyindoleacetic acid excretion in the urine correlated with malabsorption with minor exceptions. Five patients were subjected to jejunal biopsies, and nodular lymphoid hyperplasia was found on at least one examination in each of these patients. In addition, partial to complete mucosal atrophy characterized biopsy specimens from four patients and correlated with steatorrhea with one exception. Although gastric achlorhydria (two patients), minimal to moderate pancreatic insufficiency (two patients), significant intestinal intraluminal bacterial overgrowth (three patients), and Giardia lamblia (five patients) were found, the evidence suggests that the most significant cause of malabsorption in these hypogammaglobulinemic patients is an intestinal mucosal lesion. Reversibility ...
X-linked agammaglobulinemia (XLA) is a primary immunodeficiency disease caused by mutations in the gene coding for Brutons tyrosine kinase (BTK). Deficiency of BTK leads to a developmental block in B cell differentiation; hence, the patients essentially lack antibody-producing plasma cells and are susceptible to various infections. A substantial portion of the mutations in BTK results in splicing defects, consequently preventing the formation of protein-coding mRNA. Antisense oligonucleotides (ASOs) are therapeutic compounds that have the ability to modulate pre-mRNA splicing and alter gene expression. The potential of ASOs has been exploited for a few severe diseases, both in pre-clinical and clinical studies. Recently, advances have also been made in using ASOs as a personalized therapy for XLA. Splice-correction of BTK has been shown to be feasible for different mutations in vitro, and a recent proof-of-concept study demonstrated the feasibility of correcting splicing and restoring BTK both ex vivo

SUMMARY. An 18-year-old white man with congenital agammaglobulinemia that was probably sex-linked developed clinically and pathologically typical regional enteritis. The association of these diseases provides evidence that antibody is not directly involved in the pathogenesis of regional enteritis and that plasma cells, a usual histologic feature of regional enteritis, are not essential. Antibody lack probably does not predispose to regional enteritis, and cellular immunity may be important in its pathogenesis. ...
INTRODUCTION: Common variable immunodeficiency and X-linked agammaglobulinaemia are primary immunodeficiencies classified as antibody deficiencies, and they both result in hypogammaglobulinaemia. OBJECTIVE: Evaluate the lipid profile and other cardiovascular risk biomarkers in CVID and XLA patients. METHODS: In total, 24 patients and 12 healthy controls matched by age and gender were included in the study. We evaluated anthropometric measurements, and seric total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), triglycerides (TG), apo A-I, small dense LDL (sdLDL), C-reactive protein (CRP), and tumour necrosis factor alpha (TNF-alpha), myeloperoxidase (MPO), cholesteryl ester transfer protein (CETP), and lecithin cholesterol acyltransferase (LCAT) were assessed ...
Results Rheumatological manifestations were seen in 27.4% patients of XLA. Thirteen out of 17 patients had a proven mutation in Btk gene. Mean age at symptom onset was 3.3 years (range 6 months - 13 years) and mean age at diagnosis of XLA was 5.6 years (range 1.5- 10 years). Rheumatological manifestations were seen at a mean age of 8.7 years (range 1.5- 20 years). In 2 patients, arthritis preceded the diagnosis of XLA while 10 patients developed rheumatological manifestations after the diagnosis of XLA. Arthritis as an initial presentation of XLA was seen in 5 patients.. Oligoarthritis was the most common presentation seen in 15 patients. Knee was the most commonly involved joint (11 patients) followed by ankle joint in 5 patients and shoulder, wrist and hip arthritis in 2 patients each. One patient each had arthritis involving proximal interphalangeal joints of both hands, clinical evidence of sacroiliitis and spondylodiscitis involving L4-5 and L5-S1 vertebrae. Three patients manifested as ...

Almost all of the adults with XLA had chronic medical problems; however, these problems did not interfere with normal daily activities, and the quality of life in this group was equivalent to that of the general male population of the United States," said Vanessa Howard, R.N., M.S.N., a nurse practitioner for the Immunology service at St. Jude and first author of the paper. "In the past, the majority of patients with XLA died of acute or chronic infections in the first two decades of life," Howard noted. "But in the last 20 years the outlook for patients with XLA has significantly improved, thanks to earlier diagnosis and improved gamma globulin therapy. Our study is reassuring and helps to put into perspective the ability of such patients to thrive with proper care, despite this potentially devastating disease ...

In recent years several rare autosomal recessive disorders that result in antibody deficiency have been reported. Some antibody deficiencies are part of a more broadly expressed systemic disorder or part of an immunodeficiency that affects T cells and/or NK cells as well as B cells. The possibility of immunodeficiency should be considered in any patient who is hospitalized for a major infection requiring intravenous therapy. Most patients with X-linked agammaglobulinemia (XLA) develop recurrent or persistent infections in the first 4 to 8 months of life, and the majority are recognized to have immunodeficiency at less than 3 years of age. Defects in μ heavy chain account for about one-third of the patients with autosomal recessive agammaglobulinemia. Mutation detection is the most practical way of making a definitive diagnosis. Single gene defects of the immune system may have features in common with common variable immunodeficiency (CVID). Recent studies suggest that analysis of B-cell phenotype may

Wnts are secreted ligands that activate several receptor-mediated signal transduction cascades. Homeostatic Wnt signaling through β-catenin is required in adults, because either elevation or attenuation of β-catenin function has been linked to diverse diseases. To contribute to the identification of both protein and pharmacological regulators of this pathway, we describe a combinatorial screen that merged data from a high-throughput screen of known bioactive compounds with an independent focused small interfering RNA screen. Each screen independently revealed Brutons tyrosine kinase (BTK) as an inhibitor of Wnt-β-catenin signaling. Loss of BTK function in human colorectal cancer cells, human B cells, zebrafish embryos, and cells derived from X-linked agammaglobulinemia patients with a mutant BTK gene resulted in elevated Wnt-β-catenin signaling, confirming that BTK acts as a negative regulator of this pathway. From affinity purification-mass spectrometry and biochemical binding studies, we ...

Chronic lymphocytic leukemia (CLL) is a common adult leukemia that is currently incurable outside of stem cell transplantation. Although response to IgM ligation is variable, the B-cell receptor (BCR) signaling pathway is aberrantly active in this disease, with antigen-dependent1,2 or -independent autonomous activation,3 leading to constitutive activation of kinases inducing cell survival and proliferation.4⇓⇓-7 One BCR pathway kinase that is uniformly overexpressed at the transcript level8 and constitutively phosphorylated in CLL is Brutons tyrosine kinase (BTK). Ibrutinib, an orally bioavailable irreversible inhibitor of BTK, has recently been shown to have outstanding clinical activity in CLL with extended durable remissions in both untreated and relapsed disease.9. BTK is a critical mediator of B-lymphocyte signaling and development. Mutations in various domains are responsible for X-linked agammaglobulinemia,10,11 a disorder characterized by developmental arrest of B cells and profound ...
Neutrophils are the earliest responding cells in the innate immune defense against pathogens. They migrate to the site of infection and produce reactive oxygen species (ROS), through the activity of the NADPH oxidase, and antimicrobial peptides to kill invading pathogens. Deficient ROS production leads to life-threatening infections, whereas overproduction of ROS results in tissue damage; thus, the activity of the NADPH oxidase is tightly regulated. Noting that patients with X-linked agammaglobulinemia (XLA), which is caused by a deficiency in the Tec kinase Btk, have neutropenia (reduced numbers of neutrophils), Honda et al. investigated a role for Btk in neutrophil ROS production and apoptosis. Btk is well characterized in its role in mediating the survival and differentiation of B cells, as well as in signaling downstream of Toll-like receptors (TLRs). Neutrophils from XLA patients activated with the stimulant PMA or with various TLR ligands produced more ROS than did similarly stimulated ...
Brutons tyrosine kinase (BTK) is a non-receptor kinase that plays a crucial role in oncogenic signaling that is critical for proliferation and survival of leukemic cells in many B cell malignancies. BTK was initially shown to be defective in the primary immunodeficiency X-linked agammaglobulinemia (XLA) and is essential both for B cell development and function of mature B cells. Shortly after its discovery, BTK was placed in the signal transduction pathway downstream of the B cell antigen receptor (BCR). More recently, small-molecule inhibitors of this kinase have shown excellent anti-tumor activity, first in animal models and subsequently in clinical studies ...

infection (Wintrobe & Hasenbush, 1939) and we now know that most patients will develop low levels of immunoglobulin if cases are followed for long enough. Hypogammaglobulinaemia was first recognized as a clinical entity by Bruton (1952), when electrophoresis of serum revealed the surprising absence of the gamma fraction in an otherwise normal pattern. Immunological studies showed a complete absence of antibodies and isohaemagglutinins. Odd case reports of agammaglobulinaemia in CLL began appearing shortly afterwards (Brem & Morton, 1955; Jim & Reinhard, 1956). Jim (1957) found that 17 out of 50 patients had hypogammaglobulinaemia. In a more comprehensive study, Cone & Uhr (1964) found deficiencies in all classes of serum immunoglobulins and failure to produce an antibody response to phi x 174, a primary antigen, or diphtheria toxoid, a secondary antigen. There was also a failure to sensitize to dinitrofluorobenzene, although most patients did produce a delayed hypersensitivity response to recall ...
Polyclonal lymphocyte and plasma cell disorders can be classified into two major groups: primary disorders and acquired disorders. See Table 48-1.. - Primary disorders result from defects intrinsic to B lymphocytes (eg, X-linked agammaglobulinemia), T lymphocytes (eg, congenital thymic aplasia), and/or natural killer cells, the latter usually coupled with a B- or T-cell deficiency (eg, interleukin-7 receptor α-chain deficiency) (see Chap. 50).. - Acquired disorders result from physiologic or pathophysiologic responses to extrinsic factors, usually infectious agents (eg, Epstein-Barr virus or human immunodeficiency virus infection) (see Chaps. 51 and 52). ...

A substantial proportion of patients had adverse cytogenetic markers: 33% had deletion 17p and 35% had deletion 11q.. The adverse events were very similar to those reported in the MCL study. Most adverse events were grade 2 or lower. Overall, the most common reactions were diarrhea (49%), upper respiratory tract infection (33%), fatigue (32%), cough (31%), arthralgia (27%), rash (27%), and pyrexia (27%). Adverse events led to discontinuation of treatment in 2 patients in the 420-mg cohort (4%) and 4 patients in the 840-mg cohort (11%). Pneumonia (12%) and dehydration (6%) were the most frequent grade 3 or higher adverse events. Grade 3 or higher infections were most common early in the course of therapy.. Congenital BTK deficiency can lead to the immunodeficient state known as agammaglobulinemia, and a question had been raised regarding whether ibrutinib would induce hypogammaglobulinemia in patients. In the studies by Advani and colleagues and Byrd and coworkers, it appears that ibrutinib does ...

Tirabrutinib HCl, also known as ONO-4059 HCl, is a potent and orally active Bruton agammaglobulinemia tyrosine kinase (BTK) in hibitor. Upon administration, ONO-4059 covalently binds to BTK within B cells, thereby preventing B-cell receptor signaling and impeding B-cell development. As a result, this agent may inhibit the proliferation of B-cell malignancies. BTK, a cytoplasmic tyrosine kinase and member of the Tec family of kinases, plays an important role in B lymphocyte development, activation, signaling, proliferation and survival.

Airborne spread or skin-to-skin contact. Like EBV, infection is more severe if primary infection of adult. Patients at risk are (1) adults, (2) pregnant women in their 3rd trimester and (3) immunocompromised patients.

But children with isolated agammaglobulinemia are not at risk. ...
Infections post-transplant are common, but it is difficult to predict which patients are most at risk. Hypogammaglobulinemia is a known risk factor for infection. In this prospective, single-center observational study, low immunoglobulin levels were common post-transplant, and correlated with an increased risk of infection. This study raises the question of whether such monitoring should become routine practice, and whether giving immunoglobulin replacement to patients with demonstrated low levels would reduce infection rates.. ...
The immune status of children with malignant disease in remission was assessed usingvarious immune function tests. Children with infections had significantlymore neutropenia, hypogammaglobulinaemia, and impaired cell-mediated immune responses than those without. These two groups combined had much more absolute lymphopenia and impairment of both cell-mediated immunity and antibody-producing capacity thancontrol children with non-malignant conditions. Regular immunological evaluation isrecommended for children with malignant disease when new intensive treatment schedules are under trial and for individual patients particularly prone to develop infections during treatment. ...
Purpose: Targeting the B-cell receptor (BCR) pathway with inhibitors of Bruton tyrosine kinase (BTK) and PI3Kδ is highly effective for the treatment of chronic lymphocytic leukemia (CLL). However, deep remissions are uncommon, and drug resistance with single-agent therapy can occur. In vitro studies support the effectiveness of combing PI3Kδ and BTK inhibitors.. Experimental Design: As CLL proliferation and survival depends on the microenvironment, we used murine models to assess the efficacy of the BTK inhibitor acalabrutinib combined with the PI3Kδ inhibitor ACP-319 in vivo. We compared single-agent with combination therapy in TCL1-192 cell-injected mice, a model of aggressive CLL.. Results: We found significantly larger reductions in tumor burden in the peripheral blood and spleen of combination-treated mice. Although single-agent therapy improved survival compared with control mice by a few days, combination therapy extended survival by over 2 weeks compared with either single agent. The ...

More than 600 different mutations in the BTK gene have been found to cause X-linked agammaglobulinemia (XLA). Most of these mutations result in the absence of the BTK protein. Other mutations change a single protein building block (amino acid), which probably leads to the production of an abnormal BTK protein that is quickly broken down in the cell. The absence of functional BTK protein blocks B cell development and leads to a lack of antibodies, causing an increased susceptibility to infections in people with XLA.. Some people with XLA have large DNA deletions that remove one end of the BTK gene and all of a neighboring gene known as TIMM8A. Mutations in TIMM8A cause deafness-dystonia-optic neuronopathy (DDON) syndrome, which is characterized by hearing loss, vision problems, a decline in intellectual function (dementia), and involuntary muscle tensing (dystonia) or difficulty coordinating movements (ataxia). Individuals with large DNA deletions that include the BTK gene and the TIMM8A gene ...

DESCRIPTION (provided by applicant): Brutons tyrosine kinase (Btk) is the target for mutations that cause X-linked agammaglobulinemia (XLA) in man and X-linked immunodeficiency (Xid) in mouse. Both mouse and man have reduced circulating B cells and display defective B cell survival and tolerance. These defects have been primarily attributed to Btk function in B cell antigen receptor (BCR) signaling. Preliminary data presented in this exploratory grant application demonstrate that Btk couples B-cell activation factor receptor (BAFF-R), a TNF-R family member, to the NF- kB pathway and facilitates B cell survival in response to its ligand, BAFF. Emerging evidence suggests that BAFF-R is as critical in B cell survival as BCR. As such, this proposal focuses on defining the molecular mechanisms by which Btk mediates BAFF-R signaling to NF-kB and peripheral B cell survival. Preliminary data further suggests that (i) Btk interfaces with BAFF-R via mechanisms involving TRAF2 and cIAP2, and (ii) Btk ...

Primary immunodeficiency diseases (PIDDs) are genetically determined disorders of the immune system resulting in greatly enhanced susceptibility to infectious disease, autoimmunity and malignancy. As most subjects with PIDDs present with infections, the differential diagnosis and initial investigations for an underlying immune defect are typically guided by the clinical presentation. In subjects with PIDDs, individual infections are not necessarily more severe than those that occur in a normal host. Rather, the clinical features suggestive of an immune defect may be the recurring and/or chronic nature of infections with common pathogens that may result in end organ damage, such as bronchiectasis. Several immune globulin products have already been approved by the FDA ...

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 ...

The serum and urine immunoglobulin concentrations of a patient with congenital nephrotic syndrome of the Finnish type (CNS) were studied during an 11 month period. The serum IgG levels were never higher than 25% and most were below 2% of normal infant values. Serum IgM levels rose to three times normal and IgA concentrations varied. The selective protein index (SPI) showed apparent selective proteinuria (SPI less than 0.06). Intravenous gamma-globulin infusions were carried out to raise serum IgG levels. The infused IgG was initially contained within the intravascular space, but within 30 hours 55% was lost in the urine. Compared to the steady state, the renal clearance of IgG showed a 20-fold increase immediately post-infusion. We conclude that children with CNS should be considered essentially agammaglobulinemic throughout the first year of life and perhaps longer. Intravenous IgG infusions provide only hours of sufficient IgG replacement due to rapid urinary losses and may be detrimental.

Also known as ACP-196, acalabrutinib is also considered a second generation BTK inhibitor because it was rationally designed to be more potent and selective than ibrutinib, theoretically expected to demonstrate fewer adverse effects owing to minimized bystander effects on targets other than BTK. Nevertheless, acalabrutinib was approved under the FDAs accelerated approval pathway, which is based upon overall response rate and faciliates earlier approval of medicines that treat serious
HealthTap: Doctor answers on Symptoms, Diagnosis, Treatment, and More: Dr. Chinen on what is auto immune deficiency: Humoral immunodeficiency is a deficiency of circulating antibodies.
Primary humoral immunodeficiency or primary immune deficiency diseases (PIDD) is a group of disorders in which the immune system of an individual does not function properly. In PIDD patients, the number of antibodies produced in the body is not sufficient, or the ones produced are defective. PIDDs are thus often characterized by increased vulnerability to infections. According to the International Union of Immunological Societies (IUIS), PIDD is a compilation of more than 150 different diseases.. Request for Sample Report: http://www.mrrse.com/sample/3381.

TY - JOUR. T1 - Membranous nephropathy in a 13-year-old boy with common variable immunodeficiency. AU - Yim, Hyung-Eun. AU - Yoo, Kee Hwan. PY - 2012/12/1. Y1 - 2012/12/1. N2 - Various forms of hypogammaglobulinemia can occur in patients with autoimmune diseases and vice versa. We report a 13-yr-old boy with membranous nephropathy and common variable immunodeficiency. He presented with the nephrotic syndrome, pneumonia with bronchiectasis, and profound hypogammaglobulinemia. Renal biopsy showed diffusely thickened glomerular capillary walls with spikes suggesting a membranous nephropathy. Secondary causes were ruled out by laboratory studies;however, heavy proteinuria persisted with steroid therapy. Cyclosporine and intravenous immunoglobulin were added, and the patient was discharged with decreased proteinuria. Hypogammaglobulinemia may have a deleterious impact on the immune dysregulation in some patients with membranous nephropathy.. AB - Various forms of hypogammaglobulinemia can occur in ...
The etiology of primary antibody deficiencies is largely unknown. Beside rare monogenic forms, the majority of cases seem to have a more complex genetic basis. Whereas common variable immunodeficiency has been investigated in-depth, only few reports exist on milder primary antibody deficiencies like idiopathic primary hypogammaglobulinemia and IgG subclass deficiency. We performed flow cytometric immunophenotyping in 33 common variable immunodeficiency, 23 idiopathic primary hypogammaglobulinemia and 21 IgG subclass deficiency patients, and in 47 asymptomatic first-degree family members of patients and 101 unrelated healthy controls. All three patient groups showed decreased memory B and naive T cell subsets and decreased B-cell activating factor receptor expression. In contrast, circulating follicular helper T cell frequency and expression of inducible T-cell co-stimulator and chemokine receptors were significantly altered in common variable immunodeficiency patients only. Asymptomatic ...

Primary immunodeficiencies are disorders in which part of the bodys immune system is missing or does not function normally. To be considered a primary immunodeficiency, the cause of the immune deficiency must not be secondary in nature (i.e., caused by other disease, drug treatment, or environmental exposure to toxins). Most primary immunodeficiencies are genetic disorders; the majority are diagnosed in children under the age of one, although milder forms may not be recognized until adulthood. While there are over 100 recognized PIDs, most are very rare. About 1 in 500 people in the United States are born with a primary immunodeficiency. Immune deficiencies can result in persistent or recurring infections, autoinflammatory disorders, tumors, and disorders of various organs. There are currently no cures for these conditions; treatment is palliative and consists of managing infections and boosting the immune system. The precise symptoms of a primary immunodeficiency depend on the type of defect. ...
AIMS: (1) To assess a range of intravenous immunoglobulin products for atypical classical antineutrophil cytoplasmic antibody (C-ANCA) staining and to determine if this is present in patients treated with high dose intravenous immunoglobulin (2 g/kg/month) and replacement doses (200 mg/kg fortnightly); (2) using the United Kingdom national external quality assessment scheme (NEQAS), to determine if laboratories could differentiate this pattern from classical ANCA. METHODS: ANCA testing was performed on 30 batches of intravenous immunoglobulin from several manufacturers. Six patients treated with high dose intravenous immunoglobulin and 11 receiving replacement doses of immunoglobulin for hypogammaglobulinaemia were tested for ANCA by indirect immunofluorescence on cytospin preparations of ethanol fixed neutrophils and by enzyme linked immunosorbent assay (ELISA). One of the positive immunoglobulin batches was tested blindly by 125 laboratories involved in NEQAS by indirect immunofluorescence and ...
According to an international team of researchers, having selective IgA deficiency (sigAD) or common variable immunodeficiency (CVID) affects how much antibodies a persons immune system can produce. Having either condition may result in recurrent infections. Using the Rochester Epidemiology Projects linkage system, the team found that patients with a history of asthma had an increased chance of also having SigAD or CVID..
