This article explains the recovery period for common variable immune deficiency (CVID), prognosis/outlook, prevention, coping and yoga for common variable immune deficiency (CVID).
Patients with common variable immunodeficiency disorders are monitored for liver function test abnormalities. A proportion of patients develop deranged liver function and some also develop hepatomegaly. We investigated the prevalence of abnormalities and types of liver disease, aiming to identify those at risk and determine outcomes. The local primary immunodeficiency database was searched for patients with a common variable immunodeficiency disorder and abnormal liver function and/or a liver biopsy. Patterns of liver dysfunction were determined and biopsies reviewed. A total of 47 of 108 patients had deranged liver function, most commonly raised alkaline phosphatase levels. Twenty-three patients had liver biopsies. Nodular regenerative hyperplasia was found in 13 of 16 with unexplained pathology. These patients were more likely to have other disease-related complications of common variable immunodeficiency disorders, in particular non-coeliac (gluten insensitive) lymphocytic enteropathy. ...
Common variable immune deficiency is definitely a heterogeneous immune deficiency characterized by reduced serum immunoglobulins and a lack of antibodies. As these ethnicities are time-consuming, not standardized and the results are based on the activators used, more recently CVID subjects have been classified from the phenotype of unstimulated peripheral blood B cells. Here, we discuss the B-cell problems in CVID and the medical consequences of these abnormalities, and explore how these studies may lead to a better understanding of this complex immune defect. B lymphocytes arise from hemopoietic stem cells in the bone marrow. Early progenitor B cells are characterized by progressive variable-diversity-joining recombination, first of the Ig weighty chain, followed by the surrogate light chains, to produce a pre-B-cell receptor (BCR) [5]. B cells are characterized by the surface expression of CD19, among other characteristics. Progression to the immature B cell occurs after a mature light chain ...

Common variable immunodeficiency (CVID) is the most frequent primary immunodeficiency (PID) in adulthood and is characterized by severe reduction of immunoglobulin serum levels and impaired antibody production in response to vaccines and pathogens. Beyond the susceptibility to infections, CVID encompasses a wide spectrum of clinical manifestations related to a complex immune dysregulation that also affects liver. Although about 50% CVID patients present persistently deranged liver function, burden, and nature of liver involvement have not been systematically investigated in most cohort studies published in the last decades. Therefore, the prevalence of liver disease in CVID widely varies depending on the study design and the sampling criteria. This review seeks to summarize the evidence about the most relevant causes of liver involvement in CVID, including nodular regenerative hyperplasia (NRH), infections and malignancies. We also describe the clinical features of liver disease in some monogenic forms
Germinal center follicular T helper (GCTfh) cells are essential players in the differentiation of B cells. Circulating follicular T helper (cTfh) cells share phenotypic and functional properties with GCTfh cells. Distinct subpopulations of cTfh with different helper capabilities towards B cells can be identified: cTfh1 (CXCR3+CCR6-), cTfh2 (CXCR3-CCR6-) and cTfh17 (CXCR3-CCR6+). Alterations in cTfh function and/or distribution have been associated with autoimmunity, infectious diseases and more recently with several monogenic immunodeficiencies. Common variable immunodeficiency disease (CVID) is the commonest symptomatic primary immunodeficiency (PID) with a genetic cause identified in only 2-10% of patients. Although a heterogeneous disease, most patients show a characteristic defective B cell differentiation into memory B cells or antibody secreting cells. We investigated if alterations in CVID cTfh cells frequency or distribution into cTfh1, cTfh2, cTfh17 subpopulations and regulatory follicular T

Common Variable Immune Deficiency (CVID) is a syndrome containing a spectrum of disorders which results in weakened immunity and recurrent infections. The ESID (European Society for Immunodeficiencies) CVID definition includes patients with marked decrease of IgG (at least 2 standard deviations below the mean for age). Patients must also have disease onset at an age over 2 years, absent isohaemagglutinins and/or response to vaccines and other defined causes of hypogammaglobulinaemia must be excluded. The Euroclass system of classifying CVID is the result of a European multicentre trial attempting to develop a consensus of two existing classification schemes of B-cell immunophenotyping. In this paper it was shown that B-cell immunophenotype correlated with coincidence of clinical sequelae and it suggested implementing this to further classify CVID to give prognostic and therapeutic information. However, it has not yet been shown that these alterations in B-cell immunophenotype are the result of ...

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 ...
Common Variable Immunodeficiency (CVID) What is common variable immunodeficiency (CVID)? CVID is an immunodeficiency disorder characterized by a low level of antibodies, making it difficult for the childs body to fight diseases. The child then becomes sick with recurrent infections. The disease may become evident during infancy, childhood, puberty, or even later into adulthood. The symptoms of the disease are very different for each child affected, which is why it is called a variable group of disord...
A 57 yo male with a background history of common variable Immunodeficiency syndrome (CVID) on Immunoglobulin Infusion (Kiovig) 40mg three weekly was referred for investigation of diarrhoea and follow up from previous history of colonic polyps.Colonoscopy showed an irregular looking ileocaecal valve (ICV) with an adjacent flat polyp (Paris IIa). Biopsies showed low grade dysplasia. There was also a duodenal polyp noted on gastroscopy and biopsy again showed low grade dysplasia. In light of the findings of upper and lower gastrointestinal tract polyps, a small bowel capsule endoscopy (SBCE) was arranged. This showed an irregular area of mucosa in the proximal small bowel with significant ulceration and inflammation (Figure 1). There were also multiple scattered lymphagiectasias and lymphoid hyperplasia in the distal small bowel (Figure 2).Anterograde double ballon enteroscopy (ADBE) was subsequently performed to the distal jejunum about 8 weeks after the SBCE. The duodenal polyp seen at gastroscopy was
Common variable immunodeficiency (CVID), the most common primary immunodeficiency seen in clinical practice, represents a heterogeneous group of syndromes characterised serologically by low antibody levels and clinically by recurrent respiratory tract infections, granulomatous inflammation and autoimmunity. The choice of IRT administration modalities includes subcutaneous (SC), facilitated subcutaneous (fSC) and intravenous (IV) routes. The different routes are thought to be equivalent in their therapeutic effects. However, there are clear pharmacokinetic differences between the delivery methods. It is unclear whether these differences have a clinically relevant impact on inflammation. This is an important issue as such differences might have an impact on administration modality. We will investigate the effects on systemic inflammation and immune activation of different modalities of Immunoglobulin Replacement Therapy in Common Variable Immune Deficiency.. This pilot study will examine ...
Common variable immunodeficiency (CVID) is the most frequent symptomatic primary antibody deficiency in adulthood and is characterized by the marked reduction of IgG and IgA serum levels. Thanks to the successful use of polyvalent immunoglobulin replacement therapy to treat and prevent recurrent infections, non-infectious complications, including autoimmunity, polyclonal lymphoproliferation and malignancies, have progressively become the major cause of morbidity and mortality in CVID patients. The management of these complications is particularly challenging, often requiring multiple lines of immunosuppressive treatments. Over the last 5-10 years, the anti-CD20 monoclonal antibody (i.e., rituximab) has been increasingly used for the treatment of both autoimmune and non-malignant lymphoproliferative manifestations associated with CVID. This review illustrates the evidence on the use of rituximab in CVID. For this purpose, first we discuss the mechanisms proposed for the rituximab mediated B-cell
Background/objectives: the common variable immunodeficiency (CVID) is known as the most prevalent symptomatic primary immune deficiency (PID) diseases, which is characterized by lower antibody serum levels as well as several infectious and noninfectious manifestations. In this regard, Bronchiectasis is considered as a common respiratory complication and a vital challenge in CVID cases. This study aimed to evaluate the prevalence of bronchiectasis and investigate its association with other manifestations in CVID patients. Methods: A total of 297 patients diagnosed with CVID according to the relevant criteria were included in the current study. The query was performed to collect the participants demographic data, clinical manifestations, and laboratory findings. The analysis was performed between the two groups of the study including CVID patients with bronchiectasis and those without it. Results: Overall, the prevalence rate of bronchiectasis was calculated to be 28.3%. Also, CVID patients with

Common variable immune deficiency (CVID) is a disorder that impairs the immune system. People with CVID are highly susceptible to infection from foreign invaders such as bacteria, or more rarely, viruses and often develop recurrent infections, particularly in the lungs, sinuses, and ears. Pneumonia is common in people with CVID. Over time, recurrent infections can lead to chronic lung disease. Affected individuals may also experience infection or inflammation of the gastrointestinal tract, which can cause diarrhea and weight loss. Abnormal accumulation of immune cells causes enlarged lymph nodes (lymphadenopathy) or an enlarged spleen (splenomegaly) in some people with CVID. Immune cells can accumulate in other organs, forming small lumps called granulomas.Approximately 25 percent of people with CVID have an autoimmune disorder, which occurs when the immune system malfunctions and attacks the bodys tissues and organs. The blood cells are most frequently affected by autoimmune attacks in CVID; ...

Common variable immunodeficiency (CVID) is the most prevalent symptomatic primary immunodeficiency in adults. CVID clinically presents with a history of recurrent infections at mucous membranes which is the consequence of a marked hypogammaglobulinemia [1]. The clinical course of CVID is complicated by a plethora of systemic immunopathology including autoimmunity, lymphoproliferation, malignancy and sarcoid-like granulomas.. CVID affects males and females equally and usually manifests in the second or third decade of life. A second peak of onset exists in childhood between the ages of 2 and 5 years [2, 3]. The prevalence of CVID in the Western hemisphere is estimated to be approximately 1: 25.000 [1, 4].. The majority of CVID cases are sporadic, while approximately 10 to 20% of CVID cases show at least one additional family member affected either by CVID or selective IgA deficiency (sIgAD) [5, 6]. Most multiplex CVID families show an autosomal dominant mode of inheritance but about 20% present ...
2014, Springer Science+Business Media New York. Purpose: Common variable immunodeficiency (CVID) is the most frequent form of primary symptomatic hypogammaglobulinemia. CVID patients display a number of abnormalities in lymphocyte subpopulations including chronic T-cell activation and decreased numbers of circulating CD4+ T cells and NK cells. We and others have recently shown that CVID is associated with increased concentration of soluble CD14 (sCD14) and other factors indicating limited microbial translocation.Methods: To address the mechanisms of chronic immune activation in CVID, we performed a detailed analysis of cytokine serum levels in 36 patients with CVID, 52 patients with selective IgA deficiency (IgAD), and 56 healthy volunteers.Results: We show that CVID is associated with elevated serum levels of CXCL-10/IP-10, IL-1R antagonist, TNF-α, IL-10, IL-12 (p40), CCL-2/MCP-1, G-CSF, and CCL-11/eotaxin. The detected cytokine signature is consistent with an ongoing activation of cells of ...
Common Variable Immunodeficiency (CVID) is the most prevalent primary antibody deficiency, and characterized by defective generation of high-affinity antibodies. Patients have therefore increased risk to recurrent infections of the respiratory and intestinal tract. Development of high-affinity antigen-specific antibodies involves two key actions of B-cell receptors (BCR): transmembrane signaling through BCR-complexes to induce B-cell differentiation and proliferation, and BCR-mediated antigen internalization for class-II MHC-mediated presentation to acquire antigen-specific CD4(+) T-cell help.We identified a variant (L3P) in the B-lymphoid tyrosine kinase (BLK) gene of 2 related CVID-patients, which was absent in healthy relatives. BLK belongs to the Src-kinases family and involved in BCR-signaling. Here, we sought to clarify BLK function in healthy human B-cells and its association to CVID.BLK expression was comparable in patient and healthy B-cells. Functional analysis of L3P-BLK showed reduced BCR

N2 - Increased proportions of naive B cell subset and B cells defined as CD27negCD21negCD38neg are frequently found in patients with common variable immunodeficiency (CVID) syndrome. Current methods of polychromatic flow cytometry and PCR-based detection of k deletion excision circles allow for fine definitions and replication history mapping of infrequent B cell subsets. We have analyzed B cells from 48 patients with CVID and 49 healthy controls to examine phenotype, frequency, and proliferation history of naive B cell subsets. Consistent with previous studies, we have described two groups of patients with normal (CVID 21norm) or increased (CVID 21lo) proportions of CD27negCD21negCD38neg B cells. Upon further analyses, we found two discrete subpopulations of this subset based on the expression of CD24. The B cell subsets showed a markedly increased proliferation in CVID 21lo patients as compared with healthy controls, suggesting developmental arrest rather than increased bone marrow output. ...

Females have a longer lifespan and better general health than males. Considerable number of studies also demonstrated that, after trauma and sepsis, females present better outcomes as compared to males indicating sex-related differences in the innate immune response. The current notion is that differences in the immuno-modulatory effects of sex hormones are the underlying causative mechanism. However, the field remains controversial and the exclusive role of sex hormones has been challenged. Here, we propose that polymorphic X-linked immune competent genes, which are abundant in the population are important players in sex-based immuno-modulation and play a key role in causing sex-related outcome differences following trauma or sepsis ...
Background: Common variable immunodeficiency (CVID) is a primary immune disorder associated with hypogammaglobulinemia, recurrent infections and autoimmune diseases. CVID patients are frequently in contact with infectious pathogens leading to the activation of innate immunity through Toll-like receptors (TLR) affecting adaptive immunity. The aim of the present study was to test the immunomedulatory effect of small molecule G2013, a novel designed non-steroidal anti-inflammatory agent in CVID. Materials and Methods: After blood sampling from 16 CVID patients and 16 age- and sex-matched healthy controls, peripheral blood mononuclear cells (PBMCs) were isolated and treated with/without lipopolysaccharide (LPS), lipopolyteichoic acid (LTA), and G2013. Assessing the immunomodulatory effect of G2013, flowcytometry was done for quantify the protein expression of TLR2 and TLR4. Gene expressions of signaling molecules involved in the TLR2 and TLR4 pathways were assessed by real-time PCR. ELISA performed

Lack of antibodies, recurrent infections, adrenocorticotropic hormone (ACTH) deficiency and autoimmune hair loss are features in patients that have been associated with mutations in the NFKB2 gene(2,6). We therefore postulated a causative NFKB2 gene defect in two unrelated cases from Epsom & St. Helier University Hospitals, with these clinical features. To verify this, we sequenced the NFKB2 gene in these patients, measured the expression of protein p100, evaluated B- and T-cell subsets and performed quantitative functional assessment of the non-canonical NFκB signalling pathway.. Sequencing identified novel heterozygous genetic variants at position 2604 in the NFKB2 gene in both patients, causing the same amino acid change i.e tyrosine to termination at position 868 in the encoded protein p100. This resulted in a truncated form of p100, p100Δ33, which is 33 amino acids shorter than the normal form of the protein. Interestingly, this mutation in the two unrelated patients is identical to that ...

This study assesses histological and genetic alterations in the gastric mucosa of patients with CVID and correlates these withH pylori infection. The prevalence ofH pylori infection was greater than that reported elsewhere.18 24 However, in these studies, the presence of the bacterium was only determined by histology (without Giemsa staining) on a single antral and a single gastric body biopsy specimen. It is possible that the prevalence of H pylori infection was therefore underestimated in these studies. In addition, the general prevalence of this infection in Italy is higher than that found in the United Kingdom and United States,25 increasing the likelihood of transmission to these patients. In addition, no patient was on prophylactic antibiotic therapy in our cohort.. Our results show that the prevalence of chronic active gastritis involving both antrum and body was significantly higher inH pylori positive (79%) thanH pylori negative (20%) patients. Moreover, MAG was observed more frequently ...
