Janssen LMA, van der Flier M, de Vries E. Lessons Learned From the Clinical Presentation of Common Variable Immunodeficiency Disorders: A Systematic Review and Meta-Analysis. Front Immunol 2021; 12:620709. [PMID: 33833753 PMCID: PMC8021796 DOI: 10.3389/fimmu.2021.620709] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Accepted: 02/24/2021] [Indexed: 12/22/2022] Open
Abstract
Background Diagnostic delay in common variable immunodeficiency disorders (CVID) is considerable. There is no generally accepted symptom-recognition framework for its early detection. Objective To systematically review all existing data on the clinical presentation of CVID. Methods PubMed, EMBASE and Cochrane were searched for cohort studies, published January/1999-December/2019, detailing the clinical manifestations before, at and after the CVID-diagnosis. Results In 51 studies (n=8521 patients) 134 presenting and 270 total clinical manifestations were identified. Recurrent upper and/or lower respiratory infections were present at diagnosis in 75%. Many patients had suffered severe bacterial infections (osteomyelitis 4%, meningitis 6%, septicemia 8%, mastoiditis 8%). Bronchiectasis (28%), lymphadenopathy (27%), splenomegaly (13%), inflammatory bowel disease (11%), autoimmune cytopenia (10%) and idiopathic thrombocytopenia (6%) were also frequently reported. A bimodal sex distribution was found, with male predominance in children (62%) and female predominance in adults (58%). 25% of CVID-patients developed other manifestations besides infections in childhood, this percentage was much higher in adults (62%). Immune-dysregulation features, such as granulomatous-lymphocytic interstitial lung disease and inflammatory bowel disease, were more prominent in adults. Conclusions The shift from male predominance in childhood to female predominance in adults suggests differences in genetic and environmental etiology in CVID and has consequences for pathophysiologic studies. We confirm the high frequency of respiratory infections at presentation, but also show a high incidence of severe bacterial infections such as sepsis and meningitis, and immune dysregulation features including lymphoproliferative, gastrointestinal and autoimmune manifestations. Early detection of CVID may be improved by screening for antibody deficiency in patients with these manifestations.

Abstract
Objectives: Common variable immunodeficiency (CVID) is the most common symptomatic inborn error of immunity characterized by variable clinical manifestations. Methods: Web of Science, Scopus, and PubMed databases were searched systemically to find eligible studies from the earliest available date to February 2020 with standard keywords. Pooled estimates of the autoimmunity prevalence and the corresponding 95% confidence intervals (CI) were calculated using random-effects models. Results: The overall prevalence of autoimmunity was 29.8% (95% CI: 26.4-33.3; I2 = 82.8%). The prevalences of hematologic autoimmune diseases, autoimmune gastrointestinal disorders, autoimmune rheumatologic disorders, autoimmune skin disorders, and autoimmune endocrinopathy in CVID patients were 18.9%, 11.5%, 6.4%, 5.9%), and 2.5%, respectively. There were significantly higher lymphocyte, CD3 + T cell, and CD4 + T cell count among CVID patients without autoimmunity (p< 0.05). Furthermore, failure to thrive, organomegaly, enteropathy, and meningitis was significantly higher in CVID patients with autoimmunity(p< 0.05). Conclusions: Many CVID patients could present with autoimmunity as part of the disease or even as the first or only clinical manifestation of the disease. Care providers may need to pay particular attention to the possible association of these two disorders since the co-occurrence of CVID and autoimmunity could be a misleading clue.

GLILD Revisited: Pulmonary Pathology of Common Variable and Selective IgA Immunodeficiency. Am J Surg Pathol 2020; 44:1073-1081.

Abstract
Common variable immunodeficiency (CVID) and selective immunoglobulin A deficiency (IgAD) often cause chronic lung disease, but the pulmonary pathologic features of these systemic diseases are poorly recognized by pathologists. It has been claimed that CVID cases show a characteristic combination of noncaseating granulomas-lymphoid proliferations termed granulomatous-lymphocytic interstitial lung disease (GLILD). We present 34 surgical lung biopsy cases of CVID and 4 of IgAD. Noncaseating granulomas were seen in 23/34 (68%) CVID and 2/4 (50%) IgAD cases. A statistically identical pattern of benign lymphoid proliferation was found in CVID and IgAD whether or not granulomas were present. Organizing pneumonia, sometimes considered a part of GLILD, was seen in 25/34 (74%) CVID and 2/4 (50%) IgAD cases and did not correlate with the presence of granulomas. On follow-up, 3 CVID patients died (only 1 of pulmonary disease), while 21 others are alive at 1 to 300 months with no difference by presence or absence of granulomas. Three IgAD patients with follow-up are alive. We conclude that CVID and IgAD are indistinguishable in surgical lung biopsies and a subset of both show patterns that would qualify as GLILD, while other cases lack granulomas but have identical patterns of lymphoid infiltration and organizing pneumonia. We suggest that GLILD is neither a specific nor a useful entity, and biopsies from CVID and IgAD patients should be diagnosed simply by microscopic pattern(s) observed. The prognosis of CVID with lymphoid infiltrates with or without granulomas in this series was good, contrary to claims in the literature about GLILD.

Abstract
Abstract
Purpose of Review
This review sought to assess the extent and causes of suboptimal healthcare outcomes for chronic variable immunodeficiency (CVID).
Recent Findings
Significant improvements in diagnostic technology and treatment protocols over time were found, leading to reduced morbidity and mortality for those accessing therapies. Treatments continue to be largely non-curative with financing (mainly insurance coverage) an obstacle. Symptom recognition by primary care practitioners (PCP) remains a gating factor to treatment and a widespread and persistent barrier to optimal health outcomes.
Summary
CVID is a subtype of primary immunodeficiency (PIDD) associated with under-diagnosis. It has emerged as a health issue more prevalent than historically known. No symptom-recognition framework for early detection of CVID has been generally accepted; those proposed for primary immunodeficiencies have shown low sensitivity, low specificity or both. Positive trends in cases diagnosed have been aided by awareness campaigns and international collaborations. However, treatments for CVID will not realize full potential without effective, accepted frameworks for timely identification in the clinic.

Abstract
Introduction In this study, we aimed to retrospectively evaluate the clinical and laboratory findings and complications of 28 common variable immunodeficiency (CVID) patients. Material and methods The clinical features and laboratory data of 28 CVID patients were evaluated. Results Nineteen patients were male. In 53.5% of the cases, complications included inflammatory bowel disease, cytopenia, bronchiectasis, granulomatous lymphocytic interstitial lung disease (ILD) and asthma. In their immunological evaluations, IgG, IgM, and IgA mean values were 474.8 ±214.1 mg/dl; 56.7 ±41.9 mg/dl; 35.3 ±58.2 mg/dl, respectively, and the vaccine response was positive in 64.2% of the cases. In all age groups, absolute lymphocyte counts, naive (CD19+IgD+27-), nonswitch (CD19+IgD-27+) memory B cells were numerically higher when compared to the data of healthy children; however, although switch memory (CD19+IgD+27+) B cells were proportionally low in the 4-8 and 12-18 age groups, they were low both numerically and proportionally in the 8-12 age group. No statistically significant difference was found between the cases with complications and without complications. But the cases with pulmonary complications were compared within the group, the CD8 ratio was high but the IgA level was low in patients with bronchiectasis and CD3 was numerically and proportionally low in the cases with ILD compared to others. According to the Paris classification, 11/27 (40.7%) of the cases, 3/27 (11.1%) of them and 13/27 (48.2%) of them were evaluated as MB0, MB1, and MB2, respectively. Conclusions In genetic studies, TACI (trans-membrane activator and calcium-modulating cyclophilin ligand interactor – TNFRSF13B) mutation was found positive in 25% of the cases.

Abstract
Background Common variable immunodeficiency (CVID) is a primary immunodeficiency disorder (PID) that typically presents with hypogammaglobulinemia and impaired antibody production. Objectives This study aimed to promote the awareness of CVID, whose clinical spectrum is quite broad. Methods The demographic, clinical, and laboratory characteristics of 12 children (seven males and five females) with CVID were analyzed retrospectively. The patients were diagnosed using the diagnostic criteria of the European Society for Primary Immunodeficiencies. Results The median disease onset age was 7.2 ± 4.1 years, and the mean diagnosis age was 11.6 ± 3.7 years. The diagnosis delay was 4.3 ± 2.6 years, and the parental consanguinity rate was 75%. Most patients presented with recurrent infections, including upper respiratory tract infections (n = 8), lower respiratory tract infections (n = 9), and gastroenteritis (n = 5). In addition, growth retardation (n = 9) and bronchiectasis (n = 5) were common comorbidities. Two patients presented with autoimmune thrombocytopenia and anemia, and one patient exhibited lung empyema. All the patients had immunoglobulin G deficiencies. Conclusion CVID is a heterogeneous disease, so the diagnosis is frequently delayed. In the CVID patients with pulmonary complications, relationships were seen with the diagnosis delay, symptom onset age, and lung infection prevalence. Overall, the early diagnosis and treatment of PIDs can preclude life-threatening complications.

Abstract
RATIONALE Granulomatous-lymphocytic interstitial lung disease (GLILD) has emerged as a major cause of morbidity in patients with common variable immunodeficiency (CVID). While GLILD is among the most serious noninfectious pulmonary complications of CVID, risk factors for this condition have not been reported. OBJECTIVES To identify clinical, physiologic, and serologic risk factors for GLILD in adults with CVID. METHODS Of 345 consecutive adult patients with CVID, we identified 34 in the National Jewish Health research database who had a radiographic-pathologic diagnosis of GLILD evaluated between 2002 and 2014. Each case was age and sex matched to 52 CVID control subjects. We used logistic regression to determine independent predictors of GLILD. A mixed effects model was used to estimate the longitudinal change in percent predicted FVC. MEASUREMENTS AND MAIN RESULTS The mean time from CVID diagnosis to GLILD detection was 7.8 years. Compared with matched control subjects, cases were more likely to have a history of autoimmune cytopenia, hypersplenism, polyarthritis, lower marginal zone and switched memory B cells, and restrictive lung function. Multivariate analysis revealed that hypersplenism (odds ratio [OR], 24; 95% confidence interval [CI], 4.5-179.1), polyarthritis (OR, 19; 95% CI, 2.3-206.8), and percent predicted FVC (OR, 0.93; 95% CI, 0.87-0.98) were independently associated with the development of GLILD. The rate of change of percent predicted FVC (slope, P = 0.48) did not vary significantly in patients with GLILD over a mean follow-up of 7 years after diagnosis. CONCLUSIONS Hypersplenism and polyarthritis are strong risk factors for GLILD in patients with CVID. Percent predicted FVC remained stable over time in patients with GLILD.

Abstract
Patients with common variable immunodeficiency disorder (CVID) are subject to lymphoproliferative disorders and predisposed to lymphoma. Some patients may also develop liver lesions. The purpose of this study was to define clinical and histopathological features of patients with CVID presenting with liver lesions suspicious of lymphoma. Four CVID cases corresponding to these criteria were retrieved from our files. Liver biopsy specimens were subjected to morphologic, immunophenotypic and molecular analysis. All patients presented with hepatosplenomegaly and two furthermore with lymphadenopathy. The clinical working diagnosis in the four cases was lymphoma. All liver biopsies revealed nodular regenerative hyperplasia (NRH), associated with mild to marked sinusoid lymphocytic infiltrate consisting of "activated" cytotoxic T cells (CD8+, Tia1+, granzyme B+, TCRβF1+, CD56-). EBER was negative in all cases. T cell clonality was found in one of the two interpretable cases. All patients had an indolent course and clinical symptoms regressed with immunoglobulin replacement. This study suggests that indolent proliferation in the liver sinusoid of cytotoxic T cell associated with NRH is a specific liver lesion in the context of CVID. In CVID patients clinically suspected of lymphoma, pathologists should avoid a misdiagnosis of aggressive T cell lymphoma with a risk of over treatment.

Abstract
Background: Most of the hypogammaglobulinemic patients have a clinical history in favor of allergic respiratory disease. Nevertheless, in these patients the importance and prevalence of atopic disorders have not been completely explained. Objectives: This study was aimed to evaluate atopic manifestations (dermatitis, allergic rhinitis and asthma) and pulmonary function in patients with hypogammaglobulinemia. Patients and Methods: We used the international study of asthma and allergies in childhood (ISAAC) questionnaire in forty-five patients diagnosed with hypogammaglobulinemia and spirometry was done in 41 patients older than 5 years. Results: Spirometry results were normal in 21 (51%), and showed obstructive in 15 (37%) and restrictive pattern in 5 (12%) of the 41 patients who were evaluated. By the end of the study, asthma was diagnosed in nine (20%) patients and other atopies (rhinitis and dermatitis) identified in 10 (22%), and four (9%), respectively. Conclusions: Atopic conditions should be investigated in the hypogammaglobulinemic patients and the prevalence in these patients may be higher than in normal population. Also, it is recommended to perform a pulmonary function test as a routine procedure in patients with hypogammaglobulinemia and atopy should be assessed in these patients.

Abstract
BACKGROUND Issues of fertility and pregnancy place an extra burden on females with primary immunodeficiencies. Patients lack reliable information and providers lack guidelines to counsel patients on these anxiety-provoking matters. OBJECTIVE To collate concerns and experiences related to fertility and pregnancy from females with humoral immune deficiencies. METHODS We conducted an internet-based survey of female patients who self-identified as having a diagnosis of primary humoral immune deficiency. RESULTS Responses from 490 women with common variable immune deficiency and 100 with hypogammaglobulinemia were evaluated. The reported fertility measure (% of women who had had a birth) was statistically significantly lower as compared to the general US population (70 % vs. 85 %, p < 0.0001) whereas the rates of spontaneous pregnancy loss were comparable. This group reported a total of 966 pregnancies; 72 % resulted in a live birth. A majority of the pregnancies progressed with no incident and with continuation of their IgG replacement therapy; 23 % reported an increase in IgG dosing during pregnancy. Only 15 % of those reporting a first pregnancy indicated that they had been diagnosed with immune deficiency prior to their first pregnancy; these women expressed concern regarding the effect of immune deficiency on their fertility, pregnancy and decision to have children. CONCLUSION With inherent limitations of self-reported responses to surveys, females with humoral immune deficiencies reported relatively good rates of fertility and pregnancies ending in live births. Results of the survey will serve as peer support for patients and inform counseling guidelines for providers.

Abstract
BACKGROUND Persons with primary immune deficiency disorders (PID), especially those disorders affecting the B-cell system, are at substantially increased risk of paralytic poliomyelitis and can excrete poliovirus chronically. However, the risk of prolonged or chronic excretion is not well characterized in developing countries. We present a summary of a country study series on poliovirus excretion among PID cases. METHODS Cases with PID from participating institutions were enrolled during the first year and after obtaining informed consent were tested for polioviruses in stool samples. Those cases excreting poliovirus were followed on a monthly basis during the second year until 2 negative stool samples were obtained. RESULTS A total of 562 cases were enrolled in Bangladesh, China, Iran, Philippines, Russia, Sri Lanka, and Tunisia during 2008-2013. Of these, 17 (3%) shed poliovirus, including 2 cases with immunodeficient vaccine-derived poliovirus. Poliovirus was detected in a single sample from 5/17 (29%) cases. One case excreted for more than 6 months. None of the cases developed paralysis during the study period. CONCLUSIONS Chronic polioviruses excretion remains a rare event even among individuals with PID. Nevertheless, because these individuals were not paralyzed they would have been missed by current surveillance; therefore, surveillance for polioviruses among PID should be established.

Abstract
Common variable immune deficiency (CVID) is a heterogeneous disease associated with ineffective production of antibodies. It is usually diagnosed in adulthood, but a variable proportion of children develop CVID. Early identification of patients with potentially worse prognosis may help to avoid serious complications. The goal of this study was to associate the clinical phenotype of patients with early onset CVID with peripheral B-cell maturation profile. Four color flow cytometry was used to define distribution of peripheral B-cell subsets in 49 children with early-onset CVID. All clinical data were extracted from medical records. A proportion of patients demonstrated diminishing with time total B-lymphocytes pool, beyond physiological age-related changes. Irrespective from duration of the follow-up period the B-cell maturation profile in individual patients remained unchanged. We identified six different aberrant peripheral B cell maturation profiles associated with different clinical characteristics. Patients with an early B-cell maturation block earlier required replacement therapy and were at significantly greater risk of enteropathy, granuloma formation, cytopenia, and lymphoproliferation. B-cell maturation inhibited at the natural effector stage was associated with higher risk of autoimmune manifestations other than autoimmune cytopenia. Prevalence of male patients was observed among patients with B-cell maturation inhibited at naïve B-cell stage. In conclusion, the diagnostic process in patients with suspected early-onset CVID shall include routine analysis of peripheral B-cell maturation to provide surrogate markers identifying patients at greater risk of developing certain complications.

Abstract
B lymphocyte subpopulations, previously defined classification schemes (Freiburg, Paris, EuroClass), TNFRSF13B (TACI), TNFRSF13C (BAFF-R), TNFSF13 (APRIL) gene mutations, CTLA-4 and ICOS gene polymorphisms were analyzed in 25 common variable immunodeficiency (CVID) patients and 25 healthy controls. Patients were also divided into two subgroups due to some disease severity criteria. SG (severe disease group) (n:11) included patients who have splenomegaly and/or granulomatous diseases and/or bronchiectasis and/or lower baseline IgG values (<270 mg/dl). MG (moderate disease group) (n:14) patients diagnosed as having ESID/PAGID criteria but does not fulfill SG inclusion criteria. The onset of infectious symptoms and age at diagnosis were 50.0 ± 45.7 and 78.5 ± 54.5 months, respectively. Parental consanguinity rate was 54.5% in SG and 7.1% in MG. Switched-memory B cells (CD19 + 27 + IgD-IgM-) showed significant decrease in CVID patients and these cells were also significantly lower in SG compared to MG. CVID patients had significantly higher percentages of CD19 + κ + B cells and CD19 + λ + B cells than healthy controls. Freiburg classification: 87.5% of patients (n:21) were in group I and 12.5% were in Group II. Eighteen (75%) CVID patients with a low percentage of CD21(low) B cells were in Group Ib while three patients classified as Group Ia. The significantly lower levels of IgG and IgA in Group Ia is a novel finding. The percentages of patients for Paris Classification groups MB0, MB1, MB2 were 88%, 4% and 8%, respectively. There was a significant increase of splenomegaly, lymphadenopathy and autoimmune cytopenia in Group MB0. EuroClass: 45.8% of patients were smB+ and 54.2% were smB-. Splenomegaly and lymphadenopathy were significantly higher in smB- group. TACI: One patient carried heterozygous C104R mutation which was known as disease causing. APRIL: G67R and N96S SNPs were detected in most of the patients and healthy controls. BAFF-R: P21R/H159Y compound heterozygous mutation (n:1) and P21R heterozygous mutations (n:3) were detected. +49 A > G changes in exon 1 of CTLA-4 gene: GG and AG genotypes increase the risk of CVID development 1.32 and 2.18 fold, respectively. 1564 T > C polymorphisms on 3'UTR region in exon 2 of ICOS gene was not found to be significantly different in CVID patients. CVID classifications were not helpful in determining the genetic etiology of CVID.

Abstract
Common variable immunodeficiency is a primary immunodeficiency disease characterized by reduced serum immunoglobulins and heterogeneous clinical features. Recurrent pyogenic infections of upper and lower respiratory tracts are the main clinical manifestations of common variable immunodeficiency. Hemolytic uremic syndrome is a multisystemic disorder characterized by thrombocytopenia, microangiopathic hemolytic anemia, and organ ischemia due to platelet aggregation in the arterial microvasculature. This is one of the rare cases of patients diagnosed with common variable immunodeficiency, which was complicated by hemolytic uremic syndrome.

Abstract
BACKGROUND Multiple calcified primary central nervous system lymphoma (PCNSL) is extremely rare in childhood. METHODS We report a 4-year-old boy suffering from multiple calcified B-cell lymphoma in the brain with immunodeficiency. RESULTS The boy had a history of walking weakness and seizure for 4 months. The serum levels of immunoglobulin G, A and M were decreased. Brain MRI showed multiple lesions which had ring enhancement. CT showed calcification in all of the lesions. The boy was firstly misdiagnosed with multiple chronic brain abscesses. Pathological analysis of biopsy confirmed the diagnosis of anaplastic diffuse large B-cell lymphoma. CONCLUSION PCNSL should be included in the differential diagnosis of intracranial mass with calcification.

Abstract
INTRODUCTION More than 200 primary immunodeficiencies (PID) have been described and about 60% present during childhood. Early diagnosis and treatment have been shown to improve patient outcome. AIM Analysis of patients with a PID diagnosed in a paediatric tertiary care hospital-referral centre over a period of 10 years. PATIENTS AND METHODS Medical records of all paediatric patients followed up in our unit were retrospectively reviewed. Clinical and epidemiological features, laboratory tests, therapy and outcome were analysed. RESULTS One hundred and eighty nine patients were followed up in this period of time. Antibody disorders were the most common diagnosis. In our series, clinical presentation at diagnosis were: recurrent respiratory infections in selective IgA deficiency and common variable immunodeficiency (CVID) patients, failure to thrive and opportunistic infections (mainly viral infections) in patients with severe combined immunodeficiency (SCID), skin abscesses (Staphylococcus aureus, Serratia spp.) and complicated pneumonia (Aspergillus spp., Rhodococcus equi) in chronic granulomatous disease, congenital heart disease and consistent phenotype in 22q11 deletion syndrome, skin abscesses and ecthyma gangrenosum in severe congenital neutropenia and opportunistic infections and sepsis (Pseudomonas aeruginosa) in children with X-linked agammaglobulinaemia (XLA). Lymphoproliferative disorders were common in CVID. No malignancies were observed during this period. One patient with XLA developed chronic encephalitis. All patients with CVID and XLA were receiving immunoglobulin replacement therapy (8 intravenous and 14 (since 2006) subcutaneous route) and in all but two SCID patients, stem cell transplantation was performed. Outcome was good in most of them except 8 SCID (2 prior and 6 after transplantation), 3 Wiskott-Aldrich syndrome, 1 complete DiGeorge, 1 chronic granulomatous disease and 1 ataxia-telangiectasia patients who died during follow-up. CONCLUSION The vast majority of patients included in this series presented with typical clinical features; therefore, basic knowledge of these entities in primary care and collaboration with hospital referral centres should allow a large number of PID in children to be diagnosed at an early stage, leading to proper treatment and monitoring, and therefore improvement of patient prognosis.

Abstract
Given the complex immune function of the gastrointestinal (GI) tract, it is not surprising that many children with primary immunodeficiencies present with GI tract manifestations. Although many immunodeficiency disorders present with overt evidence of immune dysregulation, a few can present in older children with more subtle signs and symptoms. Such children may present first to a gastroenterologist with common symptoms, including malabsorption, diarrhea, hepatomegaly, or inflammatory bowel disease, which may actually be a manifestation of their underlying immune disorder. A thorough clinical history in combination with a careful review of histology from biopsies may reveal clues that one is dealing with a disease entity outside the norm and may prompt additional laboratory studies beyond the usual set of screening laboratory tests. Once the true underlying diagnosis is revealed, more appropriate therapy can be initiated. Additionally, more appropriate anticipatory guidance regarding the expected disease course, response to medications, and any additional risks that therapy may entail can be provided to the family.

Abstract
PURPOSE OF REVIEW The general pediatrician should be empowered to utilize continuity of care for the recognition of unusual or severe patterns of infection. With the burgeoning field of genetics, primary immune deficiencies (PIDs) can be diagnosed and treated earlier to provide better outcomes for patients and families. Improved treatment modalities have redefined expectations for many infants born with PIDs. RECENT FINDINGS The prevalence of PIDs increases as researchers discover novel immunodeficiency syndromes and as clinicians increasingly recognize and diagnose nuanced presentations of immunodeficiency. Novel immunodeficiency syndromes associated with mutations in DOCK8, CARD9, and PRKDC recently have been described. For the first time in the United States, newborns from an entire state were screened for lymphopenia, allowing potentially life-saving early diagnosis of the most severe forms of PID before the onset of symptoms. Hematopoietic stem cell transplantation (HSCT) and gene therapy continue to be evaluated as curative treatments with increasing success rates for some of the most severe PIDs. SUMMARY The field of PID continues to expand and advancements have been made in earlier diagnosis and screening. Comparative effectiveness research into treatment modalities offered to patients with PID is leading to a better understanding of optimal therapies for specific PIDs. In the meantime, the advocacy efforts of established and emerging PID networks promote excellence in clinical recognition and treatment of PIDs in children.

Abstract
Recent studies suggest that patients with common variable immunodeficiency (CVID) and low numbers of switched memory B cells have lower IgG levels and higher rates of autoimmune disease, splenomegaly, and granulomatous disease; however, no prior literature has focused exclusively on pediatric cases. We examined the relationship between switched memory B cells and clinical and immunologic manifestations of CVID in a pediatric population. Forty-five patients were evaluated. Patients were categorized as Group I (<5 switched memory B cells/ml, n = 24) or Group II (> or =5 switched memory B cells/mL, n = 21). CD3(+) T-cell counts and CD19(+) B-cell levels were lower among Group I patients. Only those in Group I had meningitis, sepsis, bronchiectasis, granulomatous lung disease, autoimmune cytopenias, or hematologic malignancies. Segregation of pediatric patients into high risk (Group I) and average risk (Group II) may assist in targeting surveillance appropriately.

Pediatr Allergy Immunol 2010: 21: 793-805. (c) 2009 John Wiley & Sons A/S Pulmonary complications are frequently observed in common variable immunodeficiency (CVID). We reviewed the literature related to radiologic imaging techniques and pulmonary function tests (PFT) for diagnosing pulmonary complications in CVID. Scientific publications related to CVID (or primary hypogammaglobulinemia), pulmonary complications, PFT, chest X-ray (CXR), and high-resolution computed tomography scan (HRCT) were detected in PubMed, Embase and in reference lists of selected articles. Twenty-six articles including 1047 patients (587 patients with CVID) were reviewed. Up to 73% of CVID patients develop chronic structural pulmonary complications, of which bronchiectasis and bronchial wall thickening are most frequently detected. HRCT is the most sensitive method for identification of structural abnormalities, detecting pulmonary complications that were missed on CXR and PFT in 2-59% of patients. On PFT, obstructive flow-volume curves were most commonly found, eventually occurring in 50-94% of patients. HRCT is an important diagnostic tool for pulmonary complications in CVID at the time of diagnosis and at regular time-points during follow-up, with the proper follow-up interval yet to be determined.

Abstract
Common variable immune deficiency is a heterogeneous immune deficiency characterized by reduced serum immunoglobulins and a lack of antibodies. As the name implies, B-cell defects are variably defective. In particular, peripheral blood isotype-switched CD27(+) memory B cells are reduced in number and have been the basis of several classification schemes. A lack of these B cells has been associated with selected clinical conditions, including immune cytopenias, splenomegaly, granulomatous disease and lymphadenopathy. Genetic defects in ICOS, CD19 and TACI have been described. In addition to defects in the production or survival of memory B cells, in most subjects, B cells have defects in Toll-like receptor signaling.

Abstract
BACKGROUND AND OBJECTIVE Lung damage is considered to be key to Common Variable Immunodeficiency (CVID) prognosis. We describe lung damage in pediatric CVID patients and assess its relationship with memory B cells (MB) phenotype, immunoglobulin G (IgG) levels at the time of diagnosis, and diagnostic delay. We also assessed the prevalence of allergy and autoimmune phenomena. PATIENTS AND METHOD Cross-sectional study of 17 CVID patients treated at Vall d'Hebron University Hospital. Prevalence ratio and prevalence odds ratio were used to assess the effect of MB cells phenotype, IgG levels and diagnostic delay on lung damage. RESULTS Five of seventeen patients presented bronchiectasis. Diagnostic delay >5 years was significantly associated with more severe lung damage. MBO phenotype and low IgG levels at the time of diagnosis showed a trend to more severe lung damage without reaching statistical signification. A higher prevalence of allergic or autoimmune phenomena was not observed. CONCLUSIONS Latter diagnosis is associated with greater lung damage in CVID patients. The study of MB cells should be included in the study of these patients.
