Common Variable Immunodeficiency

Common variable immunodeficiency CVID is the most prevalent symptomatic primary immunodeficiency and comprises a group of disorders with similar antibody deficiency but a myriad of different etiologies, most of which remain undefined. The variable aspect of CVID refers to the approximately half of patients who develop non-infectious complications in addition to heightened susceptibility to infection.

The pathogenesis of these complications is poorly understood and somewhat counterintuitive because these patients that are defined by their immune futility simultaneously have elevated propensity for autoimmune disease. There are numerous aspects of immune dysregulation associated with autoimmunity in CVID that have only begun to be studied. These findings include elevations of T helper type 1 and follicular helper T cells and B cells expressing low levels of CD21 as well as reciprocal decreases in regulatory T cells and isotype-switched memory B cells.

Recently, advances in genomics have furthered our understanding of the fundamental biology underlying autoimmunity in CVID and led to precision therapeutic approaches. However, these genetic etiologies are also associated with clinical heterogeneity and incomplete penetrance, highlighting the fact that continued research efforts remain necessary to optimize treatment. Additional factors, such as commensal microbial dysbiosis, remain to be better elucidated.

Thus, while recent advances in our understanding of CVID-associated autoimmunity have been exciting and substantial, these current scientific advances must now serve as building blocks for the next stages of discovery. The term common variable immunodeficiency was originally used to describe patients with a primary antibody deficiency who did not meet criteria for the more well-defined PIDs such as Burton's agammaglobulinemia 3.

We have come to appreciate that CVID is best understood to constitute a group of hypogammaglobulinemic disorders with heterogeneous phenotypic presentations, rather than a single entity 4. The application of genomics has only furthered the evidence of heterogeneity within CVID.

The International Consensus Document on CVID put forward in agreed on a definition requiring IgG levels two standard deviations below the age-appropriate reference as well as either low IgA or IgM levels, and poor antibody response to vaccination in an individual that is at least 4 years old with no secondary cause of hypogammaglobulinemia 1. The European Society of Immune Deficiencies ESID diagnostic criteria differ slightly from these criteria in that they require the presence of symptoms such as infections or autoimmune manifestations, in addition to the laboratory abnormalities cited above, to make the diagnosis of CVID 5.

Notably, non-infectious presentations are an under-recognized feature of CVID and often the predominant clinical presentation, resulting in diagnostic delays of several years in many cases 6. While historically the clinical presentation of CVID was focused on the susceptibility to infections, the decision to include autoimmune and inflammatory conditions as primary clinical presentations reflects the heterogeneity of CVID and highlights the importance of recognizing these non-infectious entities as a feature of this immune deficiency.

Immunoglobulin replacement therapy is the standard of care for CVID. The improved survival in CVID patients has been attributed to the reduction of infectious complications thanks to the widespread use of immunoglobulin replacement and improved anti-microbial therapies 9 — While overall survival has improved, patients with CVID continue to have reduced survival compared to age-matched controls When comparing mortality within CVID patients, subjects with at least one non-infectious complication had significantly higher mortality compared to patients with only infectious complications 13 , These non-infectious complications including autoimmune, gastrointestinal, pulmonary, lymphoproliferative, and malignant complications 1 , are not ameliorated by immunoglobulin replacement therapy alone.

The clear necessity to address non-infectious complications of CVID has led to attempts at categorizing these heterogeneous disorders into distinct phenotypes, with the hopes of elucidating endotypes. The ultimate goal of such stratification of CVID is to identify targeted treatments that will improve outcomes in CVID patients with non-infectious complications 14 — They identified five distinct phenotypes: no complications, autoimmunity, polyclonal lymphocytic infiltration, enteropathy, and lymphoid malignancy Studies that followed have confirmed categorization of CVID based upon the presence of complications, with certain features like autoimmunity, lymphocytic interstitial lung disease, and lymphoid hyperplasia typically occurring together 6 , Assuming that CVID endotypes present within these phenotypic clusters, the pathogenesis and genetic mechanisms underlying the disease may be related.

Autoimmunity and immune deficiency have been shown to have genetic overlap and occur together beyond CVID 18 — 20 , suggesting a common pathophysiologic mechanism underlying both forms of immune dysregulation. In this review, we focus on one aspect of immune dysregulation, the autoimmune manifestations of CVID, providing an overview of these complications as well as an update on research and treatment advances.

The initial clustering of CVID patients with autoimmunity included organ specific autoimmune disease e. Further analysis on two other cohorts showed that within the autoimmune cluster, only autoimmune cytopenias had decreased survival and that organ-specific and systemic autoimmune disease showed no association with cytopenias or the other clinical phenotypes This led to a revision of the clinical phenotypes with more emphasis being placed on autoimmune cytopenias as opposed to autoimmunity in general Unbiased network clustering in a separate CVID cohort yielded similar phenotypes, with systemic and organ-specific autoimmune diseases clustering separately from autoimmune cytopenias While this distinction likely carries implications regarding underlying pathophysiology, many studies continue to combine autoimmune cytopenias with other autoimmunity as they compare CVID patients.

For this reason, we will make distinctions between autoimmune cytopenias and organ specific or systemic autoimmunity in this review.

Among autoimmune cytopenias, autoimmune thrombocytopenia and autoimmune hemolytic anemia occur most frequently, either separately or concurrently as Evan's syndrome. Autoimmune neutropenia also occurs in CVID, although more rarely than thrombocytopenia or anemia 9 , Autoimmune cytopenias are often associated with other non-infectious complications in CVID. Conversely, CVID patients with autoimmune cytopenias had a higher frequency of CVID-associated non-infectious complications, including granulomatous and lymphoproliferative disease, as well as organ-specific autoimmune disease, but interestingly, not systemic autoimmunity Splenomegaly was also more common in patients with autoimmune cytopenias and was found to share some immunophenotypic characteristics, but the pathophysiology of this link is still not clearly understood Though autoimmune cytopenias are highly associated with CVID, other forms of autoimmunity have also been frequently reported.

Although the male-to-female ratio was almost equal for overall autoimmune complications, there was a clear female predominance for the rheumatologic manifestations Several other studies have shown a similar female predominance for systemic autoimmune complications in CVID 29 , Other rheumatologic manifestations include systemic lupus erythematosus, Sjogren's disease, Behcet's disease, and psoriasis 24 , Among organ specific autoimmune manifestations, hypothyroidism was the most prevalent at 3.

Autoimmunity may also underlie gastrointestinal complications of CVID, including inflammatory bowel disease, autoimmune enteropathy, and autoimmune gastritis This finding highlights the importance of T cell dysfunction in CVID autoimmunity and demonstrates that pathogenesis of this immune disorder extends beyond defects of B cells exclusively.

Indeed, CVID patients with autoimmunity have been found to have lower total T cells compared to those without autoimmunity When Chapel et al. Overall, T cell-mediated processes that help promote immune tolerance appear to break down in a subset of CVID patients, contributing to the development of autoimmunity. T FH cells provide help to activate and diversify B cell responses within secondary and tertiary lymphoid tissues While T FH provide most of their function within germinal centers, it is notable that their increase is associated with germinal center enlargement and disorganization in CVID patients with autoimmunity This increased T FH development has been linked with greater IgA deficiency and resultant endotoxemia, presumably due to bacterial translocation from mucosal surfaces in the absence of IgA Thus, it is clear that T cell dysregulation, particularly loss of regulatory subsets with concurrent increase in proinflammatory lymphocytes, is a fundamental feature of CVID patients with autoimmunity.

Continued efforts toward improved understanding of this form of immune dysregulation will be vital to improving treatment of CVID associated autoimmune disease. Subsequent studies found increased proportions of CD21 low B cells in patients with CVID 37 , 51 , 52 , with clustering of these low levels in patients with autoimmunity 28 , These cells were found to have preferential homing to peripheral tissues such as the synovial fluid of rheumatoid arthritis patients and the bronchoalveolar space of CVID patients Further analysis found that CD21 low B cells from both rheumatoid arthritis and CVID patients expressed germline autoreactive antibodies which recognized nuclear and cytoplasmic structures Along these lines, CVID patients with autoimmunity have been found to have higher levels of IgM compared with non-autoimmune phenotypes 31 , While this may be a marker for increased risk of autoimmune disease, and may be related to the aforementioned CD21 low B cells, there may be a pathogenic role for IgM autoantibodies, as IgM may underlie the autoimmune cytopenias that are the predominant autoimmune manifestation of CVID B cell receptor diversity is diminished in CVID patients with autoimmunity As a consequence of this diminished B cell repertoire, the presence of certain B cell receptors with autoreactive proclivity, such as those that express the VH heavy chain, may be more prominent in CVID patients as has been demonstrated in other forms of PID associated with autoimmunity 60 , Thus, B cell developmental defects that impair immunity may also contribute to the propensity for autoimmunity in some CVID patients.

B cell-activating factor BAFF , a cytokine that promotes both maturation and survival of B cells, has long been linked with autoimmunity when its levels are elevated 62 — One possible explanation for this discrepancy is that the sample size of this cohort did not provide enough power to reach significance only 17 of 77 patients had autoimmunity.

In a separate study, BAFF levels were elevated in CVID patients with active interstitial lung disease, an inflammatory pulmonary disease linked with autoimmune cytopenias 17 , On the other hand, BAFF levels were not elevated in those with quiescent stable disease, suggesting that increases of this cytokine might be closely tied to disease activity 67 thus offering another possible explanation for the lack of association in the aforementioned cohort.

Other biomarkers of immune dysregulation have been linked with autoimmunity, as well as other non-infectious complications, in CVID. Importantly, an elevated T H1 signature has been found in the peripheral blood of these patients This heightened T H1 signature in the blood is consistent with the heighted T H1 cellular response previously mentioned to be increased in CVID patients with autoimmune complications and elevated CD21 low B cells.

Thus, systemic immune dysregulation favoring T H1 cytokine production appears to be an important feature of CVID patients with non-infectious complications, yet the pathological basis of this skewed cytokine response remains unclear. Likewise, the therapeutic benefit of trying to neutralize this heightened T H1 response remains inadequately explored Figure 1. Figure 1. On the other hand, memory B-cells, and B-cell receptor diversity are decreased.

Disturbance of T-cell homeostasis, with a decrease in T regulatory cells T R and a skew toward type 1 immunity, has been associated with autoimmunity in CVID. As CVID is a phenotypically heterogeneous disease, the expansive genetic landscape of these patients is perhaps unsurprising.

The majority of identified monogenic mutations encode proteins present in immune cells, which may reflect the nature of this immune disorder or a bias of the genomic analysis that is still nascent in its sophistication 77 , It is worth noting that while these mutations are associated with a clinical presentation that fits the diagnosis of CVID, many instances may not meet the full diagnostic criteria, in particular the extent of hypogammaglobulinemia typically needed.

As these mutations were described in patients with CVID or CVID-like disorders and are likely to be encountered in a clinical evaluation of such patients, we include them in our discussion of CVID-associated autoimmunity even though there is an emerging trend to categorize them separately. Heterozygous TACI mutations may be more appropriately defined as a risk factor for CVID, as some are not adequately rare to be considered monogenic etiologies and are frequently found in unaffected individuals It has been hypothesized that this difference may be due to the level of dysfunction in the TACI receptor: by regulating the function of several other receptors, TACI may be involved in central B cell tolerance and that reduced function results in loss of tolerance and resultant autoimmunity.

By contrast, in homozygous individuals, the complete loss of TACI function results in the inability to maintain continuous autoantibody production that would otherwise result in autoimmunity LRBA lipopolysaccharide-responsive beige-like anchor and CTLA-4 cytotoxic T-lymphocyte-associated protein 4 deficiencies are two closely related protein deficiencies that were detected in patients with CVID and autoimmunity While mutations in LRBA and CTLA4 have phenotypic variance thought to be due to incomplete penetrance and epigenetic changes, a common finding in these patients is hypogammaglobulinemia and early onset severe autoimmunity CTLA-4 is an inhibitory T cell receptor that negatively regulates immunity by inhibiting excessive T cell activation and maintaining immune tolerance via its effect on T R cells LRBA, on the other hand, is thought to play a role in CTLA-4 cell surface expression, hence the phenotypic similarities in the two deficiencies Deficiencies in both these proteins thus cause excessive T cell activation and breakdown of immune tolerance, resulting in autoimmunity.

They are both examples of how T cell-intrinsic genetic defects can lead to hypogammaglobulinemia, further highlighting how T cell dysfunction is key to the pathogenesis of at least some cases of CVID. One mechanism through which STAT3 is thought to lead to autoimmunity is by promoting the activation and expansion of autoimmunity-associated T H17 cells 47 , Additionally, increased STAT3 activation may impair B cell differentiation 87 leading to hypogammaglobulinemia and heightened autoreactivity found in association with CVID or more mild forms of hypogammaglobulinemia.

Class IA phosphoinositide 3-kinases PI3Ks are heterodimeric lipid kinases that are involved in regulating cell growth, survival, and activity. It is also a fundamental transcription factor for cytokine production by innate immune cells as well as other vital cell signaling pathways that expand beyond the immune system NFKB1 mutation has also been linked with cytokine dysregulation, namely the elevation of type 1 cytokines that mirrors the immune profile characterizing the broader population of genetically-undefined CVID with non-infectious complications Some with NFKB1 mutations have antibody deficiency without associated non-infectious complications NFKB2 mutations lead to autoimmunity affecting the skin, hair and nails, such as alopecia and trachyonychia, and less frequently autoimmune cytopenias, and are characterized by pituitary hormone deficiencies 99 Table 1.

The majority of cases may be polygenic, or perhaps better defined as simply multifactorial, with environmental, epigenetic, or other factors contributing. Over the past decade, the microbiome has been implicated in the manifestation of immune dysregulation , and has been explored in the pathogenesis of CVID complications It has been hypothesized that impaired immunity results in increased microbial translocation across the gut barrier. This in turn drives persistent systemic immune activation leading to the disruption of the immune homeostasis 46 , , While regular immune sampling and microbial translocation occur in healthy individuals , the increased frequency occurring in CVID patients with diminished barrier function may lead to both local and systemic inflammation and immune dysregulation.

Common variable immunodeficiency CVID is an immunodeficiency problem that causes a child to have a low level of antibodies and a decreased responsiveness to some vaccines. The child then becomes sick with infections that keep coming back. Most people with CVID become sick and are diagnosed as adults. But in some cases, the disease may become obvious after a child is 2 years old, during childhood or puberty. The symptoms of the disease are very different for each child affected.

Common variable immune deficiency CVID is a primary immunodeficiency disease, characterized by hypogammaglobulinemia, recurrent infections and various complications. The clinical heterogeneity of CVID has hindered identification of an underlying immune defect; diagnosis relies on clinical judgement, alongside evidence-based criteria. The lack of pathognomonic clinical or laboratory features leads to average diagnostic delays of 5 years or more from the onset.

Current criteria do not allow CVID to be diagnosed before 4 years although some patients have symptoms dating back to infancy. Most patients experience recurrent or severe bacterial infections and less commonly autoimmunity as a result of CVID. Some patients present with a sarcoidosis-like disorder or enteritis 2 , 3. A proportion of patients with CVID have a prominent T cell defect leading to severe viral or opportunistic infections.
