Renal Evaluation in Common Variable Immunodeficiency

Metrics details. Common variable immunodeficiency disorders CVID are a group of rare innate disorders characterized by specific antibody deficiency and increased rates of infections, comorbidities and mortality. We performed a retrospective analysis of the European Society for Immunodeficiencies ESID registry data on the subset of patients classified by their immunologist as CVID and treated between and These outcomes were expressed as a rate per 10 5 of the CVID cohort the individual disease burden , and of the general population the societal disease burden. Data of patients from 23 countries were analysed. Annual comorbidity rates: bronchiectasis, While the societal burden of CVID may seem moderate, it is severe to the individual patient. Delay in CVID diagnosis may constitute a modifiable risk factor of serious comorbidities and death but showed no improvement. Tools supporting timely CVID diagnosis should be developed with high priority.

Objectives: Common variable immunodeficiency CVID is a primary humoral immunodeficiency characterised by reduced serum levels of immunoglobulins, recurrent infections, autoimmune phenomena and lymphoproliferative disorders. Gastrointestinal symptoms are very common in these patients and a coeliac-like villous atrophy was described in some of them.

Since mortality in CVID is much higher than in the general population, our aim was to evaluate mortality rates and clinical predictors of survival in patients with both CVID and duodenal villous atrophy. Univariate analysis for each predictor was conducted and Kaplan-Meier curves were generated to evaluate survival. Mortality was higher in men compared to women 60 vs.

Common variable immunodeficiency CVID comprises a heterogeneous group of disorders characterized by impaired antibody production. Kidney involvement in CVID is described in isolated and sporadic case reports. The objective of this study was to study the renal function pattern in CVID patients through glomerular and tubular function tests. Study of 12 patients with CVID diagnosis and 12 healthy control individuals. Glomerular filtration rate GFR , fractional excretion of sodium and potassium , urinary concentration, and acidification capacity were measured.

In addition, microalbuminuria and urinary monocyte chemoattractant protein-1 MCP-1 were evaluated as markers of selectivity of the glomerular barrier and inflammation, respectively. Also, while all control subjects achieved a urinary pH less than 5. Patients showed a trend towards an elevated prevalence of tubular dysfunction, mainly related to urinary acidification and concentration capacities. Common variable immunodeficiency CVID comprises a heterogeneous group of disorders characterized by impaired antibody provision.

Clinically, CVID is characterized by susceptibility to recurrent infections and various sequelae and complications, including bronchiectasis, autoimmunity, enteropathy, splenomegaly, granulomatous inflammation, lymphoproliferation, and malignancy [ 2 ]. Kidney involvement in CVID has been described only sporadically in isolated case reports. Renal granuloma [ 3 — 5 ], focal segmental glomerulosclerosis [ 6 ], membranoproliferative glomerulonephritis [ 6 ], renal amyloidosis [ 7 ], and end-stage renal disease have all been described in CVID patients.

However, it is not possible to ascertain whether all these kidney-associated clinical manifestations are directly related to CVID or only coincidental associations.

Why Is CVID Referred to as “Common. Variable” in people who have the same disorder. Why Does diagnose CVID base it on the date.

Full Issue PDF. Perm J ; Introduction: Multiple myeloma MM is a clonal plasma cell disorder commonly associated with secondary immune deficiency. Besides a defective immune system and susceptibility to infections, CVID is associated with autoimmune disorders, gastrointestinal tract inflammation, granulomatous disease, and malignancies. Although MM and CVID both manifest an abnormal immune system homeostasis, the pathogenesis of the immune defect is distinctly different: Quantitative deficiency of the normal plasma cells in the former and qualitative defect in plasma cell maturation in the latter.

Patients with MM who have an unusually high burden of infections and profound immune deficit persisting even after successful myeloma therapy merit recognition as a distinct cohort that warrants heightened attention from clinicians and scientists.

The survival of people with CVID improved from about 30% 12 years after For numerical data, such as year of birth, visit date and Ig dose.

Onset of symptoms can occur from early childhood to the eighth decade or later 2. Current estimates suggest a prevalence between 1: 25 to 1: in Caucasians 3 , 4. For reasons that are unclear, CVID appears to be less frequent in Asian and African populations, although there may be ascertainment bias. The majority of patients with CVID present with recurrent and severe infections.

Untreated, patients are predisposed to chronic suppuration of the respiratory tract, often resulting in chronic sinus disease and bronchiectasis. There is also an increased risk of malignancy 6. There is no single clinical feature or laboratory test, which is pathognomonic for CVID. The identification of CVID therefore relies on diagnostic criteria.

There are currently three new sets of diagnostic criteria for CVID 7 — 9. The Ameratunga et al. The revised European Society for immunodeficiencies 8 are similar to the Ameratunga et al. The most recent International Consensus Document 9 CVID criteria claim to be able to make a definite diagnosis on the basis of a single abnormal vaccine challenge result in a patient with primary hypogammaglobulinemia 9. The latter two criteria have set the threshold for IgG at 2 sd below the mean.

The immunoglobulin levels are also required to be repeated in these latter criteria.

Common Variable Immunodeficiency Disorders (CVID) are the most 4 years although some patients have symptoms dating back to infancy.

Professional Reference articles are designed for health professionals to use. You may find one of our health articles more useful. Common variable immunodeficiency CVID is the most common symptomatic primary immune deficiency in adults. It is often diagnosed late when there is less scope to prevent complications. CVID is an umbrella diagnosis in that it encompasses a group of genetic disorders which result primarily in hypogammaglobulinaemia or failure of antibody production.

Patients typically present with recurrent infections, particularly of the respiratory tract.

Morbidity and mortality in common variable immune deficiency over 4 decades

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.

In spite of major progress in the last decade, the genetic basis of CVID is unknown in most patients. If a causative defect is identified, these patients are removed from the umbrella diagnosis of CVID and are reclassified as having a CVID-like disorder caused by a specific mutation.

Common Variable Immune Deficiency (CVID) is the most frequent triggers, but limited research has been completed to date [4] [5][6]. Accounting for the prevalence of CVID in Europe, estimated at 1 in 25, people [5, 6].

Study record managers: refer to the Data Element Definitions if submitting registration or results information. This study will determine whether people with common variable immunodeficiency CVID with and without gastrointestinal GI symptoms have gut abnormalities inflammation or loss of function and changes in immune system cells and chemicals in the blood and gut.

Patients have sinus, lung and other infections, and many also have stomach and intestinal problems, such as chronic diarrhea, inability to absorb nutrition from food, and intestinal infections caused by bacteria. CVID patients with gastrointestinal symptoms 10 years of age and older may be eligible for this study; CVID patients without gastrointestinal symptoms 18 years of age and older will be enrolled as control subjects.

Candidates will be screened with a review of their medical records, a medical history and physical examination, HIV blood test, stool sample, and hydrogen breath test. The breath test measures the amount of hydrogen in the breath after drinking sugar water, showing the digestive effects of bacteria in the upper intestine. Participants will be admitted to the NIH Clinical Center for several days to undergo the following procedures:.

Identification of GI abnormalities associated with changes in immune response in CVID patients will help in developing and testing new treatments for this disease. In addition to chronic or recurrent sinopulmonary infections, many patients develop gastrointestinal manifestations that can be disabling or fatal. Data suggest that these gut abnormalities have a primary immune basis, implicating T cells primarily, and are not related to the infectious complications of CVID.

Currently there is no standard therapy for the associated gastrointestinal disease outside of empiric nutritional intervention for weight loss and non-specific anti-diarrheal agents. In addition there is no data about the prevalence of gastrointestinal abnormalities in CVID patients who have no overt gastrointestinal symptoms. The objectives of this study are to characterize the gastrointestinal abnormalities that occur in CVID patients and correlate this with the immunophenotype and cytokine secretion of peripheral blood and lamina propria lymphocytes and monocytes.

Bronchiectasis in Common Variable Immunodeficiency

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.

Leaky intestines may cripple bacteria-fighting immune cells in patients with a rare hereditary disease, according to a study by researchers in Lausanne, Switzerland. The study, published in The Journal of Experimental Medicine , may explain why these patients suffer from recurrent bacterial infections. Patients with a disease called common variable immunodeficiency CVID suffer from recurrent bacterial infections as a result of faulty immune cells.

But despite these immune defects, CVID patients rarely contract viral infections. New data from Matthieu Perreau and colleagues in Lausanne now show that bacteria-fighting T cells in the blood of these patients showed signs of exhaustion evident by their expression of an inhibitory protein called PD-1 , but virus-fighting T cells were unscathed. T cell exhaustion in the patients was associated with increased gut bacteria in the bloodstream, possibly due to the lack of protective antibodies that normally clear these wayward bugs.

As a result, bacteria-specific T cells may be repetitively stimulated, a scenario known to trigger exhaustion. The data suggest that “immunotherapy” strategies aimed at perking up T cells — already in use in cancer patients — may protect CVID patients against recurrent bacterial infection.

Marvellous progress — well done! They have identified the gene independently in a New Zealand family. For the individual New Zealand family concerned, this has very significant implications. For those affected family members it presents the possibility of earlier diagnosis and so treatment options can be deployed earlier, before primary immunodeficiency disorders advance to the stage of causing significant organ damage. It also means that they have the opportunity to undertake pre-implantation genetic diagnosis so avoid the gene presenting in future generations of their direct descendants.
