Int Arch Allergy Immunol. Certain patients with decreased helper T-cell activity have been described. Inability to train, recurrent infection, and selective IgM deficiency. Francisco Talavera, PharmD, PhD Adjunct Assistant Professor, University of Nebraska Medical Center College of Pharmacy; Editor-in-Chief, Medscape Drug ReferenceDisclosure: Received salary from Medscape for employment. Have a question? Al-Herz W, McGeady SJ, Gripp KW. Intern Med. Because this antibody helps provide protection against bacteria and viruses, having low IgM levels has been associated with a higher risk of recurring infections . In a retrospective study of a large allergy practice (20,000 patients) database, Goldstein et al reported prevalences of SIgM deficiency of 0.26% among adults and 0.03% among children. There is limited data regarding the prevalence of selective IgM deficiency (SIgMD) since there have not been any large-scale studies done. 2004. involving B- and T cells, and hypogammaglobulinemia are almost invariably present. One could speculate that failure to regenerate B-cell precursors could lead first to depletion of IgM, with gradual loss of IgG and other isotypes occurring later as class-switched memory B-cells and plasma cells fail to be replaced. Patients may develop prolonged or life-threatening infections caused by both encapsulated bacteria and viruses, especially in infancy. The mean concentration of serum IgG4 was not different from healthy controls.116 Lin and coworkers reported that serum concentration of IgG subclasses in SLE varies with elevation of IgG1, IgG2, and IgG3 and normal in IgG4. Gupta S, Gupta A. 8:1056. Resistance was restored by transfer of IgM from unimmunized mice, indicating a role for natural IgM. [Medline]. Several mechanisms have been proposed by which IFN-α contributes to autoimmunity including its effect on B cells. Clin Immunol Immunopathol. SLE itself is typified by high levels of serum immunoglobulins and circulating autoantibodies. Whether a person has primary or secondary SIgMD (associated with another underlying condition) also plays a role in the types of symptoms a person has, as they may also have symptoms of their underlying condition. [8] Cell-mediated immunity appears to be intact, but an insufficient number of detailed studies are available to confirm this. https://profreg.medscape.com/px/getpracticeprofile.do?method=getProfessionalProfile&urlCache=aHR0cHM6Ly9lbWVkaWNpbmUubWVkc2NhcGUuY29tL2FydGljbGUvMTM3NjkzLW92ZXJ2aWV3. placeholder for the horizontal scroll slider, Office of Rare Disease Research Facebook Page, Office of Rare Disease Research on Twitter, U.S. Department of Health & Human Services, Caring for Your Patient with a Rare Disease, Preguntas Más Frecuentes Sobre Enfermedades Raras, Como Encontrar un Especialista en su Enfermedad, Consejos Para una Condición no Diagnosticada, Consejos Para Obtener Ayuda Financiera Para Una Enfermedad, Preguntas Más Frecuentes Sobre los Trastornos Cromosómicos. Kung SJ, Gripp KW, Stephan MJ, Fairchok MP, McGeady SJ. CVID should be suspected in SLE patients with quiescent disease activity and not on immunosuppressive treatment but with recurrent sinopulmonary infections.112,128,132,134 Table 46.11 lists Ig abnormalities and their association with SLE. Clinical manifestations depend on the type of specific defect. SLE or lupus-like manifestations have been detected in 93% of homozygous C1q-deficient, 75% of C4-deficient, 57% of C1r/C1s deficient, and 20-32% of C2-deficient individuals.13,14,16 Yet, although complement deficiencies have contributed to new concepts on the mechanisms of SLE pathogenesis, the prevalence of homozygous deficiencies is currently estimated at less than 1% of SLE patients. Clin Exp Nephrol. Infants can present with severe and overwhelming infections. 2014 Apr. Patients with SIgM deficiency are susceptible to recurrent sepsis and overwhelming infection with encapsulated bacteria (eg, Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae). To date, eight primary immunodeficiency diseases have been described in the horse. 2009. The serum titers of IgG1 anti-dsDNA and IgG2 anti-nucleohistone have been noted to rise before a renal relapse and were the predominant subclasses in the serum in patients with active nephritis. Immunoglobulin M deficiency may be detected early, but immunoglobulin G deficiency becomes manifest only after the age of 3 months when the maternal supply has been exhausted. Increased regulatory T-cell activity specific for IgM has been described. Some affected dogs, like human patients with IgA deficiency, have a predisposition to developing atopic disease. Survival half-life of IgG in SLE patients is decreased at an average of 8.2 days compared with 18 days in normal controls with an average of 10.1% of total body IgG catabolized daily compared with a mean of 3.9% in normal controls.115. 1986. Hong R, Gupta S. Selective immunoglobulin M deficiency in an adult with Streptococcus pneumoniae sepsis and invasive aspergillosis. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Srividya Sridhara, MD Resident Physician, Department of Internal Medicine, University of OklahomaDisclosure: Nothing to disclose. If you do not want your question posted, please let us know. Affected patients display a profound impairment of T-cell function with varying degrees of B-cell dysfunction, which can be evidenced by relatively simple laboratory tests; lymphopenia (usually <500 total lymphocytes/mm3) involving B- and T cells, and hypogammaglobulinemia are almost invariably present. 42:961-2. Selective IgA deficiency is the most common of the primary immunodeficiencies with a frequency ranging from 0.03% to 0.25% in patients who are hospitalized or in clinics and 0.1% in the general community. [1] [2] IgM is the first antibody the immune system makes to fight a new infection. 2000. Clin J Sport Med. Gradually, current state-of-the-art laboratory technology is being applied in studying patients with SIgM deficiency, though much remains to be learned. The underlying cause of selective IgM deficiency (SIgMD) is not yet known. Some patients are asymptomatic. Diseases & Conditions, 2001 Herrod, HG. About 14% of reported cases of selective IgM deficiency have autoimmune conditions, including SLE.122,123, IgA, the second most abundant Ig, exists in two isotypes (IgA1 and IgA2) with IgA1 as the predominant isotype in the serum. Selective partial IgM deficiency: Functional assessment of T and B lymphocytes in vitro. 1971 Feb. 47(2):399-404. A case of IgM deficiency with B cell deficiency detected by ABO discrepancy in a patient with acute osteomyelitis. The frequency varies in different populations. 137693-overview for: Medscape. 57(1):99-105. In Handbook of Vertebrate Immunology, 1998. The serum titers of IgG1 anti-dsDNA and IgG2 antinucleohistone have been noted to rise before a renal relapse and were the predominant subclasses in the serum in patients with active nephritis. 109:581-91. The most common forms are selective IgM deficiency and selective IgA deficiency, characterized by a serum level of IgM or IgA, respectively, that is at least two standard deviations below normal. Natural IgM (but not IgG) antibodies against several viruses and L. monocytogenes were found to be present in the serum of unimmunized mice (Ochsenbein et al., 1999). Louis AG, Gupta S. Primary selective IgM deficiency: an ignored immunodeficiency. [Full Text]. Longitudinal studies are needed to determine whether total serum IgE concentration and IgE anti-dsDNA are useful in monitoring lupus disease activity. Clin Dev Immunol. J Investig Allergol Clin Immunol. Once a diagnosis of immunodeficiency is suspected, testing should be performed to classify the disease. In horses there are distinct forms of selective IgM deficiency with most affected animals succumbing to septicemia or pneumonia by 10 months of age. Over 80% of IgM-deficient patients present with recurrent infections, usually in the respiratory tract.

Jul 2007. The serum IgM concentration can be decreased, especially in SLE patients of long disease duration, and tends to be related to disease activity. Gul U, Soylu S, Yavuzer R. Epidermodysplasia verruciformis associated with isolated IgM deficiency. Unlike other Ig isotypes, IgM concentration peaks at 20 to 40 years of life and reaches a plateau at 50 years. 62(6):547-52. It is theorized that excessive T-cell suppressor and decreased B-cell activity characterized this subset. [Medline]. [Medline]. Serum immunoglobulin levels are controlled by intricate immunological regulatory mechanisms, and heterogeneity is believed to exist in the pathogenesis of SIgM deficiency. Forms of these diseases have been identified and described in horses and dogs. May 21, 2020. [5] The levels of other immunoglobulin classes are within reference ranges. Cross-sectional study showed IgE levels correlated inversely with disease activity. The serum concentration of IgG subclasses in SLE varies with the elevation of IgG1, IgG2 and IgG3, and normal IgG4.
