CVID has been rarely described in SLE patients after treatment has been initiated, which renders the diagnosis of CVID difficult because other causes of hypogammaglobulinemia need to be excluded. Low levels of IgM occur in multiple myeloma and some types of leukemia. In general, disease severity correlates with the loss of ADA activity; in children with neonatal or infant-onset SCID, its residual activity is 0–0.1% of normal, and in subjects with delayed or later onset, 1–5% of control activity is found (118). Whether this mechanism is relevant to human SLE remains to be established.79, Francisco P. On the other hand, all four IgG subclasses were detected in the renal glomerular deposits.118. Total serum IgG levels have no correlation with age, sex, race, or duration of disease. Under the rubric of circumstantial evidence, the importance of IgM suggested by the confluence of relevant features: high avidity, high agglutination capacity, presence in serum and mucosal surfaces in unimmunized animals, efficient complement activation, occurrence of three different Fc receptors, response to both thymus-independent and thymus-dependent antigens, and the existence of IgM memory B cells. [Medline]. The serum concentration of IgG subclasses in SLE varies with the elevation of IgG1, IgG2 and IgG3, and normal IgG4. /viewarticle/932671
A registry supports research by collecting of information about patients that share something in common, such as being diagnosed with Selective IgM deficiency. CVID should be suspected in patients with SLE with quiescent disease activity and not on immunosuppressive treatment but with recurrent sinopulmonary infections.62,73,76 Table 43-4 lists immunoglobulin abnormalities and their association with SLE. Most, but not all, patients have normal T cell numbers and function.219 The clinical history should be explored for the presence of associated conditions, as these may ultimately explain the low levels of IgM.
Unlike other immunoglobulin isotypes, IgM concentration peaks at 20 to 40 years of life and reaches a plateau at 50 years. People with SIgMD who experience new or different symptoms should be evaluated for an associated underlying disease or condition. 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.
sarcoma,217 lymphoma,205 and plasmacytoma have also been reported, but studies with larger samples are required to determine whether selective IgM deficient patients are really at risk of a malignancy (Goldstein et al., 2006).212.

Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. May 22, 2020, NCATS Translational Approach Addresses COVID-19 J Allergy Clin Immunol.
Int Arch Allergy Immunol. Low levels of lgM can be caused by multiple myelomo, some types of leukemia, and some inherited types of immune diseases. 161(1):91-96. In the Chinese population the frequency of selective IgA deficiency is 30-fold higher in SLE patients compared with the general Chinese population.127, Selective IgA deficiency is associated with major histocompatibility complex (MHC) region (HLA-B8, DR3, and DQ haplotype). Serum IgM levels in SLE have been reported to be increased during the early stages and during periods of disease activity. Arahata M, Tajiri K, Nomoto K, Tsuneyama K, Minami S, Shimizu Y. [Medline]. 149(3):283-288. [10, 11, 12] They may also have autoimmune disease including glomerulonephritis and osteomyelitis from which organisms are not recoverable, The most common presentation affects foals, and is associated with severe infections invariably leading to death before 10 months of age. It is theorized that excessive T-cell suppressor and decreased B-cell activity characterized this subset. Common variable immunodeficiency (CVID) is a heterogeneous syndrome of primary immunodeficiency marked by the failure of antibody production. The 'low', 'normal' and 'high' ranges vary with age, and are also lab-specific. Lim SH, Zhang Y, Wang Z, et al. Serum concentrations of other classes of immunoglobulin are normal, and B lymphocyte numbers are normal. Do you know of an organization? Selective IgM deficiency accompanied with IgG4 deficiency, dermal complications and a bronchial polyp. Selective IgA deficiency is seen in up to 6.17% of adult patients with SLE and 5.2% of pediatric patients with SLE. The incidence of SIgM deficiency in various races has not been reported, given the low overall incidence. They're your body's first line of defense against infections.
van Kuilenburg, in, Emery and Rimoin's Principles and Practice of Medical Genetics. ) IgG deficiency has been noted to occur in SLE patients and may be associated with infections. Clin Exp Nephrol. 2011 May.
The underlying cause of selective IgM deficiency (SIgMD) is not yet known. 57(1):99-105. Do you know of a review article? Ann Lab Med. 8:1056. 2017. [Medline]. [3] Yel L, Ramanuja S, Gupta S. Clinical and immunological features in IgM deficiency.
[1] Reported IgM concentrations in SIgM deficiency vary from 40 mg/dL (though some sources say 20 mg/dL) to undetectable levels (reference range 45-150 mg/dL in adults). Prophylactic antibiotics and prompt treatment of febrile illness are crucial. Clin Immunol Immunopathol. Common infections in these patients are bacterial (S. aureus, Pseudomonas aeruginosa, Streptococcus pneumoniae, Neisseria meningitides, Hemophilus influenza, Mycobaterium tuberculosis, Listeria monocytogenes, Brucella abortus), viral (Varicella zoster, Cytomegalovirus, Molluscum contagiosum), fungal (Pneumocystis carinii, Aspergillus fumigates), or protozoan (Giardia lamblia). Am J Med Genet. 19(1):118-30. Functional assessment of T and B lymphocytes in patients with selective IgM deficiency. 2002. These autoantibodies have been noted in 58% to 100% of SLE patients with selective IgA deficiency.

However, its significance remains unclear, because the clinical features, laboratory findings, disease activity, and course of patients with SLE and IgA deficiency are not different from those with normal IgA levels.71,72, Individuals with selective IgA deficiency frequently have circulating IgG antibodies to IgA.
[3, 4] In this context, remember that 2.1% of \"normal\" indi… Few PIDs have been described as consistently associated with SLE or lupus-like manifestations (Table 49.9): Homozygous deficiencies of early components of the classical complement pathway; Selective or partial immunoglobulin deficiencies, particularly isolated IgA and IgM deficiencies; and, CGD, in both patients and female carriers of the X-linked CGD allele (Table 49.2).13,14,21,38–41, Complete deficiency of any of the early components of the classical complement pathway represents the strongest single genetic risk factor for the development of SLE identified to date. 2013 May.

127A:99-100. We want to hear from you. Bronchopneumonia can be caused by adenovirus, enteritis can be caused by Cryptosporidium parvum, and arthritis and omphalophlebitis are common.210 Uveitis can occur as a result of R. equi. Although the molecular basis for selective immunoglobulin deficiencies is unknown, they are thought to relate to the differentiation of naïve B lymphocytes into immunoglobulin-secreting plasma cells. [Full Text]. Because this antibody helps provide protection against bacteria and viruses, having low IgM levels has been associated with a higher risk of recurring infections . Michael R Simon, MD, MA Clinical Professor Emeritus, Departments of Internal Medicine and Pediatrics, Wayne State University School of Medicine; Professor, Department of Internal Medicine, Oakland University William Beaumont University School of Medicine; Adjunct Staff, Division of Allergy and Immunology, Department of Internal Medicine, William Beaumont Hospital Rather, severe antibody deficiencies (e.g., agammaglobulinemia and CVID) are thought to be incompatible with the development of SLE lesions, since pathogenic autoantibodies seem necessary for tissue damage.26,43, In a large CGD series (368 patients), Winkelstein et al.38 found that 3.2% presented with discoid lupus erythematosus or SLE, and others reported this association not only in patients but also in female carriers of the X-linked CGD allele.21,39. 149(3):283-8. In Handbook of Vertebrate Immunology, 1998. There are no other underlying immunodeficiencies. Visit the group’s website or contact them to learn about the services they offer.
In contrast, a number of PIDs that are systematically or strongly associated with autoimmune manifestations are selectively “deprived” of SLE or lupus-like clinical or laboratory manifestations. [Medline].
IgG1 and IgG2 subclasses activate complement more efficiently than IgG3, and, in contrast, IgG4 is not complement fixing. Intern Med. Have a question? As well, the mortality after infection by vesicular stomatitis virus (VSV) was significantly reduced after transfer of normal serum. The cause of SIgM deficiency is unknown. [Medline].
Selective IgM deficiency was first described by Perryman et al.
