In any other lupus patient, the activity may be reduced but is usually not very low or nearly absent. Other PIDs that may present with SLE or SLE-like presentation include prolidase deficiency, AicardiCGoutires syndrome (type 1 interferonopathies), protein kinase C (PRKC) delta deficiency, and carrier females of X-linked chronic granulomatous disease.[1] Cutaneous manifestations of other common main immunodeficiency disorders Common variable immunodeficiency CVID is the most common clinically significant PID with a variable clinical phenotype. contagiosum (in autosomal recessive hyper IgE syndrome); chronic mucocutaneous candidiasis (in hyper IgE syndrome, autoimmune polyendocrinopathy candidiasis ectodermal dysplasia syndrome, Th17 cell defects); recurrent nonhealing ulcers (in leucocyte adhesion defect); skin abscesses (in antibody defects, hyper IgE syndrome, and chronic granulomatous disease); petechial or purpuric spots (in WiskottCAldrich syndrome). is the most common offending pathogen followed by spp. Eczema usually exacerbates with contamination and tends to subside with its treatment. Skeletal abnormalities are more apparent in older children and may include high arched palate, craniosynostosis, kyphosis, scoliosis, minimal trauma fractures of long bones, and joint hyperextensibility. In adolescents, retained primary tooth is another characteristic obtaining. The vascular abnormalities that these patients may develop are aneurysm of intracranial arteries leading to stroke or lacunar infarcts in the brain and myocardial infarction due to coronary artery abnormalities (aneurysms and tortuosity). ML604086 These patients are also at high risk for development of lymphoma. Serum IgG, IgA, and IgM; T and B lymphocytes, and natural killer (NK) cells are usually normal. The National Institutes of Health (NIH) scoring system is a clinically useful tool for evaluation of patients with suspected AD-HIE syndrome.[15] NIH score of 40 has been found to correlate with presence of a molecular defect in gene. Autosomal recessive hyper IgE syndrome AR-HIES due to mutation in gene is usually characterized by recurrent viral skin infections, atopic dermatitis, asthma, food allergies, and anaphylaxis.[16,17] Though not consistent, these patients may have recurrent staphylococcal abscess, recurrent respiratory infections, strokes, and vascular aneurysms. However, unlike AD-HIES, pneumatoceles, coarse facies, dysmorphism, skeletal abnormalities, and retained primary tooth are not seen. mutation has recently been explained in patients with predominant mycobacterial and viral infections without HIES [Table 3].[18] Patients with phosphoglucomutase 3 (mutation may also ML604086 have neutropenia, lymphopenia, low serum IgM, and variable IgG antibody responses.[19] In addition, they may also have abnormal electroencephalographic (EEG) changes and hypomyelination on brain magnetic resonance imaging (MRI).[20] DOCK8 deficiency This AR form of HIES (caused by a mutation in the gene) has now been grouped under combined immunodeficiency diseases.[1] There are numerous overlapping features with AD-HIES such as eczema; staphylococcal and candida infections; elevated serum IgE and eosinophilia. However, patients with deficiency are more predisposed to severe viral infections such as considerable molluscum contagiosum contamination and herpes contamination; these patients usually have allergies, have neurological symptoms (vasculitis, meningitis, and brain infarction); do not develop somatic abnormalities such as coarse facies, delayed fall of deciduous teeth; newborn rash is usually less common and pneumatoceles are rarely seen.[21,22,23] These patients are more prone for malignancy (squamous cell carcinoma, cutaneous T-cell lymphoma and EBV related lymphomas). Th17 cells are often normal but CD4+ T cells and CD8+ T cells are often reduced. Elevated IgE and eosinophilia is present in ML604086 almost all cases. IgA and IgG is usually normal or high but IgM tends to be low.[21] IPEX This is an X-linked disorder due to mutation in the forkhead-winged helix transcription factor (is usually involved in the TFRC development and function of CD4+ CD25+ regulatory T cells (Treg) that control effector T cells. Absence of Treg cells in IPEX prospects to numerous autoimmune manifestations [Table 3].[24] IPEX usually manifests in neonatal period with large watery diarrhea (autoimmune enteropathy), which may sometime be mucoid or bloody and prospects to failure to thrive. Skin disease may manifest in the neonatal period. Most common presentation is usually eczematoid dermatitis and other less common manifestations include icthysiform or psoriasiform dermatitis, urticaria, and ML604086 alopecia. Autoimmune manifestations are common and include type I diabetes mellitus occurring in early infancy, hyperthyroidism or hypothyroidism, AIHA, thrombocytopenia, neutropenia, arthritis, hepatitis, and nephritis. Patients with IPEX do not have impaired response to pathogens; however, breach of physical barrier of.
