Bullying and Quality of Life in Pediatric Alopecia Areata
We report survey results that highlight the prevalence of bullying and surrounding emotional impact of AA in pediatric patients. We found that bullying was common overall and additional psychological impact, including impairment of social and home life, was even more common. Children of all ages experienced bullying. Boys reported increased physical bullying. Interestingly, those with more severe disease and longer duration of disease experienced less bullying than those with less severe disease.Skin Appendage Disord 2017;3:115-118 (Source: Skin Appendage Disorders)

Lupus Hepatitis and Autoimmune Hepatitis (Lupoid Hepatitis).
Abstract Liver dysfunction occurs in approximately 50% of patients with systemic lupus erythematosus (SLE), and patients with SLE and elevated liver enzymes can present a complicated and difficult differential diagnosis. Lupus hepatitis and autoimmune hepatitis are 2 immunologic conditions involving the liver, which can have similar clinical, laboratory and systemic presentations, leading to difficulties in diagnosis. Physicians need to be aware of these 2 hepatic diseases as diagnosis and appropriate therapy need to occur early in the disease course to prevent progression to advanced liver disease. We review the ...

A concise review of Hashimoto thyroiditis (HT) and the importance of iodine, selenium, vitamin D and gluten on the autoimmunity and dietary management of HT patients.Points that need more investigation.
Authors: Liontiris MI, Mazokopakis EE Abstract Hashimoto's thyroiditis (HT) is a chronic autoimmune thyroid disease caused by an interaction between genetic factors and environmental conditions, both of which are yet to be fully understood. The management of HT depends on its clinical manifestations, commonly including diffuse or nodular goiter with euthyroidism, subclinical hypothyroidism and permanent hypothyroidism. However, in most cases of patients with HT, lifelong levothyroxine substitution is required. The additional role of diet for the management of HT is usually overlooked.

Systemic Lupus Erythematosus Is Associated With Increased Adverse Postoperative Renal Outcomes and Mortality: A Historical Cohort Study Using Administrative Health Data.
CONCLUSIONS: This is, by far, the largest clinical study for postoperative outcomes of SLE patients with adequately powered statistical analyses. We concluded that SLE was associated with a higher risk of renal complications and in-hospital mortality but not cardiac events after major surgery. In SLE patients, more aggressive measures should be taken to prevent renal injury in the perioperative period. PMID: 28319545 [PubMed - in process] (Source: Anesthesia and Analgesia)

Overview of Celiac Disease in Russia: Regional Data and Estimated Prevalence.
Authors: Savvateeva LV, Erdes SI, Antishin AS, Zamyatnin AA Abstract Celiac disease (CD) is an autoimmune enteropathy triggered by the ingestion of dietary gluten from some cereals mainly in individuals carrying the HLA-DQ2 and/or HLA-DQ8 haplotypes. As an autoimmune disease, CD is manifested in the small intestine in the form of a progressive and reversible inflammatory lesion due to immune response to self-antigens. Indeed, CD is one of the most challenging medicosocial problems in current gastroenterology. At present, the global CD prevalence is estimated at approximately 1% based on data sent from different loc...

Seroprevalence survey of selective anti-neuronal autoantibodies in patients with first-episode schizophrenia and chronic schizophrenia
Autoimmune encephalopathy caused by autoantibodies against neuronal cell-surface proteins in the brain is a newly discovered disease category associated with psychiatric disorders. Correct diagnosis of this condition relies on the detection of specific autoantibodies in the blood or cerebral spinal fluid in addition to the clinical presentations. The study aimed to understand the seroprevalence of selective anti-neuronal autoantibodies in our patients with schizophrenia. First, we screened for six anti-neuronal autoantibodies in an archived blood sample collected from patients with the first-episode schizophrenia. (Source:...

Are the autoimmune/inflammatory syndrome induced by adjuvants (ASIA) and the undifferentiated connective tissue disease (UCTD) related to each other? A case-control study of environmental exposures
AbstractThe autoimmune/inflammatory syndrome induced by adjuvants (ASIA) is an entity that includes different autoimmune conditions observed after exposure to an adjuvant. Patients with undifferentiated connective tissue disease (UCTD) present many signs and symptoms of ASIA, alluding to the idea that an exposure to adjuvants can be a trigger also for UCTD. The aim of this case-control study was to investigate exposure to adjuvants prior to disease onset in patients affected by UCTD. Ninety-two UCTD patients and 92 age- and sex-matched controls with no malignancy, chronic infections, autoimmune disease nor family history o...

Gender differences are observed in the activity of multiple immunological pathways, even in healthy individuals. Many autoimmune diseases, both systemic and organ-specific, are characterized by a greater prevalence in females than males. Liang and colleagues identified a female-biased molecular signature, involving immunological factors, in association with autoimmune disease susceptibility, and this signature was independent of age or sex hormone regulation but was regulated by the putative transcription factor VGLL3, which had strong female-biased expression.

The blood in systemic disease
Systemic disease has protean manifestations. Most frequently observed is anaemia of chronic disease, anaemia can also be autoimmune, microangiopathic, mechanical or caused by haematinic deficiency, bone marrow replacement or pure red cell aplasia. The platelet count can be increased or decreased. The number of neutrophils, eosinophils, monocytes and lymphocytes can be increased, but neutropenia, eosinopenia and lymphopenia can also occur. Leucocytes can appear activated. Systemic disease can lead to thromboembolism, haemorrhage or disseminated intravascular coagulation. (Source: Medicine)

Predicting the effects of potentially therapeutic modified peptides on polyclonal T cell populations in a mouse model of multiple sclerosis
Altered peptide ligands (APLs) have routinely been studied in clonal populations of Th cells that express a single T cell receptor (TCR), but results generated in this manner poorly predict the effects of APLs on polyclonal Th cells in vivo, contributing to the failure of phase II clinical trials of APLs in autoimmune diseases such as multiple sclerosis (MS). We have used a panel of APLs derived from an encephalitogenic epitope of myelin proteolipid protein to investigate the relationship between antigen cross-reactivity in a polyclonal environment, encephalitogenicity, and the capacity of an APL to provide protection agai...

Two decades of glatiramer acetate: From initial discovery to the current development of generics
Multiple sclerosis (MS) is a chronic, incurable, inflammatory disease of the central nervous system. In the United States, several Food and Drug Administration (FDA)-approved disease-modifying treatments (DMTs) are available, including glatiramer acetate (GA; Copaxone ®), one of the most longstanding treatments. GA was discovered serendipitously in the late 1960s/early 1970s while attempting to produce a synthetic antigen capable of inducing experimental autoimmune encephalomyelitis (EAE), an animal model of autoimmune inflammatory CNS disorders, including MS.

The universe of ANA testing: a case for point-of-care ANA testing
AbstractTesting for total antinuclear antibodies (ANA) is a critical tool for diagnosis and management of autoimmune diseases at both the primary care and subspecialty settings. Repurposing of ANA from a test for lupus to a test for any autoimmune condition has driven the increase in ANA requests. Changes in ANA referral patterns include early or subclinical autoimmune disease detection in patients with low pre-test probability and use of negative ANA results to rule out underlying autoimmune disease. A positive result can lead to further diagnostic considerations. Currently, ANA tests are performed in centralized laborato...

An Activating Mutation in STAT3 Results in Neonatal Diabetes Through Reduced Insulin Synthesis
Neonatal diabetes mellitus (NDM) is a rare form of diabetes diagnosed within the first 6 months of life. Genetic studies have allowed the identification of several genes linked to the development of NDM; however, genetic causes for ~20% of the cases remain to be clarified. Most cases of NDM involve isolated diabetes, but sometimes NDM appears in association with other pathological conditions, including autoimmune diseases. Recent reports have linked activating mutations in STAT3 with early-onset autoimmune disorders that include diabetes of autoimmune origin, but the functional impact of STAT3-activating mutations have not...

Identification of Unique Antigenic Determinants in the Amino Terminus of IA-2 (ICA512) in Childhood and Adult Autoimmune Diabetes: New Biomarker Development
CONCLUSIONS We developed a new antibody biomarker identifying novel antigenic determinants within the N terminus of IA-2. IA-2ec autoantibodies can be detected in patients with type 1 diabetes and in a subgroup of adult autoimmune patients with type 2 diabetes phenotype negative for conventional islet autoantibody testing. These observations suggest that islet autoimmunity may be more common in clinically diagnosed type 2 diabetes than previously observed. (Source: Diabetes Care)

Low ‐dose interleukin‐2 promotes STAT‐5 phosphorylation, Treg survival and CTLA‐4‐dependent function in autoimmune liver diseases
We reported recently that the hepatic microenvironment is deficient in interleukin (IL)−2, a cytokine essential for Treg survival and function. Consequently, few liver‐infiltrating Treg demonstrate signal transducer and activator of transcription‐5 (STAT‐5) phosphorylation. To establish the potential of IL‐2 to enhance Treg therapy, we investigated the effects of very low dose Proleukin (VLDP) on the phosphorylation of STAT‐5 and the subsequent survival and function of Treg and T effector cells from the blood and livers of patients with autoimmune liver diseases. VLDP, at less than 5 IU/ml, resulted in selectiv...

miRNAs: novel regulators of autoimmunity-mediated pancreatic β-cell destruction in type 1 diabetes.
Abstract MicroRNAs (miRNAs) are a series of conserved, short, non-coding RNAs that modulate gene expression in a posttranscriptional manner. miRNAs are involved in almost every physiological and pathological process. Type 1 diabetes (T1D) is an autoimmune disease that is the result of selective destruction of pancreatic β-cells driven by the immune system. miRNAs are also important participants in T1D pathogenesis. Herein, we review the most recent data on the potential involvement of miRNAs in T1D. Specifically, we focus on two aspects: the roles of miRNAs in maintaining immune homeostasis and regulating β-cell...

Genetics of Vitiligo
Vitiligo reflects simultaneous contributions of multiple genetic risk factors and environmental triggers. Genomewide association studies have discovered approximately 50 genetic loci contributing to vitiligo risk. At many vitiligo susceptibility loci, the relevant genes and DNA sequence variants are identified. Many encode proteins involved in immune regulation, several play roles in cellular apoptosis, and others regulate functions of melanocytes. Although many of the specific biologic mechanisms need elucidation, it is clear that vitiligo is an autoimmune disease involving a complex relationship between immune system pro...

Special Considerations in Children with Vitiligo
Childhood vitiligo differs from adult-onset vitiligo for several features including increased incidence of the segmental variant, higher prevalence of halo nevi, and more common family history for autoimmune diseases and atopic diathesis. The major differential diagnoses are the postinflammatory hypomelanoses for nonsegmental vitiligo and nevus depigmentosus for segmental vitiligo. From a therapeutic standpoint, early awareness of the diagnosis seems to correlate with a good treatment outcome in this age group. (Source: Dermatologic Clinics)

Segmental vitiligo is characterized by its early onset, rapid stabilization, and unilateral distribution. Recent evidence suggests that segmental and nonsegmental vitiligo could represent variants of the same disease spectrum. Observational studies with respect to its distribution pattern point to a possible role of cutaneous mosaicism, whereas the original stated dermatomal distribution seems to be a misnomer. Although the exact pathogenic mechanism behind the melanocyte destruction is still unknown, increasing evidence has been published on the autoimmune/inflammatory theory of segmental vitiligo.

Acute zonal occult outer retinopathy affecting the peripheral retina with centripetal progression
Conclusion: A variant of AZOOR may involve the peripheral retina, causing concentric zonal atrophy with centripetal progression, with central peripapillary zonal abnormalities that have centrifugal progression. This may eventually lead to widespread atrophic degeneration with severe visual field loss. Wide-field imaging of the peripheral retina and monitoring of the visual fields are important to document this rare atypical presentation of AZOOR and any subsequent disease progression.
