Abstract
AIMS/HYPOTHESIS Anorexia Nervosa (AN) is a severe psychiatric disorder of an unknown etiology with a crude mortality rate of about 5 % per decade, making it one of the deadliest of all psychiatric illnesses. AN is broadly classified into two main subtypes, restricting and binge/purging disorder. Despite extensive research efforts during several decades, the underlying pathophysiology of AN remains poorly understood. In this study, we aimed to identify novel protein biomarkers for AN by performing a proteomics analysis of fasting plasma samples from 78 females with AN (57 restrictive and 21 binge/purge type) and 70 healthy controls. METHODS Using state-of-the-art mass spectrometry-based proteomics technology in conjunction with an advanced bioinformatics pipeline, we quantify >500 plasma proteins. RESULTS Differential expression analysis and correlation of proteomics data with clinical variables led to identification of a panel of novel protein biomarkers with potential pathophysiological significance for AN. Our findings demonstrate evidence of a humoral immune system response, altered lipid metabolism and potential alteration of plasma cells in AN patients. Additionally, we stratified AN patients based on the quantified proteins and suggest a potential autoimmune nature in the restrictive subtype of AN. CONCLUSIONS/INTERPRETATION In summary, on top of biomarkers of AN subtypes, this study provides a comprehensive map of plasma proteins that constitute a resource for further studies of the pathophysiology of AN.

Abstract
Juvenile-onset systemic lupus erythematosus (jSLE) is an autoimmune disorder with multifaceted clinical findings in different organ systems. Neuropsychiatric manifestations affect more than half of SLE patients, and there is increasing evidence that anorexia nervosa (AN), a feeding and eating disorder (FED) characterized by significantly reduced energy intake, is among them. Herein, a review of the literature on the potential association between jSLE and AN was performed. Reported clinical cases were identified, and putative pathophysiological mechanisms were sought that could potentially explain the observed relationship between these two pathological entities. Four reports of isolated cases and a case series including seven patients were identified. In this limited patient pool, the diagnosis of AN preceded that of SLE in the majority of cases, whereas in all cases both entities were diagnosed within a time span of two years. Many explanations for the observed relationships have been proposed. AN has been associated with the stress of chronic disease diagnosis; on the other hand, the chronic inflammation associated with AN may contribute to the development/appearance of SLE. Adverse childhood experiences, concentrations of leptin, shared autoantibodies, and genetic traits appear to be important factors in this well-established interplay. In essence, it seems important to increase clinician awareness of the concomitant development of AN and SLE and invite further research on the subject.

Abstract
Immunological dysfunctions in eating disorders have recently gained increasing scientific attention. Furthermore, the reciprocal association between anorexia and autoimmune diseases is of particular interest and suggests a role of autoimmunity in the pathogenesis of eating disorders. Anorexia nervosa (AN) and autoimmune diseases are linked by a bidirectional relationship based on common immunopathological mechanisms. In this review, in addition to reporting the numerous cases described in which autoimmune disorders are associated with anorexia or vice versa, we summarize the many aspects of this relationship between the immune system (IS) and AN. We describe how the microbiota affects the IS, disrupts gut-brain communication, and possibly triggers eating disorders. We also describe the shared immunological pathways of autoimmune and eating disorders and in particular the occurrence of disrupted T cell tolerance and autoantibodies in AN. The described observations represent the starting point for possible, future research directions.

Abstract
Adolescence is a period in which eating disorders and juvenile systemic lupus erythematosus are typically diagnosed. The coexistence of both disorders prompts the search for a common aetiology. In this paper, we present a case of a 16-year-old girl with life-threatening anorexia nervosa followed by clinical and immunological manifestations of systemic lupus erythematosus. The severity of the symptoms of anorexia nervosa resulted in significant delay in proper diagnosis of the concomitant systemic disease which had already been active. The administration of immunosuppressive treatment resulted in decreased lupus activity and resolution of the symptoms of anorexia nervosa.Being affected by one severe and chronic disease does not preclude the coexistence of another disease of different aetiology. However, such coexistence may suggest a common pathophysiology. Many authors have indicated a possible link between anorexia nervosa and many autoimmune disorders. Currently, modern genetic techniques have confirmed a significant correlation between these disorders. This issue needs further investigation and may be helpful in arriving at the final diagnosis in similar cases.

Abstract
Anorexia nervosa (AN) is a severe eating disorder and often associated with altered humoral immune responses. However, distinct B cell maturation stages in peripheral blood in adolescents with AN have not been characterized. Treatment effects and the relationship between clinical and B cell parameters are also not fully understood. Here we investigated the phenotype of circulating B cell subsets and the relationship with body composition in adolescents with AN before (T0, n = 24) and after 6 weeks (T1, n = 20) of treatment. Using multi-parameter flow cytometry, we found increased percentages of antigen-experienced B cells and plasmablasts in patients with AN compared to healthy controls (n = 20). In contrast, percentages of CD1d+CD5+ B cells and transitional B cells with immunoregulatory roles were reduced at T0 and T1. These B cell frequencies correlated positively with fat mass, fat mass index (FMI), free fat mass index, and body mass index standard deviation score. In addition, scavenger-like receptor CD5 expression levels were downregulated on transitional B cells and correlated with fat mass and FMI in AN. Our findings that regulatory B cell subgroups were reduced in AN and their strong relationship with body composition parameters point toward an impact of immunoregulatory B cells in the pathogenesis of AN.

Abstract
This hypothesis is that anorexia nervosa (AN) is a biologically driven disorder, and mammalian hibernation may offer clues to its pathogenesis. Using this approach, this hypothesis offers suggestions for employing heart rate variability as an early diagnostic test for AN; employing the ketogenic diet for refeeding patients, attending to omega 3:6 ratio of polyunsaturated fatty acids (PUFAs) in the refeeding diet; and exploring clinical trials of the endocannabinoid-like agent, palmitoylethanolamde for patients with AN. This hypothesis also explores the role of lipids and autoimmune phenomena in AN, and suggest a lipodomics study to search for antibodies in the serum on patients with AN.

Abstract
A 13-year-old girl presented with significant weight loss, depression, anemia, and neutropenia. The preliminary diagnosis was anorexia nervosa combined with depression. Due to peripheral cytopenia, a bone marrow biopsy was performed to rule out leukemia. Lupus erythematosus (LE) cells were found in the bone marrow aspirate, which prompted autoantibody testing, although clinically it was not suspected the patient had systemic lupus erythematosus (SLE). Further testing demonstrated very high levels of antinuclear antibodies (ANA) (>12 U) and anti-double strand DNA (dsNDA) (>1000 IU/mL), which confirmed the diagnosis of SLE. The patient was treated with steroids for SLE, and symptoms improved quickly. In conclusion, although the identification of LE cells as one of the diagnostic criteria for SLE has been obsolete, careful examination of bone marrow to identify LE cells is still very important in the diagnosis of unsuspected SLE.

Abstract
OBJECTIVE Recent research indicates that eating disorders (ED) are associated with type 1 diabetes and Crohn's disease. The aim of this study was to determine whether, in a hospitalized population, a range of autoimmune diseases (AIDs) occurred more often than expected in people with anorexia nervosa (AN) or bulimia nervosa (BN), and whether AIDs elevated the risk of ED. METHOD Retrospective, record-linkage cohort study using national administrative statistical data on hospital care and mortality in England, 1999-2011. In people admitted when aged 10-44, cohorts of 8,700 females and 651 males with AN, and 4,783 females and 330 males with BN were constructed, along with a control cohort with the same age range. Results were expressed as risk ratios comparing each ED cohort with the control cohort. RESULTS The overall rate ratio for an AID after admission for AN was 2.04 (95% confidence interval 1.81-2.28) in females, and 1.14 (0.37-2.67) in males; and, for BN, 1.83 (1.56-2.14) in females, and 4.41 (2.11-8.10) in males. Rate ratios for AN after admission for an AID were 3.34 (2.94-3.79) in females, 3.76 (2.06-6.53) in males; and those for BN were 2.57 (2.22-2.97) in females, and 3.10 (1.50-5.90) in males. There were significant associations between ED and several specific individual AIDs. DISCUSSION Strong associations between ED and specific AIDs exist, although it is not possible from this study to determine if these are causal. Clinicians should be aware of the co-occurrence of these conditions. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:663-672).

Abstract
OBJECTIVE Sudden onset clinically significant eating restrictions are a defining feature of the clinical presentation of some of the cases of pediatric acute-onset neuropsychiatric syndrome (PANS). Restrictions in food intake are typically fueled by contamination fears; fears of choking, vomiting, or swallowing; and/or sensory issues, such as texture, taste, or olfactory concerns. However, body image distortions may also be present. We investigate the clinical presentation of PANS disordered eating and compare it with that of other eating disorders. METHODS We describe 29 patients who met diagnostic criteria for PANS. Most also exhibited evidence that the symptoms might be sequelae of infections with Group A streptococcal bacteria (the pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections [PANDAS] subgroup of PANS). RESULTS The clinical presentations are remarkable for a male predominance (2:1 M:F), young age of the affected children (mean=9 years; range 5-12 years), acuity of symptom onset, and comorbid neuropsychiatric symptoms. CONCLUSIONS The food refusal associated with PANS is compared with symptoms listed for the new Diagnostic and Statistical Manual of Mental Disorders, 5th ed. (DSM-V) diagnosis of avoidant/restrictive food intake disorder (ARFID). Treatment implications are discussed, as well as directions for further research.
