Latent autoimmune diabetes in adults (LADA) usually refers to GADAb positive diabetes with onset after 35 years of age and no insulin treatment within the first 6 months after diagnosis. However, it is not always easy to distinguish LADA from type 1 or type 2 diabetes.In this study we examined whether metabolite profiling could help to distinguish LADA (N=50) from type 1 (N=50) and type 2 diabetes (N=50).Out of 123 identified metabolites, 99 differed between the diabetes types. However, no unique metabolite profile could be identified for any of the types...

Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease characterized by multiorgan inflammation induced by autoantibodies. Early growth response gene 2 (Egr2), a transcription factor essential for T-cell anergy induction, controls systemic autoimmunity in mice and humans. We have previously identified a subpopulation of CD4(+) regulatory T cells, CD4(+)CD25(-)LAG3(+) cells, that characteristically express both Egr2 and LAG3 and control mice model of lupus via TGF-β3 production. However, due to the mild phenotype of lymphocyte-specific Egr2-deficient mice, the presence of an additional regulator has been speculated...

Eliza F Chakravarty
Herpes zoster is the reactivation of latent varicella zoster virus usually occurring decades after initial exposure, and manifesting as a painful vesicular rash occurring along one or more dermatomes. Zoster incidence increases with age as cell mediated immunity against latent virus wanes. Epidemiological evidence suggests that individuals with underlying rheumatic diseases are at increased risk for zoster. It remains unclear whether this is due to immunosuppressive medications or from immune dysregulation of the underlying disease...

INTRODUCTION: Latent autoimmune diabetes in adult (LADA) is a form of Type 1 diabetes mellitus (T1DM) that occurs in adult or with advancing age. It commonly occurs in people aged ≥30 years and is characterized by initial response to oral hypoglycemic agents, lean body mass, and presence of glutamic acid decarboxylase autoantibody (GAD-Ab). It exhibits rapid deterioration of the pancreatic β-cells secretory function due to the destructive action of the autoantibodies. The prevalence of LADA among T2DM patients varies among population due to different diagnostic criteria, patients' characteristics, the assay used, and genetic predisposition...

Excessive transforming growth factor (TGF)-β is associated with pro-fibrotic responses in lung disease, yet it also plays essential roles in tissue homeostasis and autoimmunity. Therefore, selective inhibition of excessive and aberrant integrin-mediated TGF-β activation via targeting the alpha-v family of integrins is being pursued as a therapeutic strategy for chronic lung diseases, to mitigate any potential safety concerns with global TGF-β inhibition. In this work, we reveal a novel mechanism of inhibiting TGF-β activation utilized by an αvβ8 targeting antibody, 37E1B5...

A 36-year-old woman developed hypokalemic metabolic alkalosis after anti SS-A antibody was found to be positive. Diuretic loading test results were compatible with Gitelman syndrome (GS). The patient had a heterozygous mutation in SLC12A3, which encodes for thiazide-sensitive NaCl cotransporter (NCCT). While the mutation may be responsible for a latent hypofunction of NCCTs, the underlying anti-SSA antibody-associated autoimmunity induced the manifestation of its hypofunction. To the best of our knowledge, this is the first report to demonstrate that anti SS-A antibody-associated autoimmunity may induce GS in a patient with a SLC12A3 heterozygous mutation...

Inflammation-induced heat shock proteins (HSPs) and hypovitaminosis D have been reported to impact immune responses and to be associated with autoimmune diseases including celiac disease (CD), a gluten-sensitive enteropathy mediated by autoantibodies against tissue transglutaminase (TG2). Recently, we provided evidence for a role of autoantibodies to HSPs in patients with dermatitis herpetiformis (DH), an inflammatory skin disease induced by underlying latent CD. In this study, we aimed at investigating the humoral autoimmune response to HSPs and vitamin D status in CD patients (n=15) presenting without the cutaneous disease manifestation...

Rituximab is a monoclonal antibody that depletes B cells from the circulation. It was originally used to treat lymphoma but is increasingly used for the treatment of autoimmune diseases. Rituximab was found to be effective in randomised controlled trials for rheumatoid arthritis, granulomatosis with polyangiitis and other antineutrophil cytoplasmic antibody-associated vasculitides. However, evidence of efficacy is very limited for many other autoimmune conditions. Before starting rituximab, it is important to check the patient's baseline immunoglobulins and immunisation status...

BACKGROUND: It is not always easy to classify diabetes (DM) diagnosed in adults, with a significant group of patients initially classified and treated for type 2 diabetes mellitus (DM2T) presenting signs indicating the presence of autoimmune insulitis (AI), which is characteristic of type 1 diabetes mellitus (DM1T), or latent autoimmune diabetes mellitus in adults (LADA). GOAL: Identify the proportion of patients entered with DM2T who present AI signs, and the number of patients of that proportion, who at the same time present low insulin secretion, and what clinical and laboratory manifestations could be used to differentiate between these patients...

RATIONALE: Patients exposed to second-generation antipsychotics (SGAs) have approximately 10 times increased risk of diabetic ketoacidosis (DKA) compared with the general population. However, as DKA is a rare complication of type 2 diabetes mellitus, and susceptible patients exposed to antipsychotics may rapidly develop DKA independently of treatment duration and weight gain, this is rather suggestive of type 1 diabetes mellitus (T1DM) or latent autoimmune diabetes in adults. OBJECTIVES: We performed a systematic review of current studies regarding antipsychotic-associated DKA with type 1 etiology and analyzed Danish adverse drug event (ADE) reports (previously unpublished cases)...

OBJECTIVE: We related organ-specific autoantibodies, including diabetes-associated autoantibodies (DAAs) and non-DAAs to systemic cytokines/chemokines in type 1 and type 2 diabetes. RESEARCH DESIGN AND METHODS: From the European Action LADA (latent autoimmune diabetes in adults) cohort, patients with adult-onset type 1 diabetes (n = 80, of whom 50 had LADA and 30 had classic type 1 diabetes) and type 2 diabetes (n = 626) were analyzed for DAAs (GAD antibody [GADA], IA-2 antigen, islet cell antibody, and zinc transporter T8), non-DAAs (transglutaminase, thyroid peroxide autoantibodies, parietal cell antibodies), and 10 immune mediator concentrations (measured by LUMINEX)...

The clinical presentation of diabetes sometimes overlaps, contributing to ambiguity in the diagnosis. Thus, circulating pancreatic islet-enriched microRNAs (miRNAs) might be useful biomarkers of β-cell injury/dysfunction that would allow more accurate subtyping of diabetes. We measured plasma levels of selected miRNAs in subjects with prediabetes (n = 12), type 2 diabetes (T2D, n = 31), latent autoimmune diabetes of adults (LADA, n = 6) and type 1 diabetes (T1D, n = 16) and compared them to levels in healthy control subjects (n = 27)...

BACKGROUND: Regulatory T cells (Treg) are an essential arm of adaptive immunity not only in tolerance and autoimmunity but also in infectious diseases. In Tuberculosis (TB), it has been suggested that the frequency of Tregs is higher in the blood of TB patients when compared to healthy controls with subsequent decline after treatment. However, with the discovery that FOXP3, the hallmark marker of Tregs, is not exclusive to Tregs and the lack of specific markers for Tregs, it has been a challenge to fully understand the role of Tregs in TB...

Development of treatment with immunomodulatory agents has improved prognosis of various autoimmune-related diseases. A sphingosin-1-phosphate receptor modulator, or fingolimod, is the first licensed oral drug for relapsing-remitting multiple sclerosis. The agent reduces circulating lymphocytes by trapping T cells in lymph nodes, possibly leading to reactivation of latent viruses. A 41-year-old Japanese woman who had been treated with fingolimod for 2 years presented with unilateral sore throat. Laryngoscopy revealed exudates unilaterally emerging on the left side of her supraglottic region...
