INTRODUCTION: Immunotherapy has been approved for treatment of melanoma. Autoimmune endocrinopathies have been reported in trials involving immunotherapy but autoimmune diabetes has not been definitively linked to them. Here we describe a case of autoimmune diabetes presenting with DKA after receiving combined immunotherapy with anti-CTLA4 and anti-PD1 monoclonal antibodies. CASE: A 47year old gentleman with metastatic melanoma presented to our institution with confusion, abdominal pain and decreased oral intake...

Aims. Latent autoimmune diabetes in adults (LADA) is an autoimmune disease of which the mechanism is not clear. Emerging evidence suggests that histone methylation contributes to autoimmunity. Methods. Blood CD4(+) T lymphocytes from 26 LADA patients and 26 healthy controls were isolated to detect histone H3 lysine 4 and H3 lysine 9 methylation status. Results. Reduced global H3 lysine 9 methylation was observed in LADA patients' CD4(+) T lymphocytes, compared to healthy controls (P < 0.05). H3 lysine 4 methylation was not statistically different...

Cytomegalovirus (CMV) is a latent virus which causes chronic activation of the immune system. Here, we demonstrate that cytotoxic and pro-inflammatory CD4(+)CD28(null) T cells are only present in CMV seropositive donors and that CMV-specific Immunoglobulin (Ig) G titers correlate with the percentage of these cells. In vitro stimulation of peripheral blood mononuclear cells with CMVpp65 peptide resulted in the expansion of pre-existing CD4(+)CD28(null) T cells. In vivo, we observed de novo formation, as well as expansion of CD4(+)CD28(null) T cells in two different chronic inflammation models, namely the murine CMV (MCMV) model and the experimental autoimmune encephalomyelitis (EAE) model for multiple sclerosis (MS)...

Graves' disease is an autoimmune disease that results in and is the most common cause of hyperthyroidism, and the reactivation of persisting Epstein-Barr virus (EBV) in B lymphocytes induces the differentiation of host B cells into plasma cells. We previously reported that some EBV-infected B cells had thyrotropin receptor antibodies (TRAbs) as surface immunoglobulins (Igs), and EBV reactivation induced these TRAb+EBV+ cells to produce TRAbs. EBV reactivation induces Ig production from host B cells. The purpose of the present study was to examine total Ig productions from B cell culture fluids and to detect activation-induced cytidine deaminase (AID), nuclear factor kappa B (NF-κB), and EBV latent membrane protein (LMP) 1 in culture B cells during EBV reactivation induction and then we discussed the mechanisms of EBV reactivation-induced Ig production in relation to autoimmunity...

Bariatric surgery is an effective treatment of type 2 diabetes in obese patients. The obesity epidemic does not spare patients with type 1 diabetes mellitus (T1DM), but there is no consensus regarding the role of surgery in the management of obese T1DM patients. Published data consistently report significant weight loss after surgery in obese T1DM patients, but long-term glycaemic control remains difficult to achieve. Here we present our experience with a challenging patient and a review of the literature. Our patient successfully underwent a roux-en-Y gastric bypass (RYGB) when she was 28 years old...

Rheumatoid arthritis (RA) is a relatively common autoimmune disease that is associated with progressive disability and systemic complications, with a relatively high socioeconomic burden. The treatment of RA has been revolutionized by the use of biological drugs, such as anti-tumor necrosis factor (TNF) agents. A wide spectrum of RA disease severity has been reported among patients with human immunodeficiency virus (HIV) infection. Yet, only a few cases using anti-TNF therapy have been described in this clinical population...

Interstitial pneumonia with autoimmune features (IPAF) is a term to describe individuals with both interstitial lung disease (ILD) and combinations of other clinical, serologic, and/or pulmonary morphologic features, which presumably originate from an underlying systemic autoimmune condition, but do not meet current rheumatologic criteria for a defined connective tissue disease (CTD). Predominantly, interstitial pneumonia arises in the course of an established CTD, but it is not so rare for the ILD to be the first, and possibly the one and only manifestation of a latent CTD...

Diabetes mellitus is a chronic disorder caused by relative or absolute insulin deficiency and characterized by chronic hyperglycaemia. It is expected that by year 2025, 80% of all type 2 diabetic patients will be living in developing or low- and middle-income countries. Among Asians, there has been an overall increase in abdominal obesity; however, the risk of diabetes in these populations starts at much lower body mass index as compared to Caucasians. A significant proportion of diabetic patients with adult-onset, initially nonrequiring insulin treatment, have diabetes-associated autoantibodies in their sera...

Most therapeutic attempts to prevent the progression of kidney diseases have been based on interventions to inhibit the production of transforming growth factor-β (TGF-β). Thrombospondins (TSPs) play an important role in activating TGF-β. In the healthy kidney, two TSPs are expressed, TSP1 and TSP2, which exert contrasting effects. While TSP1 is a major activator of TGF-β in renal cells and exerts pro-inflammatory effects both in vitro and in vivo, TSP2 lacks the ability for TGF-β activation but regulates matrix remodeling and inflammation in experimental kidney disease...

OBJECTIVES: Autoantibodies are useful biomarkers for diagnosing and monitoring treatment in some autoimmune diseases. Antibodies against isoforms of 14-3-3 protein have been proposed as biomarkers for the presence of aortic aneurysm in large-vessel vasculitis (LVV). Here, we aimed to evaluate the diagnostic role and potential immunopathological involvement of anti-14-3-3 antibodies in newly diagnosed LVV patients. METHODS: Antibodies against three isoforms of 14-3-3 (γ, ε and ζ) were measured in 90 subjects: 48 GCA and 3 Takayasu's arteritis (TA) patients, and 39 controls (non-inflammatory and inflammatory diseases), using a multiplexed bead-based immunoassay and immunoprecipitation studies...

Tuberculosis (TB) is a disease caused by Mycobacterium tuberculosis. Despite the availability of novel therapeutic approaches, TB is considered as one of the leading causes of death due to infectious diseases worldwide. Alveolar macrophages are the first line of defense against M. tuberculosis; they ingest and sequester the bacilli within granulomatous structures. Control and resolution of the infection requires activated T lymphocytes as well as Th1 cytokines. There are two forms of TB: active TB and latent TB...

Oral administration of Ag induces regulatory T cells that express latent membrane-bound TGF-β (latency-associated peptide [LAP]) and have been shown to play an important role in the induction of oral tolerance. We developed an in vitro model to study modulation of LAP(+) on CD4(+) T cells. The combination of anti-CD3 mAb, anti-CD28 mAb, and recombinant IL-2 induced expression of LAP on naive CD4(+) T cells, independent of Foxp3 or exogenous TGF-β. In vitro generated CD4(+)LAP(+)Foxp3(-) T cells were suppressive in vitro, inhibiting proliferation of naive CD4(+) T cells and IL-17A secretion by Th17 cells...
