BACKGROUND: Posttransplantation diabetes mellitus (PTDM) has been associated with inferior patient and allograft outcomes. However, previous studies didn't identify differences in infection control and alloreactivity. METHODS: We studied 449 kidney transplant recipients (KTRs) between 2005 and 2013. 50 (11.1%) KTRs were diagnosed with PTDM and 60 (13.4%) KTRs with pre-existing diabetes. Samples were collected pretransplantation, at +1, +2, +3 months posttransplantation...

We report a 27-year-old pregnant woman with polyuria, polydipsia and headache in the third trimester of pregnancy. Hypernatremia (153 mEq/L), high plasma osmolality (300 mOsm/kgH2O) and low urinary osmolality (92 mOsm/kgH2O) were observed at the admission to our hospital. Plasma arginine vasopressin (AVP) level was inappropriately low (2.2 pg/mL) compared to the high plasma osmolality. Plasma AVP responses to hypertonic-saline infusion were blunted, and her urine osmolality increased in response to desmopressin...

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...

Metformin (MET), the first-line medication for Type-2 Diabetes (T2D), has been shown to reduce chronic inflammation indirectly through reduction of hyperglycemia, or directly acting as anti-inflammatory drug. The effects of MET on B lymphocytes is uncharacterized. In the present study, we measured in vivo and in vitro influenza vaccine responses in 2 groups of T2D patients: recently diagnosed but not taking anti-diabetic drugs, and patients taking MET. Results show that B cell function and vaccine responses, hampered by obesity and T2D, are recovered by MET...

BACKGROUND: Cytotoxic T lymphocyte antigen-4 (CTLA-4) plays a pivotal role in immune homeostasis. Dysregulated expression of CTLA-4 leads to many autoimmune diseases, including rheumatoid arthritis, systemic lupus erythematosus, and type 1 diabetes (T1D). There has been a controversial association between the CTLA-4 +49 G/A SNP (rs231775) and autoimmune diseases. Therefore, this meta-analysis was performed to assess the link between rs231775 and autoimmune disease risk. MATERIALS AND METHODS: We retrieved the available studies from PUBMED and EMBASE through February, 2016 and then performed meta-analyses that included all populations, as well as by ethnicity...

Background: Metabolic syndrome (MetS) is a risk factor for development of cancer. Because aberrant lipid metabolism is a pathogenic feature of chronic lymphocytic leukemia (CLL), our objective was to determine if CLL patients have a higher prevalence of MetS preceding diagnosis and to determine the impact of lipid-lowering medications on survival. Methods: We conducted a population-based case-control study in Ontario, Canada, using administrative databases of adults age 66 years and older to compare the prevalence of MetS preceding CLL with age- and sex-matched control subjects...

Despite the benefit of insulin, blockade of autoimmune attack and regeneration of pancreatic islets are ultimate goals for the complete cure of type 1 diabetes (T1D). Long-term consumption of ω-3 polyunsaturated fatty acids (PUFAs) is known to suppress inflammatory processes, making these fatty acids candidates for the prevention and amelioration of autoimmune diseases. Here, we explored the preventative and therapeutic effects of ω-3 PUFAs on T1D. In NOD mice, dietary intervention with ω-3 PUFAs sharply reduced the incidence of T1D, modulated the differentiation of Th cells and Tregs, and decreased the levels of IFN-γ, IL-17, IL-6, and TNF-α...

Lymphocytes are the key effector cells of the adaptive immune response but are also implicated in the development of chronic inflammatory diseases such as type 2 diabetes, cardiovascular disease, inflammatory bowel disease, and allergy. In order to understand the mechanisms responsible for the global increase in such debilitating conditions it is vital to appreciate the complexity of immune cell trafficking into tissue under normal and inflamed conditions. In this chapter we introduce the mechanisms of immune cell recruitment into tissue and highlight how these processes have been targeted by new therapeutic entities based on blocking integrin or chemokine function...

INTRODUCTION: Progressive multifocal leukoencephalopathy (PML) is a rare demyelinating brain infection caused by JC polyomavirus (JCV), primarily seen in patients with severely compromised cellular immunity. Clinical presentation varies depending on the affected white matter. PML prognosis is variable and effective treatments are lacking. CASE PRESENTATION: A 75-year-old Chinese woman with type 2 diabetes mellitus, chronic kidney disease and rheumatoid arthritis, treated with low-dose methotrexate and prednisolone for 2...

Rap1-interacting adaptor molecule (RIAM) is a Rap1 effector that mediates the recruitment of talin to integrins, thereby supporting their activation. In this study, we investigated the role of RIAM in an adoptive transfer model for type I diabetes and report that RIAM expression in T cells is necessary for diabetes development. Loss of RIAM did not prevent lymphocyte recruitment to draining lymph nodes 24 h after transfer, but it was required for Ag-driven proliferation and cytotoxic killing. RIAM is recruited to immune synapses along with talin and LFA-1, and loss of RIAM profoundly suppresses Ag-dependent conjugate formation in primary naive and effector T cells...

We read with great interest the article by Pascual et al., in which subclinical atherosclerosis in patients with hidradenitis suppurativa (HS) was assessed using carotid ultrasound. They found a higher prevalence of subclinical atherosclerosis in HS patients (30.7%) compared with controls (16.1%) and the association was significant in patients 40 years and older. Furthermore, traditional cardiovascular (CV) risk factors like hypertension (41.9%), diabetes mellitus (22.6%), and metabolic syndrome (38.7%) along with elevated systemic inflammatory markers including high-sensitivity C-reactive protein (Hs-CRP) (61...

BACKGROUND: Atazanavir (ATV) not boosted by ritonavir (uATV) has been frequently used in the past for switching combination antiretroviral therapy (cART). However, the clinical outcomes and predictors of such strategy are unknown. METHODS: An observational study was carried out on the Italian MASTER, selecting HIV infected patients on cART switching to an uATV-containing regimen. Baseline was set as the last visit before uATV initiation. In the primary analysis, a composite clinical end-point was defined as the first occurring of any condition among: liver, cardiovascular, kidney, diabetes, non AIDS related cancer or death events...
