IgG4-related disease (IgG4-RD) is a rare fibro-inflammatory condition that can affect almost any organ, characterized by tumefactive lesions and often by eosinophilia and elevated serum IgG4 concentrations. The aim of the study is to analyze in IgG4-RD patients the serum levels of a group of cytokines and growth factors potentially involved in the regulation of fibrotic processes. In the sera of 12 patients affected by IgG4-RD and of 15 normal healthy subjects (NHS), pro-fibrogenic mediators (TGF-β1 and periostin) and pro- (VEGF and angiogenin-1) and anti- (endostatin and thrombospondin-1) angiogenic mediators were measured by sandwich enzyme immunoassay...

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease of undefined etiology and with remarkably heterogeneous clinical features. Virtually any organ system can be affected, including the eye. SLE-related eye involvement can be diagnosed in approximately one-third of the patients and is usually indicative of disease activity. An early diagnosis and the adoption of suitable therapeutic measures are necessary to prevent sight-threatening consequences, especially in patients with juvenile SLE. Periocular lesions, such as eyelid involvement and orbital inflammation, are relatively rare and, in case of orbital masses, may require a biopsy control...

Apoptosis is essential for maintaining tissue homoeostasis in multi-cellular organisms, also occurring as a defence mechanism against a number of infectious agents, such as parasites. Among intracellular protozoan parasites reported to interfere with the apoptotic machinery of the host cell, Leishmania (L.) sp. have been described, although the various species might activate different pathways in their host cells. Since until now it is not yet well clarified the signalling pathway involved in the apoptosis modulation by L...

Xanthine oxidase (XO) is an important enzyme responsible for conversion of purine bases to uric acid and represents the major source of reactive oxygen species (ROS) production in circulation. Since pathophysiological mechanism of the relationship between XO activity and urinary albumin excretion (UAE) rate is not well elucidated, we aimed to investigate this association in patients with diabetes mellitus type 2 (DM2). In addition, we wanted to examine whether uric acid itself plays an independent role in albuminuria onset and progression, or it is only mediated through XO activity...

T helper (Th) 17 cells have a critical role in the pathogenesis of chronic hepatitis B virus (HBV) infection, and basic leucine zipper transcription factor, ATF-like (BATF) is a newly identified transcriptional factor regulating the differentiation of Th17 cells. However, its precise role in patients with chronic hepatitis B remains unclear. Sixty chronic hepatitis B (CHB) patients, twenty-two acute-on-chronic hepatitis B liver failure (ACHBLF) patients and seventeen healthy controls were included in our study...

To better clarify the clinical features and therapeutic strategy of CMV infection in lupus nephritis patients, we retrospectively surveyed a total of 40 lupus nephritis patients, who had been hospitalized and underwent renal biopsy and diagnosed as having CMV infection during their hospitalization at our institution within the last 10 years. The percentage of CMV infections in the entire hospitalized lupus nephritis population was 5.3% (40/755). The principal clinical features of the 40 CMV-infected patients were hematological disorders (n = 25), fever (n = 21), liver dysfunction (n = 19), and respiratory symptoms (n = 12)...

Thromboelastometry is increasingly used in the clinical and scientific setting. The use of frozen plasma samples may be useful in overcoming certain limitations such as local and timely availability. Whole blood (WB) samples of 20 healthy volunteers were obtained, and plasma was generated. NATEM (n = 20), EXTEM (n = 20) and INTEM (n = 8) analyses were performed in WB, fresh plasma and frozen and thawed plasma. Dabigatran (500, 1000 ng/ml), rivaroxaban (100, 200 ng/ml) or alteplase (333 ng/ml) were added ex vivo to WB, and thromboelastometry was performed in WB and in frozen and thawed plasma samples...

Accumulating evidence indicates that the success of cancer therapy depends not only on a combination of adequate procedures (surgery, chemotherapy and radiotherapy) that aim to eliminate all tumor cells, but also on the functional state of the host immune system. HLA and KIR molecules, in particular, are critical to the interactions between tumor cells and both innate and adaptive immune cells such as NK cells and T cells. Different KIR-HLA gene combinations as well as different HLA expression levels on tumor cells associate with variable tumor prognosis and response to treatment...

Adipocytokines are strongly associated with abdominal adiposity during the course of acute pancreatitis (AP). This study investigated associations between a panel of adipocytokines and abdominal adiposity in AP patients after hospital discharge, as well as the effect of several covariates. Fasting venous blood samples were collected to measure adiponectin, interleukin 6, leptin, monocyte chemoattractant protein 1, tumour necrosis factor α (TNFα), resistin, and retinol-binding protein 4. Waist circumference (WC), waist-hip ratio, and waist-height ratio (WheightR) were used as measures of abdominal adiposity...

Rheumatoid arthritis (RA) is a chronic disease affecting daily life of numerous patients, and uncontrolled proliferation of synovial fibroblasts plays vital role during the pathology of RA. Platelet-rich plasma (PRP), widely used in tissue regeneration and pain management, is rarely studied in RA. This study aims to investigate the effect of PRP on synovial fibroblasts during RA. Rheumatoid fibroblast-like synoviocyte MH7A cells were stimulated by lipopolysaccharide (LPS) to simulate RA conditions and treated with PRP, after that the concentration of inflammatory factors interleukin (IL) 1β, tumor necrosis factor alpha (TNFα) and IL6 in the supernatant of culture medium was quantified by ELISA...

Multiple myeloma (MM) is a complex disease and is presently an incurable malignant plasma cell tumor. Although the introduction of proteasome inhibitor and the immunomodulators markedly improved the effect of myeloma therapy, most patients still suffer from relapse even with an initially effective therapy. Accumulating evidence suggests that immunotherapy is a promising option in treating MM. And T cell plays crucial role through inducing sustained immune response in vivo in the immunotherapy of tumors. In this article, we will discuss progress of several T cell-based immunotherapies with insight into how they eradicate myeloma cells and their disadvantages...

Kawasaki disease (KD) arises due to the disorder of the inflammation response and faulty immune regulation. Interleukin-27 (IL-27) is a novel cytokine with both pro-inflammatory and anti-inflammatory effects. This study investigated the relationship between serum levels of IL-27, Interleukin-17A (IL-17A), Interleukin-10 (IL-10), Interleukin-6 (IL-6), Interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and coronary artery lesions (CALs) in patients with KD. We obtained blood samples from 81 children with KD before intravenous immunoglobulin (IVIG) therapy...

The spatial distribution of mast cells inside the tumor stroma has been little investigated. In this study, we have evaluated tumor mast cells (MCs) distribution in gastric cancer through the analysis of the morphological features of the spatial patterns generated by these cells, including size, shape, and architecture of the cell pattern. The pattern of distribution of tryptase- and chymase-positive MCs around the blood vessels and gastric glands in human gastric adenocarcinoma samples was investigated by immunohistochemical techniques and by introducing a quantitative approach to characterize the spatial distribution of MCs...

DNase1l3 is an endonuclease to degrade the chromatin of apoptotic or necrotic cells. Serum DNase1l3 may fulfill the function of clearance of chromatin released into the circulation by dying cells, which can trigger autoimmune responses. To date, it remains unclear whether serum DNase1l3 level associates with the pathogenesis of autoimmune diseases. Sixty-eight patients with dermatomyositis/polymyositis (DM/PM, n = 30), systemic lupus erythematosus (SLE, n = 20) and rheumatoid arthritis (RA, n = 18), as well as 26 healthy blood donors were enrolled in the present study...

Bruton's tyrosine kinase (BTK) is a cytoplasmatic protein that is part of the B-cell antigen receptor signaling pathway. Our aim was to evaluate the expression of BTK in B-cell neoplasms and compare it to normal B-cell lymphocytes. After surface staining with CD19 and CD45, flow cytometry staining for intracellular BTK was performed in leukemic or mature B-cells from bone marrow or peripheral blood samples. No differences in BTK expression were identified between groups, or in comparison to control samples, there was no association between BTK expression and the clinical variables evaluated...

Although papillary thyroid cancer is a relatively indolent malignancy, its progression may be associated with dedifferentiation and resistance to radioactive iodine treatment. In this study, patterns of differentially expressed genes in association with disease progression were systemically evaluated. We firstly performed transcriptome analyses for four matched cancerous and noncancerous tissue pairs of the classical subtype of papillary thyroid cancer. Among the upregulated and downregulated genes, the expression of 164 and 183 genes increased and decreased, respectively, from stage I to stage IV...

Rho-associated coiled-coil-containing protein kinase 2 (ROCK2) has been known as an effector for the small GTPase Rho and plays an important role in tumor progression and metastasis. However, the effect of ROCK2 in gastric cancer (GC) has not been identified. This study showed that ROCK2 expression significantly increased in clinical GC tissues compared with adjacent non-cancer tissues. Immunohistochemistrical analysis showed that high expression of ROCK2 was correlated with tumor grade, tumor-node-metastasis stage, infiltration depth, lymph node invasion and Ki-67, and predicted poor prognosis in 135 gastric cancer specimens...
