Understanding the initiation, delivery and processing of bone cancer pain from the peripheral to the central nervous system.

Bone cancer pain is a complex condition characterized by persistent, sudden, spontaneous pain accompanied by hyperalgesia that typically ari … omal cells within the bone marrow release various chemical signals, including inflammatory factors, colony-stimulating factors, chemokines, and hydrogen ions. Consequently, the nociceptors located at the nerve endings within the bone marrow sense these chemical signals, generating electrical signals that are then transmitted to the brain through the spinal cord. Subsequentl …

Poor Renal Function and a High Modified Glasgow Prognostic Score Are Predictive Factors for Nedaplatin/5-Fluorouracil Combination Therapy-induced Febrile Neutropenia.

BACKGROUND/AIM: Nedaplatin (NDP)/5-fluorouracil (5-FU) combination therapy frequently causes severe neutropenia and febrile neutropenia (FN). However, there is no consensus on the risk factors for FN caused by NDP/5-FU combination therapy. Mouse models of cancer cachexia are known to be susceptible to infections. Conversely, the modified Glasgow prognostic score (mGPS) is believed to reflect cancer cachexia. We hypothesized that mGPS is a predictive factor for FN caused by NDP/5-FU combination therapy. PATIENTS AND METHODS: We analyzed the relationship between mGPS and FN in patients who rece

Plerixafor use in autologous hematopoietic stem cell mobilization: Experience from a single center in Southern India.

BackgroundPlerixafor is used for patients at risk of Stem cell mobilization failure based on clinical factors or low peripheral blood CD34 count. It is also added upfront to any mobilization irrespective of risk factor, but the cost-effectiveness of the approach is an issue. Data on plerixafor in different settings of autologous hematopoietic stem cell (HSC) collection from India are scant. We are hereby reporting the experience of failure/success of mobilization rate and few important significant variables (CD34+ dosage, failed collection) between plerixafor and granulocyte colony-stimulating

Association Between Myasthenia Gravis and Systemic Lupus Erythematosus as a Comorbid State.

Systemic lupus erythematosus (SLE) and myasthenia gravis (MG) are autoimmune states which have presentational similitude. Both conditions test serologically positive for anti-nuclear antibodies and require exceptional differential diagnostic acumen to segregate one from the other. The hypothesized factors provoking these diseases may be immunological, genetic, hormonal, or environmental and can be better understood by large-scale controlled epidemiological studies. Biochemical factors such as variation in CXC (an α chemokine subfamily), CXCL13, and granulocyte-macrophage colony-stimulating fac

Review: Relationships between metabolism and neutrophil function in dairy cows in the peripartum period.

Aspects of neutrophil function are diminished or dysregulated in dairy cows in the weeks just before and after calving, which appears to be an important contributor to the occurrence of retained placenta, mastitis, metritis and endometritis. The timing and mechanisms by which specific elements of neutrophil function are impaired are only partially understood. Oxidative burst capacity is the element of neutrophil function most consistently shown to be impaired in the week after calving, but that observation may partially be biased because oxidative burst has been studied more than other functio

Crohn's disease: a review of current treatment with a focus on biologics.

Crohn's disease is a debilitating and expensive disease that is growing in incidence in both developing and developed countries. While conve … ti-inflammatory cytokines, agents that target pro-inflammatory cytokines and granulocyte-macrophage colony-stimulating factors. Further prospective studies will provide interesting insight into different mechanisms by which factors involved in the pathophysiology of Crohn's disease can be modulated.

Beneficial effects of hematopoietic growth factor therapy in chronic ischemic stroke in rats.

BACKGROUND AND PURPOSE: Stroke is the leading cause of adult disability worldwide. Currently, there is no effective treatment for stroke survivors. Stem cell factor (SCF) and granulocyte-colony stimulating factor (G-CSF) are the growth factors regulating hematopoiesis. We have previously observed that SCF and G-CSF have neuroprotective and functional effects on acute brain ischemia. In the present study, the beneficial effects of SCF and G-CSF on chronic brain ischemia were determined. METHODS: SCF, G-CSF, or SCF+G-CSF was administered subcutaneously to rats 3.5 months after induction of isch

Severe mucositis is associated with reduced survival after autologous stem cell transplantation for lymphoid malignancies.

Mucositis is a known complication of autologous stem cell transplantation (ASCT). This study retrospectively reviewed 191 patients with lymphoid malignancies undergoing ASCT following a uniform mobilising regimen of etoposide (VP-16)/granulocyte colony-stimulating factor and a uniform high-dose preparative regimen of busulfan/cyclophosphamide/VP-16. Eighty-seven patients experienced severe mucositis (modified Oral Mucositis Assessment Scale > or =1). Patient characteristics compared between mucositis groups were balanced according to disease status, prior exposure to radiation therapy, time fr

Past and current theories of etiology of IBD: toothpaste, worms, and refrigerators.

While tremendous advances have improved the understanding of inflammatory bowel disease, with regard to environmental risk factors as well as the biochemical nature of the inflammatory process, a determination of primary etiology remains elusive. Numerous theories have been proposed in the past century concerning the cause of Crohn's disease and ulcerative colitis with implications for specific therapies. On further study, most of these ideas and therapies have failed to be accurate in theory or therapeutic approach. Others remain untested or are the focus of current investigation and controve

Human growth factor-enhanced regeneration of transplantable human hematopoietic stem cells in nonobese diabetic/severe combined immunodeficient mice.

Self-renewal is considered to be the essential defining property of a stem cell. Retroviral marking, in vitro amplification, and serial transplantation of human cells that can sustain long-term lymphomyelopoiesis in vivo have provided evidence that human hematopoietic stem cell self-renewal occurs both in vitro and in vivo. To investigate whether this process can be manipulated by cytokines, we administered two different combinations of human growth factors to sublethally irradiated nonobese diabetic/severe combined immunodeficient (SCID) mice transplanted with 10(7) light-density human cord b

Complement Activation Fragments in Cervicovaginal Fluid Are Associated with Intra-Amniotic Infection/Inflammation and Spontaneous Preterm Birth in Women with Preterm Premature Rupture of Membranes.

OBJECTIVE: We sought to determine whether the levels of complement and other inflammatory and angiogenic mediators in cervicovaginal fluid (CVF) are independently associated with intra-amniotic infection and/or inflammation (IAI) and imminent spontaneous preterm birth (SPTB, £48 hours of sampling) in women with preterm premature rupture of membranes (PPROM). STUDY DESIGN: This was a retrospective study consisting of 85 singleton pregnant women with PPROM at 200/7 to 336/7 weeks. Amniotic fluid (AF) obtained via amniocentesis was cultured and assayed for interleukin-6. CVF samples collected at

Neer Award 2015: Analysis of cytokine profiles in the diagnosis of periprosthetic joint infections of the shoulder.

BACKGROUND: Periprosthetic joint infection (PJI) after shoulder arthroplasty can present a diagnostic and therapeutic challenge. This study evaluated the diagnostic utility of broader synovial fluid cytokine analysis for identifying PJI in patients undergoing revision shoulder arthroplasty. METHODS: Synovial fluid levels of 9 cytokines (interleukin [IL] 6, granulocyte-macrophage colony-stimulating factor, IL-1β, IL-12, IL-2, IL-8, interferon-γ, IL-10, and tumor necrosis factor-α) were measured in 75 cases of revision shoulder arthroplasty with a multiplex immunoassay. Cases were classified in

Salivary cytokine levels in subjects with chronic periodontitis and in periodontally healthy individuals: a cross-sectional study.

BACKGROUND AND OBJECTIVE: Saliva has been proposed as a noninvasive diagnostic fluid that could be used in the diagnosis of oral and systemic diseases. The levels of salivary biomarkers, such as cytokines, could potentially be used as a surrogate to distinguish periodontally healthy individuals from subjects with periodontitis. Therefore, the goal of the present investigation was to determine if the levels of 10 different cytokines in saliva differed between a group of periodontally healthy individuals and a group of subjects with periodontitis. Correlations between the concentrations of these

[Cytokine therapy].

Cytokines, mediators of intercellular communication, penetrate as a new therapeutic group in to haematology, oncology, immunology and other disciplines. Recently two main spheres of indication of wider clinical use are in the foreground: 1. treatment of leukaemias and advanced solid tumours (interferons, interleukin-2, tumour-necrosis factor and others) and 2. treatment of impaired haematopoiesis (in clinical practice in particular erythropoietin, granulocyte-macrophage and granulocyte colonies stimulating factor). Other possibilities are offered by cytokines in the treatment of viral diseases

Cytokine-induced expression of CD1b molecules by peripheral blood monocytes: influence of 3'-azido-3'-deoxythymidine.

CD1b is a nonpolymorphic, MHC-like molecule, capable of presenting non-peptide antigens (Ags) to CD3+, CD4-, CD8-, alphabeta or gammadelta T lymphocytes. Previous studies have shown that CD1b can be induced in monocytes/macrophages by GM-CSF+IL-4, and can restrict their presentation of Mycobacterium tuberculosis antigen (Ag) to Ag-specific T cells. Since a number of HIV-positive subjects undergo mycobacterial infections, preliminary studies have been performed to explore whether anti-HIV chemotherapy would influence cytokine-induced CD1b expression in peripheral blood monocytes. The results ob

Luteal phase support for in vitro fertilization-embryo transfer--present and future methods to improve successful implantation.

PURPOSE: To present reasons for luteal phase deficiency when taking controlled ovarian hyperstimulation (COH) for purposes of inducing multiple oocytes for in vitro fertilization (IVF), and to suggest strategies to overcome the defect. METHODS: Treatment options presented include luteal phase support with human chorionic gonadotropin (hCG) injection, progesterone, estradiol, gonadotropin releasing hormone agonists, cytokines, e.g., granulocyte colony stimulating factor, and lymphocyte immunotherapy. RESULTS: hCG and progesterone produce the best results and are comparable or at best a slight

Regulatory T cells induced by GM-CSF suppress ongoing experimental myasthenia gravis.

We had previously observed that treatment utilizing granulocyte-macrophage colony-stimulating factor (GM-CSF) had profound effects on the induction of experimental autoimmune myasthenia gravis (EAMG), a well-characterized antibody-mediated autoimmune disease. In this study, we show that EAMG induced by repeated immunizations with acetylcholine receptor (AChR) protein in C57BL6 mice is effectively suppressed by GM-CSF treatment administered at a stage of chronic, well-established disease. In addition, this amelioration of clinical disease is accompanied by down-modulation of both autoreactive T

Juvenile myelomonocytic leukemia characterized by cutaneous lesion containing Langerhans cell histiocytosis-like cells.

We present a 1-year-old boy who developed a cutaneous lesion on the trunk and hepatosplenomegaly. Laboratory examination showed leukocytosis with peripheral blasts, atypical monocytosis, anemia, hyper IgG, and a mild elevation of C-reactive protein. Clinical features and skin biopsy findings matched the diagnostic criteria of both juvenile myelomonocytic leukemia (JMML) and Langerhans cell histiocytosis (LCH). Histopathology revealed atypical mononuclear cells that had infiltrated around vessels throughout the dermis in a skin biopsy specimen. These cells were CD1a (+), S-100 (+), CD68 (+), CD

Growth factor supportive care for chemotherapy-induced neutropenia suppresses antitumour immunity in checkpoint blockade-responsive pancreatic cancer.

INTRODUCTION: Growth factors, including granulocyte colony-stimulating factor (G-CSF; pegfilgrastim, filgrastim), are used for prophylaxis or treatment of chemotherapy-induced neutropenia, yet their effects on antitumour immunity remain incompletely understood. We previously found that serum from patients with pancreatic ductal adenocarcinoma (PDAC) treated with multiagent chemotherapy plus G-CSF drove differentiation of T cell-suppressive monocytes in vitro, suggesting that supportive care interventions may shape immune responses in this disease. METHODS: We evaluated the immunologic and the
