Here we report the first case of neutrophilic dermatoses related to a granulocyte colony-stimulating factor (GCSF)-producing solid pseudopapillary tumour (SPT). The patient was a 39-year-old woman presenting with scattered pustules and crusts of the palms/heels/thighs and plaques of the bilateral lower legs. The skin biopsy revealed dense neutrophil infiltration in the epidermis to the corium. A pancreatic head tumour was detected on computed tomography. A pathological examination of the resected specimen suggested a SPT...

BACKGROUND: Chronic inflammation and oxidative stress are hallmarks of chagasic cardiomyopathy (CCM). In this study, we determined if microparticles (MPs) generated during Trypanosoma cruzi (Tc) infection carry the host's signature of the inflammatory/oxidative state and provide information regarding the progression of clinical disease. METHODS: MPs were harvested from supernatants of human peripheral blood mononuclear cells in vitro incubated with Tc (control: LPS treated), plasma of seropositive humans with a clinically asymptomatic (CA) or symptomatic (CS) disease state (vs...

BACKGROUND: Acute systemic inflammatory response syndrome arising from infection can lead to multiple organ failure and death, with greater susceptibility occurring in immunocompromised individuals. Moreover, sub-acute chronic inflammation is a contributor to the pathology of diverse degenerative diseases (Parkinson's disease, Alzheimer's disease and arthritis). Given the known limitations in Western medicine to treat a broad range of inflammatory related illness as well as the emergence of antibiotic resistance, there is a renewed interest in complementary and alternative medicines (CAMs) to achieve these means...

BACKGROUND: Myelotoxic chemotherapy is associated with chemotherapy-induced (febrile) neutropenia (CIN/FN). The MONITOR-GCSF study evaluated biosimilar filgrastim (Zarzio®) prophylaxis patterns, associated outcomes, and determinants. We performed stratified analyses comparing elderly and non-elderly patients. METHODS: Comparative (elderly/non-elderly) analysis of demographics and clinical status, prophylaxis, associated CIN/FN outcomes (CIN grade 4 [CIN4], FN, CIN/FN-related hospitalizations and chemodisturbances, composite), and, per hierarchical modeling, determinants thereof evaluated at the patient- and cycle-level...

Given the increasing prevalence of metabolic syndrome (MetS) in males of reproductive age, the objective of this prospective case-controlled study was to investigate the impact of subacute systemic inflammation associated with MetS on seminal cytokines and standard sperm parameters in comparison with healthy men. Between 2011 and 2014, we recruited 27 patients with MetS out of 41 obese patients screened from an internal outpatient clinic. Twenty-seven age-matched healthy controls were enrolled from 54 men requesting vasectomy in a urological outpatient clinic...

BACKGROUND: Risk models of chemotherapy-induced (CIN) and febrile neutropenia (FN) have to date focused on determinants measured at the start of chemotherapy. We extended this static approach with a dynamic approach of CIN/FN risk modeling at the start of each cycle. DESIGN: We applied predictive modeling using multivariate logistic regression to identify determinants of CIN/FN episodes and related hospitalizations and chemotherapy disturbances (CIN/FN consequences) in analyses at the patient ('ever' during the whole period of chemotherapy) and cycle-level (during a given chemotherapy cycle)...

Neutrophils generated by granulocyte colony-stimulating factor (GCSF) are functionally immature and, consequently, cannot effectively reduce infection and infection-related mortality in cancer chemotherapy-induced neutropenia (CCIN). Am80, a retinoic acid (RA) agonist that enhances granulocytic differentiation by selectively activating transcription factor RA receptor alpha (RARα), alternatively promotes RA-target gene expression. We found that in normal and malignant primary human hematopoietic specimens, Am80-GCSF combination coordinated proliferation with differentiation to develop complement receptor-3 (CR3)-dependent neutrophil innate immunity, through altering transcription of RA-target genes RARβ2, C/EBPε, CD66, CD11b, and CD18 This led to generation of functional neutrophils capable of fighting infection, whereas neutralizing neutrophil innate immunity with anti-CD18 antibody abolished neutrophil bactericidal activities induced by Am80-GCSF Further, Am80-GCSF synergy was evaluated using six different dose-schedule-infection mouse CCIN models...

We report here the largest study to date of adult patients with acute myeloid leukemia (AML) tested for measurable residual disease (MRD) at the time of autologous hematopoietic cell transplantation (auto-HCT). Seventy-two adult patients who underwent transplantation between 2004 and 2013 at a single academic medical center (University of California San Francisco) were eligible for this retrospective study based on availability of cryopreserved granulocyte colony-stimulating factor (GCSF)-mobilized autologous peripheral blood progenitor cell (PBPC) leukapheresis specimens ("autografts")...

Ischemic stroke elicits a prompt inflammatory response that is characterized by a well-timed recruitment of peripheral immune cells to the brain. Among these, monocytes play a particularly important, but multifaceted role and have been increasingly recognized to affect stroke outcome. Granulocyte colony stimulating factor (GCSF) is known for its immunosuppressive actions on mononuclear cells, but previous studies in the stroke field were mainly confined to its neuroprotective actions. Herein, we investigated whether GCSF affects post-stroke inflammation in a mouse model of focal brain ischemia by modulating monocyte responses...

We carried out post-transplantation cyclophosphamide (PTCy)-based haploidentical peripheral blood stem cell transplantation in 51 patients with refractory/relapsed acute myeloid leukemia not in remission. The first 10 patients received nonmyeloablative conditioning followed by planned granulocyte colony-stimulating factor (G-CSF)-mobilized donor lymphocyte infusions (DLIs) on days 35, 60, and 90. No patient developed graft-versus-host disease (GVHD), but 90% had disease progression between 3 and 6 months. A subsequent 41 patients received myeloablative conditioning (MAC); the first 20 patients did not receive DLIs (MAC group) and the next 21 patients received G-CSF-mobilized DLIs (G-DLI) on days 21, 35, and 60 (MAC-DLI group)...

The neural crest is a population of cells in the vertebrate embryo that gives rise to a wide range of tissues and cell types, including components of the peripheral nervous system and the craniofacial skeleton as well as melanocytes and the adrenal medulla. Aberrations in neural crest development can lead to numerous diseases, including cancers such as melanoma and neuroblastoma. Cancer stem cells (CSCs) have been identified in these neural crest-derived tumors, and these CSCs demonstrate resistance to treatment and are likely key contributors to disease relapse...

Dental tissue is emerging as a promising source of stem cells especially in nerve regeneration mainly due to their neural origin and ease of harvest. We isolated dental stem cells from three sources, namely, dental pulp (DPSCs), dental follicle (DFSCs), and apical papilla (SCAP), and explored the efficacy of each towards neural differentiation in comparison to bone marrow-derived stem cells. The neural differentiation potential was assessed by expression of various neural markers and neurosphere assay. We observed that DPSCs were inherently predisposed towards neural lineage...

BACKGROUND: The expiry of patents for costly biologics is creating new momentum on the pharmaceutical market for biosimilars (copies of off-patent biologics) and paving the way for their development. However, little is known about the competitiveness of biosimilars versus their originators and other biologics belonging to the same therapeutic class. OBJECTIVE: The main goal of this study was to analyse the type of competition generated by the first biosimilars commercialised on key global biologic markets and to grasp their economic model...

Neutropenic patients with malignancies and hematopoietic stem cell transplant recipients are prone to severe infections. Reversal of neutropenia with granulocyte transfusion (GTX) from donors stimulated with GCSF with/without steroids aims to improve outcome of infection. Cochrane analysis of randomized controlled studies, however, failed to show reduced mortality following GTX in conjunction with antibiotics. Non-randomized studies published during the last 20 years produced a very broad spectrum of results...

We present here an approach to non-covalently combine an engineered model protein with a PEGylated peptide via coiled-coil binding. To this end a fusion protein of G-CSF and the peptide sequence (JunB) was created-one sequence of JunB was expressed at the N-terminal of GCSF. JunB is able to bind to the peptide sequence cFos, which was in turn covalently linked to a chain of poly(ethylene glycol) (PEG). The selected peptide sequences are leucine zipper motives from transcription factors and are known to bind to each other specifically by formation of a super secondary structure called coiled-coil...

The biosimilar industry is witnessing an unprecedented growth with the newer therapeutics increasing in complexity over time. A key step towards development of a biosimilar is to establish analytical comparability with the innovator product, which would otherwise affect the safety/efficacy profile of the product. Choosing appropriate analytical tools that can fulfil this objective by qualitatively and/or quantitatively assessing the critical quality attributes (CQAs) of the product is highly critical for establishing equivalence...

BACKGROUND: Granulocyte Colony Stimulating Factors (GCSF) is high-cost agents commonly recommended for primary and secondary prophylaxis of chemotherapy-induced neutropenia and febrile neutropenia. GCSFs have been shown to be beneficial in some patient subgroups, although they are probably overused in clinical settings. The American Society of Clinical Oncology (ASCO) guidelines summarize current data on the appropriate use of CSFs. The aim of this study was to assess and audit the use of GCSF in a tertiary care center according to the recommendation of ASCO guideline...
