: Acute-on-chronic liver failure (ACLF) in cirrhosis is an increasingly recognized syndrome characterized by acute decompensation, organ failure(s) and high short-term mortality. Recent findings suggest that an over-exuberant systemic inflammation plays a primary role in ACLF progression. In this study, we examined whether genetic factors shape systemic immune responses in patients with decompensated cirrhosis. Six single nucleotide polymorphisms (SNPs) in inflammation-related genes (IL-1β: rs1143623, IL-1ra: rs4251961, IL-10: rs1800871, SOCS3: rs4969170, NOD2: rs3135500 and CMKLR1: rs1878022) were genotyped in 279 cirrhotic patients with (n=178) and without (n=101) ACLF from the CANONIC study of the CLIF consortium...

Diabetes induces a decrease in the number and function of different pro-angiogenic cells types generically designated as putative endothelial progenitor cells (EPC), which encompasses cells from myeloid origin that act in a paracrine fashion to promote angiogenesis and putative "true" EPC that contribute to endothelial replacement. This not only compromises neovasculogenesis in ischemic tissues but also impairs, at an early stage, the reendotheliziation process at sites of injury, contributing to the development of endothelial dysfunction and cardiovascular complications...

G-CSF is a hematopoietic growth factor that regulates the proliferation, differentiation and survival of myeloid lineage cells, which has protective effects in autoimmune neuroinflammatory diseases such as EAE. Here we use EAE model treated by G-CSF to address the hypothesis that G-CSF inhibits the proliferative response of splenic T cells via the enhancement of apoptosis, and this priming effect of G-CSF depends on the cell cycle. Our results show that G-CSF administration reduced EAE frequency and severity of attacks...

The intrathecal space has become an important anatomic site for medical intervention not only in anesthesia practice, but also in many other medical specialties. Undesired/inadvertent intrathecal injections (UII) are generally rare. There is tremendous variation in reported inadvertent administrations via an intrathecal route in the literature, mainly as individual cases and very small case-series reports. This review aims to identify potential sources of UII, its clinical presentations, and appropriate management...

OBJECTIVE: To characterize changes in myeloid and lymphoid innate immune cells in patients with relapsing-remitting multiple sclerosis (MS) during a 6-month follow-up after alemtuzumab treatment. METHODS: Circulating innate immune cells including myeloid cells and innate lymphoid cells (ILCs) were analyzed before and 6 and 12 months after onset of alemtuzumab treatment. Furthermore, a potential effect on granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-23 production by myeloid cells and natural killer (NK) cell cytolytic activity was determined...

BACKGROUND: Ionic contrast, if accidentally injected into the intrathecal space during routine imaging studies or interventional procedures, may significantly interfere with neuronal activity, potentially causing ascending tonic-clonic seizure syndrome and even death. As a result, ionic contrast is strictly contraindicated for intrathecal use. Rapid recognition of the condition followed by prompt management, typically involving aggressive cerebrospinal fluid (CSF) drainage, is critical to improving patient outcome...

Sirtuin proteins have a variety of intracellular targets, thereby regulating multiple biological pathways including neurodegeneration. However, relatively little is currently known about the role or expression of the 7 mammalian sirtuins in the central nervous system. Western blotting, PCR and ELISA are the main techniques currently used to measure sirtuin levels. To achieve sufficient sensitivity and selectivity in a multiplex-format, a targeted mass spectrometric assay was developed and validated for the quantification of all seven mammalian sirtuins (SIRT1-7)...

OBJECTIVES: The neurobiological underpinnings of bipolar I disorder are not yet understood. Previous structural neuroimaging studies of bipolar disorder have produced rather conflicting results. We hypothesize that clinical sub-phenotypes of bipolar I disorder defined by their psychotic symptoms, especially those with mood-incongruent psychotic features, may have more extensive structural brain abnormalities. METHODS: We investigated structural brain alterations in patients with first-episode mania (n = 55) with mood-congruent (n = 16) and mood-incongruent (n = 32) psychotic features, as well as those without psychotic symptoms (n = 7), relative to healthy subjects (n = 56)...

BACKGROUND AND OBJECTIVE: Reduced progranulin levels are a hallmark of frontotemporal dementia (FTD) caused by loss-of-function (LoF) mutations in the progranulin gene (GRN). However, alterations of central nervous progranulin expression also occur in neurodegenerative disorders unrelated to GRN mutations, such as Alzheimer's disease. We hypothesised that central nervous progranulin levels are also reduced in GRN-negative FTD. METHODS: Progranulin levels were determined in both cerebrospinal fluid (CSF) and serum in 75 subjects (37 FTD patients and 38 controls)...

Infection-associated inflammatory stress during pregnancy is the most common cause of fetal growth restriction and/or miscarriage. Treatment strategies for protection of at-risk mothers are limited to a narrow range of vaccines, which do not cover the bulk of the common pathogens most frequently encountered. Using mouse models, we demonstrate that oral treatment during pregnancy with a microbial-derived immunomodulator (OM85), currently used clinically for attenuation of infection-associated airway inflammatory symptoms in infants-adults, markedly reduces risk for fetal loss/growth restriction resulting from maternal challenge with bacterial lipopolysaccharide or influenza...

Maternally Derived Antibodies (MDA) can have a negative effect on the efficacy of live attenuated vaccines against classical swine fever (CSF). For this reason, a marker vaccine candidate CP7_E2alf was tested for its efficacy in the presence of MDA. Pregnant sows were vaccinated four weeks before farrowing with CSF virus (CSFV) strain "Thiverval". A total of 40 piglets with MDAs were included in this study. At six weeks of age the piglets were allocated into three treatment groups using generalized randomized block design (GRBD) blocking on serological status and pen location...

BACKGROUND: Neurodegeneration plays a major role in determining disability in multiple sclerosis (MS) patients. Hence, there is increasing need to identify reliable biomarkers, which could serve as prognostic measure of disease progression. OBJECTIVES: To assess whether cerebrospinal fluid (CSF) tau and β-amyloid (Aβ) levels were altered in newly diagnosed MS patients and correlated with disability. Moreover, we investigated whether these CSF biomarkers associate with macroscopic brain tissue damage measures...

We have developed a novel real-time quaking-induced conversion RT-QuIC-based assay to detect alpha-synuclein aggregation in brain and cerebrospinal fluid from dementia with Lewy bodies and Parkinson's disease patients. This assay can detect alpha-synuclein aggregation in Dementia with Lewy bodies and Parkinson's disease cerebrospinal fluid with sensitivities of 92% and 95%, respectively, and with an overall specificity of 100% when compared to Alzheimer and control cerebrospinal fluid. Patients with neuropathologically confirmed tauopathies (progressive supranuclear palsy; corticobasal degeneration) gave negative results...

BACKGROUND: Intractable bone pain is a notorious adverse effect of granulocyte-colony stimulating factors (G-CSFs), such as pegfilgrastim and filgrastim, which are given to help prevent neutropenia in patients who are undergoing chemotherapy. G-CSF-induced bone pain is surprisingly common and often refractory to treatment with conventional analgesics. CASE REPORT: This article describes an emergency department case of opiate and nonsteroidal anti-inflammatory drug-resistant pegfilgrastim-induced bone pain that was successfully alleviated with 10 mg of oral loratadine, allowing for discharge home...
