Long-term Immune Response to Hepatitis B Virus Vaccination Regimens in Adults With Human Immunodeficiency Virus 1: Secondary Analysis of a Randomized…

2016

International audience; IMPORTANCE:Data on long-term immune responses to hepatitis B virus (HBV) vaccination in adults with human immunodeficiency virus 1 (HIV-1) infection are scarce.OBJECTIVE:To compare long-term (up to month 42) immune responses to the standard HBV vaccination regimen with a 4-injection intramuscular double-dose regimen and a 4-injection intradermal low-dose regimen.DESIGN, SETTING, AND PARTICIPANTS:The phase 3, open-label, multicenter parallel-group (1:1:1 allocation ratio) randomized clinical trial was conducted from June 28, 2007, to October 23, 2008, at 33 centers in France. Participants included 437 HBV-seronegative adults with HIV-1 and CD4 cell counts of more than…

Treatment with albumin-hydroxyoleic acid complex restores sensorimotor function in rats with spinal cord injury: Efficacy and gene expression regulat…

2017

Sensorimotor dysfunction following incomplete spinal cord injury (SCI) is often characterized by paralysis, spasticity and pain. Previously, we showed that intrathecal (i.t.) administration of the albumin-oleic acid (A-OA) complex in rats with SCI produced partial improvement of these symptoms and that oral 2-hydroxyoleic acid (HOA, a non-hydrolyzable OA analogue), was efficacious in the modulation and treatment of nociception and pain-related anxiety, respectively. Here we observed that intrathecal treatment with the complex albumin-HOA (A-HOA) every 3 days following T9 spinal contusion injury improved locomotor function assessed with the Rotarod and inhibited TA noxious reflex activity in…

Neuroprotective potential of antihyperglycemic drug metformin in streptozocin-induced rat model of sporadic Alzheimer's disease.

2020

Abstract The earliest hallmarks of sporadic Alzheimer's disease (sAD) are impaired glucose metabolism, chronic neuroinflammation, diminished synaptic plasticity and subsequent cognitive decline. The safest antidiabetic drug metformin has shown both glucose metabolism-improving and cognition-enhancing action in type 2 diabetes patients and diabetic model animals. However, metformin has not been previously studied in intracerebroventricular streptozocin (STZ)-induced model of sAD. Therefore, our aim was to assess the preventive action of metformin in sAD model-rats. Firstly, the actions of metformin (75 and 100 mg/kg) on cognitive functions and sociability were examined. Secondly, we wanted t…

Activation of MORs in the VTA induces changes on cFos expression in different projecting regions: Effect of inflammatory pain.

2019

Abstract Chronic pain is a worldwide major health problem and many pain-suffering patients are under opioid based therapy. Epidemiological data show that pain intensity correlates with the risk of misuse of prescription opioids, and other drugs of abuse including alcohol. This increased vulnerability to suffer Substance Use Disorders could be, in part, caused by functional changes that occur over the mesocorticolimbic system, a brain pathway involved in reward processing and addiction. Previous data in rats revealed that inflammatory pain desensitizes mu opioid receptors (MORs) in the ventral tegmental area (VTA). As a consequence, pain alters dopamine release in the nucleus accumbens (NAc)…

Safety and efficacy of intra-articular anti-tumor necrosis factor α agents compared to corticosteroids in a treat-to-target strategy in patients with…

2015

The aim of this study was to assess safety and efficacy of ultrasonography (US)-guided intra-articular injections using tumor necrosis factor (TNF) blockers compared to corticosteroids in rheumatoid arthritis (RA) or psoriatic arthritis (PsA) patients, experiencing refractory monoarthritis despite the current systemic therapy. Eighty-two patients were randomized to receive three intra-articular injections monthly of either corticosteroid or TNF blockers. Primary endpoints were the safety and an improvement greater than 20% for visual analogic scales of involved joint pain in patients injected with anti-TNFα. Further clinical, US, and magnetic resonance imaging (MRI) evaluations were consid…

5-Fluorouracil and recombinant alpha interferon-2a in the treatment of advanced colorectal carcinoma: a dose optimization study

1990

A dose optimization study was carried out with the aim of identifying the maximally tolerated dose of recombinant alpha interferon-2a (raIFN-2a) in combination with 5-fluorouracil (5FU). 5FU was given at the dose of 750 mg/m2 over a 4-hour infusion on day 1- - greater than 5 followed by 750 mg/m2 weekly i.v. bolus. Recombinant aIFN-2a was started at 3 x 10(6) IU subcutaneously three times/week. 12 patients with advanced colorectal carcinoma were included in the study. 10 patients had previously received chemotherapy for advanced disease. Severe fatigue, most likely attributable to rIFN, was the dose-limiting toxicity. The dosage of raIFN-2a could not be further escalated above 12 x 10(6) IU…

Assessment of in vivo organ-uptake and in silico prediction of CYP mediated metabolism of DA-Phen, a new dopaminergic agent

2017

Abstract The drug development process strives to predict metabolic fate of a drug candidate, together with its uptake in major organs, whether they act as target, deposit or metabolism sites, to the aim of establish a relationship between the pharmacodynamics and the pharmacokinetics and highlight the potential toxicity of the drug candidate. The present study was aimed at evaluating the in vivo uptake of 2-Amino-N-[2-(3,4-dihydroxy-phenyl)-ethyl]-3-phenyl-propionamide (DA-Phen) − a new dopaminergic neurotransmission modulator, in target and non-target organs of animal subjects and integrating these data with SMARTCyp results, an in silico method that predicts the sites of cytochrome P450-m…

Embryo multinucleation at the two-cell stage is an independent predictor of intracytoplasmic sperm injection outcomes.

2016

European Guidelines (S1) on the use of high‐dose intravenous immunoglobulin in dermatology

2016

Background The treatment of severe dermatological autoimmune diseases and toxic epidermal necrolysis (TEN) with high-dose intravenous immunoglobulin (IVIg) is a well-established procedure in dermatology. As treatment with IVIg is usually considered for rare clinical entities or severe clinical cases, the use of immunoglobulin is not generally based on data from randomized controlled trials that are usually required for the practice of evidence-based medicine. Owing to the rarity of the indications for the use of IVIg, it is also unlikely that such studies will be available in the foreseeable future. Because the high costs of IVIg treatment also limit its first-line use, the first clinical g…
