Over
the last decades, the scientific interest in chemistry and pharmacology of
cannabinoids has increased. Most attention has focused on ∆9-tetrahydrocannabinol
(∆9-THC) as it is the psychoactive constituent of Cannabis sativa
(C. sativa). However, in previous years, the focus of interest in the second
plant constituent with non-psychotropic properties, cannabidiol (CBD) has been
enhanced. Recently, several groups have investigated the pharmacological
properties of CBD with significant findings; furthermore, this compound has
raised promising pharmacological properties as a wake-inducing drug. In the
current review, we will provide experimental evidence regarding the potential
role of CBD as a wake-inducing drug. 相似文献

Background:
Dimethyl fumarate (BG-12, Tecfidera®) is a new oral drug approved by FDA and EMA in March 2013 for relapsing – remitting multiple sclerosis (RRMS). The drug was much anticipated because of its possible superiority over currently available medications: fingolimod and teriflunomide as the only MS treatments currently available in oral form.Objective:
The aim of this systematic review with meta-analysis was to assess the efficacy and safety of BG-12 in the treatment of RRMS.Methods:
A systematic literature search was conducted in Medline/PubMed, EMBASE, and Cochrane Library up till 3rd November, 2013. We sought all published randomized clinical trials evaluating the use of dimethyl fumarate for the treatment of patients with RRMS. All included studies were critically appraised and analyzed with the use of Review Manager 5.1.0. software according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement protocol.Results:
Two trials, DEFINE and CONFIRM involved 2 651 patients and compared dimethyl fumarate taken either two or three times daily with placebo in patients with RRMS. Additionally in CONFIRM trial third group of patients received glatiramer acetate. The overall results of the meta-analysis showed that BG-12 (at both dosages) given to patients with RRMS is safe and statistically significantly more effective than placebo in reducing the proportion of patients who had a relapse by 2 years, the rate of disability progression and the mean number of gadolinium-enhancing lesions at 2 years. The comparison between BG-12 and glatiramer acetate revealed that the analyzed agent could potentially be more effective in the treatment of RRMS.Conclusions:
Despite limited RCTs data available, both analyzed BG-12 regimens showed their efficacy on clinical disease parameters and other measures of disease activity in RRMS. The safety profile of the study agent was acceptable. 相似文献4.

The role of gut microbiota in health and diseases has been receiving increased attention recently. Emerging evidence from previous studies on gut-microbiota-brain axis highlighted the importance of gut microbiota in neurological disorders. Multiple sclerosis (MS) is a chronic, inflammatory, demyelinating disease of the central nervous system (CNS) resulting from T-cell-driven, myelin-directed autoimmunity. The dysbiosis of gut microbiota in MS patients has been reported in published research studies, indicating that gut microbiota plays an important role in the pathogenesis of MS. Gut microbiota have also been reported to influence the initiation of disease and severity of experimental autoimmune encephalomyelitis, which is the animal model of MS. However, the underlying mechanisms of gut microbiota involvement in the pathogenesis of MS remain unclear. Therefore, in this review, we summerized the potential mechanisms for gut microbiota involvement in the pathogenesis of MS, including increasing the permeability of the intestinal barrier, initiating an autoimmune response, disrupting the blood-brain barrier integrity, and contributing to chronic inflammation. The possibility for gut microbiota as a target for MS therapy has also been discussed. This review provides new insight into understanding the role of gut microbiota in neurological and inflammatory diseases. 相似文献

Epstein–Barr virus (EBV) infection results in a life-long persistence of the virus in the host’s B-lymphocytes and has been
associated with numerous cancers including Burkitt’s lymphoma, Hodgkin lymphoma, and nasopharyngeal carcinoma. There is considerable
evidence that EBV infection is a strong risk factor for the development of multiple sclerosis. Early age at primary EBV infection
is typically asymptomatic, but primary infection during adolescence or adulthood often manifests as infectious mononucleosis,
which has been associated with a two- to threefold increased risk of MS. Most importantly, MS risk is extremely low in individuals
who are EBV negative, but it increases several folds following EBV infection. Additional evidence supporting a role for EBV
in MS pathogenesis includes the observations of elevated antibodies to EBV antigens (especially EBV nuclear antigen-1) prior
to the onset of MS, and an increased risk of MS among EBV-positive children. The biological mechanism by which EBV may cause
MS is not known, but several possibilities are discussed. 相似文献

Objective
To review the published literature on the efficacy of ketamine for the treatment of suicidal ideation (SI).Methods
The PubMed and Cochrane databases were searched up to January 2015 for clinical trials and case reports describing therapeutic ketamine administration to patients presenting with SI/suicidality. Searches were also conducted for relevant background material regarding the pharmacological function of ketamine.Results
Nine publications (six studies and three case reports) met the search criteria for assessing SI after administration of subanesthetic ketamine. There were no studies examining the effect on suicide attempts or death by suicide. Each study demonstrated a rapid and clinically significant reduction in SI, with results similar to previously described data on ketamine and treatment-resistant depression. A total of 137 patients with SI have been reported in the literature as receiving therapeutic ketamine. Seven studies delivered a dose of 0.5 mg/kg intravenously over 40 min, while one study administered a 0.2 mg/kg intravenous bolus and another study administered a liquid suspension. The earliest significant results were seen after 40 min, and the longest results were observed up to 10 days postinfusion.Conclusion
Consistent with clinical research on ketamine as a rapid and effective treatment for depression, ketamine has shown early preliminary evidence of a reduction in depressive symptoms, as well as reducing SI, with minimal short-term side effects. Additional studies are needed to further investigate its mechanism of action, long-term outcomes, and long-term adverse effects (including abuse) and benefits. In addition, ketamine could potentially be used as a prototype for further development of rapid-acting antisuicidal medication with a practical route of administration and the most favorable risk/benefit ratio. 相似文献10.
Multiple sclerosis (MS) is a chronic inflammatory autoimmune demyelinating disease of the central nervous system. It affects approximately 400,000 people in the United States and onset is usually during young adulthood. There are four clinical forms of MS, of which relapsing remitting type is the most common. As the etiology of MS is unknown, finding a cure will remain challenging. The main mechanism of injury appears to be inflammation and 8 agents are now FDA approved to help control MS. These agents for relapsing forms of MS target different parts of the immune system, with the end goal of decreasing and avoiding further inflammation. No agents are FDA approved for the primary progressive version of MS. FDA approved agents include four preparations of interferon β (Avonex, Rebif, Betaseron and Extavia), glatiramer acetate (Copaxone), mitoxantrone (Novantrone), natalizumab (Tysabri) and fingolimod (Gilenya). There are several drug undergoing phase II and III trials. The heterogeneity of the MS disease process, individual patient response, and medication toxicities continue to challenge the treating physician. 相似文献

The goal of pharmacogenetics is to identify "genetic fingerprints" that may predict a patient's response to pharmaceutical treatment. The use of pharmacogenetics replaces the trial-and-error strategy, which governs much of our clinical decision-making regarding treatment allocation in current medical practice, with individually tailored therapy. We review a pharmacogenetic research model, which implements high-throughput single nucleotide polymorphism technology to establish the correlation between drug-responsiveness and genetic polymorphisms of Copaxone(R)-treated multiple sclerosis patients. Implementation of similar pharmacogenetic approaches may promote the development of personalized medicine in multiple sclerosis as well as in other diseases. (c) 2002 Prous Science.

Multiple sclerosis is an autoimmune disease of the central nervous system (CNS) that leads to changes of nerve conduction due to damage of CNS– resident cells, primarily oligodendrocytes and neurons. CD4+ T cells are of primary importance in the immune cascades leading to tissue damage, but also CD8+ T cells, NK cells and B cells and antibodies contribute to tissue damage. In addition, the innate immune response and mainly microglial cells participate in the events leading to lesions. There are different types of MS and possibly this is due to different underlying immune mechanisms. The current treatment options mainly affect the immune response but have not much influence on secondary signaling changes in astrocytes and neurons which contribute to constant disease progression. The immune response in MS must be seen in the systemic context and there are strong indications that the gut and lung immunity affect MS disease precipitation. The strongest genetic influence in MS is mediated by the HLA class II genes and in Western Europeans and North Americans the disease is associated with HLA–DR2b. Possibly this is due to presentation of a set of specific antigens in context of this HLA allele. Novel data indicates that the immune response in MS is not only focused on certain myelin proteins like myelin basic protein (MBP) but to additional astrocytic and neuronal proteins, which is also mirrored in the pathology. While in the past the disease has been considered as mainly a white matter disease, nowadays it is clear that also grey matter is affected by the aberrant immune response. Still much needs to be learned regarding the underlying events in MS. This expanded knowledge is important to finally discover curative therapies. 相似文献

多发性硬化(multiple sclerosis,MS)是以中枢神经系统白质炎性脱髓鞘为主要表现的慢性自身免疫性疾病,是导致年轻患者非创伤性致残最常见的神经系统疾病。2003 年芬兰流行病学调查显示,如未进行有效干预,18~64岁MS患者中完全失去工作能力者可达45%[1] 。2012年全球MS患者已超过210万,2%~10%的MS患者起病于18周岁以前[2-3] 。与成年患者相比,儿童时期起病的MS患者更早出现复发,且复发频率更重,比成人患者平均提前约10年出现躯体残疾。此外,MS患儿可早期出现认知障碍,据报道大约35%的MS患儿诊断时即存在认知功能受损,起病5年内有50%以上的患儿可发生包括语言能力在内的全面认知能力下降[4]。故儿童MS对患儿生活质量与社会医保体系造成巨大影响,如何对MS患儿进行早期及有效干预值得小儿神经病学领域高度关注。 相似文献

The aim of the current research was to evaluate the immunomodulatory potential of methanol extract of Aegle marmelos in an experimental animal model of cellular and humoral immunity. Administration of methanol extract of Aegle marmelos (500 and 1000 mg/kg, p.o.) and Ocimum sanctum (100 mg/kg, p.o.), produced significant increase in adhesion of neutrophils and an increase in phagocytic index in carbon clearance assay. Both doses of Aegle marmelos prevented the mortality induced by bovine Pasteurella multocida in mice. Moreover, all treated groups demonstrated significant elevation in circulating antibody titre in the indirect haemagglunation test. From the above results, it can be concluded that methanol extract of Aegle marmelos possess immunomodulatory potential by stimulating cellular and humoral immune mechanisms. However, low dose of methanol extract of Aegle marmelos was more effective for augmenting cellular immunity, whereas, high dose was more inclined towards humoral immunity. 相似文献

A new therapeutic approach called Endotherapia (GEMSP) for the treatment of Multiple Sclerosis (MS) is suggested. Endotherapia is the result of an immunopathological strategy addressing chronic incurable diseases with a multifactorial etiology. This approach combines a biomedical evaluation of circulating immunoglobulins directed against specific self-antigens and self-antigens modified by free radicals. GEMSP is a "tailor-made" combination of small molecules (fatty acids, antioxidants, radical scavengers, amino acids) linked to a non-immunogenic linear chain of poly-L.lysine (PLL). Each individual linkage or PLL derivative offers great advantages, such as an increase in the half-life of the active small molecules. GEMSP inhibits brain leukocyte infiltration and abolishes episodes of experimental autoimmune encephalomyelitis. In a clinical trial with 102 MS patients treated with GEMSP Endotherapia, 28% of them showed a worsening of their state; 20% showed a decrease in the progression of the disease; 17% showed disease stabilization; and 35% showed a reversal of the evolution of disease; i.e., an improvement in their disease state. In 72% of the cases, a positive evolution of the state of the MS patients treated with Endotherapia was observed (a decrease or stabilization of disease evolution or an improvement). Endotherapia is very safe and no side-effects were reported for GEMSP. Moreover, GEMSP showed no toxicity either in experimental animals or in humans. It seems that Endotherapia is a promising therapy for MS, with no side-effects, which should be considered in the management of long-term pathologies. 相似文献
