Abstract
In this narrative review, we analyze pre-registration and post-marketing data concerning hepatotoxicity of all disease-modifying therapies (DMTs) available for the treatment of relapsing-remitting multiple sclerosis, including beta interferon, glatiramer acetate, fingolimod, teriflunomide, dimethyl fumarate, cladribine, natalizumab, alemtuzumab, and ocrelizumab. We review the proposed causal mechanisms described in the literature and we also address issues like use of DMTs in patients with viral hepatitis or liver cirrhosis. Most data emerged in the post-marketing phase by reports to national pharmacovigilance agencies and published case reports or case series. Serious liver adverse events are rare, but exact incidence is largely unknown, as are predictive factors. Unfortunately, none of the DMTs currently available for the treatment of multiple sclerosis is free of potential hepatic toxic effects. Cases of acute liver failure have been reported for beta-interferon, fingolimod, natalizumab, alemtuzumab, and ocrelizumab by different mechanisms (idiosyncratic reaction, autoimmune hepatitis, or viral reactivation). Patients with multiple sclerosis should be informed about possible hepatic side effects of their treatment. Most cases of liver injury are idiosyncratic and unpredictable. The specific monitoring schedule for each DMT has been reviewed and the clinician should be ready to recognize clinical symptoms suggestive for liver injury. Not all DMTs are indicated in cirrhotic patients. For some DMTs, screening for hepatitis B virus and hepatitis C virus is required before starting treatment and a monitoring or antiviral prophylaxis schedule has been established. Beta interferon, glatiramer acetate, natalizumab, and alemtuzumab are relatively contraindicated in autoimmune hepatitis due to the risk of disease exacerbation.

Abstract
OBJECTIVE To determine the time to efficacy onset of glatiramer acetate (GA) 40 mg/mL 3-times-weekly formulation (GA40). METHODS This post hoc analysis of data from the 1-year, double-blind, placebo-controlled phase of the Glatiramer Acetate Low-Frequency Administration study (NCT01067521) of GA40 in patients with relapsing-remitting MS (RRMS) sought to determine the timing of efficacy onset using a novel data-censoring approach. RESULTS Compared with placebo-treated patients, those receiving GA40 exhibited a >30% reduction in the accumulated annualized relapse rate (ARR) within 2 months of initiating treatment and generally sustained this treatment difference during the 1-year study. Similarly, the proportion of GA40-treated patients who remained relapse-free was distinctly greater by month 2 and continued to increase up to a 10.8% difference at the end of the study. In addition, GA40 treatment was associated with a significant reduction in the number of gadolinium-enhancing T1 lesions and new/enlarging T2 lesions by month 6, with full treatment effect observed after 1 year. CONCLUSIONS GA40 contributes to efficacy within 2 months of the start of treatment in patients with RRMS. These results are consistent with the observed time to efficacy onset for patients treated with GA 20 mg/mL daily in previous randomized, placebo-controlled clinical trials. CLASSIFICATION OF EVIDENCE This study provides Class II evidence that for patients with RRMS, a 3-times-weekly formulation of GA 40 mg/mL leads to a >30% reduction in the ARR within 2 months.

Abstract
Background:The ability to predict conversion to multiple sclerosis (MS) accurately when assessing a patient with a clinically isolated syndrome (CIS) is of paramount importance.Magnetic resonance imaging (MRI) is the best paraclinical tool currently available; however the significance of a history of an event suggestive of demyelination prior to CIS presentation has not been evaluated.Methods:Aretrospective chart review of all optic neuritis cases presenting as CIS to a single neuro-ophthalmologist in London, Ontario between 1990 to 1998 was performed. Data were collected regarding demographics, past medical history, history of present illness, and family history. Conversion to MS was determined by the McDonald criteria after ten years of follow-up. Bayesian statistics and logistic regression were used to determine the best predictors of conversion to MS from CIS.Results:One hundred and sixteen optic neuritis subjects were included in the analysis. After ten years, 42.2% had converted to MS. The best predictor of future conversion remained at least one brain lesion, disseminated in space, on MRI (sensitivity 0.90, specificity 0.75). However, if the subject additionally had a history suggestive of a demyelinating event in the past that had not been confirmed clinically, the specificity increased to 0.96. These two traits taken together had an odds ratio of 27.8 for conversion to MS in the next ten years (p<0.001).Conclusions:A history of an event suggestive of demyelination prior to presenting with optic neuritis as CIS increases the ability of the clinician to predict conversion to MS in the next ten years.

Abstract
Glatiramer acetate and interferon-beta are approved first-line disease-modifying treatments (DMTs) for multiple sclerosis (MS). DMTs can be associated with cutaneous adverse events, which may influence treatment adherence and patient quality of life. In this systematic review, we aimed to provide an overview of the clinical spectrum and the incidence of skin reactions associated with DMTs. A systematic literature search was performed up to May 2011 in Medline, Embase, and Cochrane databases without applying restrictions in study design, language, or publishing date. Eligible for inclusion were articles describing any skin reaction related to DMTs in MS patients. Selection of articles and data extraction were performed by two authors independently. One hundred and six articles were included, of which 41 (39%) were randomized controlled trials or cohort studies reporting incidences of mainly local injection-site reactions. A large number of patients had experienced some form of localized injection-site reaction: up to 90% for those using subcutaneous formulations and up to 33% for those using an intramuscular formulation. Sixty-five case-reports involving 106 MS patients described a wide spectrum of cutaneous adverse events, the most frequently reported being lipoatrophy, cutaneous necrosis and ulcers, and various immune-mediated inflammatory skin diseases. DMTs for MS are frequently associated with local injection-site reactions and a wide spectrum of generalized cutaneous adverse events, in particular, the subcutaneous formulations. Although some of the skin reactions may be severe and persistent, most of them are mild and do not require cessation of DMT.

Abstract
Reviews of therapeutic drugs usually focus on the highly selected and closely monitored patient populations from randomized controlled trials. The objective of this study was to review systematically the tolerability and adherence of multiple sclerosis disease-modifying therapies, using data from both randomized controlled trials and observational settings. Relevant literature was identified using predefined search terms, and adverse event and study discontinuation data were extracted and categorized according to study type (randomized controlled trial or observational) and study duration. A total of 151 papers were selected for analysis; 33% were classified as randomized controlled trials and 62% as observational studies. Most of the papers concerned interferon preparations and glatiramer acetate; the limited available information on mitoxantrone and natalizumab precluded extensive examination of these. The most common adverse events were flu-like symptoms (interferon therapies only) and injection-site reactions. Mean discontinuation rates ranged from 16% to 27%. There were no marked differences in tolerability or adherence data from randomized controlled trials and observational studies, but the incidence of adverse events remained high in lengthy studies and discontinuations accumulated with time. The present systematic review of randomized clinical trial and observational data highlights the tolerability and adherence issues associated with commonly used first-line multiple sclerosis treatments.

Abstract
Since the mid-1990s several disease-modifying drugs (DMDs), such as β-interferons and glatiramer acetate, have become available to treat patients with relapse-remitting multiple sclerosis (MS). These therapies have known short- and medium-term benefit in reducing relapses, disability progression, and accrual of new inflammatory lesions. However, the short duration of the randomized pivotal MS trials have provided little to no information about benefit from such treatment over periods of extended (>5 years) use. Whether DMDs may significantly alter the development of long-term disability remains uncertain, thus it remains challenging how to best approach the issue of long-term benefits from these treatments.

Abstract
BACKGROUND This is an updated Cochrane review of the previous version published (Cochrane Database of Systematic Reviews 2004 , Issue 1 . Art. No.: CD004678. DOI: 10.1002/14651858.CD004678)Previous studies have shown that glatiramer acetate (Copaxone (R)), a synthetic amino acid polymer is effective in experimental allergic encephalomyelitis (EAE), and improve the outcome of patients with multiple sclerosis (MS). OBJECTIVES To verify the clinical efficacy of glatiramer acetate in the treatment of MS patients with relapsing remitting (RR) and progressive (P) course. SEARCH STRATEGY We searched the Cochrane MS Group Trials Register (26 March 2009), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 1, 2009), MEDLINE (PubMed) (January 1966 to 26 March 2009), EMBASE (January 1988 to 26 March 2009) and hand searching of symposia reports (1990-2009). SELECTION CRITERIA All randomised controlled trials (RCTs) comparing glatiramer acetate and placebo in patients with definite MS, whatever the administration schedule and disease course, were eligible for this review. DATA COLLECTION AND ANALYSIS Both patients with RR and P MS were analysed. Study protocols were comparable across trials. No major flaws were found in methodological quality. However, efficacy of blinding should be balanced against side effects, including injection-site reactions. MAIN RESULTS Among 409 retrieved references, we identified 16 RCTs; six of them, published between 1987 and 2007, met the selection criteria and were included in this review. Five hundred and forty RR patients and 1049 PMS contributed to the analysis. In RR MS, a decrease in the mean EDSS score (-0.33 and -0.45), was found respectively at 2 years and 35 months without any significant effect on sustained disease progression. The reduction of mean number of relapse was evident at 1 year (-0.35 ) 2 years (-0.51 ) and 35 months (-0.64), but significant studies ' heterogeneity was found. The number of hospitalisations and steroid courses were significantly reduced. No benefit was shown in P MS patients. No major toxicity was found. The most common systemic adverse event was a transient and self-limiting patterned reaction of flushing, chest tightness, sweating, palpitations, anxiety. Local injection-site reactions were observed in up to a half of patients treated with glatiramer acetate, thus making a blind assessment of outcomes questionable. AUTHORS' CONCLUSIONS Glatiramer acetate did show a partial efficacy in RR MS in term of relapse -related clinical outcomes, without any significant effect on clinical progression of disease measured as sustained disability. The drug is not effective in progressive MS patients.

Abstract
A consequence of the long-term nature of progression in multiple sclerosis is that treatment needs to be provided over the long term. Gathering evidence for long term clinical efficacy, safety and patient acceptance of immunomodulatory therapies is thus a critically important issue. However, pivotal trials, which generally last no more than two years, cannot address this issue. Glatiramer acetate is the only immunomodulatory treatment for which prospective data is available covering a treatment period of over a decade. In the long-term extension of the pivotal trial of glatiramer acetate, 108 patients have been followed for a mean treatment duration of 10.1 years. At the end of the treatment period, patients were experiencing a relapse only once every five years and 92% remained ambulatory throughout. Similar findings have been made in observational studies in the long-term follow-up of patients with relapsing remitting multiple sclerosis treated with glatiramer acetate under a compassionate use programme in France and in a patient registry in Argentina. Such data strongly suggest that a reduced risk of relapse represents a real long-term treatment effect. The cumulative evidence for the long-term clinical efficacy of glatiramer acetate is consistent with its dual mechanism of action, reassures the physician that glatiramer acetate can really help improve patient care over the long term, and may contribute to a more positive view of prognosis for patients with multiple sclerosis.
