Multiple sclerosis is a leading cause of disability in young adults. Mitoxantrone has recently been shown to be effective in ameliorating multiple sclerosis activity and reducing the relapse rate. This study aimed to assess the efficacy of mitoxantrone on disease activity and decreasing relapse rate in patients with multiple sclerosis in Iran.
This was a clinical trial on patients who received intravenous mitoxantrone, 12 mg/m2 every 3 months. The study was performed at Isfahan Multiple Sclerosis Clinics, affiliated to Isfahan University of Medical Sciences. This clinical trial was conducted from October 2003 through April 2005. One hundred and forty-seven patients with worsening relapsing-remitting and secondary progressive multiple sclerosis received mitoxantrone, 12 mg/m(2) every 3 months. Clinical assessment was made every 3 months for one year.
Of the 147 patients, 129 (93 females and 36 males) could successfully complete the course of our study. A significant therapeutic effect (P < 0.0001) was detected for the attack rate before and after treatment. The Mean attack rate 12 months before treatment was 1.10 (SD = 0.95), which reduced to 0.09 (SD = 0.29) during treatment. The Mean expanded disability status scale at the beginning of the treatment was 4.32, which declined to 3.62 (P < 0.0001) after one year.
Mitoxantrone was generally well tolerated and reduced progression of disability and clinical exacerbation in our patients. Physicians must be careful about the complications of mitoxantrone especially cardiotoxicity.

    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: MS is an immune-mediated chronic disorder of the central nervous system (CNS) characterized by multiple areas of inflammation and demyelination. MS is among the commonest causes of neurological disability in young people. Steroids, interferon and other drugs have been used to treat specific symptoms. This review determined that MX, widely used for treatment of breast cancer and leukaemia, was moderately effective in the short-term treatment of MS. The most frequent side-effects are transitory amenorrhoea, nausea and vomiting, alopecia, urinary tract infections and transitory leucopenia. However, caution must be exercised when interpreting these results, because of the heterogeneous quality and characteristics of the included trials, which are different in terms of treatment schedule and type of enrolled patients. Moreover, there are little information on the long term effects of MX, especially as regards the risk of cardiotoxicity and therapy-related acute leukemias, which is increasingly reported in the literature.
