The International Panel on MS Diagnosis presents revised diagnostic criteria for multiple sclerosis (MS). The focus remains on the objective demonstration of dissemination of lesions in both time and space. Magnetic resonance imaging is integrated with clinical and other paraclinical diagnostic methods. The revised criteria facilitate the diagnosis of MS in patients with a variety of presentations, including "monosymptomatic" disease suggestive of MS, disease with a typical relapsingremitting course, and disease with insidious progression, without clear attacks and remissions. Previously used terms such as "clinically definite" and "probable MS" are no longer recommended. The outcome of a diagnostic evaluation is either MS, "possible MS" (for those at risk for MS, but for whom diagnostic evaluation is equivocal), or "not MS."
The accepted standard treatment of relapsing multiple sclerosis consists of medications for disease symptoms, including treatment for acute exacerbations. However, currently there is no therapy that alters the progression of physical disability associated with this disease. The purpose of this study was to determine whether interferon beta-1a could slow the progressive, irreversible, neurological disability of relapsing multiple sclerosis. Three hundred one patients with relapsing multiple sclerosis were randomized into a double-blinded, placebo-controlled, multicenter phase III trial of interferon beta-1a. Interferon beta-1a, 6.0 million units (30 micrograms¿, was administered by intramuscular injection weekly. The primary outcome variable was time to sustained disability progression of at least 1.0 point on the Kurtzke Expanded Disability Status Scale (EDSS). Interferon beta-1a treatment produced a significant delay in time to sustained EDSS progression (p = 0.02). The Kaplan-Meier estimate of the proportion of patients progressing by the end of 104 weeks was 34.9% in the placebo group and 21.9% in the interferon beta-1a-treated group. Patients treated with interferon beta-1a also had significantly fewer exacerbations (p = 0.03) and a significantly lower number and volume of gadolinium-enhanced brain lesions on magnetic resonance images (p-values ranging between 0.02 and 0.05). Over 2 years, the annual exacerbation rate was 0.90 in placebo-treated patients versus 0.61 in interferon beta-1a-treated patients. There were no major adverse events related to treatment. Interferon beta-1a had a significant beneficial impact in relapsing multiple sclerosis patients by reducing the accumulation of permanent physical disability, exacerbation frequency, and disease activity measured by gadolinium-enhanced lesions on brain magnetic resonance images. This treatment may alter the fundamental course of relapsing multiple sclerosis.
NAB directed against IFN-beta have in vivo biological consequences in patients with MS. The frequency with which MS patients develop NAB against IFN-beta is significantly greater with IFN-beta-1b therapy compared with IFN-beta-1a therapy. Treatment decisions in MS patients treated with IFN-beta should take into account development of NAB.
This study examined the efficacy of an 8-week telephone-administered cognitive-behavioral therapy (CBT) for the treatment of depressive symptomatology in multiple sclerosis (MS) patients. The treatment, Coping with MS (CMS), included a patient workbook designed to structure the treatment, provide visual aids, and help with homework assignments. Thirty-two patients with MS, who scored at least 15 on the Profile of Mood States Depression-Dejection scale, were randomly assigned to either the telephone CMS or to a usual-care control (UCC) condition. Depressive symptomatology decreased significantly in the CMS condition compared with the UCC condition. Furthermore, adherence to interferon beta-1a, a disease-modifying medication for the treatment of MS, was significantly better at the 4-month follow-up among patients who received CMS as compared with those in the UCC condition.
This study compared the efficacy of 3 16-week treatments for depression in 63 patients with multiple sclerosis (MS) and major depressive disorder (MDD): individual cognitive-behavioral therapy (CBT), supportive-expressive group therapy (SEG). and the antidepressant sertraline. Significant reductions were seen from pre- to posttreatment in all measures of depression. Intent-to-treat and completers analyses using the Beck Depression Inventory (BDI; A. T. Beck, C. H. Ward. M. Medelson. J. Mock, & J. Erbaugh, 1961) and MDD diagnosis found that CBT and sertraline were more effective than SEG at reducing depression. These results were largely supported by the BDI-18, which eliminates BDI items confounded with MS. However, the Hamilton Rating Scale for Depression (M. Hamilton, 1960) did not show consistent differences between treatments. Reasons for this inconsistency are discussed. These findings suggest that CBT or sertraline is more likely to be effective in treating MDD in MS compared with supportive group treatments.
These findings support previous findings that patients report increased depression after initiating therapy with IFN beta-1b. Although the source of this depression is unclear, these findings suggest that treating patient-reported depression increases adherence to treatment.
This study examined subjective patient experiences of the psychosocial consequences of multiple sclerosis (MS). Fifty patients were interviewed regarding the effects MS had on their lives and interpersonal relationships. These statements were collated and administered with a 5-point Likert scale to 94 MS patients. The responses were subjected to factor analysis. Three areas of subjective patient experience of the psychosocial consequences of MS emerged: demoralization, benefit-finding, and deteriorated relationships. Of particular interest was benefit-finding, which included a deepening of relationships, enhanced appreciation of life, and an increase in spiritual interests. Although benefit-finding was related to adaptive coping strategies such as positive reappraisal and seeking social support, it was unrelated to depression and was related to higher levels of anxiety and anger. These findings indicate that benefit-finding is a substantial and poorly understood part of the illness experience for MS patients.
These data provide support for the notion that conflict and disruption in routine are related to subsequent disease activity in MS. However, this relationship is not sufficiently robust to predict clinical exacerbations reliably in individual patients.
