Objective: To measure the effects of disease-modifying drugs (DMDs) on the development of cortical lesions (CL) and cortical atrophy in patients with relapsing–remitting multiple sclerosis (RRMS). Methods: RRMS patients ( n = 165) were randomized to subcutaneous (sc) interferon (IFN) beta-1a (44 mcg three times weekly), intramuscular (im) IFN beta-1a (30 mcg weekly) or glatiramer acetate (GA; 20 mg daily). The reference population comprised 50 untreated patients. Clinical and MRI examinations were performed at baseline, 12 months and 24 months. Results: One hundred and forty-one treated patients completed the study. After 12 months, 37/50 (74%) of untreated patients developed ≥1 new CL (mean 1.6), compared with 30/47 (64%) of im IFN beta-1a-treated patients (mean 1.2, p = 0.021), 24/48 (50%) of GA-treated patients (mean 0.8, p = 0.001) and 12/46 (26%) of sc IFN beta-1a-treated patients (mean 0.4, p < 0.001). After 24 months, ≥1 new CL was observed in 41/50 (82%) of untreated (mean 3.0), 34/47 (72%) of im IFN beta-1a-treated (mean 1.6, p < 0.001), 30/48 (62%) of GA-treated (mean 1.3, p < 0.001) and 24/46 (52%) of sc IFN beta-1a-treated patients (mean 0.8, p < 0.001). Mean grey matter fraction decrease in DMD-treated patients at 24 months ranged from 0.7 to 0.8 versus 1.0 in untreated patients ( p = 0.023). Conclusions: Disease-modifying drugs significantly decreased new CL development and cortical atrophy progression compared with untreated patients, with faster and more pronounced effects seen with sc IFN beta-1a than with im IFN beta-1a or GA.

Cortical lesions (CLs) and atrophy are pivotal in multiple sclerosis (MS) pathology. This study determined the effect of disease modifying drugs (DMDs) on CL development and cortical atrophy progression in patients with relapsing-remitting MS (RRMS) over 48 months. Patients (n=165) were randomized to sc IFNβ-1a 44 μg, im IFNβ-1a 30 μg, or glatiramer acetate 20 mg. The reference population comprised 50 DMD-untreated patients with RRMS. After 24 months, 43 of the untreated patients switched to DMDs. The four groups of patients were followed up for an additional 24 months. At 48 months the mean standard deviation number of new CLs was significantly lower in patients treated with sc IFNβ-1a (1.4 ± 1.0, range 0–5) compared with im IFNβ-1a (2.3 ± 1.3, range 0–6,P=0.004) and glatiramer acetate (2.2 ± 1.5, range 0–7,P=0.03). Significant reductions in CL accumulation and new white matter and gadolinium-enhancing lesions were also observed in the 43 patients who switched to DMDs after 24 months, compared with the 24 months of no treatment. Concluding, this study confirms that DMDs significantly reduce CL development and cortical atrophy progression compared with no treatment.

For patients with Relapsing Remitting Multiple Scierosis Beta Interfaerons and Glatiramer Acetate were the first to be licensed for treatment. This review deals with one major question: when to initiate therapy? Through exploring the unique characteristics of the disease and treatement we suggest an approach that should be helpful in the process of decision-making.

Abstract The emergence of partially effective disease-modifying drugs for patients with relapsing remitting multiple sclerosis (RR-MS) has raised important questions. Which patients with RR-MS should be started on disease-modifying drugs? Can some patients be observed without treatment? Treatment decisions are difficult in part because currently available drugs must be administered by injections, and the drugs are expensive. Emerging research findings support the view that most people diagnosed with RR-MS are at risk for irreversible brain tissue injury and resultant neurologic disability. Importantly, the pathologic process is active during the early stages in many RR-MS patients who appear clinically stable. These findings provide a rationale for proactively treating patients with RR-MS early in their disease course with disease-modifying drugs in order to suppress disease activity, minimize tissue injury, and prevent disability at a later stage. Evidence in support of this approach is reviewed in this report, as are practical issues related to the use of disease-modifying drugs in RR-MS patients.
