Most patients with multiple sclerosis (MS) aged >60 who discontinued disease modifying therapy (DMT) remained off treatment, a recent study found. Among the outcomes, only the European Quality of Life 5 Dimensions (EQ-5D) index demonstrated significant differences over time, with continuers having lower quality of life scores compared to discontinuers before discontinuation (DBD). Researchers conducted a retrospective, observational study in which they identified patients from MS clinics aged ≥60 years who had been on DMT ≥2 years. They compared outcome evolution over time among treatment groups (continuers, DBD), and discontinuers after discontinuation [DAD]), by creating separate mixed-effects linear regression models that included an interaction term between time from age 60 and treatment group to study outcome trajectories. They found:
- 178 of 600 patients discontinued DMT, and 89.3% (n=159) of those who discontinued remained off DMT.
- Only the EQ-5D mixed-effects linear regression model with the interaction term was statistically significant.
- The slope relating time to EQ-5D was significantly different when comparing continuers to DBD.
- The slopes were not significantly different when comparing continuers to DAD, or when comparing the before and after discontinuation slopes among the discontinuers.
