BACKGROUND: New daily persistent headache (NDPH) is an often treatment-refractory primary headache disorder with a lack of evidence base for treatment.
METHODS: We performed an observational study using prospectively collected data in consecutive patients with NDPH, chronic migraine with daily headache (daily-CM) and without daily headache (non-daily-CM). Patients were treated with two cycles of OnabotulinumtoxinA. Propensity score matching was used to control for imbalances between the groups. The primary outcome measure was the proportion who experienced a ≥ 30% improvement in monthly moderate-to-severe headache days at 24 weeks.
RESULTS: We included 58 patients with NDPH, 148 with daily-CM, and 84 with non-daily-CM. In NDPH, 34.5% of patients experienced a ≥ 30% improvement in monthly moderate-to-severe headache days, compared to 43.2% in daily-CM and 51.2% in non-daily CM. In NDPH, 6.9% experienced an improvement in monthly headache days, 27.6% an improvement in headache severity, 25.9% a ≥ 6 point improvement in HIT-6 score, and 59% a patient reported improvement. There was no significant difference in response rates between the three groups. Adverse event rates were similar in all groups and there were no serious adverse events.
CONCLUSION: OnabotulinumtoxinA is effective in approximately 1/3 patients with NDPH and has a favourable safety profile.
