Program Abstracts PO349Sustained efficacy of botulinum toxin type-A (BTXA)on migraine-related disability over 3 treatment cyclesin a community-based settingTurner IM, Harding TM, DeVito DA and Lio RThe Center for Headache Care and Research, IslandNeurological Associates, PC, Plainview, NY, USA Objectives: To retrospectively assess the effect of botulinum toxintype-A (BTXA) on migraine disability over 3 consecutive treatmentcycles scheduled at 3-month intervals in a community-based head-ache subspecialty practice.
Background: Prior studies using BTXA have shown a decrease inmigraine-related disability, headache days and acute medicationusage. These findings have the potential to result in a substantialreduction in disease burden for patients, employers, insurers andsociety if this is maintained over serial treatment cycles.
Methods: Forty consecutive patients treated for either chronicmigraine (15 or more headache days per month) or high frequencymigraine (8–14 days per month) who underwent 3 consecutive coursesof BTXA treatment at 3-month intervals were retrospectively reviewed.
The primary endpoint was a reduction in Migraine Disability Assess-ment Scores (MIDAS). Secondary endpoints included a decrease inheadache days and as well as a decrease in acute medication use.
Results: Average MIDAS scores decreased from a baseline of 62.8 to29.2 (treatment 1), 31.1 (treatment 2) and 24.8 (treatment 3) over 3consecutive cycles. Headache days decreased from a baseline of aver-age of 20.7 days per month to 11.6 (treatment 1), 9.8 (treatment 2) and 9.5 (treatment 3) days per month respectively. Monthly acutemedication doses decreased from a baseline average of 51.5 to 27.85(treatment 1), 24.25 (treatment 2) and 21.4 (treatment 3) for the 3cycles of treatment.
Methods: Sixty patients, 18 years of age and older, non-pregnant, Conclusions: In our retrospective analysis of 40 consecutive patients who met International Headache Society criteria for migraine and there was a sustained reduction in migraine-related disability, head- tension-type headaches were randomly assigned to three treatment ache days and acute medication use.

In a previous study (presented at the Headache and Migraine Trust International Congress 2008), 20 consecutive refractory CDH patients treated in a headache center, all scoring "severe and disabling" on their HIT-6 questionnaire despite maximal oral prophylactic medication, were properly fitted with an NTI device and wore nightly for 9 months. Within two months of nightly NTI use, and then persisting for the nine months of observation, half of the subjects had a significant improvement, while 25% reported that chronic headache no longer had any impact on their lives.
DEPAKOTE (valproic acid) is FDA approved for prophylactic treatment of migraine.
The adverse events with Valproic acid treatment include: weight gain, fatigue, alopecia, hirsutism, tremor, and liver function abnormalities. Most of the side effects are dose related and worsen with higher doses.
Methods: 60 patients, 18 years of age and older, non-pregnant, met IHS criteria for migraine and tension-type headaches;
randomly assigned to three treatment groups, 20 pts per arm: Valproic acid alone, NTI splint alone, and combination of NTI and Valproic Acid. Valproic Acid dosage in the treatment arms was 200 mg bid. Clinical follow-up was performed for 8 weeks at weekly intervals. The patients reported headache on a visual analog scale before treatment and also after every week in their treatment period. Side effects were reported. Data collected and compared between the groups using the Mann-Whitney and Wilcoxon test.
Results: There was a statically
significantly superior improvement for the combination of Valproic Acid and NTI compared to either of the two individual treatments, with no statistical difference in treatment efficacy between the Valproic Depakote + NTI
acid and NTI treatment arms. There were no systemic adverse side-effects with the NTI, while side effects were present for patients treated with Valproic Acid but did not worsen when combined with the NTI.
Conclusion: The known therapeutic
gain of Valproic Acid can be increased without risking the escalation of the known side effects of increasing dosage, by combining Valproic Acid with the proper use of an NTI device.
