Selection of patients with increased responsiveness to botulinum toxin
View Patent ↗Botulinum toxin has been shown to be useful for the treatment of pain when administered for cervical dystonia. Given efficacy for pain relief in regional dystonia, further expanded applications have included myofascial pain, muscle tension headaches, and other forms of headache syndromes. The application in headache practice has expanded to migraine as well as certain secondary headache syndromes. Although multiple case reports involving the use of botulinum toxin have shown promise in its utility for the treatment of primary pain syndromes, to date, controlled trials have failed to consistently and more definitively prove utility. Described herein is a method for selection of patients with headache syndromes more likely to respond to botulinum administration. The method involves identifying coincident diseases and signs within the patient's medical history, and selecting such patients for induction into clinical studies for pain or preferential primary treatment of pain using a botulinum based pharmaceutical.
1. A method comprising the steps of:
(a) identifying a subject with a pain syndrome and a medical history of one or more atopic diseases;
(b) selecting a subject of step (a) for the treatment of said pain syndrome with a botulinum toxin; and
(c) administering a composition comprising a botulinum toxin to said subject, thereby treating said pain syndrome,
wherein said identification and selection step is made prior to administering botulinum toxin and wherein the pain syndrome is any one or more of the pain syndromes selected from the group consisting of: post-traumatic headaches, cluster headaches, fibromyalgia, cervical radiculopathy, and whiplash.
2. The method of claim 1 wherein said atopic disease is selected from the group consisting of: recurrent hayfever, recurrent eczema and asthma.
3. The method of claim 1 wherein the botulinum toxin is any form of immunotypes A, B, C, D, E, F, or G.
4. A method comprising the steps of:
(a) identifying a subject with a pain syndrome that exhibits geste antagoniste phenomenon;
(b) selecting a subject of step (a) for the treatment of said pain syndrome with a botulinum toxin; and
(c) administering a composition comprising a botulinum toxin to said subject, thereby treating said pain syndrome,
wherein said identification and selection step is made prior to administering botulinum toxin and wherein the pain syndrome is any one or more of the pain syndromes selected from the group consisting of: post-traumatic headaches, cluster headaches, fibromyalgia, cervical radiculopathy, and whiplash.
5. The method of claim 4 wherein the botulinum toxin is any form of immunotypes A, B, C, D, F, F, or G.
6. The method of claim 1 wherein said composition is administered to the head or neck.
7. The method of claim 4 wherein said composition is administered to the head or neck.
8. A method comprising the steps of:
(a) identifying a subject with a pain syndrome and an atopic predisposition or a presence of atopic disease;
(b) selecting a subject of step (a) for the treatment of said pain syndrome with a botulinum toxin; and
(c) administering a composition comprising a botulinum toxin to said subject, thereby treating said pain syndrome,
wherein said identification and selection step is made prior to administering botulinum toxin and wherein the pain syndrome is any one or more of the pain syndromes selected from the group consisting of: post-traumatic headaches, cluster headaches, fibromyalgia, cervical radiculopathy, and whiplash.
9. The method of claim 8 wherein the subject identified in step (a) has atopic predisposition.
10. The method of claim 8 wherein the subject identified in step (a) has the presence of atopic disease.
