Objective: To investigate the patient satisfaction with medications commonly used for migraine therapy in patients seen in headache clinic in China with emphasis on the evaluation of Chinese patent medicine (CPM) in relieving acute migraine attack., Methods: Patients admitted at headache clinics in the neurological departments of four hospitals during April to October 2011 were enrolled in the investigation. The questionnaire was designed based on the validation of a diagnostic questionnaire for a population-based survey in China in 2009., Results: Among 219 eligible patients, 58% had used CPM at the acute attack of migraine while the guideline-recommended treatments were seldom used. However, patients using CPMs were less satisfied than those using Western Medicines (WMs) in either single medication groups or mixed medication groups (P < 0.05)., Conclusion: Fifty-eight percent of the eligible respondents in Guangdong and Guangxi Province had used CPM at the acute attack of migraine, but based on our data, the effect of CPM on treating migraine attack was poor with low satisfaction compared with WMs. However, many factors may bias or explain our findings. This suggests the need for accelerated research in understanding patient choice, treatment availability, and use of medications., (Wiley Periodicals, Inc.)

Objectives: The objective of this study was to observe the efficacy, safety, and side effects of a combination of flunarizine plus topiramate compared with either flunarizine and or toparamate alone for migraine prophylaxis., Methods: Out of 150 patients with migraine recruited into the study and randomly assigned to one of three conditions, 126 completed the trial in their group: flunarizine (39), topiramate (44), and flunarizine plus topiramate (43). Patient information was assessed at enrollment and at follow-up visits at the end of months 1-3, 6, 9, and 12. The primary measure of efficacy reduction in mean monthly migraine frequency of at least 50% as compared with baseline. Secondary efficacy parameters included reduction in mean monthly migraine days and severity of headache. Side effects were compared in the three groups by recording adverse reactions and weight changes., Results: The proportion whose monthly headache frequency decreased more than 50% was 66.7% (26/39) in the flunarizine group, 72.7% (32/44) in the topiramate group and 76.7% (33/43) in the combination group, respectively (P=0.593). The mean monthly days and severity of headache in the three groups also declined and was more significant in the flunarizine plus topiramate group than in the flunarizine group and the topiramate group (P<0.05). In the flunarizine group, the average weight change was 0.6kg. Topiramate was associated with a mean weight loss was of -0.9kg in the topiramate group and -0.2kg in the flunarizine plus topiramate group., Conclusion: Flunarizine, topiramate, and the combination of flunarizine with topiramate are all effective and have good tolerability in migraine prophylaxis. Adding topiramate to flunarizine may reduce the latter's impact on body weight., (Wiley Periodicals, Inc.)

Objective: Nearly half of Operation Enduring Freedom/Operation Iraqi Freedom veterans experience continued pain post-deployment. Several investigations report analgesic effects of allopregnanolone and other neurosteroids in animal models, but few data are currently available focusing on neurosteroids in clinical populations. Allopregnanolone positively modulates GABA(A) receptors and demonstrates pronounced analgesic and anxiolytic effects in rodents, yet studies examining the relationship between pain and allopregnanolone in humans are limited. We thus hypothesized that endogenous allopregnanolone and other neurosteroid levels may be negatively correlated with self-reported pain symptoms in humans., Design: We determined serum neurosteroid levels by gas chromatography/mass spectrometry (allopregnanolone, pregnenolone) or radioimmunoassay (dehydroepiandrosterone [DHEA], progesterone, DHEA sulfate [DHEAS]) in 90 male veterans who served in the U.S. military after September 11, 2001. Self-reported pain symptoms were assessed in four areas (low back pain, chest pain, muscle soreness, headache). Stepwise linear regression analyses were conducted to investigate the relationship between pain assessments and neurosteroids, with the inclusion of smoking, alcohol use, age, and history of traumatic brain injury as covariates., Setting: Durham VA Medical Center., Results: Allopregnanolone levels were inversely associated with low back pain (P=0.044) and chest pain (P=0.013), and DHEA levels were inversely associated with muscle soreness (P=0.024). DHEAS levels were positively associated with chest pain (P=0.001). Additionally, there was a positive association between traumatic brain injury and muscle soreness (P=0.002)., Conclusions: Neurosteroids may be relevant to the pathophysiology of self-reported pain symptoms in this veteran cohort, and could represent future pharmacological targets for pain disorders., (Wiley Periodicals, Inc.)
