There is no consensus on whether patients turning to private tertiary centers are different from those seen in public nonpaying services. However, since it is directly related to economic status and public services may render free specific medications as well as official dispensation of work, it may be argued that patients have less headache impact, and suboptimal care is delivered in these instances. As for the studied private centers as well as for the few public excellence centers, care provided is usually varied, includes a combination of drugs, and prevention is commonly used.
Proton MRS may be useful as an imaging marker for PTH following mild injury. Future studies should contrast PTH following mild vs severe trauma, as well as PTH with other forms of headache, to clarify if the findings are specific of the disease, may be correlated with disease severity, or if they are unspecific headache markers.
Withdrawing overused medications, starting prevention, and motivating patients may have helped the high adherence rates and decreasing headache frequency. Additionally, real-world patient studies are scarce and may be useful to guide clinicians struggling to help their daily headache patients. Open studies do not allow definitive conclusions and controlled studies with this subset of patients are necessary.
A sizeable proportion of migraineurs in need of preventive therapy do not significantly benefit from monotherapy. The objective of the study is to conduct a randomized controlled trial testing whether combination therapy of topiramate and nortriptyline is useful in patients who had less than 50% decrease in headache frequency with the use of the single agents. Patients with episodic migraine were enrolled if they had less than 50% reduction in headache frequency after 8 weeks of using topiramate (TPM) (100 mg/day) or nortriptyline (NTP) (30 mg/day). They were randomized (blinded fashion) to have placebo added to their regimen, or to receive the second medication (combination therapy). Primary endpoint was decrease in number of headache days at 6 weeks, relative to baseline, comparing both groups. Secondary endpoint was proportion of patients with at least 50% reduction in headache frequency at 6 weeks relative to baseline. A total of 38 patients were randomized to receive combination therapy, while 30 continued on monotherapy (with placebo) (six drop outs in the combination group and three for each single drug group). For the primary endpoint, mean and standard deviation (SD) of reduction in headache frequency were 4.6 (1.9) for those in polytherapy, relative to 3.5 (2.3) for those in monotherapy. Differences were significant (p < 0.05]. Similarly, 78.3% of patients randomized to receive polytherapy had at least 50% headache reduction, as compared to 37% in monotherapy (p < 0.04). Finally we conclude that combination therapy (of TPM and NTP) is effective in patients with incomplete benefit using these agents in monotherapy.
Our findings suggest that decreased values of ABI are more common in migraineurs than in controls. Although causality was not assessed by us, the relationship is of importance per se. Doctors should measure the ABI in individuals with migraine as an easy way to screen for cardiovascular risk.
Medication-overuse headache (MOH) is a challenging neurological disease, which brings frustration for sufferers and treating physicians. The patient’s lack of adherence and limited treatment evidence are frequent. The aim of this study was to compare the outcome and treatment strategies between consecutive MOH patients with daily and near-daily headache from a tertiary center. Methods: Every consecutive patient seen between January and December 2014 with the diagnosis of MOH was included. Psychiatric comorbidities, inability to inform baseline headache frequency, current or previous two-month use of preventive medications, and refusal to sign informed consent were exclusion criteria. The patients were evaluated in thorough initial consultations and divided in two groups based on their baseline headache frequency. The diagnosis and treatment strategies were clearly explained. The filling out of a detailed headache diary was requested from all patients. Endpoints compared headache frequency and adherence after two, four, and eight months between the two study groups. Results: One-hundred sixty-eight patients (31 male, 137 female) met the inclusion criteria. Nineteen patients (11.3%) were excluded. All patients had migraine or chronic migraine as primary headaches. Eighty had daily (DH), and 69 near-daily headache (NDH), at baseline consultation. Mean baseline frequency was 24.8 headache days/month (18.9 days/month for the near-daily group), average headache history was 20.6 years and mean time with >15 headache days/month was 4.8 years. Outpatient withdrawal, starting prevention, and enforcing the correct use of rescue therapy was carried out with all patients. After two months, 88% of the DH and 71% of the NDH groups adhered to treatment (p = 0.0002). The HF decreased to 12 and 9 headache days/month, respectively in DH and NDH groups (p > 0.05, non-significant) (Intention-to-treat (ITT) 14 DH; 12 NDH; p > 0.05). After four and eight months, 86.3% and 83.7% of the DH patients, and 59.4% and 55% of the NDH patients were still under treatment (p = 0.0003 and p = 0.0001). The HF decreased, respectively, to nine and nine headache days/month in the DH patients compared to 6 and 7 headache days/month in the NDH group (p > 0.05) (ITT, 12; 12; DH; 10; 11; NDH; p > 0.05). Conclusions: Although open studies provide limited conclusions, withdrawing overused medications and starting prevention may have helped the favorable outcomes. However, daily headache patients had a significantly higher adherence and lower relapse rates than near-daily headache patients, despite a considerable reduced headache frequency in both groups. Additionally, real-world patient studies are scarce and the comparison between these two subsets of patients may be useful to guide clinicians in approaching their patients. Controlled studies are necessary to confirm these observations.
-Background:Migraine is a prevalent neurological disorder. Although prevention is the mainstream treatment, some patients are refractory to standard therapies. Aim: To evaluate the use of quetiapine (QTP) in the preventive treatment of refractory migraine, defined as previous unresponsiveness to the combination atenolol + nortriptyline + flunarizine. Method: Thirty-four consecutive patients (30 women and 4 men) with migraine (ICHD-II) and headache attacks on less than 15 days per month not overusing symptomatic medications were studied. The main inclusion criterion was the lack of response (<50% reduction in attack frequency) after ten weeks to the combination of atenolol (60 mg/day) + nortriptyline (25 mg/day) + flunarizine (3 mg/day). The patients started on QTP as the sole treatment in a single daily dose of 25 mg, titrated to 75 mg. After ten weeks, headache frequency, consumption of rescue medications and adverse events were analyzed. Results: Twenty nine patients completed the study. Among completers, 22 (75.9%; 64.7% of the intention-to-treat population) presented >50% headache reduction. The mean frequency of migraine days decreased from 10.2 to 6.2 and the average consumption of rescue medications decreased from 2.3 to 1.2 days/week. Adverse events were reported by 9 (31%) patients. Conclusion: Although limited by the open design, this study provides a pilot data to support the use of quetiapine in preventive treatment of refractory migraine.Key worDs: migraine, quetiapine, preventive treatment, refractory.Quetiapina para a prevenção da migrânea refratária à combinação de atenolol + nortriptilina + flunarizina: estudo piloto aberto Resumo -Introdução: A migrânea é uma doença neurológica prevalente. embora a prevenção seja o esteio principal do tratamento, alguns pacientes são refratários aos tratamentos tradicionais. Objetivo: Avaliar o uso da quetiapina (QTP) no tratamento preventivo da migrânea refratária definida como ausência de resposta ao uso prévio da combinação de atenolol com nortriptilina e flunarizina. Método: Trinta e quatro pacientes consecutivos (30 mulheres e 4 homens) com migrânea (CIC-II) e crises de cefaléia em menos de 15 dias/mês sem uso excessivo de sintomáticos foram estudados. o critério de inclusão principal foi a não obtenção na redução da frequência de cefaléia >50% após 10 semanas de uso da combinação de atenolol (60 mg/dia) + nortriptilina (25 mg/dia) + flunarizina (3 mg/dia). os pacientes iniciaram a QTP como tratamento único na dose de 25 mg à noite e aumentaram-na até 75 mg. Após 10 semanas de uso, a frequência da cefaléia, o consumo de sintomáticos e os efeitos colaterais foram avaliados. Resultados: Vinte e nove pacientes completaram o estudo. entre os que completaram, 22 (75.9%; 64.7% dos pacientes que foram incluídos) obtiveram redução da frequência >50%. A frequência média de dias com migrânea por mês decresceu de 10,2 para 6,2. o consumo médio de sintomáticos caiu de 2,3 para 1,2 dias/semana. efeitos colaterais foram relatados por 9 (31%) pacientes.
