Family History for Chronic Headache and Drug Overuse as a Risk Factor for Headache Chronification

Objectives.— To assess whether family history for chronic headache (CH) and drug overuse could represent a risk factor for headache chronification. Background.— Among factors investigated as risk factors for chronification of headache disorders, familial liability for CH and drug overuse has been rarely investigated. Patients and Methods.— A total of 105 consecutive patients with daily or nearly daily headache, and 102 consecutive patients with episodic headache matched by age, sex, and type of headache at onset, underwent a structured direct interview about family history for episodic headache, CH with and without medication overuse, substance abuse/dependence, and psychiatric disorders. Results.— In total, 80 out of 105 patients with CH received a diagnosis of medication overuse headache (MOH), 21 patients were classified as chronic migraine (CM), and 4 as chronic tension‐type headache (CTTH) without drug overuse. Some 38.1% of CH patients reported family history for CH vs only 13.7% of episodic headaches (P = .001). Familiality for CH with medication overuse was reported by 25.7% of cases vs 9.8% of controls (P = .0028). A familial history of substance abuse was reported by 20% of patients vs 5.9% of controls (P = .0026). In all, 28.7% of MOH patients reported family history for CH with medication overuse (P = .0014) and 21.2% for substance abuse (P = .002). Relatives of patients with MOH were more likely than control relatives to suffer from CH (OR = 4.19 [95% CI 2.05‐8.53]), drug overuse (OR = 3.7 [95% CI 1.66‐8.24]), and substance abuse (OR = 4.3 [95% CI 1.65‐11.19]). No differences regarding family history for episodic headache and for psychiatric disorders were found. No differences in family history for CH with drugs overuse and for substance abuse were found between CH patients without overuse and controls. Fifteen CH patients reported family history for alcohol abuse (P = .0003). Conclusions.— The significantly increased familial risk for CH, drug overuse, and substance abuse suggests that a genetic factor is involved in the process of headache chronification.     

Long-term follow-up of patients treated for chronic headache with analgesic overuse

The study aim is to describe the long-term clinical outcome of 102 chronic headache patients with analgesic daily use. They were assessed for daily drug intake (DDI), headache index (HI) and quality of life (QoL) and compared with a parallel group of patients with active chronic daily headache but no analgesic overuse. For the primary study group, baseline 1995 DDI was 1.80 +/- 1.87 and did not differ significantly in 1999. Patients who daily continued to use analgesics had a higher 1995 baseline DDI (t = 2.275, P = 0.025), a longer drug abuse history (t = 2.282, P = 0.025) and a higher DDI (t = 4.042, P < 0.001) 4 years later. At 4 years of follow-up, only one-third of patients initially treated for chronic daily headache and analgesic overuse are successful in refraining from chronic overuse. Those subjects appear to have a persistence for combination analgesic agents; however, their QoL is slightly better than that of patients who revert to episodic headache or continue with chronic daily headache but do not overuse analgesic agents. Persistent analgesic overuse seems to be linked to the length of abuse and to the number of drugs ingested.     

Chronic frequent headache in the general population: prevalence and associated factors

We studied the prevalence and short-term natural course of chronic frequent headache (CFH) in the general population and identified risk factors. In the Netherlands everyone is registered at a single general practice. We sent questionnaires to all persons (n = 21 440) aged 25-55 years, registered at 16 general practices. We compared the characteristics of 177 participants with CFH (>14 headache days/month for >3 months) with 141 participants with infrequent headache (1-4 days/month) and 526 without headache (<1 day/month). The prevalence of CFH was 3.7% [95% confidence interval (CI) 3.4, 4.0]. In 5 months, 12% showed a clinically relevant decrease to <7 days/month. In both headache groups 70% were women vs. 41% in the group without headache. Compared with the group with infrequent headache, the CFH group had more subjects with low educational level [35% vs. 11%; odds ratio (OR) 4.3, 95% CI 2.3, 7.8], medication overuse (62% vs. 3%; OR 38.4, 95% CI 13.8, 106.9), sleeping problems (44% vs. 8%; OR 8.1, 95% CI 3.6, 18.1), a history of head/neck trauma (36% vs. 14%; OR 4.0, 95% CI 2.2, 7.1), high scores on the General Health Questionnaire (62% vs. 34%; OR 2.7, 95% CI 1.3, 3.6) and more smokers (45% vs. 19%; OR 3.1, 95% CI 1.9, 5.3). We conclude that headache frequency fluctuates. CFH is common and associated with overuse of analgesics, psychopathology, smoking, sleeping problems, a history of head/neck trauma and low educational level. Female sex is a risk factor for headache, not for chronification of headache.     

Predictors of hazardous alcohol consumption among patients with cluster headache

The purpose of this study was to identify predictors of hazardous alcohol consumption in patients with cluster headache (CH). We investigated 246 German CH patients with the Alcohol Use Disorders Identification Test (AUDIT). The average daily alcohol consumption was 6.5 g. Predictors for hazardous drinking (AUDIT>or=5 points; 21.5% of patients) were male gender [odds ratio (OR) 4.15, 95% confidence interval (CI) 1.35, 12.71], episodic as opposed to chronic CH (OR 4.8, 95% CI 1.38, 16.67) and a low demanding job as opposed to a high demanding job (OR 2.28, 95% CI 1.15, 4.51). Our data indicate that CH patients drink less alcohol compared with the German population and that CH seems to protect against hazardous alcohol consumption. Moreover, predictors for hazardous alcohol consumption in CH patients are not different from the general population.     

Topiramate in patients with episodic migraine: reducing the risk for chronic forms of headache

OBJECTIVE: The aim was to evaluate whether preventive treatment with topiramate in patients with episodic migraine reduces the risk of developing chronic forms of headache. BACKGROUND: Chronic forms of headache, including chronic migraine or medication overuse headache (MOH), are characterized by 15 or more headache days per month. Acute medication overuse has been shown to be a risk factor for developing chronic headache, but it is not known whether preventive treatment can reduce the risk of developing chronic forms of headache or the development of MOH. METHODS: Pooled data from 3 trials in patients with episodic migraine randomized either to treatment with 100 mg topiramate per day (n = 384) or with placebo (n = 372) were analyzed with regard to the number of headache days during a prospective 4-week baseline period and the individual final 4 weeks of each patient's treatment during the planned 26-week double-blind treatment period. RESULTS: The number of headache days per month in the topiramate versus the placebo-treated groups was 7.3 +/- 3.0 versus 7.3 +/- 3.1 during baseline and 4.1 +/- 4.2 versus 5.6 +/- 4.9 during the final 4 weeks, respectively (P < .001). At the end of the study, 8 versus 16 patients fulfilled International Headache Society criteria of chronic headache (odds ratio: 2.11, P= .082). Moreover, a significantly lower number of patients receiving topiramate treatment reported an increase in headache days per month by the end of the study when compared to placebo (66 vs 88 patients, respectively; odds ratio: 1.49, P < .05). Finally, the number of days with usage of acute medication was significantly lower in the topiramate arm compared with placebo (3.3 +/- 3.7 vs 4.3 +/- 3.6, respectively; P < .001). CONCLUSION: Preventive treatment with topiramate in patients with episodic migraine may reduce the risk of developing chronic forms of headache.     

Transformed migraine and medication overuse in a tertiary headache centre--clinical characteristics and treatment outcomes

Studies suggest that a substantial proportion of headache sufferers presenting to headache clinics may overuse acute medications. In some cases, overuse may be responsible for the development or maintenance of a chronic daily headache (CDH) syndrome. The objectives of this study are to evaluate patterns of analgesic overuse in patients consulting a headache centre and to compare the outcomes in a group of patients who discontinued medication overuse to those of a group who continued the overuse, in patients with similar age, sex and psychological profile. We reviewed charts of 456 patients with transformed migraine (TM) and acute medication overuse defined by one of the following criteria: 1. Simple analgesic use (>1000 mg ASA/acetaminophen) > 5 days/week; 2. Combination analgesics use (caffeine and/or butalbital) > 3 tablets a day for > 3 days a week; 3. Opiate use > 1 tablet a day for > 2 days a week; 4. Ergotamine tartrate use: 1 mg PO or 0.5 mg PR for > 2 days a week. For triptans, we empirically considered overuse > 1 tablet per day for > 5 days per week. Patients who were able to undergo detoxification and did not overuse medication (based on the above definition) after one year of follow-up were considered to have successful detoxification (Group 1). Patients who were not able to discontinue offending agents, or returned to a pattern of medication overuse within one year were considered to have unsuccessful detoxification (Group 2). We compared the following outcomes after one year of follow-up: Number of days with headache per month; Intensity of headache; Duration of headache; Headache score (frequency x intensity). The majority of patients overused more than one type of medication. Numbers of tablets taken ranged from 1 to 30 each day (mean of 5.2). Forty-eight (10.5%) subjects took >10 tablets per day. Considering patients seen in the last 5 years, we found the following overused substances: Butalbital containing combination products, 48%; Acetaminophen, 46.2%; Opioids, 33.3%; ASA, 32.0%; Ergotamine tartrate, 11.8%; Sumatriptan, 10.7%; Nonsteroidal anti-inflammatory medications other than ASA, 9.8%; Zolmitriptan, 4.6%; Rizatriptan, 1.9%; Naratriptan, 0.6%. Total of all triptans, 17.8%. Of 456 patients, 318 (69.7%) were successfully detoxified (Group 1), and 138 (30.3%) were not (Group 2). The comparison between groups 1 and 2 after one year of follow-up showed a decrease in the frequency of headache of 73.7% in group 1 and only 17.2% in group 2 (P < 0.0001). Similarly, the duration of head pain was reduced by 61.2% in group 1 and 14.8% in group 2 (P < 0.0001). The headache score after one year was 18.8 in group 1 and 54 in group 2 (P < 0.0001). A total of 225 (70.7%) successfully detoxified subjects in Group 1 returned to an episodic pattern of migraine, compared to 21 (15.3%) in Group 2 (P < 0.001). More rigorous prescribing guidelines for patients with frequent headaches are urgently needed. Successful detoxification is necessary to ensure improvement in the headache status when treating patients who overuse acute medications.     

Neoatherosclerosis assessed with optical coherence tomography in restenotic bare metal and first- and second-generation drug-eluting stents

Although reported in bare metal stents (BMS) and first-generation drug-eluting stents (DES), little is known about neoatherosclerosis in second-generation DES. We used optical coherence tomography to evaluate neoatherosclerosis among different stent generations. Overall, 274 in-stent restenosis (ISR) lesions (duration from implantation 56.9?±?47.2 months) in 274 patients were assessed for the presence of neoatherosclerosis. Neoatherosclerosis was identified in 38.7% of lesions (106/274): 23.0% second-generation DES (38/165), 65.1% first-generation DES (54/83), and 53.8% BMS (14/26). In the neoatherosclerosis cohort (n?=?106), more stent underexpansion or fracture/deformation was observed in second-generation DES, whereas thrombus, without plaque rupture, or evagination was more common in first-generation DES. In multivariable analyses, duration from implantation >1 year (OR: 2.44, 95% CI 1.12–5.31; p?=?0.03), absence of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (OR 1.95, 95% CI 1.10–3.44; p?=?0.02) or statins at the time of ISR (OR 3.12, 95% CI 1.42–6.84; p?=?0.01), and first-generation vs first-generation DES (OR 5.32, 95% CI 2.82–10.10; p?<?0.001) correlated with a higher prevalence of neoatherosclerosis. Duration from implantation <1 year (OR 2.17, 95% CI 1.03–4.55; p?=?0.04) and thin fibrous cap, thrombus, or rupture (OR 2.72, 95% CI 1.15–6.39; p?=?0.02) were independent predictors for acute coronary syndromes presentation. Neoatherosclerosis is an important ISR mechanism, especially in first generation DES.     

Medication overuse headache: predictors and rates of relapse in migraine patients with low medical needs. A 1-year prospective study

The aim of this study was to evaluate the rates and predictors of relapse, after successful drug withdrawal, in migraine patients with medication overuse headache (MOH) and low medical needs. The study population, study design, inclusion criteria and short-term effectiveness of the medication withdrawal strategies have been described elsewhere (Rossi et al., Cephalalgia 2006; 26:1097). Relapsers were defined as those patients fulfilling, at follow-up, the new International Classification of Headache Disorders, 2nd edn, appendix criteria for MOH. Complete datasets were available for 83 patients. At 1 year's follow up, the relapse rate was 20.5%. Univariate analysis showed that patients who relapsed had a longer duration of migraine with more than eight headache days/month, a longer duration of drug overuse, had tried a greater number of preventive treatments in the past, had a lower reduction of headache frequency after withdrawal, and had previously consulted a greater number of specialists. Binary logistic regression analysis was performed, and three variables emerged as significant predictors of relapse: duration of migraine with more than eight headache days/month [odds ratio (OR) 1.57, P = 0.01], a higher frequency of migraine after drug withdrawal (OR 1.48, P = 0.04) and a greater number of previous preventive treatments (OR 1.54, P = 0.01). In patients with migraine plus MOH and low medical needs, relapse seems to depend on a greater severity of baseline migraine.     

Clinical differences between immigrants voluntarily and involuntarily admitted to acute psychiatric units: a 3-year prospective study

Involuntary psychiatric admissions are widespread among patients with an immigrant background. According to a study in Norway, involuntary admissions are about 75% of admissions among immigrants compared to roughly 50% among ethnic Norwegians. The aim of the present study was to compare clinical and demographic characteristics of immigrant patients with involuntary or voluntary admissions to two acute psychiatric units. A 3-year prospective study of 94 immigrant patients involuntarily and voluntarily admitted to acute psychiatric units was carried out. Sixty-two patients (66.0%) were voluntarily and 30 (31.9%) involuntarily admitted. Involuntary admissions were significantly higher among men (22, 73.3%) compared to women (8, 26.7%; χ(2) = 4.507, d.f. = 1, P= 0.03). The mean length of stay for voluntary and involuntary patients were 7.8 (SD = 6.6) and 21.6 (SD = 27.3; t=-2.7, d.f. = 88, P= 0.01). Patients diagnosed with schizophrenia and psychotic disorder were more often admitted involuntarily (63.0%; χ(2) = 17.83, P= 0.001). This study confirms that immigrant patients diagnosed with psychotic disorders are more often involuntarily than voluntarily admitted. Comparing the clinical and demographic characteristics of immigrants helps identify the reasons behind involuntary admissions and might improve efforts towards reducing such admissions in the future.     

First-generation versus second-generation drug-eluting stents in patients with chronic kidney disease: a systematic review and meta-analysis

Background: Chronic kidney disease (CKD) patients are associated with very high rate of adverse cardiovascular outcomes after drug-eluting stents (DES) implantation. The clinical outcomes of second-generation DES versus first-generation DES in CKD patients remain controversial.

Objective: The aim of the current study was to perform a systematic review and meta-analysis to assess the safety and efficacy of second-generation DES versus first-generation DES in CKD patients.

Methods: A systematical search of databases of PubMed, EMBASE, and Cochrane Library was conducted for eligible studies comparing the clinical outcomes of first-generation DES versus second-generation DES. Sirolimus-eluting and paclitaxel-eluting stents were classified as first-generation DES, and everolimus-eluting, zotarolimus-eluting, and biolimus-eluting stent (BES) were classified as second-generation DES. A pooled odds ratio (OR) and 95% confidence interval (CI) were used to summary the estimates. Heterogeneity, subgroup analysis, sensitivity analysis and publication bias were also performed.

Results: We identified 14 trials involving 9,542 patients with CKD undergoing percutaneous coronary intervention. First-generation DES implantation was associated with higher risk of long-term all-cause mortality (OR, 1.31; 95% CI, 1.02–1.69; P = 0.04; I² = 0%), in stent restenosis (OR, 1.69; 95% CI, 1.14–2.49; P = 0.008; I² = 49%) and stent thrombosis (OR, 1.64; 95% CI, 1.00–2.69; P = 0.05; I² = 49%) compared with second-generation DES implantation. First-generation DES and second-generation DES showed similar efficacy in decreasing risk of repeat revascularization, myocardial infarction (MI), or major adverse cardiac events (MACE) between first-generation and second-generation DES implantation.

Conclusions: In CKD patients, the use of second-generation DES was associated with lower risk of long-term all-cause mortality, in stent restenosis and stent thrombosis as compared with first-generation DES. No differences were found regarding repeat revascularization, MI, and MACE.     

Does medication overuse headache represent a behavior of dependence?

Medication overuse is relatively common in patients with frequent headache. To explore the prevalence of patients who meet the criteria for substance dependence in Diagnostic and Statistical Manual of Mental Disorders, Edition IV (DSM-IV), and to identify variables of substance dependence among patients with chronic daily headache, we recruited consecutive patients with chronic daily headache at a headache clinic from November 1999 to June 2004. Each patient completed a headache intake form, a dependence questionnaire modified from DSM-IV, and the Hospital Anxiety and Depression Scale (HADS). The presence of probable medication overuse headache (pMOH) was defined on the basis of the International Classification of Headache Disorders, 2nd edition, 2004. A total of 1,861 patients with chronic daily headache (1,369 women, 492 men; mean age, 49.6+/-15.4 years) were recruited. Almost half (895/1,861, 48%) met criteria of pMOH, and 606 of these patients (606/895, 68%) met three of five DSM-IV substance dependence criteria. In contrast, only 191 of 968 patients without pMOH (20%) met the DSM-IV criteria (OR=8.6, [7.0-10.6], chi-square test, P<0.001). Patients who fulfilled DSM-IV criteria of dependence had higher numbers of physician appointments in the past year. Multivariate logistic regression analyses revealed that migraine headache, frequent physician consultation, intensity of headache, and presence of a higher anxiety score were significant independent variables for substance dependence. Among patients with chronic daily headache, pMOH was associated with behaviors of substance dependence.     

Depression and anxiety: effect on the migraine-obesity relationship

OBJECTIVE: To discern the effects of depression and anxiety on the migraine-obesity relationship. BACKGROUND: Migraine and obesity are highly prevalent conditions and are both independently linked to psychiatric conditions, mainly depression and anxiety. METHODS: Data are from an ongoing cross-sectional multicenter study on comorbid conditions in clinic patients seeking treatment for headache. The diagnosis of migraine was determined by the examining physician based on the International Classification of Headache Disorders (ICHD)-II criteria. Participants completed a self-administered questionnaire with information on demographics, headache features, and physician-diagnosed comorbid medical and psychiatric disorders. The questionnaire included scales for measuring current depression (PHQ-9), anxiety (BAI), and headache-related disability (HIT-6). RESULTS: A total of 721 migraineurs (88% women) from 8 different headache treatment centers were included in this study (mean age = 42 years, SD = 12). Aura was reported in 45% and chronic headache (>or=15 headache days/month) in 35% of the participants. Prevalence of obesity in our population was 30% and only 38% had normal weight. Obesity was more common in men (P= .004), African Americans (P= .026), and in lower education (P= .05) and household income (P=.05) groups. Current depression (PHQ-9 score >or=10) was noted in 42% and current anxiety (BAI score >or=8) in 70% of the obese migraineurs. In ordinal logistic regression, obesity was associated with current depression (odds ratio [OR]= 1.86, 95% confidence interval [CI]: 1.25 to 2.78) and anxiety (OR = 1.58, 95% CI: 1.12 to 2.22). A significant effect of depression on the body mass index (BMI) and headache frequency relationship was noted. Obese migraineurs with depression were more likely to have higher headache frequency (OR = 4.16, 95% CI: 1.92 to 8.99) and headache-related disability (OR = 7.10, 95% CI: 2.69 to 18.77) compared to normal weight migraineurs without depression. Similarly, obese migraineurs with anxiety were more likely to have higher headache frequency (OR = 1.96, 95% CI: 1.07 to 3.61) and headache-related disability (OR = 3.59, 95% CI: 1.64 to 7.86) compared to normal weight migraineurs without depression. Compared to migraineurs with either current depression or anxiety, those with both these conditions were more likely to have higher headache frequency (OR = 3.18, 95% CI: 1.86 to 5.43) and headache disability (OR = 6.13, 95% CI: 2.58 to 14.59). CONCLUSION: Depression and anxiety were common in obese migraineurs. The relationship of obesity with migraine frequency and migraine-related disability is modified by depression and by anxiety, with the strongest effect observed in migraineurs with both depression and anxiety.     

Use of complementary and alternative medicine by patients with cluster headache: results of a multi-centre headache clinic survey

OBJECTIVES: To evaluate the rates, pattern, satisfaction with, and presence of predictors of complementary and alternative medicine (CAM) use in a clinical population of patients with cluster headache (CH). DESIGN AND SETTING: One hundred CH patients attending one of three headache clinics were asked to undergo a physician-administered structured interview designed to gather information on CAM use. RESULTS: Past use of CAM therapies was reported by 29% of the patients surveyed, with 10% having used CAM in the previous year. Only 8% of the therapies used were perceived as effective, while a partial effectiveness was reported in 28% of CAM treatments. The most common source of recommendation of CAM was a friend or relative (54%). Approximately 62% of CAM users had not informed their medical doctors of their CAM use. The most common reason for deciding to try a CAM therapy was that it offered a "potential improvement of headache" (44.8%). Univariate analysis showed that CAM users had a higher income, had a higher lifetime number of conventional medical doctor visits, had consulted more headache specialists, had a higher number of CH attacks per year, and had a significantly higher proportion of chronic CH versus episodic CH. A binary logistic regression analysis was performed and two variables remained as significant predictors of CAM use: income level (OR=5.7, CI=1.6-9.1, p=0.01), and number of attacks per year (OR=3.08, CI=1.64-6.7, p<0.0001). CONCLUSION: Our findings suggest that CH patients, in their need of and quest for care, seek and explore both conventional and CAM approaches, even though only a very small minority finds them very satisfactory.     

Association of the IL-1RN2 allele with periodontal diseases

OBJECTIVES: Interleukin-1 receptor antagonist (IL-1Ra) gene (IL-1RN) polymorphism is associated with disease susceptibility and activity in several inflammatory diseases. The aim of this study was to investigate IL-1RN genotype and its associations with different periodontal diseases in a group of Turkish subjects. DESIGN AND METHODS: A total of 293 subjects were included in this study. Genomic DNA was obtained from the peripheral blood of 52 patients with generalized aggressive periodontitis (G-AgP), 51 with chronic periodontitis (CP) and 190 reference subjects. A variable number tandem repeat (VNTR) polymorphism in the second intron of the IL-1RN gene was detected by PCR-based methods. Probing pocket depth, clinical attachment loss, plaque accumulation and bleeding on probing (BOP) were recorded. The data were analyzed by the chi(2) test, logistic regression and Mann-Whitney U test. RESULTS: There were significant differences among the groups in the distribution of IL-1RN genotypes (P = 0.0001) and allele frequencies (P = 0.0001). The frequency of IL-1RN2 allele 2 positivity was higher in the AgP and CP group than the reference group [odds ratio (OR) 6.654, 95% CI: 3.023-16.648; OR 10.327, 95% CI: 4.758-22.412, respectively]. The percentage of sites with BOP was significantly higher in IL-1RN2+ compared to IL-1RN2- CP patients (P = 0.022). CONCLUSION: These results suggest that IL-1RN2 allele positivity is associated with periodontal disease in a Turkish population.     

Factors determining headache at onset of acute ischemic stroke

Headache is a frequent accompaniment of acute ischaemic stroke. The predisposing factors and underlying mechanisms are currently incompletely defined. We analysed prospectively collected data relevant to headache occurring at ischaemic stroke onset in consecutive patients included in the Henry Ford Hospital Stroke Data Bank. Patients with headache (HA+) and without headache (HA-) were compared for demographic factors, medical history, medications, examination findings, laboratory findings, and stroke localization and subtype. Group comparisons for categorical data were performed with chi(2) test, and for continuous variables with two-sample t-tests. Stepwise logistic regression analysis, including all variables with P<0.25, was used to define the independent predictors of onset headache. Three hundred and seventy-five patients had complete headache and clinical datasets and were included in the analysis (HA+, N=118; HA-, N=257). Multivariate analysis revealed that the independent predictors of HA+ were: infarct in the distribution of the posterior circulation [P=0.0076, odds ratio (OR) 2.15, 95% confidence interval (CI) 1.23, 3.77], absence of history of hypertension (P=0.0106, OR 0.48, 95% CI 0.27, 0.84), and treatment with warfarin at the time of the index stroke (P=0.0135, OR 4.89, 95% CI 1.39, 17.21). The occurrence of headache at onset of ischaemic stroke is determined by posterior circulation distribution of the ischaemic event, absence of history of hypertension and treatment with warfarin at the time of the index stroke. These results suggest that preserved elasticity and maintenance of the intracranial vasculature in a relaxed state, in combination with coagulation system derangements, and activation of dense perivascular afferent nerves, play a role in the pathogenesis of onset headache.     

Combined pharmacological and short-term psychodynamic psychotherapy for probable medication overuse headache: a pilot study

We studied the effects of short-term psychodynamic psychotherapy (STPP) and pharmacological therapy in 26 consecutive patients with probable medication overuse headache (pMOH). Patients underwent a standard in-patient detoxification protocol, lasting a mean of 7 days. Eleven patients overused non-steroidal anti-inflammatory drugs (NSAIDs), five a combination of NSAIDs and triptans, four triptans, four a combination of NSAIDs, and three triptans and ergot derivates. Preventive therapy was initiated during detoxification. The STPP protocol comprised the Brief Psychodynamic Investigation (BPI) and psychoanalysis-inspired psychotherapy. All patients (groups A and B) underwent the BPI and pharmacological therapy. Half of the patients (group B) also not randomly underwent psychoanalysis-inspired psychotherapy. We found a significant interaction between time and group for headache frequency and medication intake. At 12-month follow-up, a statistically greater decrease in headache frequency and medication intake was observed in group B than in group A ( P  = 0.0108 and P  = 0.0097, respectively). The relapse rate was much lower in group B patients at both 6 and 12 months [15.3%, odds ratio (OR) 0.11, P  = 0.016, and 23%, OR 0.18, P  = 0.047, respectively] than in group A. The risk of developing chronic migraine (CM) during follow-up was higher in group A than in group B at 6 (OR 2.0, P  = 0.047) and 12 months (OR 2.75, P  = 0.005). Our study suggests that STPP in conjunction with drug withdrawal and prophylactic pharmacotherapy relieves headache symptoms in pMOH, reducing both long-term relapses and the burden of CM.     

Behavioral Risk Factor and Preventive Health Care Practice Survey of Immigrants in the Emergency Department

OBJECTIVE: To compare the demographic profiles, behavioral risk factors, and preventive health care practices of adult immigrant and non-immigrant patients while considering the effects of various socioeconomic variables. METHODS: This was a prospective survey administered at a large urban emergency department in New York City. Study subjects were adult immigrant patients presenting in an eight-week period in 1998. One non-immigrant control patient was recruited concurrently with every two immigrant patients. Differences between immigrants and non-immigrants were evaluated using the chi-square test. Multivariate logistic regression models were used to adjust for confounding variables. RESULTS: Eight hundred sixty-nine immigrant patients from 80 countries and 354 non-immigrant patients completed surveys. Immigrants were more likely not to have reached high school (28.9% vs 8.5%; p < 0.001), to have annual family incomes less than $20,000 (73.8% vs 64.5%; p < 0.01), and to have no health coverage (51.7% vs 30.8%; p < 0.001). Immigrant women were more likely never to have had a Papanicolaou test (16.1% vs 1.4%; OR 11.24, 95% CI = 2.70 to 46.8) and never to have performed a self-breast examination (20.8% vs 7.5%; OR 2.03, 95% CI = 1.29 to 3.20). Immigrants were more likely not to use condoms (63.4% vs 42.8%; OR 1.61, 95% CI = 1.20 to 2.15) and never to have visited a dentist (21.2% vs 7.8; OR 2.54, 95% CI = 1.60 to 4.04). Immigrants were more likely never to have received a purified protein derivative (PPD) skin test (30.3% vs 9.1%; OR 3.85, 95% CI = 2.56 to 5.80) and never to have received a tetanus immunization (48.1% vs 13.5%; OR 3.09, 95% CI = 2.17 to 4.42). These differences were independent of age, gender, marital status, employment, education, income, and health insurance status. When analyzing the immigrant group alone, region of origin, length of time in the United States, and English ability were significant independent predictors of higher-risk behavioral profiles and poor preventive health care practices. CONCLUSIONS: Differences exist between the socioeconomic profiles, behavioral risk profiles, and preventive health care practices of immigrant and non-immigrant patients presenting to a large inner-city municipal emergency department. Different populations within a heterogeneous group of immigrants have distinct health risks and public health needs.     

Serotonergic activity contributes to analgesic overuse in chronic tension-type headache

OBJECTIVE: To evaluate the possible existence of a genetically determined innate factor that could exert a profound influence on the development of analgesic overuse in chronic tension-type headache (CTTH). BACKGROUND: Many patients with CTTHs report the regular use of analgesics. Continuous use of analgesics results in the ultimate worsening of headaches. The factors related to development of analgesic overuse, however, remain poorly understood. The genetic factors for serotonin metabolism and the harm avoidance (HA) personality dimension are known to be associated with various substance abuse patterns. DESIGN: We performed serotonin transporter protein (5-HTT) gene-linked polymorphic region (5-HTTLPR) genotype polymorphism analyses, and investigated serotonin-related personality traits by assessing the HA dimension using tridimensional personality questionnaire, given to 48 patients with CTTHs and reported analgesic overuse (CTTH-AO), in 50 patients with CTTHs without analgesic overuse (CTTH-NO), and in 100 healthy controls. We compared their headache characteristics using standardized questionnaires. RESULTS: We discovered an excess frequency of 5-HTTLPR short allele and a different genotypic distribution in patients with CTTH-AO. The S/S genotype frequency was significantly higher in patients with CTTH-AO (83%) than in CTTH-NO (72%) and control (59%; P= .010) groups. Patients with CTTH-AO exhibited the highest HA scores (23.3 +/- 5.4), as compared to CTTH-NO (19.9 +/- 6.7) and control (16.3 +/- 6.1) groups. Individuals with the S/S genotype showed a greater tendency toward analgesic overuse (13.3 +/- 11.3 days per month) than did those with the non-S/S genotype (7.0 +/- 8.6 days per month: P= .02). CONCLUSIONS: Our data suggest that serotonergic activity may be involved in the development of analgesic overuse in CTTH and that 5-HTTLPR might be one of the genetically contributing factors.     

Almotriptan and its combination with aceclofenac for migraine attacks: a study of efficacy and the influence of auto-evaluated brush allodynia

Early treatment and combining a triptan with a non-steroidal anti-inflammatory drug (NSAID) are thought to improve outcome during migraine attacks, possibly by counteracting the negative influence of cutaneous allodynia. The aim of this multicentre, double-blind pilot study was to evaluate the prevalence of brush allodynia and its relative influence on the efficacy of a triptan-NSAID combination compared with headache intensity at the time of treatment. In a randomized, cross-over design, 112 migraineurs treated two moderate or severe attacks with almotriptan 12.5 mg combined with either aceclofenac 100 mg or placebo. Patients used a 2-cm brush to assess cutaneous allodynia. Allodynia was reported in 34.4% of attacks. The almotriptan-aceclofenac combination was numerically superior to triptan-placebo on 2-24-h sustained pain-free (P = 0.07), 2-h pain-free (P = 0.07) and headache recurrence (P = 0.05) rates, but not on 1-h headache relief. Allodynia numerically reduced treatment success overall, but this effect was not significant for the primary outcome measures. Headache intensity had a significant negative influence on 1-h relief in both attacks (P = 0.0001 and 0.0008, chi(2)) and on 2-24-h sustained pain-free rates in triptan-placebo-treated attacks (P = 0.013). Multivariate logistic regression analysis confirmed that headache intensity at treatment intake, rather than allodynia, significantly influenced most outcome measures, predominantly so in attacks treated with almotriptan and aceclofenac. In the latter, severe compared with moderate headache intensity reduced the likelihood of achieving the primary efficacy end-points [odds ratios (OR) 0.12 and 0.33], whereas allodynia was not a significant explanatory variable (OR 0.76 and 0.65). The results apply to the protocol used here and need to be confirmed in larger studies using quantitative sensory testing.
