Abstract A favorable prognosis and a low rate of leukemic transformation has been attributed to the 5q- syndrome, a myelodysplastic syndrome (MDS) characterized by macrocytic anemia, hypolobulated micromegakaryocytic hyperplasia, and an interstitial deletion of chromosome 5. We examined the characteristics and outcome of 43 consecutive patients in our institution strictly defined by morphologic criteria and a solitary 5q- cytogenetic defect. The median age at diagnosis was 68 years, with a clear female predominance (7:3). Eighty percent of the patients were red blood cell transfusion-dependent at diagnosis and all untransfused patients had macrocytic indexes. In contrast, significant neutropenia or thrombocytopenia was rare. The French-American-British (FAB) class distributions were RA (72%), RARS (7%), RAEB (16%), and RAEB-IT (5%). At a median follow-up of 31 months, 56% of the patients survive, with a projected median survival of 63 months. The incidence of acute leukemia was 16% and was uniformly fatal. Clinical hemosiderosis occurred in 28% of the patients, resulting in two deaths. Neither survival nor the risk of leukemic transformation was predictable from initial clinical parameters, including FAB classification, Bournemouth score, and degree of aneuploidy. The lack of significant neutropenia and thrombocytopenia seemed to account for a very low incidence of infection and bleeding resulting in a prognosis equal or superior to historical patients with MDS. Therapeutic endeavors, including the use of corticosteroids, androgens, cis-retinoic acid, pyridoxine, and danazol, were largely unsuccessful.
A Tale of Two Systems: Cardiac Cephalalgia vs Migrainous Thoracalgia
The practice of headache medicine is challenging, and excluding secondary causes of headaches is essential for proper diagnosis and treatment. The evaluation of secondary headaches often leads to investigations involving organ systems other than the nervous system. As such, headache, which is typically thought to be neurologic in origin, can be a manifestation of cardiac pathology in the form of cardiac cephalalgia. Conversely, chest pain, which is typically thought to be cardiac in origin, could be a manifestation of a neurologic disease process in the form of atypical migraine aura. In the presented cases, we demonstrate headaches that involve cardiac and neurologic pathology with atypical presentations.
Education and Decision Making at the Time of Triptan Prescribing: Patient Expectations vs Actual Practice
Background Optimizing patient satisfaction with their medical care and maximizing patient adherence with treatment plans requires an understanding of patient preferences regarding education and their role in decision making when treatments are prescribed. Objective To assess the congruence between patient expectations and actual practice regarding education and decision making at the time a triptan is prescribed. Methods This multicenter cross‐sectional survey was performed by headache fellow members of the A merican H eadache S ociety H eadache F ellows R esearch C onsortium at their respective tertiary care headache clinics. Migraine patients who were new patients to the headache clinic and who were current triptan users (use within prior 3 months and for ≥1 year) or past triptan users (no use within 6 months; prior use within 2 years) completed questionnaires that assessed the education they received and their role in decision making at the time a triptan was first prescribed as well as their desire for education and participation in decision making when a triptan is prescribed. Results Consistent with patient preference, most participants received the majority of their education about the triptan from the prescriber's office (70.2%). In descending rank order, participants most desired to be informed about how to decide if a triptan should be taken, when during the course of migraine a triptan should be taken, possible side effects, cost, and how to obtain refills. Regarding side effects, most participants preferred to receive education about the most common side effects of a triptan rather than addressing all possible side effects. Regarding triptan dosing, participants desired to be informed in descending order of importance about taking other medications with triptans, how many doses can be taken for each migraine, how many doses can be taken each week/month, what to do if the triptan does not work, and the triptan mechanism of action. The vast majority of participants (92%) preferred that the decision to prescribe a triptan be a joint decision between the patient and the provider. In actual practice, participants were not as involved in decision making as they would like to be, with patients reporting that the prescriber was the sole decision maker 55.1% of the time. Participants had confidence in their providers (87.7%) and generally felt they did a good job educating them about the triptan (71.1%). Conclusions Based on this study, it is clear that patients prefer the shared model approach to medical decision making in regards to the prescription of triptans. The majority of patients received education that was generally consistent with their desires. Patients preferred that the prescribing provider be the primary source of information. The most desired educational topics included when/if a triptan should be taken, the number of times a triptan can be taken for a single migraine, co‐administration with other acute medications, and the most common side effects. Focusing on these topics should enhance patient satisfaction and may improve compliance.
Identifying the Factors Underlying Discontinuation of Triptans
Objective To identify factors associated with triptan discontinuation among migraine patients. Background It is unclear why many migraine patients who are prescribed triptans discontinue this treatment. This study investigated correlates of triptan discontinuation with a focus on potentially modifiable factors to improve compliance. Methods This multicenter cross‐sectional survey (n = 276) was performed at US tertiary care headache clinics. Headache fellows who were members of the American Headache Society Headache Fellows Research Consortium recruited episodic and chronic migraine patients who were current triptan users (use within prior 3 months and for ≥1 year) or past triptan users (no use within 6 months; prior use within 2 years). Univariate analyses were first completed to compare current triptan users to past users for: migraine characteristics, other migraine treatments, triptan education, triptan efficacy, triptan side effects, type of prescribing provider, Migraine Disability Assessment ( MIDAS ) scores and Beck Depression Inventory ( BDI ) scores. Then, a multivariable logistic regression model was selected from all possible combinations of predictor variables to determine the factors that best correlated with triptan discontinuation. Results Compared with those still using triptans (n = 207), those who had discontinued use (n = 69) had higher rates of medication overuse (30 vs 18%, P = .04) and were more likely to have ever used opioids for migraine treatment (57 vs 38%, P = .006) as well as higher MIDAS (mean 63 vs 37, P = .001) and BDI scores (mean 10.4 vs 7.4, P = .009). Compared with discontinued users, current triptan users were more likely to have had their triptan prescribed by a specialist (neurologist, headache specialist, or pain specialist) (74 vs 54%, P = .002) and were more likely to report headache resolution (53 vs 14%, P < .001) or a reduction in pain intensity (71 vs 28%, P < .001) most of the time from their triptan. On a 1‐5 scale (1 = disagree, 5 = agree), triptan users felt they had more: control over their migraine attacks (2.9 vs 2.1), confidence in their prescribing provider (4.5 vs 4.0), and were more educated about triptan use (4.2 vs 3.7) compared with triptan discontinuers ( P < .001 for all comparisons). Although both current and prior users reported similar rates of side effects (48 vs 43%, P = .44), of those who discontinued use, the main reasons were for lack of effect (44%) and side effects (29%). Our multivariable modeling revealed that the strongest correlate of triptan discontinuation was lack of efficacy (odds ratio = 17, 95% confidence interval [8.8, 33.0]). Other factors associated with discontinuation included MIDAS > 24 (2.6, [1.5, 4.6]), BDI >4 (2.5, [1.4, 4.5]), and a history of ever using opioids for migraine therapy (2.2, [1.3, 3.8]). Having a triptan prescribed by a specialist and using at least 1 other abortive medication with the triptan were associated with a decreased likelihood of triptan discontinuation (0.41, [0.2‐0.7] and 0.44 [0.3, 0.8], respectively). Conclusions As expected, discontinuation was most correlated with lack of efficacy, but other important factors associated with those who had discontinued use included greater migraine‐related disability, depression, and the use of opioids for migraine attacks. Compared with patients who had discontinued triptans, current triptan users felt more: educated about their triptan, control over their migraine attacks, and confidence in their prescribing provider. Current triptan users had their triptan prescribed by a specialist and used other abortive medications with their triptan more often compared with patients who had discontinued triptans. Given the cross‐sectional nature of this study, we cannot determine if these factors contributed to triptan discontinuation or reflect the impact of such discontinuation. Interventions that address modifiable risk factors for triptan discontinuation may decrease the likelihood of triptan discontinuation and thus improve overall migraine control. Because lack of efficacy was most strongly associated with triptan discontinuation, future research should determine why triptans are effective for some patients but not others.
