Most patients had common migraine per Ad Hoc Committee and World Federation of Neurology Research Group guidelines (83 to 93%) and migraine without aura per International Headache Society (92 keflex 250 mg sale antibiotic 100mg. Use of concomitant analgesics and ergotamines was allowed for abortive migraine treatment. Headache frequency, intensity, severity, duration, and abortive treatment tablet usage efficacy parameters were analyzed using patient diary data. The methods used to assess treatment effects differed across studies. Some of the common outcome results are summarized in Table 13 below. Analysis of variance was used to 117 assess comparative efficacy of metoprolol 200 mg and propranolol 160 mg in 1 trial. Beta blockers Page 44 of 122 Final Report Update 4 Drug Effectiveness Review Project Attack frequency Metoprolol durules 200 mg, metoprolol tartrate 200 mg, and timolol 20 mg all were similar to 117-119, 121, 122 propranolol 160 mg in decreasing 4-week attack frequency rates. A recent, well- conducted systematic review comparing propanol to other beta blockers found that there was little difference between propanol and the comparators (metoprolol, nadolol, timolol) in reducing attack frequency (pooled standard mean difference, −0. In a study comparing nebivolol to metoprolol there were no statistically significant differences in attack frequency, although nebivolol fared better with 125 regards to tolerability. Migraine days There were differences across trials in methods of assessment of this parameter. When the total number of headache days recorded over 42 days across all 28 patients analyzed was considered in the Stensrud trial, no difference between atenolol and propranolol treatment was found. Metoprolol durules and metoprolol tartrate reduced number of migraine days at rates similar to 117-119 propranolol across 3 trials. In a comparison of nebivolol to metoprolol over an 18-week 125 period, no differences were found. Severity Severity rating methods differed across trials. Metoprolol durules, metoprolol tartrate, and 118, 119, timolol all were similar to propranolol at comparable doses in decreasing attack severity. Tablet consumption There were no differences in reduction of acute medication (analgesics, ergots) for metoprolol 118, 119, 121, 122 durules or metoprolol tartrate and propranolol. Moreover, the number of patients 125 using pain medication at endpoint were similar between nebivolol and metoprolol. Subjective assessment 118, 119 Patients in 2 trials were asked to make a subjective assessment of therapeutic improvement using descriptions of marked, moderate, slight, and unchanged or worse. There were no differences found between slow release metoprolol (durules) and propranolol (76% compared with 63%) or between low doses of immediate release metoprolol or propranolol (63% compared with 64%) in rates of decreased frequency of mean or median attacks per month. Miscellaneous 120-122 Two trials measured treatment efficacy using a composite score (attack frequency x severity x duration) and found no differences between atenolol or timolol and propranolol.

One trial did not report propranolol dosage and will be discussed separately. All but 2 trials reported allowing the use of various concomitant medications to abort migraine pain including common analgesics, ergotamines, and narcotics. These trials ranged in duration from 8 to 52 weeks, generally enrolling patients with a 1 to 2 year history of common or classic migraine (Ad Hoc Committee), generally occurring at an average frequency of 3 per week. One trial included only Beta blockers Page 46 of 122 Final Report Update 4 Drug Effectiveness Review Project 130 patients with classic migraine. Patient characteristics reflected the target migraine population, with mean ages in the range of 37 to 39 and gender predominantly female (>75%). Sample sizes ranged from 24 to 259 patients enrolled. Assessment of attack frequency, duration, severity, and use of acute medication variables was made using patient diary card data. Placebo-controlled trial data was consistent with head-to-head trial data for atenolol 100 mg and slow-release metoprolol (durules) 200 mg, but added no additional evidence that is not reported in the head-to-head trials.

Alyea1 1Dana-Farber Cancer Institute, Boston, MA Donor lymphocyte infusions (DLIs) can induce complete and durable remissions in some patients with hematologic malignancies who have relapsed after allogeneic transplantation, providing definitive evidence of a GVL effect. Despite the great promise initially envisioned for DLI as a method to augment GVL after transplantation, it utility is limited by low response rates in diseases other than chronic myelogenous leukemia and by the development of GVHD, the principal complication of DLI. To maximize GVL potency while minimizing toxicity, cellular effectors active in GVL need to be elucidated. Insight into mechanisms of GVL, such as reversal of in situ T-cell exhaustion, may allow identification of patients who will respond to DLI based on the presence of tumor-infiltrating lymphocytes in the BM. Understanding the clinical factors that influence the effectiveness and abrogate the toxicity of DLI, such as cell dose and timing of DLI after transplantation, will allow further optimization of DLI. This chapter reviews novel strategies that maximize the GVL effect of DLI by enhancing activity while limiting toxicity. After T-cell–depleted HSCT, relapse rates of 40%–60% are tion of relapse in patients with hematologic malignancies after seen in CML patients, compared with 10%–20% after non-T-cell– allogeneic transplantation depleted HSCT. Both CD4 and CD8 T-cell subsets demonstrate ● To evaluate new approaches to enhance the efficacy and limit antileukemic activity in vitro and are implicated as active mediators the toxicity of DLI of GVL in clinical trials of DLI. An increase in HLA class I-restricted CD8 cells is noted in patients with myeloma respond- ing to DLI. Tumor-specific antigen donor CD8 T-cell responses Introduction are found after DLI in patients with acute myeloid leukemia (AML), The success of donor lymphocyte infusion (DLI) in inducing myelodysplastic syndrome (MDS), and myelomas that express long-lasting remissions in patients with chronic myelogenous NY-ESO-1 and other cancer testis antigens such as MAGE and leukemia (CML) provides direct evidence of a GVL effect. HLA class II-restricted CD4 cells recognizing minor histo- the first studies were published, other diseases responsive to DLI compatibility antigens (mHAg) can exhibit both helper function and have been identified and manipulations to enhance DLI-mediated cytolytic activity against leukemia cells. Reducing GVHD, the principal selective cytotoxicity against Philadelphia chromosome–positive complication of DLI, is also a focus of investigation. Despite initial 2 clones have been identified in vivo. In addition to conventional promise, the utility of DLI is limited by lower response rates in CD4 and CD8 T cells, unmanipulated DLI products contain relapsed diseases other than CML, disappointing durability in active regulatory T cells (Tregs) capable of exerting suppressive effects on or more aggressive malignancies, lack of an effective strategy for effector T-cell proliferation and activity. The role of this regulatory use as prophylaxis before relapse occurs, and the prevalent toxicity subset in mediating or inhibiting GVL responses is under of GVHD. Studies of responses induced by DLI have elucidated investigation. Mechanisms of effector cell GVL, particularly in HLA-mismatched or haploidentical recipient– activity include the novel mechanism of “awakening” endogenous donor pairings. NK cells appear early during hematopoietic recov- GVL effector cells by reversing T-cell exhaustion in DLI recipients. A correlation between high numbers of immunotherapeutic agents to improve effectiveness. Selection or circulating NK cells and duration of remission is noted in patients depletion of specific lymphocytes subsets, activation ex vivo before after HSCT. Increased understanding of functionally disparate infusion, and targeting of tumor-specific antigens by genetically subsets of NK cells based on KIR (killer-cell immunoglobulin-like modified donor lymphocytes are being pursued. Incorporation of receptor) expression patterns and new efforts at ex vivo activation these novel cellular approaches into use of DLI remains an ongoing and modification of NK cells highlight a role for NK cells in the challenge.
Precision: The likelihood of random errors in the results of a study trusted keflex 750 mg virus 09, meta-analysis, or measurement. The greater the precision, the less the random error. Confidence intervals around the estimate of effect are one way of expressing precision, with a narrower confidence interval meaning more precision. Prospective study: A study in which participants are identified according to current risk status or exposure and followed forward through time to observe outcome. Prevalence: How often or how frequently a disease or condition occurs in a group of people. Prevalence is calculated by dividing the number of people who have the disease or condition by the total number of people in the group. Antihistamines Page 52 of 72 Final Report Update 2 Drug Effectiveness Review Project Probability: The likelihood (or chance) that an event will occur. In a clinical research study, it is the number of times a condition or event occurs in a study group divided by the number of people being studied. Publication bias: A bias caused by only a subset of the relevant data being available. The publication of research can depend on the nature and direction of the study results. Studies in which an intervention is not found to be effective are sometimes not published. Because of this, systematic reviews that fail to include unpublished studies may overestimate the true effect of an intervention. In addition, a published report might present a biased set of results (for example, only outcomes or subgroups for which a statistically significant difference was found). P value: The probability (ranging from zero to one) that the results observed in a study could have occurred by chance if the null hypothesis was true. Q-statistic: A measure of statistical heterogeneity of the estimates of effect from studies. It is calculated as the weighted sum of the squared difference of each estimate from the mean estimate. Random-effects model: A statistical model in which both within-study sampling error (variance) and between-studies variation are included in the assessment of the uncertainty (confidence interval) of the results of a meta-analysis. When there is heterogeneity among the results of the included studies beyond chance, random-effects models will give wider confidence intervals than fixed-effect models. Randomization: The process by which study participants are allocated to treatment groups in a trial. Adequate (that is, unbiased) methods of randomization include computer generated schedules and random-numbers tables. Randomized controlled trial: A trial in which two or more interventions are compared through random allocation of participants. Regression analysis: A statistical modeling technique used to estimate or predict the influence of one or more independent variables on a dependent variable, for example, the effect of age, sex, or confounding disease on the effectiveness of an intervention. Relative risk: The ratio of risks in two groups; same as a risk ratio. Retrospective study: A study in which the outcomes have occurred prior to study entry. Risk: A way of expressing the chance that something will happen. It is a measure of the association between exposure to something and what happens (the outcome). Risk is the same as probability, but it usually is used to describe the probability of an adverse event. It is the rate of events (such as breast cancer) in the total population of people who could have the event (such as women of a certain age).
