RESUMO

BACKGROUND & AIMS: Methotrexate and infliximab are effective therapies for Crohn's disease (CD). In the combination of maintenance methotrexate-infliximab trial, we evaluated the potential superiority of combination therapy over infliximab alone. METHODS: In a 50-week, double-blind, placebo-controlled trial, we compared methotrexate and infliximab with infliximab alone in 126 patients with CD who had initiated prednisone induction therapy (15-40 mg/day) within the preceding 6 weeks. Patients were assigned randomly to groups given methotrexate at an initial weekly dose of 10 mg, escalating to 25 mg/week (n = 63), or placebo (n = 63). Both groups received infliximab (5 mg/kg of body weight) at weeks 1, 3, 7, and 14, and every 8 weeks thereafter. Prednisone was tapered, beginning at week 1, and discontinued no later than week 14. The primary outcome was time to treatment failure, defined as a lack of prednisone-free remission (CD Activity Index, <150) at week 14 or failure to maintain remission through week 50. RESULTS: Patients' baseline characteristics were similar between groups. By week 50, the actuarial rate of treatment failure was 30.6% in the combination therapy group compared with 29.8% in the infliximab monotherapy group (P = .63; hazard ratio, 1.16; 95% confidence interval, 0.62-2.17). Prespecified subgroup analyses failed to show a benefit in patients with short disease duration or an increased level of C-reactive protein. No clinically meaningful differences were observed in secondary outcomes. Combination therapy was well tolerated. CONCLUSIONS: The combination of infliximab and methotrexate, although safe, was no more effective than infliximab alone in patients with CD receiving treatment with prednisone.

RESUMO

BACKGROUND & AIMS: Interobserver differences in endoscopic assessments contribute to variations in rates of response to placebo in ulcerative colitis (UC) trials. We investigated whether centralized review of images could reduce these variations. METHODS: We performed a 10-week, randomized, double-blind, placebo-controlled study of 281 patients with mildly to moderately active UC, defined by an Ulcerative Colitis Disease Activity Index (UCDAI) sigmoidoscopy score ≥2, that evaluated the efficacy of delayed-release mesalamine (Asacol 800-mg tablet) 4.8 g/day. Endoscopic images were reviewed by a single expert central reader. The primary outcome was clinical remission (UCDAI, stool frequency and bleeding scores of 0, and no fecal urgency) at week 6. RESULTS: The primary outcome was achieved by 30.0% of patients treated with mesalamine and 20.6% of those given placebo, a difference of 9.4% (95% confidence interval [CI], -0.7% to 19.4%; P = .069). Significant differences in results from secondary analyses indicated the efficacy of mesalamine. Thirty-one percent of participants, all of whom had a UCDAI sigmoidoscopy score ≥2 as read by the site investigator, were considered ineligible by the central reader. After exclusion of these patients, the remission rates were 29.0% and 13.8% in the mesalamine and placebo groups, respectively (difference of 15%; 95% CI, 3.5%-26.0%; P = .011). CONCLUSIONS: Although mesalamine 4.8 g/day was not statistically different from placebo for induction of remission in patients with mildly to moderately active UC, based on an intent-to-treat analysis, the totality of the data supports a benefit of treatment. Central review of endoscopic images is critical to the conduct of induction studies in UC; ClinicalTrials.gov Number, NCT01059344.

RESUMO

BACKGROUND: The efficacy of arthroscopic surgery for the treatment of osteoarthritis of the knee is unknown. METHODS: We conducted a single-center, randomized, controlled trial of arthroscopic surgery in patients with moderate-to-severe osteoarthritis of the knee. Patients were randomly assigned to surgical lavage and arthroscopic débridement together with optimized physical and medical therapy or to treatment with physical and medical therapy alone. The primary outcome was the total Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score (range, 0 to 2400; higher scores indicate more severe symptoms) at 2 years of follow-up. Secondary outcomes included the Short Form-36 (SF-36) Physical Component Summary score (range, 0 to 100; higher scores indicate better quality of life). RESULTS: Of the 92 patients assigned to surgery, 6 did not undergo surgery. Of the 86 patients assigned to control treatment, all received only physical and medical therapy. After 2 years, the mean (+/-SD) WOMAC score for the surgery group was 874+/-624, as compared with 897+/-583 for the control group (absolute difference [surgery-group score minus control-group score], -23+/-605; 95% confidence interval [CI], -208 to 161; P=0.22 after adjustment for baseline score and grade of severity). The SF-36 Physical Component Summary scores were 37.0+/-11.4 and 37.2+/-10.6, respectively (absolute difference, -0.2+/-11.1; 95% CI, -3.6 to 3.2; P=0.93). Analyses of WOMAC scores at interim visits and other secondary outcomes also failed to show superiority of surgery. CONCLUSIONS: Arthroscopic surgery for osteoarthritis of the knee provides no additional benefit to optimized physical and medical therapy. (ClinicalTrials.gov number, NCT00158431.)

RESUMO

BACKGROUND & AIMS: Activated granulocytes and monocytes/macrophages are implicated in the pathogenesis of ulcerative colitis. Open-label studies and clinical experience in Japan and Europe have suggested that granulocyte/monocyte apheresis is safe and effective in treating ulcerative colitis. METHODS: We evaluated the efficacy of granulocyte/monocyte apheresis in a randomized, double-blind, sham-controlled trial in patients with active moderate-to-severe ulcerative colitis (Mayo score 6-11) in community-based and tertiary care centers. As intervention, we used granulocyte/monocyte apheresis with the Adacolumn Apheresis System (JIMRO, Ltd, Takasaki, Japan) or sham apheresis in a 2:1 ratio for 9 weeks of treatment in a North American pivotal study (N = 168) and in a smaller, companion study of identical design conducted in Europe and Japan (N = 47). RESULTS: In the pivotal study, clinical remission rates (Mayo score 0-2, with scores of 0 on rectal bleeding and 0 or 1 on endoscopic examination) were 17% and 11% for the granulocyte/monocyte apheresis (n = 112)- and sham-treatment groups, respectively (n = 56; P = .361). Clinical response (Mayo score reduction of >/=3 points from baseline) was observed in 44% and 39% of patients, respectively (P = .620). Similar changes were observed for the apheresis- and sham-treatment groups for endoscopic remission and response, and changes in Mayo and quality-of-life scores. The companion study and pooled data from both studies also yielded similar results. CONCLUSIONS: In this study, granulocyte/monocyte apheresis was well tolerated but did not demonstrate efficacy for induction of clinical remission or response in patients with moderate-to-severe ulcerative colitis.

RESUMO

CONTEXT: Maintenance therapy for Crohn disease features the use of immunosuppressive drugs, which are associated with an increased risk of infection. Identification of safe and effective maintenance strategies is a priority. OBJECTIVE: To determine whether the oral administration of omega-3 free fatty acids is more effective than placebo for prevention of relapse of Crohn disease. DESIGN, SETTING, AND PATIENTS: Two randomized, double-blind, placebo-controlled studies (Epanova Program in Crohn's Study 1 [EPIC-1] and EPIC-2) conducted between January 2003 and February 2007 at 98 centers in Canada, Europe, Israel, and the United States. Data from 363 and 375 patients with quiescent Crohn disease were evaluated in EPIC-1 and EPIC-2, respectively. INTERVENTIONS: Patients with a Crohn's Disease Activity Index (CDAI) score of less than 150 were randomly assigned to receive either 4 g/d of omega-3 free fatty acids or placebo for up to 58 weeks. No other treatments for Crohn disease were permitted. MAIN OUTCOME MEASURE: Clinical relapse, as defined by a CDAI score of 150 points or greater and an increase of more than 70 points from the baseline value, or initiation of treatment for active Crohn disease. RESULTS: For EPIC-1, 188 patients were assigned to receive omega-3 free fatty acids and 186 patients to receive placebo. Corresponding numbers for EPIC-2 were 189 and 190 patients, respectively. The rate of relapse at 1 year in EPIC-1 was 31.6% in patients who received omega-3 free fatty acids and 35.7% in those who received placebo (hazard ratio, 0.82; 95% confidence interval, 0.51-1.19; P = .30). Corresponding values for EPIC-2 were 47.8% and 48.8% (hazard ratio, 0.90; 95% confidence interval, 0.67-1.21; P = .48). Serious adverse events were uncommon and mostly related to Crohn disease. CONCLUSION: In these trials, treatment with omega-3 free fatty acids was not effective for the prevention of relapse in Crohn disease. TRIAL REGISTRATION: clinicaltrials.gov Identifiers: EPIC-1: NCT00613197, EPIC-2: NCT00074542.

RESUMO

OBJECTIVES: To develop the 1996 MENQOL questionnaire further with advice regarding summary score computation, missing-data management, readability, recall period and assessment of the vasomotor domain reliability and construct validity. To develop a modified version, the MENQOL-Intervention questionnaire, for use where certain treatment side effects could negatively impact the quality of life. METHODS: MENQOL-Intervention modifications involved the addition of three items to the physical domain. For both questionnaires, psychometric property assessment was embedded in two randomized controlled trials of menopause interventions. Test-retest reliability and Cronbach's alpha were computed for all domains as was construct validity of the vasomotor domain for both questionnaires. RESULTS: The vasomotor intraclass correlation coefficient was 0.73 for the MENQOL-Intervention over 1 week and 0.78 for the MENQOL over 1 month. The altered physical domain of the MENQOL-Intervention questionnaire continued to show strong test-retest reliability and Cronbach's alpha consistent with the MENQOL. The MENQOL-Intervention demonstrated excellent face validity with high construct validity for the vasomotor domain of 0.78-0.80. For both instruments, comparisons of the vasomotor domains to hot flash scores, although statistically significant, were only moderate at 0.56 and 0.49. CONCLUSIONS: Both the MENQOL and the MENQOL-Intervention questionnaires show strong psychometric properties. We recommend using the MENQOL-Intervention questionnaire where intervention side effects might negatively impact a woman's quality of life. For both questionnaires, a summary score can be calculated.

RESUMO

BACKGROUND: Notwithstanding improving rates of hypertension control in North America, management of patients with both hypertension and dyslipidemia remains problematic. Based on evidence of improved control utilizing a simplified algorithm for management of hypertension (STITCH), we questioned whether a simplified comprehensive treatment algorithm featuring initial use of single-pill combinations (SPCs) would improve management of participants with both hypertension and dyslipidemia. METHOD: We randomized 35 primary care practices in Ontario to either Guidelines-care (following current Canadian guidelines) or STITCH2-care (following a treatment algorithm featuring SPCs). Practices each enrolled up to 50 participants with at least one risk factor above target at entry based on Canadian guidelines for BP and LDL-cholesterol control. The primary endpoint was achieving targets for both hypertension and dyslipidemia control after 6 months, assessed at the practice level. RESULTS: The primary endpoint was achieved in 31.3% of participants in STITCH2-care practices, compared with 28.1% in Guidelines-care practices, yielding a difference of 3.2% (P = 0.63). Notably, STITCH2-care practices had a significantly greater reduction in SBP while LDL-cholesterol reduction was only marginally greater in STITCH2 practices. CONCLUSION: The STITCH2 algorithm resulted in significantly greater use of any SPC compared with Guidelines-care and greater use of the SPC of calcium channel blocker/statin. Unwillingness of the prescribing physician to advance treatment beyond a monotherapy threshold was found to be an important determinant for failing to achieve blood pressure control. In contrast, the more important determinant for failing to achieve LDL control appeared to be the unwillingness of the prescribing physician to initiate therapy with a statin.

RESUMO

Despite improvements in blood pressure (BP) control, a substantial percentage of patients do not achieve target. The relative importance of determinants of poor BP control is unclear. Therefore, the authors conducted a post hoc exploratory analysis to assess determinants of BP control. Data were collected in 45 general practices, which enrolled patients with uncontrolled hypertension. Antihypertensive medication changes throughout the 6-month follow-up period were documented. Baseline and 6-month BPs were recorded. Of the 2030 patients analyzed, 320 had diabetes. Overall, 42% of patients did not achieve BP control. In multivariate analysis, failure to intensify therapy was identified as a significant independent predictor of lesser BP reduction. Of patients unable to reach target after 6 months, only 25% were prescribed ≥ 3 drugs. Patients with diabetes were significantly less likely to reach target than those without (26% vs 64%, P<.001). Antihypertensive therapy prescribed to patients with diabetes was only marginally more intensive than to those without. In patients with hypertension, whether with or without coexisting diabetes, poor BP control appears to be at least partially due to failure to uptitrate antihypertensive therapy. Clinical inertia is likely an important barrier to BP control.

RESUMO

BACKGROUND: Fatigue is a distressing, complex, multidimensional sensation common in individuals with chronic obstructive pulmonary disease (COPD). While fatigue negatively impacts functional performance and quality of life, there has been little study of the fatigue that affects participants in pulmonary rehabilitation programs. The purpose of this study was to examine the emotional, behavioral, cognitive, and physical dimensions of fatigue and their relationships to dyspnea, mental health, sleep, and physiologic factors. PATIENTS AND METHODS: A convenience sample of 42 pulmonary rehabilitation participants with COPD completed self-report questionnaires which measured dimensions of fatigue using the Multidimensional Fatigue Inventory, anxiety and depression using the Hospital Anxiety and Depression Scale, and sleep quality using the Pittsburgh Sleep Quality Index. Data on other clinical variables were abstracted from pulmonary rehabilitation program health records. RESULTS: Almost all (95.3%) participants experienced high levels of physical fatigue. High levels of fatigue were also reported for the dimensions of reduced activity (88.1%), reduced motivation (83.3%), mental fatigue (69.9%), and general fatigue (54.5%). Close to half (42.9%) of participants reported symptoms of anxiety, while almost one quarter (21.4%) reported depressive symptoms. Age was related to the fatigue dimensions of reduced activity (ρ = 0.43, P < 0.01) and reduced motivation (ρ = 0.31, P < 0.05). Anxiety was related to reduced motivation (ρ = -0.47, P < 0.01). Fatigue was not associated with symptoms of depression, sleep quality, gender, supplemental oxygen use, smoking status, or Medical Research Council dyspnea scores. CONCLUSIONS: Fatigue (particularly the physical and reduced motivation dimensions of fatigue) was experienced by almost all participants with COPD attending this pulmonary rehabilitation program. Fatigue affected greater proportions of participants than either anxiety or depression. The high prevalence of fatigue may impact on enrolment, participation, and attrition in pulmonary rehabilitation programs. Further investigation of the nature, correlates, and impact of fatigue in this population is required.

RESUMO

Notwithstanding the availability of antihypertensive drugs and practice guidelines, blood pressure control remains suboptimal. The complexity of current treatment guidelines may contribute to this problem. To determine whether a simplified treatment algorithm is more effective than guideline-based management, we studied 45 family practices in southwestern Ontario, Canada, using a cluster randomization trial comparing the simplified treatment algorithm with the Canadian Hypertension Education Program guidelines. The simplified treatment algorithm consisted of the following: (1) initial therapy with a low-dose angiotensin-converting enzyme inhibitor/diuretic or angiotensin receptor blocker/diuretic combination; (2) up-titration of combination therapy to the highest dose; (3) addition of a calcium channel blocker and up-titration; and (4) addition of a non-first-line antihypertensive agent. The proportion of patients treated to target blood pressure (systolic blood pressure <140 mm Hg and diastolic blood pressure <90 mm Hg for patients without diabetes mellitus or systolic blood pressure <130 mm Hg and diastolic blood pressure <80 mm Hg for diabetic patients) at 6 months was analyzed at the practice level. The proportion of patients achieving target was significantly higher in the intervention group (64.7% versus 52.7%; absolute difference: 12.0%; 95% CI: 1.5% to 22.4%; P=0.026). Multivariate analysis of patient-level data showed that assignment to the intervention arm increased the chance of reaching the target by 20% (P=0.028), when adjusted for other covariates. In conclusion, the Simplified Treatment Intervention to Control Hypertension Study indicates that a simplified antihypertensive algorithm using initial low-dose fixed-dose combination therapy is superior to guideline-based practice for the management of hypertension.

RESUMO

BACKGROUND: The optimum strategy for reducing allogeneic blood transfusion in patients undergoing total hip joint arthroplasty (THJA) is unknown. STUDY DESIGN AND METHODS: The effectiveness of a comprehensive blood conservation algorithm (BCA) was evaluated by means of a cluster randomization trial. Thirty hospitals performing primary THJA were randomly assigned to implement the algorithm or to continue with usual care (UC). Subsequently, the institutional rate of allogeneic transfusion was determined for 60 consecutive patients who underwent surgery at each site. The BCA consisted of patient and provider education, hemoglobin-based recommendations for specific blood conservation strategies (recombinant human erythropoietin [rHuEPO] or autologous blood donation [ABD]) and transfusion guidelines. The main outcome measure was the institutional allogeneic transfusion rate. RESULTS: One hospital withdrew consent after randomization, resulting in 14 hospitals assigned to BCA and 15 to UC. In the BCA arm, the institutional rates of rHuEPO use and ABD participation were 20.1 and 27.1 percent compared to 0.6 and 25.8 percent, respectively, in the UC arm. The allogeneic transfusion rate was substantially reduced in hospitals assigned to the BCA group (p = 0.02; absolute risk reduction, 9.6% [26.1% UC vs. 16.5% BCA]). Multivariate analysis of patient-level data showed that assignment to the UC arm was an independent risk factor for allogeneic transfusion (p = 0.037; odds ratio, 1.8; 95% confidence interval, 1.0-3.1) when adjusted for other prognostic factors. No differences were observed in the use of autologous blood. CONCLUSION: A comprehensive approach to blood conservation was superior to UC for reducing allogeneic transfusion in patients undergoing THJA.

RESUMO

PURPOSE: To compare nurse staffing measures derived from two widely used data sources: the American Hospital Association (AHA) Annual Survey of Hospitals and the California Office for Statewide Health Planning and Development (OSHPD). DESIGN: Descriptive cross-sectional study with measures of nurse staffing level and skill mix constructed from each database for 372 nonfederal, acute care hospitals in California. METHODS: Discrepancies in nurse staffing estimates between the two databases were examined. Relationships of nurse staffing with risk-adjusted patient outcomes (decubitus ulcer, failure to rescue, and mortality) were assessed through multivariate analyses and compared for nursing measures derived from the two databases. FINDINGS: For small, rural, or nonteaching hospitals, AHA reported substantially higher registered nurse (RN) hours per patient day than did OSHPD. RN proportion among licensed nurses matched most closely in the two databases. RN hours per patient day derived from both databases showed significant inverse relationships with decubitus ulcer and mortality, and the association was stronger for the measure based on the OSHPD data. RN proportion derived from the OSHPD data was significantly associated with all three patient outcomes, but the AHA measure had a significant relationship only with decubitus ulcer. CONCLUSIONS: Compared with the AHA survey, the OSHPD data on hospital nurse staffing appear to be more complete and also were more closely associated with patient outcomes. Efforts to refine the AHA survey as a national database for nurse staffing will significantly enhance the capacity for monitoring nurse workforce and its effect on quality of care.

RESUMO

BACKGROUND: Use of blood conservation techniques in elective surgery reduces the risk of infection and transfusion reactions that result from using allogeneic blood products. We examined the transfusion practice and blood conservation strategies for elective orthopedic procedures in 19 Canadian hospitals. METHODS: We reviewed the medical records of patients who underwent total hip or knee joint arthroplasty between June 1998 and January 1999 in a convenience sample of 19 hospitals to determine the pre- and postoperative hemoglobin concentrations, concurrent medical conditions, participation status in an autologous blood donation program, use of other blood conservation techniques, and occurrence of allogeneic and autologous transfusions. Patients were considered eligible for autologous blood donation if they weighed at least 25 kg, were in good general health without major cardiac conditions and had a hemoglobin concentration of at least 110 g/L. RESULTS: We reviewed 4535 medical records. Of the 4422 patients whose eligibility status was known, 2561 (57.9%) were eligible to participate in an autologous blood donation program. Only 842 (18.6%) of the patients predonated blood. Patients who did not predonate blood were older (mean age 70.1 v. 63.8 years) and were more likely to have concomitant medical conditions (60.3% v. 37.9%) than those who did predonate. Overall, 30.6% (95% confidence interval [CI] 29.1%-32.1%) of the patients who did not predonate blood received allogeneic transfusions. For patients who predonated, the rate of allogeneic transfusion was 14.1% (95% CI 11.8%-16.5%). The frequency with which blood conservation techniques other than autologous blood donation were used was minimal (in 2.4% of all cases). INTERPRETATION: The use of blood conservation techniques among hospitals in Canada remains low. Only a minority of eligible patients participated in an autologous blood donation program.

BACKGROUND: Most patients undergoing allogeneic marrow transplantation (alloBMT) require transfusions of RBCs. A retrospective analysis was performed to evaluate the utilization and risk factors for RBC transfusions including age and sex of recipient, HLA matching between donor and recipient, disease status at time of BMT, the occurrence of GVHD, ABO blood group compatibility, the source of progenitor cells and the Hb level before BMT (PT-Hb). STUDY DESIGN AND METHODS: Data from 519 consecutive patients receiving transplants between January 1995 and March 2000 were reviewed. The number of RBC transfusions was determined for the following periods: 0 to 60, 61 to 120, and 121 to 180 days after BMT. RESULTS: The transfusion requirements were greatest during the first 60 days after BMT and decreased with time. The total number of units transfused to this cohort of patients was 5398, of which 3505 units were utilized within the first 2 months. The mean number +/- SD of units transfused per patient from 0 to 60 days was 6.8 +/- 6.4; 61 to 120 days, 3.2 +/- 5.5; and 121 to 180 days, 2.0 +/- 4.6. An increased transfusion requirement was associated with lower PT-Hb, major ABO mismatch between donor and recipient, BMT in patients with more advanced disease, use of unrelated donors, older age, and female sex by Spearman's correlation analysis. The source of progenitor cells and the development of GVHD did not influence transfusion requirements. Increased mortality during the 6-month period after transplant was associated with lower PT-Hb, use of unrelated donors, advanced disease status at BMT, and sex by Cox regression analysis. In a multivariate model, PT-Hb remained significant when controlling for the other risk factors. CONCLUSION: The PT-Hb was identified as an independent risk factor for RBC transfusions during alloBMT. As well, a lower PT-Hb was found to be an independent risk factor for increased mortality during the 6-month study period.

RESUMO

BACKGROUND & AIMS: Although antibiotics are frequently used to treat Crohn's disease, this practice is not supported by strong evidence from randomized trials. METHODS: We conducted a double-blind multicenter study of patients with active Crohn's disease of the ileum, right colon, or both. Patients were randomized to receive oral ciprofloxacin and metronidazole, both 500 mg twice daily, or placebo for 8 weeks. All patients received oral budesonide 9 mg once daily. The primary efficacy measure was the proportion of patients in remission at week 8. RESULTS: Of the 134 patients who were randomized, 130 were evaluated for efficacy; 66 received placebo, and 64 received antibiotics. At week 8, 21 patients (33%) assigned to antibiotics were in remission as compared with 25 patients (38%) in the placebo group (P = 0.55; absolute difference, -5%; 95% confidence interval, -21% to 11%). An interaction (P = 0.025) between treatment allocation and disease location on treatment response was identified. Among patients with disease of the colon, 9 of 17 (53%) were in remission after treatment with antibiotics, compared with 4 of 16 (25%) of those who received placebo (P = 0.10). Discontinuation of therapy because of adverse events occurred in 13 of 66 (20%) patients treated with antibiotics, compared with 0 of 68 in the group who received placebo (P < 0.001). CONCLUSIONS: In patients with active Crohn's disease of the ileum, the addition of ciprofloxacin and metronidazole to budesonide is an ineffective intervention, but this antibiotic combination may improve outcome when there is involvement of the colon.
