Purpose
Acute myeloid leukemia (AML) disproportionately affects older adults; the prognosis in this subpopulation is generally poor, with variable use of inpatient chemotherapy. This study characterizes treatment patterns, hospitalizations, and outcomes among older patients with AML.Methods
Using the Centers for Medicare & Medicaid Services' 2010–2012 100% Limited Data Set (LDS), data from all hospital claims from fee-for-service Medicare beneficiaries between 60 and 75 years of age with newly diagnosed AML and ≥1 hospitalization were analyzed.Findings
Among 3700 identified patients with AML, 1979 (53.5%) received chemotherapy. Hospitalization rates were highest initially and then declined over time, irrespective of chemotherapy use. The mean length of initial hospital stay was longer in patients receiving chemotherapy. Intensive care unit admissions occurred in 33% of initial hospitalizations. Factors associated with receiving chemotherapy included younger age, fewer comorbidities, and the absence of prior hematologic disorders. Chemotherapy was associated with significantly increased survival compared with no chemotherapy (P < 0.0001).Implications
AML in older patients is associated with frequent hospitalizations and intensive care unit admissions. New treatment options with more favorable risk-to-benefit profiles are needed in this population. 相似文献2.

Purpose
The objective of the current analyses was to characterize the pharmacokinetic properties of atrasentan and the exposure-response relationships for the efficacy end point, urinary albumin to creatinine ratio (UACR), and the treatment-emergent adverse event, peripheral edema, during 8 or 12 weeks of treatment.Methods
Results from 3 Phase II, randomized, double-blind, placebo-controlled studies (N = 257) were used for the population pharmacokinetic and exposure-response models. Concentration-time and response data for efficacy and tolerability were analyzed using a nonlinear mixed-effects population analysis and logistic regression approaches.Findings
The pharmacokinetic data were adequately described by a 2-compartment model with first-order absorption and elimination. After weight was accounted for, no clinically meaningful differences were found in CL/F or Vd/F of the central compartment between Western and Japanese patients. Exposure-response analyses confirmed the efficacy of atrasentan in reducing UACR, with an estimated decrease in UACR of ≥37% when the atrasentan dose was 0.75 mg or higher. No significant association between atrasentan exposure and the rate of edema was identified at atrasentan doses of 0.5, 0.75, and 1.25 mg. The rates of peripheral edema were comparable in patients receiving active treatment and placebo.Implications
The exposure-response relationships for efficacy and tolerability were consistent between Western and Japanese patients. On the basis of these analyses, a dose of 0.75 mg/d was selected for the Phase III trial. ClinicalTrials.gov identifiers: NCT01356849, NCT01399580, and NCT01424319. 相似文献3.

Purpose
The aim of this study was to describe the treatment journey of patients with multiple sclerosis (MS).Methods
This study was conducted in 2 phases. The first consisted of a claims-based analysis of data from patients diagnosed with MS between October 1, 2010, and May 31, 2014. Study patients were aged ≥18 years, had ≥12 months of continuous eligibility before and after the earliest MS diagnosis (index date), ≥1 disease-modifying therapy (DMT) claim postindex, and no claims with a code for DMT or MS during the 12-month preindex period. The second phase consisted of medical record reviews in a subset of patients in the claims study who had ≥1 neurologist visit within 90 days of the index MS diagnosis.Findings
A total of 1639 patients were selected for claims-based analysis, and medical record analysis was conducted in a subset of 327 of those patients. The mean age in both samples was 42 years; females constituted about 70% of each group. Medical records showed that within a year of the first neurologist visit, 97.6% patients had a confirmed MS diagnosis; however, in 58.0%, MS type was not specified. MS symptoms were documented in less than half of all patients at the index neurologist visit. Early management consisted of magnetic resonance imaging (98.5% of patients), and the management of flares (annualized relapse rate, 0.3 [0.6] per patient). Use of spinal tap (21.7%), Expanded Disability Status Scale score (4.6%), and timed 25-foot walk score (8.6%) to evaluate disease progression was infrequent. The percentages of patients discontinuing the first DMT over time were high (43.1% among patients with 12–24 months of postindex follow-up, to 65.7% among patients with >36 months of postindex follow-up). Neurologists noted that about 10% of patients had difficulty adhering to an MS medication regimen, and documented several reasons for discontinuation, including adverse drug events and lack of desired effectiveness.Implications
In clinical practice, early MS treatment in DMT users is focused on symptom management, irrespective of MS type. Patients may benefit from initiating optimal treatment earlier. First-line therapy was often a transient option. 相似文献4.

Purpose
The aim of this study was to evaluate the efficacy and tolerability of rosuvastatin/ezetimibe combination therapy in Korean patients with high cardiovascular risk.Methods
This was a 12-week, randomized, double-blind, placebo-controlled, multicenter study. A total of 337 patients were screened. After a 4-week run-in period, 245 of these patients with high or moderately high risk as defined by the National Cholesterol Education Program Adult Treatment Panel III guidelines were randomly assigned. Patients received 1 of 6 regimens for 8 weeks as follows: (1) rosuvastatin 5 mg, (2) rosuvastatin 5 mg/ezetimibe 10 mg, (3) rosuvastatin 10 mg, (4) rosuvastatin 10 mg/ezetimibe 10 mg, (5) rosuvastatin 20 mg, or (6) rosuvastatin 20 mg/ezetimibe 10 mg. The primary outcome variable was percentage change in the level of LDL-C at week 8 of drug treatment. Secondary outcome variables included percentage changes of other lipid variables and achievement rates of LDL-C targets. Tolerability analyses were also performed.Findings
The percentage change of LDL-C ranged from –45% to –56% (mean, –51%) in the monotherapy groups and from –58% to –63% (mean, –60%) in the combination therapy groups. The percentage change was greater in the pooled combination therapy group than in the counterpart (P < 0.001 for the pooled groups); this difference was more obvious for regimens with a lower statin dose. The percentage reductions of total cholesterol and triglycerides were greater in the combination groups than in the monotherapy groups. The LDL-C target achievement rates were 64% to 87% (mean, 73%) in the monotherapy groups and 87% to 95% (mean, 91%) in the combination groups (P = 0.01 for the pooled groups). The rates were significantly greater in patients receiving the combination therapy than in the monotherapy at lower doses of rosuvastatin. The proportions of patients with various adverse events were not significantly different between the groups.Implications
Rosuvastatin/ezetimibe combination therapy has better efficacy and target achievement rates than rosuvastatin monotherapy in patients with high cardiovascular risk. 相似文献5.

Purpose
The purpose of this study was to examine the efficacy and safety of adding ω-3 fatty acids to rosuvastatin in patients with residual hypertriglyceridemia despite statin treatment.Methods
This study was a multicenter, randomized, double-blind, placebo-controlled study. After a 4-week run-in period of rosuvastatin treatment, the patients who had residual hypertriglyceridemia were randomized to receive rosuvastatin 20 mg/d plus ω-3 fatty acids 4 g/d (ROSUMEGA group) or rosuvastatin 20 mg/d (rosuvastatin group) with a 1:1 ratio and were prescribed each medication for 8 weeks.Findings
A total of 201 patients were analyzed (mean [SD] age, 58.1 [10.7] years; 62.7% male). After 8 weeks of treatment, the percentage change from baseline in triglycerides (TGs) and non–HDL-C was significantly greater in the ROSUMEGA group than in the rosuvastatin group (TGs: ?26.3% vs ?11.4%, P < 0.001; non–HDL-C: ?10.7% vs ?2.2%, P = 0.001). In the linear regression analysis, the lipid-lowering effect of ω-3 fatty acids was greater when baseline TG or non?HDL-C levels were high and body mass index was low. The incidence of adverse events was not significantly different between the 2 groups.Implications
In patients with residual hypertriglyceridemia despite statin treatment, a combination of ω-3 fatty acids and rosuvastatin produced a greater reduction of TGs and non?HDL-C than rosuvastatin alone. Further study is needed to determine whether the advantages of this lipid profile of ω-3 fatty acids actually leads to the prevention of cardiovascular event.

Purpose
This 8-week study in Korea aimed to evaluate the efficacy and tolerability of a telmisartan/amlodipine + hydrochlorothiazide (TAH) combination versus telmisartan/amlodipine (TA) combination in patients with essential hypertension that did not respond appropriately to 4-week treatment with TA.Methods
All patients who met the inclusion criteria received TA (40/5 mg) during a 4-week run-in period (period 1). Patients who met the criteria for essential hypertension (mean sitting systolic blood pressure [MSSBP], ≥140 and <200 mm Hg, or ≥130 and<200 mm Hg in those with diabetes mellitus or chronic kidney disease) after period 1 were randomly assigned to receive TA 40/5 mg + hydrochlorothiazide 12.5 mg (test group) or TA only (control group). The test and control drugs were administered in each group for 2 weeks (period 2). Patients who completed period 2 underwent 6-week treatment (period 3) with a TAH and TA dose twice that in period 2. The primary end point was the change in MSSBP at week 8 of treatment. Secondary end points were the change in MSSBP at week 2 and MS diastolic BP, BP control rate, and BP response rate at weeks 2 and 8. Treatment tolerability was assessed based on adverse events (AEs), laboratory evaluations (chemistry, hematology, and urinalysis), 12-lead ECG, and physical examination including vital sign measurements.Findings
We randomized 310 patients to the treatment groups. The mean (SD) ages of the TAH and TA groups were 62.0 (10.8) and 63.4 (10.4) years, respectively. The least squares mean change in MSSBP was significantly greater in the TAH group than in the TA group after 8 weeks (–18.7 vs –12.2 mm Hg; P < 0.001). Similar results were obtained on changes in MSSBP after 2 weeks and changes in sitting diastolic BP, BP control rate, and BP response rate at weeks 2 and 8 compared with the respective baseline values. The prevalences of treatment-emergent AEs (29.0% vs 16.3%; P = 0.008) and adverse drug reactions (20.0% vs 10.5%; P = 0.020) were significantly greater in the TAH group than in the TA group. Most treatment-emergent AEs were mild or moderate; none were severe. The most frequently reported AEs were dizziness and headache.Implication
TAH triple therapy was more effective than was TA double therapy in reducing BP in these patients in Korea with essential hypertension that did not adequately respond to TA. ClinicalTrials.gov identifier: NCT02738632. 相似文献8.

Purpose
The purpose of this study was to compare the adherence of the glimepiride/metformin sustained release (GM-SR) once-daily fixed-dose combination and glimepiride/metformin immediate release (GM-IR) BID fixed-dose combination in type 2 diabetes therapies.Methods
An open-label, randomized, multicenter, parallel-group study was conducted at 11 hospitals in the Republic of Korea. A total of 168 patients with type 2 diabetes treated with >4 mg of glimepiride and 1000 mg of metformin by using free or fixed-dose combination therapy for at least 2 weeks were enrolled. Patients were randomized to receive GM-SR 4/1000 mg once-daily or GM-IR 2/500 mg BID for 24 weeks. Adherence was compared by using the Medication Event Monitoring System (MEMS).Findings
A significant difference in adherence was observed between the 2 groups. Overall adherence, defined by the number of container openings divided by the number of prescribed doses, was 91.7% in the GM-SR group and 88.6% in the GM-IR group (P < 0.001). The percentage of treatment days with the correct number of doses taken was 85.3% in the GM-SR group and 75.1% in the GM-IR group (P < 0.001). The percentage of missed doses was 11.7% in the GM-SR group and 15.3% in the GM-IR group (P < 0.001). The percentage of doses taken in the correct time window and therapeutic coverage were higher in the GM-SR group (P < 0.001). There was no significant difference in glycosylated hemoglobin changes or number of adverse events between the 2 groups. A total of 168 patients randomized to receive GM-SR once daily (86 patients) or GM-IR twice daily (82 patients). Mean Age were 57.8 ± 9.6 years old. Male : female ratio was 47.6 : 52.4 %. Body mass index were 66.3 ± 12.0 kg/m2, Diabetes duration were 10.5 ± 6.6 years.Implications
This study showed that patient adherence with GM-SR once daily was significantly better than with GM-IR BID. ClinicalTrials.gov identifier: NCT01620489. 相似文献9.

Purpose
Chronic obstructive pulmonary disease (COPD) is a progressive disease that impairs both objectively measured lung function and patient-reported health status. In a randomized clinical trial of patients with moderate to severe COPD, we compared changes in health status after adding arformoterol tartrate or placebo to patients’ treatment regimens.Methods
In this multicenter, double-blind trial, patients were randomized to receive nebulized arformoterol 15 µg BID (n = 420) or matched placebo (n = 421). Treatment with other COPD medications was permitted, except for long-acting β2-agonists. Inclusion criteria were a forced expiratory volume in 1 second (FEV1) ≤65% of predicted, FEV1 >0.50 L, age ≥40 years, smoking history ≥15 pack-years, and a baseline breathlessness severity grade ≥2. The Clinical COPD Questionnaire (CCQ) was used to measure health status at randomization and at months 3, 6, and 12. CCQ scores range from 0 to 6, with higher scores indicating worse health status, and a decrease from baseline in total score by 0.4 point is considered clinically significant. Outcomes were analyzed by using mixed models for repeated measures.Findings
At baseline, patients’ mean age was 63.8 years; 42.9% of patients were female, and 51.4% were current smokers. The mean baseline CCQ total scores were 2.88 and 2.91 for the arformoterol and placebo groups, respectively. A total of 841 patients were randomized to receive either arformoterol (n = 420) or placebo (n = 421); among them, 211 (50.1%) who received placebo and 255 (60.7%) who received arformoterol completed the trial. Arformoterol-treated patients had greater mean improvement from baseline in CCQ total score (?0.18 vs 0.02; P = 0.001), symptoms (?0.21 vs 0.01; P = 0.002), functional state (?0.15 vs 0.02; P = 0.018), and mental state (?0.18 vs 0.02; P = 0.023) than patients receiving placebo. At study end, 38.3% of the arformoterol-treated patients and 30.8% of patients receiving placebo reported clinically significant improvements on the CCQ (P = 0.026). These improvements were only modestly correlated with improvements in FEV1 (r = ?0.15; P < 0.01).Implications
In this 52-week trial, arformoterol-treated patients had greater improvements in health status than patients receiving placebo. Assessing health status along with lung function seems to provide additional information regarding the effectiveness of COPD maintenance treatments.

Purpose
We designed a prospective, multicenter, randomized, controlled study to assess a 5-month regimen compared with the standard regimen on previously treated patients with pulmonary tuberculosis (TB).Methods
We enrolled 917 sputum smear–positive patients undergoing additional treatment in 27 major tuberculosis hospitals in China. Patients were randomly assigned to a test group (n = 626)treated with a 5-month regimen of moxifloxacin, pasiniazid, rifabutin, ethambutol, and pyrazinamide or a reference group (n = 291) treated with an 8-month regimen of isoniazid, rifampicin, and streptomycin. All patients with a favorable response were followed up for 5 years after the end of treatment.Findings
Of the study patients, 61 in the test group and 19 in the reference group had multidrug-resistant (MDR) TB. The treatment success rate in the study group was 74.12%, which was significantly higher than the 67.70% in the reference group (P = 0.04), whereas the treatment success rate of patients with MDR-TB was not significantly different between the test and reference groups (70.5% vs 63.1%, P =0.79). The adverse effects rates in the test and reference groups were 7.4% and 3.1%, respectively (P = .01). The difference in the TB recurrence rates between the group arm (9.6%) and the reference group (21.8%) was statistically significant (P < 0.001).Implications
The moxifloxacin, pasiniazid, rifabutin, ethambutol, and pyrazinamide test regimen yielded higher success and lower recurrence rates than the currently recommended isoniazid, rifampicin, and streptomycin regimen, but the rate of adverse effects was higher.

Purpose
Combination therapy with ezetimibe and statins is recommended in cases of statin intolerance or insufficiency. The objective of this study was to compare the efficacy and safety of combination therapy with ezetimibe and rosuvastatin versus those of rosuvastatin monotherapy in patients with hypercholesterolemia.Methods
I-ROSETTE (Ildong ROSuvastatin & ezETimibe for hypercholesTElolemia) was an 8-week, double-blind, multicenter, Phase III randomized controlled trial conducted at 20 hospitals in the Republic of Korea. Patients with hypercholesterolemia who required medical treatment according to National Cholesterol Education Program Adult Treatment Panel III guidelines were eligible for participation in the study. Patients were randomly assigned to receive ezetimibe 10 mg/rosuvastatin 20 mg, ezetimibe 10 mg/rosuvastatin 10 mg, ezetimibe 10 mg/rosuvastatin 5 mg, rosuvastatin 20 mg, rosuvastatin 10 mg, or rosuvastatin 5 mg in a 1:1:1:1:1:1 ratio. The primary end point was the difference in the mean percent change from baseline in LDL-C level after 8 weeks of treatment between the ezetimibe/rosuvastatin and rosuvastatin treatment groups. All patients were assessed for adverse events (AEs), clinical laboratory data, and vital signs.Findings
Of 396 patients, 389 with efficacy data were analyzed. Baseline characteristics among 6 groups were similar. After 8 weeks of double-blind treatment, the percent changes in adjusted mean LDL-C levels at week 8 compared with baseline values were –57.0% (2.1%) and –44.4% (2.1%) in the total ezetimibe/rosuvastatin and total rosuvastatin groups, respectively (P < 0.001). The LDL-C–lowering efficacy of each of the ezetimibe/rosuvastatin combinations was superior to that of each of the respective doses of rosuvastatin. The mean percent change in LDL-C level in all ezetimibe/rosuvastatin combination groups was >50%. The number of patients who achieved target LDL-C levels at week 8 was significantly greater in the ezetimibe/rosuvastatin group (180 [92.3%] of 195 patients) than in the rosuvastatin monotherapy group (155 [79.9%] of 194 patients) (P < 0.001). There were no significant differences in the incidence of overall AEs, adverse drug reactions, and serious AEs; laboratory findings, including liver function test results and creatinine kinase levels, were comparable between groups.Implications
Fixed-dose combinations of ezetimibe/rosuvastatin significantly improved lipid profiles in patients with hypercholesterolemia compared with rosuvastatin monotherapy. All groups treated with rosuvastatin and ezetimibe reported a decrease in mean LDL-C level >50%. The safety and tolerability of ezetimibe/rosuvastatin therapy were comparable with those of rosuvastatin monotherapy. ClinicalTrials.gov identifier: NCT02749994. 相似文献12.
Purpose
Techniques used to identify AmpC β-lactamases in SPICE (Serratia, Pseudomonas, indole-positive Proteus, Citrobacter, and Enterobacter) organisms are not yet optimized for the clinical laboratory and are not routinely used. Clinicians are often left with an uncertainty on the choice of antibiotic when a SPICE organism is isolated. The purpose of this study was to evaluate the outcomes of carbapenem versus noncarbapenem regimens in treating bacteremia or urinary tract infection from a SPICE organism in clinical practice.Methods
This single-center, retrospective, cohort study analyzed data from adult patients who had clinical infection with a SPICE organism isolated from blood or urine cultures. Patients were assigned to a carbapenem- or noncarbapenem-treated group. The primary end point was clinical response, defined as a resolution of signs and symptoms of infection at the end of therapy.Findings
A total of 332 patients were assessed, and 145 patients met the inclusion criteria for the study. There were 20 patients who received a carbapenem, while 125 received a noncarbapenem regimen. The percentage of patients who were bacteremic was 46.2%. Clinical response overall was achieved in 80% of patients on a carbapenem versus 90.3% of patients on a noncarbapenem regimen (P = 0.24). The rate of microbiologic cure was 90% in patients on a carbapenem versus 91.2% in patients on a noncarbapenem regimen (P = 1).Implications
In this study in patients treated for infection with a SPICE organism in clinical practice, the rates of clinical response did not differ significantly between the carbapenem and noncarbapenem groups. Current CLSI breakpoints set for SPICE organisms may still be reliable and may not require additional testing for AmpC β-lactamases. 相似文献13.

Purpose
Fixed-combination drug products (FCDPs) combining dapagliflozin and metformin extended release (XR) may provide patients with type 2 diabetes mellitus with an alternative antihyperglycemic treatment, which could improve adherence by reducing tablet burden. This study evaluated the bioequivalence of dapagliflozin/metformin XR FCDP versus the co-administration of the individual monotherapy tablets currently available for use in the Russian Federation.Methods
Healthy subjects aged 18 to 45 years were enrolled in this randomized, open-label, 2-period crossover study, conducted in a single Russian center. Pharmacokinetic parameters (AUC0–t, Cmax, and Cmax/AUC0–t) were used to assess bioequivalence of dapagliflozin/metformin XR (10/1000 mg) FCDP to the individual component tablets (dapagliflozin [10 mg] plus metformin XR [2 × 500 mg]) under standard fed conditions. Safety and tolerability were also assessed.Findings
Forty healthy subjects were included (47.5% male; mean age, 30 years; and mean body mass index, 24.2 kg/m2). Dapagliflozin and metformin XR in the FCDP were bioequivalent to the individual component tablets marketed in the Russian Federation, with the 90% CIs of the geometric least-squares mean ratios for all key pharmacokinetic parameters being contained within the 80% to 125% bioequivalence limits. Both FCDP and the individual component formulations were well tolerated, with no serious adverse events.Implications
Bioequivalence of dapagliflozin/metformin XR FCDP and the individual components was established without any new safety concerns, presenting a safe alternative for patients currently receiving regimens including each component individually. ClinicalTrials.gov identifier: NCT02722239. 相似文献15.

Purpose
The aim of this study was to assess the clinical characteristics and trends in valganciclovir use among infants diagnosed with congenital cytomegalovirus (CMV) disease in the United States.Methods
We analyzed data from medical claims dated 2009–2015 from the Truven Health MarketScan® Commercial Claims and Encounters and Medicaid databases. We identified infants with a live birth code in the first claim who were continuously enrolled for at least 45 days. Among infants diagnosed with congenital CMV disease, identified by an ICD-9-CM or ICD-10-CM code for congenital CMV infection or CMV disease within 45 days of birth, we assessed data from claims containing codes for any CMV-associated clinical condition within the same period, and data from claims for hearing loss and/or valganciclovir within the first 180 days of life.Findings
In the commercial and Medicaid databases, we identified 257 (2.5/10,000) and 445 (3.3/10,000) infants, respectively, diagnosed with congenital CMV disease, among whom 135 (53%) and 282 (63%) had ≥1 CMV-associated condition, 30 (12%) and 32 (7%) had hearing loss, and 41 (16%) and 78 (18%) had a claim for valganciclovir. Among infants with congenital CMV disease who had a claim for valganciclovir, 37 (90%) among commercially insured infants and 68 (87%) among Medicaid-insured infants had ≥1 CMV-associated condition and/or hearing loss. From 2009 to 2015, the percentages with a claim for valganciclovir increased from 0% to 29% among commercially insured infants and from 4% to 37% among Medicaid-insured infants (P < 0.0001).Implications
During 2009–2015, there was a strong upward trend in valganciclovir claims among insured infants who were diagnosed with congenital CMV disease, the majority of whom had CMV-associated conditions and/or hearing loss. 相似文献16.

Purpose
Invasive aspergillosis (IA) remains a critical issue in immunosuppressed patients. Detection of galactomannan antigen (GM) in serum samples is included as a criterion of IA by the European Organization for the Research and Treatment of Cancer/Mycoses Study Group. Nevertheless, Aspergillus DNA detection by polymerase chain reaction (PCR) has not yet been included because clinical data validation is lacking. The present study describes the simultaneous performance of GM and PCR tests as routine methods for IA diagnosis.Methods
During the period January 2012 to December 2017, a total of 156 white children hospitalized in a tertiary children’s hospital of Athens (97 boys and 59 girls; age range, 5 months–14 years) were examined as possible cases of IA. Patients were classified into 4 groups based on their underlying diseases: hematologic malignancies (107 of 156 [68.6%]), solid tumors (16 of 156 [10.2%]), primary immunodeficiency (12 of 156 [7.7%]), and hereditary immunodeficiency (21 of 156 [13.5%]). GM detection was made with the Platelia Aspergillus Ag kit (Bio-Rad Laboratories, Hercules, California). Sera with a cut-off index ≥0.5 on at least 2 separate blood collections were considered positive. Serum detection of Aspergillus DNA was conducted with real-time PCR MycAssay Aspergillus assay (Myconostica Ltd, Cambridge, United Kingdom). PCR positivity was determined by using a threshold of 38 cycles in at least 1 serum sample. Four or more successive samples per patient were tested.Findings
Overall, 28 of 156 patients (53 of 744 serum samples) were found positive. Eleven patients were positive using both methods (24 samples). Four children were positive only by PCR (6 samples), whereas 13 (23 samples) were positive only with GM in consecutive samples. Agreement of both methods, GM(+)/PCR(+) or GM(–)/PCR(–), was found in 139 patients (90% of total patients) and 715 samples (96.1% of total samples). The agreement of both methods was found: (1) 85% in patients with hematologic malignancies; (2) 100% in patients with solid tumors; (3) 97.5% in patients with primary immunodeficiency; and (4) 98.8% in patients with hereditary immunodeficiency. Overall disagreement was observed in 17 patients, in which the positive result in any of the 2 methods was estimated as true positive in conjunction with radiologic and other clinical findings.Implications
The combination of GM and PCR, provided high diagnostic accuracy in consecutive samples (twice a week). Clinical, radiologic, and other laboratory findings should be taken into consideration in the evaluation of GM and PCR. 相似文献17.

Purpose
Triamcinolone hexacetonide (TH), triamcinolone acetonide (TA), and methylprednisolone acetate (MPA) are commonly used intra-articular steroid preparations. Studies suggest that intra-articular TH is more efficacious than MPA and TA in chronic inflammatory arthritis. However, it is unclear which of the latter two preparations has better efficacy. Thus, we compared intra-articular knee injections of MPA and TA in patients with chronic inflammatory arthritis.Methods
This double-blind, randomized controlled trial included patients with rheumatoid arthritis or spondyloarthritis with an acutely swollen knee joint (≥1 week, <24 weeks). They were randomly assigned (1:1) to intra-articular knee injection with MPA or TA (80 mg, 2 mL of each). Evaluations were performed at 4, 12, and 24 weeks. Primary outcome was time to relapse (Kaplan-Meier) over 24 weeks, with relapse defined as return to baseline pain or swelling ≥1 week. Secondary outcomes were change in pain and swelling (using a numerical rating scale), range of movement, and occurrence of adverse effects. Primary analysis was intention to treat, with last observation carried forward.Findings
One hundred patients (89 with rheumatoid arthritis) were randomly assigned in equal numbers to the MPA and TA groups. Nine patients relapsed in each group over 24 weeks. The mean time to relapse was not significantly different between the MPA and TA groups (20.8 [95% CI, 18.8–22.7] weeks and 20.9 [95% CI, 19.0–22.8] weeks, respectively; P = 0.9; hazard ratio = 1.0 [95% CI, 0.4–2.5]). In both groups, there was a significant decline in pain and swelling scores at all visits (P < 0.001); however, there were no significant intergroup differences. At 24 weeks, mean change in pain in the MPA (–4.4 [3.1]) and TA groups (–3.9 [2.8]) was not significantly different (P = 0.46). No infection, hematoma or hypopigmentation occurred in any patient. In addition, no significant intergroup differences were found in joint swelling, range of movement, modified (28 joint) Disease Activity Score using 3 variables, or Health Assessment Questionnaire over 24 weeks.Implications
No significant differences were found in efficacy between intra-articular knee injections with MPA and TA in these patients with chronic inflammatory arthritis. However, results need to be extrapolated cautiously because of the small sample size. Three-quarters of the patients remained relapse free at 24 weeks.

Purpose
Coronary microvascular dysfunction (CMD) is a common but underdiagnosed cause of chest pain. Literature is scant regarding effective treatments. We explored the effect of ranolazine on coronary flow reserve (CFR) among symptomatic patients with CMD.Methods
This pilot double-blinded randomized controlled trial included emergency department patients with chest pain and CMD admitted to an observation unit between June 2014 and November 2015. Participants were assessed by cardiac Rb-82 positron emission tomography and computed tomography imaging at baseline and 30 days. CMD was defined as CFR <2 corrected for rate pressure product or <2.5 uncorrected, with no evidence of obstructive or nonobstructive coronary artery disease or calcification. Patients with infarction, hypertensive urgency, heart failure, or prescribed QTc-prolonging drugs were excluded. Participants were assigned to ranolazine or placebo in a 2:1 ratio. Primary outcome was change in CFR at 30 days.Findings
We enrolled 31 patients (71% female, mean [SD] age 50 [6] years) with CMD (mean [SD] corrected CFR 1.6 [0.3]). Ranolazine improved CFR at 30 days by 17% (P = 0.005) compared with 0% with placebo (P = 0.67). However, there was no significant difference in the primary outcome as measured by mean change in CFR (0.27 ranolazine compared with 0.06 placebo; 95% CI, ?0.08 to 0.62).Implications
The emergency department offers a unique venue to diagnose CMD with acute symptoms. In an exploratory randomized controlled trial of symptomatic patients with CMD and no coronary artery disease, promising results were seem with ranolazine and CFR improving at 30 days. Large robust clinical trials are needed to verify improvement of CMD in a sex-specific model. ClinicalTrials.gov identifier NCT02052011. 相似文献20.
