The quality of included studies was assessed, data were extracted, results were summarized qualitatively and using meta-analysis, and the strength of the evidence was graded for each primary outcome. There was insufficient evidence to draw conclusions for all other long-term primary outcomes including stroke, myocardial infarction, and congestive heart failure. Firm conclusions regarding health-related quality of life were not possible given heterogeneity across studies for instruments employed, measurement timing, and clinical characteristics. Exercise capacity and related outcomes from randomized controlled trials comparing radiofrequency ablation with medical therapy. Atrial fibrillation is characterized by uncoordinated atrial activation with resulting 4, 5 deterioration of atrial mechanical function. Typically, pharmacologic therapy is the primary treatment for rate and rhythm control, while pulmonary vein isolation with catheter ablation is reserved for second-line treatment but may be appropriate 5 as a first-line treatment in select populations when a rhythm control strategy is desired. Rhythm control should not be used to allow patients to come off anticoagulation as the decision regarding anticoagulation 5 should be based on their risks of thromboembolic events and bleeding. Selection of the first-line antiarrhythmic medication is largely driven by the presence or absence of structural heart disease. In patients with heart failure, the guidelines recommend one of two antiarrhythmic medications as 5 first-line therapy (dofetilide and amiodarone). Side effects can occur with the use of antiarrhythmic medications; some may actually cause more arrhythmias and some may lose effectiveness over time. Patients on these medications therefore need to be monitored to assess the impact of medications on heart rhythm and the potential for side effects and interactions with any concomitant medications such as anticoagulants. Relief of symptoms is a primary reason for considering catheter ablation as a treatment strategy. For the procedure to be successful, complete bi- directional electrical isolation of all pulmonary veins should be achieved. Recent systematic reviews attempted to 23-25 evaluate the efficacy of approaches relative to each other, but significant heterogeneity with 23 regard to the approaches compared precluded meaningful conclusions. The comparative effectiveness and harms of catheter ablation in the Medicare population (65 years of age or <65 years of age and permanently disabled) were not explored. The 2009 report did not compare cryoablation with medical therapy or compare catheter ablation energy sources with one another. Procedural volume was associated with probability of in-hospital death but not with overall risk of complications. An almost two-fold increase in the number of patients treated with catheter ablation was reported between 2003 and 2006 compared with the number treated between 1995 and 2002 based on a world-wide survey of electrophysiology 27 centers. Anecdotally, utilization has continued to increase in the Medicare and general populations. For purposes of this report, efficacy refers to the ability of a treatment to produce a desired effect under optimum controlled conditions, such as during a randomized controlled trial. Effectiveness refers to the effect of treatment in actual clinical practice as evaluated by observational studies or comparative pragmatic trials. The analytic framework (Figure A) shows the target population, interventions and outcomes that were examined. Comparisons of interest include: a) Catheter ablation compared with medical therapy b) Comparing ablation using different energy sources Key Question 2. Analytic framework for catheter ablation for atrial fibrillation *Patients with longstanding persistent atrial fibrillation, persistent atrial fibrillation, or paroxysmal atrial fibrillation (considered separately); includes general population and Medicare population. The Key Informant panel included experts in cardiology primarily (with specialties in electrophysiology, heart failure, and cardiovascular aging/cardiovascular disease in older adults) and internal medicine; representatives from relevant specialty societies; government representatives. Key Informant input during topic refinement confirmed that this was a logical approach. Reference lists of included articles and relevant review articles were inspected for relevant publications. All citations were reviewed independently by two individuals at both the title/abstract and full-text level and differences were resolved by consensus. For all Key Questions, the focus was on evidence from comparative studies with the least potential for bias. Comparative observational studies were required to have a minimum of 100 patients to be included. Registry and administrative data studies were considered if inclusion criteria were met. For Key Question 2, case series that were specifically designed to evaluate harms and/or adverse events following ablation, had a minimum of 1000 patients and at least 80 percent followup were included because all included comparative studies were relatively small in size. For all Key Questions, both long-term (>12 months) and short-term (12 months) outcomes were reported. The primary outcomes (see Rating the Body of Evidence below) were considered to be the most clinically important and were the focus of reporting, decisions for data pooling and determination of overall strength of evidence. Where applicable and where data were available, results from short-term (12 months) and long-term (>12 months) followup were described. Each full-text article was independently evaluated for final inclusion by two investigators. After data extraction, at least one other staff member and one study investigator each verified the accuracy and completeness of abstraction for each study included. Comparative observational studies were assessed for study design features and sources of potential bias. Two investigators independently assessed the quality of each study, and any discrepancies were resolved through discussion and consensus. Studies rated good are considered to have the least risk of bias and their results are considered valid. Studies rated fair are susceptible to some bias, though not enough to invalidate the results. The study may be missing information, making it difficult to assess limitations and potential problems. The fair-quality category is broad, and studies with this rating will vary in their strengths and weaknesses. They have a serious or fatal flaw in design, analysis, or reporting; large amounts of missing information; discrepancies in reporting; or serious problems in the delivery of the intervention. The results of these studies are least as likely to reflect flaws in the study design as the true difference between the compared interventions. Studies rated as being poor in quality a priori were not excluded, but considered to be less reliable than higher-quality studies when synthesizing the evidence, particularly if discrepancies between studies are present. Data Synthesis Meta-analysis was conducted in order to provide more precise estimates for outcomes when adequate data were reported. To determine the appropriateness of meta-analysis, clinical and methodological diversity and assessed statistical heterogeneity were considered.

Abnormality in the water barrier function and the water retention capability of the horny cell layer are considered as causing/exacerbating factors of atopic dermatitis. Accordingly, the incidence rate of atopic dermatitis could be decreased by mois- turizer application during the newborn period. If the bacterial count is larger, it is important to take a skin care regimen with consideration of the bacterial ora on the skin surface. Given that a moisturizer is known to exert a higher moisturizing effect when externally applied twice a day than when applied once a day, consid- eration should be given to the number of external applications. Therefore, physicians should instruct patients not to forget the external application of 8.

Eligible patients enrolled into this study had previous inadequate response to topical medication antibiotics sinus infection npr purchase cheap ceftin on line. Patients received 1) an initial dose of 400 mg dupilumab (two 200 mg injections) on day 1 2012 antimicrobial susceptibility testing standards buy ceftin, followed by 200 mg once every other week (Q2W) for patients with baseline weight of <60 kg or an initial dose of 600 mg dupilumab (two 300 mg injections) on day 1 antibiotics for dogs how long discount 250mg ceftin, followed by 300 mg Q2W for patients with baseline weight of 60 kg; 2) an initial dose of 600 mg dupilumab (two 300 mg injections) on day 1 antibiotic resistance coalition buy ceftin 500mg line, followed by 300 mg every 4 weeks (Q4W) regardless of baseline body weight; or 3) matching placebo. Clinical Response the efficacy results at week 16 for adolescent atopic dermatitis study are presented in Table 11. Efficacy data from this study suggests that clinical benefit provided at week 16 was sustained through week 52. Patients were enrolled without requiring a minimum baseline blood eosinophil or other type 2 inflammatory biomarker (e. Annualized rate of severe asthma exacerbation events during the 24-week placebo controlled treatment period was also determined. Results were evaluated in the overall population (unrestricted by minimum baseline eosinophils or other type 2 inflammatory biomarkers) and subgroups based on baseline blood eosinophils count. Patients were randomised to receive either 200 mg (N=631) or 300 mg (N=633) Dupixent every other week (or matching placebo for either 200 mg (N = 317) or 300 mg (N= 321) every other week) following an initial dose of 400 mg, 600 mg or placebo respectively. The primary endpoint was the percent reduction in oral corticosteroid dose assessed in the overall population, based on a comparison of the oral corticosteroid dose at weeks 20 to 24 that maintained asthma control with the previously optimized (at baseline) oral corticosteroid dose. The demographics and baseline characteristics of these 3 studies are provided in Table 12 below. All patients were on oral corticosteroids for at least 6 months prior to the study initiation. In this 24-week trial, asthma exacerbations (defined as a temporary increase in oral corticosteroid dose for at least 3 days) were reduced by 59% in subjects receiving dupilumab compared with those receiving placebo (annualized rate 0. Effects on lung function, on oral steroid and exacerbation reduction were similar irrespective of baseline levels of type 2 inflammatory biomarkers (e. Rescue with systemic corticosteroids or surgery was allowed during the studies at the investigators discretion. Nasal congestion was rated daily by the subjects on a 0 to 3 categorical severity scale (0=no symptoms; 1=mild symptoms; 2=moderate symptoms; 3=severe symptoms). The demographics and baseline characteristics of these 2 studies are provided in Table 19 below. In the post-treatment period when patients were off dupilumab, the treatment effect diminished over time (see Figure 7a). The mean individual annualised prescribed total dose of systemic corticosteroids (in mg) during the treatment period was 71% lower in the pooled dupilumab group compared with the pooled placebo group (60. Efficacy with respect to severe asthma exacerbations and lung function was observed in both adolescents and adults. For the 200 mg every other week dose, patients had a reduction in the rate of severe exacerbations that was consistent with adults. Safety and efficacy in paediatric patients (< 12 years of age) with severe asthma have not been established. The European Medicines Agency has deferred the obligation to submit the results of studies with dupilumab in one or more subset of the paediatric population in atopic dermatitis and asthma (see section 4. The European Medicines Agency has waived the obligation to submit the results of studies with dupilumab in all subsets of the paediatric population in the treatment of nasal polyposis (see section 4. Steady-state concentrations were achieved by week 16 following the administration of 600 mg starting dose and 300 mg dose every other week or 300 mg dose every other week without a loading dose. Biotransformation Specific metabolism studies were not conducted because dupilumab is a protein. Elimination 34 Dupilumab elimination is mediated by parallel linear and nonlinear pathways. Elderly Of the 1,472 patients with atopic dermatitis exposed to dupilumab in a phase 2 dose-ranging study or phase 3 placebo-controlled studies, a total of 67 were 65 years or older. However, there were only 61 patients over 65 years of age included in this analysis. Of the 1,977 patients with asthma exposed to dupilumab, a total of 240 patients were 65 years or older and 39 patients were 75 years or older. Hepatic impairment Dupilumab, as a monoclonal antibody, is not expected to undergo significant hepatic elimination. Renal impairment Dupilumab, as a monoclonal antibody, is not expected to undergo significant renal elimination. No clinical studies have been conducted to evaluate the effect of renal impairment on the pharmacokinetics of dupilumab. Body Weight Dupilumab trough concentrations were lower in subjects with higher body weight with no meaningful impact on efficacy. No age-related pharmacokinetic difference was observed in adolescent patients after correction for body weight.

Consideration should be given to discontinuing treatment in patients who have shown no response after 16 weeks of treatment for atopic dermatitis. Some patients with initial partial response may subsequently improve with continued treatment beyond 16 weeks. If dupilumab treatment interruption becomes necessary, patients can still be successfully re-treated. Very limited data are available in patients with severe renal impairment (see section 5. Hepatic impairment No data are available in patients with hepatic impairment (see section 5. Body weight No dose adjustment for body weight is recommended for patients with asthma 12 years of age and older or in adults with atopic dermatitis (see section 5. For patients 12 to 17 years of age with atopic dermatitis, the recommended every other week dose is 200 mg (<60 kg) or 300 mg (60 kg). Paediatric patients the safety and efficacy of dupilumab in children with atopic dermatitis below the age of 12 years have not been established (see section 5. Method of administration Subcutaneous use Dupilumab is administered by subcutaneous injection into the thigh or abdomen, except for the 5 cm around the navel. For the initial 400 mg dose, two 200 mg injections should be administered consecutively in different injection sites. Reduction in corticosteroid dose may be associated with systemic withdrawal symptoms and/or unmask conditions previously suppressed by systemic corticosteroid therapy. This should be taken into consideration to determine type 2 status in patients taking oral corticosteroids (see section 5. Very rare cases of serum sickness/serum sickness-like reactions have been reported in the atopic dermatitis development program following the administration of dupilumab. Eosinophilic conditions Cases of eosinophilic pneumonia and cases of vasculitis consistent with eosinophilic granulomatosis with polyangiitis have been reported with dupilumab in adult patients who participated in the asthma development program. Patients with pre-existing helminth infections should be treated before initiating dupilumab. Conjunctivitis related events Patients treated with dupilumab who develop conjunctivitis that does not resolve following standard treatment should undergo ophthalmological examination (section 4.
