Results of these studies have not yet been published in a phase 1/2 studies via a dose-escalation strategy. IVIG also inhibits leukocyte adhesion and activation (Figure unpublished observations, September 2013). Its role in SCD patients with acute VOC is being evaluated in Tinzaparin. Tinzaparin, a low-molecular-weight heparin, was studied in a randomized, double-blind clinical trial. Heparins act via inhibition of P-selectin–mediated adhesion35 and other anti- inﬂammatory effects36 in addition to their expected anticoagulant effect. After exclusion of patients with thrombocytopenia or CNS vasculopathy, 253 subjects were enrolled, 12 years of age and older, in a study in which reduced duration of VOC and no severe bleeding complications were reported. An oral P-selectin inhibitor with an order of magnitude greater potency than heparin demonstrated improved microvascular ﬂow in SCD patients in a phase 1 study, but has a very short half-life. Propranolol was administered to SCD patients in a phase 1 dose escalation study and signiﬁcantly reduced epinephrine- stimulated SS-RBC adhesion in a dose-dependent manner. These results imply that -blockers have a potential role as antiadhesive therapy via inhibition of Figure 2. Activating and inhibitory arms of neutrophil activation. A phase 2 study the up-regulation of the leukocyte integrin Mac-1 at the leading edge of of propranolol in SCD is currently open. GMI-1070 works principally by inhibiting E-selectin–mediated activation. Polarized expression of activated Mac-1 allows the capture of erythrocytes. IVIG administration works by binding Targeting inﬂammation to Fc RIII expressed on neutrophils, leading to the recruitment of SHP-1 Regadenoson. Regadenoson is an A2A receptor (A2AR) agonist that inhibits Mac-1 activation. Many important scientiﬁc and clinical contributions in SCD ing sites in the United States.

Patients were 18-75 years old and had poorly controlled asthma while taking ICS cheap vardenafil 20mg on-line impotence vasectomy. Subjects treated with BDP had greater improvement in symptoms than those treated with BUD (mean change from baseline in % of days without symptoms: wheeze 26 purchase genuine vardenafil on-line erectile dysfunction kidney failure. There was no significant difference in beta-agonist use (mean change from baseline % of days used; -23. Beclomethasone compared with ciclesonide We did not identify any good or fair quality systematic reviews or head-to-head trials that compared beclomethasone with ciclesonide. Beclomethasone compared with flunisolide We did not identify any good or fair quality systematic reviews or head-to-head trials that compared beclomethasone to flunisolide. Controller medications for asthma 30 of 369 Final Update 1 Report Drug Effectiveness Review Project 4. Beclomethasone compared with fluticasone Two systematic reviews and 11 head-to-head RCTs comparing fluticasone (FP) to BDP met our 23 inclusion criteria. One systematic review included studies comparing FP compared with BDP or BUD. Of the 71 studies included in this review, 33 compared FP to BDP (nine of those 33 were included in our review). Comparisons were stratified by FP:BDP/BUD dose ratios of 1:2 or 1:1. The pooled treatment effect of FP was compared to the pooled treatment effect for BDP and BUD. For the studies conducted at dose ratios of 1:2, pooled estimates indicate that FP-treated patients had fewer symptoms, required less rescue medication, and had a higher likelihood of pharyngitis (see Key Question 2) than those treated with BDP or BUD. For the studies conducted at dose ratios of 1:1, individual studies and pooled estimates suggest no difference in symptoms, rescue medicine use, or the number of asthma exacerbations. Although we rated the quality of this review as good, the comparison of fluticasone to the combined effect of beclomethasone and budesonide limits possible conclusions regarding the specific comparison of beclomethasone to fluticasone. The review included nine studies (1265 participants) and found no statistically significant difference between treatments for symptom scores and quality of life. The single good-rated trial compared BDP 400 mcg/day (MDI-HFA) to FP 400 mcg/day (MDI) in 172 adults with mild 33 to severe persistent asthma for 6 weeks; both were medium potency doses. The trial was conducted in 30 general practice sites in the United Kingdom and Ireland. There were no significant differences in the improvement of asthma symptoms, sleep disturbance, rescue medicine use, or quality of life (AQLQ mean change from baseline) between the two groups. One was conducted exclusively in a population of 31 children and adolescents aged 4-11 and one included children, adolescents, and young adults 34 aged 4-19. Asthma severity ranged from mild- to severe-persistent. Doses ranged from low to high; all studies included comparisons of equipotent doses of BDP and FP. All but two trials assessed asthma symptoms and rescue medicine use. The majority of trials reported no difference between BPD- and FP-treated patients for the outcomes of interest reported. Four studies found FP to be better than BDP for at least one 37 36 outcome: symptoms, nighttime symptoms, rescue medicine use—increase in percent of 34 37 32 rescue free days or mean change in rescue puffs per day, or exacerbations. One study found 36 BDP-treated patients to have lower daytime symptom scores. Beclomethasone compared with mometasone 38, 39 Two fair-quality RCTs compared treatment with BDP and mometasone for 12 weeks. Both compared medium-dose BDP MDI (336 mcg/d), multiple doses of mometasone DPI (low-dose 38 200 mcg/d and medium-dose 400 mcg/d in both studies, and high-dose 800 mcg/d in only one), and placebo in patients at least 12 years old with persistent asthma. Both studies found no statistically significant differences between BDP and mometasone for symptoms, nocturnal awakenings, and rescue medicine use. Controller medications for asthma 31 of 369 Final Update 1 Report Drug Effectiveness Review Project 6. Beclomethasone compared with triamcinolone 40, 41 We found two fair-quality multicenter RCTs comparing BDP to triamcinolone (TAA). Both compared medium-dose BDP (336 mcg/d), medium-dose TAA (800 mcg/d), and placebo for eight weeks in adult subjects. Both found no difference between the active treatment groups for 41 rescue medicine use and one found no difference in nighttime awakenings. They reported conflicting results for improvement of symptoms: one reported greater improvement with BDP 41 40 than TAA and one reported no difference. Budesonide compared with ciclesonide Five fair-quality multicenter RCTs meeting our inclusion criteria compared BUD with 58-62 62 ciclesonide. One was conducted in children age 6-11 61 and one in adolescents 12-17 years old. One was conducted using subjects with mild to moderate persistent asthma, two with mild to severe, one with moderate to severe, and one with severe persistent asthma. Two trials only compared nonequivalent doses with ciclesonide given 58, 60 at a higher relative dose than BUD. The three studies comparing equivalent doses were non- inferiority trials. All studies used dry powder formulations of BUD and HFA-MDI for ciclesonide. All five trials evaluated outcomes for asthma symptoms and rescue medicine use 59 and all but one reported exacerbations. All five trials were funded by pharmaceutical companies. Overall, the evidence from the three studies comparing equivalent doses (low versus low or medium versus medium doses of ICSs) was consistent, finding ciclesonide to be non-inferior to 59, 61, 62 BUD. All three studies reported similar improvement in symptoms, rescue medication 59, 61, 62 61, 62 use, and quality of life for subjects treated with ciclesonide and those treated with BUD. Budesonide compared with flunisolide We found one fair-quality multicenter RCT comparing BUD (1200 mcg/d) to flunisolide (1500 42 mcg/d) in adults (N = 154) with moderate persistent asthma for 6 weeks. They reported no statistically significant differences between BUD and flunisolide in change from baseline in asthma symptoms, nocturnal awakenings, or rescue medicine use. Budesonide compared with fluticasone One previously described systematic review and eight head-to-head RCTs comparing FP to BUD 23 met our inclusion criteria. The systematic review included studies comparing FP with BDP or BUD. Of the 71 studies included in this review, 37 compared FP to BUD. Comparisons were stratified by FP: BDP/BUD dose ratios of 1:2 or 1:1. The pooled treatment effect of FP was compared to the pooled treatment effect for BDP and BUD. For the studies conducted at dose ratios of 1:2, pooled estimates indicate that FP-treated patients had fewer symptoms, required less rescue medication, and had a higher likelihood of pharyngitis (see Key Question 2) than those treated with BDP or BUD.
