Primary care referral patterns for patients with asthma: analysis of real-world data.

OBJECTIVE: To identify features related to management of patients prior to referral from primary care physicians (PCPs) to pulmonologists and allergists. METHODS: This is an analysis of patient claims data from Symphony Health (2013-2018). To characterize referrals, a longitudinal cohort included 12 months with no asthma claims prior to the index date, followed by 36 months of observation. We also assessed a cross-sectional cohort for 12 months at the end of the observational period to characterize disease control and treatment patterns. Referral was defined as the first appearance of a claim from an allergist or pulmonologist for a patient's initial visit for asthma. Descriptive statistics were used to analyze the data. RESULTS: The majority of patients with asthma were managed by PCPs (60%), followed by pulmonologists (16%) and allergists (8%). Forty-three percent had uncontrolled asthma. Only 8% were referred to specialists within the first 24 months after initial diagnosis, of which 76% were seen by pulmonologists and 24% by allergists. Referrals resulted in treatment change in 55%-68% of the cases. Patients who received a referral were more likely to be on oral corticosteroids (OCS) and/or have more hospitalizations/ED visits. CONCLUSIONS: About one-third of the patients managed by PCPs received intermittent and/or chronic OCS prior to referral, which may be an indication of uncontrolled disease. The referral patterns in this analysis illustrate underutilization of specialists in the consultation and management of patients with uncontrolled asthma.

Synthesis of a New Co Metal-Organic Framework Assembled from 5,10,15,20-Tetrakis((pyridin-4-yl) phenyl)porphyrin "Co-MTPhPyP" and Its Application to the Removal of Heavy Metal Ions.

The synthesis of a Co metal-organic framework assembled from 5,10,15,20-tetrakis((pyridin-4-yl)phenyl)porphyrin; TPhPyP) "Co-MTPhPyP" is reported. The TPhPyP ligand was synthesized via aldehyde condensation in 28% yield and characterized by 1H nuclear magnetic resonance (1H NMR), Fourier-transform infrared (FTIR), high-resolution mass spectrometry (HRMS), and UV-visible spectroscopy (UV-vis). Co-MTPhPyP was prepared by the solvothermal method from TPhPyP and CoCl2·H2O in 55% yield and characterized by X-ray powder diffraction (XRD), FTIR, thermogravimetric analysis (TGA), field-emission scanning electron microscopy with energy-dispersive X-ray (FESEM-EDS), X-ray photoelectron spectroscopy (XPS), and dynamic light scattering (DLS), showing a particle size distribution of 418 ± 58 nm. The sorption properties of the Co-MTPhPyP for the effective removal of Pb(II) and Cu(II) were evaluated in an aqueous medium and Cthe results showed uptake capacities of 383.4 and 168 mg of the metal g-1 after 2 h, respectively. Kinetic studies of Pb(II) adsorption by Co-MTPhPyP were adjusted to the pseudo-second-order model with a maximum adsorption capacity of 458.8 mg g-1 at 30 min of exposition.

Rhinovirus and asthma: Challenges and opportunities.

Human rhinoviruses (RVs) are the primary aetiological agent of the common cold. Generally, the associated infection is mild and self-limiting, but may also be associated with bronchiolitis in infants, pneumonia in the immunocompromised and exacerbation in patients with pulmonary conditions such as asthma or chronic obstructive pulmonary disease. Viral infection accounts for as many as two thirds of asthma exacerbations in children and more than half in adults. Allergy and asthma are major risk factors for more frequent and severe RV-related illnesses. The prevalence of RV-induced wheezing will likely continue to increase given that asthma affects a significant proportion of the population, with allergic asthma accounting for the majority. Several new respiratory viruses and their subgroups have been discovered, with various degrees of relevance. This review will focus on RV infection in the context of the epidemiologic evidence, genetic variability, pathobiology, clinical studies in the context of asthma, differences with other viruses including COVID-19 and current treatment interventions.

A phase 2 study to evaluate the safety, efficacy and pharmacokinetics of DP2 antagonist GB001 and to explore biomarkers of airway inflammation in mild-to-moderate asthma.

BACKGROUND: GB001 is an oral antagonist of the prostaglandin D2 receptor that may inhibit recruitment and activation of airway eosinophils, reducing airway inflammation. OBJECTIVE: To assess GB001 safety, efficacy and pharmacokinetics from a Phase 2 study and explore the association between type 2 biomarkers (fractional exhaled nitric oxide and blood eosinophils) and asthma control markers following GB001 administration. METHODS: A randomized, placebo-controlled, double-blind study evaluating 36 patients with mild-to-moderate atopic asthma. Patients receiving fluticasone propionate ≤500 mcg/day or equivalent were randomized (2:1) to GB001 (30 mg) or placebo once daily for 28 days. Safety, pharmacokinetics, forced expiratory volume in 1 second, asthma control questionnaire and rescue medication use were assessed. Clinical outcomes were analysed post hoc by baseline fractional exhaled nitric oxide (<35 and ≥35 ppb) and blood eosinophil (<250 and ≥250 cells/µL) subgroups. RESULTS: GB001 was well tolerated and rapidly absorbed with a 14.5-hour terminal half-life. Overall, GB001 demonstrated greater improvement relative to placebo in forced expiratory volume in 1 second at Day 28 (102 mL [95% CI: -110, 314]). Greater effects on forced expiratory volume in 1 second were observed in the high baseline fractional exhaled nitric oxide and blood eosinophil subgroups (207 mL [95% CI: -283, 698];133 mL [95% CI: -422, 687], respectively). These effects were observed as early as Day 2 (229 mL [95% CI: -170, 628]; 163 mL [95% CI: -223, 550] for the high baseline fractional exhaled nitric oxide and blood eosinophil subgroups, respectively) and were sustained through treatment completion. CONCLUSION AND CLINICAL RELEVANCE: GB001 was well tolerated, with the estimated half-life supporting once-daily (QD) dosing. GB001 may have a rapid and sustained effect on lung function, particularly in patients with type 2 phenotype. Further studies are needed to confirm these findings.

Impact of mepolizumab on exacerbations in severe asthma: Results from a U.S. insurance claims data base.

Background: In controlled clinical studies, mepolizumab has been shown to reduce exacerbation rates and the use of oral corticosteroids as well as improve asthma control and health-related quality of life compared with placebo in patients with severe eosinophilic asthma. However, real-world data on the impact of mepolizumab on clinical outcomes are limited. Objective: To evaluate the effect of mepolizumab on asthma exacerbations and asthma exacerbation-related costs in patients with severe asthma in U.S. clinical practice. Methods: This retrospective cohort study used U.S. administrative claims data from patients ages ≥12 years and with severe asthma at mepolizumab treatment initiation (index date; identification period, January 2015-June 2017) who had received two or more mepolizumab administrations within 180 days of the index date and had no evidence of treatment with another asthma biologic. The exacerbation rate and exacerbation-related costs were assessed in both the 12 months before mepolizumab initiation (baseline period) and the following 12 months (follow-up period). A clinical trial-like cohort was identified, defined as patients with two or more baseline exacerbations and ≥10 administrations during follow-up. Results: A total of 201 patients were included in the overall population and 74 patients in the clinical trial-like cohort. Mepolizumab significantly reduced the exacerbation rate between the baseline and follow-up periods in both the overall population and the clinical trial-like cohort (p < 0.001), which corresponded to 33.6% and 48.6% reductions, respectively. The rate of exacerbations in patients who required hospitalization between the baseline and follow-up periods was also reduced by 35.3% (p = 0.080) and 68.2% (p = 0.015) in the overall population and in the clinical trial-like cohort, respectively. Cost data were inconclusive. Conclusion: This study, which used real-world data, demonstrated that mepolizumab is associated with reductions in asthma exacerbations, in line with the findings from controlled clinical studies. These results provided further evidence of the effectiveness of mepolizumab in a real-world setting.

Assessment of the long-term safety of mepolizumab and durability of clinical response in patients with severe eosinophilic asthma.

BACKGROUND: Mepolizumab has demonstrated favorable safety and efficacy profiles in placebo-controlled trials of 12 months' duration or less; however, long-term data are lacking. OBJECTIVE: We sought to evaluate the long-term safety and efficacy of mepolizumab in patients with severe eosinophilic asthma (SEA). METHODS: COLUMBA (Open-label Long Term Extension Safety Study of Mepolizumab in Asthmatic Subjects, NCT01691859) was an open-label extension study in patients with SEA previously enrolled in DREAM (Dose Ranging Efficacy And Safety With Mepolizumab in Severe Asthma, NCT01000506). Patients received 100 mg of subcutaneous mepolizumab every 4 weeks plus standard of care until a protocol-defined stopping criterion was met. Safety end points included frequency of adverse events (AEs), serious AEs, and AEs of special interest. Efficacy end points included annualized exacerbation rates, changes from baseline in Asthma Control Questionnaire 5 scores, and blood eosinophil counts. Immunogenicity was also assessed. RESULTS: Overall, 347 patients were enrolled for an average of 3.5 years (maximum, 4.5 years; total exposure, 1201 patient-years). On-treatment AEs were reported in 94% of patients (exposure-adjusted rate, 3688 events/1000 patient-years). The most frequently reported on-treatment AEs were respiratory tract infection, headache, bronchitis, and asthma worsening. Seventy-nine (23%) patients experienced 1 or more on-treatment serious AEs; there were 6 deaths, none of which were assessed as related to mepolizumab. For patients with 156 weeks or greater enrollment, the exacerbation rate was 0.74 events/y (weeks 0-156), a 56% reduction from the off-treatment period between DREAM and COLUMBA. For all patients, at the first postbaseline assessment, the mean Asthma Control Questionnaire 5 score was reduced by 0.47 points, and blood eosinophil counts were reduced by 78%, with similar improvements maintained throughout the study. The immunogenicity profile (8% anti-drug antibodies) was consistent with previous studies. CONCLUSION: These data support the long-term safety and efficacy of mepolizumab in patients with SEA.

Effects of systemic corticosteroids on blood eosinophil counts in asthma: real-world data.

Introduction: Systemic corticosteroids (SCS) are effective anti-inflammatory therapies for patients with severe or persistent asthma. Use of SCS reduces blood eosinophil counts; the magnitude and duration of reduction in real-world settings needs further investigation. Objective: To examine the SCS effect on blood eosinophil counts over time among patients with asthma in a real-world setting. Methods: This retrospective study used Reliant Medical Group (Worcester, MA) electronic medical records between January 2011 and December 2015. Patients aged ≥12 years with ≥1 SCS prescription (first: index date), ≥1 asthma diagnosis, and ≥1 eosinophil count in each 12-month pre- and post-index periods were included for the study. Endpoints included SCS treatment patterns, time to SCS discontinuation, and changes in index blood eosinophil counts (≥150, ≥300, and ≥400 cells/µL) with SCS initiation and discontinuation. Results: At index visit, 642 of 1198 included patients had a blood eosinophil count ≥150 cells/µL. After an average initial SCS prescription of 35 mg/day, mean (% change) eosinophil counts at month 1 in the ≥150, ≥300, and≥400 cells/µL subgroups decreased from index by 112 (-30%), 202 (-34%), and 290 (-36%) cells/µL, respectively. Of the patients with an eosinophil count ≥150 cells/µL at index, who discontinued SCS within 7, 14, or 21 days after the index date, 21%, 26%, and 25% had an eosinophil count <150 cells/µL 1-month post-index, respectively. Conclusion: Blood eosinophil counts decreased following initiation of SCS therapy and had not returned to index levels several weeks after SCS discontinuation. The time frame of SCS discontinuation is an important consideration when identifying patients with eosinophilic asthma.

Disease burden in patients with asthma before initiating biologics: A retrospective cohort database study.

Background: Real-world data on the characteristics and burden of disease among patients with asthma before receiving asthma-specific biologics would improve the understanding of the use of these therapies in a clinical setting. Currently, limited data are available on the use of mepolizumab and omalizumab for the treatment of asthma. Objective: To determine the characteristics and disease burden among patients with asthma before initiating treatment with mepolizumab or omalizumab. Methods: This was a retrospective cohort analysis of commercial and Medicare Advantage Plan members from a medical claims database with a new claim for mepolizumab or omalizumab between January 1, 2015, and March 31, 2017 (GSK ID: HO-17-18283). Eligible patients had a diagnosis of asthma and continuous enrollment in the health plan, with clinical and pharmacy benefits for 12 months before initiating asthma-specific biologic treatment (baseline period), and no diagnosis of chronic idiopathic urticaria during the baseline period. Patient characteristics, exacerbations, and asthma-related health care resource utilization and costs were assessed during the baseline period. Results: Overall, 188 and 901 patients prescribed mepolizumab and omalizumab, respectively, were included. In the 12 months before initiating asthma-specific biologic therapy, the patients prescribed mepolizumab were older, had higher blood eosinophil counts, more-frequent exacerbations (2.9 versus 2.0 exacerbations/year; p < 0.001), and more inhaled corticosteroid and systemic corticosteroid use compared with those prescribed omalizumab. Overall, asthma-related health-care resource utilization and costs were similar across both treatment cohorts, although patients prescribed mepolizumab had more pharmacy fills, higher pharmacy costs, and lower clinic costs compared with patients prescribed omalizumab (20.8 versus 16.9 fills, $4504 versus $3102, and $1816 versus $2709, respectively; all p < 0.001). Conclusion: In the 12 months before initiating asthma-specific biologic therapy, the patients prescribed mepolizumab may have a greater disease burden than those prescribed omalizumab. Overall, health-care resource utilization and costs were broadly similar across both treatment cohorts.

Association of depressive symptoms with health status and markers of uncontrolled severe asthma.

Background: There are limited data that describe the association between markers of asthma control and depressive symptoms in severe asthma. Objective: To evaluate the association between depressive symptoms and markers of asthma control in patients with uncontrolled severe eosinophilic asthma. Methods: Baseline data from the MENSA and SIRIUS studies (N = 681) of mepolizumab intervention in severe eosinophilic asthma was used. We analyzed the relationships between depressive symptom severity by using the Beck Depression Inventory (BDI-II) and quality of life by using the St. George's Respiratory Questionnaire (SGRQ), asthma control questionnaire-5 (ACQ-5), polypharmacy, and sleep symptoms. Results: When compared with patients with less severe depressive symptoms, patients with more severe depressive symptoms were predominantly female (81% versus 54%), had a higher mean body mass index (30.56 versus 27.67 kg/m²), were more likely to have a blood eosinophil count of ≥300 cells/uL within the previous 12 months (81% versus 68%), and to have experienced a near-fatal asthma event (16% versus 7%). The mean SGRQ score was higher in the severe BDI-II category compared with the minimal depressive symptoms category, which indicated a worse quality of life (71.6 versus 41.4, p < 0.001). Eighty-nine percent of the patients in the severe BDI-II category had poorly controlled asthma (ACQ-5 score ≥ 1.5) compared with 63% in the minimal category (p < 0.001). Conclusion: Increased severity of depressive symptoms was associated with worse respiratory-related quality of life and asthma control in the patients with severe eosinophilic asthma. These findings highlight the need for a multidimensional approach for the management of uncontrolled asthma, including timely identification of depressive symptoms. Additional research is needed to further explore the interactions between the two common conditions.Clinical trials NCT01691521 and NCT01619508, www.clinicaltrials.gov.

Biomarkers for severe eosinophilic asthma.

The last decade has seen the approval of several new biologics for the treatment of severe asthma-targeting specific endotypes and phenotypes. This review will examine how evidence generated from the mepolizumab clinical development program showed that blood eosinophil counts, rather than sputum or tissue eosinophil counts, evolved as a pharmacodynamic and predictive biomarker for the efficacy of treatment with mepolizumab in patients with severe eosinophilic asthma. Based on the available evidence and combined with clinical judgement, a baseline blood eosinophil threshold of 150 cells/µL or greater or a historical blood eosinophil threshold of 300 cells/µL or greater will allow selection of patients with severe eosinophilic asthma who are most likely to achieve clinically significant reductions in the rate of exacerbations with mepolizumab treatment.

Meta-analysis of asthma-related hospitalization in mepolizumab studies of severe eosinophilic asthma.

BACKGROUND: Studies show that mepolizumab can reduce the frequency of clinically significant exacerbations in patients with severe eosinophilic asthma, compared with placebo. However, important events such as hospitalizations and emergency room visits are rare and difficult to characterize in single studies. OBJECTIVE: We sought to compare hospitalization or hospitalization and/or emergency room visit rates in patients with severe eosinophilic asthma treated with mepolizumab or placebo in addition to standard of care for at least 24 weeks. METHODS: This study was conducted and reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement. PubMed and the GSK Clinical Study Register were searched for suitable studies. The primary end points were the rate of exacerbations requiring hospitalization and the rate of exacerbations requiring hospitalization/emergency room visit. The proportion of patients with 1 or more event was also assessed. All mepolizumab doses were combined and individual patient-level data were analyzed. RESULTS: Four studies (n = 1388) were eligible for inclusion. Mepolizumab significantly reduced the rate of exacerbations requiring hospitalization (relative rate, 0.49; 95% CI, 0.30-0.80; P = .004) and hospitalization/emergency room visit (relative rate, 0.49; 95% CI, 0.33-0.73; P < .001) versus placebo. Significant reductions of 45% and 38% were also observed for the proportion of patients experiencing 1 or more hospitalization and hospitalization and/or emergency room visit, respectively. CONCLUSIONS: Mepolizumab approximately halved exacerbations requiring hospitalization and/or emergency room visits compared with placebo in patients with severe eosinophilic asthma. This treatment addresses a key outcome in a patient population with a high unmet need (GSK Study 204664).

Novel insights of disability assessment in adult myositis.

PURPOSE OF REVIEW: To review the novel development of standardized clinical outcome measures used in adult patients with idiopathic inflammatory myopathies (IIMs). A further aim was to determine what aspects of IIM are covered by these outcome measures according to the International Classification of Functioning, Disability and Health (ICF). RECENT FINDINGS: The sporadic inclusion body myositis functional assessment (sIFA) is the first diagnosis-specific patient-driven patient-reported outcome measure. The adult myositis assessment tool (AMAT) is a new outcome measure assessing physical performance. Also, new criteria to assess response to treatment have been presented for both adults and children with IIM. The ICF provides a standardized frame and structure to report outcome, including functional disability. Using this framework, it is evident that there is a lack of validated patient-reported outcome measures to assess disease aspects important to patient, and that no studies have evaluated life-style factors such as physical activity in these patients. SUMMARY: The sIFA will ensure patient-relevant patient-reported assessment of activity limitations in patients with inclusion body myositis. The AMAT is a partly validated tool that needs to be used in clinical trials for further validation. The response criteria will enhance assessment of individual response to different treatments.

Oral glucocorticoid-sparing effect of mepolizumab in eosinophilic asthma.

BACKGROUND: Many patients with severe asthma require regular treatment with oral glucocorticoids despite the use of high-dose inhaled therapy. However, the regular use of systemic glucocorticoids can result in serious and often irreversible adverse effects. Mepolizumab, a humanized monoclonal antibody that binds to and inactivates interleukin-5, has been shown to reduce asthma exacerbations in patients with severe eosinophilic asthma. METHODS: In a randomized, double-blind trial involving 135 patients with severe eosinophilic asthma, we compared the glucocorticoid-sparing effect of mepolizumab (at a dose of 100 mg) with that of placebo administered subcutaneously every 4 weeks for 20 weeks. The primary outcome was the degree of reduction in the glucocorticoid dose (90 to 100% reduction, 75 to less than 90% reduction, 50 to less than 75% reduction, more than 0 to less than 50% reduction, or no decrease in oral glucocorticoid dose, a lack of asthma control during weeks 20 to 24, or withdrawal from treatment). Other outcomes included the rate of asthma exacerbations, asthma control, and safety. RESULTS: The likelihood of a reduction in the glucocorticoid-dose stratum was 2.39 times greater in the mepolizumab group than in the placebo group (95% confidence interval, 1.25 to 4.56; P=0.008). The median percentage reduction from baseline in the glucocorticoid dose was 50% in the mepolizumab group, as compared with no reduction in the placebo group (P=0.007). Despite receiving a reduced glucocorticoid dose, patients in the mepolizumab group, as compared with those in the placebo group, had a relative reduction of 32% in the annualized rate of exacerbations (1.44 vs. 2.12, P=0.04) and a reduction of 0.52 points with respect to asthma symptoms (P=0.004), as measured on the Asthma Control Questionnaire 5 (in which the minimal clinically important difference is 0.5 points). The safety profile of mepolizumab was similar to that of placebo. CONCLUSIONS: In patients requiring daily oral glucocorticoid therapy to maintain asthma control, mepolizumab had a significant glucocorticoid-sparing effect, reduced exacerbations, and improved control of asthma symptoms.

Mepolizumab treatment in patients with severe eosinophilic asthma.

BACKGROUND: Some patients with severe asthma have frequent exacerbations associated with persistent eosinophilic inflammation despite continuous treatment with high-dose inhaled glucocorticoids with or without oral glucocorticoids. METHODS: In this randomized, double-blind, double-dummy study, we assigned 576 patients with recurrent asthma exacerbations and evidence of eosinophilic inflammation despite high doses of inhaled glucocorticoids to one of three study groups. Patients were assigned to receive mepolizumab, a humanized monoclonal antibody against interleukin-5, which was administered as either a 75-mg intravenous dose or a 100-mg subcutaneous dose, or placebo every 4 weeks for 32 weeks. The primary outcome was the rate of exacerbations. Other outcomes included the forced expiratory volume in 1 second (FEV1) and scores on the St. George's Respiratory Questionnaire (SGRQ) and the 5-item Asthma Control Questionnaire (ACQ-5). Safety was also assessed. RESULTS: The rate of exacerbations was reduced by 47% (95% confidence interval [CI], 29 to 61) among patients receiving intravenous mepolizumab and by 53% (95% CI, 37 to 65) among those receiving subcutaneous mepolizumab, as compared with those receiving placebo (P<0.001 for both comparisons). Exacerbations necessitating an emergency department visit or hospitalization were reduced by 32% in the group receiving intravenous mepolizumab and by 61% in the group receiving subcutaneous mepolizumab. At week 32, the mean increase from baseline in FEV1 was 100 ml greater in patients receiving intravenous mepolizumab than in those receiving placebo (P=0.02) and 98 ml greater in patients receiving subcutaneous mepolizumab than in those receiving placebo (P=0.03). The improvement from baseline in the SGRQ score was 6.4 points and 7.0 points greater in the intravenous and subcutaneous mepolizumab groups, respectively, than in the placebo group (minimal clinically important change, 4 points), and the improvement in the ACQ-5 score was 0.42 points and 0.44 points greater in the two mepolizumab groups, respectively, than in the placebo group (minimal clinically important change, 0.5 points) (P<0.001 for all comparisons). The safety profile of mepolizumab was similar to that of placebo. CONCLUSIONS: Mepolizumab administered either intravenously or subcutaneously significantly reduced asthma exacerbations and was associated with improvements in markers of asthma control.

Error compensation in a pointing system based on Risley prisms.

Risley prisms are widely used for beam pointing in several optical systems. The exact solution for the inverse problem does not exist, except using numerical methods. However, the errors introduced by misalignment are usually greater than the approximation errors. We present a novel method to compensate alignment errors in pointing systems based on Risley prisms. The prism model that we used is based on paraxial approximation with an additional vector to compensate typical alignment errors. Simulation and experimental results show that the improvement in pointing accuracy is achievable even in comparison with exact ray tracing methods.

Efficacy and safety of mepolizumab in Japanese patients with severe eosinophilic asthma.

BACKGROUND: The MENSA trial assessed the efficacy and safety of mepolizumab in patients with severe eosinophilic asthma. This report describes the efficacy and safety of mepolizumab in Japanese patients from MENSA. METHODS: A post hoc analysis of the Japanese subgroup from the randomized, double-blind, placebo-controlled, double-dummy, Phase III MENSA trial (NCT01691521). Patients ≥12 years with severe eosinophilic asthma received mepolizumab 75 mg intravenously (IV), 100 mg subcutaneously (SC), or placebo, every 4 weeks for 32 weeks. The primary endpoint was the annualized rate of exacerbations. Secondary and other endpoints included annualized rate of exacerbations requiring emergency department (ED) visit/hospitalization, morning peak expiratory flow (PEF), St George's Respiratory Questionnaire (SGRQ) score and eosinophil counts. Adverse events (AEs) were monitored. RESULTS: In the Japanese subgroup (N = 50), the rate of clinically significant exacerbations was reduced by 90% (rate ratio [RR]: 0.10; 95% confidence interval [CI]: 0.02-0.57; P = 0.010) with mepolizumab IV and 62% (RR: 0.38; 95% CI: 0.12-1.18; P = 0.094) with mepolizumab SC, versus placebo. No exacerbations requiring ED visit/hospitalization were reported with mepolizumab IV; exacerbations were reduced by 73% (RR: 0.27; 95% CI: 0.06-1.29; P = 0.102) with mepolizumab SC versus placebo. Compared with placebo, mepolizumab IV and SC numerically increased morning PEF from baseline by 40 L/min and 13 L/min, improved quality of life by greater than the minimal clinically important difference (SGRQ: 9.5 [P = 0.083] and 7.9 [P = 0.171] points) and reduced eosinophil counts. AE incidence was similar between treatments. Results were broadly consistent with the overall population. CONCLUSIONS: Mepolizumab was efficacious and well tolerated in Japanese patients with severe eosinophilic asthma, producing similar responses to the overall MENSA population.

Glove port, how do we do it? A low-cost alternative to the single-port approach.

BACKGROUND: The need for cosmetic results in our society and the necessity of an early recovery have promoted the development of minimally invasive techniques, including single-port approach. Some studies have tried to demonstrate the advantages of this access compared with conventional laparoscopic approach. This type of approach requires a high-cost multi-port device, so that some surgeons have tried to create a low-cost homemade device. MATERIALS AND METHODS: With this video we intend to show how to build a glove port, a low-cost alternative for the approach by a single port. CONCLUSIONS: A glove port is a cost effective approach that could be use instead of multi-port device.

Acute and chronic systemic corticosteroid-related complications in patients with severe asthma.

BACKGROUND: Many patients with severe asthma require maintenance treatment with systemic corticosteroids (SCSs) to control daily symptoms and prevent serious acute exacerbations, but chronic SCS use is associated with complications. OBJECTIVE: We sought to evaluate the risk of SCS-related complications by SCS exposure and quantify the associated health care costs and resource use in patients with severe asthma. METHODS: We performed a longitudinal, open-cohort, observational study using health insurance claims data (1997-2013: Medicaid) from Florida, Iowa, Kansas, Missouri, Mississippi, and New Jersey. Eligible patients were 12 years old or older with 2 or more asthma diagnoses and had more than 6 months of continuous SCS use. An open-cohort approach was used to classify patients' follow-up into low, medium, and high SCS exposure (≤ 6, >6-12, and >12 mg/d, respectively). Multivariate generalized estimating equation models were used to estimate the adjusted risk of SCS-related complications for patients with medium and high exposure compared with patients with low exposure and quantify the resulting health care resource use and costs. RESULTS: The study included 3628 patients (mean age, 57.6 years; 68% female). Patients with medium and high SCS exposure had significantly higher risks of SCS-related complications, including infections and cardiovascular, metabolic, psychiatric, ocular, gastrointestinal, and bone-related complications (odds ratio, 1.23-2.12 by complication; P < .05 for all but one) versus those with low (reference group) SCS exposure. Medium and high SCS exposure were also associated with significantly more emergency department visits (incidence rate ratios, 1.31 [P = .0004] and 1.78 [P < .0001]) and inpatient visits (incidence rate ratios, 1.25 [P < .0001] and 1.59 [P < .0001]) versus low SCS exposure. CONCLUSIONS: A significant dose-response relationship was demonstrated between chronic SCS use and risk of SCS-related complications in patients with severe asthma. Effective SCS-sparing strategies might reduce the burden associated with SCS-related complications in patients with severe asthma.
