BACKGROUND Bronchial asthma remains a clinical enigma with poorly controlled symptoms or exacerbations despite regular use of inhaled corticosteroids. Home nebulization offers a simplified solution for the delivery of rescue and maintenance bronchodilators, which is especially true for patients with frequent exacerbations during management of uncontrolled or difficult-to-treat asthma. OBJECTIVE We aimed to assess the clinical impact and outcomes associated with home nebulization—delivered long-acting bronchodilators for uncontrolled or difficult-to-treat asthma. METHODS This observational, concurrent study was conducted with 60 patients at 2 centers during November 2018. Statistical analyses for prebronchodilator forced expiratory volume in one second (FEV1) and Global Initiative for Asthma (GINA) asthma control score in patients on long-acting bronchodilators and corticosteroids were conducted, with two-tailed <i>P</i> values &lt;.05 considered statistically significant. RESULTS Per protocol analyses (53/60) for consecutive cases receiving home nebulization with long-acting bronchodilators and corticosteroids were conducted. The baseline demographics included a male-to-female ratio of 30:23 and mean values of the following: age, 60.3 years (SD 11.8 years); weight, 64 kg (SD 16.8 kg); FEV1, 43% (SD 16%); GINA asthma control score, 3.0 points (SD 0.8 points); serum eosinophil level, 4% (SD 3%); fractional exhaled nitric oxide (FeNO), 12.1 ppb (SD 6 ppb). Of the patients, 100% (53/53) had uncontrolled symptoms, 69.8% (37/53) had prior exacerbations, 100% (53/53) used formoterol/budesonide, and 75.5% (40/53) used glycopyrronium. The per protocol group (n=53) had significantly improved mean prebronchodilator FEV1 (23.7%, SD 29.8%; 0.46 L, SD 0.58 L; <i>P</i>&lt;.001) and GINA asthma control score (2.1 points, SD 0.8 points, <i>P</i>&lt;.001). At baseline, patients (n=40) receiving glycopyrronium/formoterol/budesonide (25/20/500 mcg) nebulization admixture had the following mean values: prebronchodilator FEV1, 38% (SD 15%); GINA asthma control score, 3.0 points (SD 0.8 points); reversibility, 12% (SD 6%); peripheral eosinophil level, 4% (SD 3%); FeNO, 12 ppb (SD 5.7 ppb). In the post hoc analyses, these patients had significantly improved mean prebronchodilator FEV1 of 27.7% (SD 26.2%; 0.54 L, SD 0.51 L; <i>P</i>&lt;.001) at 8 weeks compared with baseline. At baseline, patients (n=13) receiving formoterol/budesonide (20/500 mcg) nebulization had the following mean values: FEV1, 55% (SD 12%); GINA asthma control score, 3.0 points (SD 1.2 points); reversibility, 14% (SD 7%); serum eosinophil level, 4% (SD 3%); FeNO, 13.3 ppb (SD 6.8 ppb). In the post hoc analyses, these patients showed a significant improvement in prebronchodilator FEV1 of 11.2% (SD 13.1%; 0.22 L, SD 0.25 L; <i>P</i>&lt;.001) from baseline. Breathlessness of mild to moderate intensity was reported by 10 cases (10/53, 18.9%), with no other treatment-emergent adverse events or serious adverse events. CONCLUSIONS Home nebulization remains a viable option for symptomatic difficult-to-treat asthma cases with frequent use of rescue medications. Glycopyrronium as add-on therapy offers a synergistic response in patients on corticosteroids with difficult-to-treat asthma.

Introduction: Hyperkalemia (potassium >5.0 mEq/L) affects heart failure patients with renal disease regardless of the use of renin–angiotensin–aldosterone system inhibitors (RAASi). The open-label TOURMALINE study showed that patiromer, a sodium-free, nonabsorbed potassium binder, lowers serum potassium of hyperkalemic patients similarly when given with or without food; unlike prior studies, patients were not required to be taking RAASi. We conducted post hoc analyses to provide the first report of patiromer in patients not taking RAASi. Methods: Hyperkalemic patients received patiromer, 8.4 g/d to start, adjusted to achieve and maintain serum potassium of 3.8 to 5.0 mEq/L. If taking RAASi, stable doses were required. The primary end point was the proportion of patients with serum potassium 3.8 to 5.0 mEq/L at week 3 or 4. This analysis presents data by patients taking or not taking RAASi. Results: Demographics and baseline characteristics were similar in patients taking (n = 67) and not taking RAASi (n = 45). Baseline mean (SD) serum potassium was 5.37 (0.37) mEq/L and 5.42 (0.43) mEq/L in patients taking and not taking RAASi, respectively. Mean (SD) daily patiromer doses were similar (10.7 [3.2] and 11.5 [4.0] g, respectively). The primary end point was achieved in 85% (95% confidence interval [CI]: 74-93) of patients taking RAASi and in 84% (95% CI: 71-94) of patients not taking RAASi. From baseline to week 4, the mean (SE) change in serum potassium was −0.67 (0.08) mEq/L in patients taking RAASi and −0.56 (0.10) mEq/L in patients not taking RAASi (both P < .0001 vs baseline, P = nonsignificant between groups). Adverse events were reported in 26 (39%) patients taking RAASi and 25 (54%) not taking RAASi; the most common adverse event was diarrhea (2% and 11%, respectively; no cases were severe). Five patients (2 taking RAASi) reported 6 serious adverse events; none considered related to patiromer. Conclusions: Patiromer was effective and generally well-tolerated for hyperkalemia treatment, whether or not patients were taking RAAS inhibitors.

Adverse events due to platelet pheresis are not unheard of citrate related reactions being the most common. Most of these events are mild and self limiting. The current study describes adverse events in platelet pheresis using modern apheresis systems. This prospective study included 1455 platelet pheresis procedures done from July 2016 to December 2017. Procedures were performed on Hemonetics MCS+, Trima Accel and Cobe spectra cell separators. The endpoint of each procedure was a yield of 3 × 1011 platelets (PLTs) per unit. Donor adverse reaction if any was managed, reported, and documented. The median age of donors was 31 years with male to female ratio of 13:1. The median body surface area and body mass index were 1.64 m2 and 22.4 kg/m2, respectively. The mean PLT count of donors was 199.8 × 103/uL with a mean hemoglobin value of 13.6 g/dl. ACD infusion was significantly more in the Hemonetics MCS+, (P< 0.01). Donation time was least with the Trima compared to Hemonetics MCS+ (P< 0.01) and Cobe (P< 0.001). Total whole blood volume processed was higher in Hemonetics MCS+, (P< 0.01). Paresthesia due to citrate toxicity was the most common adverse reaction (65.3%), and vascular injury was observed in only five donors. The overall incidence of adverse reaction was 3.4%. Serious adverse events were not observed. The modern generation apheresis machines are more donors friendly and cause less adverse reactions compared to the older versions. Good donor screening, optimized donor physiognomic and hematological values and skilled operators are the key factors in reaction reduction by apheresis. Faridpur Med. Coll. J.

Background: Chronic obstructive pulmonary disease (COPD) guidelines recommend both long-acting and dual bronchodilator therapy. It is unclear if there are differences in efficacy and safety. Objective: This meta-analysis evaluates the efficacy of dual therapy with long-acting β-agonist (LABA) + long acting muscarinic antagonist (LAMA) compared with monotherapy with LAMA for COPD. Methods: We searched PubMed, CINAHL, and Web of Science databases from inception through March 2020 to identify English-language, prospective randomized controlled trials (RCTs) that compared dual therapy with monotherapy in adult patients with COPD. Risk of bias was assessed using the Jadad score. Overall analysis was performed using Review Manager 5.3. Treatment effect was determined with the random-effects model using the Mantel-Haenszel method and was reported as mean difference (MD) with 95% CI. Results: A total of 18 RCTs were included (n = 6086; median Jadad score 5/5) that compared LAMA + LABA with LAMA. There was a greater improvement in forced expiratory volume at 1 s (FEV1) with dual therapy compared with LAMA: MD = 0.08; 95% CI = [0.05, 0.11]. There was no difference in St George Respiratory Questionnaire (SGRQ) scores between groups: OR = −0.85; 95% CI = [−1.83, 0.13]. There were no differences in overall adverse events (OR = 1.00; 95% CI = 0.92, 1.09), serious adverse events (OR = 1.01; 95% CI = 0.86, 1.18), or cardiovascular events (OR = 0.88; 95% CI = 0.58, 1.34). Conclusion and Relevance: Dual therapy improves FEV1 and is as safe as LAMA. Dual therapy does not improve SGRQ scores more than LAMA.

788 Background: The phase 3 RECOURSE showed that treatment with trifluridine/tipiracil in patients (pts) with refractory metastatic colorectal cancer was associated with significantly improved survival versus placebo (7.1 versus 5.3 months, respectively; HR for death 0.68, 95% CI 0.58–0.81, p < 0.001), with few serious adverse events. Trifluridine/tipiracil is administered in 4-week cycles comprising 2 weeks with 5 days at 35 mg/m2 bid followed by 2 rest days, and then a 2-week rest period. Exploration of timing for AEs, particularly within the first cycle of treatment, is important for pt monitoring in the outpatient setting. Methods: We performed a post hoc analysis of the RECOURSE safety population (533 trifluridine/tipiracil; 265 placebo) to explore timing of hematological and nonhematological AEs. Results: Grade ≥ 3 adverse events (AEs) were more frequent with trifluridine/tipiracil than placebo for both hematological AEs (38% vs 0% neutropenia; 4% vs 0% febrile neutropenia; 18% vs 3% anemia; and 5% vs < 1% thrombocytopenia) and nonhematological AEs (2% vs 1% nausea; 2% vs < 1% vomiting; and 3% vs < 1% diarrhea). The median time to nadir in cycle 1 for hematological events was 28 days (17–31) for grade ≥ 3 neutropenia, 22 days (9–39) for grade ≥ 3 anemia, and 18 days (9–33) for grade ≥ 3 thrombocytopenia; similar values were obtained in subsequent cycles. The median times to nadir and values at nadir over the whole treatment duration (all cycles) are presented in the table for hematological and nonhematological AEs. Conclusions: Hematological and nonhematological AEs with trifluridine/tipiracil appear to be most intense towards the end of treatment cycles, which is reassuring for its use in the outpatient setting. Clinical trial information: NCT01607957. [Table: see text]

ABSTRACT Objective: To determine whether long-acting muscarinic antagonists (LAMAs) provide superior therapeutic effects over long-acting β2 agonists (LABAs) for preventing COPD exacerbations. Methods: This was a systematic review and meta-analysis of randomized clinical trials involving patients with stable, moderate to severe COPD according to the Global Initiative for Chronic Obstructive Lung Disease criteria, treated with a LAMA (i.e., tiotropium bromide, aclidinium, or glycopyrronium), followed for at least 12 weeks and compared with controls using a LABA in isolation or in combination with a corticosteroid. Results: A total of 2,622 studies were analyzed for possible inclusion on the basis of their title and abstract; 9 studies (17,120 participants) were included in the analysis. In comparison with LABAs, LAMAs led to a greater decrease in the exacerbation rate ratio (relative risk [RR] = 0.88; 95% CI: 0.84-0.93]; a lower proportion of patients who experienced at least one exacerbation (RR = 0.90; 95% CI: 0.87-0.94; p < 0.00001); a lower risk of exacerbation-related hospitalizations (RR = 0.78; 95% CI: 0.69-0.87; p < 0.0001); and a lower number of serious adverse events (RR = 0.81; 95% CI: 0.67-0.96; p = 0.0002). The overall quality of evidence was moderate for all outcomes. Conclusions: The major findings of this systematic review and meta-analysis were that LAMAs significantly reduced the exacerbation rate (exacerbation episodes/year), as well as the number of exacerbation episodes, of hospitalizations, and of serious adverse events.
