RESUMO
Background: A woman in her seventies presented to the accident and emergency department (A&E) with shortness of breath that had increased over a period of three weeks. She had a history of COPD, hypertension and polymyalgia rheumatica. A medication error involving methotrexate, used for autoimmune diseases, was discovered during her medical history review. Case presentation: The patient arrived with stable vital signs, including 94 % oxygen saturation and a respiratory rate of 20 breaths/min. She had been taking 2.5 mg of methotrexate daily for the past three weeks instead of the prescribed weekly dose of 15 mg. Other examinations revealed no alarming findings, except for a slightly elevated D-dimer level. Interpretation: Considering her medical history and exclusion of other differential diagnoses, methotrexate toxicity was suspected. The patient was admitted to the hospital and intravenous folinic acid was initiated as an antidote treatment. Five days later, the patient was discharged with an improvement in the shortness of breath. This case underscores the importance of effective communication in health care, particularly in complex cases like this, where understanding dosages and administration is crucial. Medical history, clinical examinations and medication reviews, often involving clinical pharmacists, are vital in the A&E to reveal medication errors.

Purpose: The aim of this study was to determine the effect of ABCB1 genetic polymorphism and renal function on the occurrence of ticagrelor-related dyspnea. Patients and Methods: A total of 299 patients with acute with type 1, 2, or 3 myocardial infarction (with and without ST-segment elevation), who underwent coronary angiography and PTCA with stent implantation and were treated with antiplatelet drugs (ticagrelor and aspirin), were enrolled in this prospective study. For all enrolled patient's platelet aggregation (induction with high-sensitivity adenosine diphosphate, ADP HS) testing was performed using a MULTIPLATE® analyzer. Venous blood was also collected for genotyping. Results: Patients experiencing ticagrelor-related dyspnea had lower ADP HS value (ADP HS ≤ 19.5 U; OR = 2.254; P = 0.009), higher creatinine concentration (>90 µmol/l; OR = 3.414; P = 0.019), and lower GFR value (<60 mL/min/1.73 m2; OR = 2.211; P = 0.035). ABCB1 T allele was associated with ticagrelor-related dyspnea (OR = 2.550; P = 0.04). Conclusion: Ticagrelor-related dyspnea was found to be related to low platelet aggregation, increased plasma creatinine concentration, decreased GFR, and ABCB1 T allele. Carriers of the ABCB1 T allele had a higher plasma creatinine concentration that could be associated with an inhibitory effect of ticagrelor on P-glycoprotein function.

ETHNOPHARMACOLOGICAL RELEVANCE: Zedoary turmeric oil injection (ZTOI) extracted from the rhizome extract of Curcuma phaeocaulis Valeton, Curcuma wenyujin Y. H. Chen et C. Ling or Curcuma kwangsiensis S. G. Lee et C. F. Liang, is widely used for the treatment of virus-induced upper respiratory tract infections, peptic ulcers, viral pneumonia, etc. However, it has attracted widespread attention because it often causes adverse drug reactions (ADRs), including dyspnea. However, little is known about the mechanism underlying dyspnea caused by ZTOI, which limits its clinical application. AIM OF THE STUDY: To investigate the major pathophysiologic signatures and underlying mechanism of ZTOI-related dyspnea. METHODS: Respiratory function detection was used to explore the pathophysiologic signature of dyspnea induced by ZTOI. UV-vis absorption spectroscopy and isothermal titration calorimetry were applied to test the interaction between ZTOI and hemoglobin (Hb). GCâMS was used to identify the main components in ZTOI. Molecular docking, surface plasmon resonance, and circular dichroism spectroscopy were employed to test the reaction between ß-elemene and Hb. Western blot was performed to investigate the effect of ß-elemene on the hypoxia signaling pathway. RESULTS: The results showed that ZTOI-induced dyspnea was related to a decreased oxygen carrying capacity of Hb. The molecular interaction between ZTOI and Hb was proven. Notably, ß-elemene in ZTOI exhibited high binding affinity to Hb and altered its secondary structure. Furthermore, it was found that ß-elemene downregulated the expression of prolyl hydroxylase-domain protein 2 and upregulated the expression of hypoxia-inducible factor-1α. CONCLUSIONS: Our study is valuable for better understanding the pathophysiological characteristics and underlying mechanism of ZTOI to ensure its safe clinical application. We also provided a strategy to elucidate the underlying mechanism based on inspiration from clinical ADR phenotypes for investigating other medical products with ADRs in the clinic.

OBJECTIVES: Morphine is effective in alleviating dyspnoea in patients with cancer. We aimed to investigate the effectiveness and safety of morphine administration for refractory dyspnoea in patients with advanced heart failure (HF). METHODS: We conducted a multicentre, prospective, observational study of hospitalised patients with advanced HF in whom morphine was administered for refractory dyspnoea. Morphine effectiveness was evaluated by dyspnoea intensity changes, assessed regularly by both a quantitative subjective scale (Visual Analogue Scale (VAS; graded from 0 to 100 mm)) and an objective scale (Support Team Assessment Schedule-Japanese (STAS-J; graded from 0 to 4 points)). Safety was assessed by vital sign changes and new-onset severe adverse events, including nausea, vomiting, constipation and delirium based on the Common Terminology Criteria for Adverse Events. RESULTS: From 15 Japanese institutions between September 2020 and August 2022, we included 28 hospitalised patients with advanced HF in whom morphine was administered (mean age: 83.8±8.7 years, male: 15 (54%), New York Heart Association class IV: 26 (93%) and mean left ventricular ejection fraction: 38%±19%). Both VAS and STAS-J significantly improved from baseline to day 1 (VAS: 67±26 to 50±31 mm; p=0.02 and STAS-J: 3.3±0.8 to 2.6±1.1 points; p=0.006, respectively), and thereafter the improvements sustained through to day 7. After morphine administration, vital signs including blood pressure, pulse rate and oxygen saturation did not change, and no new-onset severe adverse events occurred through to day 7. CONCLUSIONS: This study suggested acceptable effectiveness and safety for morphine administration in treating refractory dyspnoea in hospitalised patients with advanced HF.

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality globally. In the major revision of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 report, the scientific committee concluded that the use of long-acting ß2-agonist/inhaled corticosteroids (LABA/ICS) is not encouraged in patients with COPD. However, current prescribing patterns reveal significant use of LABA/ICS. In this paper, the evidence behind the current practice and the latest treatment recommendations is reviewed. We compare the efficacy and safety of combination therapy with long-acting muscarinic antagonist (LAMA) and LABA vs LABA/ICS and note that LAMA/LABA combinations have reduced the annual rate of moderate/severe exacerbations, delayed the time to first exacerbation, and increased post-dose FEV1 vs ICS-based regimens. The GOLD 2023 report recommends treatment with LABA and LAMA combination (preferably as a single inhaler) in patients with persistent dyspnea, with initiation of ICS in patients based on the symptoms (dyspnea and exercise intolerance as indicated by modified Medical Research Council [mMRC] score ≥ 2 and COPD Assessment Test [CAT™] > 20), blood eosinophil count (≥ 300 cells/µL), and exacerbation history (history of hospitalizations for exacerbations of COPD and ≥ 2 moderate exacerbations per year despite appropriate long-acting bronchodilator maintenance therapy). We describe practical recommendations for primary care physicians to optimize therapy for their patients and prevent overuse of ICS-based regimens. We advocate adherence to current recommendations and a greater focus on effective treatments to successfully control symptoms, minimize exacerbation risk, preserve lung function, maximize patient outcomes, and reduce the burden of drug-related adverse events.
Chronic obstructive pulmonary disease (COPD) is a common disease of the lungs associated with continued respiratory symptoms and airflow limitation. COPD causes symptoms such as breathlessness, cough, and production of phlegm, and, if not properly managed, these symptoms may get worse and result in flare-ups, also termed exacerbations. COPD management includes controlling symptoms while reducing the risk of exacerbations. COPD treatments include bronchodilators and inhaled corticosteroids (ICS). Bronchodilators help by widening the airways, making it easier to breathe. The two types of bronchodilators are long-acting muscarinic antagonists (LAMAs; these drugs prevent closing of the airways) and long-acting ß2-agonists (LABAs; these drugs relax the muscles around the airways to help keep the airways open for a longer time). ICS may reduce swelling in the airways in some patients with COPD. However, the use of ICS-based regimens as the first treatment choice has been linked to health risks and is not in keeping with the recent national and international recommendations. In this narrative review, we examine why the use of ICS-based regimens is still growing and explore, based on available evidence, and why this treatment course may not be optimal for most patients with COPD. We discuss how the treatment for COPD has changed over time, and our findings support the use of LAMA and LABA as the first course of therapy in many patients with COPD. We conclude that greater adherence to the treatment guidelines can help to improve treatment outcomes for many patients with COPD.

BACKGROUND: Nearly 20% of patients on ticagrelor experience dyspnea, which may lead to treatment discontinuation in up to one-third of cases. OBJECTIVES: The authors sought to evaluate the incidence, predictors, and outcomes of dyspnea-related ticagrelor discontinuation after percutaneous coronary intervention (PCI). METHODS: In the TWILIGHT (Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention) trial, after 3 months of ticagrelor plus aspirin, patients were maintained on ticagrelor and randomized to aspirin or placebo for 1 year. The occurrence of dyspnea associated with ticagrelor discontinuation was evaluated among all patients enrolled in the trial. A landmark analysis was performed at 3 months after PCI, that is, the time of randomization. Predictors of dyspnea-related ticagrelor discontinuation were obtained from multivariable Cox regression with stepwise selection of candidate variables. RESULTS: The incidence of dyspnea-related ticagrelor discontinuation was 6.4% and 9.1% at 3 and 15 months after PCI, respectively. Independent predictors included Asian race (lower risk), smoking, prior PCI, hypercholesterolemia, prior coronary artery bypass, peripheral artery disease, obesity, and older age. Among 179 patients who discontinued ticagrelor because of dyspnea after randomization, ticagrelor monotherapy was not associated with a higher risk of subsequent ischemic events (composite of all-cause death, myocardial infarction, or stroke) compared with ticagrelor plus aspirin (5.0% vs 7.1%; P = 0.566). CONCLUSIONS: In the TWILIGHT trial, dyspnea-related ticagrelor discontinuation occurred in almost 1 in 10 patients and tended to occur earlier rather than late after PCI. Several demographic and clinical conditions predicted its occurrence, and their assessment may help identify subjects at risk for therapy nonadherence.

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction to Aspergillus fumigatus that occurs in patients with asthma or cystic fibrosis. Here, we report a case of a young female with bronchial asthma who presented to our hospital with worsening breathlessness on exertion. She was diagnosed to have ABPA and was initiated on oral itraconazole while continuing inhaled long acting beta-2 adrenergic agonist and medium dose inhaled corticosteroid (ICS) for her asthma. Three months after initiation of therapy, the patient had significant improvement in breathlessness. However, she had weight gain, facial puffiness, increased facial hair and development of striae on her inner thighs, calf and lower abdomen. Her serum cortisol levels were found to be suppressed and hence a diagnosis of iatrogenic Cushing's syndrome was made. Our case describes the potentially serious interaction between ICS and oral itraconazole, a treatment very commonly prescribed in patients with ABPA.

Dyspnea is a prevalent symptom that significantly reduces quality of life of cancer patients. Palliative treatment is necessary when the symptoms do not respond to treatment for their cause. Opioids are widely used as pharmacological therapy, but evidence for individual agents is inconsistent. The purpose of this study was to evaluate the efficacy and safety of opioids for dyspnea in cancer patients. We searched the CENTRAL, MEDLINE, EMBASE, and ICHUSHI for studies using opioids for dyspnea in adult cancer patients reported by September 2019. Screening of the retrieved literature and assessment of risk of bias and outcomes were performed by two independent authors. A meta-analysis was performed on the primary endpoint, relief of dyspnea, and secondary endpoints including quality of life, somnolence as a side effect, and serious adverse events. Twelve randomized controlled trials were evaluated regarding relief of dyspnea. Somnolence and serious adverse events were evaluated in seven and four randomized controlled trials, respectively, but no randomized controlled trials were evaluable for quality of life. Overall, opioids were more effective than placebo for dyspnea (standardized mean difference - 0.43, 95% confidence interval [CI] - 0.75 to - 0.12). Although significant difference was found between systemic morphine and placebo in the drug-specific analysis, no significant difference could be detected in the other analyses. Systemic administration of opioids is more effective than placebo in relieving dyspnea in cancer patients. Robust evidence on the efficacy and safety of opioids on dyspnea in cancer patients is lacking, and further studies are needed.

BACKGROUND: Occupational exposure to various types of cleaning agents may increase the risk of adverse respiratory health among cleaners. This study investigated the relationship between exposure to cleaning and disinfecting agents, using a job-task and exposure intensity metric, and respiratory outcomes among cleaners. METHODS: A sample of 174 cleaners was selected from three public hospitals in Durban. A questionnaire was used to collect demographic and occupational information, and spirometry, including post-bronchodilator measures, was conducted according to the American Thoracic Society guidelines and skin prick testing were performed. Exposure metrics for job tasks and chemical exposures were created using frequency and employment-lifetime duration of exposure. Multivariate analysis regression models used job task and exposure intensity metrics. RESULTS: Doctor-diagnosed asthma prevalence was 9.8%. Breathlessness with wheeze (22.4%) was the prevalent respiratory symptom. Positive responses to skin prick testing were seen in 74 (43.2%). There was a statistically significant increased risk for shortness of breath with exposure to quaternary ammonium compounds (odds ratio [OR]: 3.44; 95% confidence interval [CI]: 1.13-10.5) and breathlessness with exposure to multipurpose cleaner (OR: 0.34; CI: 0.12-0.92). The losses in percent-predicted forced expiratory volume in 1 s (FEV1) ranged from 0.3%-6.7%. Results among the bronchodilator-positive (8.6%) showed lung function losses twofold greater when compared to the total study population with percentage predicted FEV1 (-22.6 %; p < 0.000). CONCLUSION: Exposure to certain cleaning and disinfectant agents adversely affects respiratory health, particularly lung function. This effect, while seen generally among cleaning workers, is more pronounced among those with pre-existing reversible obstructive lung disease.

Objective: The objective of this systematic review is to consolidate the existing evidence on opioid use, including administration, dosing, and efficacy, for the relief of dyspnea at end of life. The overarching goal is to optimize clinical management of dyspnea by identifying patterns in opioid use, improving opioid management of dyspnea, and to prioritize future research. Background: Opioids are commonly used in the management of dyspnea at end of life, yet specific administration guidelines are limited. A greater understanding of the effectiveness of opioids in relieving end-of-life dyspnea with consideration of study design, patients, and opioids, including dyspnea evaluation tools and outcomes, will leverage development of standardized administration and dosing. Methods: A PRISMA-guided systematic review using six databases identified quality studies of opioid management for patients with dyspnea at end of life. Results: Twenty-three references met review inclusion criteria, which included terminally ill cancer and noncancer patients with various diagnoses. Studies included two randomized controlled trials, and three nonrandomized experimental, three prospective observational, one cross-sectional, and one case series. Thirteen retrospective chart reviews were also included due to the limited rigorous studies rendered by the search. Thirteen studies evaluated morphine, followed by fentanyl (6), oxycodone (5), general opioid use (4), and hydromorphone (2). Routes of administration were parenteral, oral, combination, and nebulization. Dyspnea was evaluated using self-reporting and non-self-reporting evaluation tools. Sedation was the most reported opioid-related adverse effect. Discussion: Challenges persist in conducting end-of-life research, preventing consensus on standardization of opioid treatment for dyspnea within this specific palliative time frame. Future robust prospective trials using specific, accurate assessment with reassessment of dyspnea/respiratory distress, and consideration of opioid tolerance, polypharmacy, and comorbidities are required.

BACKGROUND: Systemic corticosteroids are commonly prescribed for palliation of dyspnoea in patients with cancer, despite scarce evidence to support their use. We aimed to assess the effect of high-dose dexamethasone versus placebo on cancer-related dyspnoea. METHODS: The parallel-group, double-blind, randomised, controlled ABCD (Alleviating Breathlessness in Cancer Patients with Dexamethasone) trial was done at the at the University of Texas MD Anderson Cancer Center and the general oncology clinic at Lyndon B Johnson General Hospital (both in Houston, TX, USA). Ambulatory patients with cancer, aged 18 years or older, and with an average dyspnoea intensity score on an 11-point numerical rating scale (NRS; 0=none, 10=worst) over the past week of 4 or higher were randomly assigned (2:1) to receive dexamethasone 8 mg orally every 12 h for 7 days followed by 4 mg orally every 12 h for 7 days, or matching placebo capsules for 14 days. Pharmacists did permuted block randomisation with a block size of six, and patients were stratified by baseline dyspnoea score (4-6 vs 7-10) and study site. Patients, research staff, and clinicians were masked to group assignment. The primary outcome was change in dyspnoea NRS intensity over the past 24 h from baseline to day 7 (±2 days). Analyses were done by modified intention-to-treat (ie, including all patients who were randomly assigned and started the study treatment, regardless of whether they completed the study). Enrolment was stopped after the second preplanned interim analysis, when the futility criterion was met. This study is registered with ClinicalTrials.gov (NCT03367156) and is now completed. FINDINGS: Between Jan 11, 2018, and April 23, 2021, we screened 2867 patients, enrolled 149 patients, and randomly assigned 128 to dexamethasone (n=85) or placebo (n=43). The mean change in dyspnoea NRS intensity from baseline to day 7 (±2 days) was -1·6 (95% CI -2·0 to -1·2) in the dexamethasone group and -1·6 (-2·3 to -0·9) in the placebo group, with no significant between-group difference (mean 0 [95% CI -0·8 to 0·7]; p=0·48). The most common all-cause grade 3-4 adverse events were infections (nine [11%] of 85 patients in the dexamethasone group vs three [7%] of 43 in the placebo group), insomnia (seven [8%] vs one [2%]), and neuropsychiatric symptoms (three [4%] vs none [0%]). Serious adverse events, all resulting in hospital admissions, were reported in 24 (28%) of 85 patients in the dexamethasone group and in three (7%) of 43 patients in the placebo group. No treatment-related deaths occurred in either group. INTERPRETATION: High-dose dexamethasone did not improve dyspnoea in patients with cancer more effectively than placebo and was associated with a higher frequency of adverse events. These data suggest that dexamethasone should not be routinely given to unselected patients with cancer for palliation of dyspnoea. FUNDING: US National Cancer Institute.

Genital aesthetic procedures have increased in popularity among women and men. Many clinicians tried to expand the application of fill injection by using it for genital aesthetic injection. However, this procedure is not so safe as imagined and may lead to a fatal complication of pulmonary embolism. This article summarizes the clinical manifestations and proposed mechanism of the filler-induced non-thrombotic pulmonary embolism (FINTPE) cases. A literature review was performed with the search keywords including "genital aesthetic injection, vaginal injection, vaginoplasty, vaginal tightening, penile augmentation, penis injection, hyaluronic acid, fat grafting, pulmonary embolism, alveolar hemorrhage, hypoxemia, and dyspnea." Among the 14 cases from 11 articles enrolled, 12 patients were female, and two were male. Eight patients received silicone injection, followed by two received fat grafting and hyaluronic acid injection, respectively. All the female patients had one single injection site, including 11 cases for the vaginal wall and one for G-spot, while all the male patients received injections into the penis and scrotum. The main symptoms were dyspnea and chest pain. Almost 60% of FINTPE patients presented respiratory disorders within 12 hours post-operation. Treatment includes oxygen therapy, corticosteroids, and anticoagulation. Five patients improved with an average of 14.6-day treatment, and seven died due to organ failures. Genital aesthetic filler injections are experimental procedures without being strictly reviewed or approved. As a severe complication following these procedures, FINTPE requires cautious performance, careful prevention, timely identification, and treatment to decrease its incidence and mortality.

Purpose: Dyspnea is a leading symptom of COPD that causes presentations in emergency departments or negatively impacts on them. Guideline-based inhalation therapies are intended to reduce dyspnea in COPD patients. This study analyzed how common guideline recommended inhalation therapy regimens are occurring in clinical practice among COPD patients presenting to emergency departments due to adverse drug reactions in polytherapy using data of the German ADRED database. Patients and Methods: In total, 269 COPD cases were identified. In a further analysis, all cases were analyzed for documented GOLD stage and guideline-recommended inhalation therapy for COPD. Dyspnea and other symptoms identified during ED presentation were analyzed and compared between patients who did and did not receive the guideline's recommended inhalation therapy. Results: In this observation, 41% (n = 46) of all 112 cases with a documented COPD and GOLD stage received an underdosed therapy according to current guidelines. Dyspnea was the most common identified symptom (32%, n = 36) in this cohort and occurred more often in patients who received an underdosage of inhalation therapy (p < 0.01). Conclusion: Patients with COPD presenting to ED with ADRs show a high rate of non-guideline-recommended inhalation therapy and present more often with dyspnea compared to those COPD patients who received an adequate dosing of inhalation therapy.

BACKGROUND Khat (Catha edulis) is a plant cultivated in Ethiopia, East African, and the Arabian Peninsula. Long-term khat consumption has been associated with increased rates of periodontal diseases, esophagitis, psychosis, and cardiovascular issues such as cerebrovascular accidents, myocardial ischemia, and ischemic cardiomyopathy (CM). We report a case of khat-induced non-ischemic CM in a patient with no other known cardiovascular risk factors and highlight a cardiovascular effect of chronic khat consumption. CASE REPORT A 54-year-old Yemeni man with no known medical history but a chronic khat chewer presented with worsening exertional dyspnea for 6 months and associated pedal edema. Laboratory studies were remarkable for elevated B-type natriuretic peptide (BNP). Electrocardiogram (EKG) revealed normal sinus rhythm with non-specific T wave inversions (TWI) in V5-V6. A computed tomography (CT) scan of the chest showed bilateral pleural effusions with interlobular septal thickening. Transthoracic echocardiogram (TTE) showed a left ventricular ejection fraction (LVEF) of 16-20% and global CM. Coronary angiography revealed normal coronaries. CONCLUSIONS Chronic khat consumption is being recognized as a dangerous habit with serious health consequences and its association with ischemic CM is well documented. The findings of ischemic cardiac changes of acute coronary syndrome in a patient with normal coronary arteries raises the possibility that khat toxicity was associated with coronary artery spasm due to its amphetamine-like stimulatory effects. Although further research is required to substantiate this relationship, it is imperative that khat consumption be considered a risk factor when assessing for CM.

BACKGROUND: Corona virus disease 2019 (COVID-19) has spread around the world since its outbreak, and there is no ascertained effective drug up to now. Lianhua Qingwen (LHQW) has been widely used in China and overseas Chinese, which had some advantages in the treatment of COVID-19. OBJECTIVE: To evaluate the efficacy and safety of LHQW for COVID-19 by conducting a systematic review with meta-analysis. METHODS: A comprehensive literature search was conducted in 12 electronic databases from their establishment to October 30, 2021. Note Express 3.2.0 was used for screening of trials, and the data was independently extracted in duplicate by 2 researchers. The risk of bias of randomized controlled trials (RCTs) and retrospective studies were assessed by using the Cochrane collaboration tool and Newcastle Ottawa Scale, respectively, followed by data analysis using RevMan 5.3. The RCTs or retrospective studies to treat COVID-19 using LHQW were included. The intervention measures in the experimental group were LHQW alone or combined with chemical drugs (LCWC), and that in the control group were chemical drugs (CDs). Outcome measures included computed tomography (CT) recovery rate, disappearance rates of primary (fever, cough, fatigue), respiratory, gastrointestinal and other symptoms, exacerbation rate and adverse reaction. Subgroup analysis was conducted according to whether LHQW was combined with CDs and the different treatment methods in the control group. RESULTS: Nine trials with 1,152 participants with COVID-19 were included. The CT recovery rates of LHQW and LCWC were 1.36 and 1.32 times of CDs, respectively (P<0.05). Compared with CDs, LCWC remarkably increased the disappearance rates of fever, cough, fatigue, expectoration, shortness of breath, and muscle soreness (P<0.05). LHQW also obviously decreased the exacerbation rate, which was 0.45 times of CDs alone (P<0.05). There was no obvious difference between LCWC and CDs in adverse reaction (P>0.05). CONCLUSIONS: LHQW was more suitable for treating COVID-19 patients with obvious expectoration, shortness of breath and muscle soreness. LHQW had advantages in treating COVID-19 with no obvious exacerbation. (PROSPERO No. CRD42021235937).

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neuromuscular disease with no curative therapies. Edaravone (Radicava®) (Mitsubishi Tanabe Pharma Corporation, Tokyo, Japan), approved in the United States (US) for ALS in adults in 2017, was shown in a clinical trial to slow the rate of physical functional decline in ALS and is administered intravenously. The aim of this paper is to summarize the observed safety profile from real-world patient use during the first 3 years of edaravone availability in the US. METHODS: Edaravone usage data were collected, and adverse events (AEs) were identified from a postmarketing safety database from August 8, 2017 through August 7, 2020 (cutoff date). RESULTS: As of October 3, 2020, 5207 ALS patients had been treated with edaravone. As of August 7, 2020, the most commonly reported AEs included death (not specified), drug ineffective, disease progression, therapeutic response unexpected, fall, asthenia, fatigue, muscular weakness, gait disturbance, and dyspnea. The most commonly reported serious AEs (SAEs) included death (not specified), pneumonia, disease progression, ALS, fall, dyspnea, respiratory failure, device-related infection, hospitalization, and injection-site infection. There were 687 deaths, with 494 reported as death without specifying the cause. Deaths were most commonly attributed to ALS, disease progression, respiratory failure, or pneumonia. Review for administration-site reactions revealed 95 AEs, including 34 site infections, with 22 SAEs (all non-fatal). Five non-fatal SAEs of anaphylaxis were reported. CONCLUSION: In the postmarketing reporting to date, no new safety signals were identified beyond those already known from the edaravone clinical trial program.

Because there is a solid pharmacological rationale based on positive interactions between long-acting muscarinic receptor antagonists (LAMAs) and long-acting ß-agonists (LABAs) for their ability to relax human airway smooth muscle in vitro alongside several randomised controlled trials (RCTs) and real-world observational studies that support the use of LAMA/LABA fixed-dose combinations (FDCs) for the treatment of patients with chronic obstructive pulmonary disease (COPD), in this narrative review we discuss the preclinical and clinical proofs supporting the use of LAMA + LABA therapy in COPD and why this therapeutic approach optimises bronchodilation. Robust evidence indicates that all LAMA/LABA FDCs are consistently more effective than LAMA or LABA administered alone in improving lung function, dyspnoea, quality of life and exercise capacity in patients with COPD. However, the ability of dual bronchodilation with FDCs of LAMA/LABA to prevent or reduce the risk of COPD exacerbations remains unclear due to conflicting data from large RCTs, despite several mechanisms explaining why such combinations should be of value in decreasing the frequency of COPD exacerbations. Both LABAs and LAMAs mechanistically can affect the cardiovascular system, but from clinical studies to date, LAMA/LABA FDCs have an acceptable cardiovascular safety profile, at least in the COPD population enrolled in RCTs. Indirect evidence suggests that some FDCs may even exert a protective role against serious cardiovascular adverse events compared to monotherapies. Consequently, several LAMA/LABA FDCs have been developed and approved for clinical use as treatments for patients with COPD. However, to date, there are unfortunately very few head-to-head studies comparing the safety and efficacy of different LAMA/LABA FDCs, making it difficult to choose the most appropriate combination, although the use of meta-analyses has provided some information in this regard. Endurance time Exercise time until exhaustion measured by a standard endurance test. Inspiratory capacity The maximum volume of air that can be inspired after reaching the end of a normal, quiet expiration. It is the sum of the tidal volume and the inspiratory reserve volume. St George's Respiratory Questionnaire (SGRQ) A tool to measure health status in patients with respiratory disease. It has three domains: symptoms, activity and impacts. A total score is also calculated. A minimal important difference (range) of â¼4 (2.4-5.6) units in the SGRQ total score is supported by published studies. Surface under the cumulative ranking curve analysis (SUCRA) A numerical representation of the overall rating that displays a single value for each treatment. SUCRA levels vary from 0% to 100%. The higher the SUCRA value and the closer it is to 100%, the more likely therapy is in the top rank or one of the top rankings; the lower the SUCRA value and the closer it is to 0%, the more likely therapy is in the bottom rank or one of the bottom ranks. Transition dyspnoea index (TDI) Widely used in clinical studies of COPD to measure shortness of breath, indicating change in response to an intervention. The total score ranges from -9 to 9; the negative value indicates deterioration, whereas a positive value indicates improvement. There is sufficient evidence to suggest that the minimal important difference for the TDI score is 1 unit. Trough FEV1 The mean volume of air that can be forced out in 1 second approximately 12 (with a twice-daily agent) or 24 (with a once-daily agent) hours after the last administration of bronchodilator.

BACKGROUND: Immune checkpoint inhibitors (ICI), combined with hypomethylating agents, can be used to treat acute myeloid leukemia (AML), but this strategy results in a high rate of pneumonitis. The authors sought to determine risk factors for pneumonitis development and whether pneumonitis increased mortality. METHODS: The authors conducted a retrospective review of 258 AML patients who received ICI-containing regimens from 2016 to 2018. A multidisciplinary adjudication committee diagnosed pneumonia and pneumonitis by reviewing symptoms, imaging, microbiology, and response to therapies. To measure risk factors for pneumonitis and mortality, multivariate Cox proportional hazards models were constructed. Pneumonia, pneumonitis, and disease progression were modeled as a time-dependent variable and incorporated a standard risk set modifying variables into the models. RESULTS: Thirty patients developed pneumonitis (12%). Of these, 17 had partial or complete resolution, whereas 13 patients died from pneumonitis. Increasing age (hazard ratio [HR], 1.04 per year; 95% confidence interval [CI], 1.00-1.08), and baseline shortness of breath increased pneumonitis risk (HR, 2.51; 95% CI, 1.13-5.55). Female sex (HR, 0.33; 95% CI, 0.15-0.70) and increasing platelet count (HR, 0.52 per log-unit increase; 95% CI, 0.30-0.92) decreased pneumonitis risk. In adjusted models, ICI-related pneumonitis significantly increased mortality (HR, 2.84; 95% CI, 1.84-4.37). CONCLUSIONS: ICI-related pneumonitis occurs at a high rate in AML patients and increases mortality. LAY SUMMARY: Immune checkpoint inhibitors (ICIs) remove inhibitory signals that reduce T-cell function and allow T-cells to better attack cancer cells. In acute myeloid leukemia (AML), the effectiveness of ICIs is limited in part by inflammation of the lung, called pneumonitis. This study reviewed 258 patients with AML who received ICIs and identified 30 patients who developed pneumonitis, nearly half of whom died. Older age and baseline shortness of breath increased pneumonitis risk, whereas female sex and higher baseline platelet counts decreased pneumonitis risk. Pneumonitis increased mortality by nearly 3-fold. This work highlights the significant harm imposed by pneumonitis after ICI therapies.
