Copd treatment

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) may experience acute mountain sickness (AMS) and other altitude-related adverse health effects (ARAHE) when travelling to high altitude. We evaluated whether dexamethasone, a drug used for AMS prevention in healthy individuals, would prevent AMS/ARAHE in COPD. METHODS: In this placebo-controlled, double-blind, parallel-design trial COPD patients, GOLD grade 1-2, living below 800m, were randomized to receive dexamethasone (8mg/day) or placebo starting on the day before ascent and while staying in a high altitude clinic at 3100m for 2 days...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a multicomponent disorder characterized by inflammation, representing a significant leading cause of chronic morbidity and mortality. Reports have implicated hydrogen sulfide (H2 S) in both the pathology and treatment of COPD. The present study aimed to explore the effects involved with exogenous H2 S on endoplasmic reticulum stress (ERS) and pulmonary artery endothelial cells (PAECs) in a rat model of COPD. METHODS: Rat models of COPD were successfully established by means of passive smoke exposure and intratracheal injection with lipopolysaccharide (LPS)...

Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are a major complication in COPD patients which can be triggered by bacterial or viral infections, environmental pollutants and other causes. Procalcitonin (PCT), a peptide that markedly increases in cases of bacterial infection, has been extensively investigated as a biomarker in the diagnosis, prognosis and treatment in patients with AECOPD. A number of studies published in the last decade, tried to investigate whether PCT levels can differentiate between bacterial and other causes of exacerbations, if they can be used as a guide for optimal antibiotic therapy and if they can be a tool in the assessment of the severity and the need for further interventions in the management of those patients...

Acute exacerbations in chronic obstructive pulmonary disease (AECOPD) are associated with increased mortality, rate of hospitalization, use of healthcare resources, and have a negative impact on disease progression, quality of life and lung function of patients with chronic obstructive pulmonary disease (COPD). There is an imperative need to homogenize the definition of AECOPD because the incidence of exacerbations has a significant influence or implication on treatment decision making, particularly in pharmacotherapy and could impact the outcome or change the statistical significance of a therapeutic intervention in clinical trials...

Physical activity (PA) is defined as bodily movement produced by skeletal muscles with energy expenditure beyond resting levels. PA is closely related to reduced morbidity and mortality in chronic obstructive pulmonary disease (COPD). Self-report questionnaires are often subject to recall bias, correlating poorly with objectively qualified PA, and do not provide an accurate estimate of free-living energy expenditure. PA may be objectively evaluated by newly developed tri-axial accelerometers by quantifying steps or body movements over a period of time...

RATIONALE: Laparoscopic totally extraperitoneal (TEP) inguinal hernia repair is a rapidly evolving, minimally invasive treatment modality for inguinal hernia. Compared with open hernia repair, this method requires a smaller incision, has cosmetic advantages, and facilitates rapid recovery and early return to daily activities because of less postoperative pain. Because general anesthesia is essential for TEP hernia repair, it cannot be performed on patients who have an increased risk of developing complications when placed under general anesthesia...

To investigate the effect of stimulation of Human Bronchial Epithelial Cells (HBEC) by arterial traffic ambient PM2.5 (TAPM2.5) and wood smoke PM2.5 (WSPM2.5) on the expression of lncRNAs in order to find new therapeutic targets for treatment of chronic obstructive pulmonary disease (COPD). HBECs were exposed to TAPM2.5 and WSPM2.5 at a series of concentrations. The microarray analysis was used to detect the lncRNA and mRNA expression profiles. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and gene ontology (GO) enrichment were conducted to analyze the differentially expressed lncRNAs and mRNAs...

Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous disease, and there is a clinical need for validated markers and biomarkers that can contribute to the assessment of patients, risk prediction, treatment guidance, and assessment of response. Although according to the 2018 GOLD guidelines clinically useful biomarkers for COPD patients in stable condition have yet to be identified, several clinical markers and biomarkers have been proposed for COPD. These include isolated clinical markers, such as symptoms and Health Status assessment, exercise tests, function tests and imaging, and also composite scores and molecular markers...

BACKGROUND: Any acute event, either primary or secondary to a chronic disease, is generally followed by some degree of physical impairment. The Sub-Acute Care (SAC) represents one of the inpatient intermediate care settings aimed at completing recovery and restoring functional capacity. Debate exists on the role of the rehabilitation treatment in the SAC setting. AIM: To compare the outcomes of patients managed in two different SAC Units where A) patients undergo an individualized rehabilitation program on top of optimal medical therapy (OMT) B) patients receive OMT only...

The employment of systemic corticosteroids in the treatment of acute exacerbations of chronic obstructive pulmonary disease (COPD) has been shown to improve airway limitation, decrease treatment failure and risk of relapse, and may improve symptoms in addition to decreasing the length of hospital stay. Nowadays, all clinical guidelines recommend systemic corticosteroids to treat moderate or severe COPD exacerbations. However, their use is associated with potential side effects, mainly hyperglycemia. In the era of precision medicine, the possibility of employing blood eosinophil count has emerged as a potential way of optimizing therapy...

Chronic obstructive pulmonary disease (COPD) is a growing cause of morbidity and mortality worldwide. Cigarette smoke (CS) exposure, a major cause of COPD, dysregulates airway epithelial ion transport and diminishes airway surface liquid (ASL) volume. Short palate lung and nasal epithelial clone 1 (SPLUNC1) is secreted into the airway lumen where it maintains airway hydration via interactions with the epithelial Na+ channel (ENaC). Although ASL hydration is dysregulated in CS-exposed/COPD airways, effects of CS on SPLUNC1 have not been elucidated...

Patients with Chronic Obstructive Pulmonary Disease (COPD) and / or Obstructive Sleep Apnea (OSA) often complain about sleepiness, fatigue, anxiety and depression. However, common screening questionnaires, like Epworth Sleepiness Scale (ESS), Fatigue Severity Scale (FSS) and Hospital Anxiety and Depression Scale (HADS) have not been previous evaluated in patients with overlap-coexisting COPD and OSA-syndrome versus patients with OSA alone. Our study compared ESS, FSS and HADS between patients with overlap syndrome and patients with OSA, before and after treatment with Continuous Positive Airways Pressure (CPAP)...

OBJECTIVE: To observe the immunoregulatory effect of electroacupuncture (EA) intervention for muscular dystrophy chronic obstructive pulmonary disease (COPD) rats, so as to investigate its underlying mechanism in improving respiratory function. METHODS: Forty male SD rats were randomly divided into 5 groups: normal, model, EA, exercise, and EA+ exercise ( n =8 in each). The muscular dystrophy COPD model was established by placing the rats in a closed box to be exposed to cigarette smoke (3-10 cigarettes/time) for 60 min, twice daily, 6 days a week for 90 days...

Objective: This study aimed to evaluate the efficacy and safety of acupuncture therapy (AT) for improving functional effects and quality of life in COPD patients. Methods: PubMed, Embase, Cochrane Library, Web of Science, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Chongqing VIP (CQVIP), and Wanfang Data were searched. The randomized controlled trials (RCTs) evaluating the effect of AT on COPD patients were included...

BACKGROUND: Exacerbations of COPD (ECOPD) are important events in the course of COPD and they accelerate the rate of decline of lung function, and exacerbations requiring hospitalization are associated with significant mortality. Therefore, developing approaches of prevention and early treatment of ECOPDs are of special clinical interests. One of such approaches is telecare, including home telemonitoring. MATERIAL AND METHODS: Daily telemonitoring of HR, BP, SpO2 and spirometry was performed...

Objective: To explore the remodeling of pulmonary arterioles in chronic obstructive pulmonary disease (COPD), and its effect on hemorheology of proximal pulmonary arteries, right ventricular structure and function , and the potential mechanisms. Method: A total of 34 patients undergoing surgical treatment for lung tumors admitted to the General Hospital of Ningxia Medical University were included in the study. According to the preoperative lung function, there were 15 patients with COPD complicated with lung tumor (COPD group) and 19 patients with normal pulmonary function with lung tumor (control group)...

The diagnosis and treatment of chronic obstructive pulmonary disease (COPD) has been based largely on a one-size-fits-all approach. Diagnosis of COPD is based on meeting the physiologic criteria of fixed obstruction in forced expiratory flows and treatment focus on symptomatic relief, with limited effect on overall prognosis. However, patients with COPD have distinct features that determine very different evolutions of the disease. In this review we highlight distinct subgroups of COPD characterized by unique pathophysiologic derangements, response to treatment, and disease progression...

COPD is the third leading cause of death in the United States, with current rates of both morbidity and mortality persisting and contributing significantly to long-term disability. More than 11 million Americans are diagnosed with COPD, with an additional 13 million people estimated to be living with undiagnosed disease. For patients diagnosed with COPD, the turning point will be hospitalization. It is important, therefore, that new treatment techniques that manage the signs and symptoms of the COPD and impact the prevalence and severity of exacerbations, hospital admissions, quality of life, and activities of daily living, and innovative clinical management strategies that optimize hospital discharge planning, all show promise in improving outcomes for patients with COPD...

RATIONALE: The standard of care for patients with acute respiratory distress syndrome (ARDS) has been developed based on studies that usually excluded patients with major comorbidities. OBJECTIVES: To describe treatments and outcomes according to comorbidities in patients with ARDS admitted to 19 ICUs (1997-2014). METHODS: Patients were grouped based on comorbidities. Determinants of day-28 mortality were identified by multivariable Cox analysis stratified on center...

Inhaled corticosteroids are widely used in the treatment of chronic obstructive pulmonary disease (COPD). However, their use has been questioned for appropriate dose and a possible increased risk of pneumonia. Here, we reviewed patients with COPD who had received fluticasone-salmeterol combination treatment using data from a linked electronic medical record database. A total of 180 patients received salmeterol with 250 µg fluticasone propionate twice daily and 78 received salmeterol and 100 µg fluticasone propionate twice daily...
