The Mean

This study aimed to review and critically appraise the current methodological issues undermining the suitability of the measurement of serum/plasma glutathione, both in the total and reduced form, as a measure of systemic oxidative stress in chronic obstructive pulmonary disease (COPD). Fourteen relevant articles published between 2001 and 2020, in 2003 subjects, 1111 COPD patients, and 892 controls, were reviewed. Nine studies, in 902 COPD patients and 660 controls, measured glutathione (GSH) in the reduced form (rGSH), while the remaining five, in 209 COPD patients and 232 controls, measured total GSH (tGSH). In the control group, tGSH ranged between 5.7 and 7.5 µmol/L, whilst in COPD patients, it ranged between 4.5 and 7.4 µmol/L. The mean tGSH was 6.6 ± 0.9 µmol/L in controls and 5.9 ± 1.4 µmol/L in patients. The concentrations of rGSH in the control group showed a wide range, between 0.47 and 415 µmol/L, and a mean value of 71.9 ± 143.1 µmol/L. Similarly, the concentrations of rGSH in COPD patients ranged between 0.49 and 279 µmol/L, with a mean value of 49.9 ± 95.9 µmol/L. Pooled tGSH concentrations were not significantly different between patients and controls (standard mean difference (SMD) = −1.92, 95% CI −1582 to 0.0219; p = 0.057). Depending on whether the mean concentrations of rGSH in controls were within the accepted normal range of 0.5–5.0 µmol/L, pooled rGSH concentrations showed either a significant (SMD = −3.8, 95% CI −2.266 to −0.709; p < 0.0001) or nonsignificant (SMD = −0.712, 95% CI −0.627 to 0.293; p = 0.48) difference. These results illustrate the existing and largely unaddressed methodological issues in the interpretation of the serum/plasma concentrations of tGSH and rGSH in COPD.

The aim of this study was to evaluate the serum level of total cholesterol, triglycerides (TG), low density lipoproteins (LDL) and high density lipoproteins, (HDL) in chronic obstructive pulmonary disease (COPD) patients admitted in National Institute of Disease of Chest and Hospital, Mohakhali, Dhaka during. January 2009 to January 2010. Twenty two patients with COPD and 22 healthy controls were included in this study. Total cholesterol, HDL and TG levels were determined with ILAB 1800 Chemistry Analyzer using ILAB test Reagents. LDL concentration was calculated using the Friedewald Equation. The mean level of TG was 150.04±29.66 mg/dl and 126.14±13.28 in COPD patients and healthy control, respectively. A statistically significant difference was found between the two groups (p<0.001). The mean level of TC was 181.83±20.11 mg/dl and 176.28±15.35 mg/dl in COPD patients and healthy control respectively (p<0.001). LDL level mean value was 116.12±14.26 mg/dl and 108.95±10.39 in COPD patients and control respectively (p<0.001). The mean value of HDL showed 38.79±2.4 in COPD patients and 39.014±1.56 in control. A statistically significance was also found between the two groups (p<0.001). Our results showed that the values of TC, TG, LDL were higher than healthy control that is highly significant statistically. On the other hand, the was significantly decreased HDL level compared with controls. DOI: http://dx.doi.org/10.3329/bjmb.v3i2.13810 Bangladesh J Med Biochem 2010; 3(2): 42-45

Introduction The oral cavity and pharynx have a rich sensory system composed of specialized receptors. The integrity of oropharyngeal sensation is thought to be fundamental for safe and efficient swallowing. Chronic obstructive pulmonary disease (COPD) patients are at risk for oropharyngeal sensory impairment due to frequent use of inhaled medications and comorbidities including gastroesophageal reflux disease. Objective This study aimed to describe and compare oral and oropharyngeal sensory function measured using noninstrumental clinical methods in adults with COPD and healthy controls. Method Participants included 27 adults (18 men, nine women) with a diagnosis of COPD and a mean age of 66.56 years ( SD = 8.68). The control group comprised 11 healthy adults (five men, six women) with a mean age of 60.09 years ( SD = 11.57). Spirometry measures confirmed reduced functional expiratory volumes (% predicted) in the COPD patients compared to the control participants. All participants completed a case history interview and underwent clinical evaluation of oral and oropharyngeal sensation by a speech-language pathologist. The sensory evaluation explored the detection of tactile and temperature stimuli delivered by cotton swab to six locations in the oral cavity and two in the oropharynx as well as identification of the taste of stimuli administered in 5-ml boluses to the mouth. Analyses explored the frequencies of accurate responses regarding stimulus location, temperature and taste between groups, and between age groups (“≤ 65 years” and “> 65 years”) within the COPD cohort. Results We found significantly higher frequencies of reported use of inhaled medications ( p < .001) and xerostomia ( p = .003) in the COPD cohort. Oral cavity thermal sensation ( p = .009) was reduced in the COPD participants, and a significant age-related decline in gustatory sensation was found in the COPD group ( p = .018). Conclusion This study found that most of the measures of oral and oropharyngeal sensation remained intact in the COPD group. Oral thermal sensation was impaired in individuals with COPD, and reduced gustatory sensation was observed in the older COPD participants. Possible links between these results and the use of inhaled medication by individuals with COPD are discussed.

Background: Chronic Obstructive Pulmonary Disease (COPD) leads to limited activity and reduced quality of life. Treatment of this disease is a long-term process that requires the cooperation of patients in monitoring and treatment. Methods: In the present study which was conducted from April 2019 to March 2021 in Masih Daneshvari Hospital, Tehran, Iran, 75 patients were randomly divided into telerehabilitation and control groups. Patients in the control group received pulmonary rehabilitation including respiratory, isometric, and aerobic exercises for 8 weeks, three times per week. In the second group, patients were given a lung rehabilitation booklet and asked to repeat the exercises three times a week for four weeks according to a specific schedule. In addition, patients installed Behzee care application on the mobile phone that recorded various indicators such as heart rate, SpO2, dyspnea, fatigue, and daily activities. This application reminded the patient of the program every day and at a specific time. Finally, the patients’ conditions were compared in the two groups after 8 weeks using CAT and mMRC questionnaires and 6-Minute Walk (6MW) exercise indices as well as spirometry tests. Results: In all four indicators (6MW, CAT,  and mMRC questionnaires as well as spirometry), patients showed improvement after rehabilitation (p<0.001). This improvement was significantly higher in the telemedicine group compared to the other group (p<0.01). Conclusion: The use of telerehabilitation in COPD patients is effective in improving spirometry indices, quality of life, as well as activity and sports indices.

Introduction: Chronic obstructive pulmonary disease (COPD) is the leading cause of morbidity and mortality worldwide. Cigarette smoke and noxious agent result in oxidative stress and activate release of inflammatory mediators such as Interleukin-8 (IL-8). Quercetin is a flavonoid compound containing anti-inflammatory effects which can be used as an adjuvant therapy in stable COPD. Objective: To analyze the effect of quercetin on serum IL-8 levels, % VEP1, and CAT score of stable COPD patients. Methods: Experimental clinical trial with pre-test and pasca-test design was performed in 30 patients with stable COPD in Dr. Moewardi Surakarta between December 2017 and January 2018. The samples taken by using purposive sampling were divided into two groups treatment groups received standard therapy and quercetin 500mg/day for 28 days and control groups only received standard therapy. The decrease in inflammation was measured by serum IL-8 examination, improvement of obstruction measured by %FEV1 and clinical improvement measured by CAT score. Results: IL-8 serum level was significantly lower in treatment group than of in control group (p=0,001). The percentage of FEV1 was insignificant different between the two group (p=0,236). However CAT score was significantly lower in treatment group compared to that of in control group (p=0,001) Conclusions: Quercetin can decrease IL-8 serum level and decrease CAT score when given in combination with standard therapy for COPD patients.

Abstract Background: Prevalence and impact of chronic rhinosinusitis (CRS) in chronic obstructive pulmonary disease (COPD) remain unclear. We hypothesized that CRS is more frequent in patients with COPD compared to controls and we aimed to evaluate the odds of CRS in both groups. Methods: We recruited patients with COPD and a healthy control group in a tertiary referral hospital in Switzerland. Diagnosis of CRS was defined according to published guidelines and supported by computed tomography (CT) findings. Sino-nasal-outcome-test-20 (SNOT-20) and sino-nasal-outcome-test-primary-nasal-symptom-score (SNOT-PNS-score) were self-assessed with a cut-off for abnormality of >12. Results: Data from 83 COPD patients (35 females, age: 67 years ± 10) and 34 controls (18 females, age: 67 years ± 12) were analyzed. In the COPD group 14 out of 83 (20.3%) fulfilled the diagnosis of CRS compared to only 1 out of 34 (3%) in the control group (OR 6.7; 95% CI 0.84-53.10; p = 0.064). Forty-eight COPD patients (59%) and 14 controls (41%) had an abnormal SNOT-20 score (OR 1.96; 95% CI 0.87-4.40; p=0.10), with a median score of 16.0 (ICR 21) in COPD patients compared to a median score of 8.0 (ICR 13) in controls (p=0.001). The SNOT-PNS-score was abnormal in 49 COPD patients (59%) and in 9 controls (26%) (OR 4.00; 95% CI 1.66-9.64; p=0.001). Abnormal findings of the upper airways did not correlate with COPD severity or smoking status. Conclusions: CRS was a frequent diagnosis in patients with COPD. CRS reduces quality of life in this patient group.

Objective:To evaluate the prevalence of restless legs syndrome (RLS) in patients with chronic obstructive pulmonary disease (COPD) and the relationship between RLS and clinical/laboratory findings of COPD.Methods:One hundred and thirty-four COPD patients without secondary causes of RLS were included. Thirty-nine (29.1%) patients were diagnosed with RLS and classified as Group 1. The control group consisted of 65 age-matched COPD patients without RLS. Group 1 was divided into subgroups according to the Johns Hopkins Severity (JHS) scale. Patients with a score of 0, 1, or 2 were classified as JHS 0-2 and those with a score of 3 as JHS 3. Group 1 and the control group and subgroups were compared for clinical and laboratory characteristics.Results:We found that the duration of COPD was longer and that airway obstruction, hypercapnia, and hypoxia were more evident in patients with RLS than those without. Similar differences were also detected between JHS subgroups 3 (more severe) and 0-2. Polyneuropathy frequency was significantly higher in Group 1 compared to controls. However, Group 1 subgroups showed a similar frequency of polyneuropathy. In a multivariate analysis, hypercapnia made a significant independent contribution to both JHS 0-2 and JHS 3 patients when RLS severity was set as the dependent variable. Polyneuropathy and the duration of COPD were significant independent variables for patients in the JHS 3 subgroup. Polyneuropathy was the strongest predictor for the JHS 3 patients.Conclusions:We conclude that RLS is frequent in COPD, particularly in patients with severe hypoxemia/hypercapnia and in late stages of the disease.

Objectives: To evaluate the outcomes of clinical pharmacist-led medication therapy management (MTM) services for patients with chronic obstructive pulmonary disease (COPD). Methods: Two hundred COPD patients admitted by the Department of Respiratory and Critical Care Medicine of Baoding No.1 Central Hospital during January 2019 and December 2020 were randomly assigned to a control group (n =100) and an experimental group (n =100). Patients in the control group received conventional treatment, while those in the experimental group were provided with MTM services based on the conventional treatment for comparative analysis of outcome measures, including use of antibacterials during hospital stay, length of stay (LoS), costs of hospitalization (CoH), cases of adverse drug reactions (ADRs), and medication adherence (MA) and COPD assessment test (CAT) score one and six months after discharge. Results: Compared with the control group, the experimental group had reduced use of antibacterials during hospital stay, LoS, CoH, and ADR rate (P <0.05). After discharge, patients in both groups showed remarkable improvements in MA and CAT scores in comparison with their performances upon admission, and the experimental group exhibited better MA and higher CAT score than the control group, with the differences indicating statistical significance (P <0.05). Conclusion: MTM designed for COPD patients can improve pharmacist-led service quality and clinical outcomes of COPD. doi: https://doi.org/10.12669/pjms.37.7.4518 How to cite this:Liu M, Liu J, Geng Z, Bai S.

Objective. To compare frequency of echocardiographic changes in patients with chronic obstructive pulmonary disease (COPD) and non-COPD controls and to assess their relation to the level of airflow limitation. Methods. Study population included 120 subjects divided in two groups. Group 1 included 60 patients with COPD (52 male and 8 female, aged 40 to 80 years) initially diagnosed according to the actual recommendations. Group 2 included 60 subjects in whom COPD was excluded serving as a control. The study protocol consisted of completion of a questionnaire , pulmonary evaluation (dyspnea severity assessment, baseline and post-bronchodilator spirometry, gas analyses, and chest X-ray) and two dimensional (2D) Doppler echocardiography. Results. We found significantly higher mean right ventricle end-diastolic dimension (RVEDd) in COPD patients as compared to its dimension in controls (28.0 ± 4.8 vs. 24.4 ± 4.3; P = 0.0000). Pulmonary hypertension (PH) was more frequent in COPD patients than in controls (28.0 ± 4.8 vs. 24.4 ± 4.3; P = 0.0000) showing linear relationship with severity of airflow limitation. The mean value of left ventricular ejection fraction (LVEF%) was significantly lower in COPD patients than its mean value in controls (57.4 ± 6.9% vs. 64.8 ± 2.7; P = 0.0000) with no correlation with severity of airflow limitation.       Conclusion. Frequency of echocardiographic changes in COPD patients was significantly higher as compared to their frequency in controls in the most cases being significantly associated with severity of airflow limitation. Echocardiography enables early, noninvasive, and accurate diagnosis of cardiac changes in COPD patients giving time for early intervention. Key words: airflow limitation, chronic obstructive pulmonary disease, Doppler echocardiography, pulmonary hypertension, ventricular dysfunction.

Background Pulmonary rehabilitation is one of the main interventions to reduce the use of health resources, and it promotes a reduction in chronic obstructive pulmonary disease (COPD) costs. mHealth systems in COPD aim to improve adherence to maintenance programs after pulmonary rehabilitation by promoting the change in attitude and behavior necessary for patient involvement in the management of the disease. Objective This study aimed to assess the effects of an integrated care plan based on an mHealth web-based platform (HappyAir) on adherence to a 1-year maintenance program applied after pulmonary rehabilitation in COPD patients. Methods COPD patients from three hospitals were randomized to a control group or an intervention group (HappyAir group). Patients from both groups received an 8-week program of pulmonary rehabilitation and educational sessions about their illness. After completion of the process, only the HappyAir group completed an integrated care plan for 10 months, supervised by an mHealth system and therapeutic educator. The control group only underwent the scheduled check-ups. Adherence to the program was rated using a respiratory physiotherapy adherence self-report (CAP FISIO) questionnaire. Other variables analyzed were adherence to physical activity (Morisky-Green Test), quality of life (Chronic Obstructive Pulmonary Disease Assessment Test, St. George’s Respiratory Questionnaire, and EuroQOL-5D), exercise capacity (6-Minute Walk Test), and lung function. Results In total, 44 patients were recruited and randomized in the control group (n=24) and HappyAir group (n=20). Eight patients dropped out for various reasons. The CAP FISIO questionnaire results showed an improvement in adherence during follow-up period for the HappyAir group, which was statistically different compared with the control group at 12 months (56.1 [SD 4.0] vs 44.0 [SD 13.6]; P=.004) after pulmonary rehabilitation. Conclusions mHealth systems designed for COPD patients improve adherence to maintenance programs as long as they are accompanied by disease awareness and patient involvement in management.

The Mean

Patients’ with Chronic Obstructive Pulmonary Disease suffer from serious respiratory symptoms that increase anxiety, stress, and uncertainty, and affect quality of life. The aim of this study was to assess level of anxiety, uncertainty, and health related quality of life (HRQoL) among COPD patients in Jordan. Correlational cross-sectional survey design was used to collect data from 153 COPD patients. ‎The study was conducted at pulmonary clinics in three major referral hospitals in Jordan that provide care for COPD patients from different parts of the country. To assess HRQoL, St. George ‎Respiratory Questionnaire‎ was completed. Uncertainty and anxiety level was measured by Mishel's uncertainty of illness scale and state anxiety inventory respectively. The mean age of participants was 66.8 (SD= 10.3) and most participants were males (94.1%) with. The mean score of HRQoL was 57.9 (SD = 20.5). The mean score of participants’ level of anxiety was 38.1 (SD = 11.1). The mean score of uncertainty was 66.1 (SD= 11.1). There is a statistically significant positive relationship between HRQoL and anxiety (r =.433, p< .01), and uncertainty (r=.483, p<.01). Increased anxiety and uncertainty among COPD patients was associated with low HRQoL. Health care providers need to pay attention the effect of anxiety and uncertainty on COPD patients’ quality of life and institute appropriate management.
