The diagnostic value of homocysteine for the occurrence and acute progression of chronic obstructive pulmonary disease

Abstract Background This study aimed to evaluate whether the Homocysteine (Hcy) level was elevated in chronic obstructive pulmonary disease (COPD) patients and its correlation with the occurrence and acute progression of COPD. Methods From November 2014 to November 2015, COPD patients were enrolled from Beijing Chao-yang Hospital, and the the biological and clinical data were collected. These patients were tested in the non-acute exacerbation period and the acute exacerbation period, so they were defined as AECOPD group and Non-AECOPD group. Besides, 50 healthy subjects were recruited and defined as control group. Total plasma Hcy levels (antibodies-online, USA) were determined by enzyme-linked immunosorbent assay. Correlation analysis was used to analyze the correlation between serum Hcy level and ventilatory function. Using ROC curve, the diagnostic value of Hcy for the occurrence and acute progression of COPD was explored. Results In this study, we found that Hcy levels in the Non-AECOPD group or the AECOPD group were significantly higher than those in the control group (P < 0.001). Meanwhile, compared with the Non-AECOPD group, the Hcy level in the AECOPD group was significantly higher (P < 0.001). In addition, according to the classification of GOLD grade, there was significant difference in the Hcy level among different GOLD grade groups (P < 0.001). The correlation analysis showed that in the AECOPD group and the Non-AECOPD group, Hcy levels presented a negative correlation with FEV1(r < 0). Meanwhile, FEV1% was also negatively correlated with Hcy level (r < 0). ROC curve analysis showed that when the cutoff value was set to 10.8 μg/ml, the specificity, sensitivity and AUC were the best, which were 0.980, 0.800, and 0.945, respectively. Besides, our results showed that when the cutoff value was set to 14.0 μg / ml, the specificity, sensitivity and AUC were the best, which were 0.846, 0.680, and 0.802, respectively. In addition, compared with the prediction of acute progression of COPD, when Hcy level predicted the occurrence of COPD, its specificity (0.980 vs. 0.846, P < 0.001) and sensitivity (0.800 vs. 0.680, P < 0.001) were significantly higher. Conclusion Hcy level is positively correlated with the severity of COPD patients, which has predictive value for the occurrence of COPD and acute progression.

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.

Exacerbation Of Copd

Background: Chronic obstructive pulmonary disease (COPD) is characterized by pulmonary and systemic inflammatory processes, and exacerbation of COPD represents a critical moment in the progression of COPD. Several biomarkers of inflammation have been proposed to have a predictive function in acute exacerbation. However, their use is still limited in routine clinical practice. The purpose of our study is to explore the prognostic efficacy of novel inflammatory hemogram indexes in the exacerbation among stable COPD patients.Method: A total of 275 stable COPD patients from the Shanghai COPD Investigation Comorbidity Program were analyzed in our study. Blood examinations, especially ratio indexes like platelet–lymphocyte ratio (PLR), platelet × neutrophil/lymphocyte ratio [systemic immune-inflammation index (SII)], and monocyte × neutrophil/lymphocyte ratio [systemic inflammation response index (SIRI)], lung function test, CT scans, and questionnaires were performed at baseline and routine follow-ups. Clinical characteristics and information of exacerbations were collected every 6 months. The relationship between hemogram indexes and diverse degrees of exacerbation was assessed by logistic regression. The receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to evaluate the ability of hemogram indexes to predict exacerbation of COPD. Furthermore, the discrimination and accuracy of combined indexes were measured by ROC and calibration curve.Result: There was a significant positive correlation between PLR levels and total exacerbation of COPD patients in a stable stage in a year. Also, the predictive ability of PLR exceeded any other ratio indexes, with an AUC of 0.66. SII and SIRI ranked second only to PLR, with an AUC of 0.64. When combining PLR with other indexes (sex, COPD year, and St. George's Respiratory Questionnaire scores), they were considered as the most suitable panel of index to predict total exacerbation. Based on the result of the ROC curve and calibration curve, the combination shows optimal discrimination and accuracy to predict exacerbation events in COPD patients.Conclusion: The hemogram indexes PLR, SII, and SIRI were associated with COPD exacerbation. Moreover, the prediction capacity of exacerbation was significantly elevated after combining inflammatory hemogram index PLR with other indexes, which will make it a promisingly simple and effective marker to predict exacerbation in patients with stable COPD.

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.

Abstract Background: Analyze and compare the difference in arterial stiffness between patients with chronic obstructive pulmonary disease (COPD) and healthy people. Methods: A retrospective analysis of 83 patients with COPD who were treated the observation group; 80 healthy people were selected as the control group during the same period. Pearson correlation analysis software was used to analyze the correlation between arterial stiffness and ultrasound index in COPD patients. Results: The ultrasound RI and PI level of observation group were lower than those of control group and PI level (t=6.326, 8.321, P=0.000). Observation group IMT (1.36±0.13) mm, total plaque area (19.75±2.19) cm2, plaque number (1.67±0.64) were higher than control group IMT (0.94±0.10) mm, total plaque area (5.84±1.32) cm2, number of plaques (0.82±0.30) (t=4.574, 7.493, 5.093, P=0.000). The arterial stiffness (1585.49±14.36) cm/s and ABI level (1.63±0.24) of the observation group were higher than the arterial stiffness (1142.45±10.77) cm/s and ABI level (1.12±0.16) of the control group (t=6.392, 5.109, P=0.000). Arterial stiffness in COPD patients was negatively correlated with ABI, RI, PI levels (P<0.05); positively correlated with IMT, total plaque area, and plaque number (P<0.05). Conclusion The arterial stiffness of COPD patients is higher than that of healthy people; the ultrasound index can be used as an auxiliary indicator for clinical prediction of arterial stiffness, which is helpful to improve the accuracy of prediction and thus better guide clinical intervention in high-risk groups of COPD in time.

Background: Chronic obstructive pulmonary disease (COPD) is a chronic progressive obstructive airway disease which is often associated with cardiovascular diseases. Sympathetic dysfunction may complicate the cardiovascular diseases which may in turn increase the morbidity and mortality in COPD patients. Objective: Aim of this study was to evaluate sympathetic cardiovascular function status of COPD patients to reduce the cardiovascular complication in those patients. Methods: This comparative cross-sectional study was carried out at the department of Physiology and department of Medicine, Rajshahi Medical College, Rajshahi from July 2013 to June 2014. Results: A total number of 80 subjects aged 40-55 years were selected, among which 40 were clinically diagnosed COPD patients (case) and 40 were age, sex and BMI matched apparently healthy persons for comparison (control group). To observe sympathetic cardiovascular function status resting pulse rate, resting systolic BP, resting diastolic BP, decline of systolic BP in response to standing from lying position (orthostatic test) and rise of diastolic BP in response to sustained hand grip for 5 minutes (isometric exercise test) were measured. For statistical analysis Independent sample t-test, and Pearson’s correlation coefficient test were performed. In this study resting pulse rate, systolic BP, diastolic BP and rise of diastolic blood pressure in isometric exercise test were significantly increased in COPD than in healthy control group. On the other hand, decline of systolic blood pressure in orthostatic test was significantly decreased in COPD than in control group. Conclusion: This study concludes that sympathetic cardiovascular function is overactive in COPD and sympathetic over activity correlates with severity of the disease.
