Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) is a disease state characterized by airflow obstruction that is not fully reversible. The airflow obstruction is usually progressive and associated with an inflammatory response of the lungs to noxious particles and gases, often from smoking. COPD is the third leading cause of death in the United States, with both its prevalence and mortality continuing to increase. It has also become one of the leading causes of death and disability worldwide. COPD is estimated to affect more than 5% of the total population in the United States; approximately 5 million adults have emphysema and another 10 million have chronic bronchitis. This review covers the pathophysiology, stabilization and assessment, diagnosis and treatment, and disposition and outcomes of COPD. Figures show spirometry test results in a normal patient and a patient with severe COPD, stages of COPD according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD), the pathogenesis of emphysema from smoking, pathologic lesions in small airways in a patient with COPD, the acinar structure of normal lungs compared with that of lungs in patients with centriacinar (centrilobular) emphysema or panacinar (panlobular) emphysema, and electrocardiogram demonstrating findings consistent with P pulmonale and right heart strain due to advanced COPD. Tables list pathogenic mechanisms of COPD, pathophysiology of a COPD exacerbation, bacterial pathogens in acute COPD exacerbations, key historical features of COPD, differential diagnosis of patients presenting with possible COPD, criteria for hospitalization as indicated by GOLD guidelines, and indications for ICU admission.

BACKGROUND: Targeted spirometry screening for chronic obstructive pulmonary disease (COPD) has been studied in primary care and community settings. Limitations regarding availability and quality of testing remain. A targeted spirometry screening program was implemented within a presurgical screening (PSS) clinic to detect undiagnosed airways disease and identify patients with COPD/asthma in need of treatment optimization.OBJECTIVE: The present quality assurance study evaluated airflow obstruction detection rates and examined characteristics of patients identified through the targeted screening program.METHODS: The targeted spirometry screening program was implemented within the PSS clinic of a tertiary care university hospital. Current or ex-smokers with respiratory symptoms and patients with a history of COPD or asthma underwent prebronchodilator spirometry. History of airways disease and smoking status were obtained during the PSS assessment and confirmed through chart reviews.RESULTS: After exclusions, the study sample included 449 current or ex-smokers. Abnormal spirometry results were found in 184 (41%) patients: 73 (16%) had mild, 93 (21%) had moderate and 18 (4%) had severe or very severe airflow obstruction. One hundred eighteen (26%) new cases of airflow obstruction suggestive of COPD were detected. One-half of these new cases had moderate or severe airflow obstruction. Only 34% of patients with abnormal spirometry results had reported a previous diagnosis of COPD. More than one-half of patients with abnormal spirometry results were current smokers.CONCLUSIONS: Undiagnosed airflow obstruction was detected in a significant number of smokers and ex-smokers through a targeted screening program within a PSS clinic. These patients can be referred for early intervention and secondary preventive strategies.

Chronic Obstructive Pulmonary Disease (COPD) is a lung disease characterized by chronic obstruction of lung airflow that interferes with normal breathing, which is progressive and is not fully reversible. COPD includes chronic bronchitis and emphysema. Symptoms of COPD are well explained in Ayurveda in the context of Kasa and Swasa among which chronic bronchitis can be better correlated to Vataja and Kaphaja kasa and emphysema to Tamaka swasa. COPD is characterized by mucous hyper secretion, airway narrowing, fibrosis and destruction of lung parenchyma. Even though the existing conventional management is excellent, Ayurveda provides additional benefits such as improvement in quality of life. The study drug Hareetakyadi yoga is mentioned in Prakarana of kasa in Chikitsa manjari. The objective of the study was to evaluate the Effect of Hareetakyadi yoga in Chronic Obstructive Pulmonary Disease. The Study includes 10 subjects of age group 40-70 years of both gender, diagnosed clinically and as per investigations satisfying COPD, stage 1 & 2 as per GOLD criteria of spirometry attending department of Kayachikitsa, Government Ayurveda College, Thiruvananthapuram. A protocol from Deepana to Virechana were done as preparatory phase before administering drug. Hareetakyadi yoga having the properties of Kapha vata hara, Agni deepana and Rasayana property seems to be effective in the management of this disease.

Background and aims: Fatigue is associated with longitudinal ratings of health in patients with chronic obstructive pulmonary disease (COPD). Although the degree of airflow obstruction is often used to grade disease severity in patients with COPD, multidimensional grading systems have recently been developed. The aim of this study was to investigate the relationship between perceived and actual fatigue level and multidimensional disease severity in patients with COPD. Materials and methods: Twenty-two patients with COPD (aged 52-74 years) took part in the study. Multidimensional disease severity was measured using the SAFE and BODE indices. Perceived fatigue was assessed using the Fatigue Severity Scale (FSS) and the Fatigue Impact Scale (FIS). Peripheral muscle endurance was evaluated using the number of sit-ups, squats, and modified push-ups that each patient could do. Results: Thirteen patients (59%) had severe fatigue, and their St George’s Respiratory Questionnaire scores were significantly higher (p < 0.05). The SAFE index score was significantly correlated with the number of sit-ups, number of squats, FSS score and FIS score (p < 0.05). The BODE index was signif- icantly associated with the numbers of sit-ups, squats and modified push-ups, and with the FSS and FIS scores (p < 0.05). Conclusions: Peripheral muscle endurance and fatigue perception in patients with COPD was related to multidimensional disease severity measured with both the SAFE and BODE indices. Improvements in perceived and actual fatigue levels may positively affect multidimensional disease severity and health status in COPD patients. Further research is needed to investigate the effects of fatigue perception and exercise training on patients with different stages of multidimensional COPD severity.

Chronic obstructive pulmonary disease (COPD) is defined as persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases. It has been suggested that emotional disturbances such as depression and anxiety are common among patients with COPD. This review aims to highlight the presence of depression and associated risk factors among patients suffering from COPD in Asia. Fifty-eight observational studies were retrieved through data sources like PubMed, Medical subject heading (MeSH) search and Google scholar. After thorough screening total thirteen studies were identified and included in this review. Based on the results of these studies, the south and west Asian countries had higher proportion of depression. However, risk factor results were mixed which includes severity of obstruction/global initiative for obstructive lung disease (GOLD) criteria, Stage 2 COPD, teetotallers, smoking, alcohol consumption, body mass index, airflow obstruction, dyspnoea, and exercise (BODE) index, urban residence, female gender, education level, dyspnoea, low income, poor Quality of life (QOL) scores, age, poor self-reported health, basic activity of daily living (BADL) disability. Further superior research studies with larger sample size are required on Asian population. All in all, it is recommended that early diagnosis and treatment of depression should be included as a part of management in COPD as it can help to minimize the risk of morbidity and mortality in the patients.
