Body mass index, obstruction of the airflow, dyspnea, and exercise capacity index as predictor of the severity of exacerbations and systemic involvement in patients with COPD

Background: Allocation of the limited resources to the needed patients and decision making regarding timely interventions demand development of a reliable, cost effective, simple assessment tool. Several studies propose body-mass index, airflow obstruction, dyspnea, and exercise (BODE) index for this purpose in patients with Chronic obstructive pulmonary disease (COPD). The objective of this study was to assess the utility of BODE index to predict the severity of exacerbations and systemic involvement in COPD.Methods: A Present hospital based cross sectional study was carried out among 100 COPD patients. BODE index was used to assess the patients and its association was studied with various variables. The data was analyzed using one-way analysis of variance (ANOVA) test.Results: As the body index class of severity increases, the number of hospitalizations required in the past also increases and this association is statistically significant. As the severity of the disease increased as indicated by the class the mean number of exacerbations in the past increased and this association was found out to be statistically significant. As the severity of the disease increased as indicated by the class level, the mean number of days of hospitalization increased. But this increase was of small difference and hence on one-way ANOVA test was not found out to be statistically significant. As the pack years increases, the BODE index increases significantly (p value <0.001). As the severity of the disease increased, the mean body mass index decreased. Haemoglobin level was found to decrease with increase in BODE index class of severity. This association was statistically significant.Conclusions: The BODE index has been found to be a very good tool to assess the prognosis of COPD as well as severity of acute exacerbations.

The Relation of COPD Assessment Test (CAT) and BODE Index in Assessing Patients with COPD: Is Cat Alone Simple and Good Enough?

Chronic obstructive pulmonary disease (COPD) is a significant cause of disability and death worldwide. It is often evaluated with outcome measures like lung function test (LFT), health status and BODE (Body mass, Obstruction, Dyspnoea and Exercise capacity) index, to initiate appropriate treatment. Objectives: To determine the association between the BODE index and COPD assessment test (CAT) in COPD patients. To ascertain the utility of CAT alone as an assessment tool for COPD patients in primary care setting and low resource countries. Methods: A cross-sectional study of sixty (60) patients with clinical and lung function test diagnosis of COPD were recruited consecutively from the outpatient clinic. The body mass index (BMI) of the patients, CAT scores, modified medical research council dyspnoea scale and sixminute walk distance test (6MWDT) was assessed and recorded. The individual score was summed up to obtain the BODE index score for the particular patients. Results: The mean age was 68.8years (± 10.3). There was a strong correlation between the BODE index and CAT scores (r= 0.77 P <0.0001). Inter-rater agreement between the tools (CAT and BODE index) was moderate (k=0.46). The CAT questionnaire also correlated well with the modified medical research council dyspnea scale, the six-minute walk test and the forced expiratory volume in the first second. Conclusion: CAT can serve as a simple, easy to administer tool for the assessment of patients with COPD especially in low resource countries and primary care setting.

A Descriptive Study of Chronic Obstructive Pulmonary Disease in Tertiary Care Clinics of a Caribbean Island / Estudio descriptivo de la enfermedad pulmonar obstructiva crónica en clínicas de atención terciaria de una isla caribeña

ABSTRACT Objective: To determine the relationship between severity of chronic obstructive pulmonary disease (COPD) and quality of life as well as COPD's correlation with depressive symptoms in West Indian subjects. Methods: This is a cross-sectional, observational study of outpatients with COPD in tertiary care. The severity of COPD was determined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage, GOLD group, and body mass index, airflow obstruction, dyspnoea and exercise capacity (BODE) index. Quality of life was assessed by the St George Respiratory Questionnaire (SGRQ) and COPD Assessment Test (CAT), and depression was assessed by the Center for Epidemiologic Studies Depression Scale (CES-D). Results: A total of 105 patients (85.7% male, 37.1% Indo-Trinidadian, 42.9% Afro-Trinidadian, 64.8% primary level education) were recruited with a mean age of 66.9 years (standard deviation: 9.60 years). The median body mass index was 25 kg/m2; 26.7% were underweight. Risk factors identified were: ever-smokers (27.6%), marijuana (20%), biomass (81.9%), passive smoke (70.5%), occupational exposures (80%). The CES-D of 25% of the patients was ≥16. Co-morbidities included diabetes (22%), hypertension (29%), gastro-oesophageal reflux disease (10%) and previous myocardial infarction (15%). A total of 59% of the patients reported a monthly household income of less than US$800. Lower level of education was associated with worse SGRQ (total and impact), lower forced expiratory volume in one second, modified Medical Research Council scale (mMRC) of ≥ 2 and higher BODE index. Higher GOLD group correlated with worse SGRQ, CAT and CES-D. Higher CES-D was associated with shorter six-minute walk distance, worse SGRQ, CAT and mMRC scores, higher GOLD group and increased COPD admissions per year. Patients with a CES-D of ≥ 16 walked shorter distances. Higher BODE quartile was associated with worse SGRQ, CAT and CES-D scores. Conclusion: Higher GOLD group and higher BODE quartile were associated with worse quality of life scores and higher depression scores. Patients in higher GOLD groups should be screened for depression. Education on COPD should be targeted at those of lower socioeconomic status.

RESUMEN Objetivo: Determinar la relación entre la severidad de la enfermedad pulmonar obstructiva crónica (EPOC) y la calidad de vida, así como la correlación de la EPOC con síntomas depresivos en sujetos antillanos. Métodos: Se realizó un estudio observacional transversal de pacientes ambulatorios con EPOC en cuidados terciarios. La severidad de la EPOC fue determinada por la etapa de la Iniciativa Global para la Enfermedad Pulmonar Obstructiva Crónica (GOLD, en inglés), el grupo GOLD, así como el índice de masa corporal, la obstrucción del flujo de aire, la disnea y la capacidad de ejercicio (índice BODE). La calidad de vida fue evaluada mediante el Cuestionario Respiratorio de Saint George (CRSG) y la prueba de evaluación de la EPOC (CAT, en inglés), en tanto que la depresión fue evaluada por la Escala de Depresión del Centro de Estudios Epidemiológicos (CES-D). Resultados: Un total de 105 pacientes (85.7% varones, 37.1% indotrinitenses, 42.9% afrotrinitenses, 64.8% nivel de educación primaria) fueron reclutados con una edad promedio de 66.9 años (desviación estándar: 9.60 años). El índice de masa corporal promedio fue de 25 kg/m2; 26.7% por debajo del peso normal. Los factores de riesgo identificados fueron: fumar ocasionalmente (27.6%), marihuana (20%), biomasa (81.9%), humo pasivo (70.5%), exposición ocupacional (80%). El CES-D del 25% de los pacientes fue ≥ 16. Las comorbilidades incluyeron diabetes (22%), hipertensión (29%), enfermedad por reflujo gastroesofágico (10%), y previo infarto del miocardio (15%). Un total de 59% de los pacientes reportaron un ingreso mensual familiar de menos de $800 USD. El nivel más bajo de educación se asoció con un peor (CRSG) (total e impacto), menor volumen espiratorio forzado en un segundo, Escala del Consejo de Investigaciones Médicas modificada (mMRC) de ≥ 2, y más alto índice de BODE. Un grupo más alto de GOLD se correlacionó con peores resultados de CRSG, CAT y CES-D. El CES-D más alto se asoció con una caminata de una distancia más corta en seis minutos, peores puntuaciones de CRSG, CAT y mMRC, un grupo más alto de GOLD, y mayores ingresos de EPOC por año. Los pacientes con CES-D de ≥ 16 caminaron distancias más cortas. El cuartil más alto de BODE estuvo asociado con las puntuaciones peores de CRSG, CAT y CES-D. Conclusión: El grupo GOLD más alto y el cuartil más alto de BODE se asociaron con peores puntuaciones de calidad de vida y puntuaciones de depresión más altas. Los pacientes en los grupos de GOLD más altos deben ser tamizados para detectar si padecen depresión. La educación sobre la EPOC debe estar dirigida a aquellos que tienen una situación socioeconómica inferior.

Effects of smoking cessation on pulmonary function and quality of life

Background: Cigarette smoking is a major public health problem and is the most important cause of chronic obstructive pulmonary disease (COPD). This study shows the importance of smoking cessation for improvement in respiratory function and quality of life and brings out the potential usage of pharmacological and behavioural therapy for the same.Methods: This prospective study was conducted on 50 male smokers at Kilpauk Medical College, Chennai. During the treatment only 43 patients were continued till the end of follow up. During the period, varenicline treatment was given for three months as per schedule, regular periodic counselling was given to these patients and followed up for a period of 1 year. Forced expiratory volume at one second (FEV1), COPD assessment test (CAT) scoring, 6 min walk test (6MWD), BODE index, was taken before starting therapy and on 3rd month and at the end of one year of follow-up. All the values obtained were analysed statistically.Results: The mean age of the 43 patients was 44.7±7.34, mean BMI was 22.27±4.24. The mean difference between pre and post treatment scores of CAT, 6MWD and BODE index were found to be statistically significant (p<0.0001).Conclusions: Combined behavioural counseling and pharmacotherapy with varenicline significantly improved the odds of achieving tobacco abstinence in the participants by the end of one year of treatment.

Effect of Fufei Gushen Decoction on BODE Index of Patients with Chronic Obstructive Pulmonary Disease at Stable Stage / 广州中医药大学学报

Objective To observe the effect of Fufei Gushen Decoction on the BODE index, an index for body mass index(BMI), airflow obstruction, dyspnea, and exercise capacity, in severe and extremely severe chronic obstructive pulmonary disease (COPD) patients with lung-kidney deficiency interweaved with phlegm and blood stasis at stable stage. Methods Eighty qualified COPD patients were randomly divided into treatment group and control group, 40 cases in each group. Both groups were given inhalation of Seretide (Salmeterol Xinafoate and Fluticasone Propionate Powder for inhalation) , and the treatment group was given oral use of Fufei Gushen Decoction additionally. The treatment for the two groups lasted for 3 months. Before and after treatment, BMI, the percentage of forced expiratory volume in one second of the predicted value (FEV1%) , dyspnea index of modified British Medical Research Council (MMRC), and exercise performance index of 6-min walking test (6MWT) in the two groups were observed. Results (1) After treatment, FEV1%, MMRC dyspnea index, 6MWT scores and BODE index overall scores of severe and extremely severe patients in the treatment group were much improved(P 0.05). MMRC dyspnea index, 6MWT scores and BODE index overall scores of severe and extremely severe patients inthe control group were much improved (P 0.05).(2) Except for BMI, the parameters of FEV1%, MMRC dyspnea index, 6MWT scores and BODE index overall scores of the treatment group were much improved as compared with those of the control group after treatment(P < 0.05). Conclusion Fufei Gushen Decoction combined with inhalation of Seretide exerts certain effects on decreasing the BODE index scores, relieving symptoms, and improving pulmonary function, exercise performance and the quality of life of COPD patients with lung-kidney deficiency interweaved with phlegm and blood stasis at stable stage.

Evaluation of BODE index as a predictor of Pulmonary Hypertension in COPD patients.

Background: The severity of COPD is usually assessed on the basis of a single parameter – forced expiratory volume in one second (FEV1). However, the patients with COPD have systemic manifestations that are not reflected by the FEV1. The present study was undertaken to determine the predictive value of BODE index (Body-mass index (B), the degree of airflow obstruction (O) ,dyspnea (D), and exercise capacity (E) for development of pulmonary hypertension and as a predictor of severity in COPD patients. The original BODE index is a simple multidimensional grading system which is superior to FEV1 alone for prediction of mortality and hospitalization rates among COPD patients. Methods: This study was done from January 2013 to December 2014.Total one hundred male patients who attended the chest medicine department, with the symptoms suggestive of COPD were included in this study and the study was done to evaluate the BODE index and correlated with echo-cardigraphic findings suggestive of pulmonary hypertension as a predictor of severity in patients with COPD. Result: Among patients with COPD, there were (21%) patients who had mild COPD with a BODE score between 0 – 2, Moderate COPD (BODE score of 3 – 5) were (23%), Severe COPD (BODE score more than or equal to 6) groups had (56%) patients. The study results showed that as the BODE index scores severity increases the incidence of pulmonary hypertension increases as identified by echocardiography RVSP (Right ventricular systolic pressure) findings. The average RVSP was 59.6 in severe COPD patients (BODE index more than 6) 47.2 in moderate severe COPD (BODE index 3-5), while it was less than 36 in mild groups. These values were found to be significant on comparison to other groups. Conclusion: BODE index may offer superior and alternative reliable method to predict severity in patients with COPD in terms of pulmonary hypertension and for following up after medications. Since the assessment of BODE index requires only a spirometer, which is relatively inexpensive and can easily be made available, this index could be of great practical value in a primary health care setup to identify individuals who are at need for further evaluation in a higher referral center. Thus, BODE index can be used for judicious referral of patients with COPD thereby preventing the wastage of the limited resources available.

Objective To investigate the Du moxibustion therapy in the treatment of chronic obstructive pulmonary disease (Chronic obstructive pulmonary disease,COPD)at stable phase.Methods 60 cases of lung COPD patients in stable stage who received treatment from January to December 2010 in Taihe Hospital of Traditional Chinese Medicine outpatient were randomly divided into two groups in,according to the case of tail number,with 30 patients in each.The control group was taken oral doxofylline tablets,0.2 g/time,2 time/d and ambroxol hydrochloride,30 mg/time,3 time/d.The treatment group was treated with Du moxibustion two times on the basis of the control group.One year follow-up and pulmonary function and BODE index assessment were performed in each group.Results ① the pulmonary function of the treatment group after the treatment (65.58±7.90) ％ was significantly improved than the same group before the treatment (53.20± 7.37) ％ (P＜0.05),and had significant difference compared with the control group after the treatment (57.53 ± 7.22)％ (P＜0.05).The recurrence rate was significantly different in the treatment group (1.79±0.32) and the control group (2.09±0.38) (P＜0.05).② BMI,MMRC,6MWD,BODE index,shortness of breath,wheezing,anorexia was significantly improved after the treatment in the treatment group [after treatment were (21.98 ± 1.32)kg/m2,(2.09±0.37)％,(350.68±88.70),(3.82±2.18) meters,(0.38±0.27),(0.32±0.25)％,(0.35±0.27) respectively; before treatment were (18.21±2.49)kg/m2,(2.50±0.43)％,(324.88±70.92),(4.66±1.40) meters,(1.49±0.62) ％,(1.42±0.56)％,(1.77±0.35),P＜0.01 respecitively].Compared with the control treatment after the treatment [(18.20 ± 1.79) kg/m2,(2.36 ± 0.64) ％,(320.03 ± 68.53),(4.43 ±1.62) meters,(1.22± 0.71),(1.28±0.67)％,(1.73±0.24) respectively] (P＞0.01),the difference was statistically significant(P＜0.01).Conclusion Du moxibustion therapy was effective in treating chronic obstructive pulmonary diseases in stable phase.

Does the BODE index reflect the level of physical activity in daily life in patients with COPD? / O índice BODE reflete o nível de atividade física na vida diária de pacientes com DPOC?

OBJECTIVES: To study the relationship between the level of physical activity in daily life and disease severity assessed by the BODE index in patients with chronic obstructive pulmonary disease (COPD). METHODS: Sixty-seven patients with COPD (36 men) with forced expiratory volume in the first second (FEV1) of 39 (27-47) percent predicted and age of 66 (61-72) years old were evaluated by spirometry, dyspnea levels (measured by the Medical Research Council scale, MRC) and by the 6-minute walking test (6MWT). The BODE index was calculated based on the body mass index (weight/height²), FEV1, MRC and 6MWT, and then the patients were divided in four quartiles according to their scores (Quartile I: 0 to 2 points, n=15; Quartile II: 3 to 4 points, n=20; Quartile III: 5 to 6 points, n=23; Quartile IV: 7 to 10 points, n=9). Two activity monitors (DynaPort® and SenseWear®) were used to evaluate the level of physical activity in daily life. The Kruskal-Wallis test (Dunns's post-hoc test), the Mann-Whitney test and the Spearman Correlation Coefficient were used for statistical analysis. RESULTS: There were modest correlation between the BODE index and the time spent walking per day, the total daily energy expenditure and the time spent in moderate and vigorous activities per day (-0.32 < r <- 0.47; p<0.01 for all variables). When comparing the pooled quartiles I+II with III+IV, there were significant difference between the time spent walking per day, the total daily energy expenditure and the time spent in moderate activities per day (p<0.05). CONCLUSION: The level of physical activity in daily life has a modest correlation with the classification of COPD severity assessed by the BODE index, reflecting only differences between patients with classified as mild-moderate and severe-very severe COPD.

OBJETIVOS: Estudar a relação entre nível de atividade física na vida diária (AFVD) e gravidade da Doença Pulmonar Obstrutiva Crônica (DPOC) avaliada pelo índice BODE. MÉTODOS: Sessenta e sete pacientes com DPOC (36 homens), com volume expiratório forçado no primeiro segundo (VEF1) 39(27-47) por centoprevisto, e 66(61-72)anos foram submetidos a avaliações de espirometria, grau de dispneia (Medical Research Council scale, MRC) e teste de caminhada de 6 minutos (TC6). O índice BODE foi calculado com base no índice de massa corpórea (peso/estatura²), VEF1, MRC e TC6, e os pacientes foram subdivididos em quatro quartis de acordo com sua pontuação no BODE (quartil I: 0 a 2 pontos, n=15; quartil II: 3 a 4 pontos, n=20; quartil III: 5 a 6 pontos, n=23; quartil IV: 7 a 10 pontos, n=9). O nível de AFVD foi avaliado por dois monitores de atividade física (DynaPort® e SenseWear®). Os testes de Kruskal-Wallis (pós-teste Dunns), Mann-Whitney e Coeficiente de Correlação de Spearman foram utilizados na análise estatística. RESULTADOS: Houve correlação modesta entre os escores do índice BODE e o tempo gasto andando/dia, gasto energético total e tempo gasto/dia em atividades moderadas e vigorosas (-0,32< r <-0,47; p<0.01 para todos). Quando comparados os quartis agrupados I+II com III+IV, houve diferença significante entre o tempo gasto andando/dia, gasto energético total e tempo gasto em atividades moderadas (p<0,05). CONCLUSÃO: O nível de AFVD apresenta correlação modesta com a classificação da gravidade da DPOC dada pelo índice BODE, refletindo apenas diferenças entre pacientes com doença leve-moderada e grave-muito grave.

Three-year follow-up study of respiratory and systemic manifestations of chronic obstructive pulmonary disease

Few studies show patient outcomes over time in chronic obstructive pulmonary disease (COPD). In the present study, we monitored forced expiratory volume in the first second (FEV1) and other manifestations of the disease over 3 years in 133 COPD patients (69 percent males, age = 65 ± 9 years, FEV1 = 59 ± 25 percent) evaluated at baseline. During follow-up, 15 patients (11 percent) died and 23 (17 percent) dropped out. Measurements for 95 (72 percent) COPD patients alive after 3 years were analyzed. FEV1, body mass index (BMI), 6-min walking distance (6MWD), Medical Research Council scale (MRC), Saint George’s Respiratory Questionnaire (SGRQ), Charlson Comorbidity index, and BODE index were obtained at baseline and after 3 years. At baseline, 17 patients (18 percent) presented mild, 39 percent moderate, 19 percent severe, and 24 percent very severe COPD. Predicted FEV1 percent and BMI did not change over the period (P > 0.05). FEV1 in liters [1.25 (0.96-1.72) vs 1.26 (0.88-1.60) L; P < 0.001], 6MWD (438 ± 86 vs 412 ± 100 m; P < 0.001), MRC [1 (1-2) vs 2 (1-3); P = 0.002], Charlson index [3 (3-4) vs4 (3-5); P = 0.009], BODE index (2.2 ± 1.8 vs 2.6 ± 2.3; P = 0.008), and total SGRQ (42 ± 19 vs 44 ± 19 percent; P = 0.041) worsened after 3 years compared to baseline measurements. These data show that COPD patients deteriorated during the 3-year follow-up despite the fact that they had only minor modifications in airway obstruction and body composition. They support the need for comprehensive patient assessment to better identify disease progression.

Application value of BODE index in patients with chronic obstructive pulmonary disease in rural China / 中国综合临床

Objective To evaluate the application value of BODE and the relationship between BODE index and life quality in patients with chronic obstructive pulmonary disease (COPD) in rural China. Methods A total of 26 rural patients with stable COPD were enrolled. BODE index and it's four components including body mass index ( BMI ), airflow obstruction ( FEV1 % ), dyspnea ( MMRC ) and exercise capacity ( 6MWD ) were calculated. St. Georgeps Respiratory Questionnaire (SGRQ) were used to evaluate health-related quality of life of these patients. Results The BODE index was significantly correlated with the SGRQ total score , symptom ,activity and impact score ( r = 0. 674,0. 430,0. 460,0. 495 respectively, Ps ＜ 0. 05 ). GOLD grade was only significantly correlated with the SGRQ total score and active score( r =0. 447,0. 418 ,Ps ＜0. 05 ). Stepwise liner multiple regression analysis showed that activity score of SGRRQ was an influence factor of BODE index. 6MWD of BODE index( t = - 2. 397, P = 0. 025 ) and MMRC ( t = 2. 257, P = 0. 034 ) were independently correlated with activity scores of SGRQ . Conclusion BODE index and life quality had significant relationship. 6MWD and MMRC of BODE index were the most powerful influence factors of life quality in rural COPD patients.

Neurophysiological aspects and their relationship to clinical and functional impairment in patients with chronic obstructive pulmonary disease

OBJECTIVE: The purpose was to assess functional (balance L-L and A-P displacement, sit-to-stand test (SST) and Tinetti scale - balance and gait) and neurophysiological aspects (patellar and Achilles reflex and strength) relating these responses to the BODE Index. INTRODUCTION: The neurophysiological alterations found in patients with chronic obstructive pulmonary disease (COPD) are associated with the severity of the disease. There is also involvement of peripheral muscle which, in combination with neurophysiological impairment, may further compromise the functional activity of these patients. METHODS: A cross-sectional study design was used. Twenty-two patients with moderate to very severe COPD (>60 years) and 16 age-matched healthy volunteers served as the control group (CG). The subjects performed spirometry and several measures of static and dynamic balance, monosynaptic reflexes, peripheral muscle strength, SST and the 6-minute walk test. RESULTS: The individuals with COPD had a reduced reflex response, 36.77±3.23 (p<0.05) and 43.54±6.60 (p<0.05), achieved a lower number repetitions on the SST 19.27±3.88 (p<0.05), exhibited lesser peripheral muscle strength on the femoral quadriceps muscle, 24.98±6.88 (p<0.05) and exhibited deficits in functional balance and gait on the Tinetti scale, 26.86±1.69 (p<0.05), compared with the CG. The BODE Index demonstrated correlations with balance assessment (determined by the Tinetti scale), r = 0.59 (p<0.05) and the sit-to-stand test, r = 0.78 (p<0.05). CONCLUSIONS: The individuals with COPD had functional and neurophysiological alterations in comparison with the control group. The BODE Index was correlated with the Tinetti scale and the SST. Both are functional tests, easy to administer, low cost and feasible, especially the SST. These results suggest a worse prognosis; however, more studies are needed to identify the causes of these changes and the repercussions that could result in their activities ...

Short-term effect of video-thoracoscope in the treatment of chronic obstructive pulmonary diseases accompanied with pneumothorax / 中国综合临床

Objective To study the short-term(≤1 year) effect of video-thoracoscope in the treatment of chronic obstructive pulmonary diseases (COPD) accompanied with pneumothorax.Methods 52 COPD cases with pneumothorax from June 2005 to June 2007 were divided into thoracoscope group(n=28) and open heart group(n=24).The patients were followed up at 1,6 and 12 month after surgery,for determination of BODE index,including body mass index,air block,difficulty in respiratory and motor ability.Results No operative death and servere complicatins occurred.Pneumothorax did not relapse.One month after surgery,air block was[(58.62±15.73)% vs (50.12±11.38)%],difficulty in respiratory was[(1.04±0.37)s vs( 1.72±0.45)s] and motor ability was [(387.32±52.07)m vs (318.35±61.52)m] in thoracoscope group and open heart group (P<0.05).At the six month after surgery,body mass index was[(27.19±2.18)kg/m2 vs (20.90±2.35)kg/m2] in thoracoscope group and open heart group(P<0.05);At the 12 month after operation,there was no significant difierence in BODE index between the two groups(P>0.05).Conclusions Video-thoracoscope in treating COPD with pneumothorax can remarkably improve the quality of life early after surgery.

Exacerbaciones en pacientes ex-fumadores con enfermedad pulmonar obstructiva crónica: efectos clínicos y funcionales a corto plazo / Short term effects of acute exacerbations in COPD patients

Acute exacerbations of COPD (AECOPD) are associated with decline of FEV1 and health related quality of life. Our aim was to evaluate the short-term effects of AECOPD on several functional and clinical indices in a cohort of 60 ex-smokers patients with COPD. During a 6-month follow up, 40 patients experienced one exacerbation (Group 1), mainly moderate, evaluated 30 days after by measuring BMI, dyspnea, FVC, FEV1, inspiratory capacity (IC), Sp02, six-min walking distance (6MWD), BODE index and quality of life (SGRQ). Values were compared with those measured at recruitment in stable conditions and with those obtained in the 20 patients without AECOPD during a similar period (Group 2). Baseline values were similar in both groups. Group 1 showed a significant worsening in FVC, FEV1, Sp02, BMI, 6MWD, and BODE index. Improvement in SGRQ and BODE was found in group 2. Significant differences in changes between groups were found for all variables, except IC and Sp02. The most noteworthy differences were found for BODE index (p = 0.001) and SGRQ (p = 0.004). Results demonstrate that moderate AECOPD produces significant short term functional and clinical impairment in ex-smokers COPD.

Las exacerbaciones de la EPOC deterioran el FEV1y la calidad de vida. Nuestro objetivo fue evaluar el efecto a corto plazo de las exacerbaciones sobre otros índices funcionales y clínicos. Sesenta pacientes ex fumadores con EPOC fueron seguidos durante 6 meses. Cuarenta presentaron una exacerbación (Grupo 1), generalmente moderada, estudiada 30 días después. los 20 pacientes no exacerbados constituyeron el grupo control (Grupo 2). Se midió IMC, disnea, CVF, FEV1h capacidad inspiratoria (CI), SpO2, caminata en 6 min (C6M), índice BODE y calidad de vida (SGRQ). En condiciones basales no hubo diferencias entre grupos. El grupo 1 empeoró CVF, VEF1, SpO2, IMC, C6M e índice BODE, sin cambios de CI ni SGRQ. El grupo 2 no presentó deterioro, mejorando SGRQ y BODE. Al comparar ambos grupos, hubo diferencias significativas en los cambios de todas las variables, excepto Cly SpO2, siendo estas diferencias más notorias en el índice BODE (p = 0,001) y SGRQ (p = 0,004). En suma, las exacerbaciones de la EPOC producen deterioro clínico y funcional significativo en el corto plazo.

Role of High-resolution Computed Tomography in Evaluation for Patients with Chronic Obstructive Pulmonary Diseases / 中国康复理论与实践

@#Objective To investigate the evaluation of high-resolution computed tomography (HRCT) in patients with chronic obstructive pulmonary diseases (COPD), and the relationship with the pulmonary function test and BODE index.Methods 32 COPD patients and 22 normal controls were examined by pulmonary function test (PFT) and HRCT. The data of two groups were compared.Results The volume and pixel index (PI) in forced expiration were higher in the COPD group than those in the control group ( P<0.01), but there was no significant difference in Vin between two groups ( P>0.05). In the COPD group, Vex and Vin were negatively correlated with FEV1/FVC ( P<0.05) respectively. There were no correlation between Vin, Vex and FEV1% pre in the COPD patients ( P>0.05) respectively. Vin and Vex were not correlated with BODE index (all P>0.05) respectively. The ratio of Vex/Vin was positively correlated with BODE index ( P<0.05), and not correlated with FEV1/FVC ( P>0.05). PI910ex was positively correlated with BODE index ( P<0.01), and negatively correlated with FEV1%pre, FEV1/FVC (all P<0.05) respectively.Conclusion The pulmonary function of COPD patients can be evaluated by HRCT, especially by PI910ex.
