Abstract Objective Chronic obstructive pulmonary disease (COPD) is a complicated multi-factor, multi-gene disease. Here, we aimed to assess the association of genetic polymorphisms in LINC01414/ LINC00824 and interactions with COPD susceptibility. Methods Three single nucleotide polymorphisms (SNPs) in LINC01414/LINC00824 was genotyped by Agena MassARRAY platform among 315 COPD patients and 314 controls. Logistic analysis adjusted by age and gender were applied to estimate the genetic contribution of selected SNPs to COPD susceptibility. Results LINC01414 rs699467 (OR = 0.73, 95% CI 0.56–0.94, p = 0.015) and LINC00824 rs7815944 (OR = 0.56, 95% CI 0.31–0.99, p = 0.046) might be protective factors for COPD occurrence, while LINC01414 rs298207 (OR = 2.88, 95% CI 1.31–6.31, p = 0.008) risk-allele was related to the increased risk of COPD in the whole population. Rs7815944 was associated with the reduced risk of COPD in the subjects aged > 70 years (OR = 0.29, p = 0.005). Rs6994670 (OR = 0.57, p = 0.007) contribute to a reduced COPD risk, while rs298207 (OR = 7.94, p = 0.009) was related to a higher susceptibility to COPD at age ≤ 70 years. Rs298207 (OR = 2.54, p = 0.043) and rs7815944 (OR = 0.43, p = 0.028) variants was associated COPD risk among males. Rs7815944 (OR = 0.16, p = 0.031) was related to the reduced susceptibility of COPD in former smokers. Moreover, the association between rs298207 genotype and COPD patients with dyspnea was found (OR = 0.50, p = 0.016), and rs7815944 was related to COPD patients with wheezing (OR = 0.22, p = 0.008). Conclusion Our finding provided further insights into LINC01414/LINC00824 polymorphisms at risk of COPD occurrence and accumulated evidence for the genetic susceptibility of COPD.

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.

INTRODUÇÃO: DPOC está associada a um processo inflamatório sistêmico que pode causar sarcopenia, redução da função e massa muscular, embora sua frequência e intensidade não seja completamente conhecida em portadores dessa enfermidade. OBJETIVO: descrever a prevalência e métodos de identificação da sarcopenia na DPOC através de uma revisão sistemática. MATERIAIS E MÉTODOS: Revisão sistemática utilizando a metodologia PICO e palavras-chave (Chronic Obstructive Pulmonary Disease, Sarcopenia). Foram incluídos estudos publicados que estimaram a prevalência de sarcopenia na DPOC. Excluídos aqueles cujo método não detalhou o diagnóstico da sarcopenia. RESULTADOS: A pesquisa resultou inicialmente em 897 artigos. Desses, 877 foram excluídos, sendo 20 selecionados (15 transversais, cinco longitudinais, um caso/controle). As amostras variaram de 57 a 2.582 participantes, a maioria (70%) conduzida em ambulatório. Um estudo foi de base populacional. A idade média foi de 66 anos. A prevalência de sarcopenia na DPOC variou (4,4% a 86,5%). Os métodos diagnósticos utilizados para determinar massa muscular foram o Dual X-ray Absorptiometry, a bioimpedância e as equações de referência. A força muscular foi estimada utilizando-se a preensão manual em dinamômetros portáteis ou a flexão/extensão do joelho através do dinamômetro isocinético. A capacidade funcional foi avaliada pelo teste de caminhada dos seis minutos ou através do teste de velocidade da marcha. CONCLUSÃO: A prevalência de sarcopenia na DPOC encontrada nos estudos (4,4 a 86,5%) é muito variável. Influenciada não somente pela característica do paciente, mas também pelo local, delineamento e método diagnóstico utilizado. Uma padronização de métodos parece ser necessária para se uniformizar condutas na literatura.

Aim. To identify methods for diagnosing early signs of heart failure in patients with chronic obstructive pulmonary disease. Methods. We examined 54 patients with chronic obstructive pulmonary disease without exacerbation. Patients were divided into two groups: group 1 - 26 patients with chronic obstructive pulmonary disease in combination with chronic heart failure; group 2 - 28 patients with chronic obstructive pulmonary disease without chronic heart failure. The groups were comparable by age and severity of chronic obstructive pulmonary disease. Electrocardiography, echocardiography were performed with additional determination of the right heart chamber parameters, spirometry, X-ray, pulse oximetry. The level of highly sensitive C-reactive protein, blood acid-base composition and brain natriuretic peptide was evaluated. Results. Patients with comorbidity have decreased exercise tolerance according to the 6-minute walk test and mMRS scale, higher body mass index and dyspnea intensity, larger linear dimensions of the heart chambers and their volume parameters. Heart failure with preserved ejection fraction was observed in 21 (80%) of patients in group 1, therefore, the signs of heart failure can be explained by diastolic dysfunction of the right and left ventricles. Among patients with chronic obstructive pulmonary disease and chronic heart failure in our study, extended linear dimensions and structural changes in the ventricles, indicating pre- and postcapillary hypertension, were significantly more common. Conclusion. The use of tissue Doppler study allows more accurately determining the diastolic function of the right and left ventricles; the brain natriuretic peptide study is a sensitive marker of early forms of diastolic chronic heart failure.

INTRODUCTION: The individual with chronic obstructive pulmonary disease (COPD) can experience a significant reduction of body composition, peripheral muscle dysfunction, resulting in a negative influence on functional capacity. OBJECTIVES: To analyze the influence of body composition assessed by dual-energy x-ray absorptiometry on functional capacity of patients with chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS: Eleven male patients with COPD (COPDG), seven presenting moderate obstruction and four severe, and 11 sedentary male subjects (CG) were evaluated by dual-energy x-ray absorptiometry to assess their body composition. All subjects also performed the 6-minute walk test (6MWT) and Step Test (6MST) to assess their functional capacity. RESULTS: No significant differences were found between groups for anthropometric data such as age, weight, height and body mass index (BMI). However, the COPDG presented Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), FEV1/FVC ratio, Maximal Voluntary Ventilation (MVV), Walked Distance (WD) and Number of Steps (NS) significantly lower than the CG (p < 0.05, Student's t-test). The Body Bone Mass (BBM), BBM%, Lean Mass (LM), LM%, and Right Lower Limb (RLL) and Left Lower Limb (LLL) were significantly lower in the COPDG when compared with the CG, presenting statistically significant positive correlations with 6MWT's WD and 6MST's NS (p < 0.05, Pearson's test). CONCLUSION: We conclude that body composition is an important prognostic factor for patients with COPD, which reinforces the importance of assessing body composition by dual-energy absorptiometry since it has demonstrated with satisfactory accuracy in clinical practice. Moreover, it is a useful parameter for evaluation and reassessment in pulmonary rehabilitation programs.
