RESUMO

In March 2020, a 74-year-old man affected by end-stage renal disease and on peritoneal dialysis was referred to an emergency room in Modena, Northern Italy, due to fever and respiratory symptoms. After ruling out COVID-19 infection, a diagnosis of chronic obstructive pulmonary disease exacerbation was confirmed and he was thus transferred to the nephrology division. Physical examination and blood tests revealed a positive fluid balance and insufficient correction of the uraemic syndrome, although peritoneal dialysis prescription was maximised. After discussion with the patient and his family, the staff decided to start hybrid dialysis, consisting of once-weekly in-hospital haemodialysis and home peritoneal dialysis for the remaining days. He was discharged at the end of the antibiotic course, after an internal jugular vein central venous catheter placement and the first haemodialysis session. This strategy allowed improvement of depuration parameters and avoidance of frequent access to the hospital, which is crucial in limiting exposure to SARS-CoV-2 in an endemic setting.

RESUMO

The Veneto region is one of the most affected Italian regions by COVID-19. Chronic lung diseases, such as chronic obstructive pulmonary disease (COPD), may constitute a risk factor in COVID-19. Moreover, respiratory viruses were generally associated with severe pulmonary impairment in cystic fibrosis (CF). We would have therefore expected numerous cases of severe COVID-19 among the CF population. Surprisingly, we found that CF patients were significantly protected against infection by SARS-CoV-2. We discussed this aspect formulating some reasonable theories.

RESUMO

OBJECTIVE: The aim: To evaluate the effect of overweight on the quality of life of chronic obstructive pulmonary disease (COPD) patients GOLD III. PATIENTS AND METHODS: Materials and methods: 65 patients with chronic obstructive pulmonary disease (COPD GOLD III) were examined in different phases of pathological process. The pulmonary function (PF) test was performed by means of "SPIROKOM" device (Ukraine). The degree of overweight was determined by calculating the body mass index (BMI) using the formula І = m/h² (m - body mass in kilograms, h - height, square of the height in meters (kg/m²). Patients' quality of life was evaluated with the help of standardized St.George's Respiratory Questionnaire (SGRQ). RESULTS: Results: The study revealed changes in the PF indices and the decrease in quality of life in overweight patients, especially in case of destabilization of the pathological process. CONCLUSION: Conclusions: The obtained results show that overweight is the underlying condition for more severe course of the pathology and requires further study of its impact on the health and quality of life of patients in order to improve the effectiveness of treatment.

RESUMO

INTRODUCTION: The COVID pandemic has had a high psychological impact on healthy populations. Increased levels of perceived stress, depression, and insomnia are expected, especially in people with pre-existing medical conditions, such as asthma and chronic obstructive pulmonary disease (COPD), who seem to be particularly vulnerable. However, the difference in psychological distress frequency between asthma and COPD patients is unknown. OBJECTIVE: To compare the prevalence of depression, perceived stress related to COVID, post-traumatic stress, and insomnia in asthma and COPD patients at a pulmonology clinic in Santa Marta, Colombia. METHODS: A cross-sectional study was designed. The patients were contacted by telephone. An electronic link was sent to those who accepted. The questionnaire asked for perceived stress related to COVID-19, post-traumatic stress symptoms, depressive symptoms, and insomnia risk. RESULTS: 148 asthma patients and 144 COPD patients participated in, between 18 and 96 years. The prevalence of high COVID-19 perceived stress was 10.6% (n = 31); post-traumatic stress risk, 11.3% (n = 33); depression risk, 31.5% (n = 92); and insomnia risk, 57.7% (n = 169). No significant differences were found between asthma and COPD in indicators of psychological distress. CONCLUSIONS: Asthma and COPD patients present similar frequencies of depression risk, COVID-19 perceived stress, post-traumatic stress risk, and insomnia risk during the Colombian lockdown. It is essential to evaluate and manage psychological distress among asthma and COPD patients. It can reduce the risk of exacerbation and improve the quality of life.

RESUMO

BACKGROUND: Cardiovascular diseases, cancer, type-2 diabetes and chronic obstructive pulmonary disease (COPD) were initially noted as the most common diseases among individuals who were hospitalised for COVID-19. However, the evidence base is weak. The objective of this study is to describe how selected diseases were distributed among adults with confirmed COVID-19 (COVID-19 positive tests) and among those hospitalised for COVID-19 compared to the general population. MATERIAL AND METHOD: We used data from the Norwegian Patient Registry, the Norwegian Registry for Primary Health Care and the Norwegian Surveillance System for Communicable Diseases for adults from the age of 20 and older for the period 1 March 2020-13 May 2020. RESULTS: Of all those who tested positive for COVID-19, 7 632 (94 %) were aged 20 years or older, and 1 025 (13.4 %) of these had been hospitalised. Among those hospitalised with COVID-19, there was a higher proportion of individuals with cardiovascular diseases (18.3 % versus 15.6 %), cancer (6.9 % versus 5.4 %), type-2 diabetes (8.6 % versus 5.2 %) and COPD (3.8 % versus 2.7 %) than in the general population as a whole after adjusting for age. The proportion of hospitalised patients with asthma, other chronic respiratory disease, cardiovascular disease, ongoing cancer treatment, complications related to hypertension, obesity and overweight, neurological disorders and cardiac and renal failure was also higher than in the general population. There were few differences between persons who had tested positive for COVID-19 and the general population in terms of underlying conditions. INTERPRETATION: Among those hospitalised for COVID-19, there was a higher proportion of patients with underlying illnesses than in the general population. This may indicate that these patients tend to have a more severe course of disease or that they are more likely to be hospitalised compared to healthy individuals. The results must be interpreted with caution, since the sample of COVID-19 individuals is non-random.

RESUMO

INTRODUCTION: chronic obstructive pulmonary disease (COPD) is 1 of the leading causes of morbidity and mortality worldwide; its economic and social burdens are substantial and increasing. Recent years, an increasing number of study has shown the promising advantage of Erchen decoction (ECD) combined with sanziyangqin decoction (SZYQD) in treating COPD. However, due to the lack of evidence, there is no specific method or suggestion, so it is necessary to provide a protocol for a systematic review on ECD combined with SZYQD for COPD and provide effective evidence for further clinical use. METHODS AND ANALYSIS: We will conduct a Computerized literature searches in the following databases: PubMed, MEDLINE, EMBASE, Cochrane Library, China national information network, China biomedical literature database (CBM), Chinese Scientific Journals Database and wanfang database, from their inception to June 2020, without restrictions of language. Study selection, data collection, and evaluation of the quality of evidence will be performed by 2 researchers independently, risk of bias of the meta-analysis will be evaluated based on the Cochrane Handbook for Systematic Reviews of Interventions. All data analysis will be conducted by data statistics software Review Manager V.5.3. and Stata V.12.0. RESULTS: This study will systematically evaluate the effectiveness and safety of ECD combined with SZYQD for COPD. The results will be published in a peer-reviewed journal. CONCLUSION: This study will provide evidence from the current published RCTs of whether ERD combined with SZYQD is an effective and safe intervention for COPD. ETHICS AND DISSEMINATION: This study is a systematic review, the outcomes are based on the published evidence. In this study, no individual data from participants will be involved, so ethics approval is not required. OPEN SCIENCE FRAMEWORK(OSF)REGISTRATION NUMBER: August 19, 2020; osf.io/zxm24.

RESUMO

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) has spread to almost 100 countries, infected over 31 M patients and resulted in 961 K deaths worldwide as of 21st September 2020. The major clinical feature of severe COVID-19 requiring ventilation is acute respiratory distress syndrome (ARDS) with multi-functional failure as a result of a cytokine storm with increased serum levels of cytokines. The pathogenesis of the respiratory failure in COVID-19 is yet unknown, but diffuse alveolar damage with interstitial thickening leading to compromised gas exchange is a plausible mechanism. Hypoxia is seen in the COVID-19 patients, however, patients present with a distinct phenotype. Intracellular levels of nitric oxide (NO) play an important role in the vasodilation of small vessels. To elucidate the intracellular levels of NO inside of RBCs in COVID-19 patients compared with that of healthy control subjects. METHODS: We recruited 14 COVID-19 infected cases who had pulmonary involvement of their disease, 4 non-COVID-19 healthy controls (without pulmonary involvement and were not hypoxic) and 2 hypoxic non-COVID-19 patients subjects who presented at the Masih Daneshvari Hospital of Tehran, Iran between March-May 2020. Whole blood samples were harvested from patients and intracellular NO levels in 1 × 106 red blood cells (RBC) was measured by DAF staining using flow cytometry (FACS Calibour, BD, CA, USA). RESULTS: The Mean florescent of intensity for NO was significantly enhanced in COVID-19 patients compared with healthy control subjects (P ≤ 0.05). As a further control for whether hypoxia induced this higher intracellular NO, we evaluated the levels of NO inside RBC of hypoxic patients. No significant differences in NO levels were seen between the hypoxic and non-hypoxic control group. CONCLUSIONS: This pilot study demonstrates increased levels of intracellular NO in RBCs from COVID-19 patients. Future multi-centre studies should examine whether this is seen in a larger number of COVID-19 patients and whether NO therapy may be of use in these severe COVID-19 patients.

RESUMO

Chronic obstructive pulmonary disease (COPD) is a lung disease affected by both genetic and environmental factors. Therefore, the role of epigenetics in the pathogenesis of COPD has attracted much attention. As one of the three epigenetic mechanisms, DNA methylation has been extensively studied in COPD. The present review aims at overviewing the effect of DNA methylation on etiology, pathogenesis, pathophysiological changes, and complications of COPD. The clarification of aberrant methylation of target genes, which play important roles in the initiation and progression of COPD, will provide new disease-specific biomarker and targets for early diagnosis and therapy.

RESUMO

Chronic obstructive pulmonary disease (COPD) is characterized by irreversible airflow obstruction and chronic airway inflammation, caused by a combination of environmental and genetic factors. It is the third leading cause of death worldwide. In recent years, researchers have applied the genome-wide association study (GWAS) and identified a large number of genetic variants associated with lung functions and potential drug targets for treating COPD. In this review, we summarize the results of GWAS studies and perform a review of the literature since 2007 to highlight the progress of GWAS on COPD. We discuss the challenges, the underlying mechanisms, and the possible drug targets, thereby providing insights on the pathogenesis and potential treatment strategies for COPD.
