AbstractChronic obstructive lung disease (COPD) is a severe progressive disease associated with high morbidity and mortality. Early diagnosis and correct treatment improve the symptoms, quality of life and survival in COPD. Exacerbations of the disease are acute events that cause worsening of COPD symptoms (dyspnea, cough and/or sputum) and may require modification of stable COPD therapy. COPD exacerbations add inflammation, damage the quality of life, deteriorate the lung function, increase mortality and associate high socio-economic costs. Accurate early prediction of exacerbation and mortality risk facilitates patient selection upon risk, in order to provide appropriately targeted early treatment. The risk of having frequent exacerbations is clearly demonstrated by recognized studies in patients with specific criteria: previous exacerbation in the last year, decrease in FEV1s, increase in the score of St. George Questionnaire (life quality decline), high levels of several inflammatory biomarkers, such as neutrophils, C-reactive protein (CRP), fibrinogen, pro-calcitonin, eosinophils, IL-6, IL-8, chemokine ligand 18 (CCL-18/PARC), surfactant protein D (SP-D). Simultaneously elevated levels of CRP, fibrinogen and leukocyte count in COPD patients were associated with an increased risk for exacerbations. At the same time, elevated levels of the three biomarkers are associated with an increased risk of major comorbidities in COPD. Biomarker detection may be an additional tool for assessment and management of COPD comorbidities. Detection of pathologic levels of inflammatory biomarkers improves the ability to predict the risk mortality in COPD alongside with BODE index (BMI, obstruction in lung function, dyspnea scale, 6-minute walk test) and may provide a targeted treatment.

Purpose:Tiotropium (SPIRIVA®) is used in the treatment of moderate to severe chronic obstructive pulmonary disease (COPD) in patients with persistent dyspnea despite using a short acting bronchodilator (SABD).This paper explores the role of tiotropium in the treatment of mild COPD. Methods:The Cochrane Library, EMBASE, Pubmed, and Clinicaltrials.gov were searched on February 2018.We included randomized controlled trials (RCTs) that evaluated tiotropium in patients with mild COPD.Three authors assessed studies for eligibility. Outcomes included symptoms, quality of life, exercise duration, lung function, COPD exacerbations and hospitalizations, and serious adverse events. Results: Three RCTs were selected as the best available evidence. Based on the results of the main trial, quality of life and symptoms were improved with tiotropium as compared to placebo with a difference between groups at 24 months to be 1.2 (95% CI: 0.5 to 1.9; p=0.0011) using the COPD Assessment test (CAT) score. Frequency of acute exacerbations of COPD (AECOPD) requiring hospitalization was reduced by 10.3% (28.9% with tiotropium vs 39.2% with placebo) in patients receiving tiotropium. One RCT reported no statistically significant difference in exercise duration (27 ± 27 secs) in the tiotropium group vs 50 ± 21 secs in the placebo group; (p=0.4153). Oropharyngeal discomfort was more common with tiotropium (number needed to harm of 12) compared to placebo. Conclusions: Evidence suggests that tiotropium may reduce COPD exacerbations and hospitalizations and improve quality of life in patients with mild COPD.There is an increased risk of oropharyngeal discomfort with tiotropium.

Regarding the widely distribution of respiratory exposure hazards in occupational settings, workers have an increased risk for chronic lung diseases. For assessing the quality of life and lung function in workers exposed to chemicals and dust, St George�s Respiratory Questionnaire (SGRQ) and spirometry were performed among 40 patients, admitted in Occupational Clinic Department of Colentina Hospital, Bucharest, Romania, during February, 2017. SGRQ showed different predictors for patients according to their occupational exposure and total symptoms score correlated better with decreased spirometric parameters in defining lung function deterioration. Quality of life is earlier affected than lung function deterioration and emphasises the need of more sensitive methods for an earlier identification and better evaluation of respiratory hazards in different workplaces.

Abstract BackgroundA growing body of evidence suggests a role for oral bacteria in lung infections. This systematic review aimed to analyse the association between poor periodontal health and the frequency of chronic obstructive pulmonary disease (COPD) exacerbations. MethodsPubMed, Embase, Web of Science, CINAHL and Medline were searched for studies published until May 2020, with no language restriction. Studies reporting periodontal condition, or periodontal treatment outcomes, with data on the frequency of exacerbations of COPD, were identified. The primary outcome was the frequency of exacerbations and secondary outcomes included quality of life and hospitalisation. Studies were assessed for eligibility and quality by two assessors independently.Results Searches identified 532 records and 8 met the inclusion criteria. The data from intervention studies showed reduction in the frequency of exacerbations following periodontal treatment. Data from observational studies suggest association of worse plaque scores with exacerbation but not pocket depth or clinical attachment loss. Better periodontal health was also associated with reduced frequency of COPD exacerbations, hospitalisations and improved quality of life in COPD patients. Due to the high heterogeneity no meta-analysis was performed. The quality of some of the included studies was low and there was evidence of high risk of bias.ConclusionThe data supports possible association between poor periodontal health, the frequency of exacerbations and quality of life in COPD patients. The evidence is limited by high risk of bias suggesting need for well-designed and adequately powered randomised control trials.The PROSPERO registration number CRD42020180328

Összefoglaló. Bevezetés: Krónikus obstruktív tüdőbetegségben (COPD) az obesitas mellett a csökkent fizikai aktivitás nagymértékben fokozza a metabolikus szindróma kialakulásának valószínűségét. Célkitűzés: Kutatásunk célja volt felmérni a metabolikus szindróma prevalenciáját COPD-ben, valamint azt, hogy milyen mértékben függ össze az életkorral, a nemmel, a társbetegségekkel, a tüdőfunkció károsodásának mértékével, a tápláltsági állapottal, a fizikai terhelhetőséggel és az életminőséggel. Módszer: Keresztmetszeti vizsgálatot végeztünk az Országos Korányi Pulmonológiai Intézet Légzésrehabilitációs Osztályán fekvő betegek körében 2019. július 1. és december 31. között. A véletlenszerűen kiválasztott 300, 40 év feletti betegnek ismertük az antropometriai, légzésfunkciós vizsgálati eredményét és laboratóriumi paramétereit. Adatokat gyűjtöttünk a dohányzási szokásokról, az előző évi exacerbatiók számáról és a kortikoszteroidok használatáról is. Az életminőség mérésére a betegségspecifikus Szent György-féle Légzési Kérdőív magyar nyelvre validált változatát használtuk. A metabolikus szindrómát a Nemzetközi Diabetes Szövetség kritériumai alapján határoztuk meg. Eredmények: A metabolikus szindróma a betegek 72%-ánál fordult elő, férfi: 65,9% nő: 77,2% (p = 0,031). A metabolikus szindrómás betegek esetében rövidebb 6 perces sétatávolságot mértünk ([m] 250 [150–330] vs. 295 [162–360]; p = 0,384), és szignifikánsan több volt az előző évi exacerbatiók száma (3 [0–6] vs. 1 [1–2]; p<0,001) a nem metabolikus szindrómás betegekhez képest. A BMI-re történő stratifikáció után a metabolikus szindróma jelenléte nagyobb volt BMI≥25 kg/m2 esetén. A hasi elhízás, a magas vérnyomás, a hyperlipidaemia és a hyperglykaemia szignifikánsan gyakoribb volt BMI≥25 kg/m2 esetén (p<0,001). Következtetés: Eredményeink azt sugallják, hogy a metabolikus szindrómás betegekben megnő az együttes morbiditási index, különösen azok körében, akik túlsúlyosak vagy elhízottak. Ezért a COPD-s betegekben nagyon fontos időben felismerni és megfelelően kezelni a metabolikus szindrómát. Orv Hetil. 2021; 162(5): 185–191. Summary. Introduction: Both obesity and the lack of physical activity among chronic obstructive pulmonary disease (COPD) patients increase the risk of developing metabolic syndrome. Objective: The goal of our study was to assess the prevalence of metabolic syndrome among COPD patients and to examine its correlation with age, gender, comorbidities, lung function values, nutritional status, exercise capacity, and quality of life. Method: A cross-sectional study was performed at the Department of Pulmonary Rehabilitation of the Hungarian National Korányi Institute for Pulmonology between July 1st and December 31st, 2019. A total of 300 patients aged over 40 were selected at random. Anthropometric data were collected along with lung function values, laboratory parameters, smoking status, the number of exacerbations in the previous year, and the use of corticosteroids. Quality of life was measured by the validated Hungarian, COPD-specific Saint George Respiratory Questionnaire. Metabolic syndrome was defined according to the International Diabetes Federation criteria. Results: Metabolic syndrome affected 72% of COPD patients (male: 65.9%, female 77.2%; p = 0.031). In patients with metabolic syndrome, shorter 6-minute walking distance was measured ([m] 250 [150–330] vs. 295 [162–360]; p = 0.384) and the number of exacerbations in the previous year was significantly higher (3 [0–6] vs. 1 [1–2]; p<0.001) compared to patients with no metabolic syndrome. After stratification for BMI, metabolic syndrome was more frequent in the case of BMI≥25 kg/m2. Central adiposity, hypertension, hyperlipidemia, and hyperglycemia were also significantly more frequent among patients with BMI≥25 kg/m2 (p<0.001). Conclusion: Our results suggest that the co-morbidity index increases in patients with metabolic syndrome, especially in overweight or obese patients. Therefore, early detection and appropriate treatment of metabolic syndrome in patients with COPD is very important. Orv Hetil. 2021; 162(5): 185–191.
