Monocyte related haematological indices in acute exacerbations of COPD - a new biomarker?

C-reactive protein (CRP) and leukocyte count are standard tools for recognising inflammation in COPD patients. This study aimed to find if there is a pattern in monocyte related haematological indices - monocyte to neutrophil ratio (MNR) and monocyte to lymphocyte ratio (MLR) - which could be helpful in differentiating COPD patients in need for hospitalization due to acute exacerbation of COPD or differentiating frequent COPD exacerbators from non-frequent COPD exacerbators. The study included 119 patients with COPD and 35 control subjects, recruited at the Clinic for Respiratory Diseases Jordanovac, University Hospital Centre Zagreb, Croatia.

Platelet Serotonin (5-HT) Concentration, Platelet Monoamine Oxidase B (MAO-B) Activity and , , and Gene Polymorphisms in Asthma.

The complex role of the serotonin system in respiratory function and inflammatory diseases such as asthma is unclear. Our study investigated platelet serotonin (5-HT) levels and platelet monoamine oxidase B (MAO-B) activity, as well as associations with (rs6314; rs6313) (rs3813929; rs518147), and (rs1799836; rs6651806) gene polymorphisms in 120 healthy individuals and 120 asthma patients of different severity and phenotypes. Platelet 5-HT concentration was significantly lower, while platelet MAO-B activity was considerably higher in asthma patients; however, they did not differ between patients with different asthma severity or phenotypes.

Heterogeneity in the use of biologics for severe asthma in Europe: a SHARP ERS study.

Introduction: Treatment with biologics for severe asthma is informed by international and national guidelines and defined by national regulating bodies, but how these drugs are used in real-life is unknown.

Materials And Methods: The European Respiratory Society (ERS) SHARP Clinical Research Collaboration conducted a three-step survey collecting information on asthma biologics use in Europe. Five geographically distant countries defined the survey questions, focusing on seven end-points: biologics availability and financial issues, prescription and administration modalities, inclusion criteria, continuation criteria, switching biologics, combining biologics and evaluation of corticosteroid toxicity.

Variants Are Associated with the Risk for COPD and NSCLC Development, Better Overall Survival of the NSCLC Patients and Increased Chemosensitivity in the H1299 Cell Line.

Chronic obstructive pulmonary disease (COPD) is considered as the strongest independent risk factor for lung cancer (LC) development, suggesting an overlapping genetic background in both diseases. A common feature of both diseases is aberrant immunity in respiratory epithelia that is mainly regulated by Toll-like receptors (TLRs), key regulators of innate immunity. The function of the flagellin-sensing TLR5 in airway epithelia and pathophysiology of COPD and LC has remained elusive.

Activation of NLRP3 inflammasome in stable chronic obstructive pulmonary disease.

Nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation plays an important role in chronic obstructive pulmonary disease (COPD) pathogenesis and might be involved in ongoing chronic inflammation. This study aimed to determine interleukin-1beta (IL-1β) plasma concentration as well as IL1B, NLRP3 and caspase-1 (CASP1) gene expression in the Croatian COPD patients. 109 patients with stable COPD and age- and sex-matched 95 controls were included in the study.

The Influence of Depression, Anxiety and Stress on Changes in Locomotor Parameters in Patients Who Are Prone to Develop COPD.

Background: Depression and anxiety are the most prevalent diseases that contribute to global disability, especially if they are not early recognised and properly treated. They occur as part of many chronic diseases, often remain unrecognised at an early stage, and significantly contribute to the progression of the underlying disease reducing the quality of life in these patients. Numerous studies have shown that anxiety / depression and dyspnea are the leading symptoms in patients with COPD that are associated with high morbidity and mortality.

Increased and Gene Expression and Association of rs6457452 Single Nucleotide Polymorphism with the Risk of Chronic Obstructive Pulmonary Disease in the Croatian Population.

Heat shock protein 70 (Hsp70) engages Toll-like receptors (TLR) 2 and 4 when found in the extracellular compartment and contributes to inflammation in chronic obstructive pulmonary disease (COPD). Since there is growing evidence for the genetic risk factors for COPD, the gene expression of , and was determined, as well as the association between , and single nucleotide polymorphisms, (SNPs) and COPD. The gene expression was assessed in peripheral blood cells of 137 COPD patients and 95 controls by a quantitative polymerase chain reaction (qPCR), while a total of nine SNPs were genotyped by TaqMan allelic discrimination real-time PCR.

Risk factors for nontuberculous mycobacterial pulmonary disease (NTM-PD) in Croatia.

Background: The incidence, geographical distribution and clinical relevance of different nontuberculous mycobacteria (NTM) in Croatia are well described. There are few data on the risk factors for developing NTM pulmonary disease (NTM-PD) in this setting.

Methods: We conducted a retrospective cohort study on all Croatian residents with NTM isolated from respiratory samples in the period from 2006 to 2015 with follow-up to 2018.

Attitudes of Croatian pulmonologists concerning obstacles to earlier, more appropriate use of biologics in severe asthma: Survey results.

Aims: Biologics have been proven efficacious for patients with severe asthma (SA). It is essential to diagnose such individuals correctly. This study was designed to survey pulmonologists to identify barriers to early diagnosis and subsequent appropriate use of biologics for SA in Croatia.

Biomarkers in Different Asthma Phenotypes.

Asthma is the most common respiratory disease. It has multiple phenotypes thatcan be partially differentiated by measuring the disease's specific characteristics-biomarkers. The pathogenetic mechanisms are complex, and it is still a challenge to choose suitable biomarkers to adequately stratify patients, which became especially important with the introduction of biologicals in asthma treatment.

Influence of disease severity, smoking status and therapy regimes on leukocyte subsets and their ratios in stable chronic obstructive pulmonary disease.

Introduction: Blood cells are involved in systemic inflammation in chronic obstructive pulmonary disease (COPD). We aimed to assess differences in leukocyte subsets and their ratios between COPD patients and healthy individuals as well as their association with disease severity, smoking status and therapy in COPD.

Material And Methods: One hundred and nine patients in the stable phase of COPD and 95 controls participated in the study.

Plasma Brain-Derived Neurotrophic Factor (BDNF) Concentration and / Gene Polymorphisms in Croatian Adults with Asthma.

Brain-derived neurotrophic factor (BDNF) and its tropomyosin-related kinase B (TrkB) receptor might contribute to normal lung functioning and immune responses; however, their role in asthma remains unclear. Plasma BDNF concentrations, as well as and ( gene) polymorphisms, were investigated in 120 asthma patients and 120 healthy individuals using enzyme-linked immunosorbent assay and polymerase chain reaction, respectively. The genotype and allele frequencies of Val66Met (rs6265) and rs1439050 polymorphisms did not differ between healthy individuals and asthma patients, nor between patients grouped according to severity or different asthma phenotypes.

Association of Plasma Heat Shock Protein 70 with Disease Severity, Smoking and Lung Function of Patients with Chronic Obstructive Pulmonary Disease.

Extracellular heat shock protein 70 (eHsp70) might modulate immune responses in chronic obstructive pulmonary disease (COPD). The aim of the study was to explore eHsp70 concentration in stable COPD, its association with disease severity and smoking status as well as its diagnostic performance in COPD assessment. Plasma samples were collected from 137 COPD patients and 95 healthy individuals, and concentration of eHsp70 was assessed by commercially available enzyme-linked immunosorbent assay (ELISA) kit (Enzo Life Science, Farmingdale, NY, USA).

Lipid profile and atherogenic indices in patients with stable chronic obstructive pulmonary disease.

Background And Aims: Limited number of studies investigated lipid profile in chronic obstructive pulmonary disease (COPD) with inconsistent results. This study aimed to investigate lipid parameters in sera of patients with stable COPD and their associations with disease severity, smoking, comorbidities and therapy.

THE ROLE OF CIGARETTE SMOKING AND ALCOHOL CONSUMPTION IN PULMONARY TUBERCULOSIS DEVELOPMENT AND RECURRENCE.

During a two-year period (2001-2003), 464 patients were treated for tuberculosis at Jordanovac Department for Lung Diseases in Croatia. Besides pulmonary tuberculosis in 97.7% of patients, patients were also treated for tuberculous pleurisy (0.

Uric acid and uric acid to creatinine ratio in the assessment of chronic obstructive pulmonary disease: Potential biomarkers in multicomponent models comprising IL-1beta.

Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous disease, with oxidative stress and inflammation implicated in its development. Uric acid (UA) could exert anti-oxidative, pro-oxidative or pro-inflammatory effects, depending on the specific context. It was recently shown that soluble UA, and not just its crystals, could activate the nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome, leading to interleukin (IL)-1β secretion.

ABO blood group genotypes and ventilatory dysfunction in patients with allergic and nonallergic asthma.

Aim ABO blood group genotypes are established as a genetic factor in pathophysiology of various diseases, such as cardiovascular disorders, cancers, infectious diseases and there is rising evidence of their involvement in other conditions. The aim of this study was to determine if ventilatory changes of lung function in asthma, measured by biomarkers/parameters, are connected to certain ABO blood group genotypes in Croatia. Methods A case-control study included 149 patients with asthma and 153 healthy individuals (blood donors).
