Contemporary Diagnostics of Cardiac Sarcoidosis: The Importance of Multimodality Imaging.

Sarcoidosis is an inflammatory condition that can affect multiple organ systems and is characterized by the formation of non-caseating granulomas in various organs, including the heart. Due to suboptimal diagnostic rates, the true prevalence and incidence of cardiac sarcoidosis (CS) remain to be determined. In patients with suspected CS, an initial examination should include 12-lead ECG or ambulatory ECG monitoring, and echocardiography with the estimation of LV, RV function, and strain rate.

Characteristics of Patients with Sarcoidosis with Emphasis on Acute vs. Chronic Forms-A Single Center Experience.

Sarcoidosis is a granulomatous disease of unknown etiology that can affect almost any organ. Although the acute form can have spontaneous regression, a certain number of patients can have a chronic form, which leads to an increase in mortality and a decrease in the quality of life. Considering that the risk factors are still unknown, we wanted to compare the characteristics of patients with acute and chronic forms of sarcoidosis in Serbia in order to determine significant differences between them with hopes of contributing to everyday clinical practice.

The usefulness of MMP-9, TIMP-1 and MMP-9/TIMP-1 ratio for diagnosis and assessment of COPD severity.

Background: Inflammation, oxidative stress and an imbalance between proteases and protease inhibitors are recognized pathophysiological features of chronic obstructive pulmonary disease (COPD). The aim of this study was to evaluate serum levels of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in patients with COPD and to assess their relationship with lung function, symptom severity scores and recent acute exacerbations.

Methods: In this observational cohort study, serum levels of MMP-9 and TIMP-1 and the MMP-9/TIMP-1 ratio in the peripheral blood of COPD patients with stable disease and healthy controls were determined, and their association with lung function (postbronchodilator spirometry, body plethysmography, single breath diffusion capacity for carbon monoxide), symptom severity scores (mMRC and CAT) and exacerbation history were assessed.

Large-Vessel Giant Cell Arteritis following COVID-19-What Can HLA Typing Reveal?

Giant cell arteritis (GCA) is an immune-mediated vasculitis that affects large arteries. It has been hypothesized that viruses may trigger inflammation within the vessel walls. Genetic studies on human leukocyte antigens (HLAs) have previously reported HLA-DRB1*04 as a susceptible allele for GCA and HLA-DRB1*15 as a protective allele for GCA.

Diagnosis and treatment of adult asthma patients in Serbia: a 2022 experts group position statement.

Introduction: Asthma is the most common non-communicable chronic lung condition across all ages. Epidemiological data indicate that many asthma patients in Serbia remain undiagnosed and untreated. The implementation of recent global advances in asthma management is limited due to the lack of a systematic approach, drug availability and regulatory affairs.

Autoimmune and immunoserological markers of COVID-19 pneumonia: Can they help in the assessment of disease severity.

Background: Immune dysregulation and associated inefficient anti-viral immunity during Coronavirus Disease 2019 (COVID-19) can cause tissue and organ damage which shares many similarities with pathogenetic processes in systemic autoimmune diseases. In this study, we investigate wide range autoimmune and immunoserological markers in hospitalized patients with COVID-19.

Methods: Study included 51 patients with confirmed Severe Acute Respiratory Syndrome Coronavirus 2 infection and hospitalized due to COVID-19 pneumonia.

A randomized, double-blind, placebo-controlled study evaluating the efficacy of propolis and N-acetylcysteine in exacerbations of chronic obstructive pulmonary disease.

Objective: Acute exacerbations of chronic obstructive pulmonary disease (AECOPDs) accelerate the progressive impairment of lung function and general health. Together with maintenance therapy for chronic obstructive pulmonary disease (COPD), N-acetylcysteine (NAC) and natural propolis have demonstrated pharmacological properties that address crucial pathophysiological processes underlying COPD and may prevent AECOPDs. This study aims at responding to dose-dependent efficacy and safety concerns regarding a propolis-NAC combination for the reduction of COPD exacerbation rates.

Acute "Pseudoischemic" ECG Abnormalities after Right Pneumonectomy.

New onset of electrocardiographic (ECG) abnormalities can occur after lung surgery due to the changes in the position of structures and organs in the chest cavity. The most common heart rhythm disorder is atrial fibrillation. So-called "pseudoischemic" ECG changes that mimic classic ECG signs of acute myocardial ischemia are also often noticed.
