In recent years, several national chronic obstructive pulmonary disease (COPD) guidelines have been issued. In Serbia, the burden of COPD is high and most of the patients are diagnosed at late stages. Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy is poorly implemented in real-life practice, as many patients are still prescribed inhaled corticosteroids (ICS)-containing regimens and slow-release theophylline. In this document, we propose an algorithm for treating COPD patients in Serbia based on national experts’ opinion, taking into account global recommendations and recent findings from clinical trials that are tailored according to local needs. We identified four major components of COPD treatment based on country specifics: active case finding and early diagnosis in high-risk population, therapeutic algorithm for initiation and escalation of therapy that is simple and easy to use in real-life practice, de-escalation of ICS in low-risk non-exacerbators, and individual choice of inhaler device based on patients’ ability and preferences. With this approach we aim to facilitate implementation of the recommendation, initiate the treatment in early stages, improve cost-effectiveness, reduce possible side effects, and ensure efficient treatment.

Background: Sex hormones are known to have some influence on nasal functions, but their effect on the decongestive response of the nasal mucosa during menstrual cycle is still undetermined. Objectives: The aim of this study was to examine the nasal physiology, the interconnectedness of olfactory and respiratory nasal function and the decongestive response of the nasal mucosa during menstrual cycle. Methods: This study included 101 healthy women aged 23.26 ± 4.81 years with a regular menstrual cycle. The nasal respiratory function and the decongestive response of the nasal mucosa were examined by rhinomanometry. Subjective sense of nasal obstruction and the subjective odor intensity were assessed by standardized questionnaires. The odor identification ability was assessed by Sniffin’ Sticks test. Results: Statistically significant higher values of nasal resistance (0.311 ± 0.107 Pa/cm ³ /s) and NOSE score (11.893 ± 13.83) were observed in the ovulatory phase compared to the luteal (0.281 ± 0.084 Pa/cm ³ /s and 9.029 ± 11.12). An odor identification test score was significantly higher in luteal phase (12.476 ± 1.48) compared to the ovulatory phase (11.971 ± 1.51), opposite of odor intensity. The difference of nasal resistance before and after decongestion was significantly higher in ovulatory phase (0.105 ± 0.097 Pa/cm ³ /s) compared to the luteal (0.084 ± 0.079 Pa/cm ³ /s). Correlation between subjective and objective parameters of the examinated nasal functions was not statistically significant in any menstrual phase. Conclusion: In the population of women studied, total nasal resistance and NOSE score were significantly lower in the luteal phase of the menstrual cycle. Odor identification was significantly higher in the luteal phase but odor intensity significantly higher in the ovulatory phase. The decongestive response of nasal mucosa was better in the ovulatory phase of the menstrual cycle.

Background: Establishing a regional/national/international registry of patients suffering from chronic obstructive pulmonary disease (COPD) is essential for both research and healthcare, because it enables collection of comprehensive real-life data from a large number of individuals. Objective: The aim of this study was to describe characteristics of COPD patients from the Serbian patient registry, and to investigate actual differences of those characteristics among the COPD phenotypes. Methods: The Serbian registry of patients with COPD was established in 2018 at University of Kragujevac, Faculty of Medical Sciences, based on an online platform. Entry in the Registry was allowed for patients who were diagnosed with COPD according to the following criteria: symptoms of dyspnea, chronic cough or sputum production, history of risk factors for COPD and any degree of persistent airflow limitation diagnosed at spirometry. Results: In the Serbian COPD registry B and D GOLD group were dominant, while among the COPD phenotypes, the most prevalent were non-exacerbators (49.4%) and then frequent exacerbators without chronic bronchitis (29.6%). The frequent exacerbator with chronic bronchitis phenotype was associated with low levels of bronchopulmonary function and absolute predominance of GOLD D group. Anxiety, depression, insomnia, hypertension and chronic heart failure were the most prevalent in the frequent exacerbator with chronic bronchitis phenotype; patients with this phenotype were also treated more frequently than other patients with a triple combination of the most effective inhaled anti-obstructive drugs: long-acting muscarinic antagonists, long-acting beta 2 agonists and corticosteroids. Conclusion: In conclusion, the data from the Serbian registry are in line with those from other national registries, showing that frequent exacerbators with chronic bronchitis have worse bronchopulmonary function, more severe signs and symptoms, and more comorbidities (especially anxiety and depression) than other phenotypes. Other studies also confirmed worse quality of life and worse prognosis of the AE-CB phenotype, stressing importance of both preventive and appropriate therapeutic measures against chronic bronchitis.

The primary objectives of asthma management during pregnancy are to achieve adequate symptom control, reduce the risk of acute exacerbations, and maintain normal pulmonary function, all of which contribute to ensuring the health and well-being of both the mother and the baby. The Global Initiative for Asthma (GINA) recommends that pregnant women with asthma continue using asthma medications throughout pregnancy, as the benefits of well-controlled asthma for both the mother and fetus outweigh the potential risks of medication side effects, poorly controlled asthma, and exacerbations. The classification of asthma medications by the US Food and Drug Administration (FDA) into categories A, B, C, D, and X is no longer applied. Instead, the potential benefits and risks of each medication during pregnancy and lactation are considered individually. The use of medications to achieve good asthma control and prevent exacerbations during pregnancy is justified, encompassing inhaled corticosteroids (ICS), some leukotriene receptor antagonists (LTRA), short-acting beta-2 agonists (SABA), long-acting beta-2 agonists (LABA), short-acting muscarinic antagonists (SAMA), long-acting muscarinic antagonists (LAMA), and, recently, biological therapies, even in the absence of definitive safety data during pregnancy.

Background/Aim. Asthma is one of the most common chronic pulmonary diseases. The number of asthmatics has been continuously increasing all over the world. Depending on its causing agent, asthma is classified as allergic and nonallergic. Asthma is often associated with other allergic diseases, and it is most commonly preceded by the symptoms of rhinitis. The aim of this study was to establish the type and frequency of allergic sensitization to inhalatory allergens, frequency of concomitant rhinitis, gender and age-related distribution of asthma, and the presence of some risk factors in patients with diagnosed asthma. Methods. This retrospective and partially prospective analysis included 733 patients with asthma diagnosed in the Institute for Pulmonary Diseases of Vojvodina, Sremska Kamenica over the period January, 2004-December, 2008. The obtained date were statistically processed. Results. Females were significantly more often affected by asthma (p < 0.05), most frequently at 20-29 years of age. A hereditary predisposition to the diseases in terms of atopy was registered in 34.9% of the examined subjects. Most patients had allergic asthma (79.5%). Sensitization to internal and external inhalatory allergens was verified in 77.5% and 67.6% of the patients respectively, and combined hypersensitivity to both allergen types in 48.8% of the patients. Rhinitis was registered in 63.9% and 28% of the patients with allergic and nonallergic asthma, respectively. Rhinitis symptoms preceded the occurrence of asthma in 60% of the patients, with the precedence of rhinitis ranging from 1 to 27 years. A high correlation between rhinitis and asthma was established for the disease of both allergic (r = 0.92) and nonallergic (r = 0.88) etiology. Conclusion. The majority of the patients have allergic asthma, and they are females at 20-29 years of age. Senstization to internal allergens is most common, and then to external ones. Rhinitis is the most common concomitant disease, usually preceding the occurrence of asthmatic symptoms.
