This paper presents the results of the comparative analysis of the taxonomic composition of oropharyngeal microbiota obtained by swab from the back of the throat of the 2 groups of patients with bronchial asthma: patients with mild persistent controlled or partially controlled asthma, and patients with severe uncontrolled asthma. The swab collecting procedure was performed in a stable period of the disease without exacerbations episodes and systemic antibiotic therapy courses within the previous 4 weeks or more. Taxonomic identification of the microbiota was performed using conserved regions of bacterial 16S rRNA sequencing. The study revealed a number of differences in the representation of the identified microorganisms that make up the oropharyngeal microbiota in patients with asthma, depending on the severity of asthma, the level of control, other clinical and anamnestic features.

Abstract Background Lockdown has been enforced globally to curb the spread of SARS-CoV-2. Patients with uncontrolled asthma are at risk of severe illness from COVID-19, highlighting the priority of adequate asthma control during the pandemic. Staying indoors exposes asthmatics to indoor asthma triggers, including disinfectants used for limiting the virus spread, in addition to psychological stresses of the pandemic which represent crucial contributors to loss of asthma control. Elective medical care, curtailed by the lockdown procedures, compromises adequate asthma follow up. The current study evaluated the effect of COVID-19 lockdown on the level of asthma control and mental health of bronchial asthma patients. The study included 264 bronchial asthma patients, aged 12 years and older, who responded to an online questionnaire including the asthma control test to evaluate asthma control in the preceding 4 weeks. Anxiety and depression scores and the impact of event scale were also provided. Results Seventy percent of asthmatics had uncontrolled asthma, and disinfectant use was associated with perceived increase in asthma symptoms in 77.7%. Anxiety and depression were associated with uncontrolled asthma in 50% of participants, suggesting a possible psychological impact on asthma patients. Conclusions During lockdown, asthma patients participating in the study had significantly uncontrolled disease and associated anxiety and depression. Since regular follow-up of asthma patients is cornerstone to adequate asthma control, alternative methods of medical care for asthma patients during lockdown are warranted, and particular need for mental health support ought to be provided as a continuum to adequate asthma control.

Bronchial asthma is a chronic disease that can affect in any ages in developed country. In 2016 there were 339,4 million people around the world got asthma. According to Basic Health research 2018, the prevalence of asthma in Indonesia was 2,4% of the population and Lampung province was the highest affected in the last 12 months. The level of asthma control is the extent to which the characteristics of asthma can be observed in patients with asthma and have been reduced or disappear with treatment. Uncontrolled asthma caused by various factors, for example is exposure of cigarette smoke. The study aim to find out the correlations between the exposure of cigarette smoke for the level of asthma control in patients with bronchial asthma at Harum Melati Clinic of Pringsewu on period of August 2018-August 2019. This analytic study  used a retrospective approach. Total sampling technique used with sample of 308 medical records that meet the inclusion criteria and exclusion criteria. Data from this research analyzed by Spearman test. In this study, 83 (26.9%) subjects had uncontrolled asthma, 225 (73.1%) subjects having controlled asthma, and there are no asthma patients have well controlled asthma (0%). 152 (49.4%) subjects not exposed of cigarette smoke and 156 (50.6%) subjects exposed of cigarette smoke.  There is a correlations between the exposure of cigarette smoke for the level of asthma control in patients with bronchial asthma at Harum Melati Clinic of Pringsewu on period of August 2018-August 2019.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a disease with still not enough known pathogenesis despite the development of genetics, immunological and microbiological research. The number of patients with CRS has been constantly growing. The coexistence of CRS, bronchial asthma and aspirin intolerance (aspirin triad) is an adverse prognostic factor with higher risk of recurrences. The aim of study was to compare the severity of CRSwNP depending of coexistence of bronchial asthma and/or aspirin intolerance. The research was performed in the group of 204 patients operated 2009-2013 with 5 years follow-up. Higher nasal polyps growth in groups of patients with aspirin triad and CRSwNP and bronchial asthma in endoscopic examination (p=0,0005 and p=0,0030 respectively) and CT-scan according to Lund-Mackay point scale (p<0,0001 and p=0,0009) was showed. Also, these patients presented increased severity of nasal symptoms before surgical treatment according to VAS scale (p=0,0126 for CRSwNP with bronchial asthma; p=0,0390 for aspirin triad). Similarly, 6 months after surgery the same groups of patients presented higher severity of the disease symptoms (p<0,0001 for aspirin triad’ patients; p=0,0174 for CRSwNP and bronchial asthma’ patients) . Patients with aspirin triad had also statistically more surgeries in past (p=0,001), what proves that recurrences in this group are very likely to be observed in spite of the use of proper conservative treatment. No such differences have been shown in the group of patients with CRSwNP and isolated aspirin intolerance (without bronchial asthma). Allergy to inhaled allergens, hypersensitivity to aspirin are factors significantly worsening the course of CRSwNP. It would be advisable to consider, despite a lack of history of aspirin intolerance, a hypersensititvity to aspirin test in patients with particularly severe CRSwNP, especially those associated with bronchial asthma. It also seems reasonable to carry out such a test on every patient with newly diagnosed CRSwNP and bronchial asthma in order to be able to plan further treatment in this group of patients accordingly including biological treatment with antimonoclonal therapy against interleukin 4, 5 or13.

 Aim. The study of the prevalence and clinical peculiarities of Mycoplasmosis and Chlamydiosis in patients with different pathogenic forms of bronchial asthma (BA) taking into account ethnicity of a patient. Subjects and Methods. The research covered 239 subjects – both the Europeoids and the Mongoloids in the city of Krasnoyarsk and the town of Kyzyl, all of them being BA patients of different stages, including acute stage and practically healthy. We had determined antigens Mycoplasma pneumoniae, Mycoplasma hominis, Chlamydophila pneumoniae, Chlamydophila psittaci and Chlamydia trachomatis in smears of mucosa of pharynx and antibodies to these antigens in peripheral blood serum. Results.  We found high frequency of Mycoplasmosis and Chlamydiosis in the inhabitants of Eastern Siberia, BA patients with different pathogenic forms as compared to control group. We had determined ethnic peculiarities of specific immune response: IgM to М. pneumoniae was revealed in the Europoids more frequently than in the Mongoloids, but IgM to С. pneumoniae and to C. trachomatis, C. trachomatis antigens had been revealed more often in the Mongoloids than in the Europoids. We accepted as clinical equivalents of Mycoplasmosis and Chlamydiosis diagnostics the following signs: temperature around 37C (subfebrile temperature), non-intensive but stable coughing with scanty mucous and muco-purulent sputum, dyspnea of mixed character. Conclusions. Mycoplasma and Chlamydia are meaningful etiologic factors of bronchial asthma. We have found the peculiarities of immune response depending on ethnicity of a patient (ethnic belonging). Clinical markers of Mycoplasmosis and Chlamydiosis should be taken into account in bronchial asthma in order to provide diagnostics timely as well as eradication of infection agents. Because of insufficient knowledge of problem of bronchial asthma related to contamination with Мycoplasma and Chlamydia we put the goal to study the frequency of Mycoplasmosis and Chlamydiosis occurrence in bronchial asthma patients and determine the characteristics clinical course of diseases. We defined antigens Мycoplasma pneumoniae, Мycoplasma hominis, Chlamydophila pneumoniaе, Chlamydophila psittaci, Chlamydia trachomatis in smears of oropharynx mucosa and antibodies to them in blood serum.

Bronchial asthma is a multifactorial disease, with both environmental factors and genetic predisposal affecting its development. A number of gene associations have been obtained between polymorphisms of cytokine genes produced by different types of immune cells and asthma development. Interleukin-13 is involved in allergic inflammation, increased bronchial hypersensitivity, regulation of eosinophil levels and IgE production by B cells, thus making it promising for studying IL13 gene polymorphisms in bronchial asthma coupled to development of the disease. The aim of this study was to investigate possible association between asthma and IL13 rs1800925 polymorphism in the children of Caucasian origin in Eastern Siberia. Four groups of patients with asthma were examined (mean age 12.8±1.2 years): with a controlled (n = 95) and uncontrolled course (n = 107), with severe (n = 71) and moderate severity (n = 131) diseases. The control group consisted of healthy individuals: children (n = 33) and adults (n = 102). DNA was isolated with sorbent method; genotyping was carried out using RT-PCR using specific oligonucleotide primers and fluorescent TaqMan probes. The allele and genotype frequencies were compared by the χ-square test using an online calculator. The odds ratio (OR) with a 95% confidence interval (CI) was performed to link genetic markers with pathological phenotypes. The CT IL13 rs1800925 genotype was shown to be associated with moderate asthma and cases of uncontrollable clinical course, whereas the TT genotype was associated with severe asthma. Thus, rs1800925 polymorphism of IL13 gene (the T* variant is known to be associated with increased IL-13 expression) may be associated with bronchial asthma in children. Our data are consistent with results of other authors. E.g., Liu Z. et al. revealed an association between rs1800925 IL13 and the risk of developing asthma in children, with CT and TT genotypes being more common in the patient group. Radhakrishnan A. et al., was studied rs1800925 IL13 in adult population of Malaysia and found that the T* allele frequency in the group of patients significantly exceeds the frequency of this allele in the control group. Thus, the results of our study showed that IL13 rs1800925 polymorphism is associated with bronchial asthma in children, especially, with level of its control and severity of the disease.

Background: Recent studies have reported the epidemiological link between Metabolic Syndrome (MS) and asthma, but it has rarely been studied in Egypt. The study aimed to investigate the prevalence of MS and its predictors among asthma patients in Egypt. Methods: In total, 320 patients with bronchial asthma were included. The following were assessed: spirometric evaluation, anthropometric indices, blood pressure, fasting blood sugar and serum lipid profile. We analyzed the correlation between metabolic scores and patient characteristics. Predictors of MS were identified using logistic regression analysis. Results: The prevalence of MS was 57.5% in asthma patients. For asthma patients, low High-Density Lipoprotein (HDL) and abdominal obesity were the commonest metabolic abnormality. Waist circumference, Fasting Blood Sugar (FBS) and triglyceride correlated significantly with asthma (P ‹ 0.05). FBS and DBP were the best predictors of MS. Conclusion: MS is frequent in asthma patients in Egypt. Obesity and lipid abnormalities were the commonest metabolic abnormality. Screening of these patients for components of metabolic syndrome should be a part of routine workup.
