Aim: Our aim was to study and analyze the level of the annexin V apoptosis marker in the oral fluid in patients with generalized periodontitis without general somatic pathology and against the background of bronchiectasis.Materials and methods. 40 patients diagnosed with generalized periodontitis without somatic pathology and 50 patients diagnosed with generalized periodontitis and bronchiectasis were examined. The control group included 40 somatically healthy individuals with intact periodont. Indices characterizing the state of periodontal tissues, such as PMA, PI, Muhlemann, OHI-s were determined for all the examined persons. The level of the annexin V apoptosis marker was determined in the oral fluid by enzyme immunoassay.Results. It was established that the value of the indices of periodontal tissues (PMA, PI, Muhlemann, OHI-s) was statistically signifi cantly higher in the group of patients with generalized periodontitis against the background of bronchiectasis both in comparison with the control group and with the group of patients without general somatic pathology. The level of the annexin V apoptosis marker was also statistically signifi cantly higher in patients with generalized periodontitis against the background of bronchiectasis as compared with the control group and the group of patients without general somatic pathology (p<0.001). According to the correlation analysis, statistically signifi cant relationships of the moderate strength between the level of annexin V and the value of the indices of periodontal tissues were found both in the group of patients without general somatic pathology and in the group of patients with generalized periodontitis against the background of bronchiectasis. At the same time, the strength of these relationships in patients with generalized periodontitis against the background of bronchiectasis was greater as compared to the group of patients without general somatic pathology.Conclusion. The level of the annexin V apoptosis marker in the oral fluid of patients with generalized periodontitis against the background of bronchiectasis is statistically signifi cantly higher (p<0.001) than in patients with generalized periodontitis without general somatic pathology. The results of the correlation analysis indicate the presence of relationships between the level of annexin V and the value of periodontal tissue condition indices (PMA, PI, Muhlemann, OHI-s). Thus, increased apoptosis in generalized periodontitis against the background of bronchiectasis can act as a factor aggravating the damage to periodontal tissues.

Aim. To analyse the level of oxidative stress markers and the value of dental indices characterising the state of periodontal tissue in patients with generalised periodontitis (GP) both without somatic pathology and with bronchiectasis.Materials and methods. Over the period from 2015 to 2017, a total of 90 GP patients were examined, including 40 patients without somatic pathology and 50 patients with bronchiectasis. The control group consisted of somatically healthy individuals with intact periodontium (n=40). The following indices were calculated for all examined individuals: PMA, PI, Muhlemann and OHI-s. The level of oxidative stress markers in oral fl uid was determined: total superoxide dismutase (SOD) of all three types (Cu/Zn-SOD + Mn-SOD + Fe-SOD), products of advanced protein oxidation and malondialdehyde.Results. The study established the intensifi cation of oxidative stress in GP patients without somatic pathology and with bronchiectasis. Patients with comorbid pathologies demonstrated a greater severity of oxidative stress. The analysis revealed a significant correlation between the values of dental indices (PMA, PI, Muhlemann, OHI-s) and the level of oxidative stress markers both in GP patients without somatic pathology and with bronchiectasis. Furthermore, this correlation is stronger in patients with comorbid pathologies.Conclusion. The presence of comorbid pulmonary pathologies in the form of bronchiectasis in patients with generalised periodontitis can act as an aggravating factor in the development of periodontal lesions.

Aim. In this study, the authors set out to find the correlation between the data of cone beam computed tomography (CBCT) and the levels of inflammatory markers in patients with chronic generalised periodontitis (CGP), both without somatic pathology and with bronchiectasis.Materials and methods. The study included 90 CGP patients and 40 somatically healthy individuals with intact periodontium. CGP patients were divided into two groups: CGP patients without somatic pathology (n = 40) and CGP patients with bronchiectasis (n = 50). Using ELISA, the authors determined the level of the following inflammatory markers in oral fluid: transforming growth factor beta 1 (Tgfß-1), interleukin -8 (IL-8), lactoferrin (LF) and C-reactive protein (CRP).Results. The analysis of CBCT data and the levels of inflammatory markers (Tgfß-1, LF, IL-8 and CRP) revealed that more pronounced changes in their values were observed in CGP patients with bronchiectasis. In addition, the revealed correlations between CBCT data and the levels of inflammatory markers in CGP patients without somatic pathology and CGP patients with bronchiectasis indicate a relation between the severity of inflammatory reaction and the clinical manifestations of CGP. Furthermore, this correlation is stronger in CGP patients with comorbid pathology than in CGP patients without somatic pathology.Conclusion. The presence of comorbid pathology in the form of bronchiectasis in CGP patients has a negative impact on the periodontium, which should be considered when managing patients.

Background. The study of the features of the course and the general links of pathogenesis in patients with chronic generalized periodontitis (CGP) with comorbid pathology is one of the priorities of modern medicine. Objectives ― to assess and analyze the level of apoptosis marker annexin A5 and the value of dental indices in patients with CGP of varying severity without General somatic pathology and against the background of bronchiectatic disease Methods. The study involved 90 patients with present study included varying degrees (light, medium, heavy), which were divided into two groups: patients with no somatic pathology (n=40) and patients with comorbid pathology in the form of bronchoectatic disease (n=50). Somatically healthy individuals with intact periodontal disease (n=40) were examined as a control group. The values of dental indices – PMA, PI, Muhlemann and OHI-s. The level of annexin A5 was determined in the oral fluid by enzyme immunoassay. Results. In patients with CGP revealed a statistically significant higher value of the level of annexin A5 compared with somatically healthy individuals with intact periodontal and statistically significantly higher in patients with more severe periodontitis. At the same time, in patients with comorbid pathology, the level of annexin A5 in patients with CGP with bronchoectatic disease with mild, average and heavy degree of periodontitis is statistically significantly higher than in patients with CGP without somatic pathology. The revealed relationships between the value of dental indices and the level of annexin A5 indicate the influence of the studied marker of apoptosis on the state of periodontal tissues. Moreover, the patients with comorbidity the power value of the identified links more than the present study included patients with no somatic pathology. Conclusion. The obtained data show the influence on the currents present study included the presence of comorbid pathology in the form of bronchoectatic disease and presence of common mutually aggravating link of pathogenesis of apoptosis and the opportunity to use annexin A5 as predictive marker of progression, as the present study included patients with no somatic pathology and in the background bronchoectatic disease.
