The objective: to determine the involvement of lung mast cell carboxypeptidase A3 (SPA3) in the pathogenesis of COVID-19. Subjects and Methods. Samples of autopsy specimens from the lungs of patients who died of severe COVID-19 and patients who died of external causes were examined. On day 2 after the patient's death, the autopsy was performed and autopsy specimens were collected. Histological samples were prepared to analyze the degranulation activity of CPA3-positive mast cells (MCs). Correlations between protease profile and clinical and laboratory parameters were analyzed.Results. In the patients died of COVID-19, the total numbers of CPA3-positive MCs, CPA3-positive MCs with signs of degranulation, and coadjacent CPA3-positive MCs (two CPA3-positive MCs sharing a common cytoplasm) were statistically significantly higher versus the patients from Control Group. Positive correlations were established between the total number of CPA3-positive MCs and CPA3-positive MCs with signs of degranulation with blood hemoglobin level (r = 0.491; p = 0.008; r = 0.521; p = 0.004), between the total number of CPA3-positive MCs degranulating CPA3-positive MCs and adjacent CPA3-positive MCs with total blood protein (r = 0.431, p = 0.020; r = 0.449, p = 0.015; r = 0.456, p = 0.013), and between CPA3-positive MCs with signs of degranulation and total number of CPA3-positive MCs with aPTT level (r = 0.428; p = 0.021; r = 0.374; p = 0.045). Negative correlations were established between the total number of CPA3-positive MCs and the level of INR (r = 0.812; p = 0.050), separately lying CPA3-positive MCs with the number of monocytes (r = 0.384; p = 0.044), jointly adjacent CPA3-positive Mcs with blood eosinophils (r = 0.420, p = 0.023).

The objective: to assess changes in the data on drug resistance of M. tuberculosis for 2015-2021 and compare it with data for 2012-2014.Subjects and Methods. Using continuous sampling, the frequency of drug resistance of Mycobacterium tuberculosis (MTB DR) was studied in isolates from 151 pulmonary tuberculosis (PTB) patients and isolates from 805 extrapulmonary tuberculosis (EPTB) patients, who were treated at the clinic of St. Petersburg Research Institute of Phthisiopulmonology in 2015-2021. The results were compared with similar data for 2012-2014 which was published in 2016.Results. In 2015-2021 versus 2012-2014, the overall frequency of MTB DR decreased by 4.2% in pulmonary tuberculosis patients (from 90.1 to 85.9%) and by 2.9% in extrapulmonary tuberculosis patients (from 80.2 to 77.4%). The structure of MTB DR in pulmonary tuberculosis changed insignificantly, the frequency of MDR decreased from 42.5 to 36.5%, and XDR (as per the definitions before 2022) remained the same – 39.5%. In extrapulmonary tuberculosis, the structure of MTB DR deteriorated due to lower frequency of MDR (from 66.3 to 48.3%) and higher frequency of XDR (from 3.2 to 19.0%, p<0.01).

The objective: to study the regional prevalence of mycobacteriosis and the types of non-tuberculous mycobacteria causing mycobacteriosis in Mari El Republic and Vladimir Region, to conduct a comparative clinical and radiological analysis of mycobacteriosis and tuberculosis.Subjects and Methods. Cultures of non-tuberculous mycobacteria available in the bank of the bacteriological laboratory of two regions were analyzed: 182 cultures in the Republic of Mari El and 44 cultures in Vladimir Region. Medical records and X-ray archives of patients who were found to be positive for non-tuberculous mycobacteria were retrospectively studied.Results. The incidence of mycobacteriosis in Vladimir Region and Mari El Republic made 1.5 and 4.3 cases per 100,000 population, respectively. Cultures of non-tuberculous mycobacteria that caused mycobacteriosis belonged to diverse species, and M.avium-complex was the most common (76% of cases). There were no statistically significant differences in the location and extent of lesions in patients with mycobacteriosis and tuberculosis (p > 0.05). The frequency of positive results of Mantoux test with 2TU was comparable Positive results of TRA test were found significantly more often among patients with tuberculosis versus patients with mycobacteriosis (15/19 (78.9%) and 9/24 (37.5%), respectively; p < 0.05). However, this is insufficient for differential diagnosis of these diseases.

The course of HIV infection depends on the degree of HIV suppression during ART.The objective: to evaluate feasibility of using three factors: viral load (VL), HIV reservoir and CD8 T cells before ART initiation to estimate future levels of “residual” viremia and develop a predictive model.Subjects and Methods. 74 naive patients with HIV infection were enrolled in the study. The HIV reservoir, VL and CD4, CD8 counts were tested before ART initiation and then every 6 months. The patients were followed up for 12 months. Discriminant analysis was used.Results. After 12 months of ART, 69/74 (93.2%) patients had undetectable VL including 14 patients with residual viremia (RV) and 55 in whom no virus was detected. The probability of persisting RV after 12 months of ART was assessed first by one factor – VL prior to ART, after that by three factors – VL, HIV reservoir (HIV DNA), CD8 count prior to ART. A predictive model formula was generated using those factors: D = -5.288-0.001 CD8+1.342VL+0.08 HIV DNA. With discriminant function D>0.065, the patient has a high probability of RV after 12 months of ART; with D ≤0.065, the probability of RV is low. This prognosis should be taken into account when choosing an ART regimen ensuring its maximum optimization.

This prognosis should be taken into account when choosing an ART regimen ensuring its maximum optimization.","PeriodicalId":37828,"journal":{"name":"Tuberculosis and Lung Diseases","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140230531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective: to evaluate VTEC in new tuberculosis patients and relapses, to determine main factors influencing its development (according to data of the patients admitted to Moscow tuberculosis hospitals)Subjects and Methods. Based on the data of epidemiological tuberculosis monitoring system of Moscow, treatment outcomes of 4609 tuberculosis patients admitted to tuberculosis hospitals from 2020 to 2022 were retrospectively analyzed. The incidence of VTEC was estimated.Results. Totally 214/4609 cases of VTEC were identified (4.6%; 95% CI 4.1-5.3%), among which the incidence of DVT made 3.5% (95% CI 3.0-4.1%), SVP 1.5% (95% CI 1.2-1.9%), and PATE 0.6% (95% CI 0.4-0.8%). The most significant risk factors of thrombotic complications in tuberculosis patients were identified, those factors included HIV infection (RR 3.8; 95% CI 2.7-4.5) and fibrous cavernous form of pulmonary tuberculosis (RR 9.1; 95% CI 4.7-17.6). The overall prevalence of VTEC in tuberculosis hospitals was 3 or more times higher than in general clinics (according to the published data).Conclusion. The data obtained indicate that patients hospitalized for pulmonary tuberculosis face a high risk of VTEC development that requires prediction and prevention.
目的：评估新肺结核患者和复发患者的VTEC，确定影响其发展的主要因素（根据莫斯科结核病医院收治患者的数据）。根据莫斯科结核病流行病学监测系统的数据，对2020年至2022年结核病医院收治的4609名结核病患者的治疗结果进行了回顾性分析。结果。共发现 214/4609 例 VTEC（4.6%；95% CI 4.1-5.3%），其中深静脉血栓的发生率为 3.5%（95% CI 3.0-4.1%），SVP 为 1.5%（95% CI 1.2-1.9%），PATE 为 0.6%（95% CI 0.4-0.8%）。研究发现了肺结核患者血栓并发症最重要的风险因素，包括艾滋病毒感染（RR 3.8；95% CI 2.7-4.5）和纤维空洞型肺结核（RR 9.1；95% CI 4.7-17.6）。结核病医院的 VTEC 总发病率是普通诊所的 3 倍或以上（根据已公布的数据）。所获得的数据表明，因肺结核住院的患者面临着发生 VTEC 的高风险，需要进行预测和预防。
