BACKROUND: Malignant mesothelioma (MM) is a fatal neoplasm which frequently results from exposure to asbestos or erionite.

The precise clinical manifestations of tuberculosis are likely to result from a complex interaction between the host and the pathogen. We took serum samples from a group of patients with a variety of clinical and radiological stages of pulmonary tuberculosis in order to characterize tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4) and soluble interleukin-2 receptor (sIL-2R) response. We further evaluated whether the levels of TNF-α, IL-4 and soluble IL-2R are related with each other, and also evaluated the levels of TNF-α, IL-4 and sIL-2R after anti-tuberculosis therapy and relation with radiologic scores. Forty-three inpatients with active pulmonary tuberculosis and 19 healthy controls participated in the study. Patients were divided into four categories radiologically on chest X-ray (minimal, moderate-advanced, far-advanced and with miliary infiltration). Concentrations of TNF-α (20.9±10/15.4±8 pg/ml) and sIL-2R (2569±842/1444±514 pg/ml) were statistically different between patients and controls (p=0.02 and p=0.0001, respectively). Before chemotherapy there was a positive correlation between TNF-α and sIL-2R (r=0.34), but there was no correlation between IL-4 and TNF-α, and between IL-4 and sIL-2R (r=−0.23 and r=−0.22). The TNF-α level was not statistically different in four groups before and after chemotherapy. Results of this study provided some evidence confirming the previously reported role of TNF-α, IL-4 and sIL 2R in the control of tuberculosis, but these cytokines were not found related with disease severity.

Background. Proinflammatory cytokines are prime candidates as causative agents of the metabolic changes that eventually result in tuberculosis-associated weight loss. Microbial products and cytokines such as TNF and IL-1 increase leptin expression dose dependently in adipose tissue. Leptin plays an important role in cellular immunity. Objectives. In this study, we investigated serum leptin and TNF-α levels before and after antituberculosis therapy in patients with active pulmonary tuberculosis (TB). Methods. Twenty five in patients with active pulmonary TB and 18 healthy controls participated in the study. Leptin and TNF-α levels were measured before treatment and six months after the treatment and they were compared with the control group. Body mass index (BMI) and chest X-rays before and after the treatment were also evaluated. Results. The leptin levels before and after the treatment were 1.66±1.68 ng/mL and 3.26±3.81 ng/mL, respectively. The leptin levels of tuberculous patients were significant than in healthy patients (P

Bacille Calmette-Guerin (BCG) has been used extensively as a vaccine against human tuberculosis. Herein, we describe gluteal tuberculosis abscess due to inadvertently injected BCG a patient with bladder cancer.

Objective: Coronavirus disease 2019 (COVID-19) has affected the whole world and caused the death of more than 6 million people. The disease has been observed to have a more severe course in patients with chronic lung diseases. There are limited data regarding COVID-19 in patients with bronchiectasis. The aim of this article is to investigate the course of COVID-19 and factors affecting the clinical outcome in patients with bronchiectasis. Material and Methods: This study was conducted using the Turkish Adult Bronchiectasis Database (TEBVEB) to which 25 centers in Türkiye contributed between March 2019 and January 2022. The database consisted of 1035 patients, and COVID-19-related data were recorded for 606 patients. Results: One hundred nineteen (19.6%) of the bronchiectasis patients (64 female, mean age 57.3 ± 13.9) had COVID-19. Patients with bronchiectasis who developed COVID-19 more frequently had other comorbidities (P = .034). They also more frequently had cystic bronchiectasis (P = .009) and their Bronchiectasis Severity Index was significantly higher (P = .019). Eighty-two (68.9%) of the patients who had COVID-19 were followed up in the outpatient clinic, 27 (22.7%) in the inpatient ward and 10 (8.4%) patients in the intensive care unit. There tended to be a higher percentage of males among patients admitted to the hospital (P = .073); similarly, the mean age of the patients admitted to the hospital was also higher (60.8 vs 55.8 years for the outpatients), but these differences did not reach statistical significance (P = .071). Conclusion: In conclusion, this study showed that severe bronchiectasis, presence of cystic bronchiectasis and worse Bronchiectasis Severity Index are associated with the development of COVID-19, but not with the severity of infection.

Background: Bronchiectasis is a chronic lung disease characterized by permanent bronchial wall dilatation. Although it has been known as an orphan disease, it has recently gained attention because of registry-based studies and drug research. Aims: We aimed to use a multicenter database to analyze and compare data regarding the etiology, associated comorbidities, microbiological characteristics, and preventive strategies of bronchiectasis in Türkiye to those of other countries. Study Design: A multicenter prospective cohort study. Methods: The multicenter, prospective cohort study was conducted between March 2019 and January 2022 using the Turkish Adult Bronchiectasis Database, in which 25 centers in Türkiye participated. Patients aged > 18 years who presented with respiratory symptoms such as cough, sputum, and dyspnea and were diagnosed with non-cystic fibrosis bronchiectasis using computed tomography were included in the study. Demographic information, etiologies, comorbidities, pulmonary functions, and microbiological, radiological, and clinical data were collected from the patients. Results: Of the 1,035 study participants, 518 (50%) were females. The mean age of the patients was 56.1 ± 16.1 years. The underlying etiology was detected in 565 (54.6%) patients. While postinfectious origin was the most common cause of bronchiectasis (39.5%), tuberculosis was identified in 11.3% of the patients. An additional comorbidity was detected in 688 (66.5%) patients. The most common comorbidity was cardiovascular disease, and chronic obstructive pulmonary disease (COPD) and bronchiectasis was identified in 19.5% of the patients. The most commonly detected microbiological agent was Pseudomonas aeruginosa (29.4%). Inhaled corticosteroids (ICS) were used in 70.1% of the patients, and the frequency of exacerbations in the last year was significantly higher in patients using ICS than in nonusers (p < 0.0001). Age [odds ratio (OR): 1.028; 95% confidence interval (CI): 1.005-1.051], cachexia (OR: 4.774; 95% CI: 2,054-11,097), high modified medical research council dyspnea scale score (OR: 1,952; 95% CI: 1,459-2,611), presence of chronic renal failure (OR: 4,172; 95% CI: 1,249-13,938) and use of inhaled steroids (OR: 2,587; 95% CI: 1,098-6,098) were significant risk factors for mortality. Mortality rates were higher in patients with COPD than in those with no COPD (21.7-9.1%, p = 0.016). Patients with bronchiectasis and COPD exhibited more frequent exacerbations, exacerbation-related hospitalizations, and hospitalization in the intensive care unit in the previous year than patients without COPD. Conclusion: This is the first multicenter study of bronchiectasis in Türkiye. The study results will provide important data that can guide the development of health policies in Türkiye on issues such as infection control, vaccination, and the unnecessary use of antibiotics and steroids.

Background: Direct oral anticoagulants (DOACs) have been used in acute pulmonary thromboembolism as an alternative to warfarin due to drug interactions, narrow therapeutic range, and necessary close International Normalized Ratio (INR) monitoring. Phase 3 study results have reported that these drugs are at least as effective as warfarin and beneficial in terms of bleeding; however, studies that present up-to-date life data are necessary. Aims: To evaluate the frequency of using DOACs, which are prescribed with a limited number of indications in our country, and real-life data results. Study Design: Cross-sectional study Methods: This cross-sectional survey collected the clinical data (history, current treatment, treatment duration, etc.) of patients with pulmonary thromboembolism and who applied to the physician for follow-up between October 15, 2019, and March 15, 2020. The researchers kept the patient records sequentially. Results: Data from 836 patients with acute pulmonary thromboembolism from 25 centers were collected, and DOAC was used in 320 (38.5%) of them. The most preferred DOAC was rivaroxaban (n = 294, 91.9%). DOAC was mostly preferred because it could not provide an effective INR level with warfarin (n=133, 41.6%). Bleeding was observed in 13 (4%) patients. Conclusion: The use of direct oral anticoagulants is becoming almost as widespread as conventional therapy. Real-life data results are important for their contribution to clinical practice.
