    Introduction: Endobronchial ultrasonography (EBUS) is an endoscopic method that aids needle aspiration to see the bronchial wall and adjacent tissues with an ultrasound probe. Pulmonary arteries are rarely present between the bronchus wall and the tissue. In this case, it was necessary to make a selection between invasive processes and transbronchial needle aspiration (TBNA) through the pulmonary artery. There are few case reports about the safety of TBNA through the pulmonary artery. We aimed to present the results of EBUS guided TBNA through the pulmonary arteries. Materials and Methods: The data on four cases (three men) in whom EBUS guided TBNA was performed through the pulmonary artery between August 2010 and December 2015 were reviewed retrospectively. Procedures were conducted under local anesthesia and conscious sedation. For TBNA, 22-gauge needles were used. Cases were monitored for 24 hour after the procedures. Antibiotic prophylaxis and onsite cytopathology were not used. Results: All lesions existed were on the left hilar localization. Two of the diagnosed cases were carcinoma and one was the granulomatous lymphadenitis. We were not able to diagnose the last case. No complication was observed in any cases during the procedure. Conclusion: EBUS guided TBNA through the pulmonary arteries at left hilar lesions is safe. The rate of diagnoses from the tissues obtained is high. No special preparation is needed for the cases have no the pulmonary hypertension.

    Evaluation of Serum Biomarkers in Patients with Sarcoidosis: Can Visfatin Be a New Biomarker for Sarcoidosis?

    OBJECTIVES: Sarcoidosis is a chronic systemic inflammatory disease that affects multiple organ systems. The role of biomarkers in the diagnosis and prognosis of sarcoidosis is increasing. Interest in the role of adipose tissue-mediated inflammation in the pathogenesis of inflammatory diseases has increased in recent years. Visfatin is a proinflammatory adipocytokine that has been studied for several inflammatory diseases such as diabetes mellitus, obesity, and metabolic syndrome. We aimed to assess serum visfatin levels in sarcoidosis and its relationship with other markers of inflammation such as C-reactive protein (CRP), angiotensin-converting enzyme (ACE) and erythrocyte sedimentation rate (ESR). MATERIALS AND METHODS: We enrolled 59 patients with sarcoidosis and 21 healthy controls and measured plasma levels of visfatin, along with serum CRP, ESR, and ACE using ELISA (enzyme-linked immunosorbent assay) kits (Blue Gene Biotech, Shanghai, China). RESULTS: Visfatin levels did not differ significantly between the patients and control subjects (29.9 +/- 15.8 ng/mL for patients and 23.93 +/- 16.73 ng/mL for controls, p=0.15), and there was no correlation between visfatin and serum CRP, ACE, or ESR in patients with sarcoidosis. CONCLUSION: Visfatin is recently being discussed as a biomarker for inflammatory diseases in several studies, and results are controversial. In our study, no differences were found in the serum levels of visfatin between patients with sarcoidosis and the control group.

    General features of patients with Pulmonary Langerhans Cell Histiocytosis followed in our instution
    (Turkish Assoc Tuberculosis & Thorax, 2018) Acat, Murat; Tanriverdi, Elif; Ugur Chousein, Efsun Gonca; Demirkol, Baris; Yildirim, Binnaz Zeynep; Turan, Demet; Ozgul, Mehmet Akif
    Introduction: Pulmonary Langerhans Cell Histiocytosis (PLCH) is a rare disease affecting young smokers. It is more common between the ages of 20-40 and equals the male/female ratio. Lung biopsy is the most useful methods for diagnosis. The first treatment is to quit smoking. Corticosteroids or chemotherapeutic agents can be used in severe progressive cases despite of quiting smoking. The patients with PLCH followed in our clinic were assessed with general clinical features in the light of the literature. Materials and Methods: We retrospectively evaluated patients with PLCH in our clinic between January 1999 and June 2017. Results: The female and male distribution of the 21 patients was 11/10. The average age was 35.04 +/- 11.78 years. All patients were active smokers at the time of admission. The most common symptom was dyspnea. The most common finding in the pulmonary function tests was obstructive ventilatory defect. The DLCO value of the 70% patient in the carbonmonooxid diffusion test was below 80%. The most common pathologic findings detected in high-resolution chest tomography (HRCT) were cystic lesions involving bilateral upper and middle areas. There were 3 (14%) patients with pneumothorax at the time of admission and 6 (28.5%) patients with pneumothorax history before. The most common diagnostic method was open lung biopsy. All the patients quit cigarette after the diagnosis. There were 6 patients using steroid therapy, 1 patient receiving steroid and bosentan therapy, and 1 patient made pleurectomy due to recurrent pneumothorax. Lung transplantation was done to patient who received combined bosentan treatment with steroids. Conclusion: PLCH is a rare disease and should be considered in young, smokers with spontaneous pneumothorax and cystic lung disease in the differential diagnosis. As more diffusions are affected in patients, respiratory functions for follow-up should be evaluated with diffusion tests. It is essential to quit smoking in therapy.
