Medical thoracoscopy without pleural fluid: How I do it.

Thoracoscopy is a commonly used minimally invasive procedure in the field of interventional pulmonology. While medical thoracoscopy is the widely preferred modality, modifications to the technique and expansion in the scope of its utility have always challenged the conventional approach. We describe a modified technique of medical thoracoscopy in absence of pleural effusion also known as dry thoracoscopy under sedation and local anaesthesia.

A case report on expanding horizon of endobronchial ultrasound through esophagus.

Endobronchial ultrasound has revolutionized the field of bronchoscopy and has become one of the most important tools for the diagnosis of intrathoracic lymphadenopathy and para-bronchial structures. The reach of this technique has not been limited to these structures and pleural lesions have been at times accessible. To our knowledge, pleural fluid collections have not been accessed with endobronchial ultrasound (EBUS) through oesophageal approach and rationale behind using this approach. We report a case of 70 years old man who has been referred from physician for the EBUS in view of hilar mass with mediastinal lymphadenopathy with pleural effusion. The endobronchial ultrasound through oesophagus (EUS-B) was done for thoracocentesis and lymph node cytology evaluation and ultimately endobronchial biopsy of hilar mass was done as rapid on-site (ROSE) analysis of lymph node was suggestive of necrotic tissue. The cytology report of lymph node and pleural effusion was positive for malignant cells. The final diagnosis was metastatic poorly differentiating adeno-squamous carcinoma.

Pirfenidone in Idiopathic Pulmonary Fibrosis: Real-World Observation on Efficacy and Safety, Focus on Patients Undergoing Antithrombotic and Anticoagulant.

Idiopathic pulmonary fibrosis (IPF) is a rare and progressive interstitial lung disease characterized by irreversible distortion of lung architecture and subsequent loss of pulmonary function. Pirfenidone is an antifibrotic agent associated with increased progression-free survival and overall survival rates, but it carries multiple side effects. The aim of the study was to examine the efficacy and safety profile of pirfenidone in a real-life context, with a focus on the concomitant use of antithrombotic and/or anticoagulant treatments. The clinical and functional data (forced vital capacity [FVC], forced expiratory volume in 1 s [FEV1], diffusing lung capacity for carbon monoxide [DLCO], and 6 min walking test distance [6MWD]) of all IPF patients treated with pirfenidone and referred to our two centers between 2019 and 2022 were retrospectively analyzed at baseline, 6 and 12 months after the start of treatment. A total of 55 IPF subjects undergoing pirfenidone treatment were included in the analysis (45.5% females, median [IQR] age at disease onset 68.0 [10.0] years, median [IQR] age at baseline 69.0 [10.8] years). Compared to baseline, at 12 months, FVC (86.0% vs. 80.0%; p = 0.023) and DLCO (44.0% vs. 40.0%; p = 0.002) were significantly reduced, while FEV1 (p = 0.304) and 6MWD (p = 0.276) remained stable; no significant change was recorded at 6 months. Most of the reported adverse events were mild or moderate. Gastrointestinal intolerance (9.1%) was the main cause of treatment discontinuation. A total of 5% of patients reported at least one minor bleeding event, although all episodes occurred in those receiving concomitant antithrombotic or anticoagulant. Overall, this real-life experience confirms the efficacy and safety profile of pirfenidone in the case of the concomitant use of antithrombotic and/or anticoagulant drugs.

Esophageal ultrasound with ultrasound bronchoscope (EUS-B) guided transvascular needle aspiration (TVNA).

We have described a 67-year-old man, diagnosed to have adenocarcinoma of lung by transvascular approach with esophageal ultrasound using ultrasound bronchoscope (EUS-B). To the best of our knowledge this is the first case where EUS-B has been used for transvascular fine needle aspiration cytology to diagnose lung carcinoma.

Bosentan for patients with chronic thromboembolic pulmonary hypertension.

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a progressive disease leading to worsening functional status and reduced survival for those patients who cannot undergo pulmonary endarterectomy (PEA). Pharmacotherapy with novel drugs for pulmonary hypertension may be useful in treating patients who are poor candidates for surgery, but there are still few clinical data on medical therapy for CTEPH. The aim of this prospective open-label, multicenter, study is to compare the efficacy of 1-year bosentan treatment to standard drugs in nonoperated patients with CTEPH. PATIENTS AND METHODS: Thirty-four nonoperated patients with CTEPH were enrolled. Functional assessment included 6 minute walk test (6MWT), Borg index, WHO classification, arterial blood gases and echocardiography systolic pulmonary artery pressure (sPAP). Seventeen patients received bosentan (62.5 mg b.i.d. for 4 weeks and then 125 mg b.i.d.); 17 patients were treated with standard therapy alone. RESULTS: At admission sPAP was 76.18+/-5.96 mmHg in bosentan group and 71.48+/-3.71 mmHg in controls, p(a)O(2) 64.68+/-2.25 mmHg in bosentan group, and 59.52+/-2.05 mmHg in controls, 6MWT 297.53+/-34.25 mt in bosentan group, and 268.47+/-36.54 mt in controls. After 12 months there were significant differences between the groups in the 6MWT (+57.24+/-22.21 m vs -73.13+/-21.23 m, p<0.001), dyspnoea index (Borg score 4.29+/-0.49 vs 7.06+/-0.32, p<0.001) and oxygenation (p(a)O(2) 65.93+/-3.76 mmHg vs 48.48+/-1.31 mmHg, p<0.001). The sPAP was stable after 12 months of bosentan (76.18+/-5.96 mmHg vs 71.00+/-5.41 mmHg, p=0.221) in contrast to controls (71.48+/-3.71 mmHg vs 80.44+/-4.70 mmHg, p=0.029). CONCLUSION: The data of this open-label study in nonoperated CTEPH patients suggest an improvement in functional outcomes adding Bosentan to diuretics and oral anticoagulants. No improvement was observed using only standard drugs after 1-year.
