Active clinical trials for "Hemoptysis"

Some of the risk factors for bleeding following bronchoscopy is having a malignancy or an immunocompromised state. The etiology of this remains uncertain. The investigators suspect that individuals with malignancy have abnormalities involving certain factors that influence the coagulation pathway. The investigators plan to measure these factors prior to and after bronchoscopy.

Hemoptysis is one of the serious complication of many pulmonary diseases. Upto now, there is no proven medical treatment in recurrence of hemoptysis. The investigators will conduct a randomized, placebo controlled trial of tranexamic acid, which can reduce the recurrence of hemoptysis.

Microbiome in lower respiratory diseases is not sufficiently known yet. The objective of this study is to investigate microbiome in patients who present with hemoptysis, and those with pulmonary tuberculosis, non-tuberculous mycobacterial pulmonary disease (NTM-PD), and lung cancer, analyzing respiratory specimen acquired by bronchoscopic approach.

The primary aim is to develop a software algorithm that has the capacity to detect the normal 18 anatomical structures of the lung by using the position of the scope during the bronchoscopy procedure and using existing bronchoscopy technology.

Haemoptysis is the coughing up of blood originating from the respiratory tract. It is a common and worrying clinical symptom which can be due to different aetiologies including lung cancer, tuberculosis, COPD, bronchiectasis, pneumonia, acute bronchitis or unknown origin (cryptogenic haemoptysis). Epidemiology and optimal diagnostic approach are largely unclear. Aims of this study are to define current epidemiology and to provide the best diagnostic approach by providing a diagnostic algorithm.

Estimation of the incidence of pulmonary embolism in patients presenting to the Emergency Department with hemoptysis.

This study will determine the outcomes of anatomic lung resections in patients who recovered from coronavirus disease 2019 (COVID-19) disease by describing the morbidity and mortality as well as the length of postoperative hospital stay.

The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.
