Patients over 18 years of age presenting with hemoptysis at the Centre Hospitalier Universitaire de Sherbrooke (CHUS) between the periods of 2005 to 2010.

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.

RATIONALE:

Hemoptysis, mild or massive, is worrisome for both patients and physicians. The management is different depending on the causes, which are not well defined for the North American population. Despite the fact that this symptom is commonly reported in clinic, there are only a few studies published on this subject in the North-American population. Tuberculosis was a frequent cause of hemoptysis described in populations overseas, which seems less prevalent in the investigators center.

Also, there are no known official guidelines regarding the investigation and management of hemoptysis. The investigators hypothesized that the use of modern technology in a North American population may result in different findings and provide a more accurate diagnostic approach.

Therefore, the study compares the different etiologies of hemoptysis and investigation modalities used in patients presenting in a North-American tertiary center.

METHOD:

The investigators did a retrospective analysis of medical chart from patients with hemoptysis who visited the investigators center between 2005 and 2010. Each visit has been reviewed individually to describe the characteristics of patients, etiologies of hemoptysis and investigation modalities used. All-cause mortality at 2 years was also recorded.

Descriptive statistical analyses will conducted on the data available.

Etiologies, Investigations and Outcomes of Patients Presenting With Hemoptysis

Etiologies, Investigations and Outcomes of Patients Presenting With Hemoptysis in a North-American Tertiary Center at the Beginning of the 21st Century

Defining the prevalence of pulmonary diseases by measuring the percentage of patients presenting with hemoptysis caused by lung cancer, bronchiectasis, pulmonary embolism, arteriovenous fistula, pneumonia, bronchitis, tuberculosis, mycosis, heart failure, pseudohemoptysis, cryptogenic and other causes.

Determining the sensitivity in obtaining the etiology of the hemoptysis episode of each diagnostic modality that follows : chest X-ray, chest CT-scan and CT-angiography, bronchoscopy, ventilation-perfusion with single-photon emission computed tomography and pulmonary angiography in the diagnosis of different etiologies of hemoptysis.

All-cause mortality at 2 years after the diagnosis of hemoptysis.

Determining the percentage of patients who : never smoked, is an active smoker, former smoker or unknown status.

Determining the average age of the enrolled patients.

Determining the percentage of each gender of the enrolled patients.

Determining the median of the international normalized ratio (INR).

Determining the median of the partial thromboplastin time (PTT).

Determining the average of the platelet count measured per microliter of blood.

Nisha Rathi, MD

This is a drug study that will examine if inhaled tranexamic acid can improve mortality in patients with cancer-related pulmonary hemorrhage and respiratory failure as compared to usual care.

Primary Objective: To assess the benefit of using nebulized tranexamic acid versus the standard of care on 30 day mortality.

Secondary Objectives: To assess the following outcomes when using nebulized tranexamic acid versus the standard of care:

1. 100 day, ICU and hospital mortality rate
2. Ventilator days at day 30
3. ICU and Hospital Length of Stay
4. PaO2:FIO2 ratio (or SpO2:FIO2 ratio) changes over the first 14 days
5. Time to resolution of pulmonary hemorrhage
6. Rate of recurrence of pulmonary hemorrhage
7. Rate of invasive procedures required to control pulmonary hemorrhage

A Randomized Controlled Trial of Inhaled Tranexamic Acid for the Treatment of Pulmonary Hemorrhage in Cancer Patients

Number of patients who are alive at 28 days following randomization. The difference between 28-day mortality rates between treatment arms will be computed along with a 95% confidence interval (CI) using the approximate standard error reported in Fleiss (1981). Logistic regression will be used to estimate the association between 28-day mortality and study covariates of interest.
