About this trial

This study plans to learn more about people who are sick in the hospital with a lung infection, or respiratory failure. Respiratory failure, or severe lung failure, is a life-threatening disease. When it happens, the lungs have trouble carrying out their normal function of getting oxygen into the blood, and removing carbon dioxide from the body. Investigators are conducting this study to see what drinking too much alcohol, using tobacco products, or using drugs (both legal and illegal) may do to lung infections and respiratory failure.

Subjects are asked to be in this research study because they are thought to have a lung infection and may also have respiratory failure. Alcohol, tobacco, and drug use have been linked to lung infections, respiratory failure, and even death, but the reasons for this aren't known. People who use unhealthy amounts of alcohol, tobacco, and or drugs may be more at risk for lung infections, and for severe complications due to lung infection. Subject participation is important whether or not you use alcohol and or drugs.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Specific Aim 1: Adult medical ICU patients admitted to the University of Colorado Hospital for a primary respiratory problem, and who are expected to require ICU care ≥48 hrs

Specific Aim 2: (1) Adult medical ICU patients with respiratory failure (due to underlying lung pathology) and who require endotracheal intubation and mechanical ventilation. (2) Adult medical and other ICU patients with respiratory failure, not related to a lung condition, and who require endotracheal intubation and mechanical ventilation. (3) Adult ICU patients previously admitted to the University of Colorado Hospital for a primary respiratory problem, and who required care ≥48 hrs.

Disqualifiers

Patients who are expected to require ICU care <48 hrs

Patients admitted to the ICU who are not ICU status (being housed for space issues)

Patient is unlikely to survive 48 hours

Patient is on comfort care (hospice measures)

Trial population

Specific Aim 1. Adult medical ICU patients admitted to the University of Colorado Hospital for a primary respiratory problem, and who are expected to require ICU care ≥48 hrs Specific Aim 2. Adult medical ICU patients with respiratory failure (due to underlying lung pathology) and who require endotracheal intubation and mechanical ventilation

Time perspective

Prospective

Treatments tested in this trial

  • Characterize alcohol and drug use

    Other intervention

    Characterize alcohol and drug use in patients newly admitted to the medical ICU service, who are expected to stay in the ICU for greater than 48 hours. The investigators will collect blood, exhaled breath condensate, urine and hair samples over the first 10 days of hospitalization. A select subset of subjects will have bronchoalveolar lavage (BAL) obtained.

Treatment groups

300 Participants
are divided into 2 treatment groups
Group A: Adult ICU patients with respiratory problem1 intervention
Group B: Intubated Adult ICU patients with respiratory failure1 intervention

Trial outcomes

Primary outcomes

1

Prevalence of alcohol use disorders (AUDs)

Among medical ICU (MICU) patients who remain in ICU greater than or equal to 48 hours: Prevalence of alcohol use disorders (AUDs), drug use disorders (DUDs), their combination (both), or no AUD/DUDs. Absolute value, and change over 7 days, in serum/urine/exhaled breath condensate/hair cortisol, corticotropin releasing hormone (CRH), adenovirus proteinase (AVP), and adrenocorticotropic hormone (ACTH), stratified by AUD/DUD/both/neither. 3 Month and 6 Month follow up were added to this outcome measure via a protocol amendment after study-start.

Time frame
prevalence, absolute value and change over 7 days, 3 Month follow up, 6 Month follow up
2

Incidence and etiology of respiratory failure, stratified by AUD/DUD/both/neither

Among medical ICU (MICU) patients who develop respiratory failure: Incidence and etiology of respiratory failure, stratified by AUD/DUD/both/neither. Length of time on mechanical ventilation stratified by AUD/DUD/both/neither. Inflammatory profile of BAL stratified by AUD/DUD/both/neither: BAL cell count and differential, Pro-inflammatory BAL cytokines; CCL5, TNFa, interferon-gamma (IFNg), interleukin (IL-1b), interleukin (IL-6). Evidence of oxidative stress in BAL (GSH/glutathione disulfide (GSSG) ratio, pH). Alveolar macrophage activation, degree of apoptosis, and inflammatory cytokine production. Confirm in non-invasively collected samples. Development of Acute Respiratory Distress Syndrome (ARDS) stratified by AUD/DUD/both/neither; Berlin criteria, Lung injury score.

Time frame
participants will be followed for the duration of hospital stay, an expected average of 17 days
3

Incidence and etiology of respiratory failure, stratified by AUD/DUD/both/neither: Month 3

Among medical ICU (MICU) patients who develop respiratory failure: Incidence and etiology of respiratory failure, stratified by AUD/DUD/both/neither.
