Trial summary

Despite the availability of highly active antiretroviral therapy (HAART), lung diseases remain a leading cause of morbidity and mortality in those with HIV infection. There have been no large-scale studies detailing pulmonary complications in the HAART era. Read more about this study

Who cannot join

  • Subject is experiencing acute onset of shortness of breath, cough, fevers or heart conditions problems such as tachycardia, angina or arrhythmias.
  • Female subject has told us she is pregnant (this might affect pulmonary function values,we will not require pregnancy testing.)

About this study

Despite the availability of highly active antiretroviral therapy (HAART), lung diseases remain a leading cause of morbidity and mortality in those with HIV infection. There have been no large-scale studies detailing pulmonary complications in the HAART era. Substantial gaps exist in our knowledge of the spectrum and pathogenesis of pulmonary disorders in this population, particularly in women and minorities whose numbers with HIV or AIDS have increased. The Multicenter AIDS Cohort Study (MACS) and the Women's Interagency Health Study (WIHS) are prospective, multi-center cohorts that follow approximately 5000 HIV+ subjects and HIV- controls. Although pulmonary disease has not been an area of focus, these established cohorts provide a unique opportunity to systematically study pulmonary complications of HIV infection.

Emphysema is of particular interest in the current HIV era because it is likely to increase as this population lives longer with chronic HIV. HIV-infected persons have an increased incidence of emphysema compared to those without HIV infection, and it has been hypothesized that this accelerated disease progression is the result of one or more latent infectious agents that amplify the pulmonary inflammation. Accelerated emphysema was described in HIV infection in a predominantly male population before HAART. The current prevalence and characteristics of HIV-associated emphysema, and the potential impact of gender, have not been rigorously defined.

Read the detailed description

HIV-infected patients have an increased incidence of emphysema compared to non-HIV-infected patients, and it has been hypothesized that this accelerated disease progression is the result of one or more latent infections that amplifies the pulmonary inflammatory response. We will examine the prevalence and progression of emphysema in subjects with and without HIV and determine risk factors for emphysema in this population.

Subjects will be 300 HIV+ subjects and 300 HIV- controls selected by random sampling stratified by age and smoking history. Subjects will be recruited from the University of Pittsburgh and the University of California Los Angles (UCLA) MACS sites. The University of California San Francisco (UCSF) will serve as the recruiting center for the WIHS cohort. Because we are interested in an unbiased estimate of the extent of this disease in HIV infection, we will not select subjects based on lung function or current diagnosis of COPD. The HIV- subjects will be matched to the HIV+ subjects in terms of age and smoking history to the extent possible. Those with symptoms of acute respiratory disease such as fevers, acute change in cough or shortness of breath, or weight loss will be excluded. There will be no exclusions based on HAART use or opportunistic infection (OI) prophylaxis and no exclusions based on previous lung disease as we are trying to obtain a comprehensive evaluation of emphysema in this population as well as identify associated risk factors.

All subjects will undergo spirometry, diffusing capacity and quantitative CT scanning. These measurements will allow us to determine differences in the prevalence of emphysema in HIV+ and HIV- and determine risk factors associated with emphysema. For longitudinal studies testing the hypothesis that emphysema is accelerated in HIV infection, we will select HIV+ and HIV- subjects with documented emphysema in each group as defined by diffusing capacity<80% predicted, post-bronchodilator FEV1/FVC<70% without significant reversibility, or at least 10% of lung with a density less than -910 Hounsfield units (HU). These subjects will have CT scans and PFTs at baseline and at 18 months and 36 months after baseline. At each visit, clinical data and biological samples will be collected.

1Subjects will be 300 HIV+ subjects and 300 HIV- controls selected by random sampling stratified by age and smoking history. Subjects will be recruited from the University of Pittsburgh and the University of Washington (UW) MACS sites.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The overall objective of the Pitt coordinating center is to build a collaborative collection of data and specimens that will facilitate the study and understanding of HIV and pulmonary disease

    This prospective, multicenter cohort study will survey HIV-infected and non-infected individuals and test for airway obstruction and emphysema and determine associated risk factors. Subjects may be invited back for repeat testing at 18 and 36 months based on the initial test results and measures. Subjects at the multicenter sites may participate in this study for approximately 36 months. Each individual site (University of Pittsburgh, UCLA, UCSF) will be a descriptive longitudinal study to examine the prevalence and progression of emphysema in HIV+ and HIV-subjects.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of HIV Infections and Emphysema, run by University of Pittsburgh at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The overall objective of the Pitt coordinating center is to build a collaborative collection of data and specimens that will facilitate the study and understanding of HIV and pulmonary disease (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00870857, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2025.
