  Purpose

This project is designed to address the following hypothesis:

Distinct patterns in lung microbiome are characteristic of sarcoidosis phenotypes and reflected in changes in systemic inflammatory responses as measured by peripheral changes in gene transcription.

The Specific Aims are:

  1. To identify peripheral blood mononuclear cell (PBMC) gene expression patterns that characterize distinct sarcoidosis phenotypes.
  2. To determine whether patterns in the lung microbiome are associated with sarcoidosis severity and disease phenotypes
  3. To correlate mRNA and microRNA expression patterns in sarcoidosis affected organs with changes in microbiome, clinical parameters and PBMC gene expression patterns
  4. To integrate clinical, transcriptomic, and microbiome data to identify novel molecular phenotypes in sarcoidosis.

Primary Outcome Measures:
  • PBMC Gene Expression [ Time Frame: Baseline, 6 months, 12 months ] [ Designated as safety issue: No ]
    To identify peripheral blood mononuclear cell (PBMC) gene expression patterns that characterize distinct sarcoidosis phenotypes, samples will be run in batches in block designs (equal numbers of phenotypes) and batches will be analyzed independently to determine reproducibility - a subset of samples will be rerun to assure continuity and established normalization algorithms will be applied 1-3. Normalized human transcript (mRNA and microRNA) levels obtained from PBMC will be related to established phenotypes as well as cross phenotype characteristics using linear models, i.e., ANOVA or linear regression using the LIMMA package (http://bioinf.wehi.edu.au) or BRB ArrayTools (http://linus.nci.nih.gov/BRB-ArrayTools.html).

Detailed Description:

Sarcoidosis is a systemic disease characterized by the formation of granulomatous lesions, especially in the lungs, liver, skin, and lymph nodes, with a heterogeneous set of clinical manifestations and a variable course 1. Despite significant progress in the understanding of the genetic predisposition and role of immunity, it is still a challenge to explain the clinical presentation of sarcoidosis. Standard clinical assessment, imaging, and pulmonary function tests (PFTs) do not allow prediction of disease course and response to therapy. Furthermore, there are no good long-term therapies. Considering that the interactions between potential infections, changes in systemic inflammation, and patterns in lung microbiome and the different and distinct disease phenotypes in sarcoidosis are not well understood, the Sarcoidosis protocol for the Genomic Research in AAT Deficiency and Sarcoidosis (GRADS) grant (hereafter called GRADS Sarcoidosis protocol) is designed to address the following:

Hypothesis

Distinct patterns in lung microbiome are characteristic of sarcoidosis phenotypes and reflected in changes in systemic inflammatory responses as measured by peripheral changes in gene transcription.

Specific Aims

  1. To identify peripheral blood mononuclear cell (PBMC) gene expression patterns that characterize distinct sarcoidosis phenotypes.
  2. To determine whether patterns in the lung microbiome are associated with sarcoidosis severity and disease phenotypes
  3. To correlate mRNA and microRNA expression patterns in sarcoidosis affected organs with changes in microbiome, clinical parameters and PBMC gene expression patterns
  4. To integrate clinical, transcriptomic, and microbiome data to identify novel molecular phenotypes in sarcoidosis.

Focusing on accessible PBMCs should enable GRADS researchers to identify markers for disease phenotypes, severity, and outcome. Analysis of lesional transcriptomes (mRNA, microRNA and lincRNA) will add mechanistic insights. High throughput unbiased analysis of the lung microbiome will potentially identify patterns in the lung microbiome that determine disease activity and persistence, as well as response to therapy.

Participants are assigned a provisional clinical phenotype upon obtaining consent at time of enrollment by the respective recruiting center. Clinical phenotypes will be reviewed, confirmed, and monitored to ensure achievement of study objectives. Participants who cannot be assigned a clinical phenotype after the initial study visit will be excluded from additional study participation.

  Eligibility

Ages Eligible for Study:   18 Years to 85 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Subjects will be prescreened for predefined clinical phenotypes of sarcoidosis. Those who meet initial criteria and ERS/ATS criteria for a sarcoidosis diagnosis will be recruited and phenotyped by questionnaire, physical exam, research chest CT exam, pulmonary function tests, and blood and urine tests with a total recruitment goal of 400.

A subset of participants who have suspected pulmonary sarcoidosis, but who have not undergone a biopsy, will be recruited so that material may be obtained during their clinically indicated biopsy. If a diagnosis of sarcoidosis is confirmed, they will be enrolled and followed. If an alternative diagnosis is made, they will not undergo any further testing.

Participants who cannot be classified within the clinical phenotypes based on data from the initial visit will not continue in the study. Recruitment of participants with defined clinical phenotypes will be monitored and ongoing recruitment goals adjusted to achieve overall study objectives.

Criteria

Inclusion Criteria:

  1. Age between the ages of 18 and 85.
  2. Have a diagnosis of sarcoidosis established by consensus criteria (ATS/ERS), confirmed by either biopsy or by manifestations consistent with acute sarcoidosis (Löfgren's syndrome) in absence of other known diagnosis.

    OR Have a suspected diagnosis of sarcoidosis and is scheduled to undergo a biopsy procedure to confirm a diagnosis of sarcoidosis using the same consensus criteria (ATS/ERS).

  3. Able to tolerate and willing to undergo study procedures.
  4. Be capable of understanding study forms.
  5. Provide signed informed consent.

Exclusion Criteria:

  1. History of comorbid condition severe enough to significantly increase risks based on investigator discretion.
  2. Currently an active smoker.
  3. Undergoing bronchoscopy (clinical or research) with any one of the following:

    1. severe pulmonary impairment (<50% predicted FVC, <1 L FEV1; DLco <40% predicted, resting hypoxemia <92% with or without supplemental oxygen)
    2. other co-morbid disease that would preclude bronchoscopy.
