Acute PainNCT01524523
Bone Marrow Aspiration Pain Study
An observational study of Acute Pain and Gene Expression, run by National Institutes of Health Clinical Center (CC).
Trial summary
Background: Many people feel pain during and after bone marrow aspiration (collection). Studies suggest that pain may be related to different kinds of inflammation, or the presence of nitric oxide (a normally occurring gas) in the body. Read more about this study

About this study
Official title: Biochemical and Genetic Mechanisms of Acute Clinical Pain During Bone Marrow Aspiration
Background:
- Many people feel pain during and after bone marrow aspiration (collection). Studies suggest that pain may be related to different kinds of inflammation, or the presence of nitric oxide (a normally occurring gas) in the body. Researchers want to study nitric oxide levels in the blood and breath before and after bone marrow collection. They will look at how these levels relate to feelings of pain.

Objectives:
- To better understand pain related to having a bone marrow collection.
Eligibility:
- Individuals at least 18 years of age who are enrolled in a study that requires bone marrow collection.
Design:
- Participants will be screened with a physical exam, medical history, and blood sample.
- Participants will provide study blood and breath samples to check nitric oxide levels. Participants will also have a test to measure skin sensitivity to heat and touch.
- During the collection, participants will keep track of their pain levels.
- After the collection, participants will keep track of any pain medications they take. They will also record if and when they eat any foods that contain nitrates for about 24 hours.
Read the detailed description
Abstract:
This project will explore the biochemical mechanisms associated with acute pain produced by bone marrow aspiration in 36 healthy subjects by : 1) Evaluation of any strong relationships of NO metabolism (as measured by plasma nitrite, nitrosated proteins, cyclic GMP, plasma hemoglobin, reticulocytes, as well as markers of inflammation) with the levels of acute pain in healthy subjects and; 2) Identification of differentially expressed genes and proteins as markers for the nature and severity of pain from bone marrow aspiration. Elucidation of these relationships may identify novel targets for intervention leading to attenuation of pain, improved treatment and less impact on quality of life (QOL) and may identify potential mechanisms for the role of NO in other inflammatory or pain syndromes.
Objectives:
The first objective of the study is to characterize genetic expression during acute pain and pain free phases pre and post bone marrow aspiration (BMA). The second objective is to measure at multiple time points levels of exhaled Nitric Oxide (eNO) and other biomarkers in subjects during pre- and post BMA. The third objective is to evaluate acute and experimental pain perception in these subjects.
Population:
This study will recruit healthy subjects (N=36) who have agreed to donate bone marrow.
Design:
This is a prospective, exploratory study of sensory and affective pain in healthy volunteers. Participants will undergo evaluations (eNO, blood collection, and quantitative sensory testing) during a clinic visit to undergo bone marrow aspiration.
Importance:
The purpose of this study is to improve the understanding of the biochemical and molecular genetic mechanisms associated with acute pain in a healthy population by characterizing the leukocyte transcriptome of pain pre- and post BMA. It is hypothesized that analysis of the transcriptome will result in a panel of biomarkers that correlate with acute pain in a healthy population. The successful elucidation of these relationships may identify novel targets for intervention leading to attenuation of pain, improved treatment and less impact on quality of life and functional status.

Questions about this trial
What is this clinical trial studying?
An observational study of Acute Pain and Gene Expression, run by National Institutes of Health Clinical Center (CC).
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 4 inclusion and 10 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: withdrawn, as of the sponsor's last update on 2 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.
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 was withdrawn before enrolling participants, so there are no results.
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?
Differences over time between whole blood gene expression in the peripheral blood of healthy subjects undergoing an acute pain stimulus.. 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 NCT01524523, which also lists 3 linked publications.
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 2 Jul 2017.
