Oxidative Stress and Inflammatory Biomarkers in Gaucher Disease
January 28, 2024 updated by: University of Minnesota
Novel Inflammatory Biomarkers Complement 5A and Hepcidin in Patients With Gaucher Disease (GD)
The objective of this study is to evaluate oxidative stress and/or inflammation in patients with Gaucher disease type I using a series of biomarkers and correlate with measurements of currently used diagnostic biomarkers.

Conditions
Detailed Description
We will determine oxidative stress and/or inflammation related biomarkers in whole blood and/or plasma in adult subjects with Gaucher disease.
Fifteen milliliter blood sample will be collected during three independent visits over a period of approximately 3 months.
These samples will be processed to separate plasma from red blood cells and frozen until assays are performed.
Standardized immunoassay methods and LC/MS based methods will be adopted to assay a series of biomarkers in these samples.
These data will be correlated with currently used diagnostic biomarkers.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
18 years to 75 years (Adult, Older Adult)
Accepts Healthy Volunteers
No
Sampling Method
Non-Probability Sample
Study Population
Type 1 Gaucher disease subjects who are either naive to treatment or are stable on therapy (specific Enzyme Replacement Therapy (ERT) / Substrate Reduction Therapy (SRT) formulation at a specific dose) for at least 2 years.
Description
Inclusion criteria:
- All participants must be 18 years or older.
- All enrollees must understand and cooperate with requirements of the study in the opinion of the investigators and must be able to provide written informed consent.
- Individuals with Gaucher disease who are medically stable for participation in study in the opinion of the investigator.
- GD subjects must be stable on a specific ERT and/or SRT therapy at a specific dose (for e.g. on a units/kg basis) for at least 2 years or be naïve to these therapies (no therapy for 2 years).
- GD1 patients, who have had a change in therapy i.e. a change in dose or switch from one drug to another, can be enrolled after at least 6 months have elapsed since the change and is considered stable in the opinion of the clinician providing care to the patient.
- All participants must not have taken antioxidants coenzyme Q-10, vitamin C, or vitamin E for 3 weeks prior to the study.
Exclusion Criteria:
- Medically unstable conditions in any group as determined by the investigators
- Concurrent disease; medical condition; or an extenuating circumstance that, in the opinion of the investigator, might compromise subject safety, study compliance, completion of the study, or the integrity of the data collected for the study.
- Females who are pregnant or lactating or of child-bearing age who are not using acceptable forms of contraception
- History of asthma that is presently being treated
- Subjects who cannot or are unwilling to have blood drawn
- Unable to adhere to study protocol for whatever reason
