Role of Oxidative Stress and Inflammation in Type 1 Gaucher Disease (GD1): Potential Use of Antioxidant/Anti-inflammatory Medications


The purpose of this study is to measure levels of blood and brain chemicals related to oxidative stress and inflammation in healthy volunteers and individuals with Type 1 Gaucher disease (GD1) to see if these levels are altered by GD1. We will also examine if there is a change in these blood and brain chemicals after participants begin taking oral N-acetylcysteine (NAC), which is available both as a prescription medication and a natural product that has antioxidant and anti-inflammatory effects.

Inclusion Criteria:

• All participants must be 18 years or older.
• All participants 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 GD1 who are medically stable for participation in the study in the opinion of the investigator.
• GD1 patients must be on a stable, specific ERT and/or SRT therapy at a specific dose (e.g. on a units/kg basis) for at least 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.
• Healthy subjects who will be frequency-matched for age.
• All participants must not have taken antioxidants coenzyme Q-10, vitamin C, or vitamin E for 3 weeks prior to the study and during the course of 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.
• Women 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.
• Patients enrolled in another interventional study.
• Allergy to N-acetylcysteine.
• Patients who cannot or are unwilling to have blood drawn.
• Inability to undergo MRI scanning, including but not limited to: unable to remain still in an MRI scanner for more than 30 minutes, claustrophobia, presence of paramagnetic substances or pacemakers in body, weight over 300 lbs.
• Unable to adhere to study protocol for whatever reason.
