Glutathione and Health With Post-Polio Syndrome

Not Applicable

Completed

• Conditions: Post-polio Syndrome; Depression; Sleep Disorders; Physical Activity; Pain
• Interventions: Dietary Supplement: Glutathione

• Registration Number: NCT01402570
• Lead Sponsor: University of Michigan

Brief Summary

In this study, people who have symptoms of post polio will take oral glutathione supplements for three months. Their levels of fatigue, physical activity and sleep efficiency will be assessed.

Detailed Description

Subjects will take a glutathione supplement by mouth for three months after an initial medical visit, blood draw and physical exam. There are four timepoints during the three months when subjects will fill out surveys and record food intake and sleep times in diaries for seven days. They will also wear a small device for seven days, a Sensewear monitor that records physical activity, body temperature and other measures.

After the fourth timepoint they will return to the medical center for another physical exam and blood draw. Physicians trained in physical medicine and rehabilitation will be monitoring the study.

Arm && Interventions

Group	Intervention	Description
Glutathione supplement	Glutathione	All subjects will be taking a glutathione supplement.Glutathione is a naturally occuring antioxidant and a nonessential amino acid.

Primary Outcome Measures

Name	Time	Method
Sleep Efficiency	Baseline, 1 month, 2 months and 3 months	The ratio of time asleep over time in bed gathered from sleep diaries completed at bedtime and at awakening. Scores range from 0 to 100%, higher values indicate better sleep efficiency or more time sleeping in bed.
PROMIS (Patient Reported Outcomes Measurement Information System) Fatigue	Baseline, 1 month, 2 months and 3 months	Assesses fatigue from mild subjective feelings to an overwhelming, debilitating, and sustained sense of exhaustion that is likely to decrease one's ability to carry out daily activities, including the ability to work effectively and to function at one's usual level in family or social roles. Fatigue is divided conceptually into the experience of fatigue (e.g., frequency, duration, and intensity), and the impact of fatigue upon physical, mental and social activities. Scores are on a T-metric with mean of 50 and standard deviation of 10; higher scores indicate greater fatigue.
Steps Per Day	Baseline, 1 month, 2 months and 3 months	Count of steps per day using activity monitor worn on upper arm.
PROMIS (Patient Reported Outcomes Measurement Information System) Physical Functioning	Baseline, 1 month, 2 months and 3 months	Ability to carry out activities that require physical actions, ranging from self-care (activities of daily living) to more complex activities that require a combination of skills, often within a social context. Scores are standardized T-scores with mean of 50 and standard deviation of 10; higher scores indicate better physical function.
