Brief summary

Pilot study into low dose naltrexone (LDN) and NAD+ for treatment of patients with post-COVID-19 syndrome.

Detailed description

This interventional pilot study will assess the use of low dose naltrexone (LDN) and NAD+ for the treatment of patients with post-COVID-19 syndrome (long-COVID-19). Patients with a positive test for SARS-CoV-2 1-4 months before enrollment will be included. Subjects should have self diagnosed post-COVID19 syndrome and experiencing persistent fatigue since positive test. Patients will be screened using the fatigue survey and cases with a moderate to severe score will be included. Patients will receive LDN and NAD+ treatment for 12 weeks. In this study, fatigue and quality of life will be assessed using validated surveys. Surveys will be conducted at baseline (at the time of enrollments, before treatment), and at 2, 4, 8, and 12 weeks. The improvement of scores from baseline levels will be assessed.

Interventions

DRUGNaltrexone

Naltrexone at 4.5 mg/day

DIETARY_SUPPLEMENTNAD+

NAD+ will be applied using iontophoresis patches. The patches will be provided by ready-made NAD+ solutions (400 mg) to be applied to the positive electrode of the patch and saline to the negative electrode. The patch is powered by a self-contained battery, producing an electric current to facilitate NAD+ absorption through the skin into the blood. Patches are worn for 4-6 hours once a week.

Intervention model description

Patients will receive LDN and NAD+ treatment for 12 weeks. The researchers will assess fatigue and quality of life using validated surveys. Surveys will be conducted at baseline (at time of enrollments, before treatment), and at 2, 4, 8, and 12 weeks. Improvement of scores from baseline levels will be determined.

Design outcomes

Primary

MeasureTime frameDescription
Reduction of fatigue in post-COVID-19 syndrome by treatment with LDN and NAD+12 weeksReduction of fatigue score from baseline as measured by the Chalder fatigue scale in post-COVID-19 syndrome by treatment with LDN and NAD+. The Chalder scale has a minimum value of 0 and a maximum value of 33, and the higher the score the more severe the fatigue symptoms are.

Secondary

MeasureTime frameDescription
Improvement of quality of life in post-COVID-19 syndrome by treatment with LDN and NAD+.12 weeksImprovement of quality of life scores from baseline as measured by the short form-36 (SF-36) survey in post-COVID-19 syndrome by treatment with LDN and NAD+. The SF-36 survey provides scores between 0-100 with lower scores representing more disability.
