Abstract
A subset of patients experiences persistent fatigue symptoms after COVID-19, and patients may develop long COVID, which is characterized by lasting systemic symptoms.
No treatments for this condition have been validated and are urgently warranted.
In this pilot study, we assessed whether treatment with low-dose naltrexone (LDN, 4.5 mg/day) and supplementation with NAD + through iontophoresis patches could improve fatigue symptoms and quality of life in 36 patients with persistent moderate/severe fatigue after COVID-19.
We detected a significant increase from baseline in SF-36 survey scores after 12 weeks of treatment (mean total SF-36 score 36.5 [SD: 15.6] vs. 52.1 [24.8]; p < 0.0001), suggestive of improvement of quality of life.
Furthermore, participants scored significantly lower on the Chalder fatigue scale after 12 weeks of treatment (baseline: 25.9 [4.6], 12 weeks: 17.4 [9.7]; p < 0.0001).
We found a subset of 52 % of patients to be responders after 12 weeks of treatment.
Treatment was generally safe, with mild adverse events previously reported for LDN, which could be managed with dose adjustments.
The iontophoresis patches were associated with mild, short-lived skin irritation in 25 % of patients.
Our data suggest treatment with LDN and NAD+ is safe and may be beneficial in a subset of patients with persistent fatigue after COVID-19.
Larger randomized controlled trials will have to confirm our data and determine which patient subpopulations might benefit most from this strategy.
