Measure
Low Dose Naltrexone (LDN)
Following a two-week baseline the study drug was administered daily for 8 weeks. Participants were informed that placebo or LDN would be provided during the drug period and that all participants would receive LDN at some point during the study. In fact, all participants received the active LDN (4.5 mg nocte) throughout the drug-administration period. Low Dose Naltrexone: Naltrexone 4.5 mg p.o. nocte

Low Dose Naltrexone (LDN)
n=8 Participants
Following a two-week baseline the study drug was administered daily for 8 weeks. Participants were informed that placebo or LDN would be provided during the drug period and that all participants would receive LDN at some point during the study. In fact, all participants received the active LDN (4.5 mg nocte) throughout the drug-administration period. Low Dose Naltrexone: Naltrexone 4.5 mg p.o. nocte
Change in IL-22 From Baseline.

PRIMARY outcome

Timeframe: Baseline period (2 weeks) through end of drug phase (8 weeks) [10 weeks total].

Visual analog scale (0-100) anchored at "no pain" at 0 and "worst possible pain" at 100. Improvement in pain would be indicated by a decrease in the score.
