Patient-reported Outcomes

Patients who completed both arms of the Wally et al. (2018) study were asked to answer an 8-question quality of life assessment following each 4-week treatment period and follow-up period.[8] Interestingly, although the study nurse did not note any significant change in pain and/or pruritis in the study subjects across time or between study groups, the question "Has your skin been itching recently, or have you had pain?" elicited a statistically significant difference between diacerein- and placebo-treated patients.[8] Thus, a positive effect of diacerein treatment, according to patients, was reduction in pain and pruritus of treatment areas, though this finding was not confirmed objectively. The other 7 quality of life assessments did not yield significance between diacerein and placebo; still, trends were generally similar and could perhaps become significant with increased power.[8]
