简要总结

Considering the high prevalence of DAO enzyme deficiency in patients referring insomnia symptoms, it would be plausible that the appearance of insomnia symptoms were explained by the DAO enzyme deficiency.

One of the strategies to revert DAO enzyme deficiency would be to supplement patients with DAO enzyme, helping at recovering the normal DAO levels. Therefore, the objective of the present study is to evaluate the effect of DAO enzyme supplementation on the insomnia symptoms characteristics in patients with insomnia symptoms and genetic DAO deficiency as expected from bearing at least one of the 4 above-mentioned SNPs of the AOC1 gene.

排除标准

  • Insomnia symptoms referred by patients that might be explained by other co-morbid sleep disorders, e.g., narcolepsy, circadian rhythm disturbances, parasomnia, etc.
  • Taking DAO supplementation less than 1 month prior to the start of the study.

结局指标

主要结局

Number (absolute and percentage) of patients who improve their symptoms of insomnia and daytime repercussions by at least one point in the Insomnia Severity Index (ISI) scale

时间窗: Visit day 0, day 7, day 14, day 21 and day 28.

Number (absolute and percentage) of patients who improve their symptoms of insomnia and daytime repercussions by at least one point in the Insomnia Severity Index (ISI) scale after one month of DAO supplementation, compared to the placebo group. Score goes from 0 to 28. A higher score indicates a worse outcome (severity of insomnia).

  • Number (absolute and percentage) of patients who improve their symptoms of insomnia and daytime repercussions by at least one point in the Pittsburgh Sleep Quality Index (PSQI) scale(Visit day 0 and day 28.)
  • Number (absolute and percentage) of patients who improve their symptoms of insomnia and daytime repercussions in the Pittsburgh Sleep Quality Index (PSQI) scale(Visit day 0 and day 28.)
  • Number (absolute and percentage) of patients who reduce at least one point on Component 2 (Sleep latency) of the Pittsburgh Sleep Quality Index (PSQI) scale(Visit day 0 and day 28.)
  • Number (absolute and percentage) of patients who reduce at least one point on Component 5 (Sleep disturbance) of the Pittsburgh Sleep Quality Index (PSQI) scale(Visit day 0 and day 28.)
  • Number (absolute and percentage) of patients who reduce at least one point on Component 7 (Daytime dysfunction) of the Pittsburgh Sleep Quality Index (PSQI) scale(Visit day 0 and day 28.)
  • Serum DAO activity levels(Visit day 0 and day 28.)
  • Number (absolute and percentage) of patients who increase their serum DAO activity levels(Visit day 0 and day 28.)
  • Mean DAO baseline activity levels(Visit day 0 and day 28.)
  • Mean increase in DAO activity levels(Visit day 0 and day 28.)
  • Number (absolute and percentage) of patients who improve their symptoms associated with histamine intolerance due to DAO deficiency(Visit day 0 and day 28.)
  • Number (absolute and percentage) of patients who refer improvement in their daytime repercussions of insomnia(Visit day 0, day 7, day 14, day 21 and day 28.)
  • Number (absolute and percentage) of patients in the once-a day groups who improve their symptoms of insomnia and daytime repercussions by at least one point in the Insomnia Severity Index (ISI) scale(Visit day 0, day 7, day 14, day 21 and day 28.)
  • Number (absolute and percentage) of patients in the three times per day groups who improve their symptoms of insomnia and daytime repercussions by at least one point in the Insomnia Severity Index (ISI) scale(Visit day 0, day 7, day 14, day 21 and day 28.)
  • Report of adverse events(Visit day 0, day 7, day 14, day 21 and day 28.)
