Ketonemia Through Menstrual Cycle

An observational study in Epilepsy, Drug Resistant Epilepsy and GLUT1DS1, sponsored by University of Pavia. Recruiting at 1 site in Italy. Open to female participants aged 12 Years to 35 Years. Per ClinicalTrials.gov, last updated 2023-05-11.

Why
  1. The study's listed conditions name Drug Resistant Epilepsy, a narrower term within Epilepsy.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

Ketogenic dietary therapies (KDTs) are well-established, safe, non-pharmacologic treatments used for children and adults with drug-resistant epilepsy and other neurological disorders. Ketone bodies levels undergo a significant inter-individual and intra-individual variability and can be affected by several factors. This evidence suggests the need for personalized monitoring for diet optimization, especially at the beginning of the treatment but during whole follow-up. Possible variations in glycemia and ketone bodies' blood level according to different phases of menstrual cycle have not been systematically assessed yet, but this time window deserves special attention because of hormonal and metabolic related changes. We present the methodological protocol for a longitudinal, multicentric study aimed at searching for subtle changes in ketone bodies blood level during menstrual cycle in epileptic female patients undergoing a stable ketogenic diet. The study will be divided into two phases. The first one will be purely observational, aiming at the assessment of ketonemia during menstrual cycle. Whether this finding will be confirmed, a second phase of ketogenic diet therapy adjustment will be scheduled.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 11, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
