KETOMIGRAINE: Ketogenic Diet in Drug-resistant Chronic Migraineurs

KETOMIGRAINE: "Ketogenic Diet in Patients With Drug-resistant Chronic Migraine, "Non-responder" to Treatment With Monoclonal Antibody Targetting CGRP Pathway: a Pilot Study, Open Label"

Our protocol, named "KETOMIGRAINE", is based on the prescription of a Ketogenic Diet (KD) to twenty subjects with diagnosis of Chronic Migraine (CM), resistant to oral preventive treatments and non-responders to monoclonal antibodies targeting the CGRP pathway. The trial starts with one month of baseline during which are verified inclusion/exclusion criteria. After that, participants will assume KD for three months, a transitional diet (TD) for other three months. Follows a period of three months of free diet (FD). Neurological and dietician visits are scheduled during the course of the trial.

Detailed Description

The duration of the trial for individual participants is approximately 10 months, divided as follows: 1 month of baseline + 3 months of KD + 3 months of TD+ 3 months of follow-up.

The protocol includes 6 neurological evaluations (T0-T5); 11 dietary evaluations, some of which can be remote visits, and will be defined below with the acronym "V" (V1-V11).

The planned activities are listed below:

  • T0 screening: neurological and general physical examination, extended anamnestic evaluation, evaluation of the inclusion / exclusion criteria. Signature of the informed consent for participation in the research study, assignment of an identification code (increasing number starting from 01); headache diary delivery for prospective baseline data collection.
  • T1 baseline (30 days +/- 3 after T0): assessment of compliance in filling in the headache diary and confirming the diagnosis of chronic migraine; execution of electrocardiogram, pregnancy test (if female patient with childbearing potential) and blood tests (renal, hepatic, lipidic, endocrinological profile); first dietary visit (V1 - anthropometric measurements-BMI, interview on eating habits), nutritional instrumental evaluations (calorimetry and body composition).
  • T2 Day 1 (Enrollment -7 days +/- 3 after T1): verification of inclusion and exclusion criteria with the results of blood tests; blood sample for collection of PACAP, CGRP and metabolites of kynurenines; compilation of the disability and impact questionnaires - MIDAS and HIT-6; compilation of Migraine Specific Quality of Life Questionnaire (MSQ); dietary assessment (V2): prescription of the KD that the patient will follow for the next 3 months. Subjects overweight will follow a KD with a low-calorie content (low-calorie ketogenic diet); patients with a lower BMI will follow a normo-caloric diet: those represent the two subgroups of the study. Both subtypes of diet (normo and low-calorie) will induce at the same way ketosis; the only difference between the two subgroups is the fact that one will be associated with weight loss and the other not. During the three months of KD, dietician evaluations will be carried out every two weeks, alternating those remotely with those onsite (V3-V7). The dietary visits at the end of the 1st, 2nd and 3rd month of KD will be carried out onsite and the ketone dosage will be carried out using blood sticks.
  • T3 (3 months from T2 - end of KD and start of transitional diet - TD): evaluation of the headache diary and compilation of the disability and impact scales - MIDAS and HIT-6); repetition of blood tests in order to check dietary tolerance; blood sample for CGRP, PACAP, metabolites of kynurenines (II point); repetition of instrumental measurements (calorimetry and body composition); dietary visit (V8) for the last check of ketonemia and prescription of TD. This type of diet is not ketogenic and is characterized by the gradual introduction of carbohydrates starting from breakfast, it will last for 3 months. Onsite dietary visits (V9-V10) follow on a monthly basis
  • T4 (3 months after T3 - end of TD and start of free diet - FD): neurological and dietary visit (V 11) at the end of 3 months of TD. The patient will start a free diet, during which he/she can eat what is preferred.
  • T5 (3 months after T4 - end of study): The last visit is a follow-up, 9 months after T2, its purpose is to evaluate the trend of headache parameters, BMI and biochemical markers studied (III point). During this visit will be filled the following questionnaires: disability and impact questionnaires - MIDAS and HIT-6, Migraine Specific Quality of Life Questionnaire (MSQ), Patient's Global Impression of Change (PGIC).
