Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To characterize a population of tension-type headache patients by means of phenotyping and genotyping into different groups that would facilitate the selection of adequate treatment for each individual patient.;Secondary Objective: 1 - To assess if the response to treatment with mirtazapine of TTH patients can be predicted by conditioned pain modulation. 2- To investigate the expression of NO, TNF-a, IL-1ß, IL-6 and ß2- and ß3-adrenergic receptors in nerve fibers of muscles of Tension-type headache patients and controls.;Primary end point(s): The primary efficacy variables are number of headache days, severity of headache (on a 0-10 scale attack where where "0" is no pain/discomfort and "10" is the worst pain/discomfort) and amount of rescue medication taken.;Timepoint(s) of evaluation of this end point: At baseline, 1 month after baseline and 2 months after baseline. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The secondary variables are a modified total tenderness score (TTS) (0 to 100 scale with 0 being "no sensation whatsoever", 1 to 49 being "sensation of pressure but the stimulus is not painful", 50 being "barely painful" and 100 being "the most painful imaginable"), Quantitative sensory testing scores (QST), changes in PPTs during the conditioned pain modulation (CPM) paradigm, amount of expression of NO, TNF-a, IL-1ß, IL-6 and ß2- and ß3-adrenergic receptors in nerve fibers of the assessed muscles and autonomic nervous system (ANS) variables such as heart rate variability.;Timepoint(s) of evaluation of this end point: TTS, QST, CPM and ANS parameters will be assessed at baseline, 1 month after baseline and 2 months after baseline. Assessment of expression of NO, TNF-a, IL-1ß, IL-6 and ß2- and ß3- adrenergic receptors in nerve fibers of the assessed muscles will be done at baseline and 2 months after baseline. | — |
