NCT06414720

Brief Summary

This study aims to analyze the salivary miRNA specific for patients diagnosed with endometriosis, specifically evaluating the miRNA profile of patients who respond versus those who do not respond to progestin therapy. Ninety patients attending the Chronic Pelvic Pain Clinic will be recruited, and they will be asked to provide a saliva sample before starting medical therapy. The response to the therapy will be evaluated after 4 months from the beginning of the therapy itself.

Outcome Measures

Primary Outcomes (3)

  • response to the progestin therapy

    response to 2 mg dienogest therapy evaluated with NRS (numeric rating scale) scale assessed for acyclic pain, dyspareunia, dyschezia, dysmenorrhea, periovulatory pain

    0 (pre-therapy) - 4 months (after therapy)

  • changes in quality of life

    changes in quality of life assessed with questionnaire SF-36 (Short Form Health Survey 36)

    0 (pre-therapy) - 4 months (after therapy)

  • differences in salivary miRNoma

    Once it is established which patients are responders and which are non-responders, differential salivary miRNAs between the two groups will be identified via sequencing. The miRNA reverse transcription reaction will be performed using the reverse transcription kit TaqMan MicroRNA (Applied Biosystems). The reverse transcription product will be used for Real-time PCR. The small nucleolar RNA RNU6 will be used as an endogenous control. The protocol of Amplification will be carried out using the LightCycler 480 instrument (Roche). For each miRNA, qPCR will be performed in duplicate. The relative expression levels of miRNAs will be calculated using the 2-ΔΔCt method.
