Evaluation of Nutritional Status, Eating Habits and Improvement of Symptoms With a Nutritional Intervention in Women With enDometriosis

Study Overview
=================
Brief Summary
-----------------
The study aims to investigate the nutritional status and eating habits of women suffering from endometriosis and chronic pelvic pain in relation to describe the possible improvement of clinical symptoms following a nutritional intervention. The primary aim is to describe and evaluate the impact of nutritional intervention on clinical symptoms (pain, quality of life and intestinal function) in women suffering from endometriosis with chronic pelvic pain. The first secondary aim will be to describe and evaluate the impact of the nutritional intervention by describing the changes in some specific areas of the patients (sexual, psychological) together with the quantification of some routine blood chemistry parameters (inflammatory markers, levels of proteins and vitamins) . The second secondary objective will be aimed at describing the changes in clinical symptoms and the parameters mentioned above in patients based on the severity/stage of the pathologies under study.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Observational group<br>A nutritional assessment will be held with the detection of anthropometric parameters. Each participant will be asked to fill in the SF36, the VAS scales, the KESS questionnaire, the SFFI questionnaire, the Questionnaire PUF and O'Leary/Santn, the BDI and the TAS for an assessment of the psychological component. In addition, patients will be asked to fill in a FFQ of food consumption and a 7 days food diary. Finally, routine blood chemistry tests will also be performed, to which will be added those for measuring the inflammatory state and stool examination for the evaluation of fecal Calprotectin for the measurement of intestinal inflammatory markers. The nutritional intervention will consist in providing general nutritional indications specific for endometriosis and an indicative daily diet plan, which must be followed for 6 months. At the end of the 6 months, all anthropometric assessments, blood chemistry and stool tests will be repeated, together with the questionnaires. | Other: Nutritional intervention<br>* The nutritional intervention will consist in providing general nutritional indications specific for endometriosis and an indicative ungrammatical daily diet plan, which must be followed for the entire period of intervention (6 months).<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The primary outcome is to describe and evaluate the impact of nutritional intervention on clinical symptoms (pain, quality of life and intestinal function) in women suffering from endometriosis with chronic pelvic pain. | The outcome will be assessed with repeated measurements using the following parameters: -Evaluation of chronic pelvic pain, dysmenorrhea, dyschezia and dysuria: VAS visual analogue scale, from 0 to 10 points where 10 points indicates worst pain | 6 months | 
| The primary outcome is to describe and evaluate the impact of nutritional intervention on clinical symptoms (quality of life) in women suffering from endometriosis with chronic pelvic pain. | The outcome will be assessed with repeated measurements using the following parameters: Quality of life: measurement of physical and mental components with SF36 consisting of two components, one physical and one mental. Both fall within a range from 0 to 100 points where higher values are associated with better health | 6 months | 
| The primary outcome is to describe and evaluate the impact of nutritional intervention on clinical symptoms (intestinal function) in women suffering from endometriosis with chronic pelvic pain. | The outcome will be assessed with repeated measurements using the following parameters: Bowel Function: Knowles-Eccersley-Scott Symptom Questionnaire (KESS) (points) | 6 months |

| To describe and evaluate the impact of the nutritional intervention by describing the changes in Urinary function and bladder pain | The outcomes necessary to respond to the secondary objective are the administration of the following questionnaire: Urinary function and bladder pain: PUF and O's Leary / Sant questionnaire (points) | 6 months | 
| The secondary outcome will be to describe and evaluate the impact of the nutritional intervention by describing the changes in Psychological component about Depression | The outcomes necessary to respond to the secondary objective are the administration of the following questionnaire: Beck Depression Inventory (BDI) (points) | 6 months | 
| The secondary outcome will be to describe and evaluate the impact of the nutritional intervention by describing the changes in Psychological component | The outcomes necessary to respond to the secondary objective are the administration of the following questionnaires: Alexithymia Scale (TAS) questionnaire (points) | 6 months | 
| The secondary outcome will be to describe and evaluate the impact of the nutritional intervention by describing the changes in some routine blood chemistry parameters | The outcomes necessary to respond to the secondary objective are the administration of the following routine blood chemistry parameters: Measure Ca125 (unità/ml) and Vitamin D (ng/ml) | 6 months | 
| The secondary outcome will be to describe and evaluate the impact of the nutritional intervention by describing the changes in Intestinal inflammatory marker | The outcomes necessary to respond to the secondary objective are the administration of the following test: fecal calprotectin (mg/kg) | 6 months | 
| The secondary outcome will be to describe and evaluate the impact of the nutritional intervention by describing the changes in some Inflammatory markers | The outcomes necessary to respond to the secondary objective are the administration of the following Inflammatory markers: IL-6 and IL-1β values (pg/ml) | 6 months | 
| The secondary outcome will be to describe and evaluate the impact of the nutritional intervention by describing the changes in measurement of proteins | The outcomes necessary to respond to the secondary objective are the administration of the following measurement of proteins: C-reactive protein values (mg/dL) | 6 months |
