简要总结

Endometriosis (EMs) is one of the most prevalent benign gynaecological diseases, and it is an inflammatory oestrogen-dependent condition. Several authors have proposed that anatomical, genetic, endocrine, immunological, environmental, hormonal, and inflammatory factors may influence tissue implantation outside the uterus. An approach to EMs aetiology that involves defining a profile to the vaginal and gut microbiota, estrogenic activity, and exposure to xenoestrogens and also metabolic and nutritional status of women with EMs may help identify some important patterns to better characterize this disease and also to define more personalized nutritional strategies, also predicting patients' predisposition to therapy success. This is an observational study on premenopausal woman, diagnosed with EMs, who will be recruited on the outpatient gynaecology appointment, to evaluate the vaginal and intestinal microbiome, measure the total estrogenic activity, assess the metabolic biomarkers and the nutritional status.

结局指标

主要结局

Omega-3 index

时间窗: day 1

Mean/median of omega-3 index (uL) levels at baseline.

Alpha (α)-tocopherol

时间窗: day 1

Mean/median of α-tocopherol (ug/mL) levels at baseline.

Vaginal microbiome

时间窗: day 1

Characterization of the vaginal microbiome. Bacterial DNA will be extracted from cytology samples. 16S rRNA gene will be sequenced by next-generation sequencing (NGS). All the identified bacterial phyla, genus and species will be expressed in percentage.

Strogen levels

时间窗: day 1

Mean/median of total and free estrone (E1) and estradiol (E2) (ng E2-equivalents L-1) at baseline.

Total cholesterol

时间窗: day 1

Mean/median of total cholesterol (mg/dL) levels at baseline.

25-hydroxy vitamin D

时间窗: day 1

Mean/median of 25-hydroxy vitamin D (ng/mL) levels at baseline.

Intestinal microbiome

时间窗: day 1

Characterization of the intestinal microbiome at baseline. Bacterial DNA will be extracted from fecal samples. 16S rRNA gene will be sequenced by next-generation sequencing (NGS). All the identified bacterial phyla, genus and species will be expressed in percentage.

Insulin

时间窗: day 1

Mean/median of insulin (μU/mL) levels at baseline.

LDL cholesterol

时间窗: day 1

Mean/median of low-density lipoprotein (LDL) cholesterol (mg/dL) levels at baseline.

Fasting blood glucose

时间窗: day 1

Mean/median of fasting blood glucose levels (mg/dL) levels at baseline.

HDL cholesterol

时间窗: day 1

Mean/median of high-density lipoprotein (HDL) cholesterol (mg/dL) levels at baseline.

Ascorbic acid

时间窗: day 1

Mean/median of ascorbic acid (umol/L) levels at baseline.

次要结局

  • Quality of life questionnaire(day 1)
  • Symptoms severity(day 1)
