简要总结
This is a prospective, clinical, monocentric study aimed to collect biological samples and study microbiota from subjects suffering from subjects with recurrent cervicovaginitis, subjects with endometriosis, subjects with repeated implantation failures and from healthy volunteers. Microbiota is a complex consortium of microorganisms, located at the mucosal level (in particular intestinal, oral and vaginal) having a key role in human health and in the onset of several diseases. Microbiota alterations have been found in several diseases (gastrointestinal, metabolic, renal, oncological, gynaecological).
The study will allow to:
- Provide biological samples (faeces, saliva, vaginal, urine) from healthy volunteers and patients suffering from selected disease to the first Italian microbiota biobank;
- Study microorganisms using different in vitro and in vivo techniques;
- Study the link between the microbiota and the disease. This study is part of the BIOMIS project (Project Code: ARS01_01220), presented as part of the "Avviso per la presentazione di progetti di ricerca industriale e sviluppo sperimentale nelle 12 aree di specializzazione individuate dal PNR 2015-2020" and admitted to funding under the National Operational Program "Ricerca e Innovazione" 2014-2020 by directorial decree of MIUR - Department for Higher Education and Research - n. 2298 of 12 September 2018. BIOMIS includes several clinical studies that enrol patients with different pathologies to collect and store biological samples and study microbiota.
详细描述
The primary aim of this monocentric study is to populate the first national microbioma biobank with biological samples (fecal, salivary, urinary and vaginsl samples) subjects suffering from selected disease disease and healthy volunteers.
The secondary aim is the characterization of microorganisms of the biobank and study of the microbiota-pathology relationship using meta-omics, in vitro and in vivo approaches, The study plans to enrol 100 subjects at Policlinic of Bari, according to the inclusion/exclusion criteria. The study participation is voluntary, and the subjects have the right to withdraw from the study at any time and for any reason.
During the study, 3 visits are planned:
- Visit 0 (V0), including description of the objectives and procedures study, signature written informed consent, inclusion/exclusion criteria evaluation, medical examination (blood pressure measurement, abdominal and thoracic physical examination), filling in of the anamnestic questionnaire, delivery of kits for the collection of fecal, salivary and urinary material to be reported at Visit 1 and delivery of a 3-day food diary, to be completed autonomously in the days preceding the Visit 1.
- Visit 1 (V1) - at least 4 days after V0, including delivery of the of the collected biological material (feces, saliva, urine), and of a 3-day food diary, filling in of the new signs and symptoms anamnestic questionnaire and collection of the vaginal swab by medical staff.
- Telephone evaluation: administration of a "Food Frequency Questionnaire" to assess the subjects' alimentary habits.
Standard Operative Procedures (SOP) for samples storing, transport and processing will be adopted to ensure samples stability and grant results validity and quality.
