MAIN OBJECTIVE: Description of predicted markers of acute diverticulitis crisis, using bivariate and multivariate analyses. Analysis of acute diverticulitis predictor swings.
SIDE OBJECTIVES: Descriptive analysis of HRQL in the different measurement periods to establish the evolution of the disease. Correlate HRQL values of systemic and local inflammatory markers in the diverticulitis group. Sub-analysis of patients with immunosuppression to evaluate disease virulence compared to a group of patients without immunosuppression.
STUDY TYPE: Clinical, observational, prospective and multicenter study (8 hospitals) with three study groups: patients diagnosed with acute diverticulitis attending emergencies, diverticulosis patients and patients without diverticulums. INCLUSION CRITERIA: Age > 18years and radiological diagnosis by abdominal CT acute diverticulitis. EXCLUSION CRITERIA: Rejection of the patient -severe diverticulitis requiring urgent surgery -an inability to understand HRQL questionnaire - IBD - pregnancy or breastfeeding - acute diverticulitis within the prior year of the study - Roma IV criteria fulfilment. VARIABLES: Main variables: local and systemic inflammatory markers- faecal calprotectin. Secondary variables: recurrence of acute diverticulitis -the persistence of symptoms - SF 12 and GIQLI questionnaires.
STATISTICS: Sample size: alpha error 0.05; beta error 0.20; bilateral; proportion 0.9 in the control group; 500 subjects group diverticulitis, 200 group diverticulosis and not diverticulums.

Patients with acute diverticulitis episode
Patients diagnosed with diverticulosis without any acute diverticulitis episode
Patients without diverticulosis
- Recurrence of acute diverticulitis [ Time Frame: 2 years ]To detect which patients with acute diverticulitis recur
- Systemic inflammatory markers [ Time Frame: 2 years ]
To correlate systemic inflammatory markers with acute diverticulitis recurrence.
* Systemic inflammatory markers include: A blood test with leukocyte count and formula, C-reactive protein, albumin, Neutrophil-Lymphocyte ratio calculation, Platelet-lymphocyte ratio calculation, lymphocyte-monocyte ratio calculatio, Modified Glasgow Prognostic score calculation.
- Faecal calprotectine [ Time Frame: 2 years ]To correlate faecal calprotectine with acute diverticulitis recurrence
- Local inflammatory markers [ Time Frame: 2 years ]
To correlate local inflammatory markers with systemic inflammatory markers and recurrence.
*Local inflammatory markers come from colonic endoscopic samples taken in the colonoscopy at 2 months after the acute diverticulitis episode. 2 samples are taken:
- Sample A: 1-5cm of diverticulum that has participated in diverticulitis episode (correlated with the CT)
- Sample B: 30cm of the area that has suffered diverticulitis. Sampling for the study of local inflammatory markers includes IL-6, IL-10, tumour necrosis factor (TNF), macrophages, eosinophils and calculation of inflammation index of Ulcerative Colitis.
- HRQL (Health Related Quality of Life) QUESTIONNAIRES [ Time Frame: 2 years ]
To correlate clinical symptoms with inflammatory markers.
- SF-12 Health Survey, in order to measure Mental and Physical Health. There are 8 areas with a minimum value of 0 (the worst health state) and a maximum of 100 (best health state)
- GIQLI (Gastrointestinal Quality of Life questionnaire). Minimum value of 0 (the worst health state) and a maximum of 100 (best health state)
