Primary
| Measure | Time frame |
|---|---|
| Main Objective: To investigate whether the proportion of patients with clinically significant endoscopic recurrence (Rutgeerts grades i2b, i3 and i4) at 6 months after preventive treatment with vitamin D is different from the patients treated with placebo --> the antiinflammatory effect of Vitamin D3;Secondary Objective: - The proportion of patients in clinical remission. - The influence of vitamin D treatment based on patients’ NOD2/CARD15 genotype. - Quality of life ;Primary end point(s): Endoscopic recurrence at 6 months postoperatively;Timepoint(s) of evaluation of this end point: 6 months after randomization | — |
Secondary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: 6 monhts after randomization;Secondary end point(s): - Clinical Recurrence rate at 6 months - Difference in significant recurrence among all patients with low vitamin D at baseline - The difference in response to vitamin D treatment in patients with NOD2 mutation versus patients without NOD2 mutation - To investigate if the urine metabolome is different in patients responding to vitamin D treatment - Quality of life | — |
