Introduction: The advent of biotherapies has radically changed the management of IBD. However, the use of these drugs may in some cases result in to primary non-response or a loss of secondary response. Therapeutic Drug Monitoring (TDM) is a tool that was developed to manage biotherapy as accurately as possible in these situations. Material and methods: This is a retrospective descriptive study spread over 8 years of 53 patients followed for IBD put on anti-TNF(, in whom assays of residual levels of anti-TNF and anti-drug antibodies were carried out. Results: 48 suffer from Crohn’s disease and 5 from ulcerative colitis. Of these patients, 41 were on infliximab and 12 on adalimumab. The TDM performed in front of a primary non-response in 18 patients, and a loss of secondary response in 34 patients. We found immunization in 28% of patients, underdosage in 56%, and 15% had a normal dosage. Therapeutic optimization was adopted in 52% of patients, a switch in 19%, a swap in 25% of patients, and the addition of an immunosuppressant in 6.5%. The evolution was marked by the achievement of a prolonged remission in 69% of these patients. Conclusion: Pharmacological dosage of the residual rate of the anti-TNF and anti-drug antibodies currently constitutes an important element for managing the primary non-response or the loss of secondary response to anti-TNF in patients with IBD treated by biotherapy.

Retrograde endoscopic cholangiopancreatography (ERCP) retains a prominent place in the therapeutic management of bilio-pancreatic pathologies, in particular lithiasis disease. Its complications are now well known and are dominated by acute pancreatitis. The aim of our work is to assess the frequency and predictors of complications of ERCP.We retrospectively included all consecutive patients who received an ERCP, between January 2018 and April 2019 in the gastroenterology I Department of the Military Instruction Hospital Mohamed V in Rabat, for a lithiasis pathology. Clinical, biological and endoscopic data were collected from patient records.Statistical analysis was performed by Spss20 software using the binary logistic regression model in univariate and multivariate analyzes. The associated factors studied are: age, sex, history of ERCP, taking NSAIDs before the gesture, catheterization of the pancreatic duct and the number of passages in the Wirsung, the achievement of a pre-cut and the total duration of the procedure.

Severe acute colitis is a medical and surgical emergency that involves the short-term life threatening. The diagnosis of CAG is based on the combination of clinical and biological criteria and can be supported by morphological criteria (endoscopy, scanner). It complicates ulcerative colitis (UC) as well as Crohn's disease.It is a serious complication which, in the absence of proper care, in a specialized environment, is likely to jeopardize the vital prognosis. Intravenous corticosteroid therapy (CO IV) is the first-line medical treatment for AGC.The objective of our work is to assess the predictive factors of the response to intravenous corticosteroid therapy during severe acute colitis. This is an observational study spread over 2 years, covering 27 cases of severe acute colitis collected within our department. The Severe acute colitis was defined by a Lichtiger score greater than 10. Clinical, biological, endoscopic and radiological data were collected and analyzed by SPSS20 software.
