COMBINATION THERAPY OF MESENCHYMAL STROMAL CELLS AND INFLIXIMAB IN UNCOMPLICATED (LUMINAL) CROHN DISEASE

Abstract

AIMS. To investigate the efficacy of combination therapy using bone marrow-derived mesenchymal stromal cells (MSC) and Infliximab (IFX) to achieve «deep remission» in patients with luminal Crohn disease (CD). METHODS. Our study included 72 patients (19-62 y old) (Ме=29) with luminal CD. Patients ini group (n=21) received standard 5-aminosalicylic acid (5-ASA) and glucocorticosteroids (GCS) therapy in combination with MSC. Patients in 2 group (n=32) were prescribed anti-cytokine therapy IFX. Patients in 3 group (n=19) received MSC and IFX. RESULTS. Clinical, immunobiological and hystological results (C-reactive protein-CRP, fecal calprotectin-FCP, Gebs scale) showed more significant decrease of local and systemic inflammation activity in 3 group of patients. During 3-year follow-up we observed the longer duration of remission in patients, received MSC and IFX compared to 1 group of patients (р=0,04) and 2 group of patients (р=0,038). CONCLUSIONS. Combination therapy of bone marrow-derived MSC and IFL provides «deep remission» in patients with luminal CD and has higher prognostic value in duration of CD remission period.
