BACKGROUND
Little is known about the safety and efficacy of using two or more biologics for the treatment of immune-mediated diseases, including Crohn’s disease (CD).
CASE SUMMARY
This case report and narrative review demonstrate the potential safety of dual biologic therapy (DBT) in a 45-year-old female with two separate immune-mediated diseases. She had a history of multiple sclerosis for which she was receiving treatment with ocrelizumab, and she had been recently diagnosed with CD after presenting with diarrhoea. The CD diagnosis was confirmed radiologically, endoscopically, histologically, and biochemically. The patient received treatment with vedolizumab, a gut-specific inhibitor of the α4β7 integrin on leukocytes. No adverse reactions were observed for the duration of treatment. The safety of ocrelizumab and vedolizumab for the treatment of different immune-mediated diseases was demonstrated.
CONCLUSION
DBT may be a safe and effective option for the treatment of refractory disease or multiple immune-mediated diseases. Newer biologics, which have improved safety profiles and gut specificity, may provide promising avenues for treatment. However, caution must be exercised in the appropriate selection of biologics given their inherent immunosuppressive properties, side effects, and efficacy profiles. Current evidence suggests that biologic therapy is not associated with a worse prognosis in patients with coronavirus disease 2019, but treatment decisions should be made in a multidisciplinary setting. Further research from controlled trials is needed to better understand the safety profile of DBT in CD. The immunopathological mechanisms underlying DBT also remain to be clarified.
Core Tip: This paper describes the use of two biologics for the treatment of Crohn's disease and multiple sclerosis. Only a few papers have reported the safety and efficacy of these treatments due to inherent concerns regarding immunosuppression, infection, and malignancy. We present the case of a patient who was safely treated with vedolizumab and ocrelizumab. The combination of biologics may be a safe and effective treatment for immune-mediated diseases.
