Induction of remission with tacrolimus in a patient with severe acute, cortisone refractory ulcerative colitis and severe Covid-19 pneumonia: a case report

Abstract

Abstract Background Therapy regimens used in patients with inflammatory Bowel Disease (IBD) have been associated with enhanced risk of viral infections or viral reactivation. Moreover, it is uncertain whether IBD patients have increased risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or infected patients may have an increased risk for severe coronavirus disease 2019 (Covid-19). Managing severe acute flare in ulcerative colitis during the Covid-19 pandemic is a challenge for clinicians and their patients. The results of the published studies mainly report on the role of the prior medication, but not how to treat severe acute flare of IBD patients with severe Covid-19 pneumonia. Case presentation We report the case of a 68-year-old patient with a long history of ulcerative colitis. He was initially admitted to an external hospital because of severe acute flare. The initiation of a high-dose oral cortisone therapy did not improve the clinical symptoms. During the inpatient treatment, he was tested positive for SARS-CoV-2. At admission to our hospital the patient showed severe flare of his ulcerative colitis and increased Covid-19 symptoms. A cortisone-refractory course was noticed. After detailed multidisciplinary risk–benefit assessment, we initiated an intravenous tacrolimus therapy and dose of prednisolone was tapered gradually. After clinical response, the therapy was adjusted to infliximab. Additionally, the Covid-19 pneumonia was kept under control despite immunosuppression and the patient could be discharged in clinical remission. Conclusions This case suggest the use of tacrolimus as a bridging therapeutic option for severe acute, cortisone refractory ulcerative colitis in Covid-19 patients. Nevertheless, the best treatment strategy for IBD patients presenting a flare during the outbreak has yet to be defined. Further data for IBD patients under calcineurin inhibitor therapy are urgently needed.
