  1. Patients with gastrointestinal symptoms (diarrhea, abdominal pain or discomfort, nausea/vomiting) were tested for anti-SARS-CoV-2 IgA and IgG in the serum at the time of admission. Maximum serum ferritin and serum IL-6 represent the maximum ferritin and IL-6 serum concentration measured during the time of hospitalization. GI gastrointestinal, EGD esophagogastroduodenoscopy, IEL intraepithelial lymphocytes, qRT-PCT quantitative RT-PCR, na not available, abd. abdominal, IHC immunohistochemistry for SARS-CoV-2 nucleocapsid; 1patients presented with GI symptoms at the time of admission; 2Patients developed GI symptoms during their stay in the hospital.
