“…Ischemic colitis is generated by reduced blood flow to the colon, which makes it difficult to maintain cell metabolism, which in turn leads to the acidosis, dysfunction, loss of integrity, and even the death of colon cells ( 7 , 8 ). Trauma to the mesenteric artery, vascular thrombosis or embolism, and surgical error ligation of the inferior mesenteric artery can lead to ischemic colitis, as can heart disease, hypertension, diabetes, and drugs that affect visceral blood flow ( 9 - 11 ). A previous study examined ischemic colonic mucosal injury related to natural indigo in 8 psoriasis patients who took a natural indigo compound and 5 ITP patients who took SXXBC; 5 of the patients experienced a blurred or disappeared vascular network, 7 had scattered erythema and superficial erosion of mucous membrane, and 6 had scattered superficial ulcers with longitudinal and clear boundaries ( 12 ).…”

Background: Sheng-Xue-Xiao-Ban Capsule (SXXBC), as a classic Chinese traditional medicine comprised of natural indigo, cortex moutan, forsythia, herba agrimoniae, and licorice, exhibits a heat-clearing and detoxicating function, hemostasis, and stasis dissipation, which is widely applied to treat idiopathic thrombocytopenic purpura (ITP). However, report on ischemic colitis and pulmonary embolism induced by SXXBC therapy is never disclosed. We report the case of an ITP patient who received SXXBC for ascending platelets that then induced ischemic colitis and pulmonary embolism.Case Description: A 74-year-old female patient was admitted in June 2021 due to "bleeding in stool for 1 day," she was then re-admitted in July 2021 due to "repeated bleeding in stool for 2 days". Abdominal computed tomography (CT), colonoscopy, and a pathological examination suggested ischemic colitis according to the American College of Gastroenterology (ACG) clinical guidelines. Pulmonary artery CT angiography suggested pulmonary embolism reflected by multiple filling defects, and the patient presented with shortness of breath. It was noted that the patient had started taken SXXBC for ascending platelets 2 months before the onset of hematochezia. After the diagnosis of hematochezia was made, the patient received phenethylamine and carbazochrome for hemostasis, mesalazine enteric-coated tablets for antiinflammation, and SXXBC was stopped. The hematochezia then ceased, and the ischemic colitis was attenuated. Afterwards, low-molecular-weight heparin was administered, followed by a 3-week treatment of rivaroxaban anticoagulant, which was taken orally after discharge. The pulmonary embolism was then obviously ameliorated. After excluding other causes, the patient was diagnosed with SXXBC-induced ischemic colitis complicated by pulmonary embolism. After conducting research, we came to the view that natural indigo, which is the main component of SXXBC, contributed to the patient's illness.Conclusions: Ischemic colitis complicated with pulmonary embolism are rare; however, close attention such as regular abdominal CT test needs to be paid and preventive steps such as anti-coagulant treatment could to be taken (if symptoms occur) when treating patients with SXXBC.
