RESUMO
BACKGROUND: Acute gastrointestinal GvHD (GI-aGvHD) refractory to first-line treatment with systemic corticosteroids is resulting in death in the majority of patients. We prospectively assessed the feasibility and efficacy of regional intra-arterial steroid treatment in adult patients with severe (≥ grade III) GI-aGvHD not responding to first-line treatment. PATIENTS AND METHODS: Patients with more than +++ GI-aGvHD not responding to intravenous methylprednisolone at a dose of 2mg/kg/day were eligible for inclusion. Catheter guided intra-arterial steroid administration (IASA) was performed into the superior and inferior mesenteric artery. RESULTS: 12 consecutive patients with steroid-refractory grade III GI-aGvHD received IASA as second-line treatment. 83% of patients had gastrointestinal response including four patients (33%) with complete response at 28 days after IASA. 5/12 patients were alive at a median time of 531 days. CONCLUSION: Regional treatment of severe GVHD with IASA treatment seems to be a safe and effective second-line treatment for steroid-refractory GI-aGvHD in adult patients.

INTRODUCTION: Preexisting electrocardiographic abnormalities may limit accuracy of continuous electrocardiography (cECG) for ischemia determination. The American College of Cardiology/American Heart Association published criteria for the exclusion of unsuitable cECG curves from ST-segment interpretation. These criteria consider medication and 12-lead ECG findings (medication- and 12-lead ECG-based criteria) and cECG lead characteristics (cECG-based criteria). METHODS: We recorded cECG in 300 patients undergoing major noncardiac surgery. We determined postoperative troponin and 12-month outcome. We compared the associations of cECG-detected ischemia with troponin and 12-month outcome with and without adherence to the criteria. RESULTS: Adherence to the medication- and 12-lead ECG-based criteria enhanced the association between troponin and perioperative ischemia in CM5 (odds ratio, 3.74; 95% confidence interval, 1.88-7.44) and 7.03 (2.67-18.49), respectively; P = .049). Similarly, the association between ischemia in CM5 and 12-month outcome tended to increase (P = .081). CONCLUSIONS: Applying the guideline criteria for the interpretation of cECG enhanced cECG diagnostic value in surgical patients.
