Introduction: Short Bowel Syndrome (SBS) is a rare gastrointestinal disorder associated with Intestinal Failure (SBS-IF) that leads to morbidity, mortality, and a burden on healthcare costs. Intestine Transplantation (IT) is a treatment option for patients with SBS-IF as it replaces the missing or diseased intestine and offers the potential for return to normal activities and intestinal function. This study aims to describe the clinical course and demographical and clinical characteristics of subjects with SBS-IF who underwent IT in Brazil., Methods: This retrospective observational study included all SBS-IF patients who underwent IT in two reference centers in Brazil from April 2011 to December 2021., Results: A total of 7 young male participants were included in the study. The most frequent underlying condition was surgical complications, followed by intestinal volvulus and incisional hernia. The most frequent indication for IT was a hepatic disease associated with total Parenteral Nutrition (PN). The main type of IT performed was intestine only. The median time from underlying condition to IT was 67.3 (16.5‒88.5) months. The mean (SD) number of yearly hospitalizations per patient was 0.5 (0.3). The most common reason for hospitalization was PN-related complications. Sixty exams were performed in-hospital and 53 in the outpatient setting., Conclusion: The findings of this study may be helpful to understand better the journey of patients with SBS-IF to IT in Brazil, providing real-world evidence to develop health policy guidelines and improve the quality of life of these patients., Competing Interests: Declaration of competing interest The authors declare the following conflicts of interest: YLB; MHMR; LH; RAAP: ADWL: APCSB; IC; GGR; FM; and LACA: Has acted as speaker in Takeda Distribuidora Ltda in medical-scope events.

Objective: Because short bowel syndrome is associated with iron deficiency, the objective of the present study was to monitor ferremia after the ingestion of different iron compounds and doses in enterectomized patients., Methods: This was a randomized, double-blind, cross-over study conducted in 13 patients of both sexes in the metabolic unit of Hospital das Clínicas de Faculdade de Medicina de Ribeirão Preto-Universídade de São Paulo and was divided into two stages. Three different iron compounds, ferrous sulfate (FS), sodium iron ethylenediaminetetra-acetic acid (EDTA), and dehydrated cell fraction (DCF), were studied. The patients were randomly assigned to one of four groups receiving high-dose DCF (120mg) and low-dose DCF (5mg) and the two iron compounds. The subjects (n=7) receiving high-dose DCF participated in 2 test days. All patients receiving the physiologic dose (low-dose DCF, n=6) participated in 3 test days with a 1-mo interval between compounds. After an 8-h fast, blood samples were collected at 0.25, 0.5, 1, and 2h. Serum iron curve and the sum of the area under the curve were calculated and adjusted according to a mixed-effect linear model (P<0.05)., Results: Serum FS levels were higher in the 120-mg group compared with the others (P<0.005). The mean areas under the curve for FS and EDTA at the doses of 120 and 5mg of elemental iron were 238, 224, 177, and 153 microg/dL, respectively. The mean area under the curve for DCF was 165 microg/dL, with no significant difference between groups., Conclusion: Regardless of dose, FS was the compound that resulted in higher ferremia compared with the other doses and compounds.

Intestinal failure is the patient's inability to maintain hydroelectric and nutritional support by the digestive route, arising from massive enterectomy or diseases in which the bowel is incapable of adequately absorbing fluids and nutrients. Patients with intestinal failure associated with short bowel syndrome (SBS) and with other functional diseases with malabsorption or with total parenteral nutrition-related complications (recurrent sepsis and thrombosis of one or more deep venous accesses) are candidates for small bowel transplantation (SBT), which can be an isolated small bowel, a combined liver and small bowel, or a multivisceral graft. At our institution, three isolated SBTs were performed as our initial experience with this transplant.
