Home Parenteral Support in Chronic Intestinal Failure-First Results from a Pioneer Portuguese Intestinal Failure Center.

Background/objectives: Home parenteral support (HPS) is the core of chronic intestinal failure (IF) treatment. For legal reasons, HPS in Portugal lags behind other European countries, and only a few patients were taken care of at home by nurses. Now, the legislation has changed, allowing patient self-care. The authors report their pioneer experience as the largest Portuguese IF center, evaluating the underlying conditions leading to IF, HPS nutritional impact, HPS-related complications and survival.

Methods: This is a retrospective study including IF patients who underwent HPS in a Portuguese IF center. The data included demographics, underlying conditions, IF types, HPS duration, BMI at the beginning and end of HPS/follow-up, complications, microbiological agents of infectious complications and current status (deceased or alive with/without HPS). Survival was calculated until death or September 2024.

Results: A total of 23 patients (52.2% female, mean age 57.3 years), all with type III IF, were included. Short bowel syndrome (SBS) was the most common cause of IF (69.6%). Of the included patients, 78.3% received home parenteral nutrition; the others received home parenteral hydration. The mean BMI increased significantly, from 19.1 kg/m to 22.5 kg/m ( < 0.001). Two patients received Teduglutide. The most common complication was catheter-related bloodstream infection (2.5/1000 catheter days). The complications did not increase with patient self-care. At the end of follow-up, 21.7% of patients remained on HPS, 34.8% were alive without HPS, and 43.5% died. The average survival was 43.4 months. One death (4.35%) was attributable to HPS-related complications.

Conclusions: The conditions underlying IF varied, with SBS being the most frequent condition. HPS improved the BMI, allowing considerable survival. Despite the complications and one attributable death, HPS was safe, even when relying on patient self-care.
