Background and Objectives: Short bowel syndrome (SBS) is a complicated and challenging disease where home parenteral nutrition (HPN) is widely used. The complications of long-term HPN-dependent in adult patients with SBS are poorly documented. This study was mainly aimed to assess the prevalence and risk factors of HPN-associated complications in adult patients with SBS, especially the catheter-related sepsis and HPN-associated liver/biliary disorders. Methods and Study Design: 47 non-malignant adult patients with SBS who received HPN for more than 2 years in our clinical nutrition center were included. Patients were divided into two groups according to whether HPN-associated complications were present or not. Student's t-test and χ^2 test were applied to compare the differences between the two groups. Results: The mean frequency of catheter-related sepsis was 0.31±0.05 per catheter year of HPN. An higher incidence of catheter-related infections (p<0.001) and shorter delay between HPN onset and first infection (p<0.001) were identified as risk factors for catheter-related sepsis. A total of 25 patients (53.2%) developed HPN-associated liver/biliary diseases. The identified risk factors for HPNassociated liver/biliary disorders were higher rate of catheter-related infections (p=0.009), shorter delay between HPN onset and first infection (p=0.017), higher energy content of HPN (p=0.014), higher glucose rate of HPN (p=0.009), and lower lipid rate of HPN (p=0.022). Conclusion: Our study revealed that adult patients with SBS receiving long-term HPN treatment developed a low prevalence of catheter-related sepsis but a rather high prevalence of HPN-associated liver/biliary disorders. We also identified several risk factors for HPN-associated complications which should be taken notice of in clinical practice.
