Prevalence and risk factors for complications in adult patients with short bowel syndrome receiving long-term home parenteral nutrition.

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 HPNassociated complications in adult patients with SBS, especially the catheter-related sepsis and HPN-associated liver/biliary disorders.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 χ2 test were applied to compare the differences between the two groups.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).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.
