Recent advances in the management of pediatric intestinal failure

ASPEN definitions in pediatric intestinal failure

Pediatric intestinal failure (PIF) is a relatively rare disease entity which requires focused interdisciplinary care and specialized nutrition management. There has long been a lack of consensus in the definition of key terms related to PIF due to its rarity and plethora of small studies rather than large trials. As such, the American Society for Parenteral and Enteral Nutrition (ASPEN) Pediatric Intestinal Failure Section, composed of clinicians from a variety of disciplines caring for children with intestinal failure, is uniquely poised to provide insight into this definition void. This document is the product of an effort by the Section to create evidence-based consensus definitions, with the goal of allowing for appropriate comparisons between clinical studies and measurement of longterm patient outcomes.

Pediatric short bowel syndrome and subsequent development of inflammatory bowel disease: an illustrative case and literature review

Short bowel syndrome (SBS) in neonates is an uncommon but highly morbid condition. As SBS survival increases, physiologic complications become more apparent. Few reports in the literature elucidate outcomes for adults with a pediatric history of SBS. We present a case report of a patient, born with complicated gastroschisis resulting in SBS at birth, who subsequently developed symptoms and pathologic changes of inflammatory bowel disease (IBD) as an adult. The patient lived from age 7, after a Bianchi intestinal lengthening procedure, to age 34 independent of parenteral nutrition (PN), but requiring hydration fluid via G-tube. He was then diagnosed with IBD, after presenting with weight loss, diarrhea, and malabsorption, which required resumption of PN and infliximab treatment. This report adds to a small body of the literature which points to a connection between SBS in neonates and subsequent diagnosis of IBD. Recent evidence suggests that SBS and IBD have shared features of mucosal immune dysfunction and altered intestinal microbiota. We review current treatment options for pediatric SBS as well as multidisciplinary and coordinated transition strategies. We conclude that there may be an etiologic connection between SBS and IBD and that this knowledge may impact outcomes and approaches to care.

Intestinal transplantation in children: current status

Intestinal transplantation (IT) is the least common form of organ transplantation; however, it has shown exceptional growth and improvement in graft survival rates over the past two decades mainly due to better outcomes achieved during the first year of transplantation (76 % at 1 year), due to improvement in surgical techniques and the development of better immunosupressive therapies as we understand more about the relationship between the recipient and host immune system. There are still ongoing issues with chronic rejection and long-term survival. Intestinal transplantation is still an acceptable therapy for patients with intestinal failure (IF), but it is generally reserved for patients who develop severe and life-threatening complications despite standard therapies, or those who are not able to maintain a good quality of life. The purpose of this review is to describe the current status, indications, outcomes and advances in the field of intestinal transplantation.

Central Venous Access in the Pediatric Population With Emphasis on Complications and Prevention Strategies

Central venous catheters are often necessary in the pediatric population. Access may be challenging, and each vessel presents its own unique set of risks and complications. Central venous catheterization is useful for hemodynamic monitoring, rapid fluid infusion, and administration of hyperosmolar medications, including vasopressors, antibiotics, chemotherapy, and parenteral nutrition. Recent advances have improved the catheters used as well as techniques for insertion. A serious complication of central access is infection, which is associated with morbidity, mortality, and significant financial costs. Reduction of catheter-related bloodstream infections is realized with use of ethanol locks, single lumens when appropriate, and prudent adherence to insertion and maintenance bundles. Ultrasound guidance used for central venous catheter placement improves accuracy of placement, reducing time and unsuccessful insertion and complication rates. Patients with central venous catheters are best served by multidisciplinary team involvement.
