DOCK8 deficiency is a rare inherited combined immunodeficiency, caused by mutations in the DOCK8 gene. We describe a case with DOCK8 deficiency associated with severe CLD in whom orthotopic LT was performed successfully after allogeneic HSCT. A 5 year-old girl with DOCK8 deficiency presented with mild direct hyperbilirubinemia and abnormal GGT level and without a previous history of jaundice. She had severe growth retardation, hepatosplenomegaly and generalized eczema. Progressive worsening of CLD was observed within 4 months. Investigations for etiology of liver disease were negative. Liver biopsy showed bridging necrosis, cholestasis and, cirrhosis. Recurrent immune hemolytic crisis and several viral infections developed in follow-up. She underwent whole cadaveric LT for end-stage liver disease (ESLD) 1 year after allogenic HSCT from a full matched related donor. The postoperative course was uneventful. The patient is alive with normal liver function and moderate skin graft versus host disease for 36 months after LT. In conclusion DOCK8 deficiency can be associated with severe CLD. Successful LT following HSCT is possible in patients with ESLD in DOCK8 deficiency. The timing of LT is challenging in patients requiring both HSCT and LT since conditioning regimens for HSCT can be highly hepatotoxic and the patients with suboptimal liver function can become decompensated during HSCT.

Intestinal transplantation (ITx) is the treatment of choice for patients with intestinal failure who have developed life-threatening complications related to long-term parenteral nutrition. Patients may also undergo ITx as part of a combined liver-intestine or multivisceral transplant for a variety of indications, most commonly intestinal failure-associated liver disease or porto-mesenteric thrombosis. Endoscopy plays a critical role in the posttransplant management of these patients, most commonly in the diagnosis and management of rejection, which occurs in up to 30-40% of patients within the first-year posttransplant. With a lack of noninvasive biomarkers to identify the presence of rejection, endoscopy and biopsy remain the gold standard for its diagnosis. Endoscopic evaluation of the graft is also important in the identification of other complications post-ITx, including posttransplant lymphoproliferative disorder, graft-versus-host disease, and enteric infections. Each patient's posttransplant anatomy may be slightly different, making endoscopy sometimes technically challenging and necessitating clear and frequent communication with the surgical team in order to help identify the highest yield approach. Herein, we review the most common pathologies found endoscopically in the post-ITx patient and describe some of the unique challenges the endoscopist faces when evaluating these complex patients.

Hepatitis-associated aplastic anemia (HAAA) has been reported in 23% to 33% of patients who received orthotopic liver transplantation (LT) for acute liver disease of unknown origin (nonviral hepatitis). In this situation, hematopoietic stem cell transplantation (HSCT) might be a curative option. Here the authors report on 6 patients who received HSCT after LT for nonviral HAAA hepatitis. The outcomes were interpreted in the context of recently reported immune suppressive therapy (IST) outcomes in 8 patients with HAAA and to HSCT outcomes in patients with HAAA who recovered from hepatitis without undergoing LT. All patients transplanted by using HLA-identical sibling donors (3 out of 6) were alive and had normal liver function and hematopoiesis without graft versus host disease. Both patients receiving bone marrow from a matched unrelated donor (MUD) experienced extensive graft versus host disease that was fatal for one patient. Thereby, the authors conclude that HSCT can be considered as a first-choice treatment for this category of patients when HLA-identical donors are available. When no HLA-identical donor is available, IST should be applied as HSCT with other donor sources might be reserved for IST nonresponders or poor responders.
