Amyloidosis is a rare but serious complication of inflammatory bowel disease (IBD), especially Crohn's disease (CD). It occurred in 15 of our 1709 patients with CD (0.9%) (706 with ileocolitis, 310 with colitis, and 693 with enteritis), but in only 1 of our 1341 patients with ulcerative colitis (UC) (0.07%), admitted to The Mount Sinai Hospital between 1960 and 1985. Eleven of the patients with CD who had amyloidosis had ileocolitis, 2 colitis, and 2 ileitis; these figures represent a frequency within each group of 1.6%, 0.6%, and 0.3%, respectively. Amyloidosis was thus associated 4.4 times more often with CD of the colon than with pure small bowel disease. We have added to this group of 15 patients the 5 cases of CD that were originally reported by Werther et al in 1960, plus another 4 (2 with UC and 2 with CD) who have been seen since 1985, making a total of 25 patients in this series, 22 with CD and 3 with UC. There was a striking male preponderance, 16 of 22, among patients with CD, although 2 of the 3 patients with UC were female. Amyloid disease was diagnosed at a mean age of 40 years, 15 years (range, 1-42) after the onset of CD. Six major forms of amyloidosis occurred: nephropathy, enteropathy, cardiomyopathy, hepatosplenomegaly, thyroid mass, and generalized amyloidosis. Renal disease with proteinurea and/or renal insufficiency occurred in 18 of the 22 patients with CD and in all 3 with UC. Nephropathy was by far the most common lethal manifestation of IBD-associated amyloidosis in this series. Nephrotic syndrome developed in 15 patients with CD and was accompanied by renal failure, the major contributor to mortality, in 10 of the 13 patients who died. Amyloidosis may be associated with suppurative or other extraintestinal manifestations of IBD. Fifteen of the 22 patients with CD who had amyloidosis also had suppurative complications of their bowel disease, although the other 7 had no recognizable suppuration. Extraintestinal manifestations were also common in this series, occurring in 12 of 22 patients with CD and in 2 of the 3 patients with UC; 6 of the 18 patients with nephrotic syndrome also had arthritis. However, there is no evidence that patients with IBD with amyloidosis have extraintestinal manifestations more frequently than do IBD patients without amyloidosis. Earlier reports of amyloid associated with IBD came from autopsy series. In recent years, biopsy has allowed diagnosis to be made during life.(ABSTRACT TRUNCATED AT 400 WORDS)

Very early onset inflammatory bowel disease (VEO-IBD) represents a diagnostic and treatment challenge. Here we present a case of VEO-IBD secondary to a mutation in BIRC4 gene, which encodes X-linked inhibitor of apoptosis protein (XIAP), in a 17-month-old boy with severe failure to thrive, intractable diarrhea, and hepatosplenomegaly. Endoscopy and histology identified only mild duodenitis and ileitis, but severe pancolitis with crypt abscesses and epithelium apoptosis. Minimal improvement in symptoms was achieved with total parenteral nutrition (TPN), intravenous (IV) corticosteroids, and tacrolimus, whereas induction and maintenance therapy with adalimumab led to complete remission. After 6 months, the patient developed hemophagocytic lymphohistiocytosis and eventually died due to multisystem organ failure. A review of the literature revealed that some patients with VEO-IBD secondary to XIAP deficiency develop symptoms that are refractory to medical and surgical management, while initial reports suggest that allogeneic hematopoietic stem cell transplantation (HSCT), with reduced intensity conditioning, can successfully induce long-lasting remission and may even be curative. We propose that in patients with XIAP deficiency a constellation of symptoms including colitis at an early age, severe failure to thrive, and splenomegaly/hepatosplenomegaly can identify a subgroup of patients at high risk of experiencing medically refractory IBD phenotype and increased mortality. Hematopoietic stem cell transplant should be considered early in these high-risk patients, as it may resolve both their intestinal inflammation and a risk of developing life threatening hemophagocytic lymphohistiocytosis .
