Background:  Blockade of tumour necrosis factor (anti-TNF) is effective in patients with Crohn’s Disease but has been associated with infection risk and neurological complications such as demyelination. Niemann-Pick disease Type C1 (NPC1) is a lysosomal storage disorder presenting in childhood with neurological deterioration, liver damage and respiratory infections. Some NPC1 patients develop severe Crohn’s disease. Our objective was to investigate the safety and effectiveness of anti-TNF in NPC1 patients with Crohn’s disease. Methods: Retrospective data on phenotype and therapy response were collected in 2019-2020 for the time period 2014 to 2020 from patients in the UK, France, Germany and Canada with genetically confirmed NPC1 defects and intestinal inflammation. We investigated TNF secretion in peripheral blood mononuclear cells treated with NPC1 inhibitor in response to bacterial stimuli. Results: NPC1 inhibitor treated peripheral blood mononuclear cells (PBMCs) show significantly increased TNF production after lipopolysaccharide or bacterial challenge providing a rationale for anti-TNF therapy. We identified 4 NPC1 patients with Crohn’s disease (CD)-like intestinal inflammation treated using anti-TNF therapy (mean age of onset 8.1 years, mean treatment length 27.75 months, overall treatment period 9.25 patient years). Anti-TNF therapy was associated with reduced gastrointestinal symptoms with no apparent adverse neurological events. Therapy improved intestinal inflammation in 4 patients. Conclusions: Anti-TNF therapy appears safe in patients with NPC1 and is an effective treatment strategy for the management of intestinal inflammation in these patients.

A five year old girl with Neimann-Pick disease type C subsequently developed Crohn's Disease. This association has only been presented once previously in the literature. This report discusses the options for managing one chronic disease in the presence of another life limiting condition.

Niemann-Pick disease type C (NPC) has been reported in association with inflammatory bowel disease. In cases where colitis has been reported in association with NPC, the neurological manifestations of NPC often precede the development of colitis. We report a rare case of a child who presented at age 2 with perianal Crohn’s disease. Initial imaging studies to characterise the disease revealed an incidental finding of splenomegaly. Extensive workup for splenomegaly revealed NPC1 mutations consistent with NPC disease. He did not have any typical neurological symptoms at the time of his diagnosis. He is currently doing well on biweekly adalimumab injections for his Crohn’s disease and biweekly intrathecal injections of 2-hydroxypropyl-β-cyclodextrin (VTS-270) for the NPC.

The nucleotide-binding oligomerization domain protein 2, NOD2, is the pattern recognition receptor for muramyl dipeptide, a component of the cell wall of both gram-positive and gram-negative bacteria (1, 2). Sensing of muramyl dipeptide by NOD2 triggers signal transduction downstream of the RIP2 kinase to transcriptionally activate a diverse innate immune gene expression program (3-5). Single nucleotide variants in NOD2 are the strongest genetic risk factors for developing Crohn’s Disease (6, 7), an inflammatory bowel disease (8). By mining a published dataset (9), we found that among the genes whose expression changed most significantly in peripheral blood mononuclear cells (PBMC) stimulated with muramyl dipeptide, genome-wide, was the gene encoding the Wiskott-Aldrich syndrome (WAS) protein (10), a regulator of actin polymerization in hematopoietic cells (11). The WAS gene is mutated in patients with Wiskott-Aldrich syndrome (12), a genetic disorder characterized by thrombocytopenia, eczema, immunodeficiency and lymphoid malignancies (13), and whose symptoms include bloody diarrhea (14, 15). WAS RNA message was transcriptionally repressed following exposure of PBMC to muramyl dipeptide. These data link together a gene, that when mutated in humans leads to gastrointestinal symptoms not dissimilar to those found in patients with Crohn’s Disease, with the ligand for the gene whose product encodes the single most significant genetic variant conferring risk for development of Crohn’s Disease, and further suggest that the actin cytoskeleton may be a central target of gene expression changes effected by NOD2 pattern recognition of MDP.
