Intramuscular (IM) B12 injections using hydroxocobalamin, the preferred licensed form in the UK are recommended when: Oral supplementation has failed to correct a documented deficiency The patient has difficulty adhering to daily oral regimens Serum B12 levels remain persistently low despite adequate oral dosing There is clinical evidence of neurological or haematological complications In line with BNF guidance, the standard IM regimen for confirmed deficiency without neurological involvement is a loading course of 1 mg hydroxocobalamin on alternate days for two weeks , followed by maintenance of 1 mg every three months

Key pathophysiologic mechanisms include: Mucosal barrier dysfunction: Impaired epithelial tight junctions allow bacterial translocation, triggering innate immune activation T-helper cell dysregulation: Predominantly Th1 and Th17 pathways drive chronic inflammation via TNF-, IL-12, IL-23 the basis for biologic therapy targets Transmural inflammation: Unlike UC (mucosal only), CD involves all layers: mucosa submucosa muscularis propria serosa Granuloma formation: Non-caseating granulomas are pathognomonic but present in only ~3050% of biopsies Fibrosis and stricture: Chronic inflammation activates myofibroblasts collagen deposition luminal narrowing obstructive symptoms Fistula formation: Transmural ulcers penetrate serosa form sinus tracts connect to adjacent bowel, bladder, vagina, or skin 7
For this reason, a relatively high starting concentration was needed to reliably induce the phenotype being studied
