BACKGROUND: Idiopathic thrombocytopaenic purpura [ITP] is an acquired haematological disorder with an incidence of 1-6 per 100 00/year. ITP and inflammatory bowel disease [IBD] comorbidity has been reported in the literature, but insights regarding the course, outcome and optimal management are limited by its rarity. The current study aimed to evaluate the clinical presentation and outcome of ITP in patients with IBD. METHODS: This multicentre retrospective case series was performed as part of the ECCO Collaborative Network of Exceptionally Rare case reports [CONFER] project. Cases of patients with ITP and IBD were collected by participating investigators. Clinical data were recorded in a standardized collection form. RESULTS: This report includes 32 patients with concurrent ITP and IBD: ten were females, and the median age was 32.0 years (interquartile range [IQR] 20.5-39.5). Fourteen patients had a diagnosis of Crohn's disease [CD] and the other 18 ulcerative colitis [UC]. The diagnosis of IBD preceded the ITP in 26 patients (median time between diagnoses was 7.0 years [IQR, 1.5-9.5]). Among those patients, 17 were in clinical remission at ITP diagnosis. Thirteen patients were treated with mesalamine, four with oral corticosteroids, one with rectal corticosteroids, two with azathioprine and five with anti-tumour necrosis factor agents. The median platelet count was 35 000/microliter [IQR, 10 000-70 000]. Eight patients had rectal bleeding, 13 had skin purpura, three had epi...
