A woman in her 20s with a recent diagnosis of Crohn's disease (CD) affecting the ileocaecal valve was started on adalimumab, after routine tuberculosis (TB) tests were negative. Her abdominal symptoms got worse and she started presenting respiratory distress and fever. Tomography revealed a left pleural effusion, pneumonia and peritonitis with pelvic abscess. The diagnosis of disseminated TB with digestive involvement was suggested and sputum cultures were positive for Treatment for TB was started and immunosuppressants discontinued, leading to respiratory improvement. Abdominal imaging was repeated, showing worsening signs of multisegmental ileal wall thickening, ileocaecal valve obstruction and a persistent pelvic abscess. She was then submitted to a laparoscopic ileocaecal resection for suspicion of worsening CD. Histopathology showed chronic ileocolitis compatible with CD and ganglionic tuberculosis, revealing the diagnosis of intestinal tuberculosis superimposed in CD. Recovery was uneventful.

Crohn's disease (CD) is a chronic, complex inflammatory disorder of the gastrointestinal tract that presents significant therapeutic challenges. Despite the availability of a wide range of treatments, many patients experience primary non-response, secondary loss of response, or adverse events, limiting the overall effectiveness of current therapies. Clinical trials often report response rates below 60%, partly due to stringent inclusion criteria.

Cell-type-specific contributions to CD etiology and genetic risk are incompletely understood. Here we built a comprehensive atlas of cell-type- resolved chromatin accessibility comprising 557,310 candidate cis-regulatory elements (cCREs) in terminal ileum and ascending colon from patients with active and inactive CD and healthy controls.

The increasing focus of small extracellular vesicles (sEVs) in liquid biopsy has created a significant demand for streamlined improvements in sEV isolation methods, efficient collection of high-quality sEV data, and powerful rapid analysis of large data sets. Herein, we develop a high-throughput dual-use mass spectroscopic chip array (DUMSCA) for the rapid isolation and detection of plasma sEVs. The DUMSCA realizes more than a 50% increase in speed compared to traditional method and confirms proficiency in robust storage, reuse, high-efficiency desorption/ionization, and metabolite quantification.

Objectives: We aimed to evaluate the effectiveness and safety of clinical decision support tool (CDST)-guided initial selective intensive induction therapy (IIT) for patients with Crohn's disease (CD) who were treated with ustekinumab (UST) and to identify those most likely to benefit from IIT.
Methods: Patients with active CD were included in this multicenter retrospective study and were categorized as low-, intermediate-, and high-probability responders according to the UST-CDST. IIT was defined as intensive induction by two or three initial doses of weight-based intravenous UST administration.
