    Abstract Background: As real-world data on risankizumab in patients with moderate to severe Crohn's disease (CD) are scarce, we evaluated its effectiveness and safety in multirefractory Belgian patients.
    Methods: Data from consecutive adult CD patients who started risankizumab before April 2023 were retrospectively collected at 6 Belgian centers. Clinical remission and response were defined using the 2-component patient-reported outcome. Endoscopic response was defined as a decrease in baseline Simple Endoscopic Score with ≥50%. Both effectiveness end points were evaluated at week 24 and/or 52, while surgery-free survival and safety were assessed throughout follow-up.
    Results: A total of 69 patients (56.5% female, median age 37.2 years, 85.5% exposed to ≥4 different advanced therapies and 98.6% to ustekinumab, 14 with an ostomy) were included. At week 24, 61.8% (34 of 55) and 18.2% (10 of 55) of patients without an ostomy achieved steroid-free clinical response and remission, respectively. At week 52, these numbers were 58.2% (32 of 55) and 27.3% (15 of 55), respectively. Endoscopic data were available in 32 patients, of whom 50.0% (16 of 32) reached endoscopic response within the first 52 weeks. Results in patients with an ostomy were similar (steroid-free clinical response and remission, 42.9% and 14.3%, respectively). During a median follow-up of 68.3 weeks, 18.8% (13 of 69) of patients discontinued risankizumab, and 20.3% (14 of 69) of patients underwent CD-related intestinal resections. The estimated surgery-free survival at week 52 was 75.2%. No new safety issues were observed.
    Conclusions: In this real-world cohort of multirefractory CD patients, risankizumab was effective in inducing both clinical remission and endoscopic response. Risankizumab was well tolerated with no safety issues.

    Abstract Transcription termination factor Rho is a ring-shaped, ATP-dependent molecular motor that targets hundreds of transcription units in Escherichia coli. Interest in Rho was renewed recently on the realization that this essential factor is involved in multiple interactions and cellular processes that protect the E. coli genome and regulate its expression on a global scale. Yet it is currently unknown if (and how) Rho-dependent mechanisms are conserved throughout the bacterial kingdom. Here, we mined public databases to assess the distribution, expression and structural conservation of Rho across bacterial phyla. We found that rho is present in more than 90 % of sequenced bacterial genomes, although Cyanobacteria, Mollicutes and a fraction of Firmicutes are totally devoid of rho. Genomes lacking rho tend to be small and AT-rich and often belong to species with parasitic/symbiotic lifestyles (such as Mollicutes). By contrast, large GC-rich genomes, such as those of Actinobacteria, often contain rho duplicates and/or encode Rho proteins that bear insertion domains of unknown function(s). Notwithstanding, most Rho sequences across taxa contain canonical RNA-binding and ATP hydrolysis signature motifs, a feature suggestive of largely conserved mechanism(s) of action. Mutations that impair binding of bicyclomycin are present in ~5 % of rho sequences, implying that species from diverse ecosystems have developed resistance against this natural antibiotic. Altogether, these findings assert that Rho function is widespread among bacteria and suggest that it plays a particularly relevant role in the expression of complex genomes and/or bacterial adaptation to changing environments.

    Abstract The bacterial transcription termination factor Rho-a ring-shaped molecular motor displaying directional, ATP-dependent RNA helicase/translocase activity-is an interesting therapeutic target. Recently, Rho from Mycobacterium tuberculosis (MtbRho) has been proposed to operate by a mechanism uncoupled from molecular motor action, suggesting that the manner used by Rho to dissociate transcriptional complexes is not conserved throughout the bacterial kingdom. Here, however, we demonstrate that MtbRho is a bona fide molecular motor and directional helicase which requires a catalytic site competent for ATP hydrolysis to disrupt RNA duplexes or transcription elongation complexes. Moreover, we show that idiosyncratic features of the MtbRho enzyme are conferred by a large, hydrophilic insertion in its N-terminal 'RNA binding' domain and by a non-canonical R-loop residue in its C-terminal 'motor' domain. We also show that the 'motor' domain of MtbRho has a low apparent affinity for the Rho inhibitor bicyclomycin, thereby contributing to explain why M. tuberculosis is resistant to this drug. Overall, our findings support that, in spite of adjustments of the Rho motor to specific traits of its hosting bacterium, the basic principles of Rho action are conserved across species and could thus constitute pertinent screening criteria in high-throughput searches of new Rho inhibitors.

    Abstract Transcription termination factor Rho is a ring-shaped, homo-hexamieric RNA translocase that dissociates transcription elongation complexes and transcriptional RNA-DNA duplexes (R-loops) in bacteria. The molecular mechanisms underlying these biological functions have been essentially studied with Rho enzymes from Escherichia coli or close Gram-negative relatives. However, phylo-divergent Rho factors may have distinct properties. Here, we describe methods for the preparation and in vitro characterization (ATPase and helicase activities) of the Rho factor from Mycobacterium tuberculosis, a specimen with uncharacteristic molecular and enzymatic features. These methods set the stage for future studies aimed at better defining the diversity of enzymatic properties of Rho across the bacterial kingdom.

    Abstract Recently, concerns were raised of high rates of HCC recurrence in patients treated with direct-acting antivirals (DAA) for hepatitis C infection. We investigated the HCC occurrence and recurrence rates within 6 months after treatment with DAA with or without pegylated interferon (PEG-IFN) in real life. This is a retrospective, multicenter cohort trial, executed in 15 hospitals distributed across Belgium. Populations were matched based on fibrosis score (Metavir F3-F4). Patients with a Child-Pugh score ≥ B were excluded. In total, 567 patients were included, of whom 77 were treated with PEG-IFN+DAA between 2008 and 2013 and 490 with DAA without PEG-IFN between 2013 and 2015. Patients treated with PEG-IFN+DAA (53±9y) were younger than patients treated with DAA without PEG-IFN (59±12y) (P=.001). 47% of patients treated with PEG-IFN+DAA were in the F4 stage vs 67% of patients treated with DAA without PEG-IFN (P=.001). Screening was inadequate in 20% of both patient groups (P=.664). The early occurrence rate of HCC was 1.7% and 1.1% in patients treated with DAA with and without PEG-IFN, respectively (P=.540). The early recurrence rate was 0% in patients treated with PEG-IFN+DAA and 15.0% in patients treated with DAA without PEG-IFN (P=.857). There is no difference in early occurrence of new HCC between patients treated with DAA with and without PEG-IFN. We did observe a high early recurrence rate of HCC in patients treated with DAA without PEG-IFN. However, these patients were at baseline more at risk for HCC. Finally, in 20%, screening for HCC was inadequate.
