Proton pump inhibitors (PPIs) block the gastric H/K-ATPase, therefore inhibiting acid gastric secretion, leading to an increased pH (>4). They account for an extremely high number of prescriptions ...
Inflammatory bowel diseases (IBDs), mainly represented by Crohn’s disease (CD) and Ulcerative Colitis (UC), are chronic disorders with an unclear pathogenesis. This incurable and iterative intestinal mucosal inflammation requires the life-long use of anti-inflammatory drugs to prevent flares or relapses, which are the major providers of complications, such as small bowel strictures and intestinal perforations. The introduction of tumor necrosis factor (TNF)-alpha inhibitors and other compounds, such as anti-IL12/23 and anti-alpha4/beta7 integrin monoclonal antibodies, has considerably improved the clinical management of IBDs. They are now the standard of care, being the first-line therapy in patients with aggressive disease and in patients with moderate to severe disease with an inadequate response to conventional therapy. However, for approximately one third of all patients, their efficacy remains insufficient by a lack or loss of response due to the formation of anti-drug antibodies or compliance difficulties with parenteral formulations. To address these issues, orally administered Small Molecules Drugs (SMDs) that use a broad range of novel pharmacological pathways, such as JAK inhibitors, sphingosine-1-phosphate receptor modulators, and phosphodiesterase 4 inhibitors, have been developed for CD and UC. This article provides an updated and complete review of the most recently authorized SMDs and SMDs in phase II/III development.

Summary: Background: Children born to mothers with IBD may be exposed to anti‐TNFα agents antenatally. Current European guidelines recommend postponing live vaccines until after 6 months of life in this population. Data on the safety of live vaccines administration in the first year of life of these children are sparse with one reported fatality following bacillus Calmette‐Guerin (BCG) administration.Aims: To describe the use and safety of vaccines administered in children born to mothers with IBD and exposed antenatally to anti‐TNFα agentsMethods: Data from children born to mothers with IBD between 2013 and 2014 were collected retrospectively from the French Health Insurance Database. Vaccines recommended before or at 1 year of age were considered.Results: Among 4741 children, 670 (14.1%) were exposed to anti‐TNFα agents antenatally, with concomitant thiopurines in 16.0% (n = 107) and steroids in 19.3% (n = 214). Among these 670 children, 315 (47%) were exposed up to delivery. Exposed children were less likely than non‐exposed to receive BCG (88/670, 13.1% vs 780/4071, 19.2% respectively, P < .05) and received it later in life (months, mean ± SD, 4.3 ± 3.9 and 2.4 ± 2.9 respectively, P < .001). In exposed children, 64/88 (73%) received BCG vaccination before 6 months of age, but with no BCG‐related severe adverse event observed during the first year. Uptake of other vaccines recommended before 6 months was above 85% in both groups.Conclusion: In children exposed antenatally to anti‐TNFα agents, vaccinations are often not postponed in keeping with the recommendations, but no BCG‐related severe adverse events were reported in children vaccinated before 6 months of life.
Purpose PIK3CA pathogenic variants in the PIK3CA-related overgrowth spectrum (PROS) activate phosphoinositide 3-kinase signaling, providing a rationale for targeted therapy, but no drug has proven efficacy and safety in this population. Our aim was to establish the six-month tolerability and efficacy of low-dose taselisib, a selective class I PI3K inhibitor, in PROS patients. Methods Patients over 16 years with PROS and PIK3CA pathogenic variants were included in a phase IB/IIA multicenter, open-label single-arm trial (six patients at 1 mg/day of taselisib, then 24 at 2 mg/day). The primary outcome was the occurrence of dose limiting toxicity (DLT). Efficacy outcomes were the relative changes after treatment of (1) tissue volume at affected and unaffected sites, both clinically and on imaging; (2) cutaneous vascular outcomes when relevant; (3) biologic parameters; (4) quality of life; and (5) patient-reported outcomes. Results Among 19 enrolled patients, 2 experienced a DLT (enteritis and pachymeningitis) leading to early trial termination (17 treated, 10 completed the study). No serious adverse reaction occurred in the 1 mg cohort (n = 6). No significant reduction in affected tissue volume was observed (mean −4.2%; p = 0.81; SD 14.01). Thirteen (76.4%) participants reported clinical improvement (pain reduction, chronic bleeding resolution, functional improvement). Conclusion Despite functional improvement, the safety profile of low-dose taselisib precludes its long-term use.

Objective To pilot test the feasibility and acceptability of Simulation in Therapeutic Patient Education (S-TPE), in both adult patients with diabetes and educators. Conception Adult patients with insulin-dependent diabetes and who participated in a full TPE programme for the implementation of a FreeStyle were included in this monocentric pilot study. S-TPE intervention was based on a consensus conference determining the conditions and objectives of S-TPE. Main outcomes were the patients’ and educators’ perception of the usefulness of S-TPE and the patient’s satisfaction level at the conclusion of the simulation sequence, measured on validated scales. Secondary outcomes were organisational, human, material and temporal, facilitating and limiting factors for patients and educators, patient self-efficacy and anxiety scores. Interventions The final session of TPE used the simulation. For each group, one patient volunteered to be the simulated patient. Intervention was divided into three steps: (1) a pre-briefing, (2) a simulation of hypoglycaemia and (3) a debriefing with the group of patients and educators. The whole intervention lasted about 2 hours. Results We included 23 patients (mean age ±SD 63±15 years, 14 men) and 3 educators. After S-TPE intervention, patients’ and educators’ perceived usefulness score were 20.6/25 and 37.5/40, respectively. Patient’s satisfaction score was 51.9/60. Qualitative analysis revealed no limiting factors to implementing S-TPE. Self-efficacy was stable. Decrease in anxiety score after S-TPE reached statistical significance in women (from 35.1±4.5 to 32.7±5.5, p=0.04) but not in men. Conclusion No limiting factors that could prevent the conduct of clinical trials to assess S-TPE efficacy in patients with diabetes were identified. S-TPE appears as a promising technique to improve diabetes management. Trial registration number Registration N°: 2019-A00773-54 and NTC: 03956927.
