BACKGROUNDWe evaluated the safety and viral rebound, after analytical treatment interruption (ATI), of vedolizumab and ART in recent HIV-1 infection. We used this model to analyze the effect of α4β7 on the HIV-1 reservoir size.METHODSParticipants started ART with monthly vedolizumab infusions, and ATI was performed at week 24.

The treatment of inflammatory bowel disease has undergone a significant transformation following the introduction of biologic drugs. Thanks to these drugs, treatment goals have evolved from clinical response and remission to more ambitious objectives, such as endoscopic or radiologic remission. However, even though biologics are highly effective, a significant percentage of patients will not achieve an initial response or may lose it over time.

Article Synopsis
  • * A total of 340 pediatric patients treated with infliximab or adalimumab were genotyped for 9 specific genetic variants, revealing that certain variants are linked to poorer long-term treatment outcomes.
  • * Identifying these genetic markers could help tailor anti-TNF therapy for children, allowing healthcare providers to better predict which patients are likely to benefit in the long run, pending further validation.

Article Synopsis
  • * Conducted at three hospitals, the research involved 45 adults receiving vedolizumab, with serum concentrations measured at weeks 6 and 14, and responses evaluated at multiple points up to one year.
  • * Results indicated that higher serum concentrations at week 6 correlated with better early and long-term responses to treatment, suggesting potential benefits of early monitoring for improving patient outcomes.

Background: Posaconazole is an antifungal agent extensively used as a prophylaxis for invasive fungal infections (IFIs) in allogeneic stem cell transplant (SCT) recipients. Low posaconazole concentrations have been associated with reduced clinical response. The aim of this study was to develop a population pharmacokinetic (popPK) model of a posaconazole tablet formulation in allogeneic SCT adult recipients for supporting model-informed precision dosing (MIPD).

Background: Therapeutic drug monitoring (TDM) of voriconazole is recommended for personalizing doses. The objective of this study was to compare the enzyme immunoassay developed by ARK Diagnostics Inc. for the quantification of voriconazole adapted to the Architect C4000 autoanalyzer (Abbott®) with ultra-performance liquid chromatography using ultraviolet detector (UPLC-UV) method.

Objective: Switching patients from the originator infliximab to a biosimilar is a measure to expand access to treatments and counteract its negative impact on healthcare budgets. However, industry-independent long-term studies on the effect of switching in real life to support the lack of switch-related problems in inflammatory bowel disease (IBD) patients are sparse, as are studies addressing infliximab pharmacokinetic behaviour. The objectives were to investigate the effectiveness and the pharmacokinetics of CT-P13 after switching from originator infliximab in a real-world population of IBD patients with a follow-up of 2 years.

Aims: Identifying DNA variants associated with trough serum anti-tumour necrosis factor (TNF) levels could predict response to treatment in inflammatory bowel disease (IBD). To date, no specific studies have been performed in children. The aim of this study was to identify genetic variants associated with trough serum anti-TNF levels and whether these variants are differential markers for infliximab and adalimumab.

Inflammatory bowel disease (IBD) is commonly treated with adalimumab. The main objective of the study was to develop a population pharmacokinetic model of adalimumab in IBD patients evaluating the potential biomarkers of disease activity and other factors and its implications in adalimumab dosing. A prospective observational study was performed in adult patients diagnosed with Crohn's disease and ulcerative colitis treated with adalimumab and following a proactive therapeutic drug monitoring of serum concentrations.

Aims: Therapeutic drug monitoring (TDM) of trough serum infliximab concentrations has been mainly used in case of loss of response in patients with inflammatory bowel disease (IBD). The aim of this study was to evaluate the effectiveness and safety of a multidisciplinary early proactive TDM (mep-TDM) programme for dose adjustment.

Methods: A 3-year prospective study was conducted based on a sample of 81 patients who started treatment and were subsequently subjected to mep-TDM with the first control at week 14.

Background: Accidental falls have a significant economic and human impact. The use of certain drugs is one of the modifiable risk factors associated with these events.

Objective: The aim of this study was to determine the prevalence of use and to explore changes in treatment with fall-related drugs in patients over 65 years of age admitted as a result of a fall-related fracture.
