Numerous clinical trials have established that various biologic and oral small-molecule therapies are efficacious in patients with psoriasis. However, as there are limited head-to-head trials, healthcare providers may compare results across multiple trials when providing treatment recommendations. Direct comparisons among agents are challenging because psoriasis trials differ in terms of study design, patient population, and data analysis methodologies.

Introduction: Multiple Sclerosis (MS) is a complex auto-inflammatory disease affecting the brain and spinal cord, which results in axonal de-myelination and symptoms including fatigue, pain, and difficulties with vision and mobility. The involvement of the immune system in the pathology of MS is well established, particularly the adaptive T cell response, and there has been a particular focus on the IL-17-producing subset of Th17 cells and their role in driving disease. However, the importance of innate immune cells has not been so well characterised.

Background: Contingency management (CM), an incentive-based intervention to encourage target behaviors, effectively promotes medication adherence. However, efforts to extend CM to HIV pre-exposure prophylaxis (PrEP) have been lacking. As part of a randomized clinical trial to promote HIV Prevention among people who inject drugs (PWID), we examined the readiness of staff in community-based organizations serving PWID to implement CM for PrEP uptake and adherence in this population.

Article Synopsis
  • Cystic fibrosis (CF) is characterized by heightened neutrophil presence in the airways and inefficient apoptosis, prompting the investigation of whether NETosis (a form of neutrophil clearance) plays a significant role in CF lung disease.
  • In a study involving 45 CF and 15 healthy participants, researchers found higher neutrophil counts and abnormal morphology in CF sputum, alongside elevated levels of inflammatory mediators and NETs, indicating a strong link between NETs and airway inflammation.
  • Treatment with DNase reduced sputum NET levels and mitigated the pro-inflammatory effects of NETs in co-culture experiments, highlighting its potential as an anti-inflammatory therapy in CF management.

Background: The intestinal barrier encompasses physical and immunological components that act to compartmentalize luminal contents, such as bacteria and endotoxins, from the host. It has been proposed that an age-related decline of intestinal barrier function may allow for the passage of luminal contents into the bloodstream, triggering a low-grade systemic inflammation termed inflamm-aging. Although there is mounting evidence to support this hypothesis in model species, it is unclear if this phenomenon occurs in humans.
