New tools for classification and monitoring of autoimmune diseases

Rheumatologists see patients with a range of autoimmune diseases. Phenotyping these diseases for diagnosis, prognosis and selection of therapies is an ever increasing problem. Advances in multiplexed assay technology at the gene, protein, and cellular level have enabled the identification of 'actionable biomarkers'; that is, biological metrics that can inform clinical practice. Not only will such biomarkers yield insight into the development, remission, and exacerbation of a disease, they will undoubtedly improve diagnostic sensitivity and accuracy of classification, and ultimately guide treatment. This Review provides an introduction to these powerful technologies that could promote the identification of actionable biomarkers, including mass cytometry, protein arrays, and immunoglobulin and T-cell receptor high-throughput sequencing. In our opinion, these technologies should become part of routine clinical practice for the management of autoimmune diseases. The use of analytical tools to deconvolve the data obtained from use of these technologies is also presented here. These analyses are revealing a more comprehensive and interconnected view of the immune system than ever before and should have an important role in directing future treatment approaches for autoimmune diseases.     

Building an online community to promote communication and collaborative learning between health professionals and young people who self‐harm: an exploratory study

Background

Online communities are known to break down barriers between supposed experts and non‐experts and to promote collaborative learning and ‘radical trust’ among members. Young people who self‐harm report difficulties in communicating with health professionals, and vice versa.

Aim

We sought to bring these two groups together online to see how well they could communicate with each other about self‐harm and its management, and whether they could agree on what constituted safe and relevant advice.

Methods

We allocated 77 young people aged 16–25 with experience of self‐harm and 18 recently/nearly qualified professionals in relevant health‐care disciplines to three separate Internet discussion forums. The forums contained different proportions of professionals to young people (none; 25%; 50% respectively) to allow us to observe the effect of the professionals on online interaction.

Results

The young people were keen to share their lived experience of self‐harm and its management with health professionals. They engaged in lively discussion and supported one another during emotional crises. Despite registering to take part, health professionals did not actively participate in the forums. Reported barriers included lack of confidence and concerns relating to workload, private–professional boundaries, role clarity, duty of care and accountability. In their absence, the young people built a vibrant lay community, supported by site moderators.

Conclusions

Health professionals may not yet be ready to engage with young people who self‐harm and to exchange knowledge and experience in an anonymous online setting. Further work is needed to understand and overcome their insecurities.
