Neurorheumatology and Pain Research – Research group Jon Lampa

Rheumatic pain is an unmet need for many patients. Our research group investigates rheumatic pain as a distinct and complex phenomenon that cannot be fully explained by joint inflammation alone. This work is grounded in both clinical and translational analyses to map pain-related pathways in the immune system and the central nervous system. Moreover, we investigate the interplay between fatigue, pain, and disease activity as well as novel bioelectronic therapies for immune suppression.

Our research focus

The Neurorheumatology and pain research group investigates rheumatic pain as a distinct and complex phenomenon that cannot be fully explained by joint inflammation alone. 

Despite major advances in antirheumatic and biologic therapies, around one fifth of patients continue to experience persistent, difficult‑to‑treat pain, which significantly reduces quality of life. Our research aim to uncover:

  • What causes persistent pain in diseases such as rheumatoid arthritis (RA)
  • Which biological mechanisms maintain pain even after inflammation is treated
  • How chronic pain can be predicted, prevented, and better managed

This work is grounded in the analysis of blood, cerebrospinal fluid, and functional MRI, allowing the team to map pain‑related pathways in both the immune system and the central nervous system. Immune mediators that amplify pain signaling. Moreover, we investigate immune mediators that amplify pain signaling and the interplay between fatigue, pain, and disease activity.

Clinical relevance and societal impact

Chronic pain and fatigue remain among the most disabling symptoms for people with autoimmune diseases. Even when inflammation is well treated, pain can continue to impair work ability, daily functioning, and quality of life.

Our research addresses this gap by:

  • Improving understanding of pain mechanisms
  • Supporting development of more effective pain treatments
  • Reducing long‑term disability and healthcare burden
  • Enhancing patient‑centered outcomes in rheumatology

The TRAVAGA study

The TRAVAGA study is a placebo‑controlled clinical trial investigating whether non‑invasive auricular vagus nerve stimulation (taVNS) can reduce chronic inflammation and pain in people with difficult‑to‑treat rheumatoid arthritis (RA). It is conducted in collaboration with Karolinska Institutet and six rheumatology clinics in Sweden. ClinicalTrials.gov ID: NCT06779123.
