Jon Lampa Team

Jon Lampa’s team researches rheumatic pain. Despite new
drugs and new means of retarding the course of the disease, around one fifth
of patients suffer persistent pain that is difficult to treat and that
profoundly impairs their quality of life. Lampa studies what causes this
pain, the mechanisms behind it and how it could be prognosed and prevented.
His research can also contribute to a more general understanding of chronic
pain, such as that experienced in fibromyalgia.
Lampa’s research involves the analysis of blood and cerebrospinal fluid as
well as functional MRI. He heads up a Nordic-European project on pain and
fatigue in early rheumatoid arthritis (RA).
Lampa’s research team has recently identified in patients with RA
biomarkers for an elevated risk of suffering chronic pain.
