Team Ingrid Lundberg

Our team conducts research about myositis, a chronic, rheumatic, autoimmune disorder of unknown cause that affects approximately 1000 people in Sweden.

Myositis - disease mechanisms and effects of treatment

Myositis is a chronic, rheumatic, autoimmune disorder of unknown cause that affects approximately 1 000 people in Sweden. It is characterized by progressive muscle weakness and muscle fatigue particularly affecting thigh, shoulder, and neck muscles. In the most severe forms problems with swallowing may occur. Other organs are frequently involved like the skin, lungs, joints and heart suggesting that this is a systemic inflammatory disease.

Treatment is based on high doses of glucocorticoids in combination with immunosuppressive drugs and with physical exercise. The disease manifestations and prognosis vary between individual patients but overall the myositis disorder is associated with a high degree of morbidity leading to a low health related quality of life and a high mortality. Thus there is a high unmet need of improved treatment, and to achieve this we need to improve the knowledge on underlying pathophysiology and here we want to contribute.

Major research focus

Our research in myositis is focused on disease mechanisms that could explain (1) why you develop myositis, (2) why the muscles become weak and (3) why the lungs are often affected. This will be accomplished through longitudinal studies of patients with myositis and by combining clinical outcome measures and investigations of molecular expression in repeated muscle biopsies and in peripheral blood after different interventions, both pharmacological and exercise.

We also aim to understand immune specificities of myositis in order to find targets for new therapies. One aim is to understand why the muscle becomes a target of the immune reaction leading to muscle weakness and muscle damage. Another aim is to understand the link between the inflammation in muscle and in the lung, which is often affected in patients with myositis.  We also aim to understand the role of exercise to improve muscle health, improve aerobic capacity, reduce inflammation to improve quality of life and prognosis. In addition, our aim is to improve our understanding of patients’ experience of living with myositis, specifically what symptoms patients experience as most debilitating and important to improve and how to assess these symptoms by patient-reported and objective measurement tools.

To accomplish our goals we combine clinical, epidemiological research with molecular research on patient samples. We follow patients at Karolinska University Hospital in a systematic way and collect clinical data and biological samples. We are part of a Swedish Myositis Network, SweMyoNet, and of an international myositis network, where we contribute to the international myositis registry EuroMyositis, in which more than 5 900 patients with myositis have been enrolled.

We are also part of an international collaboration, MYOGEN, on genetic and environmental risk factors for myositis. In addition, we are part of the international myositis collaborations IMACS and OMERACT. In the rheumatology research laboratory at Center for Molecular Medicine, Karolinska Institutet, we analyse the biological samples, muscle biopsies, peripheral blood samples, sera, and plasma. We use immunological tools, such as T cell tetramers and muscle cell cultures to learn about the role of the autoimmune reactions in myositis.
