Brief summary
In a research project, investigators want to study the course of the disease of axial spondylitis: the causes of disease onset, prognosis, and treatment effects. The goal is to improve treatment and in the long run also prevention of the disease. The project has a focus on the body's own substance prostaglandin, and its proinflammatory role in spondylitis, but also other substances may be analyzed in blood and urine samples. The purpose of the research project is include newly diagnosed treatment-naive patients with axial spondyloarthritis, to follow them after 1 and 2 years after treatment start, to collect clinical data, questionnaires, blood and urinsamples to find blood or urine markers that can be used for precision therapy of axial spondylitis.
Detailed description
The EISPA study is an epidemiological and translational study in axial spondylitis patients who are included in the Swedish Rheumatology Quality Register (SRQ). EISPA aims to include consecutive newly diagnosed axial spondylitis patients. Despite the fact that the disease is relatively common, it takes on average 10 years after start of symptoms for patients be diagnosed with axial spondylitis. Axial spondylitis diagnosis is based on clinical findings rather than diagnostic tests, which reflects lack of knowledge about what causes the disease. At present, our possibilities to predict the course of the disease (and thereby individualize the care of the patient) are limited. Current treatment decreases inflammation rather than treating the cause of the disease. The first treatment step of axial spondylitis is with non-steroidal anti-inflammatory drugs or COX inhibitors, which usually have insufficient effect against inflammatory pain and stiffness. In addition, these drugs are associated with side effects, such as gastrointestinal and cardiovascular side effects. Axial spondylitis is a multifactorial disease where the arachidonic acid cascade, an increased prostaglandin production and release may play a major role. With this there is a clear potential to develop new specific drugs to slow down the prostaglandin cascade in patients with axial spondylitis.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Prostaglandin levels | 2 years | Investigators measure prostaglandin levels in treatment-naïve patients at baseline, and then after therapy start after 1 and 2 years. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Questionnaires | 2 years | Investigators collect data on modifiable environmental factors and lifestyle that may contribute to the onset of the disease. |
| Clinical data | 2 years | Investigators collect clinical data as entered in the Swedish Rheumatology Quality Register (SRQ) plus the ASAS-health index (0-17, with a lower score indicating a better health status), such as inflammatory markers ESR (mm/hour)/CRP (mg/l), and other variables in the ASAS core outcome set for all trials as defined by ASAS-Omeract. |
