Takayasu arteritis in southern Sweden

Area of Science:

• Rheumatology
• Epidemiology
• Vascular Medicine

Background:

• Takayasu arteritis (TA) is a rare, chronic inflammatory disease affecting large arteries.
• Understanding the epidemiology and clinical features of TA is crucial for early diagnosis and management.

Purpose of the Study:

• To investigate the epidemiology and clinical characteristics of Takayasu arteritis (TA) in southern Sweden.
• To determine the incidence and prevalence of TA in a defined Swedish population.

Main Methods:

• Retrospective study of patients diagnosed with TA between 1997 and 2011 in southern Sweden.
• Inclusion criteria: fulfillment of the 1990 American College of Rheumatology classification criteria for TA.
• Data collection from hospital and private rheumatology clinic registries.

Main Results:

• Thirteen female patients with TA were identified, with a median age of 23 years at diagnosis.
• The annual incidence rate was 0.7/million inhabitants (1.5/million among women).
• Point prevalence was 13.2/million inhabitants (26.2/million among women); subclavian arteries were most commonly affected, and all patients experienced organ damage.

Conclusions:

• The incidence of TA in Sweden is comparable to other European studies.
• The prevalence of TA in this region is higher than previously reported.
• TA has a good prognosis, but a high rate of organ damage necessitates ongoing monitoring.
