Half of Takayasu's Arteritis Relapse

A French retrospective study of 318 Takayasu's arteritis (TA) patients shows that 50% of patients will relapse and experience a vascular complication ≤10 years from diagnosis. 

A multicenter study examined 318 TA patients meeting both ACR and and Ishikawa criteria to assess event-free survival, relapse-free survival, vascular complications and risk factors for vascular complications.  At diagnosis, TA primarily affects younger (mean age 36 [25–47] years) women (86.8%).

With 6.1 years of follow-up, relapses were observed in 43%, vascular complications in 38%, and death in 5%.

Progressive disease course (P=0.018) and carotidynia (P=0.036) were independently associated with event-free survival.

Outomes observed:

Conclusions: This nationwide study shows that 50% of patients with TA will relapse and experience a vascular complication ≤10 years from diagnosis.

Are ANA Tests Unreliable?

Pisetsky and colleagues have reported in the Annals of Rheumatic Disease that ANA tests done on established SLE patients may yield surprisingly disparate results.

While ANA negative lupus was a problem of old assays and the loss of ANA positivity may be seen with chronicity or age, most rheumatologists believe that ANA positivity is an absolute requirement for the diagnosis of systemic lupus erythematosus.
