Abstract

Background Non-infectious aortitis is an inflammation of aortic wall which may be isolated or associated with a cluster of diseases.

Objectives Our aim was to compare the clinical and laboratory findings of patients with isolated aortitis and patients with aortitis secondary to other underlying conditions.

Methods Retrospective study of 93 patients with non-infectious aortitis diagnosed by PET/CT scan from a referral center from January 2010 to December 2016. We have considered two groups: group a) isolated aortitis; and group b) secondary aortitis. Distributions of categorical variables were compared by the Pearson Chi2 or Fisher exact test. Quantitative variables were analyzing using the Student t test or Mann-Whitney U test as appropriate.

Results Ninety-three patients were diagnosed with non-infectious aortitis. One patient was excluded due to missing data. Group a) was composed by 54 patients (34 women/ 20 men) with a mean age of 67±11 years; group b) comprised 38 patients (28 women/ 10 men) with a mean age of 68±11 years. In this group, the underlying conditions we found were: giant cell arteritis (n=24), Takayasu arteritis (n=3), spondiloarthropathy (n=3), Sjögren's syndrome (n=3), ulcerative colitis (n=2), sarcoidosis (n=1), rheumatoid arthritis (n=1), polyarteritis nodosa (n=1). The comparative study between both groups is shown in the TABLE. Only inflammatory low back pain and polymyalgic syndrome yielded statistical signification.

Conclusions In this study, we observed that both the presence of inflammatory low back pain and polymyalgic syndrome might have clinical relevance in the clinical suspicion of primary aortitis. However, larger studies are needed to corroborate these findings.
