Abstract
in English, Portuguese

Context and objective: Accelerated atherosclerosis has become a major problem in rheumatic inflammatory disease. The aim here was to analyze carotid intima-media thickness (IMT) in spondyloarthritis (SpA) patients and correlate this with clinical parameters and inflammatory markers.

Design and setting: Cross-sectional analytical study at Rheumatology Outpatient Clinic, Evangelical University Hospital, Curitiba.

Methods: IMTs (measured using Doppler ultrasonography) of 36 SpA patients were compared with controls. The IMT in SpA patients was associated with inflammatory markers, like erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI); and with clinical parameters, like axial or peripheral involvement, dactylitis, HLA B27, uveitis occurrence, Bath Ankylosing Spondylitis Functional Index (BASFI) and lipid profile.

Results: The mean IMT in SpA patients was 0.72 ± 0.21 mm; in controls, 0.57 ± 0.13 mm (P = 0.0007). There were no associations with ESR, CRP, BASDAI or clinical data. In univariate analysis, greater IMT was seen in patients with longer disease duration (P = 0.014; Pearson R = 0.40; 95% confidence interval, CI = 0.06 to 0.65); higher triglycerides (P = 0.02; Spearman R = 0.37; 95% CI = 0.03 to 0.64); and older age (P = 0.0014; Pearson R 0.51; 95% CI = 0.21 to 0.72).

Conclusion: SpA patients have a higher degree of subclinical atherosclerosis than in controls, thus supporting clinical evidence of increased cardiovascular risk in rheumatic patients.

CONTEXTO E OBJETIVO:: A aterogênese acelerada tem se tornado um grande problema nas doenças reumáticas inflamatórias. O objetivo foi analisar a espessura da camada íntima-média (ECIM) da carótida em pacientes com espondiloartrite (ES) e relacioná-la com parâmetros clínicos e marcadores inflamatórios. TIPO DE ESTUDO E LOCAL: Estudo transversal analítico no Ambulatório de Reumatologia do Hospital Universitário Evangélico de Curitiba.

MÉTODOS:: A ECIM (medida por Doppler) de 36 pacientes com ES foi comparada com controles. A ECIM de pacientes com ES foi associada com marcadores inflamatórios, como velocidade de hemossedimentação (VHS), proteína C-reativa (PCR), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), e com parâmetros clínicos, como envolvimento axial e periférico, dactilite, HLA B27, ocorrência de uveíte, Bath Ankylosing Spondylitis Functional Index (BASFI) e perfil lipídico.

RESULTADOS:: A ECIM média em pacientes com ES foi de 0,72 ± 0,21 mm, enquanto nos controles foi de 0,57 ± 0,13 mm (P = 0,0007). Não se encontrou associação com VHS, PCR, BASDAI e dados clínicos. Em análise univariada, maior ECIM foi encontrado nos indivíduos com maior duração de doença (P = 0,014; R Pearson = 0,40; 95% intervalo de confiança, IC = 0,06 to 0,65), aumento nos triglicerídeos (P = 0,02; R Spearman = 0,37; 95% IC = 0,03 to 0,64) e maior idade (P = 0,0014; R Pearson 0,51; 95% IC = 0,21 to 0,72).

CONCLUSÃO:: Pacientes com ES têm maior grau de aterosclerose subclínica do que controles, dando suporte às evidências clínicas de aumento de risco cardiovascular em pacientes com doenças reumáticas.
