Inflammatory low back pain: high negative predictive value of contrast-enhanced color Doppler ultrasound in the detection of inflamed sacroiliac joints.

OBJECTIVE: To determine the value of microbubble contrast agents for color Doppler ultrasound (CDUS) compared with magnetic resonance imaging (MRI) in the detection of active sacroiliitis. METHODS: An observational case-control study of 103 consecutive patients (206 sacroiliac [SI] joints) with inflammatory low back pain according to the Calin criteria and 30 controls (60 SI joints) without low back pain was conducted at the University Hospital of Innsbruck. All patients and controls underwent unenhanced and contrast-enhanced CDUS and MRI of the SI joints. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of unenhanced and contrast-enhanced CDUS were evaluated. RESULTS: Forty-three patients (41%) with 70 of 206 SI joints (34%) and none of the controls nor the 60 control SI joints demonstrated active sacroiliitis on MRI. Unenhanced CDUS showed a sensitivity of 17%, a specificity of 96%, a PPV of 65%, and an NPV of 72%; contrast-enhanced CDUS showed a sensitivity of 94%, a specificity of 86%, a PPV of 78%, and an NPV of 97%. Detection of vascularity in the SI joint was increased by contrast administration (P < 0.0001). Clustered receiver operating curve analysis demonstrated that enhanced CDUS (A(z) = 0.89) was significantly better than unenhanced CDUS (A(z) = 0.61) for the diagnosis of active sacroiliitis verified by MRI (P < 0.0001; 2-sided test). CONCLUSION: Microbubble contrast-enhanced CDUS is a sensitive technique with a high NPV for detection of active sacroiliitis compared with MRI.

Application of the OMERACT filter to scoring methods for magnetic resonance imaging of the sacroiliac joints and the spine. Recommendations for a research agenda at OMERACT 7.

Magnetic resolution imaging (MRI) is a promising tool in the assessment of inflammation and structural damage in clinical trials in ankylosing spondylitis (AS). The ASAS/OMERACT MRI in AS working group, a collaborative initiative of rheumatologists and musculoskeletal radiologists with a special interest in this field, collected data on all available scoring methods for both sacroiliac (SI) joints and spine, and tested them with respect to the OMERACT filter. These data were presented together with the technical specifications of all methods at the OMERACT 7 conference. In addition, the results of 2 separate experiments on the inter-reader reliability of scoring methods to assess activity in SI joints, and on the comparison of STIR sequence versus T1 post-gadolinium (Gd) sequence for the spine, were presented. Thereafter, 8 groups discussed these data and proposed a research agenda, each on a different topic. This information was reported back to all participants and a prioritized research agenda was compiled by voting. Research on scoring methods for assessing disease activity, in both the spine and SI joints, was considered most important. Research on assessing structural damage was considered less important. The specific process and results of this initiative are discussed.

The reliability of selected pain provocation tests for sacroiliac joint pathology.

OBJECTIVE: To assess the inter-rater reliability of seven pain provocation tests for pain of sacroiliac origin in low back pain patients. SUMMARY OF BACKGROUND DATA: Previous studies on the reliability of such tests have produced inconclusive and conflicting results. METHODS: Fifty-one patients with low back pain, with or without radiation into the lower limb, were assessed by one examiner and another drawn from a pool of five. Percent agreement and the Kappa statistic were used to evaluate the reliability of the seven tests. RESULTS: Percent agreement and the Kappa statistic ranged in value from 78% and 0.52 (P < 0.001) to 94% and 0.88 (P < 0.001), respectively, when results for all examiner pairs were pooled. However, two tests demonstrated only marginal reliability when performed by one pair of assessors that examined 43% of the patients. CONCLUSIONS: Five of seven tests employed in this study were reliable, the other two were potentially reliable. These tests may be used to detect a sacroiliac source of low back pain, although sensitivity and specificity studies are needed to determine their diagnostic power.
