OBJECTIVE: To establish a point-scoring diagnostic system for Sjögren's syndrome
(SS) based on quantified SPECT imaging of salivary gland, and evaluate its
feasibility and performance compared with 2002 AECG criteria and 2012 ACR
criteria. METHODS: 213 patients with suspected SS enrolled in this study. The
related clinical data of all patients were collected. All patients were evaluated
and grouped on a clinical basis and posttreatment follow-up by rheumatology
specialists as the unified standard (SS group with 149 cases and nSS group with
64 cases). From SPECT imaging of salivary gland, Tmax, UImax, Ts and EFs were
derived for bilateral parotid and submandibular glands, and compared between the
groups. A point-scoring diagnostic system for SS was established based on the
quantified SPECT imaging of salivary gland. We estimated the sensitivity,
specificity, positive predictive value (PPV), negative predictive value (NPV) and
accuracy for the new diagnostic system, compared with 2002 AECG criteria and 2012
ACR criteria. RESULTS: When 7.0 was used as the cut-off point, the sensitivity,
specificity, PPV, NPV and accuracy for the new point-scoring system in diagnosing
SS were 89.93% (134/149), 93.75% (60/64), 97.10% (134/138), 80.00% (60/75) and
91.08% (194/213), respectively. The new point-scoring diagnostic system based on
quantified SPECT imaging of salivary gland keeps the specificity comparatively to
2002 AECG criteria and 2012 ACR criteria, but improves the sensitivity
significantly (P<0.01). CONCLUSION: The new point-scoring diagnostic system for
SS based on quantified SPECT imaging of salivary gland may be superior to 2002
AECG criteria and 2012 ACR criteria, with higher sensitivity and similar
specificity in the diagnosis of SS. Additionally, it also has good feasibility in
the clinical settings.
