THU0372 Ultrasonographic scoring of the major salivary glands: is there a relationship with disease activity and functional status of the glands ?

Background Ultrasonography (USG) of major salivary glands (SG-USG)is a non-invasive tool that has been used to evaluate salivary glands in primary and secondary Sjogren’s syndrome (SjS). Objectives We aimed to investigate relation between the ultrasonographic scoring of major salivary glands and systemic disease activity or salivary secretion in patients with primary SjS. Methods Seventy-five SjS patients (F/M:73/2) with the mean age of 52±12 and duration of follow-up period of 58±54 months fulfilling ACR-EULAR classification criteria (2002) were included. Disease activity indexes (Sjogren’s Syndrome Patients Reported Index (ESSPRI), Visual Analogue Scale (VAS), EULAR Sjogren’s Syndrome Disease Activity Index (ESSDAI)] were recorded. Simultaneously, sialometric evaluation of the salivary glands was performed. Major salivary glands (bilateral parotis and submandibular glands) were scored according to two different scoring systems [Hocevar A.(0–48) and Milic VD. (0–12)] and elastography was recorded as well. Results Demographics, clinical characteristics, disease activity indexes and SG-USG scores were summarised in table 1 and table 2. Forty-one (55%) and 45 (60%) patients had the cut-off values of ≥17 (Hocevar) and ≥6 (Milic USG). The patients with the scores of ≥17 (Hocevar) were found to have higher scores of ESSPRI-total (16±6 vs 13±7, p=0,045) and lower sialometry (4,6±4,7 vs 8,4±4,6 ml, p=0,002). Scores of Hocevar and Milic-USG were negatively correlated with sialometry (r=-,430, p=0001 and r=-,430, p=0,001). Hocevar, Milic and elastography-USG scores were shown to be higher in patients with sialometry of ≤1,5 ml (n=7)(28±3 vs 17±10, p=0,010, 8±1 vs 5±3, p=0006 and 9±1 vs 5±2, p=0,028) and anti-Ro positivity(n=24) (24±10 vs 13±8 7±3 vs 4±2, p Conclusions Hocevar scoring system of major salivary glands was found to be related to patient reported activity in SjS. USG scores were associated with reduced saliva secretion and anti-Ro positivity. Severe parotid involvement was shown to be related to anti-RO and La positivity. Evaluation of SG-USG including different scoring systems and elastography might reflect function of the salivary glands. Disclosure of Interest None declared
