SAT0550 Predictive Value of Power Doppler Ultrasonography (PDUS) for The Diagnosis of Rheumatoid Arthritis in Patients with Basal Negative Acute Phase Reactants

BackgroundThe presence of acute phase reactants high can assist in the diagnosis and classification of patients with rheumatoid arthritis, although on occasions in early arthritis may be within the range of normality.ObjectivesThe objective was to establish whether the presence of basal Doppler signal in patients with negative reactants may be helpful in order to establish the risk of final diagnosis of rheumatoid arthritis a year, following ACR criteria 1987MethodsWe studied the presence of Power Doppler (PD) signal on 28 joints (shoulders, elbows, wrists, MCPs, knees) and 44 joints (28 joints and in addition hips, Tarsus, ankles and MTPs), with a mid-range equipment GE L5, in patients with suspected early arthritis in which the ESR was normal according to two different criteria or the CRP was negative. The patients had at least one of the following inclusion criteria: a) Swelling in 2 or more joints b) pain in MCPs, MTPs and/or the wrists c) morning stiffness of more than 30 minutes (*Criteria SERAP Study), with
