Do mRI and serum biomarkers correlate with radiographic features in painful hand osteoarthritis? Context: To explore the relationship between clinical findings, biologic biomarkers, conventional radiography and MRI in patients with painful hand OA. The following patient baseline data from the DORA study (evaluating anti-TNF-α agents against painful hand OA) were used: clinical assessment (pain, swelling, stiffness and function: Dreiser functional hand index [FIHOA] and Cochin hand functional scale [CHFS]); measurement of biomarkers (cartilage oligomeric matrix protein (COMP), type IIA collagen N-propeptid (PIINP), hyaluronic acid (HA), ultrasensitive C-reactive protein (usCRP), tumour necrosis factor (TNF), interleukin (IL)-6, IL-1β and urinary CTXII); radiological staging (Verbruggen, Kallman, Kellgren-Lawrence); anatomical evaluation by contrast-enhanced MRI of proximal and distal interphalangeal joints of dominant hand. Associations between clinical, biomarker and imaging findings were assessed using the Spearman correlation coefficient and test. 18 patients were recruited, and 144 joints studied. A correlation was found between clinical features (pain, FIHOA, CHFS) and the Verbruggen score (respectively: p=0.05, r=0.47; p=0.05, r=0.48; p=0.05, r=0.48). Serum IL-1 level was strongly associated with loss of function (FIHOA: p=0.02, r=-0.73; CHFS: p=0.01, r=-0.76) and radiological erosions (p=0.03, r=0.7) as with urinary CTX2. A significant association was found between MRI osteophytes and usCRP (p=0.0026). MRI and radiological features were significantly correlated except for synovitis and bone marrow lesions.

MRI synovitis was not correlated with radiological scores, clinical or biologic markers of inflammation. There was a strong correlation between other MRI features and radiological scores. Serum IL-1 level was associated with structural damage and function. Final Decision: yes
