- OBJECTIVE: To assess the potential of metastasin S100A4 as a biological marker in patients with RA. METHODS: A total of 87 unselected patients with established RA (disease duration 2-44 years) and treated with MTX and infliximab at a single rheumatology centre were included in a cross-sectional study. Radiographs of hands and feet were taken prior to infliximab treatment and at inclusion (time interval 48±27 months) and scored for the radiographic damage. S100A4 levels were analysed in relation to radiographic damage, clinical disease activity (DAS-28), inflammation (IL-6, CRP, ESR), bone and cartilage markers [MMP-3, COMP, C-telopeptide of type I collagen (CTX-I)] and proto-oncogenes [survivin, insulin-like growth factor 1 (IGF-1), Flt3 ligand]. RESULTS: High levels of S100A4 were associated with severe radiographic damage (OR=3.40, P=0.025), non-response to infliximab (OR=4.63, P=0.003), presence of antibodies to infliximab (OR=6.24, P=0.003) and high levels of Flt3 ligand (OR=2.73, P=0.04). Regression analysis showed that high S100A4 was predictive for radiographic progression during infliximab treatment [positive predictive value (PPV) 0.68, P=0.05]. Low levels of S100A4 were associated with response to infliximab (OR=2.67, P=0.049), clinical remission (OR=4.01, P=0.0047) and negative RF (OR=9.22, P=0.0047). S100A4 correlated with survivin (r=0.71, P>0.0001). CONCLUSION: S100A4 levels are increased in proportion to radiographic damage and its further progression in RA patients. High S100A4 levels were associated with a poor clinical response to infliximab and high rate of anti-infliximab antibodies. The finding of a correlation between S100A4 and survivin and Flt3 ligand suggests that these proteins may represent a new cluster of biomarkers predicting radiographic progression and poor treatment response in RA patients.

- Purpose: To explore how women experience living with long-term pregnancy-related pelvic girdle pain.Materials and methods: Nine women with persistent pregnancy-related pelvic girdle pain of 2–13 years were recruited by means of purposive sampling from long-term follow-up studies. The women were 28–42 years of age and had given birth to 2–3 children. Audio-taped in-depth interview with open-ended questions were used with the guiding question 'How do you experience living with pregnancy-related pelvic girdle pain?'. The Empirical Phenomenological Psychological method was chosen for analysis.Results: The pregnancy-related pelvic girdle pain syndrome has a profound impact on everyday life for many years after pregnancy. Three constituents were identified as central to the experience of living with pregnancy-related pelvic girdle pain: (1) the importance of the body for identity, (2) the understanding of pain, and (3) stages of change. The manner in which the women experienced their pain was interpreted in terms of two typologies: the ongoing struggle against the pain, and adaptation and acceptance.Conclusion: The participants’ narratives highlighted that the pain led to severe functional limitations that threatened their capability to perform meaningful daily activities, and interfered with their sense of identity. It appears essential to meet with each patient individually and to manage long-term pregnancy-related pelvic girdle pain as a pain syndrome.IMPLICATIONS FOR REHABILITATIONChronic pregnancy-related pelvic girdle painPregnancy-related pelvic girdle pain impairs women’s capacity to perform meaningful activities of daily life for many years after pregnancy.The participants’ narratives highlighted that the pain interfered with their sense of identity.It appears essential to meet with each patient individually and to manage long-term pregnancy-related pelvic girdle pain as a pain syndrome.

- Antibody-based proteomics provides a powerful approach for the functional study of the human proteome involving the systematic generation of protein-specific affinity reagents. We used this strategy to construct a comprehensive, antibody-based protein atlas for expression and localization profiles in 48 normal human tissues and 20 different cancers. Here we report a new publicly available database containing, in the first version, similar to 400,000 high resolution images corresponding to more than 700 antibodies toward human proteins. Each image has been annotated by a certified pathologist to provide a knowledge base for functional studies and to allow queries about protein profiles in normal and disease tissues. Our results suggest it should be possible to extend this analysis to the majority of all human proteins thus providing a valuable tool for medical and biological research.
