Pain is frequently the primary variable in symptomatic clinical trials for the evaluation of rheumatological disorders. The protocol of such trials mention a minimum level of pain as an entry criterion [e.g. a level above the Patient Acceptable Symptoms State (PASS)] and the changes in pain as the primary variable. Usually, the results are expressed at a group level as the mean changes in pain. However, the presentation at an individual level and, in particular, the percentage of patients with a Low Disease Activity State at the end of the study seems more clinically relevant. Pain is usually evaluated using a continuous variable such as a 0-100 visual analogue scale. The cut-offs permitting one to define both the entry criterion and the LDAS are not well established. The objective of this study was to evaluate such cut-offs using a patient-derived perspective. ⋯ This study suggests that LDAS and PASS may be distinct concepts. The methodological approach adopted here could be of interest for specifying the minimum level of symptoms at entry in a symptomatic trial (PASS) and also to present results in terms of the percentage of patients in good condition (LDAS) at the end of a trial.

To ascertain the occurrence of osteoporosis and the development of central bone mineral density (BMD) in long-term rheumatoid arthritis (RA) METHODS: BMD of the lumbar spine (L2-L4) and the femoral neck were measured by dual-energy X-ray absorptiometry in a cohort of 59 patients (49 women and 10 men) with rheumatoid factor-positive RA followed up for 20 years. BMD measurements were obtained at the 15- and 20-year follow-up visits. ⋯ We conclude that in long-term RA central bone densities seemed to be only moderately decreased after 15 years from eruption of RA. No essential change in central BMD was found after the consecutive 5 years.
