The comparative responsiveness of Hospital Universitario Princesa Index and other composite indices for assessing rheumatoid arthritis activity

Objective To evaluate the responsiveness in terms of correlation of the Hospital Universitario La Princesa Index (HUPI) comparatively to the traditional composite indices used to assess disease activity in rheumatoid arthritis (RA), and to compare the performance of HUPI-based response criteria with that of the EULAR response criteria. Methods Secondary data analysis from the following studies: ACT-RAY (clinical trial), PROAR (early RA cohort) and EMECAR (pre-biologic era long term RA cohort). Responsiveness was evaluated by: 1) comparing change from baseline (Delta) of HUPI with Delta in other scores by calculating correlation coefficients; 2) calculating standardised effect sizes. The accuracy of response by HUPI and by EULAR criteria was analyzed using linear regressions in which the dependent variable was change in global assessment by physician (Delta GDA-Phy). Results Delta HUPI correlation with change in all other indices ranged from 0.387 to 0.791); HUPI's standardized effect size was larger than those from the other indices in each database used. In ACT-RAY, depending on visit, between 65 and 80% of patients were equally classified by HUPI and EULAR response criteria. However, HUPI criteria were slightly more stringent, with higher percentage of patients classified as non-responder, especially at early visits. HUPI response criteria showed a slightly higher accuracy than EULAR response criteria when using Delta GDA-Phy as gold standard. Conclusion HUPI shows good responsiveness in terms of correlation in each studied scenario (clinical trial, early RA cohort, and established RA cohort). Response criteria by HUPI seem more stringent than EULAR''s

Psoriasis : State of the art 2013 Part II :Therapeutics

The treatment of psoriasis is mainly based on anti-inflammatory and/or anti-hyperproliferative agents. The topical steroids appeared in the fifties and were the first therapeutic breakthrough for psoriasis, followed by methotrexate and phototherapy in the sixties, photochemotherapy (PUVA) in the seventies and acitretin and cyclosporine in the eighties. The targeted biologic therapies represent a whole new era of therapeutic possibilities with a highly beneficial safety record. The choice of treatment depends on a large series of factors, including the type and extend of the psoriasis, the patient's preferences, co-medications, comorbidities and drug tolerance. This overview presents the currently available topical and systemic agents for treating psoriasis, including topical corticosteroids, vitamin D derivatives, UV-light based therapies, methotrexate, cyclosporine, acitretin, and the biologic agents such as the TNF antagonists etanercept, adalimumab and infliximab, as well as the anti-p40 IL12/23 agent ustekinumab. Newer, very promising, agents aiming the Th17 pathway are under development for psoriasis
