To investigate the association of cigarette smoking with clinical expression, disease activity and severity in a cohort of Greek patients with early rheumatoid arthritis (RA). ⋯ In our early RA patients, cigarette smoking was associated with increased disease activity, and severity, independently of several other possible confounders and despite the early disease treatment.

Pooled indices of several measures have been developed to assess and monitor patients with rheumatoid arthritis in clinical trials and clinical care, as no single measure can serve as a "gold standard" in all individual patients. Early indices of disease activity include the Steinbrocker "therapeutic scorecard in rheumatoid arthritis," the Lansbury Index, and Paulus criteria. ⋯ The ACR Core Data Set includes 7 measures--swollen joint count, tender joint count, patient assessment of global status, an acute phase reactant [erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP)], health professional assessment of global status, physical function, and pain; the first four of these measures are included on the DAS. Improvement criteria for the ACR Core Data Set are based on improvement of at least 20% in both tender and swollen joint counts, and three of the five additional measures (ACR 20), and corresponding "ACR 50," and "ACR 70." A pooled index which includes only the three patient self-report questionnaire measures from the Core Data Set, physical function, pain, and patient assessment of global status performs as well as ACR 20 or DAS to discriminate between efficacy of active versus placebo treatment in a clinical trial.

Viscosupplementation with hyaluronic acid (HA) or its derivatives for the symptomatic relief of osteoarthritis (OA) of the hip joint has never been studied in placebo-controlled, double-blinded trials and conflicting results have been obtained from the published open trials. The aim of this study was to review the literature on viscosupplementation as a symptomatic treatment of hip OA. ⋯ To date, in the absence of placebo-controlled studies, the efficacy of IA injections of HA or its derivatives in the symptomatic treatment of hip OA cannot be determined conclusively. Nevertheless the published data suggest that viscosupplementation may be effective. Double-blind, controlled studies are required to confirm these data, before viscosupplementation should be included into the treatment paradigm for patients with hip osteoarthritis.

Disability has been identified as a core outcome measure in rheumatoid arthritis (RA). The aim of this study was to test the Recent-Onset Arthritis Disability (ROAD) questionnaire for validity, reliability and responsiveness in Italian patients with early RA. ⋯ Our data suggest that the ROAD index is a reliable, valid and responsive tool for measuring physical functioning in patients with early RA, and is suitable for use in clinical trials and daily clinical practice. Its generalizability and utility for assessing aggressive treatment and functional outcomes must now be evaluated in broader settings.
