These results are consistent with the recently published findings generated by different methods and support the use of a "much better" improvement on the pain relief as a clinically important outcome. A further confirmation in other patient populations and different chronic pain syndromes will be needed.
Older adults with OA of the lower extremities undergo a significant impact on multiple dimensions of HRQOL, compared with healthy controls. The use of a generic measure of HRQOL such as the SF-36, in studies of OA where comorbidity is common, should be useful in characterizing the global burden of this disease.
IntroductionGender as a predictor of outcomes of rheumatoid arthritis (RA) has evoked considerable interest over the decades. Historically, there is no consensus whether RA is worse in females or males. Recent reports suggest that females are less likely than males to achieve remission. Therefore, we aimed to study possible associations of gender and disease activity, disease characteristics, and treatments of RA in a large multinational cross-sectional cohort of patients with RA called Quantitative Standard Monitoring of Patients with RA (QUEST-RA).MethodsThe cohort includes clinical and questionnaire data from patients who were seen in usual care, including 6,004 patients at 70 sites in 25 countries as of April 2008. Gender differences were analyzed for American College of Rheumatology Core Data Set measures of disease activity, DAS28 (disease activity score using 28 joint counts), fatigue, the presence of rheumatoid factor, nodules and erosions, and the current use of prednisone, methotrexate, and biologic agents.ResultsWomen had poorer scores than men in all Core Data Set measures. The mean values for females and males were swollen joint count-28 (SJC28) of 4.5 versus 3.8, tender joint count-28 of 6.9 versus 5.4, erythrocyte sedimentation rate of 30 versus 26, Health Assessment Questionnaire of 1.1 versus 0.8, visual analog scales for physician global estimate of 3.0 versus 2.5, pain of 4.3 versus 3.6, patient global status of 4.2 versus 3.7, DAS28 of 4.3 versus 3.8, and fatigue of 4.6 versus 3.7 (P < 0.001). However, effect sizes were small-medium and smallest (0.13) for SJC28. Among patients who had no or minimal disease activity (0 to 1) on SJC28, women had statistically significantly higher mean values compared with men in all other disease activity measures (P < 0.001) and met DAS28 remission less often than men. Rheumatoid factor was equally prevalent among genders. Men had nodules more often than women. Women had erosions more often than men, but the statistical significance was marginal. Similar proportions of females and males were taking different therapies.ConclusionsIn this large multinational cohort, RA disease activity measures appear to be worse in women than in men. However, most of the gender differences in RA disease activity may originate from the measures of disease activity rather than from RA disease activity itself.
ObjectiveTo evaluate the safety and efficacy of tocilizumab in clinical practice in patients with rheumatoid arthritis (RA) with inadequate responses (IR) to disease-modifying antirheumatic drugs (DMARDs) or both DMARDs and tumour necrosis factor α inhibitors (TNFis).MethodsPatients—categorised as TNFi-naive, TNFi-previous (washout) or TNFi-recent (no washout) —received open-label tocilizumab (8 mg/kg) every 4 weeks ± DMARDs for 24 weeks. Adverse events (AEs) and treatment discontinuations were monitored. Efficacy end points included American College of Rheumatology (ACR) responses, 28-joint disease activity score (DAS28) and European League Against Rheumatism responses.ResultsOverall, 1681 (976 TNF-naive, 298 TNFi-previous and 407 TNFi-recent) patients were treated; 5.1% discontinued treatment because of AEs. The AE rate was numerically higher in TNFi-recent (652.6/100 patient-years (PY)) and TNFi-previous (653.6/100PY) than in TNFi-naive (551.1/100PY) patients. Serious AE rates were 18.0/100PY, 28.0/100PY and 18.6/100PY; serious infection rates were 6.0/100PY, 6.8/100PY and 4.2/100PY, respectively. At week 4, 36.5% of patients achieved ACR20 response and 14.9% DAS28 remission (<2.6); at week 24, 66.9%, 46.6%, 26.4% and 56.8% achieved ACR20/ACR50/ACR70 responses and DAS28 remission, respectively. Overall, 61.6% (TNFi-naive), 48.5% (TNFi-previous) and 50.4% (TNFi-recent) patients achieved DAS28 remission.ConclusionsIn patients with RA who were DMARD-IR/TNFi-IR, tocilizumab ± DMARDs provided rapid and sustained efficacy without unexpected safety concerns.
The aim of this study is to analyse the psychometric properties of the Italian version of the Chronic Pain Grade (CPG) questionnaire within a population of chronic musculoskeletal pain patients. The CPG questionnaire was adapted following the translation and back-translation methodologies. There were 576 patients with chronic musculoskeletal pain. Internal consistency was checked by the Cronbach's alpha coefficient. Construct validity was analysed by performing principal component factor analysis and by comparing CPG dimensions and subscales with the SF-36 questionnaire. Discriminant validity was assessed by comparing the CPG and SF-36 dimensions in patients with and without other health conditions. Factor analysis yielded two factors which accounted for 76.4% of the variance of the questionnaire. Both subscales of the CPG showed satisfying to good internal consistency. Cronbach's alpha was 0.89 for the first factor 'Disability Score' (58.72% of the explained variance) and 0.81 for the second factor 'Characteristic Pain Intensity' (17.70% of the explained variance). Item-total correlations for the subscales were moderate up to high (from 0.500 to 0.771). In comparison with the SF-36, the expected correlations were found when comparing items measuring similar constructs, supporting the concepts of convergent construct validity. Discriminant validity, assessed by comparing the CPG dimensions in patients with and without other health conditions, showed that the CPG shows moderate association with the presence of co-morbidities. Furthermore, the CPG Disability Score was inversely correlated (p=0.01) to years of formal education. In conclusion, the Italian version of the CPG questionnaire has shown to be valid and reliable for evaluating the severity of chronic musculoskeletal pain, with metric properties in agreement with the original, widely used version.
Osteoporosis and its consequent increase in fracture risk is a major health concern for postmenopausal women and older men and has the potential to reach epidemic proportions. The "gold standard" for osteoporosis diagnosis is bone densitometry. However, economic issues or availability of the technology may prevent the possibility of mass screening. The goal of this study was to develop and validate a clinical scoring index designed as a prescreening tool to help clinicians identify which women are at increased risk of osteoporosis [bone mineral density (BMD) T-score -2.5 or less] and should therefore undergo further testing with bone densitometry. Records were analyzed for 1522 postmenopausal females over 50 years of age who had undergone testing with dual-energy X-ray absorptiometry (DXA). Osteoporosis risk index scores were compared to bone density T-scores. Hologic QDR 4500 technology was used to measure BMD at the femoral neck and lumbar spine (L1-L4). Participants who had a previous diagnosis of osteoporosis or were taking bone-active medication were excluded. Receiver-operating characteristic (ROC) analysis was used to identify the specific cutpoint value that would identify women at increased risk of low BMD. A simple algorithm based on age, weight, history of previous low impact fracture, early menopause, and corticosteroid therapy was developed. Validation of this five-item osteoporosis prescreening risk assessment (OPERA) index showed that the tool, at the recommended threshold (or cutoff value) of two, had a sensitivity that ranged from 88.1 [95% confidence interval (CI) for the mean: 86.2-91.9%] at the femoral neck to 90% (95% CI for the mean: 86.1-93.1%) at the lumbar spine area. Corresponding specificity values were 60.6 (95% CI for the mean: 57.9-63.3%) and 64.2% (95% CI for the mean: 61.4-66.9%), respectively. The positive predictive value (PPV) ranged from 29 at the femoral neck to 39.2% at the lumbar spine, while the corresponding negative predictive values (NPVs) reached 96.5 and 96.2%, respectively. Based on this cutoff value, the area under the ROC curve was 0.866 (95% CI for the mean: 0.847-0.882) for the lumbar spine and 0.814 (95% CI for the mean: 0.793-0.833) for the femoral neck. We conclude that the OPERA is a free and effective method for identifying Italian postmenopausal women at increased risk of osteoporosis. Its use could facilitate the appropriate and more cost-effective use of bone densitometry in developing countries.
Various methods have been used to treat the acute Achilles tendon rupture. Traditional open repair is associated with a higher rate of complications. Percutaneous methods avoid most of the disadvantages of open surgical treatment, but the degree of tendon regeneration cannot be ensured. The authors prospectively followed 40 patients with acute Achilles tendon rupture who underwent percutaneous repair with intraoperative ultrasound assistance an average of 13 months after the injury. No surgery-related complications, such as wounds or deep infections, sural nerve injury, or re-rupture, were detected at follow-up. This technique avoids injury to the sural nerve, minimizes wound complications, and provides a strong repair.
