The objective was to investigate the predictive factors for avascular necrosis (AVN) of bone in patients with systemic lupus erythematosus (SLE). The records of 868 patients with SLE from four centers were reviewed retrospectively. Forty-nine patients with AVN were identified. A total of 154 patients with SLE who did not have clinically apparent AVN during the follow-up were evaluated as a control group. The demographic, clinical, laboratory and management characteristics of these two groups of patients were recorded according to predefined protocol and compared. The prevalence of AVN was detected 6% in our SLE population. The highest dose corticosteroid administered within 4 months and total cumulative prednisolone dose were significantly higher in the SLE patients with AVN. The use of cytotoxic agent significantly higher proportion of patients with AVN. AVN tends to develop more frequently in male gender and younger patients. Oral ulcer, pleuritis, Raynaud's phenomenon, cutaneous vasculitis, lymphadenopathy, autoimmune thyroiditis, peripheral neuropathy and Sjögren's syndrome were higher incidence in SLE patients with AVN. The bilateral femoral heads were the commonest site of involvement of AVN in our patients with SLE.
The aim of this study was to compare and evaluate the Health Assessment Questionnaire (HAQ) and Arthritis Impact Measurement Scale (AIMS) in our patient population with rheumatoid arthritis (RA) and also to find some associations with clinical assessment of disability. One hundred and twenty-three consecutive adult patients with RA were included in the study. Pain, and global assessments by patients and physicians were recorded using a 10 cm visual analogue scale. Each patient completed the HAQ and AIMS questionnaires. Correlations among tender and swollen joint counts, erythrocyte sedimentation rate, pain, and AIMS anxiety and depression scores were all investigated. Pearson correlation was used to assess the possible correlations between each questionnaire and clinical variables. Pain and the AIMS subscales of mobility, dexterity, social activity and activities of daily living correlated with global assessments by patients and physicians, and tender joint counts. Depression correlated with pain and disability (HAQ). It was also of note that we observed high intercorrelation between the global assessments of physicians and patients. It was concluded that a measure of functional status, patient global assessment and pain score should be considered as important in the evaluation of RA patients. Measuring psychological well-being also provides further information. The HAQ, with the addition of the anxiety and depression sections of AIMS (CLINHAQ), provides the advantage of a global evaluation of these chronically ill patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
