The relation between joint erosion and generalized osteoporosis and disease activity in patients with rheumatoid arthritis.
The aim of this study is to investigate the correlation between joint erosion and osteoporosis in patients with rheumatoid arthritis (RA). Fifty-one patients with RA were included for the study. Hand radiograms of all patients were evaluated by the Larsen modified Sharp and carpometacarpal ratio methods. Bone mineral density (BMD) measurements were performed at the femur, lumbar, and forearm regions. Disease activity was assessed clinically by the health assessment questionnaire (HAQ), visual analog scale, erythrocyte sedimentation rate, C-reactive protein (CRP), and the rheumatoid factor (RF). There was no statistically significant difference in terms of the BMD values at L1-4 between the patients with RA and the control group. The BMD measurements at the right forearm and the right hip were statistically significantly lower in the patient group. For radiological scoring, hand radiograms were evaluated by three different methods. There was a significant correlation between the duration of disease and the radiological evaluation methods. HAQ scores, Larsen and Sharp methods 1/3 distal and mid-distal (MID), and BMD measurements of the forearm were correlated. Moreover, 1/3 distal, MID, and ultra-distal BMD showed significant correlations with CRP levels. Radiogram continues to have an important role in determining and following-up the joint erosion seen in patients with RA. However, we believe that as establishing periarticular osteoporosis in the early term by performing BMD measurements on the forearm is correlated with disease activity, it may be useful in the early diagnosis of RA and its objective results will be efficient in predicting the progression of disease.
