Effect of long-term low dose prednisolone administration on bone mineral density: Relating to non-compliant women with rheumatoid arthritis

Background: Long-term treatment of rheumatoid arthritis (RA) with prednisolone (PRED) is associated with bone mineral density (BMD) loss. This study aimed to determine the status of BMD in non-compliant women who used PRED alone for RA. Methods: Non-adherent RA taking < 7.5 mg daily PRED without...

Description
Summary:Background: Long-term treatment of rheumatoid arthritis (RA) with prednisolone (PRED) is associated with bone mineral density (BMD) loss. This study aimed to determine the status of BMD in non-compliant women who used PRED alone for RA. Methods: Non-adherent RA taking < 7.5 mg daily PRED without DMARDs for > 6 months, and RA patients taking methotrexate +PRED (RA control) were compared with age-matched non-RA controls. BMD was measured by dual energy x-ray absorptiometry (DXA) method and osteoporosis (OP) was diagnosed by WHO criteria. Influence of PRED on RA bone mass, and the risk of OP in RA &nbsp;was assessed by comparing PRED users RA and RA control,versus non-RA controls. Results: Sixty-four PRED user RA, 39 RA controls and 111 non RA-controls, with respective mean (&plusmn;SD) age of 52&plusmn;11; 8, 51&plusmn;11; and 52&plusmn;7.5 years (p=0.91) were studied. Median duration of treatment in PRED users and RA control was 2.5 and 4 years, respectively. BMD g/cm2 at the femoral neck (FN-BMD) and lumber spine (LS-BMD) in PRED users and RA control was significantly lower than non-RA control (P=0.001). The prevalence of OP at either FN or LS in both RA groups was significantly higher than controls (P=0.001). In PRED users, the risk of OP increased by OR=4.9, P=0.001) and in RA controls by OR=1.7 (P=0.20). The risk of OP in PRED user RA was 2.89 times (P=0.014) greater than RA controls. Conclusions: These findings indicate significantly lower BMD, and higher prevalence of osteoporosis in non-compliant women with RA taking low-dose PRED alone for a median period of 2.5 years, as compared with patients taking standard treatment comprising methotrexate +PRED. &nbsp;
