Intra-articular injection with triamcinolone hexacetonide in patients with rheumatoid arthritis: prospective assessment of goniometry and joint inflammation parameters. 2017
OBJECTIVE To evaluate local joint variables after intra-articular injection with triamcinolone hexacetonide in rheumatoid arthritis patients. METHODS We blindly and prospectively (baseline, 1, 4, 12 and 24 weeks) evaluated metacarpophalangeal, wrist, elbow, shoulder, knee and ankle joints after triamcinolone hexacetonide intra-articular injection by the following outcome measures: visual analogue scale 0-10cm (VAS) for rest pain (VASR); VAS for movement pain (VASM); VAS for joint swelling (VASSw); flexion (FlexG) and extension (ExtG). RESULTS 289 patients (635 joints) were studied. VASSw (p<0.001) and VASR (0.001<p<0.016) improved from T0 to T4, T12 and T24 for all joints. VASM improved from T0 to T4 (p<0.021) for all joints; T0 to T12 (p<0.023) for MCF and knee; T0 to T24 (p<0.019) only for MCF and knee. FlexG improved from T0 to T4 (p<0.001) for all joints; T0 to T12 (p<0.001) and T0 to T24 (p<0.02) only for MCF and knee. ExtG improved from T0 to T4 (p<0.001) for all joints except for elbow; T0 to T12 (p=0.003) for wrist, metacarpophalangeal and knee; and T0 to T24 (p=0.014) for MCF and knee. CONCLUSIONS VASSw responded better at short and medium term after IAI with triamcinolone hexacetonide in our sample of RA patients.
