A case of emphysematous pyelonephritis in a patient with rheumatoid arthritis taking corticosteroid and low-dose methotrexate.

Rheumatoid arthritis (RA) is a systemic autoimmune disease that is characterized by chronic synovial inflammation. Patients with RA have increased risk of infection; this is related to RA itself or the adverse effects of medication. In this report, we describe a case of emphysematous pyelonephritis in a patient with RA associated with AA amyloidosis and steroid-induced diabetes mellitus who was taking corticosteroid and low-dose methotrexate.

Thrombin-cleaved osteopontin is increased in urine of patients with rheumatoid arthritis.

Objective: To measure concentrations of the thrombin-cleaved isoform of osteopontin (OPN) in urine and plasma of patients with rheumatoid arthritis (RA), and to assess whether levels of thrombin-cleaved OPN are associated with measures of RA.

Methods: Subjects comprised 70 patients with RA, 20 patients with osteoarthritis (OA), and 46 healthy controls. RA disease activity was evaluated by tender joint count, swollen joint count, patient's global assessment of disease activity, erythrocyte sedimentation rate (ESR), and levels of C-reactive protein (CRP), matrix metalloproteinase-3 (MMP-3), and rheumatoid factor (RF), as well as 28-joint count Disease Activity Score (DAS28).

Doppler sonographic analysis of synovial vascularization in a patient with rheumatoid arthritis treated with leukocytapheresis.

Synovial vascularization in metacarpophalangeal joints of a patient with rheumatoid arthritis treated with leukocytapheresis (LCAP) was evaluated by Doppler sonography. After the treatment with LCAP, evaluation with American College of Rheumatology core set showed improvement, and the levels of C-reactive protein and serum amyloid A protein decreased. Power Doppler sonography demonstrated a reduction of color flow signals of the joints, and spectral Doppler sonography demonstrated an increase in vascular resistant, indicating a reduction of vessel's permeability.
