Diastolic dysfunction of ventricles in patients with calcium pyrophosphate crystal deposition disease while receiving anti-inflammatory therapy

Abstract

Background. Calcium pyrophosphate crystal deposition disease (CPPD) may be associated with developing of diastolic dysfunction (DD).
 Aim. To determine the variability of echocardiographic parameters in patients with CPPD receiving anti-inflammatory therapy.
 Materials and methods. Twenty six patients with CPPD and osteoarthritis (OA) from 18 to 65 years old were included in the case-control study. All patients underwent echocardiography, laboratory parameters at baseline and after 6 months. Patients with CPPD received methotrexate 15 mg per week or hydroxychloroquine 200 mg once a day, or colchicine 1 mg per day. Diastolic function according to echocardiography was assessed.
 Results. Diastolic dysfunction was detected in 19 patients: in 11 (42%) patients with CPPD and 8 (31%) patients with OA (p=0.39). The baseline serum CRP level was higher in the CPPD group (p=0.03), no differences were found for other indicators. Twenty-two patients with CPPD and 19 patients with OA completed the study. In patients with OA, there were no significant changes in indicators reflecting the diastolic function of ventricles.
 Conclusion. CPPD therapy with colchicine, hydroxychloroquine and methotrexate has a positive effect on indicators of diastolic ventricular function.
