Background: Systemic lupus erythematosus (SLE) is a life-threatening multisystem inflammatory condition affected any organ system. Considering the role of uric acid as a pro-inflammatory compound in high pulmonary arterial pressure, serum levels of uric acid and its relation to severity and duration of the disease were assessed in SLE patients.
Methods: As a cross-sectional study, 75 patients with SLE were enrolled in Imam Khomeini Hospital and Sahand Clinic. Serum uric acid level was measured by pars azmoon kit. Pearson correlation coefficient and T-test were used for statistical analysis of data.
Results: The mean duration of SLE was 56.44 ± 40.57 months. High serum uric acid was observed in 13.3% of patients with SLE. Moreover, 8% of these patients had high pulmonary arterial pressure. Serum uric acid in patients with high pulmonary artery pressure was significantly higher than patients with normal pulmonary artery pressure (P < 0.01). Furthermore, a significant relation was seen between severity of SLE disease with serum uric acid level and pulmonary artery systolic pressure (P < 0.05). However, there was no significant correlation between serum uric acid level and duration of the disease (p = 0.90, r = 0.016).
Conclusion: According to these results, a significantly increased level of serum uric acid was observed in patients with pulmonary arterial pressure. Hence, serum uric acid level could be a prognostic marker of pulmonary arterial pressure in SLE patients which correlates with disease severity. It also would help to reduce clinical demands for echocardiography in patients with normal uric acid levels.
Key words: Pulmonary arterial hypertension / Serum uric acid / Systemic lupus erythematosus
