Rheumatology International, 10/26/09
Martinez-Valle F et al. – The objective of the study is to determine whether the activity of DNase1 is associated to the presence of nephropathy in patients with SLE. We conclude that low DNase1 activity is associated to the active phase of type III or IV nephropathy. Therefore, it is possible that this enzyme plays an important role in the development of SLE nephropathy.
Methods- 45 rty-five patients affected with SLE and renal involvement analyzed
- Type of renal involvement was type III or IV glomerulonephritis
- At least 2 serum samples withdrawn from each patient, 1 obtained in renal flare and other obtained in period of clinical stability
- C3 and C4 complement levels and anti-DNA antibodies determined
- DNase1 activity measured using a radial enzyme-diffusion method
- Results suggest that when comparison of DNase1 activity was established between samples obtained during a phase of active renal involvement and those obtained in the clinically stable phase, no statistically significant differences found
- When comparison was performed with matched samples of same patient, DNase1 activity lower when patients had active renal involvement than when samples taken in clinically stable phase
- No difference in DNase1 activity observed between samples positive or negative for anti-DNA antibodies
- No difference in DNase1 activity found in patients with normal or decreased levels of C3 or C4
