Abstract:Objective To explore the changes of serum pentamerin-3 (PTX3) and IgA/C3 levels in patients with purpuric nephritis and their correlations with renal damage. Methods The 96 patients with purpuric nephritis treated with mycophenolate mofetil combined with prednisone treated in our hospital between May 2014 and June 2019 were selected as the treatment group while another 80 healthy physical examinees in the same period were selected as the control group. The changes of serum levels of immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M (IgM), complement C3 (C3) and PTX3 in the two groups were observed. The IgA/C3 value was calculated, while the difference in serum IgA/C3 levels and renal function indexes was compared between the two groups. The Pearson method was used to analyze the correlations between serum PTX3, IgA/C3 levels and renal impairment in patients with purpuric nephritis treated with mycophenolate mofetil combined with prednisone. Results Serum levels of IgA, PTX3, IgA/C3, and SCr in the treatment group were significantly higher than those of the control group, but serum IgG, IgM, eGFR, and α-MG levels were significantly lower (P<0.05). Pearson correlation analysis showed that serum IgA/C3 and PTX3 levels were positively correlated with serum SCr levels, but negatively with serum eGFR and α-MG levels (P<0.05). Conclusions After combined treatment with mycophenolate mofetil and prednisone, the serum PTX3 and IgA/C3 levels of patients with purpuric nephritis have been improved to some extent, and they are positively correlated with renal function damage.
