ABSTRACT

Objective To study the relationships between pathological grade of Henoch-Schonlein purpura nephritis (HSPN) and levels of serum transforming growth factor-beta 1 (TGF-β1),monocyte chemoattractant protein 1 (MCP-1),interleukin (IL)-17 and prognosis in adults.Methods 98 HSPN patients treated in our hospital from June 2015 to December 2017 were selected as the study group,65 IgA nephritis patients were selected as the IgA nephritis group,and 60 healthy people who came to our hospital for physical examination during the same period were selected as the control group.The levels of TGF-β1,MCP-1 and IL-17 in serum of the three groups were detected,and the Cox regression analysis was used to analyze the risk factors affecting the patient's condition.Results The levels of serum TGF-β1,MCP-1 and IL-17 in the study group were significantly higher than those in IgA nephritis group and control group (P ＜ 0.05).The levels of serum TGF-β1,MCP-1 and IL-17 in IgA nephritis group were significantly higher than those in control group (P ＜ 0.05).There was no significant difference in age,sex,hemoglobin,albumin,urinary protein and renal phenotype among groups (P ＜ 0.05).Platelets of type Ⅲ were significantly lower than those of type Ⅱ (P ＜0.05);C-reactive protein (CRP) level of type Ⅳ,Ⅴ and Ⅵ was significantly higher than that of type Ⅱ (P ＜ 0.05).The degree of glomerulosclerosis in patients with type Ⅲ,Ⅳ,Ⅴ and Ⅵ was significantly higher than that in patients with type Ⅱ,and the degree of glomerulosclerosis in patients with type Ⅴ and Ⅵ was also significantly higher than that in patients with type Ⅲ (P ＜ 0.05).The formation of crescents in patients with type Ⅲ,Ⅳ,Ⅴ and Ⅵ was significantly higher than that in patients with type Ⅱ,and the formation of crescents in patients with type Ⅳ,Ⅴ and Ⅵ was also significantly higher than that in patients with type Ⅲ (P ＜ 0.05).The levels of serum TGF-β1,MCP-1 and IL-17 were the lowest in type Ⅱ patients and the highest in type Ⅴ and Ⅵ patients.The levels of TGF-β1,MCP-1 and IL-17 in type Ⅲ,Ⅳ,Ⅴ and Ⅵ were significantly higher than those in type Ⅱ (P ＜0.05),and the level of TGF-β1 in type Ⅳ,Ⅴ and Ⅵ was significantly higher than that in type Ⅲ (P ＜ 0.05);Serum IL-17 level of type Ⅴ and Ⅵ was significantly higher than that of type Ⅲ (P ＜ 0.05).Cox regression analysis showed that TGF-β1 and IL-17 were risk factors for pathological grading.Conclusions The higher the pathological grade of Henoch-Schonlein purpura nephritis in adults,the higher the levels of serum TGF-β1 and IL-17.TGF-β1 and IL-17 are the risk factors affecting the pathological grade of Henoch-Schonlein purpura nephritis.
