Brief Summary

Influence factors and preliminary mechanism of high incidence of thrombotic events in patients with idiopathic membranous nephropathy and diabetes kidney disease

Detailed Description

According to the results of renal biopsy, the patients were divided into three groups: membranous nephropathy group (MN), non-membranous nephropathy group (non-MN) and diabetes kidney disease group (DKD). Collect the basic data and TEG test results of the enrolled patients. (1) ① According to TEG results, the enrolled patients were divided into two groups: hypercoagulable group (CI \> 3) and non-hypercoagulable group (CI ≤ 3). The basic data and related laboratory indicators of the two groups were compared - to explore the influencing factors of hypercoagulable (objective X); ② Compare the parameters related to TEG and coagulation routine between MN group and non-MN group, DKD group and non-MN group respectively - find out the coagulation index (target Y) of the difference between groups; ③ Build regression models for different target Y - explore the influencing factors of grouping variables (MN vs non MN or DKD vs non MN) on Y after adjusting other covariates; (2) ① According to whether the patients in the group had thrombotic events or not, all the patients in the group with thrombotic events were divided into MN thrombotic events group and non-MN thrombotic events group according to pathological diagnosis, and the TEG, coagulation and other related laboratory results and basic data between the two groups were compared (explore the unique factors and processes that affect the occurrence of thrombotic events in MN group compared with non-MN group); ② According to whether the patients in the MN group who were hospitalized for many times had thrombotic events, the patients were divided into the MN group with thrombotic events and the MN group without thrombotic events. The TEG, coagulation and other related laboratory results and basic data between the two groups were compared (to explore the factors and processes that affect the occurrence of thrombotic events in the MN group).

Primary Outcome Measures

Name	Time	Method
Specific link between high incidence of thrombotic events in patients with membranous nephropathy and diabetic nephropathy	2021-2024	① Based on collecting whether all the patients enrolled in multiple hospitalizations had thrombotic events, all the patients enrolled with thrombotic events were divided into MN with thrombotic events group and non MN with thrombotic events group according to the pathological diagnosis, and relevant assay results such as TEG, coagulation and basic data were compared between the two groups (to explore the specific factors and processes influencing the occurrence of thrombotic events specifically in the MN group compared to the non MN group); ② Based on whether thrombotic events occurred in patients within the Mn group enrolled in multiple hospitalizations, patients were divided into Mn with thrombotic events and Mn without thrombotic events groups, and relevant laboratory results and basic data such as TEG and coagulation were compared between the two groups (to explore factors and processes influencing the occurrence of thrombotic events in patients within the MN group).
Factors influencing the high incidence of thrombotic events in patients with membranous nephropathy and diabetic nephropathy	2021-2024	Collect the basic data of the enrolled patients, including admission blood pressure, smoking, drinking history, the use of statins, anticoagulants and antiplatelet drugs, and blood test indicator. All indicators for inclusion in the analysis are presented in full by subgroup. ① the enrolled patients were divided into two groups according to TEG results: hypercoagulable group (CI \> 3) vs non hypercoagulable group (CI ≤ 3). The basic data and related laboratory parameters of the two groups were compared to explore the influence of hypercoagulability factors (AIM X); ② Comparison of TEG and coagulation routine related parameters between MN and non MN group, DKD and non MN group - to find the coagulation indexes (target Y) that differ in TEG and coagulation routine between groups; ③ Regression models were constructed separately for different targets Y - to explore the influence of grouping variables (MN vs non MN or DKD vs non MN) on y after adjusting for other covariates;
