NCT06245707

Brief Summary

This study intends to apply prospective, open, single-center, randomized controlled study to evaluate the cognitive status of patients with Idiopathic membranous nephropathy and the influence of different treatment schemes on the cognitive status of patients with Idiopathic membranous nephropathy, and explore the possible pathophysiological mechanism by using brain magnetic resonance imaging technology.

Outcome Measures

Primary Outcomes (1)

  • The cognitive function of the two groups was evaluated and analyzed by the Chinese version of Montreal Cognitive Assessment Scale (MoCA)

    The two groups of patients were given a quiet environment and completed the test within 10 minutes. The cognitive function of the two groups was evaluated and analyzed by the Chinese version of Montreal Cognitive Assessment Scale (MoCA). The possible score was between 0 and 30. The higher the score, the better the cognitive state. We defined cognitive impairment as a total score of less than 26 for participants with high school education or below and less than 27 for participants with high school education or above, because the average score of MOCA varies according to the level of education

    enrollment, half a year after treatment and one year after treatment.

Secondary Outcomes (1)

  • Brain magnetic resonance high-resolution structural imaging was performed to observe the changes of brain structure

    enrollment, half a year after treatment and one year after treatment.

Study Arms (2)

Ponticelli group

EXPERIMENTAL

Patients with idiopathic membranous nephropathy were treated with Ponticelli protocol,that is alternating prednisone or methylprednisone -cyclophosphamide every other month

Drug: prednisone,methylprednisone and cyclophosphamide

Rituximab group

EXPERIMENTAL

Patients with idiopathic membranous nephropathy were treated with Rituximab.The specific dosage of rituximab depends on the guidance of peripheral blood B cells.

Drug: Rituximab

Interventions

In the first month, methylprednisolone 500mg/d was given intravenously for 3 days, and then prednisone 0.5 mg/(kg d) \* for 27 days. Oral cyclophosphamide 2.0 mg/(kg d) \* 30 days in the second month. After that, the first month and the second month plan were repeated twice.

Ponticelli group

The dosage of rituximab depends on peripheral blood B cells. After the treatment of rituximab, the peripheral blood B cells were in a clear state and then stopped. After monitoring the recovery of B cells, additional doses were given.

Rituximab group
