Clinical Trial: Analysis of T- and B-Cell Subpopulations in Membranous Nephropathy

Study Type: OBSERVATIONAL



Official Title: Analysis of T- and B-Cell Subpopulations in Patients With Primary Membranous Nephropathy

Brief Summary:

The aim of this observational study is to provide analysis of T and B lymphocyte subgroups in peripheral blood samples of patients with primary membranous nephropathy (MN).
A search for disease-related circulating antibodies [anti-phospholipase A2 receptor antibody (anti-PLA2R) and anti-thrombospondin type 1 domain-containing 7A antibody (anti-THSD7A)] in patients' sera is also planned.

The main questions to answer are:

  1. What is the relationship of these cell populations and their distribution during follow-up with treatment, treatment responses, and relapses?
  2. What is the relationship of the cell populations with anti-PLA2R (or anti-THSD7A) antibody levels?

Participants will provide peripheral venous blood samples at pre-designated regular intervals.

The research team will compare results of the primary MN group with two control groups (IgA nephropathy and healthy volunteer groups) to see if the findings are specific for primary MN.
