Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Urinary T lymphocytes may be predictive for clinical outcome in patients with ANCA associated glomerulonephritis (ANCA GN). The investigators hypothesize that the amount of CD4+ effector/memory T cells in urine at time of diagnosis predicts the outcome of patients with active ANCA GN after 6 months of therapy. In a prospective, six-months follow-up study patients' urine will be analysed by flow cytometry every 60 days (+/- 10d). Treatment will be performed to the discretion of the treating clinician. After 6 months of treatment response will be determined as either complete response or partial response.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active ANCA glomerulonephritis

Patients with ANCA related disease (Microscopic Polyangiitis, Granulomatosis with Polyangiitis or Churg-Strauss Syndrome) and active renal involvement

Flow cytometry analysis of urine samples

Intervention Type DIAGNOSTIC_TEST

Urine samples will be conserved and frozen upon arrival. All samples will be stained according to T cell and TEC (tubular epithelial cells) panel with fluorochromes.

T cell panel: CD3, CD4, CD8, CCR7, CD45RO, CD28, CD279; TEC panel: vimentin, cytokeratine, CD10, CD13, CD227, CD326

Control

Patients with ANCA related disease (MPA, GPA, CSS) without renal involvement or complete remission

Flow cytometry analysis of urine samples

Intervention Type DIAGNOSTIC_TEST

Urine samples will be conserved and frozen upon arrival. All samples will be stained according to T cell and TEC (tubular epithelial cells) panel with fluorochromes.

T cell panel: CD3, CD4, CD8, CCR7, CD45RO, CD28, CD279; TEC panel: vimentin, cytokeratine, CD10, CD13, CD227, CD326
