The goal of this clinical trial is to investigate the effect of the glifozines on albuminuria in chronic kidney disease patients affected by lupus nephritis and ANCA associated renal vasculitis. It will also learn about the safety of glifozines. The main questions it aims to answer are:

• Does glifozines lower the albuminuria of participants with chronic kidney disease secondary to lupus nephritis and ANCA associated renal vasculitis?
• What medical problems do participants have when taking glifozines?

Participants will:

• Take glifozines every day for 6 months.
• Baseline, 1 month and 6-month visits will be scheduled to collect demographic, clinical, biochemical, and urinary data.
• A psychosocial assessment will be performed.

Inclusion Criteria:

• patients aged more than18 years with chronic kidney disease from stage 1 to3, secondary to confirmed LN, without active LN, and AAV

Exclusion Criteria:

• 1) allergy or intolerance to SGLT2i exposure within 1month before screening; 2) recurrent urinary tract infections; 3) hepatic dysfunction (aspartate aminotransferase or alanine aminotransferase levels >2 times the upper normal limits); 4) an eGFR ˂30 ml/min/1.73 m2; 5) DM type I and II.
