Supportive treatment, including administering angiotensin-receptor blockers (ARBs) and salt restriction, should be administered to all IgAN patients (1)

A low protein diet is also advisable in nephrotic IgA nephropathy patients (1)

If recurrent chronic tonsillar infections then tonsillectomy is indicated

Use of immune-suppressive agents depends mainly upon the progression rate, comorbidities, and histopathological changes of the kidney biopsy (1):

  • corticosteroids are currently the cornerstone of IgA nephropathy
    • NICE have stated that
      • Targeted-release budesonide is recommended as an option for treating primary immunoglobulin A nephropathy (IgAN) when there is a risk of rapid disease progression in adults with a urine protein-to-creatinine ratio of 1.5 g/g or more (3)

it is an add-on to optimised standard care including the highest tolerated licensed dose of angiotensin-converting enzyme (ACE) inhibitors or angiotensin-receptor blockers (ARBs), unless these are contraindicated

  • different therapeutic agents such as calcineurin inhibitors (CNIs), cyclophosphamide, mycophenolate mofetil, rituximab, and leflunomide (LEF) are used, but none is approved as a single or combined effective therapy for IgA nephropathy
