What is The renal biopsy of a 6–year–old boy with recurrent gross hematuria shows IgA nephropathy. The urinary protein excretion is 130 mg/day. Which of the following is the most appropriate next step in the management – and explain in detail?
T/T of IgA nephropathy

There is no proven tit for IgA nephropathy.
The primary t/t is proper blood pressure control.

The drugs which have been proved useful are:-
i)  Fish oil (It contains omega - 3 fatty acids).

It is an anti-inflammatory agent and it prevents the rate of renal progression.

ii)   Immunosuppressive therapy -

It is done with corticosteroids with or without cytotoxic therapy.

iii) ACE inhibitors and Angiotensin II receptor antagonists -

Their role in reducing proteinuria and retarding the rate of renal progression is still to be determined.

iv) Prophylactic antibiotics and tonsillectomy -

It may reduce the frequency of gross hematuria but they have no effect on the progression of renal disease.
