Recurrent IgA nephropathy often manifests as persistent microscopic hematuria and urinary protein quantification >0.5g/24h.
Clinically, recurrent IgA nephropathy often manifests as persistent microscopic hematuria and urine protein quantification>0.5g/24h, but usually<3.5g/24h, and less frequently upper respiratory tract infection-associated polyphthalmic hematuria. Pathohistologically, it is mainly a manifestation of mesangial proliferative glomerulonephritis rather than IgA deposition in the mesangial area alone, and sometimes crescentic rapidly progressive renal failure.
Limited to the time point of clinical renal pathology examination, patient compliance, medical conditions and the characteristics of clinical manifestations, the diagnosis of recurrent IgA nephropathy has been reported inconsistently, and there is an obvious gap with the actual clinical data, and the recurrence varies from person to person.
Patients with IgA nephropathy should go to the hospital in time and be treated under the guidance of specialized physicians.
