Analysis of the clinical characteristics and the Oxford classification of 192 cases of IgA nephropathy / 中国医师杂志

ABSTRACT

Objective To investigate the relationship of the clinical characteristics and the Oxford classification of IgA nephropathy.Methods Clinical presentation (age,gender,course of disease,blood pressure,hematuria,24-hour proteinuria,serum creatinine,serum albumin,triglyceride,cholesterol,and estimated glomerular filtration rate (eGFR)),pathological data (mesangial hypercellularity,endocapillary hypercellularity,segmental sclerosis or adhesions,tubular atrophy or interstitial fibrosis,artery score,and cellular + fiberocellular crescents) and their correlation of 192 patients with IgA nephropathy patients were analyzed.Results (1)Clinically,hematuria + albuminuria type was the most common among 192 the patients with IgA nephropathy (72 cases,37.5％) followed by nephrotic syndrome (42 cases,21.9％),renal insufficiency (29 cases,15.1％),hypertension (72 cases,37.5％).(2)M1 was 60.0％,E1 was 55.2％,S1 was 46.9％,T0,T1,T2 were 59.9％,22.9％,and 17.2％,respectively,small artery thickening was 46.9％,patients with cellular + fiberocellular crescents wais 48.5％.Some pathology features were related to age.(3)Proteinuria was associated with the mesangial hypercellularity score,endocapillary hypercellularity,segmental sclerosis or adhesions,and tubular atrophy or interstitial fibrosis and cellular + fiberocellular crescents.Blood pressure and renal function were associated with segmental sclerosis or adhesions,tubular atrophy or interstitial fibrosis,small artery thickening and cellular + fiberocellular crescents.Conclusions The Oxford classification has a good clinical guide of treatment and prognosis of IgA nephropathy.
