Abstract:
Objective To analyze the clinical typing, pathological classisfication, and prognosis of primary IgA nephropathy (IgAN).Methods Clinical typing, pathological classisfication and relationship between clinical manifestations and pathological features of 220 cases with IgAN were analyzed in 10 years.Results IgA nephropathy occupied 42.9％ (220/512) of all the patients received renal biopsy at the corresponding time.Asymptomatic abnormal urinalysis was the most common clinical manifestation(39.0％ (86/ 220)), followed by hypertension (17.7％ (39/220)) and recurrent macroscopic hematuria (15.4％ (34/220)).Grade Ⅲ pathological change(29.5％ (65/220)) was the most co mmon,followed by grade Ⅱ (27.3％ (60/ 220)) and grade Ⅳ (18.2％), Grade Ⅰ/Ⅴ were relatively less ((11.4％ (25/220), 13.6％ (30/220)).No correlation could be found between types of deposited immune complex and pathological lesion extent(x2=4.87, P＞0.05).The clinical manifestations were significantly correlated with the severity of glomerular lesions (x2 =13.14,P＜0.05).During the follow-up for 106 patients (mean duration of 23 months), 90 patients(84.9％) had normal renal function and 75 patients(70.8％) had decreased excretion of protein in urine (＜1 g/24 h).Conclusion The clinical typing of primary IgA is correlated with pathological changes.The prognosis of IgA is markedly correlation with the pathological lesion degree.Renal functions will be improved if the different treatments were given according to the different renal pathological features.
