[Influential factors for theraputic effect of steroid on adult primary nephrotic syndrome].

OBJECTIVE: To determine the factors associated with the eff ect of steroid on adult primary nephrotic syndrome. METHODS: The general information, laboratory examination and renal pathological type of 425 patients with primary nephrotic syndrome were retrospectively analyzed. RESULTS: Th ere were significant differences in the response to steroid among the pathological types of minimal change disease, focal segmental glomerulosclerosis and IgA nephropathy. Th e patients in the age of 14-24 years old showed the strongest response to steroid (P<0.05). Th e IgA level in the steroid resistance group was lower than that in the non-steroid resistance group (P<0.05). There was no significant difference in urine protein in 24 hour quantitation in the steroid resistance group between pre- and post-treatment (P>0.05), while there was significant difference in urine protein in 24 hour quantitation in the non-steroid resistance group between pre- and post-treatment (P<0.05). CONCLUSION: Pathological types and ages of the patients are related to the steroid curative effect. The decrease in IgA probably affects the effect of steroid on primary nephrotic syndrome.
