[Remission of nephrotic syndrome in patients treated with corticosteroids and other immunosuppressive agents].

INTRODUCTION

Glomerular diseases are hybrid group, mostly immunologically related kidney diseases where pathologic changes start in glomerules, but afterwards within their further process they grasp the other kidney structures. The most common clinical manifestation of the primary glomerulonephritis in the adults is nephrotic syndrome. Therefore, this elaboration aims are to estimate the therapy effect onto the different pathohistologic forms of the primary nephrotic syndrome.

MATERIAL AND METHODS

Study has been conducted on 41 patients having the primary nephrotic syndrome, prior having normal kidney function. Different pathohistological forms of NS were verified by percutaneous kidney biopsy. Depending on the pathohistological finding the different therapeutic protocoles were applied. Each of the monitored patients were treated by giving steroids at least six weeks dosing them 2 mg/kg/bw/48 h, but not higher then 130 mg/48 h. In the cases of the patients having the given therapy, it did not lead them to the nephrotic syndrome remission, cyclophosphamid was induced in the dosage of 1.5-2.0 mg/kg/bw/48 h. According to the therapy reaction the patients were divided in three groups: the patients with the complete remission, with partial remission and the patients resistant to the treatment.

THE RESULTS

41 patients have been observed, 28 male and 13 female, aged between 16-69, average 32.3 years old. All patients had normal kidney function, and diseases duration from the moment of the pathohistomorphologic diagnosis had been lasting 0-2 years, from average 6.4 months. According to pathohistological diagnosis the patients were divided into four groups: a) "minimal changes" MCNS (n -11), b) focal--segmental glomerulosclerosis FSGS (n - 10) c) membraneous glomerulonephritis MGN (n-9) d) membranoproliferative MPGN (n-10). The best therapy effect had been resulted within the group with MCNS having 82% cases with the complete remission, while the group with MCNS had reacted the most adversely, 45% were resistant onto the therapy. 18 patients of the total 41 had the complete remission, 14 partial remission, and 9 of them were without remission.

CONCLUSION

The patient having the minimal changes had the best response onto the steroids therapy, while the patients having the expressive proliferative changes did not respond with the complete remission.
