Corticosteroids are the main therapy of nephrotic syndrome and goal of corticosteroid therapy is to obtain maximum clinical benefit with minimum adverse effects. Children are more vulnerable to side effects of corticosteroids related to growth and adrenal suppression, so a search for an alternative steroid with fewer side-effects is underway. Deflazacort is an oxazoline derivative and preliminary data suggest reduced osteoporosis, lesser growth retardation and weight gain with deflazacort.
This study was done to compare the effectiveness and safety of deflazacort in idiopathic nephrotic syndrome.
Twenty five children with age between 2 to 12 years, with idiopathic nephrotic syndrome were enrolled. They were randomly assigned to receive deflazacort (Group A, n = 12) or prednisolone (Group B, n = 13) and were followed up for six months.
All children of group A and 11 of group B had remission. Two children from group B were steroid resistant. Mean time taken to induce remission was significantly (P = 0.012) less in group A (10.25 ± 2.41 days) than group B (12.55 ± 1.44 days). One patient in group A had relapse on follow up as compared to 3 in group B (P = 0.58). Statistically significant difference (P = 0.03) in change in mean height was found between group A (2.13 ± 0.50cm) and B (1.44 ± 0.45 cm), with group B gaining less height.
Remission rate in both groups was comparable although time taken to induce remission was shorter in deflazacort group and there was a significant difference in change of mean height on follow up with prednisolone group gaining lesser height.
皮质类固醇是肾病综合征的主要治疗方法,皮质类固醇治疗的目标是以最小的不良反应获得最大的临床益处。儿童更容易受到与生长和肾上腺抑制相关的皮质类固醇副作用的影响,因此正在寻找一种副作用较少的替代类固醇。地夫可特是一种恶唑啉衍生物,初步数据表明地夫可特可减少骨质疏松症、减轻生长迟缓并减少体重增加。
本研究旨在比较地夫可特治疗特发性肾病综合征的有效性和安全性。
纳入25例年龄在2至12岁之间的特发性肾病综合征患儿。他们被随机分配接受地夫可特(A组,n = 12)或泼尼松龙(B组,n = 13),并随访6个月。
A组所有患儿和B组11例患儿病情缓解。B组有2例患儿对类固醇耐药。A组诱导缓解的平均时间(10.25 ± 2.41天)明显(P = 0.012)短于B组(12.55 ± 1.44天)。随访期间,A组有1例患者复发,而B组有3例(P = 0.58)。A组(2.13 ± 0.50cm)和B组(1.44 ± 0.45 cm)之间平均身高变化存在统计学显著差异(P = 0.03),B组身高增长较少。
两组的缓解率相当,尽管地夫可特组诱导缓解的时间较短,且随访时平均身高变化存在显著差异,泼尼松龙组身高增长较少。
