Nephrotic syndrome: from toddlers to twenties

63 patients with steroid-sensitive, biopsy-proven minimal-change nephrotic syndrome were followed for between 10 and 21 years. 2 died. All the survivors had normal renal function and blood pressure, and only 2 had a single attack. Frequent relapse was more common with young age of onset and in boys. The frequency of relapse fell rapidly over the first 4 years after diagnosis and then plateaued. Relapses continued into adult life. No definite endpoint to the disease could be defined although there was a linear relation between length of remission and risk of subsequent relapse.
