This study focuses on children with steroid-sensitive idiopathic nephrotic syndrome, a kidney condition that causes protein to leak into urine. The research examines whether adding levamisole to standard treatment can prevent the disease from coming back. The medication being tested is called Elmisol, which comes in different strength tablets (5 mg, 10 mg, 25 mg, and 50 mg).
The purpose of this research is to determine if using levamisole together with corticosteroids (standard treatment) for 6 months can reduce the chances of the disease returning within 12 months. Some patients will receive levamisole tablets while others will receive placebo tablets. The treatment period lasts for 24 months, during which doctors will monitor how often the disease returns and check for any side effects.
During the study, doctors will track how quickly and how often the disease returns, measure the total amount of medications needed, and monitor various health indicators. They will also keep records of any missed school days and hospital visits. The medication is taken by mouth, and the dose is calculated based on the patient’s weight.
