Managing Frequently Relapsing Childhood Nephrotic Syndrome: A Novel Combination of Synacthen and Mycophenolate Mofetil

Childhood nephrotic syndrome is a prevalent renal disorder characterized by generalized edema due to hypoalbuminemia from heavy proteinuria. This syndrome can be classified as primary or secondary, with the majority of cases being primary. Historical perspectives on nephrotic syndrome illustrate significant advancements in understanding its pathology and treatment, beginning with early descriptions in the 15th century and evolving through the introduction of terms like "nephrosis." Current management primarily relies on corticosteroids, but issues such as frequent relapses and steroid dependency necessitate alternative therapies. Recent approaches include the use of levamisole and mycophenolate mofetil, alongside the resurgence of intramuscular ACTH (synacthen) as a treatment option. This article presents a case study of a boy with frequently relapsing steroid-dependent nephrotic syndrome, successfully treated with a novel combination of intramuscular synacthen and mycophenolate mofetil. This regimen effectively reduced the required dosage of steroids while minimizing associated adverse effects, particularly psychiatric symptoms. The findings underscore the potential for innovative therapeutic strategies in managing challenging cases of childhood nephrotic syndrome.
