Abstract

Insights

Mycophenolate mofetil (MMF) offers long-term steroid-sparing benefits for pediatric nephrotic syndrome (NS) patients. Over 50% of severe steroid-dependent NS cases avoided further immunosuppression with MMF therapy.

Area of Science:

  • Pediatric Nephrology
  • Immunosuppressive Therapy

Background:

  • Mycophenolate mofetil (MMF) is utilized as a steroid-sparing agent in pediatric nephrotic syndrome (NS).
  • Limited data exists on the long-term efficacy and safety of MMF in this population.

Purpose of the Study:

  • To evaluate the long-term outcomes of Mycophenolate mofetil (MMF) therapy in pediatric patients with steroid-dependent nephrotic syndrome (SDNS).

Main Methods:

  • A cohort of 46 pediatric NS patients, steroid-dependent despite prior levamisole and cyclophosphamide treatment, received MMF.
  • Long-term outcomes, including steroid requirements, relapse rates, and adverse events, were assessed.

Main Results:

  • Within one year, 70% of patients showed reduced steroid needs, with 20 achieving complete steroid cessation.
  • At a mean follow-up of 3.56 years, 54% of children no longer required alternative immunosuppression (IS), experiencing infrequent relapses.
  • One patient experienced a psoriasis flare; no other permanent drug withdrawals due to side effects were noted.

Conclusions:

  • Long-term Mycophenolate mofetil (MMF) therapy is safe for pediatric nephrotic syndrome (NS) patients.
  • MMF enables over 50% of severe steroid-dependent NS patients to avoid additional toxic immunosuppressive (IS) agents.

Nephrotic Syndrome III : Nursing Management

Nursing management for nephrotic syndrome adapts as the disease progresses, with strategies evolving to address advancing symptoms and complications.Early-Stage Management In the early stages, nursing interventions for nephrotic syndrome resemble those used in managing acute glomerulonephritis, focusing on symptom monitoring, fluid balance, and managing mild to moderate edema.Vital Signs: Regularly monitor blood pressure, pulse, respiratory rate, and temperature to promptly identify...

Nephrotic Syndrome II : Assessment and Medical Management

IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Frequency-dependent Selection01:21

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.
