Insights

Children with nephrotic syndrome, particularly steroid-resistant nephrotic syndrome (SRNS), show reduced protection against diphtheria, tetanus, pertussis, and measles. Booster vaccinations are recommended for these children to ensure adequate immunity.

Area of Science:

  • Pediatric Nephrology
  • Immunology
  • Vaccinology

Background:

  • Nephrotic syndrome can impact immune function and vaccine response.
  • Assessing seroprotective antibody titers is crucial for evaluating vaccine effectiveness in vulnerable pediatric populations.

Purpose of the Study:

  • To evaluate seroprotective antibody titers for diphtheria, pertussis, tetanus, and measles in children with nephrotic syndrome post-immunization.
  • To compare antibody levels between children with steroid-sensitive nephrotic syndrome (SSNS) and steroid-resistant nephrotic syndrome (SRNS).

Main Methods:

  • Antibody titers against diphtheria, pertussis, tetanus, and measles were measured in 76 children (ages 2-18) with nephrotic syndrome in remission.
  • Participants included children with SSNS and SRNS who had completed essential childhood immunizations.

Main Results:

  • Seroprotection rates were 86.8% for diphtheria, 93.4% for tetanus, 31.6% for pertussis, and 77.6% for measles.
  • Children with SRNS exhibited lower seroprotection rates compared to those with SSNS for diphtheria and tetanus.
  • A significant portion of children had elapsed more than 5 years since their last vaccination (68.4%).

Conclusions:

  • Children with nephrotic syndrome, especially SRNS, have diminished seroprotective antibody titers.
  • Booster doses of diphtheria-pertussis-tetanus (DPT) and measles-rubella (MR) vaccines are recommended for children with nephrotic syndrome to maintain adequate immunity.

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 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...

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...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
