Insights

Long-term corticosteroid use for childhood nephrotic syndrome may stunt adult height. However, cyclophosphamide treatment appears to preserve adult fertility.

Area of Science:

  • Pediatric Nephrology
  • Endocrinology
  • Reproductive Health

Background:

  • Steroid-responsive nephrotic syndrome (SRNS) is a common childhood kidney disease.
  • Long-term management often involves corticosteroids, raising concerns about growth and fertility.
  • The impact of sustained corticosteroid therapy versus intermittent treatment on adult outcomes requires further investigation.

Purpose of the Study:

  • To evaluate the long-term effects of corticosteroid therapy on adult height in patients with childhood SRNS.
  • To assess the fertility outcomes in adult patients previously treated for SRNS.
  • To compare outcomes between patients in sustained remission off corticosteroids and those requiring ongoing steroid therapy.

Main Methods:

  • Retrospective study of 86 adult patients (20-40 years) with childhood-diagnosed SRNS.
  • Analysis of treatment history, including corticosteroid duration and cyclophosphamide use.
  • Assessment of final adult height (standard deviation score) and self-reported fertility (marriage, children).

Main Results:

  • Mean final height was comparable between males and females.
  • Patients requiring continuous corticosteroids for remission had significantly shorter final heights than those in remission off steroids (p < 0.005).
  • Ten cyclophosphamide-treated patients married, and nine had healthy children, suggesting preserved fertility.

Conclusions:

  • Sustained corticosteroid therapy for SRNS in childhood may be associated with reduced adult height.
  • A 12-week course of cyclophosphamide appears to be linked with normal adult fertility.
  • Long-term monitoring of growth and reproductive health is crucial for SRNS survivors.

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2 (COX-2),...

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 fluid...

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 any history...

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...
Cushing Syndrome I: Introduction01:26

Cushing Syndrome I: Introduction

Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
Cushing Syndrome II: Pathophysiology01:19

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
