Insights

Steroid therapy for nephrotic syndrome can cause posterior subcapsular cataract (PSCC) and raised intraocular pressure (IOP) in children. Regular eye exams are crucial, as cumulative steroid dose and duration did not correlate with these ocular complications.

Area of Science:

  • Pediatric Nephrology
  • Ophthalmology
  • Pharmacology

Background:

  • Long-term steroid therapy is common for childhood nephrotic syndrome.
  • Steroids can lead to ocular complications like posterior subcapsular cataract (PSCC) and raised intraocular pressure (IOP).
  • The relationship between steroid dosage/duration and these complications in children requires further investigation.

Purpose of the Study:

  • To determine the prevalence of PSCC and raised IOP in children with nephrotic syndrome on long-term steroid treatment.
  • To assess the correlation between cumulative steroid dosage and duration of therapy with the development of PSCC and raised IOP.

Main Methods:

  • Cross-sectional study including children aged 4-18 years with nephrotic syndrome on steroids for at least six months.
  • Data collected from case records included demographic, clinical, and treatment details.
  • Comprehensive ocular examinations were performed to diagnose PSCC and measure IOP.

Main Results:

  • Out of 82 children analyzed, 26.8% had PSCC and 10.97% had raised IOP.
  • PSCC was significantly associated with older age at recruitment (p=0.009).
  • No significant correlation was found between cumulative steroid dose (p=0.58) or duration of therapy (p=0.73) and the presence of PSCC or raised IOP.

Conclusions:

  • A notable proportion of children with nephrotic syndrome on long-term steroids develop PSCC and raised IOP.
  • Neither cumulative steroid dose nor duration of therapy showed a significant association with these ocular issues.
  • Regular ophthalmic evaluations are essential for early detection and management of steroid-induced ocular complications in this pediatric population.

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...

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...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
