Superior vena cava obstruction associated with nephrogenic systemic fibrosis
Journal of Drugs in Dermatology : JDD
|May 10, 2014
Summary
Nephrogenic Systemic Fibrosis (NSF) is a severe condition linked to gadolinium-based contrast agents (GBCAs). Skin changes can indicate dangerous internal organ fibrosis, as seen in this patient with end-stage renal disease.
Area of Science:
- Nephrology
- Dermatology
- Radiology
Background:
- Nephrogenic Systemic Fibrosis (NSF) is a debilitating fibrotic condition associated with gadolinium-based contrast agents (GBCAs).
- Patients with end-stage renal disease (ESRD) are at increased risk.
- Early recognition is crucial due to potential extracutaneous manifestations.
Observation:
- A 56-year-old woman with ESRD presented with skin thickening and discoloration.
- Cutaneous biopsy revealed increased dermal fibroblasts and CD34+ dendritic cells, consistent with NSF.
- Autopsy showed severe fibrosis of the superior vena cava (SVC) and other internal tissues.
Findings:
- The patient had received GBCAs years prior to developing NSF.
- Skin findings were indicative of widespread fibrotic disease.
- Extensive fibrosis of the SVC, dermis, subcutaneous tissue, intestines, and dura mater was confirmed post-mortem.
Implications:
- Cutaneous changes in NSF can signal life-threatening extracutaneous involvement.
- This case highlights the importance of considering GBCA exposure in patients with renal disease and fibrotic symptoms.
- Prompt recognition of skin manifestations may aid in identifying patients at risk for severe systemic NSF.

01:24Nephrotic Syndrome I : Introduction
1.2K
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...

8.2K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

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...

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration...
