Renal Corpuscle01:20

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
Cirrhosis I: Introduction01:23

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
Inflammatory Bowel Disease II: Crohn's Disease01:30

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
Chronic Kidney Disease II: Clinical Manifestations01:24

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...

Summary

Castleman disease (CD) frequently involves the kidneys, often presenting as small-vessel lesions (SVL). Loss of glomerular vascular endothelial growth factor (VEGF) in SVL correlates with CD activity.

Area of Science:

  • Nephrology
  • Hematology
  • Pathology

Background:

  • Castleman disease (CD), a lymphoproliferative disorder, presents with diverse symptoms.
  • Renal involvement in CD is rare, with limited case reports detailing various kidney diseases.

Purpose of the Study:

  • To investigate the patterns and characteristics of renal involvement in Castleman disease.
  • To explore the role of vascular endothelial growth factor (VEGF) in CD-associated kidney disease.

Main Methods:

  • Review of clinical and histological findings in 19 patients with CD and renal biopsies.
  • Immunolabeling of renal samples with anti-VEGF antibody.

Main Results:

  • Multicentric CD (89%) of plasma-cell or mixed type was common; 21% were HIV-associated.
  • Small-vessel lesions (SVL) were the most frequent renal pattern (60%) in HIV-negative patients.
  • Glomerular VEGF loss was observed in some SVL cases and correlated with C-reactive protein levels.

Conclusions:

  • Small-vessel lesions are the predominant renal manifestation in Castleman disease.
  • Loss of glomerular VEGF is linked to CD activity and may contribute to SVL pathogenesis.
