Acute Kidney Injury II: Pathophysiology01:29

Acute Kidney Injury II: Pathophysiology

1.3K
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...

Imaging Studies VII: Vascular Imaging

399
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

1.3K
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Rheumatic Heart Disease I: Introduction

599
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Endocarditis II: Clinical Features of Infective Endocarditis

589
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...

Renal Corpuscle01:20

Renal Corpuscle

7.8K
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...

Area of Science:

  • Nephrology
  • Rheumatology
  • Immunology

Background:

  • Historical classification of systemic vasculitis involved distinct disease entities.
  • Recent trends in renal vasculitis favor a
  • lumping
  • approach, recognizing overlap between conditions like microscopic polyarteritis, crescentic glomerulonephritis, and Wegener's granulomatosis.

Purpose of the Study:

  • To review the evolving classification and therapeutic strategies for renal vasculitis.
  • To highlight the role of antineutrophil cytoplasmic antibodies (ANCA) in understanding commonalities among renal vasculitides.
  • To summarize current treatment outcomes for ANCA-associated renal vasculitis.

Main Methods:

  • Review of medical literature on systemic and renal vasculitis.
  • Analysis of therapeutic approaches, including induction and maintenance therapies.
  • Evaluation of patient and kidney survival rates.

Main Results:

  • Antineutrophil cytoplasmic antibodies (ANCA) provide evidence for commonality among various renal vasculitides.
  • Methylprednisolone and cyclophosphamide are standard induction therapies for severe glomerulonephritis.
  • Adjunctive plasma exchange shows limited efficacy; maintenance therapy often involves azathioprine or pulsed cyclophosphamide.

Conclusions:

  • Contemporary management of ANCA-associated renal vasculitis has shifted towards recognizing disease overlap.
  • Effective induction and maintenance therapies contribute to improved patient and kidney survival.
  • Five-year survival rates for ANCA-associated renal vasculitis range from 60% to 80%.
