HIV-Associated Immune Complex Kidney Disease

HIV-ICKD is a type of kidney disease that occurs in some people infected with the Human Immunodeficiency Virus (HIV). It happens when the immune system produces antibodies that form complexes with antigens (foreign substances), leading to inflammation and damage in the kidneys.

Pathophysiology

Structure of the Kidneys

  • Nephrons: The functional units of the kidneys, each consisting of a glomerulus (a tiny filter) and a tubule.
  • Glomeruli: Responsible for filtering blood and forming urine.
  • Tubules: Reabsorb essential substances and excrete waste.

Blood Supply

  • The kidneys receive blood from the renal arteries, which branch off from the aorta. Blood is filtered through the glomeruli and returned via the renal veins.

Nerve Supply

  • The kidneys are supplied by the autonomic nervous system, which regulates functions such as blood flow and filtration.

Types of HIV-ICKD

  • Membranous Nephropathy: Thickening of the glomerular membrane due to immune complex deposition.
  • Focal Segmental Glomerulosclerosis (FSGS): Scarring of some parts of the glomeruli.
  • Minimal Change Disease: Changes in kidney structure that are not visible under a microscope but lead to nephrotic syndrome.

Causes of HIV-ICKD

  1. HIV infection
  2. Immune response to HIV
  3. Opportunistic infections
