Overview

Causes

According to D'Agati and colleagues[1], FSGS may be primary of secondary. Primary FSGS is defined as idiopathic FSGS, whereas secondary FSGS is defined as FSGS other etiologies.[1] The following list shows all the causes of FSGS[2]:

Primary (Idiopathic) FSGS

Secondary FSGS

Familial

  • Mutations in alpha actinin 4
  • Mutations in NPHS1 (nephrin)
  • Mutations in NPHS2 (podocin)
  • Mutations in WT-1
  • Mutations in TRPC6
  • Mutations in SCARB2 (LIMP2)
  • Mutations in INF2 (formin)
  • Mutations in CD2-associated protein
  • Mitochondrial cytopathies

Virus Associated

  • HIV
  • Parvovirus B19
  • CMV

Medication

  • Heroin
  • Interferon-alpha
  • Lithium
  • Pamidronate/aledronate
  • Anabolic steroids

Adaptive Structural-Functional Responses

Reduced Kidney Size
  • Oligomeganephronia
  • Unilateral kidney agenesis
  • Kidney dysplasia
  • Cortical necrosis
  • Reflux nephropathy
  • Surgical kidney ablation
  • Chronic allograft nephropathy
  • Any advanced kidney disease with reduction in functioning nephrons
Initially Normal Kidney Mass
  • Diabetes mellitus
  • Hypertension
  • Obesity
  • Cyanotic congenital heart disease
  • Sickle cell anemia

Malignancy

  • Lymphoma

Nonspecific Pattern of FSGS Caused by Kidney Scarring in Glomerular Disease

  • Focal proliferative glomerulonephritis
    • IgA nephropathy
    • Lupus nephritis
    • Pauci-immune focal necrotizing and crescentic glomerulonephritis
  • Alport's syndrome (hereditary nephritis)
  • Membranous nephropathy
  • Thrombotic microangiopathy
