Nephritic Syndrome

Nephritic Syndrome Overview:

Think I as in infection rather than O as in oedema.

Nephritic syndrome is characterised by thin basement membranes in the nephrons due to inflammation. This permits larger particles like proteins and blood into the urine. Causes can be due to either infection, thrombotic, or autoimmune conditions.

Early detection is key. Unfortuinatly it is asymptomatic iuntil significant damage has occured.


+ In Children or Adolescents

  • IgA nephropathy
  • Post-streptococcal glomerulonephritis
  • Hemolytic uremic syndrome
  • Henoch–Schönlein purpura

+ In Adults

  • Goodpasture syndrome
  • SLE
  • Rapidly progressing glomerulonephritis
  • Infective endocarditis
  • Infectious process
  • damage to the glom from AB antigen reaction
    • makes holes in the endothilial cells anbd glom becomes damaged
      • haematuria
    • glom shuts down
      • low GFR due to inflammation
      • high BP
      • Granular casts
      • oedama (not as much as nephrotic)

Diagnostic Considerations:

  • Test for kidney function every year for at risk demographics
  • Blood pressure
  • Renal function tests

Therapeutic Aims:

1. Determine And Treat The Cause

  • Diet and Medication Review (NSAIDs, Lithium, Gold, Mercury, antineoplastics, Quinine)

2. Manage Co-morbidities

Especially cardiovascular and uremic complications.

3. Reduce Inflammatory Damage In The Nephrons

  • TNF-a and NF-kB Inhibitors (Curcuma longa)
  • Flavonoid-rich Herbs (Scutellaria baicalensis, Vitis vinifera)
  • Glucocorticomimetics (Bupleurum falcatum, Rehmannia glutinosa)

4. Reduce Immune Mediated Damage

  • Immunomodulators (Astragalus membranaceus, Echinaceae purpurea, Hemidesmus indicus)

5. Tonify Renal Structure & Function

  • Renal Trophorestoratives (Solidago virgaurea, Crataeva nurvala)

6. Reduce Oedema

  • Diuretics (Solidago virgaurea, Taraxicum officinale, Asparagus officinalis, Petroselinum crispum)

7. Reduce Dysuria

  • Urinary Demulcents (Eltrygia repens, Zea mays, Althaeaofficinalis)

8. Prevent & Treat Opportunistic Urinary Tract Infection

  • Urinary Antiseptics (Juniperus communis)
  • Prevent Bacterial Adhesion (Vaccinum macrocarpon)

Differential Diagnosis:

  • Nephrotic syndrome


Rule out diabetic nephropathy.
