Living with Immunotactoid or fibrillary glomerulopathy

Two uncommon kidney diseases, often grouped together, with blood and protein in the urine.

Understanding Immunotactoid or fibrillary glomerulopathy

Immunotactoid or fibrillary glomerulopathy covers two uncommon kidney diseases of the glomeruli (kidney filters): immunotactoid glomerulopathy and fibrillary glomerulonephritis.

Experts see them as separate but similar, and some group them together. An electron microscope can tell them apart by the size and shape of the deposits. Fibrillary glomerulonephritis is much more common. It usually begins in adulthood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Blood in the urine
  • Protein in the urine
  • Reduced kidney function
  • High blood pressure

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include kidney specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
