Summary
Primary amyloidosis, a systemic disease, involves protein deposits in organs. This case highlights nephrotic syndrome and severe factor X deficiency, showing a good response to chemotherapy.
Area of Science:
- Nephrology
- Hematology
- Pathology
Background:
- Amyloidosis is a systemic disease defined by beta-organized protein fibril deposition in organs like the kidney, liver, and heart.
- Primary (AL) amyloidosis, the most common form, results from monoclonal light chain fragment deposition.
- Associated Factor X deficiency can occur due to amyloid fibril adsorption.
Observation:
- A case of primary amyloidosis presented with nephrotic syndrome and severe factor X deficiency.
- The patient experienced no bleeding complications despite the coagulation disorder.
- Potential cardiac involvement was also noted.
Findings:
- Biopsy confirmed amyloid deposition.
- Severe factor X deficiency was quantified.
- The patient showed a positive short-term response to chemotherapy.
Implications:
- This case underscores the complex clinical manifestations of primary amyloidosis.
- It highlights the potential for significant coagulation factor deficiency without overt bleeding.
- Early chemotherapy may offer a favorable short-term prognosis in select primary amyloidosis cases.
