Screening
Natural History, Complication, Prognosis
Complications
- Heart attack
- Stroke
- Peripheral vascular disease
- Intermittent claudication
- Gangrene of the lower extremities
Prognosis
- Patients with dysbetalipoproteinemia have an increased risk for coronary artery disease and peripheral vascular disease.
- With treatment, most people show a significant reduction in lipid levels.
Diagnosis
Diagnosis of dysbetalipoprotenemia is confirmed[1] by the
- Presence of a palmar crease xanthoma, which is a rare diagnostic finding of dysbetalipoproteinemia.
- Lipid profile
- Genotyping apoE
- Ultracentrifugation or nuclear magnetic resonance lipid profiling

Treatment
Medical Therapy
Dysbetalipoprotenemia is very sensitive to therapy with statins and fibrates. [2]
Prevention
- Screening the family members of those with familial dysbetalipoproteinemia may lead to early detection and treatment.
- Early treatment and avoiding other risk factors for vascular disease (such as smoking) are crucial to preventing early heart attacks, strokes, and blocked blood vessels.
