- which type of abnormal lipoprote in Familial hypertriglyceridemia.
- whats the processes lead to Hypertriglyceridemia
- Compare the metabolic pathway of that lipoprotein in both normal and patient with Familial hypertriglyceridemia . use a figures
- whats difference between Familial hypertriglyceridemia disease & Familial mixed hyperlipedemia
- Fibrates used as modulator for fat metabolism, explain the mechanism of action
As per Frederickson classification
Type 4 and Type 5 Hyperlipoproteinaemia with Triglyceridaemia fall
into famililial Hypertrigyceriademia
Type 3 is Familial mixed Hyperlipidaemia
Also known as Remnant removal disease and Broad B disease
Clinical features
1.Milky white plasma
2. Lipaemic retinitis
3.Eruptive xanthomas
4.Increased Triglycerides leads to pancreatitis and abdominal
pain
Fibrates as modulator for fat metabolism MOA- Act by avtivating
LPL lipoprotein lipase by activating a nuclear receptor PPAR alpha
( peroxisome propiferator activated receptor alpha).
Major effect is to reduce Trigycerides contained in VLDL very low
density lipoprotein and to increase HDL high density lipoprotein
.
Eg Fenofibrate is prodrug with longest half life .It has maximum
LDL cholesterol lowering action .Fibrates are drug of choice in
Type 3 and type 4 hyperlipoproteinaemia .
