Abetalipoproteinemia supplements for weight: How Abetalipoproteinemia Affects the Body

Individuals with this condition may also develop an eye disorder called retinitis pigmentosa , in which breakdown of the light-sensitive layer retina at the back of the eye can cause vision loss. Furthermore, anecdotal evidence, such as the history of the two patients reported here, suggests that vitamin replacement treatment can reduce morbidity and delay early mortality associated with ABL.

In abetalipoproteinemia patients, the plasma oxidizability lag phase was The neurologic manifestations of conditions such as ataxia with vitamin E deficiency, cholestatic liver disease, and abetalipoproteinemia are thus thought to be due to a lack of circulating tocopherol, leading to inadequate protection against oxidative damage 22 Vitamin E deficiency was diagnosed. This leads to a multiple vitamin deficiency, affecting the fat-soluble vitamin Avitamin Dvitamin Eand vitamin K. Abetalipoproteinemia is caused by defects of the gene encoding the 97 kDa subunit of a microsomal triglyceride transfer protein.

Muscle involvement in ABL affecting both striated and smooth muscle has been reported in some patients, and furthermore was the cause of premature death cases among a few ABL patients [ 28 — 30 ]. However, the low serum levels of fat soluble vitamins continue, because the plasma transport and delivery of these vitamins to tissues depends almost exclusively for vitamin E and beta-carotene or in part for vitamins A, D, and K on intact synthesis and secretion of apo B-containing lipoproteins. Consequently the name of the disease was changed to ABL [ 2 ].

Retina degeneration. For instance, combined vitamin E and A therapy abetalipoproteinwmia before age 2 was reported to markedly attenuate retinal degeneration 10 years later [ 17 ]. Because pharmacologic inhibition of MTP is being developed as a novel approach to reduce plasma cholesterol for prevention of cardiovascular disease, defining the long-term clinical features of patients with a natural deficiency in MTP might provide some insight into the possible effects of such treatments.
