Silybin Phytosome to Prevent Fibrosis

Regardless of its cause, the progression of liver disease is typically measured by the suppleness, and in turn, the functionality of the liver. Recent studies demonstrate the ability of the milk thistle extract, Silybin Phytosome®, to inhibit the hardening of liver tissue.

Some types of liver disease respond well to prescribed therapy, while others take on a chronic status. In addition to addressing the underlying cause of dysfunction, these chronic liver diseases require vigilance to support liver tissue health. While each disease has a preferred conventional treatment standard, an increasing number of clinicians are predominantly concerned with fibrosis prevention.

HEPATIC

According to the Merck Manual, Fibrosis is an accumulation of fibrous tissue in the liver resulting from an imbalance between production and degradation of the extracellular matrix, and accentuated by the collapse and condensation of preexisting fibers. In more general terms, fibrosis is the hardening of liver tissue, occurring when the liver is impaired and thus, unable to break down fibrous material.

The liver is touted as the most dynamic organ in the body. This title is not only a result of the numerous functions for which it is responsible, but also for its self-restorative capability. The liver is the only organ capable of regenerating parts of itself to repair any sustained damage.

Helping maintain the liver's texture is akin to supporting this organ's health. To prevent or inhibit fibrosis, all individuals with liver disease would benefit from an accelerated regeneration of damaged liver tissue.

In Europe, silymarin, the purified extract of the fruits of S. marianum, and its main constituent, silybin, are used to maintain liver health. Worldwide, milk thistle is, deservedly, one of the most commonly prescribed medicinal plants.

S. marianum is a medicinal plant which has been widely used in traditional European medicine for centuries. Commonly known as milk thistle, St. Mary's thistle and lady's thistle, it is native to southern Europe, southern Russia, Asia Minor and North Africa. It has been naturalized to North and South America.

Literally hundreds of research studies, mostly conducted in Europe, have confirmed the remarkable ability of milk thistle to protect the liver against virtually all types of damage: from accidental exposure to chemical pollutants, toxic side effects of medications and even the self-inflicted damage from overindulgence of rich food and alcohol.

The United States National Library of Medicine has catalogued more than 300 scientific studies of milk thistle and its active compounds in their medicine database.

The active ingredients of milk thistle are not very bioavailable, especially in their purified or standardized forms. This means one would need to ingest large amounts to experience beneficial effects. Not only impractical, it could be quite expensive.

A recent study published in Digestive and Liver Disease, clearly demonstrates the ability of Silybin Phytosome® to inhibit liver fibrosis. This study confirmed Silybin Phytosome's® hepatoprotective abilities by proving it counteracts the progression of liver fibrosis typically seen in chronic liver diseases.

On a molecular level, fibrosis is marked by excessive accumulation of extracellular matrix with collagen. The hepatic stellate cells activate this cumulus. In the referenced study, Silybin Phytosome® reduced hepatic stellate cell activation and proliferation. It also significantly reduced the synthesis and deposition of collagen in liver tissue. The authors of this study concluded that Silybin Phytosome® could inhibit liver fibrosis by reducing the synthesis of collagen and by interfering with excessive accumulation of extracellular material.

Additional evidence of silybin's value in preventing fibrosis is garnered from a 1984 study demonstrating that silybin accelerates the rate of protein synthesis in the liver, leading to faster cell regeneration. A 1997 German study also reported results where silybin reduced the proliferation of hepatic stellate cells by 50 to 75 percent, which again, is highly indicative of its anti-fibrotic effect.

By their very nature, chronic liver diseases are persistent and stubborn to known modern treatments. Chronic liver disease summons our attention to provide every bit of hepatic support possible, until our medical expertise can catch up with us and ameliorate the offending disease. Years of research point to the ability of Silybin Phytosome® to meet this demand, by preventing the damage that liver diseases typically cause.

How to Prevent a Fatty Liver

Along with the increasing incidence of obesity and diabetes in Western countries, nonalcoholic fatty liver disease (NAFLD) has also become a growing problem. Although its true prevalence is unknown, some estimates suggest NAFLD may already affect as many as one-third of American adults.

NAFLD describes two conditions affecting people who drink little or no alcohol. The first is a mild condition, while the second represents its progression to a more severe disease.

STEATOSIS

1. Fatty liver, also known as steatosis, is an accumulation of fat in the liver that typically does not cause liver damage.

2. Nonalcoholic steatohepatitis (NASH) is the accumulation of fat in the liver accompanied by hepatic inflammation. Fibrous tissue can form with NASH, which can progress to cirrhosis or liver cancer.

Nonalcoholic fatty liver disease affects more women than men and is found in all age groups, including children. Nonalcoholic fatty liver disease is typically diagnosed in middle-aged people who are overweight, diabetic and who have elevated cholesterol and triglyceride levels. A person is considered to have a fatty liver when the fat makes up at least 10% of the liver.

Causes of Fatty Liver

The cause of NAFLD is unclear. The most prominent reasons for accumulation of fat in the liver are significant weight gain and diabetes mellitus. Fatty liver can also occur with poor diet and certain illnesses, such as tuberculosis, intestinal bypass surgery for obesity, and specific drugs such as corticosteroids, or heavy alcohol use. Eating fatty food by itself does not produce a fatty liver.

Possible explanations for a fatty liver include:

· The transfer of fat from other parts of the body to the liver

· An increase in the extraction of fat presented to the liver from the intestines

· The inability of the liver to transform fat into a form that can be eliminated

An increasing number of experts believe that metabolic syndrome, a cluster of disorders that increase diabetes, heart disease and stroke risk, may play a critical role in the development of NAFLD. Symptoms of metabolic syndrome include:

· Obesity - The risk of NAFLD increases with every pound of excess weight. More than 70 percent of people with NASH are obese, having a body mass index of 30 or higher.

· Hyperlipidemia -- High levels of triglycerides or low levels of high-density lipoprotein (HDL) cholesterol can cause hyperlipidemia. As many as 80 percent of people with NASH have elevated cholesterol and/or triglyceride levels.

· Diabetes - This common metabolic disorder is characterized by resistance to insulin, the hormone that regulates the amount of sugar in your blood. Recent studies have demonstrated insulin resistance to be the primary trigger for fatty liver development. Statistics show that up to 75 percent of people with NASH also have diabetes.

Understanding Insulin Resistance

A hormone released by the pancreas, insulin is dispersed into the bloodstream in response to elevated blood sugar (glucose) levels. By pushing glucose out of the bloodstream and into the body's cells, insulin keeps blood glucose levels from becoming too elevated. When these cells receive glucose, they convert it to energy. When glucose is not metabolized properly, (when the cells are insulin-resistant), energy production is diminished, resulting in fatigue.

Insulin resistance prohibits glucose from entering the cells, causing it to accumulate in the blood. In an attempt to reduce the glucose in the blood, the body signals the pancreas to produce and release more insulin. High blood insulin levels increase triglycerides, which deposit fatty acids in the liver.

Being overweight, living a sedentary lifestyle and eating a diet rich in sugar and fat all promote insulin resistance. In extreme cases of insulin resistance, diabetes mellitus develops. Approximately 70 percent of diabetics have some form of NAFLD, and 5 to 20 percent of people with diabetes have cirrhosis due to NASH. Independent of fatty liver disease, diabetes in itself is believed to be a risk factor for the development of cirrhosis.

Corrective Action

Since some estimates suggest that as many as one in four people with NAFLD may develop serious liver disease within 10 years, it is important to consider preventative and treatment options. The preferred course of action will depend on each person's fatty liver cause. Preferred methods include:

· Weight loss and exercise - A diet and exercise program will reduce the amount of accumulated fat in the liver. The most effective diet is high in fiber, vitamins and minerals, while also being low in calories and saturated fat. Safe weight loss must occur slowly, as a loss of more than two pounds a week may accelerate liver disease progression. Regardless of one's current weight, a healthy diet and daily physical activity will reduce inflammation, lower elevated liver enzyme levels and decrease insulin resistance.

· Diabetes control - Strict management of diabetes with diet, medications or insulin lowers blood sugar, which may prevent further liver damage. It may also reduce the amount of accumulated fat in the liver.

· Cholesterol control - Controlling elevated levels of cholesterol and triglycerides with diet, exercise and cholesterol-lowering medications may help stabilize or reverse nonalcoholic fatty liver disease.

· Avoid toxic substances - With NAFLD, especially the more severe version NASH, alcohol elimination is imperative. It is also important to avoid medications and other substances that can cause liver damage. Talk to your doctor about what to avoid.

· Antioxidants - Vitamins E and C, alpha-lipoic acid and N-acetyl cysteine are antioxidants that may reduce liver damage caused by oxidation, a process where unstable oxygen molecules damage cell membranes.

· Milk Thistle - Scientific studies suggest that this herb's chief constituent aids in the protection, healing and repair of the liver. With physician permission, seek a high quality, highly absorbable milk thistle for best results.

· Omega-3 fatty acids - Found primarily in cold water fish, fish oils, flax and flaxseed oils, and walnuts, omega-3 fatty acids help protect the liver and reduce inflammation.
Due to their close relationship, recovering from a fatty liver is identical to the steps necessary to combat insulin resistance A commitment to health through instituting lifestyle changes is our nation's best hope for reducing the occurrence of nonalcoholic fatty liver disease.
