Nonalcoholic Steatohepatitis (NASH) Overview

Nonalcoholic steatohepatitis (NASH) is liver inflammation and damage caused by a buildup of fat in the liver. It is part of a group of conditions called nonalcoholic fatty liver disease. You may be told you have a “fatty liver.” Many people have a buildup of fat in the liver, and for most people it causes no symptoms and no problems. But in some people, the fat causes inflammation and damages cells in the liver. Because of the damage, the liver doesn’t work as well as it normally should.

NASH can get worse and cause scarring of the liver, which leads to cirrhosis. But the disease doesn’t always get worse. NASH is similar to the kind of liver disease that is caused by long-term, heavy drinking. But NASH occurs in patients who don’t abuse alcohol. Patients with NASH develop progressive fibrosis in 25%-50% of individuals over 4-6 years, while 15-25% of individuals with NASH can progress to cirrhosis. In another study, 13 % of NASH patients with mild to moderate fibrosis (stage 1-2) and 50% of patients with fibrosis stage 3 developed cirrhosis.

Signs and Symptoms of Nonalcoholic Steatohepatitis (NASH)

In most early stages nonalcoholic steatohepatitis (NASH) cases, there are no noticeable symptoms. Most patients who have nonalcoholic steatohepatitis (NASH) feel fine and don’t know that they have the disease. Following are the signs and symptoms when nonalcoholic steatohepatitis (NASH) progresses and liver damage gets worse:

  • Pain in the upper right side of the abdomen
  • Fatigue (feeling tired all the time) 
  • Weight loss for no clear reason 
  • General weakness.
  • Enlarged liver or spleen (usually observed by a doctor during an exam)
  • Ascites, or swelling in the belly
  • Jaundice or yellowing of the skin and eyes

Causes of Nonalcoholic Steatohepatitis (NASH)

Exact causes of why some people with a buildup of fat in the liver get nonalcoholic steatohepatitis (NASH) and some don’t are unknown. It could be that something in the environment triggers the inflammation in these patients. It could also be a inherited disorder which runs in their families.

Things that put people at risk for nonalcoholic steatohepatitis (NASH) and for liver damage include:

  • Obesity
  • Insulin resistance and type 2 diabetes
  • High cholesterol and high triglycerides
  • Metabolic syndrome

Most patients who have nonalcoholic steatohepatitis (NASH) are 40 to 50 years old and have one or more of the problems listed above. But NASH  disease can develop in patients who have none of these risk factors.

Diagnosis of Nonalcoholic Steatohepatitis (NASH)

There is no single test that can diagnose nonalcoholic steatohepatitis (NASH). Following are some of the diagnostics tests used to see if fat is building up in the liver and to rule out other diseases:

  • Blood tests (CBC)
  • Abdominal ultrasound
  • CT scan
  • MRI scan

In addition to the above tests, a a liver biopsy may also be performed to be sure that you have NASH. In a liver biopsy, your doctor takes a sample of tissue from your liver and checks it for signs of NASH. NASH is diagnosed by the histological examination of a liver biopsy showing steatosis with concomitant inflammation and hepatocyte injury (hepatocyte ballooning).

Treatment of Nonalcoholic Steatohepatitis (NASH)

Treatment for nonalcoholic steatohepatitis (NASH) includes managing conditions that increase your risk for NASH or make it worse. You can:

  • Reduce your total cholesterol level
  • Reach a healthy weight. Losing 3% to 10% of your total body weight can make a difference
  • Control diabetes 
  • Quit Smoking
  • Stop or cut back on drinking alcohol
  • Exercise regularly

Also, consult with your doctor or pharmacist about all the medicines you are taking. Some medications may harm your liver. In some cases, your doctor may suggest medicine to control or reverse liver damage caused by nonalcoholic steatohepatitis (NASH).

Biospecimens

biospecimens

Bay Biosciences is a global leader in providing researchers with high quality, clinical grade, fully characterized human tissue samples, bio-specimens, and human bio-fluid collections.

Moreover, human biospecimens are available including tumor tissue, serum, plasma and PBMC samples from most other therapeutic areas.

Furthermore, Bay Biosciences maintains and manages its own biorepository, the human tissue bank (biobank) consisting of thousands of diseased samples (specimens) and likewise normal healthy donors for controls. Additionally, available in all formats and types.

In fact, our biobank procures and stores fully consented, de-identified and institutional review boards (IRB) approved human tissue samples, human biofluids such as serum samples, plasma samples from various diseases and matched controls.

Also, all our human tissue collections, human biospecimens and human biofluids are provided with detailed, samples associated patient’s clinical data.

In fact, this critical patient’s clinical data includes information relating to their past and current disease, treatment history, lifestyle choices, biomarkers, and genetic information.

Additionally, researchers find the patient’s data associated with the human biospecimens extremely valuable and use it to help identify new effective treatments (drug discovery & development) in oncology, as well as in other therapeutic areas and diseases.

Bay Biosciences banks wide variety of human tissue samples and human biological samples, including fresh frozen human biospecimens cryogenically preserved at – 80°C.

For example fresh frozen tissue samples, tumor tissue samples, formalin-fixed paraffin-embedded (FFPE), tissue slides, with matching human bio-fluids, whole blood and blood-derived products such as human serum, human plasma and human PBMCs.

Bay Biosciences is a global leader in collecting and providing human tissue samples according to the specified requirements and customized, tailor-made collection protocols.

Please contact us anytime to discuss your special research projects and customized human tissue sample requirements.

Types of Biospecimens

Bay Biosciences provides human tissue samples (human specimens) and human biofluids from diseased and normal healthy donors which includes:

Moreover, we can also procure most human biospecimens and human biofluids, special collections and requests for human samples that are difficult to find. All our human tissue samples and human biofluids are procured through IRB-approved clinical protocols and procedures.

In addition to the standard processing protocols, Bay Biosciences can also provide human biofluids such as  human plasma, human serum, and human PBMCs bio-fluid samples using custom processing protocols; you buy donor-specific collections in higher volumes and specified sample aliquots from us.

Bay Biosciences also provides human biospecimens from normal healthy donors; volunteers, for controls and clinical research, Contact us Now.
