- Metabolic syndrome, type 2 diabetes and obesity are risk factors for the development of liver fibrosis and steatosis liver fat accumulation in people living with HIV, including those who do not have viral hepatitis co-infection, according to research presented at the 9th International AIDS Society Conference on HIV Science IAS last month in Paris.
Fatty liver disease occurs when triglycerides and other fats build up in the liver, which can cause inflammation and interfere with normal liver function.
The condition often develops in people who are overweight or obese. It is now one of the leading causes of serious liver disease worldwide. Fat accumulation in liver cells is known as steatosis. Fatty liver is a common consequence of heavy drinking. When it occurs in people who drink little or no alcohol, its milder form is known as non-alcoholic fatty liver disease NALFD and its more severe form is non-alcoholic steatohepatitis NASH.
Located on the right side of the abdomen behind the ribcage, the liver carries out many vital functions. These include filtering the blood, helping convert food into energy, processing medications and producing proteins that help the blood clot after an injury. Over time, fat accumulation in liver cells can lead to inflammation and progressive liver damage.
This can include:. Fibrosis — build-up of collagen and other fibrous scar tissue, leading to a 'stiff' liver. Cirrhosis — serious scarring that blocks blood flow through the liver and interferes with liver function. End-stage liver disease — severe loss of liver function that can result in death without a liver transplant.
Liver fat build-up is linked to being overweight and having a cluster of metabolic problems like high blood fat levels and type 2 diabetes known as metabolic syndrome. Changes to your lifestyle can lower your risk of developing fatty liver disease.
The same lifestyle changes can help reduce the amount of fat in your liver if you already have it. An essential organ involved in digestion of food and excretion of waste products from the body. Non-alcoholic fatty liver disease NAFLD is a very common disorder and refers to a group of conditions where there is accumulation of excess fat in the liver of people who drink little or no alcohol. The most common form of NAFLD is a non-serious condition called fatty liver, by which fat accumulates in the liver cells.
In NASH, fat accumulation is associated with liver cell inflammation and different degrees of scarring. NASH is a potentially serious condition that may lead to severe liver scarring and cirrhosis. It sometimes affects older people living with HIV.
Any perceptible, subjective change in the body or its functions that signals the presence of a disease or condition, as reported by the patient. Lose weight. Maintaining a healthy weight can keep you from getting fatty liver disease. You should aim to keep your weight within the ideal range for your height, age and sex. Your doctor, nurse or dietitian can tell you what this range is. Weight loss is best achieved by both reducing calories and increasingly physical activity.
Exercise regularly. Moderate activity includes brisk walking, dancing, gardening and cycling. In addition to exercising at home or at the gym, try to increase the amount of physical activity in your daily routine. For example, increase the amount you walk by parking your car further away from shops or getting off the bus a couple of stops early.
Eat a healthy, balanced diet. Replace red meat with other protein sources such as chicken, fish and beans. Limit foods and drinks that are high in fat and refined sugar. This may be easier if you plan your meals around vegetables rather than meat, rice or pasta.
A dietitian at your GP or HIV clinic can help you find a diet that will suit the way you live and the foods you like to eat. Drink less alcohol. Alcohol can cause severe liver damage including fat build-up and scarring. This usually happens after years of heavy drinking, but binge drinking drinking a lot on a single occasion can also harm your liver.
Experts recommend that men and women should drink no more than 14 units of alcohol a week. Fatty liver disease is becoming more common as the number of people who are overweight rises. As many as one in five people in the UK may have fatty liver disease. The more overweight you are — especially if you have excess fat around the waistline — the greater your risk of having fatty liver disease. If you have conditions that make up metabolic syndrome, including high cholesterol and triglyceride levels, high blood pressure and insulin resistance or type 2 diabetes, you are more likely to develop fatty liver disease.
Because it develops slowly, fatty liver disease is most often seen in people aged 40 or older. People with hepatitis B or hepatitis C are more likely to develop fatty liver disease. Some medications can cause fatty liver as a side-effect. It is also caused by some genetic conditions and can run in families. Fatty liver disease has not been as extensively studied as other causes of liver disease in people living with HIV. The main risk factors were being overweight and having conditions related to metabolic syndrome.
Fatty liver disease is even more common in HIV-positive people who have hepatitis C co-infection. Some older HIV medications, including zidovudine Retrovir and stavudine Zerit , could cause serious steatosis and liver enlargement as a side-effect related to mitochondrial toxicity.
This is generally not a concern with modern anti-HIV drugs. However, some studies suggest that efavirenz Sustiva, also included in the Atripla combination pill may be more associated with fatty liver disease than other drugs.
Most people do not have symptoms during the early stages of fatty liver disease. The condition progresses over time as working liver cells become filled with fat. Many people never develop serious liver complications, but in some cases the liver can stop working properly. People with advanced liver damage are at greater risk for developing liver cancer.
Early symptoms of impaired liver function can include fatigue unusual tiredness , flu-like symptoms, loss of appetite, pain or swelling in the upper abdomen and jaundice yellowing of the skin and eyes. As liver damage worsens, people can develop more severe symptoms including ascites fluid build-up in the abdomen , bleeding in the throat or stomach and mental confusion hepatic encephalopathy.
Fatty liver disease may be detected through liver function tests that are routinely done at your HIV clinic. These blood tests, including the ALT test, measure proteins associated with liver inflammation. But results are often normal or only slightly elevated in people with fatty liver disease. The most accurate way to diagnose fatty liver disease is a liver biopsy, in which a small sample of liver tissue is removed for lab testing.
However, many different experimental therapies are currently being tested in clinical trials. Weight loss is the mainstay of fatty liver management, along with treatment of related conditions such as diabetes and elevated blood fat levels.
This also reduces the risk of cardiovascular disease, which is a leading cause of death for people with fatty liver disease. It may be necessary to lose a substantial amount of weight before liver damage improves, but any weight loss is beneficial.
Alcohol-related fatty liver disease usually improves when people stop drinking. People with fatty liver disease should receive the hepatitis A and hepatitis B vaccines, because these viruses can cause more liver serious damage in people with existing liver disease.

Liver Steatosis and Stiffness in HIV The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. A quarter of people with metabolic syndrome had moderate fibrosis, compared with about 7 percent of those without. People with moderate or worse fibrosis had significantly higher levels of inflammatory markers than those with absent or mild fibrosis stage F0 or F1 , including C-reactive protein, interleukin 6, leptin and adiponectin two hormones produced by adipose or fat tissue and a marker linked to macrophage activation a type of immune system white blood cell. They had been on ART for a median of seven years, and many of them had used older antiretrovirals that can cause metabolic or liver-related side effects. Severe fibrosis, or scarring of organs. Over time, these progressive conditions can lead to liver function impairment, liver cancer and the need for a liver transplant.

And hazardous consumption of alcohol, compared with a lack of hazardous usage, was linked to 73 percent increased risk of steatosis. Our study group was coinfected with HIV, and we did not exclude individuals who used drugs or those who had been treated, whether cured or not, for HCV. Because they did not follow the study cohort over time, they could not analyze how cannabis may be associated with the development or evolution of fatty liver disease.
Additionally, the study cannot rule out that steatosis led to greater use of cannabis. The study could also not parse its data to determine how short- versus long-term use of pot may be differently associated with steatosis risk.

When the liver tests have returned to normal HIV drugs might be restarted. This is often with a different combination of drugs or reduced doses. The risk of nevirapine-related liver toxicity is different between men and women. This risk is related to CD4 count when starting treatment. These CD4 upper limits are not thought important if you already have an undetectable viral load and are switching one of your current drugs to nevirapine.
They do not relate to pregnant women who are using a single dose of nevirapine as part of treatment to reduce the risk of transmitting HIV to their baby.
Close monitoring every two weeks in the first two months of therapy is recommended for anyone who starts a nevirapine-based combination. This is when liver problems first start to occur. Liver toxicity might also build up slowly and so routine monitoring after the first two months is also important.
Only if you have none of the symptoms listed below and your liver function tests are within the acceptable levels can you increase your nevirapine dose to one tablet mg twice a day. Blood samples should be taken every two weeks in the first two months to check liver function, then at the end of the third month, and then every three to four months if they are within normal limits. During this first eight weeks you should contact your doctor straight away if you have any of the following symptoms:.
If the results are not higher than twice the normal limit, and depending on the severity of your symptoms, a decision will be made whether or not to continue with nevirapine. If a decision is made to continue, you will be very closely monitored to ensure that the symptoms do not progress or your liver function tests get worse.
If your liver tests get to five times the normal limit or mild symptoms get worse, then your nevirapine must be stopped. Your doctor will recommend whether you need to stop all your treatments or just switch the nevirapine to another drug. If you stop nevirapine for these reasons, you must not take it again in the future. This build-up of fat in the liver can affect the way it processes fats.
Hepatic steatosis often also leads to lactic acidosis. People who weigh over 70 kgs, especially women, might be more at risk of developing hepatic steatosis and lactic acidosis. Ultrasonography is a sensitive, accurate, non-invasive screening tool to detect steatosis as this is not always shown in liver function tests. Steatosis is also common in HIV-positive children.

Liver disease is a major cause of morbidity and mortality among people living with HIV. Hepatitis B or C virus HBV or HCV , heavy alcohol consumption, certain antiretroviral medications and other causes of liver injury can lead to the development of liver fibrosis, cirrhosis and steatosis.
But these can also occur without such liver-specific risk factors. Fatty liver disease, associated with metabolic syndrome, is a growing problem as the population becomes more obese. Over time, non-alcoholic fatty liver disease NAFLD and its more advanced stage, non-alcoholic steatohepatitis NASH , can lead to liver function impairment, liver cancer and the need for a liver transplant.
Body mass index, or BMI, is a measure of body size. It combines a person's weight with their height. The BMI gives an idea of whether a person has the correct weight for their height. Many BMI calculators can be found on the internet. The physical and chemical reactions that produce energy for the body. Metabolism also refers to the breakdown of drugs or other substances within the body, which may occur during digestion or elimination.
Non-alcoholic fatty liver disease NAFLD is a very common disorder and refers to a group of conditions where there is accumulation of excess fat in the liver of people who drink little or no alcohol. The most common form of NAFLD is a non-serious condition called fatty liver, by which fat accumulates in the liver cells.
Fat or fat-like substances found in the blood and body tissues. Lipids serve as building blocks for cells and as a source of energy for the body. Cholesterol and triglycerides are types of lipids.
A group of symptoms and diseases that together are characteristic of a specific condition. The median body mass index BMI was Although they were approximately matched based on demographic characteristics and metabolic factors, there were some significant differences. For each participant, the researchers calculated a Fatty Liver Index FLI score based on laboratory and physical exam findings including triglyceride and gamma-glutamyl-transferase GGT liver enzyme levels, BMI and waist circumference.
Liver steatosis was defined as an FLI of 60 or higher. HIV infection was an independent risk factor, doubling the likelihood of having fatty liver, Perazzo reported. HIV-positive people with steatosis were, on average, older, had higher BMI and waist circumference, had a higher CD4 count and had been on antiretroviral therapy ART longer than those without.
There were no significant differences related to nadir lowest-ever CD4 count, current ART regimen or current viral suppression. In a multivariate analysis, independent risk factors for fatty liver were HIV infection odds ratio 2.
In addition, higher CD4 count OR 1. They recommended that management of metabolic risk factors should be integrated into HIV care to decrease the burden of liver diseases in this population. In response to a question, Perazzo said that FibroScan , an imaging method for assessing fibrosis and steatosis, was not available at the time of the study.
Session moderator Marina Klein of McGill University in Montreal noted that researchers are looking for more accurate non-invasive biomarkers of fatty liver as it becomes a more prevalent cause of serious liver disease in people with and without HIV. Perazzo H et al. HIV infection is an independent risk factor for liver steatosis: A study in HIV mono-infected patients compared to uninfected paired controls and associated risk factors.
