Oral Anabolic Steroids, Liver Enzyme Tests and Liver Function
Ann Intern Med ; What Is Ulcerative Colitis? Bratisl Lek Listy ; Liver tumours and steroid hormones. All oral steroids are somewhat "liver toxic" or burden the liver in a dose-related manner, and my experience is that the actual toxicity is somewhat exaggerated.
In AAS users the obstruction may be due to the prolapse of hyperplasic hepatocytes into the hepatic venule wall. Recognize These Common Eye Conditions. Jaundice associated with norethindrone acetate therapy. In contrast, the esterified testosterones have only rarely been implicated in causing cholestasis, although their long term use may increase the risk of hepatic tumors and nodular transformation, but seemingly at a much lower rate than the alkylated testosterones. After all, steroids can have many bad influences on our organism, but when you decide to start taking them, you should know what the risks are.
An intravenous infusion of estradiol glucuronide, testosteroneglucuronide or dihydrotestosteroneglucuronide would cause cholestasis just as oral methyltestosterone or ethinylestradiol does. So what about the supposedly liver friendly oxandrolone? The following excerpt summarizes why it is liver friendly: Unlike other orally administered C17alpha-alkylated AASs, the novel chemical configuration of oxandrolone confers a resistance to liver metabolism as well as marked anabolic activity.
In addition, oxandrolone appears not to exhibit the serious hepatotoxic effects jaundice, cholestatic hepatitis, peliosis hepatis, hyperplasias and neoplasms attributed to the C17alpha-alkylated AASs.
I submit that its resistance to metabolism glucuronidation is the reason for its lack of toxicity. So we now know glucuronides are to blame for liver toxicity. Now let's examine how they cause cholestasis. Bile flow is regulated in two ways; bile salt independent flow, and bile salt dependent flow. Bile salt independent flow is a passive process controlled mainly by the osmotic factors glutathione and bicarbonate. The exact mechanisms are not known, but it is known that biliary glutathione levels decrease significantly soon after a toxic steroid is administered.
The total hepatic glutathione increases, which seems to indicate that glutathione transport to the bile duct becomes impaired. Bicarbonate transport to the bile is similarly impaired, but it is not due to impaired transporters, rather the gradient becomes diminished by some type of bicarbonate reuptake.
These processes occur rapidly and are the first toxicities observed. Bile salt dependent flow is an active process that is controlled by numerous membrane bound transporters.
Specifically ATP bind cassette ABC transporters transport the bile salts from the blood into the hepatocyte basolateral , and then from the hepatocyte to the bile canilicular. The pumping of bile salts into the bile is the main force that drives bile flow, which is what we want for normal functioning. Although both basolateral and canilicular transporters are probably involved in hormone induced cholestasis, the most examined is the canilicular bile salt export pump BSEP.
Oral steroid glucuronides are known to interact with the promoter region of the gene for this transporter and to repress its expression. Besides repression of the gene, other factors may decrease the BSEP function as well. The transport of the BSEP from its point of synthesis to the canilicular membrane can be impaired in cholestasis, providing functional transporters in the wrong place within the cell.
Finally there is the genetic component. There is a great deal of genetic variation in ABC transporters among the population. Certain people are at a higher risk for developing cholestasis than others, and in the near future it will be possible for you to determine what genetic polymorphisms you have in your hepatic transporters. This should be very valuable information for anyone who is planning on taking a potentially liver toxic drug, whatever it may be.
In the meantime, the best method for determining if you are at risk for cholestatic problems is to look to your family. Cholestatic conditions to be mindful of are cholestasis of pregnancy, progressive familial intrahepatic cholestasis, benign recurrent intrahepatic cholestasis, and Dubin-Johnson syndrome.
Having close relatives which any of these conditions possibly puts you at a greater risk of having toxicity issues with oral AAS. Sulphasalazine, a cheap drug currently used for arthritis and IBD inflammatory bowel disease can reverse the scarring that comes with cirrhosis of the liver, say scientists from the University of Newcastle, UK.
Doctors had always thought that fibrosis - scarring associated with cirrhosis - was irreversible. This new study on animals has shown the damage can be reversed with Sulphasalazine.
The liver has hepatic myofibrobrlasts, these are cells that create scar tissue when the organ is injured. Hepatic myofibrobrlasts produce proteins which makes it more difficult to break down the scar tissue. In a healthy liver the scars gradually disappear and new healthy ones replace them.
This does not happen when the liver tissue is diseased - and the scar tissue spreads. The scientists found that Sulphasalazine stops the hepatic myofibrobrlasts from producing the protein that protects the scar tissue cells.
In other words, it helps the scar tissue to gradually melt away. If human trials show similar results, it could mean treating and-stage patients with Sulphasalazine rather than having them undergo a liver transplant. The scientists say they will start trials with heavy drinkers who no longer drink, but whose livers are not able to recover on their own.
This drug could be a Godsend for alcoholics who have given up drinking. The researchers say Sulphasalazine could halve the cirrhosis death rate in the UK. Some Facts About Cirrhosis -- Responsible for 1. The only end-stage treatment is a liver transplant -- Most common causes are Hepatitis C globally and excessive alcohol consumption developed countries -- Scotland has particularly high rates among developed countries. The medicine, found by a team of doctors and scientists at Newcastle University, could become a potential alternative to liver transplants.
Until now cirrhosis of the liver, caused by alcohol, obesity or the hepatitis C virus, was considered incurable in all but the rarest of cases. The only option for patients in the final stages of liver disease was to wait for a liver transplant. However, because of organ shortages many die while on the waiting list.
Clinical trials of the drug Sulphasalazine are expected to begin in Britain next year. If these prove successful, the drug could be used to treat heavy drinkers, whose plight was recently illustrated by George Best, the former Manchester United footballer who died from liver disease last year. Sulphasalazine, which already has a licence to treat arthritis and inflammatory bowel disease, acts by preventing scarring from developing on the liver. Tests carried out in the laboratory and on animals have shown that the medication can even reverse damage already inflicted on the liver.
The drug will initially be given to heavy drinkers who have given up alcohol, but too late for their liver to recover naturally. If this proves successful, the medicine will also be prescribed to alcoholics who continue to drink but show a determination to fight their addiction by reducing their intake. Even though we remove the cause of the liver scarring, by this stage that is not enough.
I would be of the view that it should be tried in patients who are making an effort. The decision to give Best a liver transplant was controversial because the late footballer continued drinking. Critics argued that the organ should have been given to someone whose illness was not self-inflicted. If the drug is not prohibitively expensive, it could be given to all liver disease patients, regardless of whether the damage had been caused by a congenital disorder or years of alcohol abuse. After years of heavy drinking or obesity, so many scars appear on the liver that it can no longer carry out its normal tasks such as storing essential proteins and vitamins while cleaning up toxic substances.
The new use for the drug followed the discovery by Professor Derek Mann, a member of the team at Newcastle University, who identified the cells and proteins that may move the liver disease into reverse. Submitted by RonnyT on Thu, Anabolic Oral Steroids and the Liver Liver damage is probably the most sensationalized of all possible side effects from oral steroid use. Elevated liver enzymes Regarding elevations of SGOT, and SGPT; let's note that the liver is basically a "factory" that manufactures things like proteins and processes or destroys things like medications.
For this reason alone, it would be quite irresponsible for any athlete to use anabolic steroids without having a physician regularly conduct blood tests to monitor liver function But the most important consideration here that we should underline is that the relative "liver toxicity" of anabolic steroids that are injectable and oil-based is generally not a major consideration, because these compounds are basically metabolized the same as the natural testosterone that is already in the body.
Scientific Studies A computer search of the medical literature looking for steroid-associated liver tumors could find only three in athletes Friedl, In this study the researchers used the following drugs and dosages: A little insight about relative toxicity All oral steroids have a chemical bond that must be broken before the drug becomes bioavailable. Liver Anatomy and Function The liver has numerous important functions in the body, but its relevant functions for this article include drug metabolism and excretion, and secretion of bile salts and bicarbonate for digestion.
The only end-stage treatment is a liver transplant -- Most common causes are Hepatitis C globally and excessive alcohol consumption developed countries -- Scotland has particularly high rates among developed countries The medicine, found by a team of doctors and scientists at Newcastle University, could become a potential alternative to liver transplants.

This is just a short list, but this should be enough to make you realize how important that organ really is and how important it is for you want to maintain proper liver function for maximum health.
There are many things are known to harm the liver, including excessive alcohol intake and drug use. From an athletic point of view, certain types of anabolic steroids are frequently mentioned as having bad effects on liver function, such as oral drugs that are classified as alpha alkylated drugs.
Scientists developed the testosterone derivatives after noting that orally taken testosterone is degraded in the liver in a process called first-pass metabolism. Drug developers circumvented that formidable problem by making testosterone available in an injectable form as this bypasses initial first-pass liver metabolism, and by manipulating the basic steroid chemical structure, as is the case with oral alpha alkylated anabolic steroids.
While the structural change in oral anabolic steroids did result in a far slower rate of breakdown in the liver, it also led to an inordinate buildup of such drugs in the liver. Since the injectable versions of steroids do not build up in the liver as much as oral versions, the injectables are considered less of a problem in terms of normal liver function. The oral drugs adversely affect the liver through several mechanisms. To start with, they interfere with the function of certain liver enzymes as anabolic steroids are known to increase the activity of some liver enzymes while downgrading that of others.
A lowered HDL level is considered a risk factor for cardiovascular disease. Athletes who use oral anabolic steroids nearly always show depressed HDL levels as the buildup of alpha alkylated oral anabolic steroids in the liver leads to a type of toxic or chemical hepatitis. Hepatitis is a general word for an inflammation of the liver and can be caused by various factors, such as drug use and viruses.
But, after taking a longer break, when you do the test again, you may find yourself in a situation where liver enzymes are still higher than normal. There are two main liver enzymes that show us what condition the liver is in. This is very useful in revealing certain diseases like hepatitis. But, these are not the only tests done, there are a few more, and every one of them reveals different damages and different causes of those damages. Why is liver damage a serious thing?
Liver has a really big role in our organism. But, the food we eat, the fluids we drink, the medicines we take, all of these things have a big influence on our liver condition. Steroid usage also leaves a mark on it. Steroids can stay in our body and blood system long after we finish the cycle. If you take them intravenously you can find traces of them even months after stopping the usage. This is why oral steroids are more popular, because it is estimated that they will stay in our organism only for a few weeks.
This is also a long period, but when you compare it to intravenously taken steroids, it looks short. Higher level of liver enzymes If you are in the situation where you have increased levels of liver enzymes, you should definitely contact your doctor for further analysis.
There are many types of steroids, some of them are similar to others, but differences are something that is normal. Different steroids have a different influence on our organism ; they have different usage, different cycle treatment, and also, the estimated time for staying in our organism is also different. But, you need to know that the most reliable way to find out the cause of higher levels of these enzymes is liver pathology which gives the best results.
It will show the type of damage, its origin and how dangerous it is.

Another thing to remember is that these enzymes will rise when almost any drug is taken by the patient. There are two main liver enzymes that show us what condition the liver is in. This is evidenced by the fact that more than a third of the compound is still intact when excreted in the urine.
The researchers say Sulphasalazine could halve the cirrhosis death rate in the UK. The syndrome is similar to cholestasis of pregnancy and the jaundice associated with high doses of estrogens or birth control pills and may be due to partial lack or variant of bile salt transporter proteins.
If you take them intravenously you can find traces of them even months after stopping the usage. Side effects of testosterone treatment include:. Beware of Diabetes Foot Dangers. About Ella Building muscle is what i like to talk about. So it's not that these steroids are harder to metabolize, but rather the way oral anabolic steroids liver are metabolized causes them anavar first effects be toxic.
