Blood work and liver functioning

[hoping4better]

Hi all,
I don't post often but I am following the Sinclair Method and interested in adding the baclofen (but not sure it would cancel out the naltroxene). I just want to get enough arsenol to battle this addicition.

My question really has nothing to do with these methods, really, but with blood tests for the nal and another drug. My psych wants to add Abilify to my Wellbutrin rx -- which I'm not sure I am in favor of after a web search on the med -- but I need to have complete bloodwork done first. I haven't had a liver function test in yrs so I am nervous. What if my liver is totally shot? I guess I'm scared to hear the result. I'm an everyday drinker, about a bottle ofwine per night and sometimes more. I can't imagine my liver function to be anywhere near normal.

Has anyone else had this test and been "normal?" Thanks!

My blood work has been normal in recent tests. Even if it is not, wouldn't it be better to know? There are things you can do to help, like take milk thistle.

I have my blood work tomorrow. Two weeks ago was a bottle of wine a day drinker. Had 11 of 14 days AF since then, taking milk thistle folic acid magnesium morning primrose oil multivitamin calcium citrate and drinking lots of lemon juice. We'll see how it goes. I read that you have to be AF for at least 10 days for some of the enzyme-related tests to come back normal.
I agree, better to know than not...

I know people through AA that were given 6 months to live because their livers were so shot. Now many years later they are sober and alive and kicking. Nothing they can tell you cannot get better once you stop. Anything you can do to stop now will help.

To be honest a simple blood liver function test (in my opinion) is not an accurate account of the reality of how your liver is doing. My fathers liver function tests always come back in the normal range even though his liver is so swollen he looks pregnant.

I have had liver function blood tests come back normal and then gone to a naturopath who does other tests and have had impaired functioning (after about 10 days of not drinking the naturopaths tests always lower and come back in the more normal range - the livers ability to repair itself is amazing).

Not trying to scare you but I just don't think the simple blood test of liver functionality alone should be what we all live by - it's not the most accurate representation of how our body is doing. I agree with everyone above - Milk Thistle, and anther vitamin called Lecithen (as well as Liv 52) and abstainment - we can reapair ourselves.

Just my 2 cents.

So can I still drink if I take milk thistle? Just kidding.
I went to have my blood test yesterday, coupled with a mamogram, what a fun combo! But the lab was already closed. So I went to another lab only to have them tell me I have to come in the morning, WITHOUT COFFEE!!!!! fasting, for the test. Like I'm going to find that easy to do with two kids in tow. I sure with my doctor had told me it was a morning test or I would have done it when DH was here and could stay with the kids until I got back.
grrrrrrr.....

Thanks Cacky, but I didn't go. One - could not bear a morning without coffee. Two - didn't want to drag kids there at 7:30. Three - drank a bottle of wine last night (ooooooooops). Four - leave for London today. So I ducked it. Not proud of it.

Blood work and liver functioning

One of the reasons why I am not a fan of moderation or continued drinking is that many of the people here have damaged livers. About 20% of heavy drinkers have cirrhosis of the liver. There really is no way to be definitive without doing a liver biopsy. A person can have normal LFTs (liver function tests) and have a pickled liver. It can be seen on ultrasound as a bright shiny reflective liver due to scarring and fibrosis. MRI and Ct scans can also pick this up but a biopsy is the gold standard.
Meaning you can have normal LFTs and have put your liver through the wringer.
If you look at a liver at autopsy of a drinker versus that of a nondrinker. It's quite striking the difference in texture. While alive, both may have had normal LFTs
On the other hand, the liver is quite a forgiving organ so its not the end of the world and can abnormal LFTs can be temporary. One of the reasons I have chosen to never drink again is that I have damaged my liver so moderation or occasional drinking will cut my life short for certain having almost been in liver failure and in the ICU. I would think that would be one reason why many should not consider drinking occasionally after drinking so heavily. So people need to gauge the level of their drinking and possible liver damage. This cant be done via the internet or with a liver function test alone. You can have a non-scarred liver and abnormal LFT's and you can have a very fibrotic, scarred liver with normal LFTs. If you have been a very heavy drinker for some time. No doubt that the liver has changed, the only thing can be done to treat it is to no longer subject it to alcohol use to prevent further damage. Abstaining for long periods of time, the so called "liver holiday" is better than nothing and some physicians recommend that to alcoholics. Although this is stop-gap measure as repeated abuses of the liver will inevitably occur and lead to health problems or even early death in a percentage of alcoholics. Liver cirrhosis is the 12th leading cause of death in the USA. Also alcoholics should NEVER take tylenol, acetaminophen or as they call it in australia paracemetol.
I will post more definitive discussion regarding this issue as it will explain things more than I have the time to do:
Special Considerations in Interpreting Liver Function Tests

A number of pitfalls can be encountered in the interpretation of common blood liver function tests. These tests can be normal in patients with chronic hepatitis or cirrhosis. The normal range for aminotransferase levels is slightly higher in males, nonwhites and obese persons. Severe alcoholic hepatitis is sometimes confused with cholecystitis or cholangitis. Conversely, patients who present soon after passing common bile duct stones can be misdiagnosed with acute hepatitis because aminotransferase levels often rise immediately, but alkaline phosphatase and gamma-glutamyltransferase levels do not become elevated for several days. Asymptomatic patients with isolated, mild elevation of either the unconjugated bilirubin or the gamma-glutamyltransferase value usually do not have liver disease and generally do not require extensive evaluation. Overall hepatic function can be assessed by applying the values for albumin, bilirubin and prothrombin time in the modified Child-Turcotte grading system.

The commonly used liver function tests (LFTs) primarily assess liver injury rather than hepatic function. Indeed, these blood tests may reflect problems arising outside the liver, such as hemolysis (elevated bilirubin level) or bone disease (elevated alkaline phosphatase [AP] level).

Abnormal LFTs often, but not always, indicate that something is wrong with the liver, and they can provide clues to the nature of the problem. However, normal LFTs do not always mean that the liver is normal. Patients with cirrhosis and bleeding esophageal varices can have normal LFTs. Of the routine LFTs, only serum albumin, bilirubin and prothrombin time (PT) provide useful information on how well the liver is functioning.

The general subject of LFTs1,2 and the differential diagnosis of abnormal LFTs in asymptomatic patients3-5 have been well reviewed. This article discusses some common pitfalls in the interpretation of LFTs. Hints for interpreting these tests are presented in Table 1.

TABLE 1
Helpful Hints for Interpreting Liver Function Tests
Situation
Mildly elevated ALT level (less than 1.5 times normal) ALT value could be normal for gender, ethnicity or body mass index.
Consider muscle injury or myopathy.
Alcoholic hepatitis Laboratory values can appear cholestatic, and symptoms can mimic cholecystitis.
Minimal elevations of AST and ALT often occur.
AST level greater than 500 U per L The AST elevation is unlikely to result from alcohol intake alone.
In a heavy drinker, consider acetaminophen toxicity.
Common bile duct stone Condition can simulate acute hepatitis.
AST and ALT become elevated immediately, but elevation of AP and GGT is delayed.
Isolated elevation of GGT level This situation may be induced by alcohol and aromatic medications, usually with no actual liver disease.
Isolated elevation of AP level (asymptomatic patient with normal GGT level) Consider bone growth or injury, or primary biliary cirrhosis.
AP level rises in late pregnancy.
Isolated elevation of unconjugated bilirubin level Consider Gilbert syndrome or hemolysis.
Low albumin level Low albumin is most often caused by acute or chronic inflammation, urinary loss, severe malnutrition or liver disease; it is sometimes caused by gastrointestinal loss (e.g., colitis or some uncommon small bowel disease).
Normal values are lower in pregnancy.
Blood ammonia level Blood ammonia values are not necessarily elevated in patients with hepatic encephalopathy.
Determination of blood ammonia levels is most useful in patients with altered mental status of new onset or unknown origin.
ALT=alanine aminotransferase; AST=aspartate aminotransferase; AP=alkaline phosphatase; GGT=gamma-glutamyltransferase.

Markers of Hepatocellular Injury

The most commonly used markers of hepatocyte injury are aspartate aminotransferase (AST, formerly serum glutamic-oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT, formerly serum glutamate-pyruvate transaminase [SGPT]). While ALT is cytosolic, AST has both cytosolic and mitochondrial forms.

Hepatocyte necrosis in acute hepatitis, toxic injury or ischemic injury results in the leakage of enzymes into the circulation. However, in chronic liver diseases such as hepatitis C and cirrhosis, the serum ALT level correlates only moderately well with liver inflammation. In hepatitis C, liver cell death occurs by apoptosis (programmed cell death) as well as by necrosis. Hepatocytes dying by apoptosis presumably synthesize less AST and ALT as they wither away. This probably explains why at least one third of patients infected with hepatitis C virus have persistently normal serum ALT levels despite the presence of inflammation on liver biopsy.6,7 Patients with cirrhosis often have normal or only slightly elevated serum AST and ALT levels. Thus, AST and ALT lack some sensitivity in detecting chronic liver injury. Of course, AST and ALT levels tend to be higher in cirrhotic patients with continuing inflammation or necrosis than in those without continuing liver injury.

Typical ALT or AST Distribution
Figure 1
{short description of image}

FIGURE 1. Typical population distribution of serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels. The population distributions for these aminotransferases do not follow a bell-shaped curve but are skewed, with a long "tail" at higher values. By convention, values above the 97.5th percentile are considered elevated (shaded area). Although average values for ALT and AST are similar in different populations, the distributions are more skewed in males and in nonwhite ethnic groups (i.e., blacks and Hispanics).

As markers of hepatocellular injury, AST and ALT also lack some specificity because they are found in skeletal muscle. Levels of these aminotransferases can rise to several times normal after severe muscular exertion or other muscle injury, as in polymyositis,8 or in the presence of hypothyroidism, which can cause mild muscle injury and the release of aminotransferases. In fact, AST and ALT were once used in the diagnosis of myocardial infarction.

Slight AST or ALT elevations (within 1.5 times the upper limits of normal) do not necessarily indicate liver disease. Part of this ambiguity has to do with the fact that unlike the values in many other biochemical tests, serum AST and ALT levels do not follow a normal bell-shaped distribution in the population.9 Instead, AST and ALT values have a skewed distribution characterized by a long "tail" at the high end of the scale (Figure 1).5 For example, the mean values for ALT are very similar from one population to another, but the degree to which the distribution is skewed varies by gender and ethnicity. The ALT distributions in males and nonwhites (i.e., blacks and Hispanics) tend to have a larger tail at the high end, so that more values fall above the upper limits of normal set for the average population.10,11

AST and ALT values are higher in obese patients, probably because these persons commonly have fatty livers.12 ALT levels have been noted to decline with weight loss.13 Depending on the physician's point of view, the upper limits of normal for AST and ALT levels could be set higher for more obese persons.

Rare individuals have chronically elevated AST levels because of a defect in clearance of the enzyme from the circulation.14 For both AST and ALT, the average values and upper limits of normal in patients undergoing renal dialysis are about one half of those found in the general population.15 Mild elevations of ALT or AST in asymptomatic patients can be evaluated efficiently by considering alcohol abuse, hepatitis B, hepatitis C and several other possible diagnoses (Table 2).5

Various liver diseases are associated with typical ranges of AST and ALT levels (Figure 2). ALT levels often rise to several thousand units per liter in patients with acute viral hepatitis. The highest ALT levels--often more than 10,000 U per L--are usually found in patients with acute toxic injury subsequent to, for example, acetaminophen overdose or acute ischemic insult to the liver. AST and ALT levels usually fall rapidly after an acute insult.

Lactate dehydrogenase (LDH) is less specific than AST and ALT as a marker of hepatocyte injury. However, it is worth noting that LDH is disproportionately elevated after an ischemic liver injury.16

It is especially important to remember that in patients with acute alcoholic hepatitis, the serum AST level is almost never greater than 500 U per L and the serum ALT value is almost never greater than 300 U per L. The reasons for these limits on AST and ALT elevations are not well understood. In typical viral or toxic liver injury, the serum ALT level rises more than the AST value, reflecting the relative amounts of these enzymes in hepatocytes. However, in alcoholic hepatitis, the ratio of AST to ALT is greater than 1 in 90 percent of patients and is usually greater than 2.17 The higher the AST-to-ALT ratio, the greater the likelihood that alcohol is contributing to the abnormal LFTs. In the absence of alcohol intake, an increased AST-to-ALT ratio is often found in patients with cirrhosis.

The elevated AST-to-ALT ratio in alcoholic liver disease results in part from the depletion of vitamin B6 (pyridoxine) in chronic alcoholics.18 ALT and AST both use pyridoxine as a coenzyme, but the synthesis of ALT is more strongly inhibited by pyridoxine deficiency than is the synthesis of AST. Alcohol also causes mitochondrial injury, which releases the mitochondrial isoenzyme of AST.

Patients with alcoholic hepatitis can present with jaundice, abdominal pain, fever and a minimally elevated AST value, thereby leading to a misdiagnosis of cholecystitis. This is a potentially fatal mistake given the high surgical mortality rate in patients with alcoholic hepatitis.19
{short description of image}
Typical AST or ALT Values in Disease
Figure 2

FIGURE 2. Typical serum aspartate aminotransferase (AST) or alanine aminotransferase (ALT) values for various diseases. Note that the horizontal axis is a log scale. As shown, the aminotransferases are often normal in patients with cirrhosis. In patients with uncomplicated alcoholic hepatitis, the AST value is rarely greater than 500 U per L and is usually no more than 200 to 300 U per L. The highest peak aminotransferase values are found in patients with acute ischemic or toxic liver injury.

Markers of Cholestasis

Cholestasis (lack of bile flow) results from the blockage of bile ducts or from a disease that impairs bile formation in the liver itself. AP and gamma-glutamyltransferase (GGT) levels typically rise to several times the normal level after several days of bile duct obstruction or intrahepatic cholestasis. The highest liver AP elevations--often greater than 1,000 U per L, or more than six times the normal value--are found in diffuse infiltrative diseases of the liver such as infiltrating tumors and fungal infections.

Patients with cirrhosis often have normal or only slightly elevated serum aspartate aminotransferase or alanine aminotransferase values.
{short description of image}

Diagnostic confusion can occur when a patient presents within a few hours after acute bile duct obstruction from a gallstone. In this situation, AST and ALT levels often reach 500 U per L or more in the first hours and then decline, whereas AP and GGT levels can take several days to rise.

Both AP and GGT levels are elevated in about 90 percent of patients with cholestasis.20 The elevation of GGT alone, with no other LFT abnormalities, often results from enzyme induction by alcohol or aromatic medications in the absence of liver disease. The GGT level is often elevated in persons who take three or more alcoholic drinks (45 g of ethanol or more) per day.21 Thus, GGT is a useful marker for immoderate alcohol intake. Phenobarbital, phenytoin (Dilantin) and other aromatic drugs typically cause GGT elevations of about twice normal. A mildly elevated GGT level is a typical finding in patients taking anticonvulsants and by itself does not necessarily indicate liver disease.22,23

Serum AP originates mostly from liver and bone, which produce slightly different forms of the enzyme. The serum AP level rises during the third trimester of pregnancy because of a form of the enzyme produced in the placenta. When serum AP originates from bone, clues to bone disease are often present, such as recent fracture, bone pain or Paget's disease of the bone (often found in the elderly). Like the GGT value, the AP level can become mildly elevated in patients who are taking phenytoin.22,23

If the origin of an elevated serum AP level is in doubt, the isoenzymes of AP can be separated by electrophoresis. However, this process is expensive and usually unnecessary because an elevated liver AP value is usually accompanied by an elevated GGT level, an elevated 5?-nucleotidase level and other LFT abnormalities.

In one study,24 isolated AP elevations were evaluated in an unselected group of patients at a Veterans Affairs hospital. Most mild AP elevations (less than 1.5 times normal) resolved within six months, and almost all greater elevations had an evident cause that was found on routine clinical evaluation.

Persistently elevated liver AP values in asymptomatic patients, especially women, can be caused by primary biliary cirrhosis, which is a chronic inflammatory disorder of the small bile ducts. Serum antimitochondrial antibody is positive in almost all of these patients.

Indicators of How Well the Liver Functions

Bilirubin
Bilirubin results from the enzymatic breakdown of heme. Unconjugated bilirubin is conjugated with glucuronic acid in hepatocytes to increase its water solubility and is then rapidly transported into bile. The serum conjugated bilirubin level does not become elevated until the liver has lost at least one half of its excretory capacity. Thus, a patient could have obstruction of either the left or right hepatic duct without a rise in the bilirubin level.

Because the secretion of conjugated bilirubin into bile is very rapid in comparison with the conjugation step, healthy persons have almost no detectable conjugated bilirubin in their blood. Liver disease mainly impairs the secretion of conjugated bilirubin into bile. As a result, conjugated bilirubin is rapidly filtered into the urine, where it can be detected by a dipstick test. The finding of bilirubin in urine is a particularly sensitive indicator of the presence of an increased serum conjugated bilirubin level.
{short description of image}
The gamma-glutamyltransferase level is often elevated in persons who have three or more alcoholic drinks per day; thus, it is a useful marker for immoderate alcohol intake.
{short description of image}

In many healthy persons, the serum unconjugated bilirubin is mildly elevated to a concentration of 2 to 3 mg per dL (34 to 51 ?mol per L) or slightly higher, especially after a 24-hour fast. If this is the only LFT abnormality and the conjugated bilirubin level and complete blood count are normal, the diagnosis is usually assumed to be Gilbert syndrome, and no further evaluation is required. Gilbert syndrome was recently shown to be related to a variety of partial defects in uridine diphosphate-glucuronosyl transferase, the enzyme that conjugates bilirubin.25

[Bill.P.]

Blood work and liver functioning

cont....
Mild hemolysis, such as that caused by hereditary spherocytosis and other disorders, can also result in elevated unconjugated bilirubin values, but hemolysis is not usually present if the hematocrit and blood smear are normal. The presence of hemolysis can be confirmed by testing other markers, such as haptoglobin, or by measuring the reticulocyte count.

Severe defects in bilirubin transport and conjugation can lead to markedly elevated unconjugated bilirubin levels, which can cause serious neurologic damage (kernicterus) in infants. However, no serious form of liver disease in adults causes elevation of unconjugated bilirubin levels in the blood without also causing elevation of conjugated bilirubin values.

When a patient has prolonged, severe biliary obstruction followed by the restoration of bile flow, the serum bilirubin level often declines rapidly for several days and then slowly returns to normal over a period of weeks. The slow phase of bilirubin clearance results from the presence of delta-bilirubin, a form of bilirubin chemically attached to serum albumin.26 Because albumin has a half-life of three weeks, delta-bilirubin clears much more slowly than bilirubin-glucuronide. Clinical laboratories can measure delta-bilirubin concentrations, but such measurements are usually unnecessary if the physician is aware of the delta-bilirubin phenomenon.

Albumin
Although the serum albumin level can serve as an index of liver synthetic capacity, several factors make albumin concentrations difficult to interpret.27 The liver can synthesize albumin at twice the healthy basal rate and thus partially compensate for decreased synthetic capacity or increased albumin losses. Albumin has a plasma half-life of three weeks; therefore, serum albumin concentrations change slowly in response to alterations in synthesis. Furthermore, because two thirds of the amount of body albumin is located in the extravascular, extracellular space, changes in distribution can alter the serum concentration.

In practice, patients with low serum albumin concentrations and no other LFT abnormalities are likely to have a nonhepatic cause for low albumin, such as proteinuria or an acute or chronic inflammatory state. Albumin synthesis is immediately and severely depressed in inflammatory states such as burns, trauma and sepsis, and it is commonly depressed in patients with active rheumatic disorders or severe end-stage malnutrition. In addition, normal albumin values are lower in pregnancy.
{short description of image}
Patients with low serum albumin levels and no other liver function test abnormalities are likely to have a nonhepatic cause for low albumin, such as proteinuria.
{short description of image}

Prothrombin Time
The liver synthesizes blood clotting factors II, V, VII, IX and X. The prothrombin time (PT) does not become abnormal until more than 80 percent of liver synthetic capacity is lost. This makes PT a relatively insensitive marker of liver dysfunction. However, abnormal PT prolongation may be a sign of serious liver dysfunction. Because factor VII has a short half-life of only about six hours, it is sensitive to rapid changes in liver synthetic function. Thus, PT is very useful for following liver function in patients with acute liver failure.

An elevated PT can result from a vitamin K deficiency. This deficiency usually occurs in patients with chronic cholestasis or fat malabsorption from disease of the pancreas or small bowel. A trial of vitamin K injections (e.g., 5 mg per day administered subcutaneously for three days) is the most practical way to exclude vitamin K deficiency in such patients. The PT should improve within a few days.

Blood Ammonia
Measurement of the blood ammonia concentration is not always useful in patients with known or suspected hepatic encephalopathy. Ammonia contributes to hepatic encephalopathy; however, ammonia concentrations are much higher in the brain than in the blood and therefore do not correlate well.28 Furthermore, ammonia is not the only waste product responsible for encephalopathy. Thus, blood ammonia concentrations show only a mediocre correlation with the level of mental status in patients with liver disease. It is not unusual for the blood ammonia concentration to be normal in a patient who is in a coma from hepatic encephalopathy.

Blood ammonia levels are best measured in arterial blood because venous concentrations can be elevated as a result of muscle metabolism of amino acids. Blood ammonia concentrations are most useful in evaluating patients with stupor or coma of unknown origin. It is not necessary to evaluate blood ammonia levels routinely in patients with known chronic liver disease who are responding to therapy as expected.

Grading Liver Function Using the Child-Turcotte Class as Modified by Pugh*
Points
Feature 0 1 2
Albumin More than 3.5 g per dL (35 g per L) 2.8 to 3.5 g per dL (28 to 35 g per L) Less than 2.8 g per dL (28 g per L)
Bilirubin Less than 2 mg per dL (34 ?mol per L) 2 to 3 mg per dL (34 to 51 ?mol per L) More than 3 mg per dL
Prolongation of prothrombin time Less than 4 seconds 4 to 6 seconds More than 6 seconds
Ascites None Controlled Refractory
Encephalopathy None Controlled Refractory

*--The Child-Turcotte class, as modified by Pugh, often known simply as the "Child class," is calculated by adding the points as determined by the patient's laboratory results: class A=0 to 1; class B=2 to 4; class C=5 and higher. The classes indicate severity of liver dysfunction: class A is associated with a good prognosis, and class C is associated with limited life expectancy. Ascites and encephalopathy are graded as "none," "controlled with routine medical therapy" or "refractory to medical therapy."

Grading Liver Function by Child-Turcotte Class

In communicating among themselves, many physicians use the Child-Turcotte class as modified by Pugh, often termed the "Child class," to convey information about overall liver function and prognosis (Table 3).29 This grading system can be used to predict overall life expectancy and surgical mortality in patients with cirrhosis and other liver diseases.30

For elective general abdominal surgery, perioperative mortality is in the neighborhood of several percent for patients who fall into the Child class A, 10 to 20 percent for those in class B and approximately 50 percent for those in class C.31 These percentages must be balanced by prognostic considerations when transplantation becomes an option. The presence of cirrhosis by itself is not an indication for liver transplantation, and transplantation is rarely performed in patients who fall into Child class A. For example, the 10-year survival rate is as high as 80 percent in patients with hepatitis C and cirrhosis who have Child class A liver function and no variceal bleeding.32 However, once patients with any type of liver disease fall into the Child-Turcotte class B or class C category, survival is significantly reduced and transplantation should be considered.

So Bill, from what I gather, if you have normal range LFTs, you will most likely be in Child Class A.

However, being in Child Class A does not mean that your liver isnt damaged, it just means that it is functioning despite the damage.

Is that correct?

Thanks

Thanks for the paste. Great to understand the different tests, abnormal results and their interpretations. Something I want to re-read once a month or so.

Blood work and liver functioning

Wow, Bill, what an incredibly thorough reply!!!! Thank you so much.

I am still waiting on my blood test results. My dr took the tests to get a baseline for putting me on Abilify, which I took one day and will not take again. (Would rather have mild depression than the side effects I experienced on one day of that drug!!) My dr will most likely be disappointed in that my side effects once again trump another med. (I think she is getting fed up with my "side effects" to all the drugs she prescribes!)

I will be seeing her next week so I will get the results. I understand the liver functioning test is quite variable. In any case, sounds like milk thistle and lecithen are my friends!

"Conversely, patients who present soon after passing common bile duct stones can be misdiagnosed with acute hepatitis because aminotransferase levels often rise immediately, but alkaline phosphatase and gamma-glutamyltransferase levels do not become elevated for several days."

I recall when in the ER being diagnosed with what ended up as a blocked bile duct, being asked if I was an alcoholic or did I have hepititis. Neither of which I had.
