Cirrhosis
|
A liver biopsy is the only definitive test that actually indicates whether or not you have cirrhosis [irreversible scaring of the liver]. So, what exactly is your doctor looking for when he/she does a physical exam? Are there actually some physical clues that suggest that you have cirrhosis? The answer to this question is yes. The following is a list of clues that indicate that you may already have cirrhosis. These are listed alphabetically by their common medical name. It is important to remember that, although helpful, each of these physical manifestations do not indicate the actual cause of one's liver disease, and, in fact, are not specific only to liver disease. They can be due to other disorders as well.
ASCITES An accumulation of excess fluid in the abdomen. Causes abdominal distention. Can be treated with a low sodium diet, and the use of diuretics, i.e. water pills. Ascites: In about 5% of cirrhotic patients a pleural effusion may be found, usually to the right side. It is due to defects in the diaphragm allowing ascites to pass into the pleural cavity. Right pleural effusion may be seen in the absence of ascites due to the negative intrathoracic pressure during breathing, drawing the peritoneal fluid through the diaphragmatic defects into the pleural cavity. PHOTO: ASTERIXIS An uncontrollable flapping of the hands that becomes noticeable when patients stretch out their arms, palms out, as if stopping traffic. Is associated with mental confusion, i.e. encephalopathy. To Test For Asterixis: http://www.tcd.ie/tsmj/2000/Asterxs.html Extend the arms, spread the fingers, dorsiflex the wrist and observe for the abnormal “flapping” tremor at the wrist. If not immediately apparent, this tremor may be accentuated by asking the patient to keep the arms straight while the examiner gently hyperextends the patient’s wrist with a sweeping motion. An alternate method of testing for asterixis involves having the patient relax his legs while he lies supine with his knees bent. The feet should be kept flat on the table and as the legs fall to the sides, watch for flapping of the legs at the hip joint. This repetitively brings the knees back together. "Bilateral Asterixis": Other causes of asterixis include
cardiac and respiratory disease, electrolyte abnormalities
and drug intoxication. 2000 Trinity Student Medical Journal (Photo of how to test for Asterixis: )

appearance of distended and engorged umbilical veins which
are seen radiating from the umbilicus across the abdomen
to join systemic veins. It is a sign of severe portal
hypertension with portal-systemic shunting through the
umbilical veins.
Caput Medusae is distinguished from inferior vena cava obstruction by determining the direction of flow in the veins below the umbilicus; it is towards the legs in the former, and towards the head in the latter (as abdominal collaterals develop to bypass the blocked inferior vena cava and permit venous return from the legs).

A significantly greater number of carious and missing teeth were observed in the patients with cirrhosis than in a control group of 50 healthy individuals. In the LC group, caries were found to affect more teeth in those patients with alcohol-induced LC than in those with liver disease of other causes. Finally, no relationship was observed between the number
of carious, missing or filled teeth and certain determinations including
serum glutamate pyruvate transaminase (SGPT), serum glutamate oxalacetate
transaminase (SGOT), alkaline phosphate, platelet number, hepatitis B and
C positivity markers, or antinuclear (ANA), antimitochondrial (AMA) or
anti-smooth muscle autoantibodies (ASm). http://www.ncbi.nlm.nih.gov/entrez/q uery.fcgi?cmd=Retrieve&db=PubMed&list_uids=9203745&dopt=Abstract
DMFT and CPITN indices were recorded at a clinic providing priority dental care for people with hepatitis C infection. The data were compared with information from an existing survey of general dental patients. Social impact was assessed using a modified Oral Health Impact Profile questionnaire. The DMFT index differed significantly between hepatitis C and general patients. The number of decayed and missing teeth was greater in those infected with hepatitis C for all patients aged between 25 and 50 years. Although there was no significant difference in CPITN categories for subjects evaluated, a marked trend for poor periodontal health was noted for those individuals with hepatitis C. Salivary flow was reduced in 50 per cent of hepatitis C infected subjects. Social impact was significantly affected with 71 per cent of hepatitis C subjects reporting painful aching in the mouth and 56 per cent having difficulty in relaxing. In conclusion, the results from the
project strongly indicate an urgent need for priority delivery of dental
care for people with hepatitis C infection.
DUPUYTREN'S CONTRACTURE A puckering of the palms that prevents people from totally straightening out their hand. Usually associated with alcoholic liver disease. EDEMA Fluid accumulation in the legs, especially the ankles. Usually associated with ascites. Edema
Why do patients with liver disease develop ascites and edema? Ascites develops because of a combination of two factors: (1) increased pressure in the vein system that carries blood from the stomach, intestines, and spleen to the liver (portal hypertension); and (2) a low level of albumin in the blood (hypoalbuminemia). Albumin, which is the predominant protein in the blood and which helps maintain blood volume, is reduced in cirrhosis primarily because the damaged liver is not able to produce enough albumin. Other consequences of portal hypertension include dilated veins in the esophagus (varices), prominent veins on the abdomen, and an enlarged spleen. Each of these conditions is due primarily to the increased pressure and accumulation of blood in the abdominal blood vessels. Other signs of chronic liver disease are spider nevi (distinctive vascular malformations) on the skin, certain characteristic changes in the nails, gynecomastia (enlarged breasts), and shrinkage of the testicles (testicular atrophy). The fluid of ascites can be removed from the abdominal cavity by using a syringe and a long needle. This procedure is called paracentesis. Analysis of the fluid can help differentiate ascites that is caused by cirrhosis from other causes of ascites, such as cancer, tuberculosis, congestive heart failure, and nephrosis. Sometimes, when ascites does not respond to treatment with diuretics, paracentesis can be used to remove large amounts of the ascitic fluid. Peripheral edema, which is usually seen as pitting edema of the legs and feet, also occurs in cirrhosis. The edema is a consequence of the hypoalbuminemia and activation of the renin-angiotensin- aldosterone hormonal system, which prompt the kidneys to retain salt and water. The presence or absence of edema in patients with cirrhosis and ascites is an important consideration in the treatment of the ascites. In patients with ascites without edema, diuretics must be given with extra caution. The reason for this is that a diuresis (induced increased volume of urine) that is too depleting or rapid in these patients can lead to a low blood volume (hypovolemia), which can possibly be followed by kidney and liver failure. In contrast, when patients who have both edema and ascites undergo diuresis, the edema fluid in the interstitial space serves as somewhat of a buffer against the development of low blood volume. The excess interstitial fluid moves into the blood vessel spaces to rapidly replenish the depleted blood volume. http://www.focusondiabetes.com/script/main/Art.asp?li=MNI& PHOTOS http://medicine.ucsd.edu/clinicalmed/extremities-massive-edema.jpg http://www.nlm.nih.gov/medlineplus/ency/imagepage/2916.htm ENCEPHALOPATHY An altered mental status leading to coma. Can be treated with animal protein restriction and a poorly absorbed sugar called Lactulose. Encephalopathy is an altered or impaired mental status, typically leading to coma, that can occur in people with cirrhosis. It is often referred to as "brain fog". Encephalopathy is often associated with poor coordination, fetor hepaticus (foul-smelling breath), and asterixis (uncontrollable flapping of the hands). The exact cause of encephalopathy is not known, but is probably due to a combination of factors. Most researchers believe that it mainly has something to do with the ailing liver’s inability to clear toxins—primarily ammonia—from the body. In fact, elevated blood levels of ammonia are found in approximately 90 percent of people with encephalopathy. When ammonia and other poisons begin to accumulate in the brain, a variety of mental disturbances occur. In mild cases – known as minimal hepatic encephalopathy, a person will develop subtle personality changes, such as irritability, a change in sleeping patterns, or short-term memory loss. A person may have a shortened attention span or appear to be apathetic toward life. Movements may appear poorly coordinated and clumsy. People suffering from encephalopathy will commonly lose their tempers over minor incidents or have mood swings for no apparent reason. Or a person may repeatedly enter a room, forgetting what he needed from the room in the first place. Or he may continually misplace common objects, such as reading glasses, only to find that they were on top of his head the whole time! These people may also have an increased incidence of automobile accidents, as their reaction time may be somewhat impaired. In more severe cases, total confusion, associated with inappropriate behavior, will occur. A person may become outright violent or may be so confused that he cannot properly identify the current year, season, or even his own family members. Sometimes, a person will sleep all day and can only be partially aroused. This, obviously, is a more serious condition and requires hospitalization. In most cases, encephalopathy is easily detected on a physical examination in a patient known to have cirrhosis. Whenever there is a question about the diagnosis, an imaging study, such as CT scan or MRI, of the brain should be performed in order to eliminate other potential causes - such as a brain tumor, blood clot, or meningitis (brain infection). The factors that can precipitate encephalopathy in the cirrhotic patient should be searched for and immediately addressed by the doctor. These factors as well as the treatment of encephalopathy will be discussed below.
Grading of hepatic encephalopathy Grade: 1 Grade: 2 Grade: 3 Grade: 4 FETOR HEPATICUS A particularly foul "dead mouse" smell found on the breath. Frequently precedes coma. Portal-Systemic Encephalopathy (PSE) Fetor hepaticus is caused by the mercaptans dimethyl sulfide and methanethiol and may follow the administration of a known precipitant of PSE (Portal-Systemic Encephalopathy), methionine. Fetor hepaticus is a sweetish odor reminiscent of garlic and has been described as "fruity" or "musty". It is commonly but inconsistently detected on the breath or urine of PSE patients, but can be difficult to differentiate from other odors. Therefore, fetor hepaticus has limited usefulness in physical diagnosis. taken from: GYNECOMASTIA Enlarged, tender breasts in men. Commonly associated with alcoholic cirrhosis, but may also be due to Aldactone, a drug used to control ascites. HAIR LOSS Hair becomes sparse in men from the face, chest and pubis, and under the arms in women. JAUNDICE A yellow discoloration of the skin due to an elevated bilirubin level. JAUNDICE The normal level of bilirubin in the blood is 1 mg/dL. If the concentration increases to 2 mg/dL, yellowing of the skin, sclera, and mucous membranes will become evident. Yellowing due to increased levels of bilirubin in the blood (hyperbilirubinemia), which then deposits in the tissues of the body, is called jaundice or icterus. Depending on the site of the problem, hyperbilirubinemia is usually dominated by either the unconjugated or conjugated type. Jaundice can be classified according to the mechanism that produced it:
In young people, jaundice is most frequently due to viral hepatitis or alcohol abuse. In older people, malignancies are a more common cause. Premature infants may develop jaundice due to increased hemolysis and immature liver cells that contain insufficient enzymes to process bilirubin properly. Jaundice itself is not toxic except in newborns. Since their blood-brain barrier is not fully functional, bilirubin can pass into the brain and cause damage. http://www.path.sunysb.edu/courses/hbp310/liver_and_pancreas.htm Low Blood Pressure Many patients with cirrhosis or scarring of the liver develop abnormalities in their cardiovascular system as a result of their liver disease. All diseases that result in cirrhosis can lead to these cardiovascular changes but they occur more frequently in patients with more advanced disease. It is believed that substances circulating in the blood that are normally cleared by a healthy liver can cause a generalized dilatation of the blood vessels throughout the body (except in the kidney where they are intensely constricted) . The generalized vasodilatation then results in a low blood pressure. Most patients with this form of low blood pressure are asymptomatic because of its very gradual onset and because of a compensatory increased blood flow from the heart. There is no specific treatment for the development of low blood pressure in patients with cirrhosis other than general, supportive care. The blood pressure will normalize after removal of the diseased liver and transplantation of a healthy liver.

SPONTANEOUS BACTERIAL PERITONITIS Fever, and abdominal pain in a patient with ascites. Spontaneous Bacterial Peritonitis (SBP) General Information:
A. SBP is a common complication in
patients with cirrhosis and ascites, and occurs mostly in
the setting of low ascitic fluid total protein level (<1
g/dl). Presentation and Diagnosis: A. Abdominal pain and fever are the most characteristic symptoms, but hepatic encephalopathy, gastrointestinal bleeding, vomiting, diarrhea, shock, or hypothermia may be the presenting symptom(s) in a large number of patients. B. It can also be totally asymptomatic. Therefore one must have a low threshold for performing a paracentesis to obtain ascitic fluid for analysis. C. SBP is diagnosed when there is a positive ascitic fluid culture or when the ascitic fluid PMN count is >250 cells/mm3 in the absence of an identifiable intraabdominal source of infection. D. Ascitic fluid culture must be placed directly into blood culture preferably at bedside to increase the sensitivity of culture. E. Secondary peritonitis due to perforated viscus usually results in PMN count in the thousands, multiple organisms on gram stain and culture, and at least 2 of the following: total protein >1 g/dl, LDH > the upper limit of normal for serum, and glucose <50 mg/dl. Treatment: A. Empiric antibiotic treatment should be begun before the culture results become available to prevent demise of the patient. B. A broad-spectrum therapy is recommended in suspected ascitic fluid infection until culture results and susceptibility are available. Cefotamine 2 g IV Q8h or a comparable third-generation cephalosporin is the treatment of choice. Five days of treatment is appropriate. A repeat paracentesis can be performed after completion of 5 days of therapy with IV antibiotics to ensure efficacy of the treatment especially in patients with atypical presentation or response. C. Intravenous albumin at a dose of 1.5 g per kilogram body weight on day 1 and 1 g per kilogram on day 3 has been shown to reduce significantly the incidence of renal impairment and death in comparison with treatment with antibiotics alone. D. Subsequently, these patients should be placed on SBP prophylaxis therapy (norfloxacin 400 mg QD or levofloxacin 250 mg QD) for the remaining part of their hospital stay. http://www.vh.org/Providers/ClinRef/FPHandbook/Chapter05/18-5.html TERRY'S NAILS The normal pinkish color of the nails turns completely white, with the disappearance of the half-moon circles at the base of the nails.

Definition Description Causes & symptoms Platelets come from megakaryocytes, which are produced in the material located within the center cavity of the bones (bone marrow). When abnormalities develop in the marrow, the marrow cells can lose their ability to produce platelets in correct amounts. The result is a lower than normal level of platelets in the blood. Drugs used in cancer chemotherapy can cause the marrow to malfunction in this way, as can the presence of tumor cells in the marrow itself. Normally, the spleen holds about one-third of the body's
platelets as part of this organ's function to recycle aging or damaged red
blood cells (the cells that carry oxygen in the blood). Platelets can breakdown in unusually high amounts in
persons with abnormalities in their blood vessel walls, with blood clots,
or with man-made replacement heart valves. Devices placed inside blood
vessels to keep them from closing (stents) due to weakened walls or fat
build-up can also cause platelets to breakdown. Diagnosis Once a low platelet count is verified, a careful
evaluation of the function of the bone marrow and spleen are necessary.
Improper functioning of either or both of these organs can cause
thrombocytopenia. Treatment Low platelet counts can indicate more serious conditions. If a dysfunctional immune system is found to be the cause for this condition, drugs like steroids or gamma globulin can be used to help maintain platelet levels in certain cases. If low platelet levels are due to an abnormally low level of platelet production, transfusions of platelets can be given as well. Prognosis Prevention Key Terms to know:

UMBILICAL HERNIA Patients with massive ascites may experience abdominal discomfort, depressed appetite, and decreased oral intake. Diaphragmatic elevation may lead to symptoms of dyspnea. Pleural effusions may result from the passage of ascitic fluid across channels in the diaphragm. Umbilical and inguinal hernias are
common in patients with moderate and massive ascites. Umbilical hernias should not undergo elective repair unless patients are significantly symptomatic or their hernias are irreducible. As with all other surgeries in patients with cirrhosis, herniorrhaphy carries multiple potential risks such as intraoperative bleeding, postoperative infection, and liver failure because of anesthesia-induced reductions in hepatic blood flow. However, these risks become acceptable in patients with severe symptoms from their hernia. Urgent surgery is necessary in the patient whose hernia has been complicated by bowel incarceration. http://www.emedicine.com/med/topic3183.htm#section~portal_hypertension Umbilical Hernia PHOTOS: small umbilical hernia large umbilical hernia support belt Picture of cirrhotic liver http://www.ikp.unibe.ch/lab2/cirrhe.html http://www.nlm.nih.gov/medlineplus/ency/imagepages/8849.htm Home page of Melissa Palmer,M.D. copyright © 2000 Melissa Palmer, MD
