Hepatitis, acute Health Dictionary

Hepatitis, Acute: From 1 Different Sources


Short-term inflammation of the liver, which usually recovers in 1–2 months. In some cases, acute hepatitis may progress to chronic hepatitis (see hepatitis, chronic), but it rarely leads to acute liver failure.

Acute hepatitis is fairly common.

The most frequent cause is infection with one of the hepatitis viruses (see hepatitis, viral), but it can arise as a result of other infections such as cytomegalovirus infection or Legionnaires’ disease.

It may also occur as a result of overdose of halothane or paracetamol or exposure to toxic chemicals including alcohol (see liver disease, alcoholic).

Symptoms range from few and mild to severe with pain, fever, and jaundice.

Blood tests, including liver function tests, may be used for diagnosis.

In most cases of acute viral hepatitis, natural recovery occurs within a few weeks.

If the disorder is caused by exposure to a chemical or drug, detoxification using an antidote may be possible.

Intensive care may be required if the liver is badly damaged.

Rarely, a liver transplant is the only way of saving life.

In all cases, alcohol should be avoided.

Acute Respiratory Distress Syndrome (ards)

Formerly known as adult respiratory distress syndrome. A form of acute respiratory failure in which a variety of di?erent disorders give rise to lung injury by what is thought to be a common pathway. The condition has a high mortality rate (about 70 per cent); it is a complex clinical problem in which a disproportionate immunological response plays a major role. (See IMMUNITY.)

The exact trigger is unknown, but it is thought that, whatever the stimulus, chemical mediators produced by cells of the immune system or elsewhere in the body spread and sustain an in?ammatory reaction. Cascade mechanisms with multiple interactions are provoked. CYTOTOXIC substances (which damage or kill cells) such as oxygen-free radicals and PROTEASE damage the alveolar capillary membranes (see ALVEOLUS). Once this happens, protein-rich ?uid leaks into the alveoli and interstitial spaces. SURFACTANT is also lost. This impairs the exchange of oxygen and carbon dioxide in the lungs and gives rise to the clinical and pathological picture of acute respiratory failure.

The typical patient with ARDS has rapidly worsening hypoxaemia (lack of oxygen in the blood), often requiring mechanical ventilation. There are all the signs of respiratory failure (see TACHYPNOEA; TACHYCARDIA; CYANOSIS), although the chest may be clear apart from a few crackles. Radiographs show bilateral, patchy, peripheral shadowing. Blood gases will show a low PaO2 (concentration of oxygen in arterial blood) and usually a high PaCO2 (concentration of carbon dioxide in arterial blood). The lungs are ‘sti?’ – they are less e?ective because of the loss of surfactant and the PULMONARY OEDEMA.

Causes The causes of ARDS may be broadly divided into the following:... acute respiratory distress syndrome (ards)

Halothane Hepatitis

A very rare form of HEPATITIS following exposure to HALOTHANE during anaesthesia (1:35,000 halothane anaesthetics). Jaundice develops three to four days after exposure and will occasionally develop into a fatal massive hepatic necrosis. It is of unknown aetiology but probably has an immunological basis. It is more common following multiple exposures in a short time (less than 28 days), and in obesity, middle age and females. It is rare in children.... halothane hepatitis

Hepatitis Viruses

The most common causes of viral hepatitis are those caused by the Hepatitis A, B, C, D, E and G viruses. Hepatitis F virus has been described but is a doubtful entity. Other viruses which can cause hepatitis include the Epstein-Barr Virus, cytomegalovirus, and the Yellow Fever virus.... hepatitis viruses

Liver – Hepatitis C

Paul Bergner describes 4 cases of patients with chronic hepatitis C successfully treated. All were given Milk Thistle, and prescribed an alternative tea: equal parts, Burdock, Dandelion, Barberry, Liquorice, Cinnamon and Fennel. Chologogue action is important in chronic liver disease. Not used in acute inflammation. All patients felt better within 2 weeks, and had liver function tests at 3-monthly intervals, showing a gradual decline in elevated values until normal or almost so. All patients became symptom-free. (Medical Herbalism, Vol 6, No 4) ... liver – hepatitis c

Bright’s Disease (acute)

Glomerulonephritis. Recognised by slight puffiness of the eyes and a dropsical accumulation of fluid in body cavities. Blood pressure rises. Appetite disappears. Digestion is deranged, urine may be blood-stained and a variety of symptoms present as dizziness, headache, nausea. Commonly caused by post streptococcal throat infection circulating in the blood, yet it is now known that the condition may arise from exposure to common garden insecticides and toxic substances of commercial importance that alter the body’s immune system and affect kidney function.

Acute toxic nephritis is possible in the convalescent stage of scarlet and other infectious fevers, even influenza. Causes are legion, including septic conditions in the ear, nose, throat, tonsils, teeth or elsewhere. Resistance to other infections will be low because of accumulation of toxins awaiting elimination. When protein escapes from the body through faulty kidneys general health suffers.

This condition should be treated by or in liaison with a qualified medical practitioner.

Treatment. Bedrest essential, with electric blanket or hot water bottle. Attention to bowels; a timely laxative also assists elimination of excessive fluid. Diuretics. Diaphoretics. Abundant drinks of bottled water or herb teas (3-5 pints daily). Alkaline drinks have a healing effect upon the kidneys. Juniper is never given for active inflammation.

Useful teas. Buchu, Cornsilk, Couchgrass, Clivers, Bearberry, Elderflowers, Marshmallow, Mullein, Marigold flowers, Wild Carrot, Yarrow.

Gingivitis, Acute Ulcerative

Painful infection and ulceration of the gums due to abnormal growth of bacteria that usually exist harmlessly in small numbers in gum crevices. Predisposing factors include poor oral hygiene, smoking, throat infections, and emotional stress. In many cases the disorder is preceded by gingivitis or periodontitis. The condition is uncommon, primarily affecting people aged 15–35.

The gums become sore and bleed at the slightest pressure. Crater-like ulcers develop on the gum tips between teeth, and there may be a foul taste in the mouth, bad breath, and swollen lymph nodes. Sometimes, the infection spreads to the lips and cheek lining (see noma).

A hydrogen peroxide mouthwash can relieve the inflammation.

Scaling is then performed to remove plaque.

In severe cases, the antibacterial drug metronidazole may be given to control infection.... gingivitis, acute ulcerative

Hepatitis A

Also known as epidemic hepatitis, this disorder is caused by the hepatitis A virus, which is transmitted to people in contaminated food or drink.

The incubation period lasts for 15–40 days, after which nausea, fever and jaundice develop.

Recovery usually occurs within 3 weeks.

Serious complications are rare.

Active immunization provides the best protection against hepatitis A, and an attack can confer immunity.... hepatitis a

Hepatitis C

Caused by the hepatitis C virus and formerly known as non-A non-B hepatitis, this infection is often transmitted through sharing needles. Blood transfusions no longer pose a significant risk because of blood screening.

Hepatitis C has an incubation period of 6–12 months and begins as a mild illness which may go undetected. In about 3 in 4 patients, chronic hepatitis develops (see hepatitis, chronic), which can progress to cirrhosis of the liver and an increased risk of hepatoma.... hepatitis c

Hepatitis D

An infection of the liver caused by the hepatitis D virus, which occurs only in people who already have hepatitis B infection. People who develop hepatitis D will usually suffer from severe chronic liver disease.... hepatitis d

Hepatitis E

A type of hepatitis, caused by the hepatitis E virus, transmitted in contaminated food or drink. The disease is similar to hepatitis A.... hepatitis e

Hepatitis B

Formerly known as serum hepatitis, this disorder is due to the hepatitis B virus, which is transmitted in infected blood, blood products, or other body fluids, often through contact with needles, blood transfusions, or sexual contact. After an incubation period of 1–6 months, the onset of symptoms, such as headache, fever, and jaundice, is sudden. Most patients recover, but hepatitis B can be fatal. A vaccine is available.

In about 5 percent of cases, the virus continues to cause inflammation and can still be detected in the blood 6 months after infection. People who suffer from persistent infection are at long-term risk of liver cancer and cirrhosis and may be treated with interferon.... hepatitis b

Hepatitis, Chronic

Inflammation of the liver persisting for a prolonged period. Eventually, scar tissue forms and liver cirrhosis may develop.Chronic hepatitis may develop following an attack of acute hepatitis (see hepatitis, acute). It may also occur as the result of an autoimmune disorder, a viral infection (see hepatitis, viral), a reaction to certain types of drugs or, more rarely, to a metabolic disorder, such as haemochromatosis or Wilson’s disease.

Chronic hepatitis may cause slight tiredness or no symptoms at all.

It is diagnosed by liver biopsy.

Autoimmune hepatitis is treated with corticosteroid drugs and immunosuppressants.

Viral infections often respond to interferon.

In the drug-induced type, withdrawal of the medication can lead to recovery.

For metabolic disturbances, treatment depends on the underlying disorder.... hepatitis, chronic

Hepatitis, Viral

Any type of hepatitis caused by a viral infection.

Five viruses that attack the liver as their primary target have been identified.

They cause hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E.... hepatitis, viral

Leukaemia, Acute

A type of leukaemia in which excessive numbers of immature white blood cells called blasts are produced in the bone marrow. If untreated, acute leukaemia can be fatal within a few weeks or months. The abnormal cells may be of 2 types: lymphoblasts (immature lymphocytes) in acute lymphoblastic leukaemia, and myeloblasts (immature forms of other types of white cell) in acute myeloblastic leukaemia.

Exposure to certain chemicals (such as benzene and some anticancer drugs) or high levels of radiation may be a cause in some cases. Inherited factors may also play a part; there is increased incidence in people with certain genetic disorders (such as Fanconi’s anaemia) and chromosomal abnormalities (such as Down’s syndrome). People with blood disorders such as chronic myeloid leukaemia (see leukaemia, chronic myeloid) and primary polycythaemia are at increased risk, as their bone marrow is already abnormal.

The symptoms and signs of acute leukaemia include bleeding gums, easy bruising, headache, bone pain, enlarged lymph nodes, and symptoms of anaemia, such as tiredness, pallor, and breathlessness on exertion. There may also be repeated chest or throat infections. The diagnosis is based on a bone marrow biopsy. Treatment includes transfusions of blood and platelets, the use of anticancer drugs, and possibly radiotherapy. A bone marrow transplant may also be required. The outlook depends on the type of leukaemia and the age of the patient. Chemotherapy has increased success rates and 6 in 10 children with the disease can now be cured, although treatment is less likely to be completely successful in adults.... leukaemia, acute

Urethral Syndrome, Acute

A set of symptoms, usually affecting women, that are very similar to cystitis but which occur in the absence of infection.... urethral syndrome, acute

Acute Abdomen

the sudden uncontrolled development of severe abdominal symptoms secondary to disease or injury. Failure to establish a prompt diagnosis may lead to rapid clinical decline. Perforation of a peptic ulcer, an inflamed appendix or colonic diverticulum, or rupture of the liver or spleen following a crush injury all produce an acute abdomen requiring urgent treatment.... acute abdomen

Acute Coronary Syndrome

a combination of angina (unstable or stable), non-S–T elevation *myocardial infarction (NSTEMI), and S–T elevation myocardial infarction (STEMI). It implies the presence of coronary artery disease.... acute coronary syndrome

Acute Fatty Liver Of Pregnancy

a rare and life-threatening complication of pregnancy that usually presents in the third trimester with symptoms of nausea, vomiting, malaise, and abdominal pain. Liver function tests are abnormal and the features of *pre-eclampsia and often *HELLP syndrome are present. *Hepatic encephalopathy, *disseminated intravascular coagulation, and renal failure may develop, and the condition is associated with a high maternal and fetal mortality. Treatment involves a multidisciplinary approach, usually in an intensive care unit.... acute fatty liver of pregnancy

Acute Generalized Exanthematous Pustulosis

(toxic pustuloderma) a reaction to a medication, resulting in the appearance of fine sterile *pustules on inflamed skin; the pustules may easily be overlooked.

Acute Rheumatism

see rheumatic fever.... acute rheumatism

Acute Tubular Necrosis

(ATN) a condition caused by acute renal injury from either ischaemia or toxins and associated with tubular damage that is usually reversible. The earliest feature is *isosthenuria, which may occur while there is still a high urine flow rate. This is followed by a reduction in *glomerular filtration rate. *Oliguria is common and dialysis often needed for survival. If the cause of the initial damage can be removed, recovery of renal function within six weeks can be expected in most cases.... acute tubular necrosis

Myoglobinuric Acute Renal Failure

acute kidney injury caused by myoglobin that is released from damaged skeletal muscle (*rhabdomyolysis). This is usually the result of trauma and the condition was first recognized in victims trapped and crushed during the London Blitz. Muscle injury can also occur with pressure necrosis, particularly in the unconscious or immobile patient, or with a *compartment syndrome. Rarely it may complicate intensive muscular exercise or extensive viral myositis and it is a recognized complication of modest overexertion in some inherited disorders of muscle metabolism, such as *McArdle’s disease.... myoglobinuric acute renal failure
