What is toxic hepatitis?

Toxic liver damage, or toxic hepatitis, is a condition that occurs as a result of exposure to medications or various types of toxins.

Medications, food additives, chemicals, solvents, and alcohol are the most common causes of toxic liver damage.

Environmental toxins – heavy metals, industrial chemicals, pesticides, and other air pollutants cause liver damage through various mechanisms, such as oxidative stress, inflammation, and direct cytotoxic effects.

The effects of exposure to these toxins are manifested by a variety of symptoms, or sometimes completely asymptomatic, with abnormalities in liver function tests.

Types of toxic hepatitis

Acute toxic hepatitis: This type of disease develops suddenly. Symptoms begin to appear within a short period of time after exposure to the toxin.
Chronic toxic hepatitis: This type of disease progresses over a long period of time, sometimes completely asymptomatic, and is detected during a random examination – by abnormal liver function test results.

Hepatitis caused by chemicals: It is the result of direct contact with various poisons, inhalation, or ingestion.
Drug-induced hepatitis: It is the result of taking a specific group of hepatotoxic medications (acetaminophen, nonsteroidal anti-inflammatory drugs, etc.).
Alcoholic hepatitis: It develops as a result of alcohol and sometimes drug use.

What happens during chronic intoxication?

The liver filters all kinds of substances that enter the body. Toxic metabolites formed during the processing of substances also have a damaging effect on the body and the liver.

Toxic liver damage can be moderate or severe. Long-term toxic exposure can lead to connective tissue degeneration of the liver tissue and cirrhosis.

Symptoms of toxic liver damage

Fever
Diarrhea
Dark urine
Itchy skin
Red, maculopapular rash on the skin
Jaundice – yellowing of the skin and mucous membranes
headache
Ingratitude
Nausea/vomiting
stomach-ache
weight loss
Whitish stool

Hepatotoxic medications

A number of medications can cause liver damage:

Painkillers:

Acetaminophen
Nonsteroidal anti-inflammatory drugs (aspirin, ibuprofen, naproxen)

Prescription medications:

Statins
Antibiotics
Azathioprine and methotrexate group medications (rheumatological)
Antifungal medications
Niacin
Steroids
Allopurinol and anti-gout medications
Antiviral drugs
Chemotherapy drugs

Hepatotoxic chemicals and solvents

Vinyl chlorides – used in the production of plastics
Carbon tetrachloride – a dry cleaning agent
Paraquat – a weed killer
Polychlorinated biphenyls and others.

Risk factors for toxic liver damage

Taking higher than recommended doses of painkillers and nonsteroidal anti-inflammatory drugs
Presence of any liver disease or metabolic disorders
Alcohol consumption during therapy with certain medications
Occupational intoxication with industrial chemicals and toxins
Age
Female gender
Genetic predisposition

Diagnosis of toxic liver damage

If one or more of the above symptoms are detected, it is necessary to visit a specialist and assess the functional state of the liver.

Along with anamnestic and clinical data, laboratory and, if necessary, instrumental diagnostics are important.

From blood tests, it is necessary to perform liver function tests:

Alanine aminotransferase (ALT) A liver enzyme that is involved in the liver's protein metabolism and energy production. Elevated levels indicate liver damage.

Aspartate aminotransferase (AST) It is an enzyme involved in the breakdown of amino acids.

Alkaline phosphatase (APT) It is an enzyme involved in protein metabolism, which is involved in energy production for liver cells.

Bilirubin It is a product of hemoglobin degradation and is part of bile. Its increase in quantity occurs for various reasons, but it can often indicate liver damage.

Gammaglutamyltransferase (GGT) It is a cellular enzyme found in almost all cells, but mainly in liver cells. It performs a protective function for the cell. An increase in its concentration in the blood is a marker of liver cell damage.

Lactate dehydrogenase (LDH) It is an enzyme involved in cellular energy metabolism. Its concentration is increased not only in liver diseases, but also in pathologies of the skeletal system.

Prothrombin time (PT) It is time for a blood clot to form. It is characterized by liver damage. PT High rate (prolonged clotting time), which can also be caused by some blood thinners.

Instrumental imaging studies allow us to study the structure of the liver in detail.

Treatment of toxic hepatitis

In the process of treating toxic hepatitis, it is important to stop or limit the intake of toxic substances and medications.

Medication substitution
Avoid taking chemical and herbal supplements
Alcohol prevention

Symptoms begin to decrease within a few days of eliminating these causes.

If necessary, the patient should be hospitalized and symptomatic treatment should be provided.

Prevention

Only take necessary medications, in the dosage recommended by your doctor.
Avoid taking biological and nutritional supplements
Stopping or limiting alcohol consumption
Taking maximum precautions when working with toxins and solvents
Maintaining a healthy diet and lifestyle

There is evidence that 2 cups of coffee a day can prevent liver fibrosis.

Does toxic hepatitis heal on its own?

Whether toxic hepatitis can be cured with Tavis depends on the causes of intoxication, the severity and duration of the process, the degree of liver damage, etc. In cases of moderate damage, when the toxic effects are temporary, the functional state of the liver may improve spontaneously.

Is toxic hepatitis curable?

Hepatitis may be treatable, depending on the severity of the intoxication and organ damage. If the cause of the damage is alcohol or nonsteroidal anti-inflammatory drugs, which the patient can quickly stop taking, recovery may occur within a few weeks or months.
