DILI medical abbreviation meaning – Drug-Induced Liver Injury

Modern medicine grapples with the significant issue of Drug-Induced Liver Injury (DILI). This condition, linked to adverse medication and supplement effects, can cause varying degrees of liver damage. From mild enzyme elevation to severe liver failure, DILI introduces complications and challenges into clinical scenarios.

The unpredictability of DILI compounds its complexity. Over 1,000 medications and herbal supplements can potentially induce it. This condition accounts for over 50% of acute liver failures in the United States. Therefore, understanding DILI is crucial for its diagnosis, treatment, and prevention.

DILI not only impacts individual patients but also strains global healthcare systems. It leads to increased hospital admissions, extended stays, and higher healthcare costs. Thus, recognizing and managing DILI is a critical aspect of modern medical practice.

Drug-Induced Liver Injury Definition

DILI describes liver damage that drugs or herbal supplements cause. Its severity ranges from mild enzyme elevation to acute liver failure, a leading cause of which is DILI itself. Identifying DILI often hinges on ruling out other liver injury causes. Typically, the diagnosis is confirmed when the suspected agent’s discontinuation leads to improvement.

We usually categorize DILI based on the liver injury pattern observed. It can be hepatocellular, cholestatic, or a mixed pattern. Differentiating these subtypes is crucial for effective patient management.

DILI’s unpredictability lies in its roots. Unlike dose-dependent drug toxicity, DILI often strikes without identifiable risk factors. This trait adds a layer of complexity to the diagnosis and management of DILI.

Medical research has made strides in identifying potential genetic predispositions to DILI. Some human leukocyte antigen (HLA) genotypes increase the risk of developing DILI with specific drugs. These findings hold promise for future DILI prevention.

Drug Induced Liver Injury ICD 10

The International Classification of Diseases, 10th Revision (ICD-10) is a global coding system for diseases. DILI falls under the ICD-10 code K71, which has further subdivisions to specify the liver injury type and severity.

K71.0 denotes toxic liver disease with cholestasis. This DILI subtype signifies impaired bile flow, which results in accumulated bile salts in the liver. Symptoms typically include jaundice and itching.

K71.1 stands for toxic liver disease with hepatic necrosis. This severe liver damage subtype can lead to serious complications like liver failure if not promptly managed.

Codes K71.2 to K71.9 cover other DILI manifestations, including hepatic coma, chronic persistent hepatitis, and unspecified toxic liver disease. These codes ensure accurate documentation, aid research, and enable appropriate healthcare resource allocation.

The ICD-10 coding system provides a standardized language for healthcare providers worldwide. It facilitates smooth communication, enhancing collaborative efforts in patient care and disease prevention.

Drug-Induced Liver Injury Symptoms

DILI symptoms are diverse, reflecting the broad spectrum of potential liver damage. Symptoms may not manifest until significant liver injury has occurred. When they do appear, they are often non-specific, which can complicate diagnosis.

Mild DILI may cause fatigue, weakness, and vague abdominal discomfort. These symptoms can often be mistaken for other conditions, leading to delayed diagnosis. This fact underlines the need for regular liver function monitoring in patients taking hepatotoxic drugs.

More severe liver injury can cause jaundice, dark urine, and pale stools. Accompanying symptoms may include loss of appetite, nausea, and vomiting. These signs suggest impaired liver function and warrant immediate medical attention.

If DILI progresses to acute liver failure, it may cause encephalopathy, characterized by confusion, drowsiness, or coma. This situation is a medical emergency requiring intensive care, possibly even a lifesaving liver transplant.

DILI symptoms can surface weeks to months after drug initiation. This latency period varies, depending on the drug and individual patient factors, further complicating diagnosis.

Drug-Induced Liver Injury Causes

Numerous drugs and herbal supplements can trigger DILI. Common culprits include acetaminophen, statins, amoxicillin-clavulanate, and antiepileptic drugs like valproate and carbamazepine.

Acetaminophen, a common pain reliever and fever reducer, can lead to DILI and acute liver failure when taken excessively. Many unintentional overdoses involve acetaminophen, highlighting the need for public education on safe usage.

Statins, used to manage high cholesterol levels, can cause DILI, though this is rare. The risk increases with higher doses and in patients with pre-existing liver disease. Regular liver function monitoring during statin therapy is advisable.

Amoxicillin-clavulanate, a frequently used antibiotic, is often associated with DILI. Risk increases with age and a history of liver disease. Careful patient selection and regular liver function monitoring can mitigate this risk.

Herbal supplements and alternative medicines are also common culprits, often because patients may not disclose their use. These products aren’t subject to the same rigorous testing as prescription drugs, making their hepatotoxic potential unpredictable and often unrecognized.

Drug-Induced Liver Injury Diagnosis

Diagnosing DILI involves a mix of clinical history, laboratory investigations, and sometimes, liver biopsy. The key is to identify the temporal relationship between the drug and the onset of liver injury, along with excluding other liver disease causes.

A comprehensive medication history is crucial upon suspecting DILI. It should include all prescription drugs, over-the-counter medications, and herbal supplements. The timing of drug initiation and cessation relative to symptom onset can provide vital clues.

Laboratory investigations typically involve liver function tests, including serum transaminases, alkaline phosphatase, and bilirubin levels. These tests can not only support the diagnosis but also help classify the liver injury type and assess severity.

A liver biopsy may be necessary in some cases, especially when the diagnosis is unclear. It can provide valuable information about the extent of liver damage and help rule out other liver disease causes.

Imaging studies, such as ultrasound, CT, or MRI, can also be useful. They help exclude other liver disease causes, such as gallstones or tumors, and provide a visual assessment of liver damage.

The role of genetic testing is emerging in DILI diagnosis. Certain genetic markers have been associated with an increased risk of DILI with specific drugs. While not routinely done, genetic testing may be beneficial in certain high-risk populations.

Drug-Induced Liver Injury Recovery Time

The recovery time from DILI varies greatly, depending on the liver injury’s severity and the patient’s overall health. Recovery may take weeks to months, and in some cases, may be incomplete, leading to chronic liver disease.

In milder cases, where liver injury is detected early and the offending drug is promptly discontinued, recovery may be swift. Liver function typically returns to normal within weeks to a few months. Regular monitoring of liver function tests ensures recovery is on track.

If liver injury is severe, recovery may be prolonged. In some cases, liver function may not fully return to normal, resulting in chronic liver disease. These patients require close follow-up and management of potential complications, such as cirrhosis and liver failure.

In instances where DILI leads to acute liver failure, urgent medical intervention is required. This may involve intensive care support and even liver transplantation. Recovery in these cases is protracted and depends on various factors, including the patient’s overall health, the success of the transplant, and the presence of other complications.

Remember, avoiding re-exposure to the causative drug is vital, as it can lead to recurrent liver injury, often more severe than the initial episode. Educating patients about this is a crucial part of their care.

Treatment of Drug-Induced Liver Injury

In DILI treatment, the immediate discontinuation of the offending drug is key. This action often leads to improvement in liver function and symptom resolution. However, if the drug cannot be stopped or liver injury is severe, other treatments may be necessary.

Supportive care, including hydration and symptom management, is often required. In cases of acetaminophen overdose, administering the antidote, N-acetylcysteine, can limit liver damage.

In severe cases, hospitalization may be necessary for close monitoring and management of complications. This can include medication to decrease brain swelling in hepatic encephalopathy or procedures to control bleeding from dilated veins.

Liver transplantation can be a lifesaving measure in acute liver failure or chronic liver disease due to DILI. While it carries significant risks, transplantation can provide a chance for recovery in patients with severe, irreversible liver damage.

Steroids’ role in DILI treatment is controversial. Some studies suggest potential benefits in specific types of drug-induced liver disease, but their routine use isn’t recommended. Decisions about steroid use should be individualized, considering the potential benefits and risks for each patient.

Drug-Induced Hepatitis List

Drug-induced hepatitis is inflammation of the liver caused by medications. It’s a type of DILI and can be caused by various drugs. Here are some commonly implicated ones:

  1. Acetaminophen: Overdose can cause severe liver damage, leading to hepatitis and acute liver failure.
  2. Isoniazid: Used for tuberculosis treatment, it can cause hepatitis, especially in older adults.
  3. Amoxicillin-clavulanate: This common antibiotic is often associated with drug-induced hepatitis.
  4. Statins: While generally safe, these cholesterol-lowering drugs can occasionally cause hepatitis.
  5. Methotrexate: Used in conditions like rheumatoid arthritis and psoriasis, it can cause liver inflammation, particularly with long-term use.
  6. Valproate: This antiepileptic medication can cause drug-induced hepatitis, especially in children and those with metabolic disorders.
  7. Halothane: This anesthetic agent can cause a severe form of hepatitis, although it’s now rarely used.
  8. Certain herbal supplements: Products like kava, comfrey, and certain traditional Chinese medicines have been linked to hepatitis.

Any drug metabolized by the liver could potentially cause hepatitis. Thus, clinicians must maintain a high suspicion in patients presenting with liver injury who are taking these or other hepatotoxic drugs.

Understanding that susceptibility to drug-induced hepatitis can vary greatly among individuals is also key. Genetics, age, sex, and pre-existing liver disease can all influence a person’s risk of developing this condition.
