Study summary

Drug-induced liver injury (DILI) is an important cause of acute liver damage that occurs when prescription medications, over-the-counter drugs, herbal products, or dietary supplements harm the liver. DILI can range from mild abnormalities in liver enzymes that cause no symptoms to severe conditions such as acute liver failure, the need for an urgent liver transplant, or death. Diagnosing DILI is often challenging because it shares symptoms with many other liver diseases, and there are currently no single specific blood tests to confirm it.

There is limited data regarding the prevalence, causative agents, and clinical outcomes of DILI among patients in Upper Egypt.

The main purpose of this study is to:

  1. Determine the hospital-based prevalence of DILI among adult patients attending Al-Rajhi Liver Hospital, Assiut University Hospitals.
  2. Identify the most common medications, herbal preparations, and supplements causing liver injury.
  3. Categorize the patterns of liver injury (hepatocellular, cholestatic, or mixed) using standardized biochemical calculations (R-ratio).
  4. Evaluate patient outcomes and identify clinical and laboratory factors that predict unfavorable outcomes, such as acute liver failure, liver transplantation, or death.

The study is an observational study conducted over a two-year period using two approaches:

  • A retrospective chart review of adult patients diagnosed with DILI during the first year.
  • A prospective follow-up of consecutive adult patients who present with DILI during the second year.

Participants will receive standard medical care as directed by their treating physicians. Routine medical data, laboratory tests, imaging results, and treatment details will be recorded and analyzed to help improve the early detection, prevention, and management of DILI in clinical practice.

Study population

Adult patients (aged 18 years or older) presenting to or admitted to Al-Rajhi Liver Hospital, Assiut University Hospitals, Assiut, Egypt, who fulfill the predefined clinical and biochemical criteria for drug-induced liver injury (DILI) following exposure to a suspected prescription drug, herbal preparation, or dietary supplement.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adult patients aged 18 years or older.
  • Patients presenting to or admitted to Al-Rajhi Liver Hospital during the study period.
  • Patients fulfilling the predefined biochemical and clinical criteria for drug-induced liver injury (DILI):

    • (ALT) >= 5 times the (ULN); or
    • Alkaline phosphatase (ALP) >= 2 times the ULN (particularly when accompanied by elevated gamma-glutamyl transferase [GGT] and in the absence of a known bone source); or
    • ALT >= 3 times the ULN with simultaneous total > 2 times the ULN.
  • Documented exposure to a suspected medication, herbal preparation, or dietary supplement preceding the onset of liver injury, with a compatible temporal relationship.
  • For the retrospective cohort: availability of adequate medical records to establish the diagnosis of DILI and assess clinical outcomes.
  • For the prospective cohort: provision of for study participation and follow-up (by the patient or a legally authorized representative).

Exclusion criteria

Exclusion Criteria:

  • Patients younger than 18 years
  • Patients in whom an alternative etiology of acute liver injury is clearly established (e.g., acute viral hepatitis, hepatitis, biliary obstruction, ischemic/hypoxic hepatitis) and DILI is considered unlikely
  • Patients with insufficient clinical or laboratory data to verify whether diagnostic criteria for DILI are fulfilled
  • Patients in the retrospective cohort with inadequate outcome records where assessment of the primary clinical endpoint is not possible
  • Patients (or their legal representatives) who decline participation in the prospective cohort
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Groups and cohorts

  • Retrospective DILI Cohort

    Eligible adult patients (aged 18 years or older) evaluated at Al-Rajhi Liver Hospital during the first year of the study period who fulfill the predefined clinical and biochemical criteria for drug-induced liver injury (DILI), identified via medical record review.

  • Prospective DILI Cohort

    Consecutive eligible adult patients (aged 18 years or older) presenting to or admitted to Al-Rajhi Liver Hospital during the second year of the study period who fulfill the predefined clinical and biochemical criteria for drug-induced liver injury (DILI) and are followed prospectively.

  1. Proportion of Patients With Unfavorable DILI Outcomes

    Proportion of patients with drug-induced liver injury who develop a composite unfavorable outcome, defined as acute liver failure (acute liver injury with hepatic coagulopathy and clinically apparent hepatic encephalopathy without pre-existing severe chronic liver disease), liver transplantation, or death attributable to severe DILI.

    Time frame: Up to 1 year

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 21, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
