A Real World Study of Polyene Phosphatidylcholine Injection for the Prevention and Treatment of DILI in Patients With Malignant Hematological Diseases

This is a retrospective, multicenter real-world observational study. Its main goal is to find out if Polyene Phosphatidylcholine Injection works to treat drug-induced liver injury (DILI) in adults with hematologic malignancies, and to check if the drug is safe.

It also aims to answer these key questions:

Does Polyene Phosphatidylcholine Injection help prevent DILI in people with hematologic malignancies? How effective and safe are different combinations of Polyene Phosphatidylcholine Injection with other liver-protective drugs for DILI? Which DILI treatment plan offers better value for money?

Who can take part?

Participants must meet all these criteria:

18 years or older (no gender restriction) Diagnosed with a hematologic malignancy (such as leukemia, lymphoma, or multiple myeloma) Received at least one cycle of chemotherapy that may harm the liver Used Polyene Phosphatidylcholine Injection to treat or prevent DILI (alone or with one/two specific liver-protective drugs: Magnesium Isoglycyrrhizinate Injection, Glutathione Injection, Ademetionine 1,4-Butanedisulfonate Injection/Tablets, Ursodeoxycholic Acid Oral Formulation, or Bicyclol Tablets) Had liver function tests within 7 days before starting treatment and at least once after starting treatment

What will the study involve?

Researchers will look back at medical records of eligible participants treated on or before November 30, 2025. They will collect and analyze:

Participants' basic information (age, gender) and disease details Details about Polyene Phosphatidylcholine Injection use (dose, frequency, duration) Liver function test results (including alanine aminotransferase [ALT, a liver enzyme that rises when the liver is injured], aspartate aminotransferase [AST], total bilirubin [TBIL], and other related indicators) at different time points (3 days, 7 days, 14 days, 21 days, 30 days, 60 days) after starting treatment Any unwanted health issues (adverse events, AEs) during treatment and how they were managed Costs related to treatment (drug fees, test fees, AE management fees)

What are the key things researchers will measure? Main measure: How well ALT levels improve 7 days after starting Polyene Phosphatidylcholine Injection (defined as ALT dropping by more than 50% or returning to normal)

Secondary measures:

Improvement in liver function indicators at other time points (3 days, 14 days, 21 days, 30 days, 60 days) How well the drug prevents DILI (how often DILI occurs and how severe it is) Differences in effectiveness and safety between different drug combinations Which treatment plan is more cost-effective
