Study summary

Hepatitis is an inflammatory condition of the liver that has emerged as a significant global health concern due to its widespread prevalence.

Data on ursodeoxycholic acid in acute viral hepatitis remain limited. Some studies suggest its positive effect in cholestatic phase of viral hepatitis. UDCA may reduce cholestatic symptoms like jaundice and pruritus potentially shortening hospital stay and improving patient outcomes. However, robust clinical data supporting its routine use in acute viral hepatitis are lacking, and current treatment remains largely supportive. Given the high burden of acute viral hepatitis in our region and the potential for UDCA to improve cholestatic phase of AVH there is a clear need for well-designed clinical studies evaluating its therapeutic role. This study aims to evaluate the role of oral ursodeoxycholic acid in biochemical recovery of patients with acute viral hepatitis. If positive role is confirmed, it will be incorporated in standard treatment and if no role is found unnecessary use will be discouraged.

Null Hypothesis (H₀):

Oral ursodeoxycholic acid has no significant effect on the bilirubin levels of patients with acute viral hepatitis.

H₀: There is no statistically significant difference in bilirubin levels between patients receiving ursodeoxycholic acid and those receiving supportive care alone.

Alternative Hypothesis (H₁):

Oral ursodeoxycholic acid reduces bilirubin levels in patients with acute viral hepatitis. H₁: There is statistically significant difference in bilirubin levels between patients receiving ursodeoxycholic acid and those receiving supportive care alone.

Read the detailed description

Study design: A Quasi-experimental design There is an intervention group (receiving UDCA + standard care) and a control group (receiving standard care only) Study Setting: Medicine department of Combined Military Hospital, Malir, Karachi Study Duration: 6 months Sampling Technique: Non probability consecutive sampling technique

Sample Size:

Open Epi version 3, was used to calculate the sample size with a two-sided 95% confidence interval and 80% power. This was based on an expected mean difference of 0.3 mg/dL in bilirubin levels between the treatment group (mean = 4.1 mg/dL, SD = 0.5) and the control group (mean = 3.8 mg/dL, SD = 0.5) (6), a minimum of 44 participants per group was calculated to detect this difference, assuming equal variances and group sizes. The total sample size is calculated to be 88 (total N = 88), with 44 participants in each group.

Since the total estimated number of eligible admissions during the study period was 200 and the required sample size was 88, a sampling interval (k) of approximately 2 was calculated (k = 200/88 ≈ 2). A random starting point was selected to avoid periodic bias, and thereafter every 2nd eligible patient was included until the desired sample size was achieved.

Inclusion Criteria All patients of either gender, aged >18 years to 50 years with acute viral hepatitis are included.

Exclusion Criteria Patients having Hepatitis B, C, hepatocellular carcinoma, primary biliary cholangitis, choldocholithiasis and patients having normal bilirubin levels with AVH were excluded.

Terms in these criteria, in plain language(2)

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.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

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.

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 Apr 13, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
