Registry-based Study in Patients With Hepatitis D Virus (HDV) Infection in China

Not yet recruiting
Conditions
Hepatitis D
Registration Number
NCT05451082
Lead Sponsor
Lai Wei
Brief Summary

This is a retrospective, prospective, noninterventive, multicenter registry study. Patients diagnosed with HDV infection (based on positive HDV RNA) were included in this study and were followed up for at least 5 years to evaluate their disease progression and clinical outcomes (including death, liver transplantation, hepatocellular carcinoma \[hcc\], liver decompensation, and cirrhosis) during the 5-year follow-up period. All patients were followed up at least once a year after they were included in the study.

It was in 2016 HDV infection first reported in China. Since January 1, 2016, all patients diagnosed with HDV infection can be enrolled in this study and evidence confirming the diagnosis (including but not limited to HDV RNA test reports and medical records, etc.) must be delivered. The main test results (including serum HDV RNA, ALT, and tests to determine the presence of liver cirrhosis, decompensation of liver function, and liver cancer such as B-ultrasound and FibroScan) of these patients each year from diagnosis to enrollment should be collected and filled in the case report form (CRF).

Follow-up data of patients with serum anti-HDV positive and HDV RNA negative can be recorded and followed up on this platform, with informed consent of the patients is required. Patients whose serum HBV RNA turn positive during the follow-up period will be included in the follow-up cohort of the study.

Combined response means HDV RNA \<LLOQ and ALT\<ULN

Serum albumin levels concentration levels of patients infected with HDV5 years

HDV means hepaitis D virus

The incidence of death of chronic HDV-infected patients with persistently normal ALT5 years

HDV means hepaitis D virus, ALT means alanine aminotransferase

The incidence of cirrhosis of chronic HDV-infected patients with persistently normal ALT5 years

HDV means hepaitis D virus, ALT means alanine aminotransferase

The proportion of patients with HDV RNA negative conversion of patients receiving antiviral therapies5 years

HDV RNA negative conversion means HDV RNA\< lower limit of quantification(LLOQ)

Child-Pugh scores of patients infected with HDV5 years

The Child-Pugh classification is a universal scoring system of the degree of liver failure in patients with cirrhosis. Variables measured by this system include ascites, encephalopathy, serum albumin, bilirubin, and prothrombin time. Traditionally, the Child-Pugh class (A, B, or C) has been used as a predictive index for operative mortality rate in adult patients undergoing portosystemic shunting procedures. The estimated 1- and 5-year survival rates are 95% and 75% for patients with Child-Pugh class B, and 85% and 50% for patients with Child-Pugh class C.

The incidence of liver decompensation of chronic HDV-infected patients with persistently normal ALT5 years

HDV means hepaitis D virus, ALT means alanine aminotransferase

Number of patients with abnormal laboratory values and/or adverse events that are related to antiviral treatment5 years

Number of patients with adverse events, sever adverse events, abnormal laboratory parameters, and drug combinations
