Evaluation of Long Haul COVID-19 and Vaccine Immunogenicity in Patients With Liver Disease

The project is essential to understand the impact of the COVID-19 pandemic in patients with Chronic Liver Disease (CLD). The impact has been felt due to direct risk of COVID infection in self, or in caregivers, lack of access to services during lockdown, interruptions in transplant listing and waitlist mortality. Briefly, the following points will be focused during the study. 1. Long haul COVID-19 related symptoms. 2. Impact on health and delay in interventions or drug therapy due to interruption of physical outpatient services. 3. Impact on emergency admissions due to refractory ascites, new decompensation, variceal bleeding etc 4. Impact on delayed transplant listing and waitlist mortality 5. Impact on post-transplant patients with lack of access to drug monitoring/ physical OPD 6. Impact on delay in interventions due to hepatobiliary malignancy. 7. Effects of COVID-19 infection, vaccination (single dose, two doses) and no vaccination and protective antibody levels in patients with chronic liver disease and post-transplant recipients. 8. Determination of dose protocol and need for booster vaccination in patients with CLD and post liver transplant recipients.
