Close Correlation between Frailty and Depressive State in Chronic Liver Diseases

Antidepressants in People With Chronic Liver Disease and Depression: When Are They Warranted and How to Choose the Suitable One?

Most chronic medical illnesses are associated with significant psychiatric comorbidity, especially in the form of depression, anxiety, and suicidality. Chronic liver disease (CLD) is no exception to this and rather is placed uniquely as compared to other diseases because of its intersection with alcohol use disorder and other substance use, which in itself is a mental illness. Patients with CLD may have comorbid psychiatric illnesses; the pharmacokinetic concerns arising out of hepatic dysfunction which affects pharmacotherapy for depression and vice versa. The high prevalence of medical comorbidities with CLD may further complicate the course and outcome of depression in such patients, and diagnostic and management issues arise from special situations like transplant evaluation, alcohol use disorder, and hepatic encephalopathy or multifactorial encephalopathy seen in a disoriented or agitated patient with CLD. For this narrative review, we carried out a literature search in PubMed/PubMed Central and in Google Scholar (1980-2023) with the keywords "depression in cirrhosis", "antidepressants in liver disease", "anxiety in liver disease", "depression in liver transplantation", and "drug interactions with antidepressants". This review presents a comprehensive view of the available research on the use of antidepressants in patients with CLD, including deciding to use them, choosing the right antidepressant, risks, drug interactions, and adverse reactions to expect, and managing the same. In addition, liver transplant fitness and the overlap of hepatic encephalopathy with neuropsychiatric illness will be discussed.
