ARTICLE HIGHLIGHTS
Research background
In solid organ transplants, one should be aware of the potential risk for tuberculosis, usually because reactivation of latent tuberculosis infection (LTBI).
Research motivation
Dealing with tuberculosis risk is especially difficult in countries with high endemic rates. In liver transplant recipients, we also have to deal with hepatotoxicity associated with the treatment regimens for LTBI.
Research objectives
The aim of this study was to evaluate the frequency of LTBI in liver transplant patients and treatment-related issues.
Research methods
This is a retrospective analysis of a cohort of cirrhotic patients aged ≥ 18 years who underwent liver transplantation at a high-complexity teaching hospital from January 2005 to December 2012. LTBI diagnosis and treatment were analyzed.
Research results
The prevalence of LTBI was lower than expected, probably due to low TST sensitivity in patients with impaired liver function. In addition, the initiation and completion of LTBI was limited by difficulties in the management of patients in the presence of elevated liver enzymes and a potential risk of hepatotoxicity.
Research conclusions
The prevalence of LTBI was lower than expected, and the initiation and completion of LTBI treatment was limited by difficulties in the management of these special patients.
Research perspectives
It is necessary to search for other criteria to indicate the treatment of LTBI for patients submitted to liver transplantation, and further research is necessary to develop an effective and well-tolerated alternative therapeutic strategy for LTBI.
