Abstract
Background
Gastrointestinal bleeding (GIB) is a complication reported in patients post left ventricular assist device (LVAD) implantation that is associated with high mortality rates. Thalidomide is an anti-angiogenic compound that may offer a potential option for management of refractory LVAD-related GIB.
Methods
A single-center, retrospective review was conducted from January 2009 to October 2016 at a tertiary cardiology center. It included LVAD patients initiated on thalidomide for refractory GIB.
Results
All patients (n = 11) were started on thalidomide 50 mg nocte and there was resolution of GIB in all patients except one (90.9%) during initial thalidomide treatment.
The median duration of thalidomide therapy was 98 days (interquartile range: 34–215). The dose of thalidomide was reduced for 2 patients due to adverse effects. Thalidomide therapy was discontinued in 6 patients due to cessation of GIB (n = 4) and adverse effects (n = 2). Reported adverse effects included LVAD thrombosis (n = 2), somnolence (n = 1), neuropathy (n = 1), constipation (n = 1), and transaminitis (n = 1).
Recurrent GIB occurred in 4 patients (45.4%) post-discontinuation of thalidomide therapy, which led to the re-initiation of therapy.
Conclusions
Thalidomide appears to be a safe and effective option for management of refractory LVAD-related GIB. Monitoring for recurrent GIB should be performed closely following cessation of thalidomide therapy.
