Use of Thalidomide for Gastrointestinal
Angiodysplasia – Not So Uncommon Anymore
Abstract
We report a 67-year-old African American female
with extensive proximal small bowel arteriove-
nous malformations who developed GI bleed-
ing refractory to endoscopic treatments. Her GI
bleeding resolved after initiation of thalidomide.
Thalidomide is a known teratogenic drug with
suppressive action on tumor necrosis factor al-
pha and an effective inhibitor of angiogenesis,
which was shown to be efficacious in treatment
of gastrointestinal vascular malformations re-
fractory to other interventions.
colonoscopy. She reports no significant family
history. Her daily medications include amlodip-
ine/valsartan, insulin glargine, regular insulin
sliding scale, cinacalcet, sevelamer carbonate,
levothyroxine, lubiprostone, and simvastatin.
Socially, she is not currently married and denies
any smoking, alcohol, or illicit drug use history.
Per outside hospital records, esophagogastrodu-
odenoscopy (EGD) and colonoscopy showed no
obvious source of bleeding and noted only some
erosion in the stomach. Tagged RBC scan was
clindamycin and linezolid. She was transferred to
our facility for further management of GI bleed
and consideration for capsule endoscopy.
Upon arrival to our facility, patient was afebrile,
normotensive, with normal heart rate, and on
room air. Her abdomen was soft with no ten-
derness to palpation and normoactive bowel
sounds present. She had a left internal jugular
Quinton catheter in place. Capsule endoscopy
was performed, which showed multiple areas
of angioectasia and bleeding AVMs in the prox-
imal small bowel (Figure 1), and
the patient underwent single bal-
