High-dose intravenous immune globulin (IV IgG) is currently the treatment o
f choice for patients with idiopathic thrombocytopenic purpura (ITP) who un
dergo splenectomy; however, this treatment is extremely expensive. We repor
t on 13 ITP patients with severe thrombocytopenia (< 20 x 10(9)/l) who were
prepared for laparoscopic splenectomy with a 4-day oral course of high-dos
e (40 mg/day) dexamethasone (DEX). Four patients had an excellent response
with platelet counts that increased to above 150 x 10(9)/l. Seven patients
had a good response with a platelet count that increased to between 50 and
150 x 10(9)/l (median 121 x 10(9)/l). Two patients were resistant both to D
EX and IV IgG. The operation was uneventful in all the patients, including
the 2 who had resistant ITP and were operated on while their platelet count
was very low (5 x 10(9)/l). Thus, high-dose DEX, which is an easy, effecti
ve and inexpensive treatment, is recommended for the preparation of ITP pat
ients prior to splenectomy.
