Hiccups, or singultus, are involuntary spasms of the diaphragm and in-
tercostal muscles causing sudden inspiration and a characteristic sound.
They are usually benign and self-resolving. However, in some cases
chronic or recurrent hiccups are troublesome for the patient as well as

conditions leading to persistent or repeated hiccups (1, 2, 4^6).
A cadaveric kidney was transplanted into a 44 -year-old man. His immu-
nosuppressive regimen included a standardized protocol with steroids,
cyclosporine, and mycophenolate mofetil. The postoperative course was
characterized by primary graft function without any complications ex-
cept for recurring hiccup episodes that began immediately after the pa-
tient woke up from anesthesia. These hiccups responded to treatment
with p.o. metoclopramide, and they were not severe. Presentation and
course suggested a medication-induced etiology related to steroid induc-

The start of hiccups immediately after transplantation leads us to sus-

quired nosocomial pleuropneumonia with no other agent identi¢ed

rated. A computed tomography scan revealed an abscess in the right
lower pulmonary lobe. At this time, the patient again reported new epi-
sodes of hiccups that became more and more severe. The abscess was
successfully removed by a thoracotomy, after which the patient’s status
improved rapidly and the hiccups ¢nally disappeared.

Few studies have been published about hiccups in transplant patients.

words ‘hiccups’ and ‘transplantation.’ F|ve of these articles included pa-
