AB OBJECTIVE: Patients infected with human immunodeficiency virus (HIV)
frecuently have aphtous ulcers (AO) of the oral mucosa. Successful use
of pentoxifylline has been reported recently in the treatment of AO in
general population. The purpose of this study was to evaluate the
efficacy of pentoxifylline in HIV patients with AO. METHODS: Four
non-selected patients (3 men, 1 woman) with HIV infection and recurrent
AO (minimum, three episodes in one year) were enrolled in this study.
Diagnosis of HIV-associated AO should be considered after repeated
negative cultures and citologies for infectious agents. They started
medication in a moment of an acute outbreak. Patients received
pentoxifylline 400 mg/day, three times a day for 4 months. RESULTS:
Three of our four patients responded to treatment. In this group,
complete reepithelialization was noted after 1 to 2 weeks and there has
been no relapse during a follow-up of four months. One patient showed
resistence of AO to pentoxifylline, so the medication was stopped two
months after treatment onset. No toxicity or morbidity was noted.
DISCUSSION AND CONCLUSIONS: Successful use of thalidomide has been
reported in the treatment of AO in HIV patients, but this therapy has
considerable potential toxicity, particularly neuropathy. The mode of
action of thalidomide seems to be related with inhibition of tumor
necrosis factor (TNF-alpha). Pentoxifylline has recently been
demonstrated to inhibit TNF-alpha too. Our findings suggest that a
double-blind controlled trial of pentoxifylline in HIV patients with AO
should be undertaken.
