Résumé
The purpose of this study was to investigate the differences in subjective acute effects of alcohol and naltrexone among those who prefer spicy food to varying degrees. Acute biphasic alcohol effects scale (BAES), visual analogue scale for craving (VAS-C), blood alcohol concentration (BAC) and food preference scale were measured in 26 men. Repeated measures ANOVA (2 preference groupsx4 time blocks) on the stimulative subscale of BAES revealed a significant group by block interaction in naltrexone condition (N+) (P<0.001), but not in non-naltrexone condition (N-). Furthermore, repeated measures ANOVA (2 drug groupsx4 time blocks) on the stimulative subscale of BAES revealed a significant group by block interaction in strong preference for spicy food (SP) (P<0.001), but not in lesser preference for spicy food (LP). The paired t-test revealed that significant suppression of the stimulative subscale of BAES was observed at 15 min (P<0.001) and 30 min (P<0.001) after drinking when N+ compared with N- in SP. For those who prefer spicy food, the stimulative effect of acute alcohol administration was suppressed by naltrexone. This result suggests that the effect of naltrexone may vary according to spicy food preference.

A 28-year-old patient operated for laparoscopic donor nephrectomy (LDN) developed overdose effect of fentanyl leading to poor postoperative recovery. Naloxone (200 microg) treatment was used to reverse fentanyl effects, but it was associated with hypertension. The patient developed pulmonary edema after 2 hours and required overnight mechanical ventilation with positive end-expiratory pressure. Volume overload prescribed in the management of LDN to overcome the immediate poor renal graft functioning probably predisposed this healthy young patient to develop cardiac failure during sympathetic surge associated with naloxone administration. The authors feel that the reversal of overdose effect of opioid by naloxone after intravascular blood volume expansion puts the patient at risk to develop pulmonary edema.
