buprenorphine and Cushing-Syndrome

Opioid abuse is common in Iran. In 2005, a new version of locally produced illicit opioid vials, so called Norgesic, appeared in the illicit market, which gained popularity rapidly and led to an improvement of stigmatizing the general appearance of dependent cases. Later, some cases suffered Cushing's-like problems. A prospective case series was designed to evaluate 18 Norgesic-dependent subjects who volunteered for abstinence therapy in a rehabilitation clinic from November 1, 2005, to December 30, 2005. In this study, we aimed to describe the clinical and paraclinical findings in detail and define the potential determinants of this Cushing's syndrome outbreak. History, physical examination, plasma cortisol level, and urine screen tests were used to describe the patients. All subjects were male with a mean (SEM) age of 29.8 +/- 1.6 years. The opioid-dependence period was 8.4 +/-0.9 years. In an average of 4.7 +/- 0.3 months, subjects increased their usage to 5.5 +/- 0.5 vials a day. Patients claimed to gain weight. Striae were seen in 38.9%, previously documented psychological problems in 33.3%, weakness in 27.8%, high systolic blood pressure in 22.2%, moon face in 16.7%, hirsutism in 11.1%, extensive dermal infection in 11.1%, gynecomastia in 5.6%, back pain in 5.6%, insomnia in 5.6%, and lack of potency in 5.6%. Their cortisol level, on average, was 4.8 +/- 1.1 microg/dL. Hepatitis C virus was positive in 22.2%. Urine-screening tests were positive for morphine and negative for buprenorphine. In conclusion, these new vials contain steroids as well as opioids. This combination could be more dangerous than opioids themselves.

Despite the widespread medical use of glucocorticoids, reports of factitious administration of these hormones have been uncommon. We herein report an outbreak of Cushing's syndrome in Tehran among the addicts using Tamgesic (a brand of Buprenorphine) to help them through the narcotic withdrawal stage, without knowledge of the glucocorticoid content of the black-market drug.. Case histories of 19 patients with a final diagnosis of iatrogenic Cushing's syndrome were reviewed. Liquid chromatography/mass spectrometry (LC-Mass) method was used to evaluate glucocorticoid existence in the brand. High performance liquid chromatography was used to determine plasma dexamethasone level.. No buprenorphine was present in the vials. Each Tamgesic vial contained 0.4 mg of Dexamethasone disodium phosphate; Heroin was also found in them. The duration of injection abuse and the total dexamethasone intake was 4.5 (1-18) months and 2.6 (0.8-8) mg/day, respectively. Median plasma dexamethasone concentration was 5.8 nmol/l, with a range of 5-8.7. Physical findings of the cases were not different from those of the classic endogenous Cushing's syndrome but their serum cortisol and urinary free cortisol were suppressed. Severe life-threatening complications were demonstrated in five cases.. Surreptitious use of steroids resulting in Cushing's syndrome may be more common in opium addicts; a high degree of suspicion is needed to uncover this disorder. Whenever facing a cushingoid appearance in addicts, the possibility of using black market drugs with corticosteroid contents should be kept in mind.
