fentanyl and antiretrovirals

BACKGROUND: A remarkable reduction in AIDS-related mortality has been achieved through the widespread use of triple combination antiretroviral therapy, considerably increasing the life expectancy of people living with HIV (PLWH). However, these survival gains are now at risk in North America due to an unprecedented public health emergency: the deadly drug overdose epidemic. Drug overdoses are now the leading cause of unintentional death in British Columbia (BC), Canada and the United States due to synthetic opioids (e...

INTRODUCTION: New injectors / younger drug users are an important population to target for intervention because they are often at especially high risk of HIV and HCV infection. We examined HIV prevalence and gender differences in HIV prevalence and risk behavior among new injection-drug-users in Tallinn, Estonia. METHODS: Respondent driven sampling (RDS) interview surveys and HIV testing were conducted in Tallinn in 2009, 2011 and 2013. We classified "new injectors" as persons who reported their first injection as occurring within three years of the study interview...

Spinal epidural lipomatosis is a rare condition of adipose tissue hypertrophy in the epidural space. Through nerve root and spinal canal compression, it may lead to both sensory and motor compromise. Chronic steroid use, obesity and other metabolic derangements are known causes of spinal epidural lipomatosis. Recently, several cases have been attributed to antiretrovirals taken to treat human immunodeficiency virus, given their side effects of lipodystrophy and altered fat metabolism. We report a patient on highly active antiretroviral therapy (HAART) who developed debilitating back, hip and thigh pain during the third trimester of pregnancy that prevented ambulation...

Patient-controlled analgesia (PCA) has become standard procedure in the clinical treatment of pain. Its widespread use in patients with all kinds of diseases opens a variety of possible interactions between analgesics used for PCA and other drugs that might be administered concomitantly to the patient. Many of these drug interactions are of little clinical importance. However, some drug interactions have been reported to result in serious clinical problems. Drug interactions can either predominantly affect the pharmacokinetics or pharmacodynamics of the drug...
