BACKGROUND: Despite revised guidelines that no longer exclude people who inject drugs (PWID) from treatment for hepatitis C virus (HCV) infection, many clinicians are reluctant to treat recent PWID. This study aimed to evaluate the efficacy of sofosbuvir and velpatasvir therapy in people with chronic HCV infection and recent injection drug use. METHODS: In this open-label, single-arm phase 4 trial (SIMPLIFY), we recruited participants with recent injection drug use (past 6 months) and chronic HCV genotype 1-6 infection from seven countries (19 sites)...

Background: Opioid substitution therapy (OST) is an evidence-based intervention for opiate-dependent persons that replaces illicit drug use with medically prescribed, orally administered opiates such as buprenorphine and methadone. OST reduces HIV risk behaviors and harms associated with injecting opioid. Most of the evidence for OST effectiveness has been generated in middle- and high-income countries where programs are mostly located in dedicated health-care settings; evidence regarding the outcomes of OST programs in low-income countries where OST is often provided in grassroots settings such as drop-in centers is limited...

RATIONALE: Consideration by the US Drug Enforcement Administration and Food and Drug Administration of placing kratom into Schedule I of the Controlled Substances Act (CSA) requires its evaluation of abuse potential in the context of public health. OBJECTIVE: The objective of the study is to provide a review of kratom abuse potential and its evaluation according to the 8 factors of the CSA. RESULTS: Kratom leaves and extracts have been used for centuries in Southeast Asia and elsewhere to manage pain and other disorders and, by mid-twentieth century, to manage opioid withdrawal...

BACKGROUND: Kratom (Mitragyna speciosa) is a psychoactive plant native to Southeastern Asia that is receiving increased international attention as a potential therapeutic agent. While much of the limited scientific research on kratom is focused on its analgesic potential, kratom use also has important risks and benefits in the domain of mental health. METHODS: We conducted a comprehensive systematic review of all studies on kratom use and mental health published between January 1960 and July 2017...

In June 2013, the European Medicine Agency recommended limiting codeine use in paediatric patients, creating a void in managing moderate pain. We reviewed literature published in English (1985-June 2017) on the pharmacokinetic, pharmacodynamic and safety profile of ketorolac, a possible substitute for codeine and opioids, for treating moderate to severe pain. We found that gastrointestinal side effects were mainly reported with prolonged use, significant bleeding was reported in adenotonsillectomies and adverse renal effects appeared to be limited to patients with specific coexisting risk factors...

This article concentrates on methadone maintenance as a normalizer for the impairments of opioid addiction, and the misunderstandings of it as a substitute for heroin that continues an opiate addiction. Methadone treatment was developed by Drs. Dole, Nyswander, and Kreek. Their cutting-edge theory transformed the way that opioid addiction is perceived and their work changed methadone from a narcotic to withdraw addicts to a medication that is a maintenance normalizer for a chronic condition. Their extensive research involved the physiological and sociological normalizing effects of methadone and medical safety of the medication (Dole & Nyswander, 1967)...

Data at the individual-level provide evidence that opioid substitution treatment (OST) programs protect against mortality for opioid dependent populations. Prior research has not examined the merits of national implementation of opioid substitution programs for reducing mortality at the country-level. This study elucidates longitudinal associations between country-level implementation of opioid substitution treatment programs on mortality rates of drug related deaths (DRD) from 1995 to 2013 in 30 European nations...

Pain management in end stage renal disease (ESRD) patients is a complex and challenging task to accomplish, and effective pain and symptom control improves quality of life. Pain is prevalent in more than 50% of hemodialysis patients and up to 75% of these patients are treated ineffectively due to its poor recognition by providers. A good history for PQRST factors and intensity assessment using visual analog scale are the initial steps in the management of pain followed by involvement of palliative care, patient and family counseling, discussion of treatment options, and correction of reversible causes...

Novel substituted amino acid tethered norsufentanil derivatives were synthesized by the four-component Ugi reaction. Norsufentanil was reacted with succinic anhydride to produce the corresponding carboxylic acid. The resulting carboxylic acid has undergone a multicomponent reaction with different aldehydes, amines, and isocyanides to produce a library of the desired compounds. In all cases, amide bond rotation was observed in the NMR spectra. In vivo analgesic activity of the synthesized compounds was evaluated by a tail flick test...

So far, only three small outdated studies have investigated hepatitis C virus (HCV) incidence and risk factors among illicit drug users (DUs) in Italy. Thus, during 2007-2010, we conducted a prospective cohort study among DUs attending 17 Italian rehabilitation centers serving urban areas. Two hundred eighty-four HCV-uninfected DUs were prospectively followed by interview and anti-HCV antibody and RNA testing every 6 months. Incidence was calculated using the person-years method. Infection predictors were assessed by time-dependent Cox analysis...

BACKGROUND: In Switzerland, intravenous drug use accounts for the majority of hepatitis C virus (HCV) infections. Early HCV treatment prevents further transmissions and reduces morbidity and mortality due to decompensated liver cirrhosis and hepatocellular carcinoma. Nevertheless, patients in drug substitution programmes are often insufficiently screened and treated. AIM: The aim was to compare the current state of HCV management in centralised and decentralised drug substitution programmes of the canton Aargau...

The emergence of effective direct-acting antiviral (DAA) agents has reignited discussion over hepatitis C elimination potential in the United States. Eliminating hepatitis C will require a critical examination regarding technical feasibility, economic considerations, and social/political attention. Tremendous advancement has been made in recent years with the availability of sensitive diagnostic tests and highly effective DAAs capable of achieving sustained viral response (SVR) in more than 95% of patients...

Francina Fonseca, Marta Torrens
The efficacy of methadone maintenance treatment (MMT) in opioid use disorder is well established but responses vary. The influence of methadone pharmacodynamics and pharmacokinetics on dose requirements and program outcomes remains controversial despite the increasing number of studies evaluating genetic influences on response to methadone treatment. Furthermore, patients require different doses (usually between 60 and 100 mg/day), and there are no clear data on a plasma concentration associated with treatment success...

BACKGROUND: Quality of life (QOL) of patients in opioid substitution treatment (OST) is increasingly being addressed in research. However, no disease- or treatment-specific instrument is available to assess the QOL of this target population. The purpose of this project was to develop the first QOL instrument for OST patients. METHODS: Focus groups with 60 OST patients were analyzed using thematic analysis to elicit key QOL themes as perceived by patients. Identified themes were developed into items and refined through pilot testing and cognitive debriefing...

Late diagnosis of HIV infection can be fatal because it favors the appearance of opportunistic infections whose management requires the use of several molecules which can cause drug interactions. We report the case of a 45-year old female patient under heroin substitution treatment, using methadone and with HIV1 under antiretroviral treatment. This patient had nonspecific pulmonary appearance associated with dry nagging cough and progressive dyspnea evolving in a feverish context. Moreover, clinical examination showed left lower limb lymphedema with painless angiomatous nodules evolving over three years associated with plaques, angiomatous nodules occurred more recently at the level of the anterior face of the thorax...

Post-traumatic stress disorder (PTSD) is predominant amongst individuals addicted to opioids and obscures the course of illness and the treatment outcome. We report the case of a patient with major depressive disorder and opioid dependence, who experienced post-traumatic stress disorder symptoms during a recent visit to the inpatient unit. The similarity of symptoms between post-traumatic stress disorder and opioid dependence is so high that, sometimes, it is a challenge to differentiate between these conditions...

Rossella De Marco, Luca Gentilucci
Recently, a new family of opioid peptides containing tryptophan came to the spotlight for the absence of the fundamental protonable tyramine 'message' pharmacophore. Structure-activity relationship investigations led to diverse compounds, characterized by different selectivity profiles and agonist or antagonist effects. Substitution at the indole of Trp clearly impacted peripheral/central antinociceptivity. These peculiarities prompted to gather all the compounds in a new class, and to coin the definition 'Tryptophan-Containing Non-Cationizable Opioid Peptides', in short 'TryCoNCOPs'...
