PubMed Update June - July 2015

Great stuff this time! 34 in two months.

1. Opioid Overdose Prevention Programs Providing Naloxone to Laypersons - United States, 2014.

Wheeler E, Jones TS, Gilbert MK, Davidson PJ.

MMWR Morb Mortal Wkly Rep. 2015 Jun 19;64(23):631-5.

Comment: The long-awaited sequel to 2010’s blockbuster naloxone MMWR report! 152,283 laypersons trained and 26,463 overdose reversals reported to naloxone programs through 2014.

2. Heroin-related overdose: The unexplored influences of markets, marketing and source-types in the United States.

Mars SG, Fessel JN, Bourgois P, Montero F, Karandinos G, Ciccarone D.

Soc Sci Med. 2015 Jun 30;140:44-53. doi: 10.1016/j.socscimed.2015.06.032. [Epub ahead of print]

Comment: Interesting use of qualitative data exploring the role of heroin markets on overdose risk, suggesting that factors such as open-air versus behind-closed-door markets can affect risk.

3. Risk factors for concurrent use of benzodiazepines and opioids among individuals under community corrections supervision.

Cropsey KL, Stevens EN, Valera P, Brendan Clark C, Bulls HW, Nair P, Lane PS.

Drug Alcohol Depend. 2015 Jul 10. pii: S0376-8716(15)00352-X. doi: 10.1016/j.drugalcdep.2015.06.038. [Epub ahead of print]

Comment: There’s a movement toward not prescribing opioids with benzodiazepines at all. This makes some sense from an overdose prevention perspective, however the impact of such a policy is unknown. Those who require both opioids and benzodiazepines generally have far more complex and substantial mental health challenges. Just removing one or the other of the agents may results in worsening mental health or even increased rates of self-harm. Or not. Nobody knows.

4. Drug quality assessment practices and communication of drug alerts among people who use drugs.

Soukup-Baljak Y, Greer AM, Amlani A, Sampson O, Buxton JA.

Int J Drug Policy. 2015 Jul 2. pii: S0955-3959(15)00200-5. doi: 10.1016/j.drugpo.2015.06.006. [Epub ahead of print]

Comment: This is interesting, particularly in an era of frequent high-potency batches of heroin or even pure fentanyl derivatives. Subjects recommend using words like “dangerous” or “lethal” instead of “potent” which can be misconstrued as desirable. They also emphasized timeliness. As one of the first studies to really look at this issue, this paper is well worth the read.

5. Opioid Overdose Deaths in the City and County of San Francisco: Prevalence, Distribution, and Disparities.

Visconti AJ, Santos GM, Lemos NP, Burke C, Coffin PO.

J Urban Health. 2015 Jun 16. [Epub ahead of print]

Comment: Epidemiology of opioid overdose mortality in San Francisco – the first since Pete Davidson’s seminal geocoding paper in 2003 that led SF to refocus overdose prevention efforts to the hardest hit neighborhoods. This paper documents that heroin overdose is now remarkably rare in San Francisco, although for me it raises more questions than it answers.

PubMed Update November 2014 - February 2015

Catching up on 51 papers in 4 months. Did you miss me?

1) New Drugs of Abuse.

Rech MA, Donahey E, Cappiello Dziedzic JM, Oh L, Greenhalgh E.

Pharmacotherapy. 2014 Dec 4. doi: 10.1002/phar.1522. [Epub ahead of print]

Comment: Review of management of drug toxicities among novel, synthetic compounds.

2) Police officer attitudes towards intranasal naloxone training.

Ray B, O'Donnell D, Kahre K.

Drug Alcohol Depend. 2015 Jan 1;146:107-10. doi: 10.1016/j.drugalcdep.2014.10.026. Epub 2014 Nov 8.

Comment: Police officers like being trained to carry naloxone.

3) Intranasal naloxone administration for treatment of opioid overdose.

Robinson A, Wermeling DP.

Am J Health Syst Pharm. 2014 Dec 15;71(24):2129-35. doi: 10.2146/ajhp130798.

Comment: Review of intranasal naloxone for overdose reversal.

4) Observed transition from opioid analgesic deaths toward heroin.

Dasgupta N, Creppage K, Austin A, Ringwalt C, Sanford C, Proescholdbell SK.

Drug Alcohol Depend. 2014 Dec 1;145:238-41. doi: 10.1016/j.drugalcdep.2014.10.005. Epub 2014 Oct 18.

Comment: Heroin overdoses are increasing.

5) Brief overdose education can significantly increase accurate recognition of opioid overdose amongheroin users.

Jones JD, Roux P, Stancliff S, Matthews W, Comer SD.

Int J Drug Policy. 2014 Jan;25(1):166-70. doi: 10.1016/j.drugpo.2013.05.006. Epub 2013 Jun 15.

Comment: Brief overdose training works for naloxone distribution. This is important because many places are requiring prolonged trainings that end up limiting access to those who are unable or unwilling to invest that degree of time.

6) Brief overdose education is sufficient for naloxone distribution to opioid users.

Behar E, Santos GM, Wheeler E, Rowe C, Coffin PO.

Drug Alcohol Depend. 2015 Mar 1;148:209-12. doi: 10.1016/j.drugalcdep.2014.12.009. Epub 2014 Dec 19.

Comment: Again, brief overdose training works for naloxone distribution.

PubMed Update February 2014

8 papers today, essentially about naloxone and heroin.

1) Risk of anaphylaxis in opioid dependent persons: effects of heroin versus substitution substance.

Maurer U, Kager C, Fellinger C, Loader D, Pollesböck A, Spitzer B, Jarisch R.

Subst Abuse Treat Prev Policy. 2014 Feb 27;9(1):12. [Epub ahead of print]

Comment: Seeking alternative explanations for “overdose”, the authors explored histamine levels in heroin using individuals. They found that heroin users had greater spikes in histamine levels when exposed to IV heroin compared to oral morphine. They hypothesized that this may explain why so many cases of overdose have a sublethal concentration of opioids, but this seems an overreach based on their data.

2) Effective use of naloxone among people who inject drugs in Kyrgyzstan and Tajikistan using pharmacy- and community-based distribution approaches.

Kan M, Gall JA, Latypov A, Gray R, Alisheva D, Rakhmatova K, Sadieva AS.

Int J Drug Policy. 2014 Jan 23. pii: S0955-3959(14)00008-5. doi: 10.1016/j.drugpo.2014.01.005. [Epub ahead of print]

Comment: 47 to 81% of naloxone kits given out in Kyrgyzstan and Tajikistan were used to reverse an overdose – remarkable numbers, from 3 to 5 times higher than seen in western states.

3) Norway tries naloxone in spray form to prevent deaths from drug overdose.

Hansen A.

BMJ. 2014 Feb 20;348:g1686. doi: 10.1136/bmj.g1686. No abstract available.

Comment: Naloxone in Norway.

4) Naloxone induces endoplasmic reticulum stress in PC12 cells.

Seo S, Kwon YS, Yu K, Kim SW, Kwon OY, Kang KH, Kwon K.

Mol Med Rep. 2014 Apr;9(4):1395-9. doi: 10.3892/mmr.2014.1935. Epub 2014 Feb 7.

Comment: I can only see the abstract for this one and the science is outside of my realm – I’m unable to identify anything of apparent clinical relevance.

5) Naloxone for Opioid Overdose Prevention: Pharmacists' Role in Community-Based Practice Settings.

Bailey AM, Wermeling DP.

Ann Pharmacother. 2014 Feb 12. [Epub ahead of print]

Comment: Very helpful and relevant summary of some pharmacists experience with dispensing naloxone.

6) A case of heroin induced sensorineural hearing loss.

Aulet RM, Flis D, Sillman J.

Case Rep Otolaryngol. 2014;2014:962759. doi: 10.1155/2014/962759. Epub 2014 Jan 6.

Comment: Another case of opioid overdose-related sensorineural hearing loss, which means hearing loss from the cochlea (inner ear). The authors kindly run through some theories, including hypotension (e.g. reduced blood flow to the inner ear), overstimulation of kappa opioid receptors present in the cochlea, or adulteration with an ototoxic substance such as quinine.

7) Overdose prevention in injecting opioid users: The role of substance abuse treatment and training programs.

Sarasa-Renedo A, Espelt A, Folch C, Vecino C, Majó X, Castellano Y, Casabona J, Brugal MT; Redan Study Group.

Gac Sanit. 2014 Jan 10. pii: S0213-9111(13)00227-6. doi: 10.1016/j.gaceta.2013.10.012. [Epub ahead of print]

Comment: Substance use disorder treatment programs are increasingly engaging in overdose prevention efforts – a badly needed development.

8) Commentary on Kerr et al. (2013): advertising high-potency heroin.

Dietze P.

Addiction. 2013 Jul;108(7):1277-8.

Comment: Interesting remarks by the author, suggesting that rather than advertising the high potency heroin, simply noting a spike in deaths and advertising overdose prevention/response strategies may be safer and more relevant to the target population.
