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.

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.

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.

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

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.

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

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.
