It truly is probable that our outcome may be a falsepositive association partly because of limitation in sample size. Therefore, our study could possibly be considered explorative in nature and it would require replication by other investigators. Nevertheless, our final results can be regarded as as a basis for further bigger scale study.patientstherapy. There’s also the possibility that heightened discomfort sensitivity is often a result of your prolonged opioid use itself or opioidinduced hyperalgesia. The heightened pain sensitivity is usually a form of latent hyperalgesia to chronic opioid misuse, and subsequent methadone therapy doesn’t exacerbate hyperalgesia but does not make it worse either Some limitations to this study need to be highlighted. You will find quite a few OPRM polymorphisms (including rs, rs, rs, rs, rs, rs, rs, rs, rs, rs, and rs) but we only studied two popular variants. Only Malay males were incorporated but we aimed to lessen the confounding effects of gender and ethnicity on cold discomfort response . Additionally, Malay males are the majority of opioiddependent individuals on methadone remedy in Malaysia.
