Clinical experience with desvenlafaxine in treatment of pain associated with diabetic peripheral neuropathy.
To assess the safety and efficacy of the serotonin-norepinephrine reuptake inhibitor desvenlafaxine in adults with painful diabetic peripheral neuropathy (DPN). ⋯ Desvenlafaxine was effective in relieving pain associated with DPN at doses of 200 and 400 mg/day, and improved activity impairment at all doses assessed. Desvenlafaxine was generally well-tolerated in the short-term and long-term studies.

An approach to identify microRNAs involved in neuropathic pain following a peripheral nerve injury.
Peripheral nerve injury alters the expression of hundreds of proteins in dorsal root ganglia (DRG). Targeting some of these proteins has led to successful treatments for acute pain, but not for sustained post-operative neuropathic pain. The latter may require targeting multiple proteins. ⋯ Bioinformatic analysis of how these miRs could affect the expression of some ion channels supports the view that, following a peripheral nerve injury, the increase of the seven miRs may contribute to the recovery from neuropathic pain while the decrease of four of them may contribute to the development of chronic neuropathic pain. The approach used resulted in the identification of a small number of potentially neuropathic pain relevant miRs. Additional studies are required to investigate whether manipulating the expression of the identified miRs in primary sensory neurons can prevent or ameliorate chronic neuropathic pain following peripheral nerve injuries.

Pregabalin is an antagonist of voltage gated Ca2+ channels and specifically binds to alpha-2-delta subunit to produce antiepileptic and analgesic actions. It successfully alleviates the symptoms of various types of neuropathic pain and presents itself as a first line therapeutic agent with remarkable safety and efficacy. ⋯ Preclinical studies employing pregabalin in different neuropathic pain models have explored various molecular targets and the signaling systems including Ca2+ channel-mediated neurotransmitter release, activation of excitatory amino acid transporters (EAATs), potassium channels and inhibition of pathways involving inflammatory mediators. The present review summarizes the important aspects of pregabalin as analgesic in preclinical and clinical studies as well as focuses on the possible mechanisms.

Anticonvulsants are increasingly being used in the symptomatic management of several neuropathic pain disorders. The present observational study was designed to evaluate the efficacy, tolerability, and quality of life (QoL) of carbamazepine use for 12 weeks in patients with painful diabetic neuropathy, in Pakistan. ⋯ In this real-life experience study, carbamazepine, when prescribed for 12 weeks to adult diabetic patients suffering from neuropathic pain, showed pain-relief effect, with reduced mean pain severity and mean pain interference scores and with improved QoL and good tolerability profile.

Unrelieved neuropathic pain continues to be a substantial health problem in a cancer patient arises either due to disease itself or its treatment. Review of literature showed that neuropathic pain has high prevalence rate, greater severity and analgesic requirement with worse quality of life. Underreporting by patient and under treatment by physician is an important causative factor of indefinite persistence of neuropathic pain. ⋯ To find out the burden and estimation of resource generation of this widely recognized problem, accurate establishment of incidence, prevalence, severity, and effectiveness of treatment is quite mandatory. Complex phenomenon of neuropathic pain abolishes establishment of early diagnosis and accurate etiology of this symptom, emphasizes the need of sensitive and reliable clinical grading scale, international classification system and validated diagnostic tools that correspond with clinical assessment. Multiple studies towards this direction has been culminated and some are still going on, though the data and literature is very scant and require further research for the complete evaluation of neuropathic pain.
