valproic acid and Neuralgia, Postherpetic

valproic acid has been researched along with Neuralgia, Postherpetic in 1 studies

Valproic Acid: A fatty acid with anticonvulsant and anti-manic properties that is used in the treatment of EPILEPSY and BIPOLAR DISORDER. The mechanisms of its therapeutic actions are not well understood. It may act by increasing GAMMA-AMINOBUTYRIC ACID levels in the brain or by altering the properties of VOLTAGE-GATED SODIUM CHANNELS.
valproic acid : A branched-chain saturated fatty acid that comprises of a propyl substituent on a pentanoic acid stem.

Neuralgia, Postherpetic: Pain in nerves, frequently involving facial SKIN, resulting from the activation the latent varicella-zoster virus (HERPESVIRUS 3, HUMAN). The two forms of the condition preceding the pain are HERPES ZOSTER OTICUS; and HERPES ZOSTER OPHTHALMICUS. Following the healing of the rashes and blisters, the pain sometimes persists.

Trial Overview

Trial Outcomes

Change in Self-Reported Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale (S-LANSS)

The S-LANSS is a self-reported version of the Leeds Assessment of Neuropathic Symptoms and Signs pain scale. It aims to differentiate neuropathic pain from somatic or nociceptive pain. We will analyze the change in numeric average pain score during the past week (range from 0-10) from baseline. Higher scores indicate greater pain. (NCT01928849)
Timeframe: Assessments at enrollment and 3 months or time of final adjudication assessment (up to 6 months)

Number of Patients With Chronic Post-amputation Pain

The primary endpoint is the incidence of chronic pain after surgery. The study team will use the average pain score over the past week as noted on the Self-Reported Leeds Assessment of Neuropathic Symptoms and Signs pain scale (S-LANSS) for the assessment of pain, and define chronic pain as a score greater than or equal to 3. (NCT01928849)
Timeframe: 3 months or time of final adjudication assessment, up to 6 months

Brief Pain Inventory (BPI) Short Form Score

The BPI short form is a multidimensional patient-completed measure that assesses the sensory component of pain intensity. We will analyze the change in average pain score question (ranges 0-10) and the sum of the 7 interference questions (total range 0-70) from baseline. Higher score indicates greater pain and interference. (NCT01928849)
Timeframe: Assessments at enrollment and 3 months or time of final adjudication assessment (up to 6 months)

Defense and Veterans Pain Rating Scale (DVPRS) Score

The DVPRS is a pain assessment tool developed by the military in an effort to improve reliability and interpretability of pain assessment in the military population. It has been found to be an effective and valid tool in this population. We will analyze the change in numeric pain response (range 0-10) and the sum of the four supplemental questions (range 0-40) from baseline. Higher scores indicate greater pain and functional limitations. (NCT01928849)
Timeframe: Assessments at enrollment and 3 months or time of final adjudication assessment (up to 6 months)

Effect on Analgesic Requirement

The effect of study drug on perioperative analgesic consumption and corresponding analysis of pain/sedation scales. Outcome defined as total opioid consumption (mg) during each 24-hour periods following surgery. (NCT01928849)
Timeframe: Assessments during hospitalization (0-24 hours and 24-48 hours post-surgery)

Incidence of Pain Sub-types

The incidence of neuropathic limb or post-amputation pain sub-types as defined by adjudication classification at each assessment time point. (NCT01928849)
Timeframe: Assessments at enrollment and 3 months or time of final adjudication assessment (up to 6 months)

Richmond Agitation-Sedation Scale (RASS)

The RASS is a commonly used, valid and reliable assessment tool for use in hospitalized patients. Validity testing reveals good inter-rater reliability among medical, surgical, and intensive care units. We will analyze the numeric score at each assessment (range -5 (unarousable) to 4 (combative)). (NCT01928849)
Timeframe: during hospitalization (0-24 hours and 24-48 hours post-surgery)
