A retrospective study of the correlation between herpes zoster neuralgia and the serum neuron-specific enolase level in the largest dermatological hospital in Zhejiang province, China

We studied the changes and clinical significance of the serum neuron-specific enolase (NSE) level in peripheral blood of patients with post-herpetic neuralgia (PHN). Material and methodsPatients with PHN were divided into a mild PHN group and a severe PHN group according to their scores on a 100-point Likert scale representing the degree of neuralgia. NSE levels in neuralgia patients and healthy volunteers were then compared by t-test. Receiver operating characteristic curve analysis was performed to evaluate the diagnostic efficiency of NSE for PHN. The correlation between NSE level and Likert scale score after treatment was analyzed. ResultsNSE levels in PHN patients were higher than those in the healthy volunteers. Patients in the severe PHN group had higher NSE levels than those in the mild PHN group. NSE level at admission was associated with the Likert scale score recorded on the 14th day of treatment (136.1 +/- 32.81 vs. 87.53 +/- 16.23 pg/mL) (P < 0.05). The ROC curve of NSE levels for PHN is shown that the area was 0.8713 (95% confidence interval, 0.7861-0.9564; p < 0.0001). ConclusionsThere was a correlation between NSE and PHN, in that the NSE level positively correlated with the short-term prognosis of patients with PHN.

Automated summary

The study found that serum NSE levels were significantly higher in patients with post-herpetic neuralgia compared to healthy volunteers, with higher levels seen in the severe PHN group. There was a positive correlation between NSE levels and short-term prognosis in patients with PHN after treatment.
