Risk Factors for Poor Pain Control in Zoster-Associated Pain: A Retrospective Study

INTRODUCTION

The objective was to investigate the risk factors for poor pain control in patients with herpes zoster (HZ)-associated neuropathic pain treated with drugs combined with nerve block therapy. Neuropathic pain commonly follows HZ. Nerve block therapy is the most commonly used clinical treatment for such pain, combining anti-inflammation and analgesia to prevent peripheral sensitization of nerve.

METHODS

Using clinical practice data from a cohort study at our research center, we established a multivariate logistic regression model to investigate potential risk factors for poor control of zoster-associated pain (ZAP) treated with drugs plus nerve block therapy, including demographic characteristics, complications, laboratory tests, and characteristics of HZ attacks.

RESULTS

Of the 429 patients with ZAP who received drugs plus nerve block therapy, 95 (22.14%) had poor pain control after treatment. The risk of poor pain control was closely related to presence of cancer (odds ratio (OR) 4.173, 95% confidence interval (CI) 1.342-12.970), numerical rating scale score on admission (OR 1.929, 95% CI 1.528-2.434), and red blood cell count (OR 0.560, 95% CI 0.328-0.954). Area under the receiver operator characteristic curve was 0.730. Goodness of fit (Hosmer-Lemeshow) was 0.874.

CONCLUSIONS

The risk of poor pain control in patients with ZAP increased as a result of certain patient characteristics and complications, especially severe pain before treatment and cancer.

Herpes Zoster Duplex Bilateralis After Trauma Induced Emotional Dysregulation: A Case Report and Literature Review

Herpes zoster (HZ) is usually distributed on one side of the body; HZ duplex bilateralis is very rare with only 0.1% of all HZ cases. The occurrence of HZ duplex bilateralis is associated with abnormal immune function. In this report, we present a case of a 47-year-old woman who had no major health issues developed HZ duplex bilateralis after an adverse life event and extreme depression one month ago. HZ related symptoms were controlled after patient received antiviral, analgesic, and nerve-nourishing treatment in our hospital.

A Bilateral Lumbar Multidermatomal Herpes Zoster in an Elderly Woman with Chronic Kidney Disease

Herpes zoster (HZ) is a painful rash caused by the reactivation of the varicella-zoster virus (VZV) permanently latent within the cranial or dorsal root ganglia. Usually the rash presents in only one side of the body, in a single dermatome or restricted to a part of it. In immunocompromised patients, more than one contiguous unilateral dermatome, called multidermatomal HZ, has been described, usually in cervical dermatomes. Bilateral rash is rare. Besides immunosuppression, the major risk factors for virus reactivation are older age and female gender. This is a case of a bilateral lumbar multidermatomal HZ in an elderly woman with chronic renal failure.
