Abstract
PURPOSE: To examine the association between catastrophizing and pain intensity with acute herpes zoster, and the association of treatment-related early changes in depressive symptoms, anxiety, and catastrophizing with postherpetic neuralgia (PHN) development, independent of acute pain intensity. METHODS: We analyzed 44 outpatient participants with acute herpes zoster who completed a 6-month follow-up. Participants completed a self-reported questionnaire with a Visual Analog Scale (VAS), the Pain Catastrophizing Scale (PCS), and the Hospital Anxiety and Depression Scale (HADS) at first visit, and 3 and 6 months, thereafter. We assessed associations between acute pain intensity and analyzed factors using univariate regression analyses. Univariate and bivariate logistic regression models were constructed to assess associations of variables at the first visit and early changes in psychological factors with PHN development. RESULTS: Sex, severe skin rash at first visit, PCS, and HADS depression were associated with acute pain intensity {standardized regression coefficient, 0.46 [95% confidence interval (CI) 0.12-0.74], 0.36 (95% CI 0.07-0.65), 0.33 (95% CI 0.03-0.62), 0.47 (95% CI 0.19-0.74), respectively}. Acute pain intensity and early change in pain intensity were associated with PHN development [odds ratio (OR) 1.08 (95% CI 1.02-1.14) OR 2.38 (95% CI 1.10-5.16), respectively]. Decreased PCS was associated with decreased risk of PHN development, independent of acute pain intensity [OR 0.31 (95% CI: 0.12-0.80)]. CONCLUSION: Catastrophizing was associated with acute pain intensity, and lower pain-related catastrophizing among patients with acute herpes zoster was associated with less risk of PHN development, independent of acute pain intensity.
