Central sensitization and its relationship with health profile in Behçet’s disease

Abstract

Objectives

In this study, we aimed to evaluate the level of central sensitization (CS) and its relationship with health profile, including neuropathic pain and sleep quality in Behçet’s disease (BD).

Method

Eighty-eight patients with BD and 60 healthy controls (HCs) were included in the study between May 2018 and February 2019. Nottingham health profile (NHP), pain DETECT, Pittsburgh sleep quality index (PSQI) questionnaires and the central sensitization inventory (CSI) were administered to all participants. To evaluate the correlations of the NHP, PSQI, and PDQ scores with the CSI score, the CSI was modified for each questionnaire. The activity of BD was determined by the Behçet’s disease current activity form (BDCAF).

Results

CSI scores were significantly higher in patients with BD than HCs (BD: 41.2 ± 21.1 vs HCs: 20.4 ± 16.9, p < .001). Clinical CS was detected in 69.3% of patients with BD and 28.3% of HCs (p < .001). Severe or extreme CS (CSI score ≥ 50) was present in 37.5% of patients with BD and 5.0% of HCs (p < .001). There were high correlations between the modified CSI scores and the NHP, PDQ and PSQI scores in patients with BD (R = 0.804; p < .001, Rho = 0.698; p < .001, and Rho = 0.734; p < .001, respectively). There was significant correlation between CSI and BDCAF scores (Rho= 0.470, p < .001).

Conclusion

CS is more frequent and more severe in patients with BD than in HCs. There is a strong correlation between the severity of CS and poor health profile in patients with BD.
