Hematological Indices and Sympathetic Block Response in Neuropathic Pain (HINSPAIN)
Hematological Inflammatory Indices as Predictors of Treatment Response to Sympathetic Nerve Blocks in Neuropathic Pain: A Prospective Observational Study
Aperçu de l'étude
Statut
Description détaillée
Neuropathic pain is a complex chronic pain condition involving inflammatory, neural, and immune-mediated mechanisms. Increasing evidence suggests that systemic inflammatory processes may contribute to the pathophysiology and persistence of neuropathic pain. Hematological inflammatory indices derived from routine complete blood count parameters have recently emerged as inexpensive and accessible biomarkers reflecting systemic inflammatory status.
Although several studies have investigated inflammatory markers in chronic pain syndromes, data regarding the relationship between hematological inflammatory indices and treatment response following sympathetic nerve block interventions in neuropathic pain are limited.
This prospective observational study aims to evaluate whether hematological inflammatory indices are associated with treatment outcomes in neuropathic pain patients treated with sympathetic nerve block procedures as part of routine clinical management. Adult patients diagnosed with neuropathic pain and scheduled for sympathetic nerve block treatment will be prospectively followed for 3 months.
Clinical outcomes including Numeric Rating Scale (NRS), DN4 and/or LANSS neuropathic pain scores, Global Perceived Effect (GPE), and analgesic consumption will be recorded. Hematological indices including NLR, PLR, MLR, SII, SIRI, AISI, and RDW will be calculated using routine hemogram parameters.
The study is designed as a non-interventional, single-center, prospective observational clinical study. The treatment approach will not be altered for research purposes.
