Randomized Controlled Trial Comparative StudySensory and Thermal Quantitative Testing in Children With Sickle Cell Disease.
Very little is known about pain processing in sickle cell disease (SCD). We examined the mechanical and thermal sensory patterns in children with SCD. Children ages 10 to 17 years (n = 48; mean 13.7 ± 2.0 y; 22 females) participated in quantitative sensory testing (QST) procedures and completed a quality of life (PedsQL) and anxiety and depression scale (RCADS). ⋯ Clinicians need to be aware that sickle cell pain may not only be inflammatory or ischemic secondary to vasoocclusion and hypoxia, but may also be neuropathic secondary to nerve injury or nerve dysfunction. Neuropathic pain in SCD may be the result of tissue damage after vaso-occlusion in neural tissues, whether peripherally or centrally. Future studies are needed to determine the presence of neuropathic pain in children with SCD.
