Design outcomes

Primary

MeasureTime frame
Expected outcome 1: Frequency of cases of neuropathic pain among patients with neuritis treated with oral prednisone and amitriptyline for 6 months compared to the group that received oral prednisone and placebo.

Secondary

MeasureTime frame
Expected outcome 2: Result of clinical evaluation (signs / symptoms compatible with neural pain) and the DN4 questionnaire when applied; To evaluate the relationship between the impairment of pain inhibitory pathway measured by Thermal Sensitivity Analysis (TQS) and the result of DN prophylaxis.;Expected outcome 3: Assess the association between neuritis and neuropathic pain findings, assessed by USG, the therapeutic response to amitriptyline; Evaluate the morphology of the affected nerve (s) by ultrasound imaging (USG);;Expected outcome 4: Check whether patients with elevated serum cytokines have a worse response to treatment with amitriptyline; Analyze the inflammatory response in patients with neuritis in order to prove that the cases identified as more susceptible to neuritis due to elevated TNF alpha and neuropathic pain due to increased IL-1? and IL-17 did not present this complication with the use of amitriptyline;;Expected outcome 5: Assess the presence of adverse events associated with the concomitant use of amitriptyline and corticosteroids;;Expected outcome 6: Clinical complications, such as drowsiness and dryness of the mouth.
