Plain English summary of protocol

Background and study aims
Sciatica refers to back pain caused by a problem with the sciatic nerve. This is a large nerve that runs from the lower back down the back of each leg. When something injures or puts pressure on the sciatic nerve, it can cause pain in the lower back that spreads to the hip, buttocks, and leg.
The objective of the present study will be to compare the effectiveness of the medications of the systemic corticosteroids class in relation to lumbar infiltrations in the relief of sciatica caused by lumbar disc herniation.

Who can participate?
Patients with severe sciatica, with recent onset, being followed up at the Spine Surgery outpatient clinic at Hospital São Paulo and Hospital Municipal de Barueri

What does the study involve?
Patients will be drawn in two groups in relation to the treatment they will be submitted for pain relief and resumption of function. It is important to highlight that both treatments are routinely performed in this clinic and participation in the study does not increase the risk of therapy failure in resolving the clinical condition. In the first approach, an initial interview will be carried out and protocols filled out that seek to measure the intensity of the pain that the patient presents, as well as pertinent imaging exams will be requested if the patient does not have them. After 1 week of the initial care, the intervention will be performed, according to the group for which the patient was drawn. These correspond:
- Group 1: The participants of this group will be submitted to transforaminal epidural infiltration, with corticosteroids and analgesics of local action, performed in a surgical environment under sedation. In summary, the participant will be instructed to be admitted to the hospital on the same day of the procedure, fasting at least 8 hours. In the operating room, the participant will be in prone position (lying on his stomach) and, after medication to sedate and relieve the pain of the procedure, the researcher will perform the procedure, lasting about 20 minutes. After recovery from anesthesia, with about 3 hours, the participant will be discharged from hospital with the appropriate guidelines.
- Group 2: Participants in this group will undergo treatment with oral medications for 3 weeks, these being 20mg prednisone, according to medical prescription.
After treatment, the participant will be reassessed in 3 weeks and 6 weeks after the intervention, in the same outpatient clinic where initial care was performed and, on this occasion, the pain and function forms will be reapplied in order to measure the improvement in pain and function obtained. with each treatment.

What are the possible benefits and risks of participating?
The main benefits of participating in the research include mainly the contribution to optimize the treatment of cases similar to yours, aiming at improving the indication of each one of them in the case of acute sciatica. For the participant, the main benefit is the relief of pain and improvement of the clinical condition and function, since both treatments are effective in resolving symptoms.
Each treatment modality has inherent risks, with low rates of probability of occurrence.

Where is the study run from?
1. Hospital São Paulo (Brazil)
2. Hospital Municipal de Barueri (Brazil)

When is the study starting and how long is it expected to run for?

Scientific titleLumbar transforaminal epidural injection versus systemic corticosteroids for the treatment of acute sciatica: a randomized clinical trial
Study acronymTEISC
Study objectivesOur hypothesis is that systemic administration of oral corticosteroids is equivalent to peri-radicular transforaminal infiltrations in relation to improvement of pain and function in patients with higher intensity acute sciatica (Oswestry index greater than 40). Thus, if proven, the prescription of these medications may constitute a less invasive and more accessible option in the treatment of these patients. On the other hand, if the hypothesis is rejected, the systemic prescription of these medications can be reconsidered in view of the side effects associated with this medication class.
Ethics approval(s)Approved in 14/12/2020, Research Ethis Committee of Federal University of São Paulo (Botucatu St., 740, 5 floor - CEP: 04023-900 - São Paulo-SP, Brazil; +55(11)5571-1062; no email provided), ref: 4.460.808
Health condition(s) or problem(s) studiedTreatment for acute sciatica pain due to lumbar disc herniation
InterventionThis is a prospective randomized clinical trial developed at the Orthopedics-Column outpatient clinic of Hospital São Paulo (EPM / UNIFESP) and its affiliated Hospital Municipal de Barueri.
Individuals with a clinical condition compatible with acute sciatica secondary to lumbar disc herniation are randomly allocated into 2 groups regarding the treatment of choice. The randomization is realized in the randomization module of RedCap database.
- Group 1: the participants of this group will be submitted to transforaminal lumbar epidural infiltration in the week following the initial care. Transforaminal epidural infiltrations are performed using aseptic technique in the operating room. After confirmation of the appropriate location in the foramen through fluoroscopy, 1 ml of iodinated contrast is injected to identify the emerging root. If the desired image is visualized, a solution containing 2.5 ml of analgesics with local action and 2.5 ml of particulate corticosteroids will be administered.
- Group 2: participants in this group will be treated with oral prednisone starting in the week following the initial treatment. The medication used is prednisone, a synthetic corticosteroid with low mineralocortocoid activity. The total dose accumulated in the treatment cycle is 650mg, capable of promoting anti-inflammatory effects without immunosuppression. In addition, this dose has a low risk of suppression of the hypothalamic-adrenal axis, considering that the total treatment time will not exceed 3 weeks.
Intervention typeProcedure/Surgery
Primary outcome measureOswestry Disability Index measured at baseline, 21 days and 60 days.
Secondary outcome measures1. Pain measured using visual analogue scale at baseline, 21 days and 60 days
2. Presence of neurological deficits - measurement of muscle strength (Global Strength Index, recommended by the Medical Research Council) and tactile sensitivity test compared to the contralateral side (as recommended in the sensitivity measurement protocols) at baseline, 21 days and 60 days

At the end of the research and publication of the results, the participants will have information about the data obtained and, consequently, their contribution to the improvement of the treatment of acute sciatica secondary to lumbar disc herniation .
IPD sharing planThe datasets generated during and/or analysed during the current study will be stored in a non-publically available repository (redcap.epm.br) and will be available upon request for the authors. All the procedures and sociodemographic, clinical and procedures will be available for researchers who provide a methodologically sound proposal. The participant identification data are available only for the main author. In the initial interview, all the participants will be oriented about the sharing of his data and the agreement will be registered by the ICF. The dataset also will be publically available in the subsequent results publication.
