Background:Common low back pain (LBP) is a common health problem affecting 50 to 80% of working age adults. It is one of the common and costly health problems in Tunisia. Actually, the role of the immune response and inflammatory cytokines in the pathogenesis of chronic pain has been of growing interest.Objectives:The aim of this study was to assess whether pro and anti-inflammatory cytokines could be detected in serum in patients with LBP compared with healthy subjects and whether they could be related to pain severity and to clinical findings.Methods:It was a an analytical cross-sectional study including 50 patients with at least three months of LBP, in the department of rheumatology, orthopedics and immunology at the Military Hospital of Tunis between January 1st and March 31, 2020. All patients had a standardized clinical assessment.Levels of serum cytokines IL-6, IL-8, IL-1β and TNF- α, were measured using the chimiluminescence technique. Serum concentration of IL-10 was assayed by the enzyme-linked immunosorbent assay technique (ELISA). The normal levels of cytokines were determined in 50 healthy controls.Results:The mean age of the patients was 41.9 ± 8.4 years and the sex ratio was 4.5. LBP duration was 66.4 months. The mean lumbar visual analog scale (VAS) was 4.5 ± 1.9, and the root VAS was 2.6 ± 2.5. Neuropathic pain was found in 26% of patients. The average BMI was 27 ± 3.7 kg/m2. Only serum level of IL-8 was significantly higher in subjects with LBP compared to healthy controls (p <10-3). IL-1β was indetectable in both patients and controls. Positive correlations were found between IL-8 levels and anxiety/functional scores (r = 0.3; p = 0.02/ r = 0.3; p = 0.04). IL-6 was positively correlated with BMI, and negatively correlated with the Schober test. No correlations were found between serum levels of IL-6, IL-8, IL-10, TNF-α and pain intensity (VAS), neuropathic pain (DN4), fibromyalgia (FIRST), depression (HAD) and various radiological data.Conclusion:Interleukin-8 is a biomarker of common low back pain and correlate with anxiety and functional disability. These results suggest that IL-8 may be a therapeutic target to reduce chronic back pain and reduce the social and profession impact.Disclosure of Interests:None declared

Background: Activation of the sympathetic nervous system attenuates inflammation via catecholamines. Recent evidence has shown that electroacupuncture (EA) activates neuronal networks involved in the release of dopamine and norepinephrine that control systemic inflammation. In muscle, catecholamines are related to cyclic adenosine monophosphate (cAMP). This signaling molecule has been implicated in recovery from sustained contractile activity, which may induce muscular pain, such as that which occurs during low back pain (LBP). Objective: Our aim was to evaluate the effects of EA used for the control of LBP on the activation of the sympathetic nervous system in a randomized controlled clinical trial in athletes. Methods: Two groups of athletes with acute or chronic low back pain were studied. EA, sham EA and pharmacological treatment (diclofenac sodium) were evaluated. The outcome measures included a pain score represented by a visual analogue scale (VAS) and serum levels of catecholamines quantified by enzyme-linked immunosorbent assay. In addition, blood was collected into chilled heparin tubes, placed in 96-well cell culture plates and incubated with an equal volume of Roswell Park Memorial Institute (RPMI) medium, with lipopolysaccharide (LPS) alone or with catecholamines. Tumor necrosis factor (TNF)-α levels in the supernatants were analyzed. Results: The results indicated that the initial pain ratings did not differ between the groups analyzed. EA induced epinephrine secretion but not norepinephrine or dopamine secretion. Although EA and pharmacological treatment did not differ in terms of pain relief, in vitro epinephrine and norepinephrine reduced TNF-α production in response to LPS stimuli. Conclusion: EA activates the sympathetic nervous system and induces the release of epinephrine, which could ameliorate inflammation and protect muscular tissue in addition to relieving pain.

The cognitive–evaluative (C–E) dimension of pain is commonly observed in patients with a relatively long duration of pain. However, little is known about the effects of pain relapse on the C–E dimension of pain. Moreover, the improvement process of the C–E dimension of pain following treatment is unknown. The objective of this case report was to (a) demonstrate that the C–E dimension was affected in the acute phase of neuropathic pain in cases of pain relapse, and (b) demonstrate the improvement process of the C–E dimension of pain. A woman was diagnosed with low back pain (LBP) and sciatica. The patient had previously experienced symptoms of LBP and sciatica; thus, this episode was a case of pain relapse. At the beginning of rehabilitation, the C–E dimension of pain was present in addition to the sensory–discriminative (S–D) dimension of pain. It was observed that improvement of the C–E dimension of pain was delayed in comparison with that of the S–D dimension of pain. The C–E dimension of pain was observed with pain relapse even though it was in the acute phase of pain. This case provides a novel insight into the C–E dimension of pain. Moreover, the delay in improving the C–E dimension of pain indicates a difference in the improvement process for each pain dimension.

Abstract Background Low back pain (LBP) is one of the most common musculoskeletal disorders, causing significant personal and social burden. Current research is focused on the processes of the central nervous system (particularly the sensorimotor system) and body perception, with a view to developing new and more efficient ways to treat chronic low back pain (CLBP). Several clinical tests have been suggested that might have the ability to detect alterations in the sensorimotor system. These include back-photo assessment (BPA), two-point discrimination (TPD), and the movement control tests (MCT). The aim of this study was to determine whether the simple clinical tests of BPA, TPD or MCT are able to discriminate between nonspecific CLBP subjects with altered body perception and healthy controls. Methods A cross-sectional study was conducted. At one point in time, 30 subjects with CLBP and 30 healthy controls were investigated through using BPA, TPD and MCT on the lower back. Correlations among the main covariates and odds ratios for group differences were calculated. Results MCT showed an odds ratio for the presence of CLBP of 1.92, with a statistically significant p-value (0.049) and 95%CI. The TPD and BPA tests were unable to determine significant differences between the groups. Conclusions Of the three tests investigated, MCT was found to be the only suitable assessment to discriminate between nonspecific CLBP subjects and healthy controls. The MCT can be recommended as a simple clinical tool to detect alterations in the sensorimotor system of nonspecific CLBP subjects. This could facilitate the development of tailored management strategies for this challenging LBP subgroup. However, further research is necessary to elucidate the potential of all the tests to detect alterations in the sensorimotor system of CLBP subjects. Trial registration No trial registration was needed as the study contains no intervention. The study was approved by the Swiss Ethics Commission of Northwest and Central Switzerland (EKNZ) reference number 2015–243.

Abstract Urinary excretion of hydroxyproline was measured in 12 cases of multiple fractures as an index of bone collagen metabolism. Measurements were made for 10 consecutive days after injury; 10 patients with low back pain served as the control group. With three exceptions, the mean daily excretion of hydroxyproline and the day-to-day variations were within the same range in the group with multiple fractures as in the control group.

Abstract Aim. To evaluate ultrasonography findings of Thoracolumbar Fascia (TLF) enthesis in patients with low back pain (LBP) due to iliac crest pain syndrome (ICPS). Method. The ultrasonographic and clinical findings of 60 patients with LBP due to ICPS were compared to those of 30 healthy volunteers with no LBP. Thickness of the TLF was measured with ultrasound (US) at its insertion on the iliac crest. Results. Forty-eight women and 12 men with a mean age of 42.1±11.3 years were diagnosed with ICPS. In patients, the mean thickness of the TLF was 2.51±0.70mm in affected sides compared to 1.81±0.44mm in the contralateral unaffected sides. The mean thickness difference of 0.82mm between the affected and non-affected sides was statistically significant (95%CI, 0.64-0.99, P<0.0001). In volunteers, the mean thickness of the TLF was 1.6±0.2mm. The mean thickness difference of 0.89mm between the affected sides of patients and volunteers was statistically significant (95%CI, 0.73-1.06, P<0.0001). Forty-two patients who didn’t improve with conservative therapy, received injections of methylprednisolone acetate and 1% lidocaine around the TLF enthesis. All patients reported complete relief of their LBP within 20 minutes of the injections thanks to the lidocaine anesthetic effect. Fifty-six (93.3%) patients were reached by phone for a long-term follow-up. Among them, 33 (58.9%) patients experienced a sustained complete pain relief after a mean follow-up of 45±19.3 months (range, 3-74 months). Conclusion. our findings suggest that TLF enthesopathy is a potential cause of nonspecific LBP that can be diagnosed using US.

Objective. Detection of a lateral shift (LS) in patients with diagnosed disc herniation compared to healthy controls. Summary of Background Data. A specific lateral shift (LS) pattern is observed in patients with disc herniation and low back pain, as shown in earlier studies. Methods. Rasterstereography (RS) was used to investigate the LS. Thirty-nine patients with lumbar disc herniation diagnosed by radiological assessment and low back pain and/or leg pain (mean age 48.2 years, mean BMI 28.5, 28 males and 11 females) and 36 healthy controls (mean age 47.4 years, mean BMI 25.7, 25 males and 11 females) were analysed. LS, pelvic tilt, pelvic inclination, lordotic angle, and trunk torsion were assessed. Results. The patient group showed a nonsignificant increase in LS, that is, 5.6 mm compared to the healthy controls with 5.0 mm (p = 0.693). However, significant differences were found between groups regarding pelvic tilt in degrees (patients 5.9°, healthy controls 2.0°; p = 0.016), trunk torsion (patients 7.5°, controls 4.5°; p = 0.017), and lordotic angle (patients 27.5°, healthy controls 32.7°; p = 0.022). The correlation between pain intensity and the FFbH-R amounted 0.804 (p = < 0.01), and that between pain intensity and the pain disability index was 0.785 (p < 0.01). Discussion. Although some studies have illustrated LS with disc herniation and low back pain, the present findings demonstrate no significant increase in LS in the patient group compared to healthy controls. Conclusion. The patients with lumbar disc herniation did not demonstrate an increased LS compared to healthy controls. Other parameters like pelvic tilt and inclination seemed to be more suitable to identify changes in posture measured by RS in patients with low back pain or disc herniation.

BackgroundThe evidence that exercise intervention is effective for treatment of chronic low back pain comes from trials that are not placebo-controlled.ObjectiveThe purpose of this study was to investigate the efficacy of motor control exercise for people with chronic low back pain.DesignThis was a randomized, placebo-controlled trial.SettingThe study was conducted in an outpatient physical therapy department in Australia.PatientsThe participants were 154 patients with chronic low back pain of more than 12 weeks’ duration.InterventionTwelve sessions of motor control exercise (ie, exercises designed to improve function of specific muscles of the low back region and the control of posture and movement) or placebo (ie, detuned ultrasound therapy and detuned short-wave therapy) were conducted over 8 weeks.MeasurementsPrimary outcomes were pain intensity, activity (measured by the Patient-Specific Functional Scale), and patient's global impression of recovery measured at 2 months. Secondary outcomes were pain; activity (measured by the Patient-Specific Functional Scale); patient's global impression of recovery measured at 6 and 12 months; activity limitation (measured by the Roland-Morris Disability Questionnaire) at 2, 6, and 12 months; and risk of persistent or recurrent pain at 12 months.ResultsThe exercise intervention improved activity and patient's global impression of recovery but did not clearly reduce pain at 2 months. The mean effect of exercise on activity (measured by the Patient-Specific Functional Scale) was 1.1 points (95% confidence interval [CI]=0.3 to 1.8), the mean effect on global impression of recovery was 1.5 points (95% CI=0.4 to 2.5), and the mean effect on pain was 0.9 points (95% CI=−0.01 to 1.8), all measured on 11-point scales. Secondary outcomes also favored motor control exercise.LimitationClinicians could not be blinded to the intervention they provided.ConclusionsMotor control exercise produced short-term improvements in global impression of recovery and activity, but not pain, for people with chronic low back pain. Most of the effects observed in the short term were maintained at the 6- and 12-month follow-ups.
