IntroductionDue to the aging population worldwide, chronic pain is becoming an important public health concern. Chronic pain is bidirectional associated with psychiatric disorders including depression and anxiety. Antidepressants are widely used as adjuvant therapy for the treatment of chronic pain for many disorders.Objectives and aimsTo review available literature on the efficacy and safety of antidepressants for the treatment of chronic pain, including neuropathic pain, fibromyalgia, low back pain, and chronic headache or migraine.MethodsWe performed a detailed literature review through PubMed, EMBASE and Cochrane's Library to assess the efficacy and safety of antidepressants in chronic pain conditions.ResultsIn neuropathic pain, fibromyalgia, low back pain, and chronic headaches/migraine, tricyclic antidepressants (TCAs) showed a significant analgesic effect. Selective serotonin reuptake inhibitors (SSRIs) are not effective for the treatment of low back pain and headaches or migraine. Venlafaxine, a serotonin norepinephrine reuptake inhibitor (SNRI) showed significant improvement of fibromyalgia and neuropathic pain. Duloxetine (SNRI) also reduced the pain in fibromyalgia.ConclusionTCAs are the ‘gold standard’ antidepressant analgesics. However, an electrocardiogram and postural blood pressure should be implemented prior to TCA treatment and TCAs should be initiated at low dosages and subsequently increased to the maximum tolerated dose. One should pay attention to their cardiotoxic potential, especially in the older population. For the treatment of neuropathic pain, SNRIs are second-line agents. Although better tolerated, in most types of chronic pain conditions, the effectiveness of SSRIs is limited. To conclude: start low, go slow, and prescribe with caution.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Chronic Pain Conditions

Fibromyalgia (FM) and chronic low back pain (CLBP) have shared pathophysiology and have a considerable impact on patients’ daily activities and quality of life. The main objective of this study was to compare pain impact, somatosensory sensitivity, motor functionality, and balance among 60 patients with FM, 60 patients with CLBP, and 60 pain-free controls aged between 30 and 65 years. It is essential to know the possible differences existing in symptomatology of two of the major chronic pain processes that most affect the population, such as FM and CLBP. The fact of establishing possible differences in sensory thresholds, motor function, and proprioceptive measures among patients with FM and CLBP could bring us closer to a greater knowledge of the chronic pain process. Through an observational study, a comparison was made between the three groups (FM, CLBP, and pain-free controls) evaluating functional performance, postural balance, kinematic gait parameters, strength, depression, fatigue, and sensitivity to pain and vibration. Patients with chronic pain showed worse somatosensory sensitivity (p < 0.001) and motor function (p < 0.001) than pain-free controls. Moreover, patients with FM showed greater pain impact (p < 0.001) and bigger somatosensory (p < 0.001) and motor deficiencies (p < 0.001) than patients with CLBP. Further research should explore the possible reasons for the greater deterioration in patients with FM in comparison with other chronic pain conditions. Our results, showing the multiple areas susceptible of deterioration, make it necessary to adopt interdisciplinary interventions focused both on physical and emotional dysfunction.

76 patients with chronic low back pain were asked to complete the Pain Disability Index and a family history pain checklist. A significant positive relationship was found between severity of chronic pain disability and the number of chronic pain conditions in the patients' families of origin and genesis. These findings support the position that pain disability is learned from family members, but controlled research is needed before dismissing the possible role of genetic and other factors.

Insight Into

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.

Background and Objectives: Musculoskeletal dysfunction can induce several types of chronic pain syndromes. It is of particular interest to elucidate the pathomechanism of different forms of chronic pain. It is possible that patients who have developed chronic widespread pain (CWP) may endure different pathomechanisms as compared to those who suffer from local pain (osteoarthritis, OA) and regional pain (chronic low back pain, cLBP), especially with regard to pain regulation and its related biomediators. The aim of this study was to determine the differences in pathomechanisms among these patients by measuring pain-related biomediators, particularly brain-derived neurotrophic factor (BDNF). Additionally, subpopulations of immune cells were determined in parallel. Materials and Methods: Patients and healthy subjects (HSs) were recruited (age and gender-matched). BDNF was measured from serum samples of patients and HSs and the data of body composition parameters were recorded. Additionally, both patients and HSs were asked to fill in questionnaires related to pain intensity, anxiety, and depression. Results: Our results highlight that the levels of both free and total BDNF are significantly lower in pain patients compared to HSs, with p values of 0.041 and 0.024, respectively. The number of CD3− CD56bright natural killer (NK) cells shows significant differences between the groups. Comparing all chronic pain patients with HSs reveals a significantly lower number of CD4+ CD8+ T cells (p = 0.031), CD3− CD56bright NK cells (p = 0.049) and CD20+ CD3− cells (p = 0.007). Conclusions: To conclude, it seems that a general conformity between the pathomechanisms of different chronic pain diseases exists, although there are unique findings only in specific chronic pain patients.

Abstract Objectives Better indicators from affordable, sustainable data sources are needed to monitor population burden of musculoskeletal conditions. We propose five indicators of musculoskeletal health and assessed if routinely available primary care electronic health records (EHR) can estimate population levels in musculoskeletal consulters. Methods We collected validated patient-reported measures of pain experience, function and health status through a local survey of adults (≥35 years) presenting to English general practices over 12 months for low back pain, shoulder pain, osteoarthritis and other regional musculoskeletal disorders. Using EHR data we derived and validated models for estimating population levels of five self-reported indicators: prevalence of high impact chronic pain, overall musculoskeletal health (based on Musculoskeletal Health Questionnaire), quality of life (based on EuroQoL health utility measure), and prevalence of moderate-to-severe low back pain and moderate-to-severe shoulder pain. We applied models to a national EHR database (Clinical Practice Research Datalink) to obtain national estimates of each indicator for three successive years. Results The optimal models included recorded demographics, deprivation, consultation frequency, analgesic and antidepressant prescriptions, and multimorbidity. Applying models to national EHR, we estimated that 31.9% of adults (≥35 years) presenting with non-inflammatory musculoskeletal disorders in England in 2016/17 experienced high impact chronic pain. Estimated population health levels were worse in women, older aged and those in the most deprived neighbourhoods, and changed little over 3 years. Conclusion National and subnational estimates for a range of subjective indicators of non-inflammatory musculoskeletal health conditions can be obtained using information from routine electronic health records.

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
