PSYCHO-EMOTIONAL ASPECTS IN THE FORMATION OF PAIN SYNDROME CHARACTERISTICS IN PATIENTS WITH MULTIPLE SCLEROSIS

Introduction: Pain syndromes, anxiety, and depression are common syndromes in multiple sclerosis (MS). Comorbidity of pain and depression or pain and anxiety exists in up to one-third of MS patients. Based on the biopsychosocial model of pain, given the high prevalence of these symptoms and their frequent combination in MS, which is significantly higher than in the general population, we can hypothesize the relationship between the characteristics of pain and anxiety and depression in patients with MS. Objectives: To assess the prevalence of anxiety and depression among MS patients with pain syndromes and analyze the relationship between anxiety and depression with pain syndromes' characteristics in patients with MS. Methods: Data were collected prospectively at Lviv Regional Multiple Sclerosis Center. 120 randomly selected patients with a confirmed diagnosis of multiple sclerosis were examined. 104 of them had pain syndromes during the last month. Complaints and medical history, analysis of medical records, neurological and general medical examination of the patients were collected. Depressive symptoms and anxiety were assessed in all patients using the Hospital Anxiety and Depression Scale (HADS) questionnaire. In patients with pain syndromes, the Visual analogue scale (VAS), Short-form McGill Pain Questionnaire 2 (SF-MPQ-2), Pain Detect were used to assess pain characteristics. Results: The levels of anxiety and depression were higher in the group of MS patients with pain. The level of anxiety was 9.0 [6,0; 12,75] in the group with pain and 7.0 [4,0; 9,25] in the group without pain (p=0.04). The level of depression was 7.0 [4,0; 10,0] in the group with pain and 4.0 [1,75; 6,0] in the group without pain (p<0,01). It was found that part of MS patients with pain syndromes with anxiety was 36.5%, and 29.8% had a subclinical level of anxiety; part of MS patients with pain syndromes with depression was 19.23%. The proportion of patients with anxiety was highest in patients with neuropathic pain: 56.3% ± 8.8% vs. 22.4% ± 6.0% with nociceptive, p<0.01. A similar situation is observed in patients with depression. The share of patients with depression was higher in the group with neuropathic pain 37.5% ± 8.6%, compared to 14.3% ± 5.0% with nociceptive, p=0.02. The proportion of patients with MS without signs of anxiety and depression is significantly higher among patients with nociceptive pain (p<0,05). Also, the correlational relationship between the level of anxiety and depression with the level of the neuropathic type of pain manifestation was found (r=0,40; p<0,01 and r=0,30; p<0,01). Levels of anxiety and depression correlated with the average pain intensity per month (r = 0,21; p=0,03) and did not have a statistically significant relationship with pain intensity at the time of examination and the strongest pain for the last month. The anxiety and depression had correlations with all components of the structure of pain syndromes (according to sfMPQ-2), but the most pronounced direct correlation was found between anxiety and the affective component of pain (r=0,57; p<0,01). It was also found that the level of anxiety was proved to be higher in patients who have 2-3 pain syndromes, than in patients with one pain syndrome: 12.0 [8,0; 14,0] points against 8.0 [5,0; 11,0] points, p<0.01. Besides, this localization of pain in the arms, shoulders and back was related to higher levels of anxiety (r=0.22; p=0.03). Conclusion: Pain syndromes, anxiety, and depression are widespread among patients with MS and there is a relationship between them. MS patients with pain have higher levels of anxiety and depression than MS patients without pain. It is also noteworthy that among MS patients with pain syndromes, high levels of anxiety are detected. Anxiety and depression also have a pronounced relationship with a neuropathic component of pain in patients with MS. Besides this, the presence of more than one pain syndrome, high average pain intensity per month is associated with higher levels of anxiety and depression. The localization of pain in the arms, shoulders and back is related to higher anxiety levels. These discoveries, combined with modern neuroimaging technologies used in the next step of our study, will provide a better understanding of both pain and its structure, as well as anxiety and depression

Introduction: Leriche syndrome is an aortoiliac occlusive disease caused by atherosclerotic occlusion. We report a case of Leriche syndrome with a fracture that was suspected as complex regional pain syndrome (CRPS), as the post-traumatic pain gradually worsened in the form of excruciating neuropathic pain. Case Report: A 52-year-old woman with a history of hypertension was referred to the Department of Pain Medicine from a local orthopedic clinic because of suspected CRPS for excruciating neuropathic pain for one month. She complained of gait dysfunction and severe pain in the right foot following an incident of trauma with the right first toe. The average pain intensity assessed using the visual analog scale (VAS) was 90 (0: no pain, 100: the worst pain imaginable), and the neuropathic pain was evident as a score of 6/10 on Douleur neuropathique 4. Allodynia, hyperalgesia, blue discoloration of the skin, asymmetric temperature change (1.38 °C), and edematous soft tissue changes were observed. Ultrasonography showed a chip fracture in the first distal phalanx of the right first toe. The diagnosis was most probably CRPS type I according to the Budapest research criteria for CRPS. However, multiple pain management techniques were insufficient in controlling the symptoms. A month and a half later, an ankle-brachial index score of less than 0.4 suggested severe peripheral artery disease. Computed tomography angiography showed total occlusion between the infrarenal abdominal aorta and the bilateral common iliac arteries. Therefore, she underwent aortic-bifemoral bypass surgery with a diagnosis of Leriche syndrome. Three months after the surgery, the average pain intensity was graded as 10 on the VAS (0–100), the color of the skin of the right first toe improved and no gait dysfunction was observed. Conclusion: A chip fracture in a region with insufficient blood flow could manifest as excruciating neuropathic pain in Leriche syndrome.

Aim of the research is to analyze the patterns of pain syndromes and their characteristics in multiple sclerosis patients. Materials and Methods. A total of 104 multiple sclerosis patients complaining of pain during the last month were examined in Lviv Regional Multiple Sclerosis Center. We analyzed medical records, performed general medical and neurological examinations and compiled history of lifestyle, illness and pain. The VAS and PainDetect questionnaires were used to assess the characteristics of pain syndromes. The patients were asked to choose one of the 4 typical patterns of pain, which best described their feelings. Then the analysis of pain syndrome patterns and their characteristics was carried out. Results and Discussions. All 4 typical patterns of pain syndromes were registered in multiple sclerosis patients. However, only 26.92% of the participants experienced an intermittent pain pattern. The rest of patients suffered from patterns characterized by persistent pain. The evaluation of the patterns and their characteristics revealed typical features. The highest intensity of the severest and average pain during the last month was present in the patients suffering from constant pain with distinct attacks: 8.0 [7.0; 9.0] points (p<0.05) and 7.0 [5.0; 8.0] points (p<0.05), respectively. Persistent paroxysmal pain was more common in the multiple sclerosis patients with neuropathic pain (43.8±8.8% vs 20.4±5.8%, p<0.05). Irradiating pain is also characteristic to this pattern in 52.9±8.6% of patients (p<0.05). The head is the most common pain localization in the patients experiencing persistent pain with severe attacks - 82.4±9.2% of cases (p<0.05). Conclusions. Pain is a permanent symptom in a significant number of multiple sclerosis patients. It can have different patterns of progression. However, it has typical characteristics and their understanding will aid in the diagnosis, prognosis and treatment of pain syndromes in multiple sclerosis patients

Abstract Background: Pain in sickle cell disease (SCD) has been thought to be episodic, but more recent evidence has shown that individuals in this population also suffer from chronic pain likely resulting from central or peripheral neural damage (neuropathic pain). There is accumulating evidence from human and animal studies indicating potential neuropathic pain in SCD. A number of valid and reliable measures of neuropathic pain have been used to differentiate neuropathic from non-neuropathic types of pain. PAINReportIt, which takes about 10 to 18 minutes to complete, is a computer based self-report pain assessment tool based on the 1970 version of the McGill Pain Questionnaire. From PAINReportIt, a new subscale has been proposed as a measure of neuropathic pain that sums the number of neuropathic pain quality words selected. The PAINReportIt number of neuropathic pain (PR-NNP) scale, however, lacks validation in patients with SCD. Aim: The purpose of this study was to determine the construct validity for the PR-NNP by examining the associations between the PR-NNP and other valid and reliable measures of neuropathic pain (self-administered Leeds Assessment of Neuropathic Symptoms and Signs [S-LANSS] and the Neuropathic Pain Symptom Inventory [NPSI]) among adults with SCD. We hypothesized that the PR-NNP scores would be significantly correlated with S-LANSS and NPSI scores. Methods: This prospective instrument validation study was conducted in an ambulatory research setting with 79 adults diagnosed with SCD who had chronic pain within the prior 12 months (>3 on a 0-10 pain scale). The sample mean age was 36.0 ± 11.5 [ranged from 19-74 years], 63% were female, and 97% reported they were African American. The participants were asked to complete self-reported pain measures (PR-NNP, S-LANSS, NPSI, and PR-NNoc [number of nociceptive pain words]). Descriptive, correlational, and regression analyses were used. Results: Mean scores for average pain intensity, PR-NNP, NSPI, S-LANSS, and PR-NNoc appear in Table 1. Bivariate results indicated moderate correlation between the two validated measures of neuropathic pain (NPSI and S-LANSS; r= .57, p=.000). The NPSI was moderately correlated with PR-NNP (r= .43, p=.000), and weakly correlated with PR-NNoc (r=.35, p=.002). For S-LANSS, there was a moderate correlation with PR-NNP (r=0.41, p=.000) and a weak correlation with PR-NNoc (r=.30, p=.007). There was a weak correlation between average pain intensity and NPSI and S-LANSS, r=.37, p=.001 and r=.36, p=.001, respectively. Regression analysis including average pain intensity, PR-NNP, and PR-NNoc as predictors showed that controlling for PR-NNP and average pain, PR-NNoc was not significantly associated with either NPSI (p=.930) or S-LANSS (p=.731), while each point of increase in PR-NNP was associated with an increase of 1.9 (p=.004) in NPSI and of 0.8 (p=.003) in S-LANSS. The same analysis showed that a one point increase in the average pain intensity was associated with an increase of 2.7 (p=.001) in NPSI and of 1.0 (p=.001) in S-LANSS. Conclusions: Both average pain intensity and PR-NNP but not PR-NNoc have unique explanatory properties of both indicators of neuropathic pain (NPSI and S-LANSS). These findings support the construct validity of the PR-NNP as a potential screening tool for neuropathic pain in patients with SCD. Validation of PR-NNP is important for future neuropathic pain research in the sickle cell population, particularly in cases of multi-site trials, and in cases where the practitioner can detect the potential presence of neuropathic pain without use of expensive equipment. These findings are important because pain management in the sickle cell population often includes opioids, but easy and early detection of neuropathic pain could result in an opioid sparing pain management approach in this population. Disclosures No relevant conflicts of interest to declare.

The aim of the work. To analyze the influence of intensity and neuropathic component of pain syndrome on the quality of life structure characteristics in patients with multiple sclerosis (MS). Materials and methods. 104 MS patients with different types of MS course and complaints of pain during the last month were examined in the Lviv Regional Multiple Sclerosis Center. The patients were interviewed using standardized questionnaires (Pain Detect, VAS, SF-36) followed by an analysis of the pain characteristics influence on the quality of life. Results. When assessing the influence of the main characteristics of MS course, the relationship between the physical component of quality of life and levels of disability (EDSS) and the total number of relapses was found (r = -0.60, P < 0.01; r = -0.34, P < 0.01, respectively). However, the mental component of quality of life had no significant relationship with the level of disability and the number of relapses. The average pain intensity within a month on the VAS scale was 5.0 [4.0; 7.0]. 24.0 % of patients had low-intensity pain, 54.8 % – moderate, 21.2 % – high. In MS patients with low-intensity pain within a month, 5 of the 11 quality of life indicators were significantly higher, in particular, the overall physical component of quality of life – 38.1 [33.8; 48.5] % in low-intensity pain against 31.8 [28.1; 38.7] %, P = 0.02 – in moderate. In MS patients, the level of both physical (r = -0.25; P = 0.01) and mental (r = -0.21; P = 0.03) component of quality of life decreased with increasing pain intensity. The most notable correlation was observed between intensity of pain and such characteristics of quality of life as energy/fatigue (r = -0.37; P ˂ 0.01) and emotional well-being (r = -0.28; P ˂ 0.01). In 30.8 % of patients, pain was neuropathic, in 47.1 % – nociceptive, in 22.1 % – undetermined. MS patients with the neuropathic type of pain had significantly lower scores, 7 out of 11 indicators of quality of life, largely the mental component, than scores in MS patients with nociceptive type (Р < 0.05). Correlation analysis showed the association between an increase in the manifestation of neuropathic pain component and a decrease in all quality of life characteristics, except in health change. In MS patients with a neuropathic component, in increasing level of its manifestation, the mental component of health decreased clearly (r = -0.36; P ˂ 0.01), namely its social functioning characteristic (r = -0.35; P < 0.01). Conclusions. In MS patients, increasing intensity of pain decreases both physical and mental components of quality of life with the most significant decrease in energy/fatigue and emotional well-being as parts of the mental component of quality of life. The neuropathic component of pain and the level of its manifestation are largely associated with a decrease in the mental component of quality of life as the overall indicator and social functioning as its structural element.

Abstract Objective To investigate efficacy of repeated application of capsaicin 179 mg cutaneous patch in non-responders to the first application. Design Post hoc, as-treated analysis of two prospective trials (STRIDE and PACE) with 52-week follow-up. Blinding Open-label. Setting Multicenter clinical trial. Subjects STRIDE: non-diabetic neuropathic pain; PACE: painful diabetic peripheral neuropathy. Methods Patients were divided according to number of applications needed before ≥30% response on average pain intensity (question 5 of the Brief Pain Inventory [BPI-Q5]). We assessed change from baseline in average pain intensity (BPI-Q5), mean ‘interference with sleep’ score, Patient Global Impression of Change, quality of life (QOL) using EuroQol 5-dimension, and Self-Assessment of Treatment. Results In STRIDE and PACE, respectively, n = 306/313 received capsaicin patch; n = 60/96 had a response after the first application, n = 33/68 after the second, n = 11/43 after the third. Among patients without a ≥ 30% reduction in pain intensity at 3 months, 23.3%/28.1% achieved a ≥ 30% reduction at 6 months, increasing to 33.9%/45.7% at 12 months. Similar results were obtained using a decrease of ≥ 50% as responder definition. Progressive improvements in pain intensity in slower responders reached similar levels as those in early responders at month 12 and were accompanied by improvements in sleep, QOL, and patient satisfaction. Conclusions While some patients with peripheral neuropathic pain experience rapid improvements with a single treatment of capsaicin 179 mg patch, some may require two or three treatments before an initial response is observed. Similar benefits on pain, sleep, and QOL can be achieved in early and late responders.

Introduction: This study examined the prevalence, intensity, interference, and biopsychosocial correlates of pain in a large community-based sample of persons with multiple sclerosis (MS). Methods: Mail surveys were returned by 442 members of the King C ounty (WA) MS Association. Average pain intensity, pain-related activity interference, depressive symptoms and severity of MS were assessed. Results: Forty-four percent reported persistent, bothersome pain in the three months prior to completing the survey. Participants with pain reported an average pain intensity rating of 5.2 (SD =2.3) on the 0 (no pain) to 10 (pain as bad as could be) scale. Twenty-seven percent reported severe pain (score of 7-10), while 51% of those with pain rated the interference of their pain with daily activities as none to minimal. Twenty percent reported severe interference in activities as a result of pain. In multivariate modeling, MS illness severity, marital status, and self-ratings of overall health were significantly associated with pain-related interference with activities. Conclusions: A pproximately a fourth of this sample described having a chronic pain problem characterized by severe pain intensity and significant pain-related interference with activities. Disability due to pain may be more important than previously recognized for the MS population.

Over Time

Postherpetic itch (PHI), or herpes zoster itch, is an intractable and poorly understood disease. We targeted 94 herpes zoster patients to investigate their pain and itch intensities at three separate stages of the condition (acute, subacute, and chronic). We used painDETECT questionnaire (PDQ) scores to investigate the correlation between PHI and neuropathic pain. Seventy-six patients were able to complete follow-up surveys. The prevalence of PHI was 47/76 (62%), 28/76 (37%), and 34/76 (45%) at the acute, subacute, and chronic stages, respectively. PHI manifestation times and patterns varied. We investigated the relationship of PHI with neuropathic pain using the visual analog scale (VAS), which is a measure of pain intensity, and the PDQ, which is a questionnaire used to evaluate the elements of neuropathic pain. The VAS and PDQ scores did not differ significantly between PHI-positive and PHI-negative patients. A large neuropathic component was not found for herpes zoster itch, suggesting that neuropathic pain treatments may not able to adequately control the itch. Accordingly, we suggest that a more PHI-focused therapy is required to address this condition.

The accuracy of retrospective ratings of pain intensity was examined in a sample of 72 men and 36 women undergoing rehabilitation following anterior cruciate ligament (ACL) reconstructive surgery. Participants completed daily ratings of current, worst, and average pain intensity for the first 42 days of rehabilitation. Participants provided retrospective ratings of worst and average pain intensity twice for a 7-day period (on Days 7 and 21) and once for a 30-day period (on Day 30). Correlations between concurrent and retrospective pain ranged from .74 to .88. Retrospective pain ratings consistently overestimated concurrent pain ratings, but were generally not biased by current pain. The results suggest that retrospective pain ratings can substitute for concurrent pain ratings if the tendency toward overestimation is taken into account.
