The contribution of thoracic vertebral deformity and arthropathy to trunk pain in patients with chronic obstructive pulmonary disease (COPD)

Beyond breathing: Systematic review of global chronic obstructive pulmonary disease guidelines for pain management

CONTEXT

Patients with chronic obstructive pulmonary disease (COPD) experience pain as both symptom and comorbidity. There has been no evaluation of the recommendations for pain management in updated clinical practice guidelines (CPGs).

OBJECTIVES

Update the evidence on pain management, determine alignment of pain management recommendations with best-practice, and advocate for optimal pain management in patients with COPD.

METHODS

PubMed, Guideline International Network, Guideline Portal, Agency for Healthcare Research and Quality, National Institute for Healthcare Excellence, Scottish International Guidelines Network, Institute of Medicine, grey literature, national websites, and bibliographies were searched. CPGs available online for stable COPD produced by organizations representing reputable knowledge of COPD management were included. CPGs unavailable online, not translatable into English, or not including techniques within the defined scope were excluded. Researchers performed frequency counts for the verbatim terms "pain," "physical activity," "exercise," "rehabilitation," "physical therap(ist)/(y), "physiotherap(ist)/(y)," recorded context, and collected recommendations for pain management/treatment when present.

RESULTS

Of 32 CPGs, 24 included "pain" verbatim. Of these, 13 included recommendations for pain treatment/management. Common recommendations included opioids, pharmacological management, further medical assessment, and surgical intervention. Two CPGs referred to palliative care, one CPG discussed treating cough, and one discussed massage, relaxation, and breathing.

CONCLUSIONS

Pain management recommendations vary and are not aligned with evidence. Pain should be addressed in patients with COPD, whether directly or indirectly related to the disease. Reduction of variability in pain management and the disease burden is necessary. Pain management should include referrals to providers who can maximize benefit of their services.

Respiratory compromise in French bulldogs presented with intervertebral disc extrusion

BACKGROUND

French bulldogs hospitalised for the management of intervertebral disc extrusion (IVDE) are frequently affected by respiratory compromise, typically brachycephalic-associated upper respiratory obstruction and/or aspiration events. We evaluated the occurrence of such respiratory compromise events in French bulldogs presented to two referral hospitals.

METHODS

Clinical data for French bulldogs diagnosed with IVDE were retrospectively collated, including severity of neurological deficits, neuroanatomical localisation, diagnosis, details of respiratory compromise, treatment and outcome.

RESULTS

A total of 306 dogs diagnosed with IVDE were included. Sixty dogs (19.6%) experienced respiratory compromise, of which 31 dogs (10.1%) progressed to cyanosis, collapse or respiratory arrest.

LIMITATIONS

The study was limited by its retrospective nature. Furthermore, the duration of hospitalisation was not evaluated and the decision for euthanasia was often multifactorial.

CONCLUSION

One in five French bulldogs presented with IVDE experienced respiratory compromise. The detrimental welfare effects of this warrant further discussion.

Differences in the global exposure, mortality and disability of low bone mineral density between men and women: the underestimated burden in men

Talking about osteoporosis, we tend to focus on post-menopause women who are at increased risk due to estrogen depletion, while less attention has been paid to the disease in men. Currently, there is a lack of understanding about the difference of osteoporosis incidence and burden by sex. In this study, we used data from the Global Burden of Disease Study 2019 (GBD 2019) to compare the difference in the prevalence and burden of low bone mineral density (LBMD) between men and women, by location, year, age and socio-demographic index. We found the prevalence of LBMD was higher in women than in men. However, the age standardized mortality rate was greatly higher in men than in women. Using disability-adjusted life year (DALY) to measure the burden, we also observed higher age standardized DALY rate in men. Using sociodemographic index (SDI) as the measure of social development level, we found that higher mortality and DALY rates were mainly seen in middle and high SDI countries. Falls were the leading cause for of deaths and disabilities in both men and women with LBMD, followed by transport injuries. Fall-related mortality was higher in women, while transport injuries caused more deaths and disabilities in men. Conclusively, more attention should be paid to osteoporosis in men, and related policies, clinical practices, and guidelines are in need to reduce the burden of LBMD and osteoporosis in men.

Osteoporosis in Patients With Respiratory Diseases

Climate change, environmental pollution, and virus epidemics have sharply increased the number of patients suffering from respiratory diseases in recent years. Prolonged periods of illness and drug use increase the occurrence of complications in these patients. Osteoporosis is the common bone metabolism disease with respiratory disturbance, which affects prognosis and increases mortality of patients. The problem of osteoporosis in patients with respiratory diseases needs more attention. In this review, we concluded the characteristics of osteoporosis in some respiratory diseases including COPD, asthma, COVID-19, tuberculosis, and lung cancer. We revealed that hypoxia was the common pathogenesis of osteoporosis secondary to respiratory diseases, with malnutrition and corticosteroid abuse driving the progression of osteoporosis. Hypoxia-induced ROS accumulation and activated HIF-1α lead to attenuated osteogenesis and enhanced osteoclastogenesis in patients with respiratory diseases. Tuberculosis and cancer also invaded bone tissue and reduced bone strength by direct infiltration. For the treatment of osteoporosis in respiratory patients, oral-optimized bisphosphonates were the best treatment modality. Vitamin D was a necessary supplement, both for calcium absorption in osteogenesis and for improvement of respiratory lesions. Reasonable adjustment of the dose and course of corticosteroids according to the etiology and condition of patients is beneficial to prevent the occurrence and development of osteoporosis. Additionally, HIF-1α was a potential target for the treatment of osteoporosis in respiratory patients, which could be activated under hypoxia condition and involved in the process of bone remodeling.

Clinical and Psychological Impact of Chronic Pain in People with Chronic Obstructive Pulmonary Disease

Purpose

The presence of pain can be associated with an exaggerated negative cognitive and emotional response, leading to worsening of existing symptoms. This study aimed to describe the multifaceted impact of chronic pain on cognition, emotional and physical health in people with chronic obstructive pulmonary diseases (COPD) and to explore the clinical impact of pain.

Patients and Methods

A prospective, cross-sectional multicenter study was carried out in 68 people with COPD (COPD group) and 65 community-dwelling age-matched participants (control group). Participants were assessed for the presence of chronic pain, pain location, intensity and catastrophizing, pain-related fear (kinesiophobia), anxiety and depression, physical activity, and sleep duration. The COPD group also completed assessments of dyspnea, exercise tolerance (6-minute walk distance [6MWD]), and activities of daily living (ADL).

Results

The prevalence of pain was higher in the COPD group (85% vs 51%, p<0.001). The COPD group reported pain located in neck/shoulder, upper back, thorax and upper limbs, while the control group had more pain in the lower back. Pain catastrophizing and kinesiophobia were reported by 28% and 67% vs 9% and 42%, in the COPD and control groups respectively (both p<0.05). People with COPD and pain (n=58) reported greater dyspnea (p<0.001), and impairment in ADL (p<0.05), and lower 6MWD and physical activity (both p<0.01) compared to COPD participants without pain (n=10).

Conclusion

This study demonstrated that, compared to community-dwelling participants, there is a higher prevalence of chronic pain in people with COPD. Pain combined with dyspnea may impact adversely on cognitive function and lead to anxiety and depression, as well as greater impairment in exercise tolerance, physical activity, and ADL. These results suggested that it is necessary to assess the symptoms of chronic pain and inflect in chronic pain coping strategies.

The relationship between vertebral deformities and thoracic arthropathy with back pain in Chronic Obstructive Pulmonary Disease

OBJECTIVES

The aim of the study was to investigate the relationship between back pain and thoracic vertebral deformities and arthropathy in patients with COPD who underwent thorax CT scans to screen for lung nodules and cancer.

MATERIALS AND METHODS

The data of patients who underwent thoracic CT and pulmonary function tests (PFTs) between July 2019 and February 2020 were retrospectively reviewed. The patients were divided into two groups: the COPD (n = 64) and control groups (n = 101), according to the PFT results. The CT images were evaluated for vertebral deformities, osteoporosis and thoracic vertebral joint arthropathy, and the Spinal Deformity Index (SDI) was calculated.

RESULTS

Back pain was detected in 43.7% of the COPD patients and 20.9% of the controls. The patients with COPD had significantly higher rates of costotransverse, intervertebral, facet joint arthropathy, and osteoporosis than did the control group (P < .001). The OR analyses showed that the presence of a vertebral deformity (OR 4.42, 95% CI 2.26 - 8.63, P < .001), of facet joint arthropathy (OR 3.6, 95% CI 2.83-4.58, P < .001), and of costotransverse arthropathy (OR 2.20, 95% CI 1.47-2.77, P < .001) were associated with the presence of back pain. Although a strong positive correlation was found between the SDI and pain score, a moderate negative correlation was found between the FEV1% values and pain score.

CONCLUSIONS

Back pain was present in patients with COPD and was related to vertebral deformities and facet and costotransverse joint arthropathy. Additional studies are required to clarify the relationships of back pain with musculoskeletal system diseases, including cervical and lumbar spine arthropathy and vertebral deformities.

Pain Prevalence, Localization, and Intensity in Adults with and without COPD: Results from the Danish Health and Morbidity Survey (a Self-reported Survey)

Introduction

Pain is a clinical complication to chronic obstructive pulmonary disease (COPD) that interferes negatively with physical activity level (PAL), quality of life (QOL) and pulmonary interventions. Yet, research in pain characteristics including prevalence, localization, and intensity in people with COPD are sparsely researched.

Aim

To investigate self-reported pain prevalence, localization and intensity of pain in people with and without COPD, and to investigate the association between pain intensity and PAL among participants with COPD.

Methods

Data were derived from the Danish Health and Morbidity Survey in 2017. The study population was restricted to individuals aged ≥35 years. Data included pain intensity assessed on the Numeric Rating Scale (NRS) and localization, PAL, QoL, sleep disturbance, comorbidities, sociodemographic and behavioral factors.

Results

In all, 528 participants with COPD and 8184 participants without COPD (51% females, mean ±SD age 67.1±11.4 years) were analyzed. Pain prevalence within the past 14 days was significantly higher in participants with COPD vs nonCOPD (72.7% vs 57.7%, p<0.001) and mainly located in the limbs, thorax, and lower back. COPD was associated with the prevalence of chronic pain (≥6 months) (OR: 2.78, 95%CI: 2.32; 3.34, p<0.001). Participants with COPD reported a higher pain intensity compared to those with nonCOPD with a mean difference of 1.04 points (95%CI: 0.75; 1.32, p<0.001) on the NRS. In the adjusted multiple logistic regression analysis, pain intensity was negatively associated with odds of being physical active (OR: 0.72, 95%CI: 0.61; 0.85, p<0.001).

Conclusion

Pain is more prevalent in people with self-reported COPD. After adjustment for age and gender, COPD was associated with an elevated pain intensity. Sleep disturbance and multimorbidity had the most pronounced impacts on pain intensity in the multiple linear regression model. In participants with COPD, increased pain intensity was negatively associated with being physically active.

Prevalence and Characteristics of Pain in Patients of Chronic Obstructive Pulmonary Disease: A Cross-Sectional Study in China

The purposes of this study were to: (1) study the prevalence of pain in patients with mild-to-very severe chronic obstructive pulmonary disease (COPD) in China; (2) compare the differences in pain characteristics between stable COPD and acute exacerbation of COPD (AECOPD); (3) explore the clinical associations with pain in those with COPD. This cross-sectional study was conducted in China from October 24, 2017, to January 11, 2019. A face-to-face interview was conducted to collect data. The Chinese version of the brief pain inventory (BPI-C) was applied to investigate the pain characteristics in patients with COPD. Of the 901 patients in this study, 226 (25.1%) patients reported pain problems. The prevalence of pain in patients with mild to very severe COPD was 32.9%, 23.9%, 25.2%, and 23.5%, respectively (p = 0.447). According to the BPI-C results, 31.3% (31/99) of patients reported pain of AECOPD, compared to 24.3% (195/802) of stable COPD (p = 0.13). Reported pain intensity and pain interference evaluated by the BPI-C were significantly higher in AECOPD than stable COPD (p < 0.001, p < 0.05, respectively). Those with body mass index (BMI) ≥ 24kg/m² or COPD assessment test (CAT) score > 20 were significantly more likely to have pain problems than BMI < 24kg/m² (aOR = 1.568, a95IC = 1.132-2.170, p = 0.007) or CAT ≤ 20 (aOR= 1.754, a95IC = 1.213-2.536, p = 0.003). Pain was common in patients with both stable COPD and AECOPD. AECOPD patients had a significantly higher pain intensity than stable COPD. Overweight and CAT > 20 were significantly related to higher prevalence of pain.

The Role of Manual Therapy in Patients with COPD

Chronic obstructive pulmonary disease (COPD) is a respiratory condition associated with altered chest wall mechanics and musculoskeletal changes. In this narrative review, we describe the underlying musculoskeletal abnormalities in COPD, the reasons for applying manual therapy techniques, their method of application and clinical effects. A variety of manual therapy techniques have been applied in individuals with COPD, including soft tissue therapy, spinal and joint manipulation and mobilisation, and diaphragmatic release techniques. These have been prescribed in isolation and in conjunction with other treatments, including exercise therapy. When applied in isolation, transient benefits in respiratory rate, heart rate and symptoms have been reported. Combined with exercise therapy, including within pulmonary rehabilitation, benefits and their corresponding clinical relevance have been mixed, the extent to which may be dependent on the type of technique applied. The current practical considerations of applying these techniques, including intense therapist–patient contact and the unclear effects in the long term, may limit the broad use of manual therapy in the COPD population. Further high quality research, with adequate sample sizes, that identifies the characteristic features of those with COPD who will most benefit, the optimal choice of treatment approach and the longevity of effects of manual therapy is required.

Systematic Review of Pain in Clinical Practice Guidelines for Management of COPD: A Case for Including Chronic Pain?

Chronic pain is highly prevalent and more common in people with chronic obstructive pulmonary disease (COPD) than people of similar age/sex in the general population. This systematic review aimed to describe how frequently and in which contexts pain is considered in the clinical practice guidelines (CPGs) for the broad management of COPD. Databases (Medline, Scopus, CiNAHL, EMbase, and clinical guideline) and websites were searched to identify current versions of COPD CPGs published in any language since 2006. Data on the frequency, context, and specific recommendations or strategies for the assessment or management of pain were extracted, collated, and reported descriptively. Of the 41 CPGs (English n = 20) reviewed, 16 (39%) did not mention pain. Within the remaining 25 CPGs, pain was mentioned 67 times (ranging from 1 to 10 mentions in a single CPG). The most frequent contexts for mentioning pain were as a potential side effect of specific pharmacotherapies (22 mentions in 13 CPGs), as part of differential diagnosis (14 mentions in 10 CPGs), and end of life or palliative care management (7 mentions in 6 CPGs). In people with COPD, chronic pain is common; adversely impacts quality of life, mood, breathlessness, and participation in activities of daily living; and warrants consideration within CPGs for COPD.
