Cause for Concern
A recent publication in Arthritis Care & Research explored the effect of opioid use and other factors—such as body mass index, age, level of education and health status—on the outcomes of patients with end-stage osteoarthritis having surgery. The study revealed that a large proportion of osteoarthritis patients—up to one third—are using opioids. Furthermore, opioid use was higher in younger individuals (those under 65 years of age) and those experiencing symptoms of depression. “Our findings provide compelling evidence that more rigorous guidelines, and effective and timely alternatives are needed to protect individuals with osteoarthritis from the potential harms of opioid use. Also, given that recent studies have linked opioid use to worse surgical outcomes, carefully considering patient factors, such as age and mental health, could help to counteract these effects and improve the lives of those with osteoarthritis” says Dr. Raja Rampersaud.
Differentiating Psoriatic Arthritis from Osteoarthritis
It is often difficult to distinguish Psoriatic Arthritis (PsA) from Osteoarthritis (OA), the most common form of arthritis, because both forms of arthritis affect similar joints (knees, hips, finger joints, etc.), have common features on x-rays, and have no reliable blood tests. Therefore, a recent
publication in Annals of the Rheumatic Diseases by Rheumatologists and Orthopaedic Surgeons in the Arthritis Program aimed to identify proteins in the blood that differentiate PsA from OA. Through a series of analyses of blood samples, a panel of four markers (cartilage oligomeric matrix protein, resistin, monocyte chemoattractant protein 1 and nerve growth factor) strongly differentiated PsA from OA. Further follow up studies will be conducted to confirm these findings and develop a diagnostic test for PsA.
Disease Course Patterns in Systemic Lupus Erythematosus
Disease activity in systemic lupus erythematosus (SLE) follows three different courses: long quiescent, relapsing remitting and persistently active, but the patterns of disease course since diagnosis remain unknown. A recent
publication in Lupus, led by Dr. Urowitz over a period of 10 years, aimed to assess the prevalence and characteristics of disease course. Relapsing-remitting course manifested in approximately 70% of SLE patients, whereas prolonged remission and persistently active courses each manifested in 10% of SLE patients. Further, early response to treatment was associated with a less severe course and better prognosis.
Mesenchymal Stromal Cells Clinical Trial in Osteoarthritis
Dr. Sowyma Viswanathan, Dr. Jas Chahal and other members of the Arthritis Program at UHN recently published the results of the
first-in-Canada autologous bone marrow mesenchymal stromal cells (MSCs) trial on 12 mid- to late-stage knee osteoarthritis patients. This clinical trial demonstrated safety and feasibility of dosing MSCs, as well as significant clinical and statistical improvements in patient-reported outcomes. Furthermore, there were decreased levels of pro-inflammatory monocytes/macrophages and inflammatory cytokines post-MSC treatment. MSC donor heterogeneity was a significant factor. The authors were able to curate a panel of anti-inflammatory genes that was highly correlated with patient outcomes, which suggests that these panel of genes may be used to predict MSC clinical potency.
Opioids and Pain
The effects of opioids on chronic pain are uncertain, whereas the harms found to be associated with prescription opioids include diversion, addiction, overdose, and death. In this meta-analysis of RCTs of patients with chronic non-cancer pain
published in JAMA, evidence from high-quality studies showed that opioid use was associated with statistically significant but small improvements in pain and physical functioning, and increased risk of vomiting compared with placebo. Comparisons of opioids with non-opioid alternatives suggested that the benefit for pain and functioning may be similar, although the evidence was from studies of only low to moderate quality.
Patient Outcomes in Osteoarthritis
publication in Arthritis Research & Therapy by the Viswanathan Laboratory investigated the role of immune cells, particularly monocytes/macrophages in OA pathology. Monocytes/macrophages were the most abundant immune cells in the synovial fluid of OA patients. Moreover, a specific subset of these monocytes/macrophages correlated with patient reported outcomes including joint stiffness, joint function and quality of life, even when adjusted for age, gender and body mass index. These monocytes/macrophages may have a role in potential adaptive immune responses. This was the first clinical cohort study to associate specific subtypes of monocytes/macrophages with patient reported outcomes.
Putting Labels on Protein Behaviour
publication in Nucleic Acids Research by the Jurisica Lab reported a substantial expansion of a database started in 2005. The database now includes protein interactions for 18 species, providing tissue specificity of the interactions, the diseases they are associated with, and whether they might respond to a known drug. For human, the database covers 969,843 interactions across 19,250 proteins, and annotates them with 133 tissues (including detailed joint-related tissues and 38 brain structures from Allen Brain Atlas), 91 disease conditions (including neurodegenerative diseases), drug targets (including enzymes, ion channels, receptors, and transporters), and many other contexts.
The Course of Back Pain in Canadians
publication in Arthritis Care & Research aimed to identify and describe back pain (BP) trajectory groups and to compare indicators of health status, medication, and healthcare use by these groups. The authors found that almost one-in-five people with BP experience a persistent trajectory with associated increased pain, disability, and healthcare use. Further research is needed to determine whether the identified groups represent different diagnoses, which may provide insights to the selection of stratified treatments and aid designing early prevention and management strategies in the population.
