PsA has a prevalence of up to 1%, affecting ~20% of people suffering with psoriasis. PsA is frequently accompanied by metabolic syndrome (MetS), and both conditions are characterised by a chronic pro-inflammatory state, with several key cytokines in PsA (interleukin (IL)-17 and IL-23) also elevated in those with MetS. This narrative review aims to provide an update on MetS in PsA, focusing on its prevalence, pathogenesis, prognosis, treatment interactions and future therapeutic options. MetS is particularly prevalent in PsA compared to other inflammatory arthritides. Cohort studies indicate a higher risk of PsA in individuals with obesity, while Mendelian randomization studies link childhood obesity, insulin resistance, and dyslipidaemia to PsA. Weight loss interventions have been shown to reduce disease activity in PsA. Additionally, MetS negatively impacts the efficacy of tumour necrosis factor inhibitor (TNFi) drugs in treating PsA. Drugs given for PsA may also affect the conditions constituting MetS. Leflunomide has been shown to reduce body weight but also increase blood pressure. TNFi drugs lead to weight gain but reduce cardiovascular risk. Janus kinase inhibitors increase lipid levels and cardiovascular risk among high-risk groups. Anti-IL-17 and anti-IL-12/IL-23 drugs may cause a short-term increase in cardiovascular risk, although the long-term effects have yet to be established. Weight loss represents an unexplored avenue for disease modification in PsA, alongside a plethora of general health benefits. Dietary and exercise modifications are the cornerstone of weight management but vary substantially across individuals. Novel therapies to treat weight loss, such as glucagon-like peptide 1 agonists and sodium-glucose cotransporter 2 inhibitors, may prove useful alongside disease-modifying therapies for those with PsA and MetS and should be investigated as potential therapeutic adjuncts.</p>","PeriodicalId":23056,"journal":{"name":"Therapeutic Advances in Musculoskeletal Disease","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11331474/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142005340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This report presents a case involving severe multiple vertebral fractures due to PLO with low bone mineral density (BMD) and heightened bone turnover. A 39-year-old primiparous Japanese woman reported low back pain (LBP) starting at 28 weeks of pregnancy. The pain temporarily improved after delivery, although the LBP recurred and worsened 2 months into breastfeeding. Thereafter, the patient visited the Obstetrics and Orthopedic departments. Plain radiographs of the thoracic and lumbar spine showed loss of vertebral body height at the T4–12 and L1–3,5 vertebrae, leading to a diagnosis of 13 fractured vertebrae. BMD and serum bone turnover markers revealed low bone density and heightened bone turnover. In the absence of any identified alternative cause of secondary osteoporosis, the diagnosis was severe PLO with 13 vertebral fractures related to pregnancy and lactation. After treatment with bisphosphonates and an active vitamin D analog, the patient exhibited an increased BMD and normalization of bone turnover and resumed regular daily activities. Although the optimal PLO treatment strategy remains uncertain, bisphosphonates are an option; however, bisphosphonates can potentially affect the fetus through placental transfer. Therefore, careful consideration is required for patients planning pregnancy. Despite bisphosphonates’ widespread use and cost-effectiveness, selecting PLO medications involves multiple factors, necessitating further research.","PeriodicalId":23056,"journal":{"name":"Therapeutic Advances in Musculoskeletal Disease","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141863239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This enables direct confirmation of a suspected diagnosis within the examination room without further referrals. Rheumatologists can ask additional questions and explain findings to their patients while performing ultrasound, preferably in fast-track clinics to prevent vision loss. Vascular ultrasound for suspected vasculitis was recently integrated into rheumatology training in Germany. New European Alliance of Associations for Rheumatology recommendations prioritize ultrasound as the first imaging tool for suspected GCA and recommend it as an imaging option for suspected TAK alongside magnetic resonance imaging, positron emission tomography and computed tomography. Ultrasound is integral to the new classification criteria for GCA and TAK. Diagnosis is based on consistent clinical and ultrasound findings. Inconclusive cases require histology or additional imaging tests. Robust evidence establishes high sensitivities and specificities for ultrasound. Reliability is good among experts. Ultrasound reveals a characteristic non-compressible 'halo sign' indicating intima-media thickening (IMT) and, in acute disease, artery wall oedema. Ultrasound can further identify stenoses, occlusions and aneurysms, and IMT can be measured. In suspected GCA, ultrasound should include at least the temporal and axillary arteries bilaterally. Nearly all other arteries are accessible except the descending thoracic aorta. TAK mostly involves the common carotid and subclavian arteries. Ultrasound detects subclinical GCA in over 20% of polymyalgia rheumatica (PMR) patients without GCA symptoms. Patients with silent GCA should be treated as GCA because they experience more relapses and require higher glucocorticoid doses than PMR patients without GCA. Scores based on intima-thickness (IMT) of temporal and axillary arteries aid follow-up of GCA, particularly in trials. The IMT decreases more rapidly in temporal than in axillary arteries. Ascending aorta ultrasound helps monitor patients with extracranial GCA for the development of aneurysms. Experienced sonologists can easily identify pitfalls, which will be addressed in this article.</p>","PeriodicalId":23056,"journal":{"name":"Therapeutic Advances in Musculoskeletal Disease","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11155338/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141284810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
