Subjective sleep disturbances at the time of diagnosis in patients with polymyalgia rheumatica and in patients with seronegative elderly-onset rheumatoid arthritis. A pilot study

Absence of Long-Lasting Morning Stiffness at the Time of Diagnosis as Paraneoplastic Warning in Patients with Polymyalgia Rheumatica (PMR): Data from Italian Single-Center Study

BACKGROUND

There is little literature on the paraneoplastic value of the absence of long-lasting morning stiffness (MS) at the time of diagnosis of polymyalgia rheumatica (PMR). We investigated whether and to what extent this finding was related to the probability of diagnosing a neoplasia.

PATIENTS AND METHODS

This was an observational, retrospective, single-center cohort study. We enrolled all patients consecutively referred to our rheumatologic outpatient clinic between January 2015 and December 2020, who could be classified as PMR according to 2012 EULAR/ACR criteria. In particular, we assessed all patients scoring a minimum of five points with a combination of clinical and ultrasound (US) criteria. The exclusion criteria were as follows: (a) follow-up duration <two years; (b) malignancy prior to PMR; (c) first-degree familiarity of malignancy; (d) incomplete data; and (e) diagnostic change during follow-up in different rheumatologic diseases.

RESULTS

143 patients (108 women; median age: 71.5 years) were enrolled, and 35 of them did not have long-standing MS at the time of PMR diagnosis. In 10 patients (6.9%), a neoplasia was diagnosed in the first 6 months of follow-ups; among these, 7 did not have long-lasting MS. Among the remaining 133 PMR patients without subsequent malignancy, 28 did not have long-lasting MS. The odds of cancer were 0.114 (C.I. 95% 0.028, 0.471). Long-lasting MS was inversely associated with the development of neoplasias. In all eight PMR patients diagnosed with solid cancers during follow-ups, the removal of the neoplastic mass led to a fast disappearance of clinical, ultrasound and laboratory findings, thus supporting the diagnosis of paraneoplastic PMR. Finally, a positive response to glucocorticoids (GCs) was present in 100% of the 28 PMR patients without long-lasting MS at the time of diagnosis and without neoplasia during their follow-ups. On the contrary, a positive response to GCs was present in 71% of PMR patients without long-lasting MS and neoplasias during follow-up. Among the variables we assessed, a positive response to GCs was the only one that was statistically significant (p < 0.0001). These data suggested that an inadequate response to GCs in PMR patients without long-lasting MS at the time of diagnosis should strengthen investigations to rule out neoplasias.

CONCLUSIONS

The absence of long-standing MS at the time of diagnosis can be a paraneoplastic warning in patients classified as PMR. A thorough investigation is therefore needed in this subset of patients to rule out neoplasia, before diagnosing an idiopathic PMR and starting treatment with GCs.

Differentiating between Seronegative Elderly-Onset Rheumatoid Arthritis and Polymyalgia Rheumatica: A Qualitative Synthesis of Narrative Reviews

Elderly-onset rheumatoid arthritis (EORA) is prevalent among older patients, and its incidence is increasing due to aging societies. However, differentiating between EORA and polymyalgia rheumatica (PMR) is challenging for clinicians and hinders the initiation of effective treatment for rheumatoid arthritis among older generations, thereby allowing its progression. Therefore, we conducted a qualitative synthesis of narrative reviews via meta-ethnography regarding seronegative EORA diagnosis to clarify the methods to differentiate seronegative EORA from PMR. Three databases (PubMed, EMBASE, and Web of Science) were searched for relevant reviews published between January 2011 and October 2022. The extracted articles were synthesized using meta-ethnography, and 185 studies were selected following the protocol. Seven reviews were analyzed, and four themes and nine concepts were identified. The four themes included difficulty in differentiation, mandatory follow-up, and factors favoring rheumatoid arthritis and those favoring PMR. Factors favoring seronegative EORA and PMR should be considered for effective diagnosis and prompt initiation of disease-modifying anti-rheumatic drugs. Mandatory and long follow-ups of suspected patients are essential for differentiating the two diseases. The attitude of rheumatologists toward tentatively diagnosing seronegative EORA and flexibly modifying their hypotheses based on new or altered symptoms can aid in effective management and avoiding misdiagnosis.

The Analgesic Effect of Dexmedetomidine Loaded with Nano-Hydrogel as a Novel Nano-Drug Delivery System for Thoracic Paravertebral Block After Thoracic Surgery

Objective: To understand the effect of dexmedetomidine (Dex) thoracic paravertebral block combined with an injectable nano-drug delivery system in postoperative analgesia after thoracic surgery, an injectable nano-drug delivery system. Methods: Dex-loaded nano-hydrogel was first prepared in this study and its characteristics and drug release performance in vitro was investigated. Then, it was applied to the postoperative analgesia of 140 patients undergoing thoracic surgery. Results: It was found that the loading efficiency reached the highest when the ratio of Dex to injectable nano-hydrogel was 1:1; and at pH = 7.5, the cumulative release of 95.4%. The visual analogue scale (VAS) score and cumulative effective pressure times of analgesia pump in the observation group were lower than those of the control group. The sleep time per day and satisfaction of analgesia within 48 h in patients from the observation group were higher than those of the control group. The proportion of patients with remedial analgesia within 48 hours, and the proportion of patients with nausea and vomiting were significantly lower in patients treated with Dex-loaded with nano-hydrogel. Conclusion: Injectable nano-drug delivery system had good drug release and combination of Dex thoracic paravertebral block and nano-drug delivery system could significantly relieve pain after thoracic surgery and improve patients’ sleep quality.

Feasibility and usefulness of a fast-track clinic for patients suspected of polymyalgia rheumatica: notes for a work schedule through a narrative review of published literature

Objectives

Fast-track clinics (FTC) have been introduced in different fields and have been reporting significant outcomes in terms of reducing mortality, morbidity, and financial costs. To date, scarce evidence is available for FTC specific for patients suspected of polymyalgia rheumatica (PMR). The primary aim of our paper is to provide an overview of the clinical impact of PMR on patients and the healthcare system by analysing multiple aspects: the median time from onset of symptoms to diagnosis and the burden of the disease both on the healthcare system costs and on patients' quality of life (QoL). Secondarily, based on these data, we aim to discuss the potential advantages and feasibility of a PMR FTC in everyday clinical practice.

Material and methods

We performed a narrative non-systematic review (PRISMA protocol not followed) of PubMed and Medline (OVID interface) with the following MeSH terms: [polymyalgia rheumatica AND diagnosis OR diagnosis, delayed OR patient care OR early diagnosis OR length of stay OR costs OR healthcare system OR quality of life] or [polymyalgia rheumatica AND glucocorticoids AND side effects]. We decided to exclude every paper that did not report raw data in terms of diagnostic time or delay, hospitalization rate, socio-economic costs on the healthcare system, patients' QoL, and glucocorticoids-related events in PMR patients. Papers focused primarily on giant cell arteritis patients with overlapping PMR were also excluded. Abstract archives of the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR) congresses of the last 10 years were screened and included in the search if raw data were available. Each paper's reference list was scanned for additional publications meeting this study's aims. When papers reported data partially presented in previous articles, we opted to use the most recently published data.

Results

According to our literature review, a PMR FTC might lighten the burden of the disease. Nevertheless, its feasibility depends mostly on the resources of the national health system and of the territorial health district, which are heterogeneously limited. The usefulness of PMR FTCs depends on closer collaboration with the general practitioner because he/she is the first clinician to visit patients with PMR.

Conclusions

Polymyalgia rheumatica fast-track clinics might lighten the burden of the disease. However, it has some limits that should carefully assessed in planning health policies.

Not just pain and morning stiffness duration in the daily experience of patients with polymyalgia rheumatica. Does the rheumatologist listen to all patient-reported outcomes?

Patient-reported outcomes (PROs) provide a means for patients to communicate with their care teams about their disease. Polymyalgia rheumatica (PMR) is considered to be one of the most common inflammatory rheumatic diseases in older adults. The Visual Analogue Scale (VAS) of pain is the only PRO assessed by the PMR activity score (PMR-AS), which is still the only validated score for monitoring disease activity in patients affected with PMR. Other PROs such as fatigue, sleep disturbances, depressive symptoms, and patient’s perspective related to adverse effects of prednisolone are still unmet needs. This short communication suggests the gerontorheumatological outpatient clinic as an answer.
