Levels of sCD163 in women rheumatoid arthritis: Relationship with cardiovascular risk markers

AIM

The soluble scavenger receptor differentiation antigen 163 (sCD163), a monocyte/macrophage activation marker, is related to cardiovascular mortality in the general population. This study aimed to evaluate their relationship between serum levels of sCD163 with cardiovascular risk indicators in rheumatoid arthritis (RA).

METHODS

A cross-sectional study was performed on 80 women diagnosed with RA. The cardiovascular risks were determined using the lipid profile, metabolic syndrome, and QRISK3 calculator. For the assessment of RA activity, we evaluated the DAS28 with erythrocyte sedimentation rate (DAS28-ESR). The serum levels of sCD163 were determined by the ELISA method. Logistic regression models and receiver operating characteristics (ROC) curve were used to assess the association and predictive value of sCD163 with cardiovascular risk in RA patients.

RESULTS

Levels of sCD163 were significantly higher in RA patients with high sensitivity protein C-reactive to HDL-c ratio (CHR)≥0.121 (p=0.003), total cholesterol/HDL-c ratio>7% (p=0.004), LDL-c/HDL-c ratio>3% (p=0.035), atherogenic index of plasma>0.21 (p=0.004), cardiometabolic index (CMI)≥1.70 (p=0.005), and high DAS28-ESR (p=0.004). In multivariate analysis, levels of sCD163≥1107.3ng/mL were associated with CHR≥0.121 (OR=3.43, p=0.020), CMI≥1.70 (OR=4.25, p=0.005), total cholesterol/HDL-c ratio>7% (OR=6.63, p=0.044), as well as with DAS28-ESR>3.2 (OR=8.10, p=0.008). Moreover, levels of sCD163 predicted CHR≥0.121 (AUC=0.701), cholesterol total/HDL ratio>7% (AUC=0.764), and DAS28-ESR>3.2 (AUC=0.720).

CONCLUSION

Serum levels of sCD163 could be considered a surrogate of cardiovascular risk and clinical activity in RA.

Behavioural change interventions encouraging clinicians to reduce carbon emissions in clinical activity: a systematic review

BACKGROUND

Clinical activity accounts for 70-80% of the carbon footprint of healthcare. A critical component of reducing emissions is shifting clinical behaviour towards reducing, avoiding, or replacing carbon-intensive healthcare. The objective of this systematic review was to find, map and assess behaviour change interventions that have been implemented in healthcare settings to encourage clinicians to reduce greenhouse gas emissions from their clinical activity.

METHODS

Studies eligible for inclusion were those reporting on a behaviour change intervention to reduce carbon emissions via changes in healthcare workplace behaviour. Six databases were searched in November 2021 (updated February 2022). A pre-determined template was used to extract data from the studies, and risk of bias was assessed. The behaviour change techniques (BCTs) used in the interventions were coded using the BCT Taxonomy.

RESULTS

Six full-text studies were included in this review, and 14 conference abstracts. All studies used a before-after intervention design. The majority were UK studies (n = 15), followed by US (n = 3) and Australia (n = 2). Of the full-text studies, four focused on reducing the emissions associated with anaesthesia, and two aimed at reducing unnecessary test ordering. Of the conference abstracts, 13 focused on anaesthetic gas usage, and one on respiratory inhalers. The most common BCTs used were social support, salience of consequences, restructuring the physical environment, prompts and cues, feedback on outcome of behaviour, and information about environmental consequences. All studies reported success of their interventions in reducing carbon emissions, prescribing, ordering, and financial costs; however, only two studies reported the magnitude and significance of their intervention's success. All studies scored at least one item as unclear or at risk of bias.

CONCLUSION

Most interventions to date have targeted anaesthesia or pathology test ordering in hospital settings. Due to the diverse study outcomes and consequent inability to pool the results, this review is descriptive only, limiting our ability to conclude the effectiveness of interventions. Multiple BCTs were used in each study but these were not compared, evaluated, or used systematically. All studies lacked rigour in study design and measurement of outcomes.

REVIEW REGISTRATION

The study was registered on Prospero (ID number CRD42021272526) (Breth-Petersen et al., Prospero 2021: CRD42021272526).

Follow-up of clinical activity and accumulated organic damage in a cohort of patients with systemic lupus erythematosus from the Yucatán Peninsula, Mexico (1995-2016)

INTRODUCTION

Systemic lupus erythematosus (SLE) is an autoimmune with variable severity, common in Hispanic and African-American individuals.

OBJECTIVE

To know the clinical activity and the accumulated damage, as well as the prevalence and incidence, in a dynamic cohort of patients with SLE from the Yucatan Peninsula (1995-2016).

PATIENTS AND METHODS

A cohort of 200 patients with SLE, medical service beneficiaries of the ISSSTE Regional Hospital of Mérida, Yucatán, was analysed for 22 years. Disease activity and accumulated damage were evaluated using the MEX-SLEDAI scale and the SLICC-ACR-DI, respectively, and its correlation with clinical and demographic variables.

RESULTS

185 female and 15 male patients were analysed. Average accumulated damage and activity indices during follow-up were 4.63 and 1.10, respectively. The activity index was significantly lower in females compared to males (4.36 vs 7.43), and the accumulated damage did not present a difference by sex. The manifestations associated with greater activity were the mucocutaneous and articular ones, and the organs with the greatest accumulated damage were the musculoskeletal, neurological and gonadal. A relationship between the indices was found with the evolution time, remissions/reactivations, and persistent activity. Mortality was related to persistent activity due to systemic vascular complications and kidney and liver failure. The annual incidence and prevalence of SLE calculated was 2.86% and 48.43% in Yucatán Peninsula.

CONCLUSIONS

The patients presented persistent activity, with mild to moderate reactivations, and accumulated damage more aggressive in men. The clinical activity decreases and increases the accumulated damage at a longer evolution time, with less kidney disease and greater survival, which suggests a more benign course in the population of the Yucatan Peninsula.

A multi-site prospective, observational study of physiotherapist independent prescribing activity across musculoskeletal clinics in the United Kingdom

OBJECTIVE

To establish how advanced practice physiotherapists in the UK working in the musculoskeletal specialty are utilising their independent non-medical prescribing skills.

DESIGN

Multi-site, prospective, descriptive observational study. Ethics reference No: ERN_19-0994).

METHOD

The study was conducted by seven advanced practitioners, across seven clinical sites representative of advanced musculoskeletal practice in the UK, between 1st October 2019-March 31, 2020. Advanced physiotherapy practitioner independent prescribers working in a variety of musculoskeletal specialty areas collected data across 5 contexts of musculoskeletal clinical service: first contact practice, primary care, community triage, secondary care orthopaedics, secondary care rheumatology and private practice. Quantitative data were analysed descriptively with qualitative data analysed/synthesised via thematic analysis.

RESULTS

Prescribing activity data for n = 2470 patients were collected. Prescribing activity was highest for the treatment of nociceptive pain (51.3%) and inflammation (39.6%). Most prescribing activity occurred in the first 2-6 weeks (34.1%) following onset of condition. Medicines optimisation accounted for most of prescribing activity (18.1%), followed by over-the-counter medication recommendation (15.5%). De-prescribing accounted for 10.8% of all prescribing activity recorded. Qualitative data were synthesised into 4 themes: multimodal physiotherapeutic approach, joint decision making and patient choice, working with complexity, and legal and regulatory restriction.

CONCLUSIONS

Physiotherapist independent prescribing was used within all health sectors in conjunction with advanced skills in musculoskeletal physiotherapy as part of a multimodal physiotherapeutic approach. Prescribing activity was dictated by the clinicians' clinical reasoning and use of joint decision-making. Prescribing activity for acute back and neuropathic radicular pain was limited secondary to recent reclassification of gabapentin and pregabalin.

HAE-AS: A Specific Disease Activity Scale for Hereditary Angioedema With C1-Inhibitor Deficiency

BACKGROUND AND OBJECTIVE

The activity of hereditary angioedema due to C1-inhibitor deficiency (C1-INH-HAE) varies between patients and within individual patients. Objective: This study aims to develop a disease activity scale for C1-INH-HAE (HAE-AS) with sound measurement properties.

METHODS

Eleven countries participated in a prospective multicenter cohort study. A clinical questionnaire was self-completed by 290 adult patients with C1-INH-HAE. Patients also completed 2 quality of life scales, the SF-36v2 and the HAE-QoL. Rasch analysis and classic psychometric methods were used to preselect a series of clinical items: number of attacks by location and number of treated attacks, emergency room visits, psychological/psychiatric treatment, missed school/workdays in the previous 6 months; general health; and impairment in everyday work/activities due to pain.

RESULTS

The mean (SD) age was 41.5 (14.7; range, 18-84) years, and 69% were females. The final 12-item Rasch model showed that the HAE-AS had satisfactory reliability (person separation index, 0.748), local item independence, unidimensionality, and no item bias by age or sex. The HAE-AS provided scores in a linear measure, with a mean of 10.66 (3.92; range, 0-30). Further analysis with classic psychometric methods indicated that the HAE-AS linear measure presented moderate-to-high convergent validity with quality of life scales (SF-36v2: physical component, r=-0.33; mental component, 0.555; HAE-QoL, -0.61), and good discriminative validity by age, sex, and disease severity (P<.05).

CONCLUSIONS

The HAE-AS is a short, valid, reliable, and psychometrically sound measure of the activity of C1-INH-HAE that could prove useful for research studies.

Coping strategies in relapsing-remitting multiple sclerosis non-depressed patients and their associations with disease activity

Few studies evaluated coping strategies in people with multiple sclerosis (pwMS) in relation to annualized relapse rate (ARR) and lesion load (LL). Overall, results might have been influenced by the inclusion of depressed patients. To investigate the coping strategies and their association to disease activity, we studied relapsing-remitting pwMS accurately selected to avoid the confounding effect of depression. Sixty-seven relapsing-remitting pwMS and 67 healthy subjects (HS) underwent to Coping Orientation to Problems Experienced (I-COPE) and Coping Inventory for Stressful Situation (CISS) and Beck Depression Inventory-II. Cognitive performances, ARR, physical disability and magnetic resonance imaging T2-LL were assessed for correlation with coping and depression scores. pwMS showed lower scores than HSs on social support and turning to religion subscales of I-COPE and on emotion dimension of CISS. In pwMS, higher ARR was related to higher positive attitude and lower score on the turning to religion subscale of I-COPE. The present study revealed a less employment of emotion-based coping strategies in pwMS. A scarce use of faith for support and a frequent adoption of a positive attitude were associated with an increase of MS activity in terms of ARR.

Association of cardiometabolic risk status with clinical activity and damage in systemic lupus erythematosus patients: A cross-sectional study

Cardiometabolic status is a key factor in mortality by cardiovascular disease (CVD) in systemic lupus erythematosus (SLE). This study evaluated the association of cardiometabolic risk status with clinical activity and damage in SLE patients. A cross-sectional study was conducted in 158 SLE patients and 123 healthy subjects (HS). Anthropometry, glucose, hs-CRP, lipid profile, oxLDL, sCD36, anti-oxLDL antibodies, and cardiometabolic indexes were evaluated. SLE patients had dyslipidemia, higher sCD36, anti-oxLDL antibodies, hs-CRP, and risk (OR > 2) to present Castelli score ≥ 4.5, HDL-C < 40 mg/dL and LDL-C ≥ 100 mg/dL. Disease evolution time was correlated with glucose and BMI, damage with TG, and clinical activity with TG, TG/HDL-C ratio, and Kannel index. Active SLE patients had risk (OR > 2) to present a Castelli score ≥ 4.5, Kannel score ≥ 3, TG/HDL-C ratio ≥ 3 and HDL-C < 40 mg/dL. In conclusion, SLE patients have high cardiometabolic risk to CVD related to disease evolution time, and clinical activity.

The impact of COVID-19 pandemic on surgical residency programmes in Italy: a nationwide analysis on behalf of the Italian Polyspecialistic Young Surgeons Society (SPIGC)

Introduction

Recently, Italy has been heavily hit by COVID-19 pandemic and today it is still one of the most affected countries in the world. The subsequent necessary lockdown decreed by the Italian Government had an outstanding impact on the daily life of the entire population, including that of Italian surgical residents’ activity. Our survey aims to evaluate the impact of COVID-19 on the training programme of Italian surgical residents.

Materials and methods

We designed a 12-item-electronic anonymous questionnaire on SurveyMonkey© web application. The survey was composed of different sections concerning demographic characteristics and impacts of COVID-19 on the concrete participation in clinical, surgical and research activities. Future perspectives of responders after the pandemic were also investigated.

Results

Eighty hundred responses were collected, and 756 questionnaires were considered eligible to be included in the study analysis. Almost 35 and 27% of respondents experienced, respectively, complete interruption of surgical and clinical activities. A subgroup analysis, comparing the COVID-19 impact on clinical activities with demographics data, showed a statistically significant difference related to specialties (p = 0.0062) and Italian regions (p < 0.0001). Moreover, 112 residents have been moved to non-surgical units dealing with COVID-19 or, in some case, they voluntarily decided to interrupt their residency programme to support the ongoing emergency.

Conclusion

Our survey demonstrated that COVID-19 pandemic has severely impacted the educational programme of Italian surgical residents. Despite many regional differences, this survey highlighted the overall shortage of planning in the re-allocation of resources facing this unexpected health emergency.

Increased interferon-1α, interleukin-10 and BLyS concentrations as clinical activity biomarkers in systemic lupus erythematosus

BACKGROUND AND OBJECTIVE

to analyse the association between interferon-1α (INF1α), interleukin-10 (IL-10) and BLyS concentrations and clinical activity in systemic lupus erythematosus (SLE).

PATIENTS AND METHODS

A cross-sectional, observational study of 142 SLE patients and 34 healthy controls was performed, through a complete blood and urine test and review of their medical history. Serum concentration of INF1α, IL-10 and BLyS was determined by colorimetric methods. A biostatistical analysis was performed with R (3.3.2.).

RESULTS

69% of our SLE patients showed at least one cytokine increased. INF1α, IL-10 and BLyS are higher in SLE patients than in healthy controls (P<.001, P=.005 and P=.043, respectively), being INF1α the most frequent. Patients were categorised according to low or high concentrations of the three cytokines. We found a significant association between increased IL-10/INF1α concentrations and a higher clinical activity measured by SELENA-SLEDAI (P<.0001) and, to a lesser extent, an association with increased INF1α/IL-10/BLyS concentrations. Elevated levels of IL-10/INF1α and INF1α/IL-10/BLyS related to increased C3-C4 consumption (P<.001 and P=.001 respectively) and anti-dsDNA titres (P=.001 and P=.002 respectively). Elevated INF1α/BLyS related to higher anti-dsDNA titres (P=.004) and ENA positivity (P<.001). Increased levels of INF1α/IL-10/BLyS related to positivity of ANAs (P<.001) and APL (P=.004).

CONCLUSIONS

INF1α, IL-10 and BLyS are higher in SLE patients than in healthy controls. Increased IL-10 levels, regardless of whether or not there were also increased levels of BLyS and/or INF1α, was the cytokine that best fit with clinical activity in SLE measured with classic methods.

Presentations, Signs of Activity, and Differential Diagnosis of Vitiligo

Vitiligo has a variety of presentations, including focal, acrofacial, segmental, and generalized forms. Thorough knowledge of these presentations is important to make the correct diagnosis. Signs of activity are important to recognize so that treatment is optimized. Clinical findings of confettilike depigmentation, trichrome and inflammatory vitiligo, and the Koebner phenomenon should alert the clinician that a patient's disease is likely to worsen. These patients may require systemic treatment to stabilize their disease. Many other skin disorders present with hypopigmentation or depigmentation and must be distinguished to determine the right diagnosis, advise the patient on prognosis, and prescribe the correct treatment.

Canadian Cancer Trials Group IND197: a phase II study of foretinib in patients with estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2-negative recurrent or metastatic breast cancer

In murine models, overexpression of the MET receptor transgene induces tumors with human basal gene expression characteristics supporting MET inhibition as a treatment strategy for triple-negative breast cancer (TNBC). Foretinib is an oral multi-kinase inhibitor of MET, RON, AXL, TIE-2, and VEGF receptors with anti-tumor activity in advanced HCC and papillary renal cell cancer. Patients with centrally reviewed primary TNBC and 0-1 prior regimens for metastatic disease received daily foretinib 60 mg po in a 2-stage single-arm trial. Primary endpoints were objective response and early progression rates per RECIST 1.1. In stage 2, correlative studies of MET, PTEN, EGFR, and p53 on archival and fresh tumor specimens were performed along with enumeration of CTCs. 45 patients were enrolled with 37 patients having response evaluable and centrally confirmed primary TNBC (cTNBC). There were 2 partial responses (ITT 4.7 % response evaluable cTNBC 5.4 %) with a median duration of 4.4 months (range 3.7-5 m) and 15 patients had stable disease (ITT 33 %, response evaluable cTNBC 40.5 %) with a median duration of 5.4 months (range 2.3-9.7 m). The most common toxicities (all grades/grade 3) were nausea (64/4 %), fatigue (60/4 %), hypertension (58/49 %), and diarrhea (40/7 %). Six serious adverse events were considered possibly related to foretinib and 4 patients went off study due to adverse events. There was no correlation between MET positivity and response nor between response and PTEN, EGFR, p53, or MET expression in CTCs. Although CCTG IND 197 did not meet its primary endpoint, the observation of a clinical benefit rate of 46 % in this cTNBC population suggests that foretinib may have clinical activity as a single, non-cytotoxic agent in TNBC (ClinicalTrials.gov number, NCT01147484).

Peripheral blood leptin and resistin levels as clinical activity biomarkers in Mexican Rheumatoid Arthritis patients

OBJECTIVE

To evaluate the association between the clinical activity of RA patients and serum adipocytokines (Leptin, Adiponectin and Resistin) and inflammatory cytokines.

METHODS

All RA patients fulfilled ACR 1987 criteria and were treated with DMARDs. Adipocytokine and inflammatory cytokine levels were evaluated using ELISA.

RESULTS

121 patients were included in the study. Stratifying according to DAS28 (low, moderate and high activity), there were significant differences for Leptin, Resistin, IL-6 and IL-17, however, no differences were seen for Adiponectin, TNFα or IL-1β. Clinical activity positively correlated with Leptin, Resistin, IL-17 and IL-6 levels, but not with Adiponectin, TNFα or IL-1β. Adiponectin levels negatively correlated with TNFα and positively correlated with IL-1β. IL-1β positively correlated with IL-6 and negatively correlated with TNFα and IL-17.

CONCLUSION

Circulating Leptin, Resistin, IL-6 and IL-17 levels positively correlate with RA clinical activity in a manner independent of the subject's BMI. Complex relationships between inflammatory cytokines were observed in RA patients suggesting that other metabolic or inflammatory factors could be involved.

[Evaluation of the concordance between biological markers and clinical activity in inflammatory bowel disease]

BACKGROUND AND OBJECTIVES

Endoscopy is the gold standard to assess disease severity in inflammatory bowel disease, although it is an invasive procedure. Clinical activity and biological markers have been routinely used to determine disease activity in a non-invasive manner. The aim of this study was to determine concordance between common biological markers (C reactive protein, orosomucoid, erythrocyte sedimentation rate, fibrinogen, platelets, leukocytes, neutrophils and haemoglobin) and clinical activity in inflammatory bowel disease.

PATIENTS AND METHOD

Consecutive patients with inflammatory bowel disease were included. Clinical activity was evaluated according to the Harvey-Bradshaw index in Crohn's disease and to the partial Mayo score in ulcerative colitis. Serum concentrations of the different biomarkers were analysed. Concordance between clinical activity and elevation of the serological biomarkers was determined using the kappa statistic.

RESULTS

In total, 350 patients were included (median age 46 years, Crohn's disease 59%). Eleven percent of patients had clinical activity. Crohn's disease patients had mild clinical activity in 44% of cases, moderate disease in 44% and only 12% of patients had severe clinical activity. In ulcerative colitis, patients had mild, moderate and severe clinical activity in 50, 42 and 8% of cases, respectively. None of the biomarkers included had an acceptable concordance with clinical activity (kappa statistic ≤ 0.30).

CONCLUSIONS

Concordance between serological biomarkers and clinical activity in inflammatory bowel disease is remarkably low.

[The association of fibromyalgia and systemic lupus erythematosus change the presentation and severity of both diseases?]

INTRODUCTION

The association of fibromyalgia (FM) and systemic lupus erythematosus (SLE) have been investigated, with conflicting results regarding the impact of a condition on the other.

OBJECTIVES

To determine the frequency of FM in a sample of patients with SLE treated at the Hospital Complex of Sorocaba (CHS) and the impact of FM in SLE activity and quality of life, as well as of SLE in FM.

MATERIAL AND METHODS

Descriptive and correlational study. Patients who met the American College of Rheumatology (ACR) criteria for SLE and/or FM were included. The total sample was divided into three groups: FM/SLE (patients with association of SLE and FM), SLE (SLE patients only) and FM (FM patients only). The following variables were used: Fibromyalgia Impact Questionnaire (FIQ), activity index of SLE (SLEDAI), Indices of Diagnostic Criteria for Fibromyalgia 2010 (SSI end GPI) and SF-36.

RESULTS

The prevalence of patients with FM among SLE patients was 12%. FIQ showed no difference between groups, indicating that SLE did not affect the impact caused by FM alone. The presence of FM in SLE patients did not influence the clinical activity of this disease. A strong impact of FM on the quality of life in patients with SLE was observed; the opposite was not observed.

CONCLUSIONS

The prevalence of FM observed in SLE patients is 12%. The presence of FM adversely affects the quality of life of patients with SLE.

Low DPP4 expression and activity in multiple sclerosis

Multiple sclerosis (MS) is a prototypic Th1/Th17 chronic autoimmune disease of the central nervous system. Dipeptidyl peptidase 4 (DPP4 or CD26) is a multifunctional molecule involved in autoimmune diseases' pathophysiology. We sought to integrate disparate pieces of data and analyze the plasma levels of sDPP4, DPP activity and DPP4 surface expression on T-cells in 129 MS patients with different clinical forms and 53 healthy controls, across two independent cohorts. Herein, we provide new evidence that sDPP4 concentration and DPP activity are significantly lower in MS patients than controls (p < 0.0001 and p < 0.01, respectively). In contrast, the frequency of circulating CD8(+)DPP4(hi) T-cells (p = 0.02) was increased in MS patients. This is the first study that simultaneously analyzes DPP4 expression and function in a large cohort of MS patients. Our data indicate a putative role for DPP4 in MS pathophysiology and suggest that a deeper understanding of surface versus shed DPP4 biology is warranted.

Mucosal healing and deep remission: What does it mean?

The use of specific terms under different meanings and varying definitions has always been a source of confusion in science. When we point our efforts towards an evidence based medicine for inflammatory bowel diseases (IBD) the same is true: Terms such as “mucosal healing” or “deep remission” as endpoints in clinical trials or treatment goals in daily patient care may contribute to misconceptions if meanings change over time or definitions are altered. It appears to be useful to first have a look at the development of terms and their definitions, to assess their intrinsic and context-independent problems and then to analyze the different relevance in present-day clinical studies and trials. The purpose of such an attempt would be to gain clearer insights into the true impact of the clinical findings behind the terms. It may also lead to a better defined use of those terms for future studies. The terms “mucosal healing” and “deep remission” have been introduced in recent years as new therapeutic targets in the treatment of IBD patients. Several clinical trials, cohort studies or inception cohorts provided data that the long term disease course is better, when mucosal healing is achieved. However, it is still unclear whether continued or increased therapeutic measures will aid or improve mucosal healing for patients in clinical remission. Clinical trials are under way to answer this question. Attention should be paid to clearly address what levels of IBD activity are looked at. In the present review article authors aim to summarize the current evidence available on mucosal healing and deep remission and try to highlight their value and position in the everyday decision making for gastroenterologists.
