2023 EULAR recommendations for the management of fatigue in people with inflammatory rheumatic and musculoskeletal diseases.

OBJECTIVES: Fatigue is prevalent in people with inflammatory rheumatic and musculoskeletal diseases (I-RMDs) and recognised as one of the most challenging symptoms to manage. The existence of multiple factors associated with driving and maintaining fatigue, and the evidence about what improves fatigue has led to a multifaceted approach to its management. However, there are no recommendations for fatigue management in people with I-RMDs. This lack of guidance is challenging for those living with fatigue and health professionals delivering clinical care. Therefore, our aim was to develop EULAR recommendations for the management of fatigue in people with I-RMDs. METHODS: A multidisciplinary taskforce comprising 26 members from 14 European countries was convened, and two systematic reviews were conducted. The taskforce developed the recommendations based on the systematic review of evidence supplemented with taskforce members' experience of fatigue in I-RMDs. RESULTS: Four overarching principles (OAPs) and four recommendations were developed. OAPs include health professionals' awareness that fatigue encompasses multiple biological, psychological and social factors which should inform clinical care. Fatigue should be monitored and assessed, and people with I-RMDs should be offered management options. Recommendations include offering tailored physical activity and/or tailored psychoeducational interventions and/or, if clinically indicated, immunomodulatory treatment initiation or change. Patient-centred fatigue management should consider the individual's needs and preferences, their clinical disease activity, comorbidities and other psychosocial and contextual factors through shared decision-making. CONCLUSIONS: These 2023 EULAR recommendations provide consensus and up-to-date guidance on fatigue management in people with I-RMDs.

Young people's perspectives on patient-reported outcome measures in inflammatory arthritis: results of a multicentre European qualitative study from a EULAR task force.

INTRODUCTION: Although patient-reported outcome measures (PROMs) are increasingly used in clinical practice and research, it is unclear whether these instruments cover the perspective of young people with inflammatory arthritis (IA). The aims of this study were to explore whether PROMs commonly used in IA adequately cover the perspective of young people from different European countries. METHODS: A multinational qualitative study was conducted in Austria, Croatia, Italy and the Netherlands. Young people with either rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), Still's disease, psoriatic arthritis (PsA) or spondyloarthritis (SpA), aged 18-35 years, participated in semistructured focus group interviews. Thematic analysis was used and data saturation was defined as no new emergent concepts in at least three subsequent focus groups. RESULTS: Fifty-three patients (21 with RA/JIA/Still's, 17 with PsA, 15 with SpA; 72% women) participated in 12 focus groups. Participants expressed a general positive attitude towards PROMs and emphasised their importance in clinical practice. In addition, 48 lower level concepts were extracted and summarised into 6 higher level concepts describing potential issues for improvement. These included: need for lay-term information regarding the purpose of using PROMs; updates of certain outdated items and using digital technology for data acquisition. Some participants admitted their tendency to rate pain, fatigue or disease activity differently from what they actually felt for various reasons. CONCLUSIONS: Despite their general positive attitude, young people with IA suggested areas for PROM development to ensure that important concepts are included, making PROMs relevant over the entire course of a chronic disease.

Anthracycline-induced cardiotoxicity in patients with paediatric bone sarcoma and soft tissue sarcoma.

OBJECTIVES: Anthracycline cardiotoxicity is an important side-effect in long-term childhood cancer survivors. We evaluated the incidence of and factors associated with anthracycline cardiotoxicity in a population of patients diagnosed with bone or soft tissue sarcoma. Materials and methods We retrospectively enrolled patients diagnosed with bone or soft tissue sarcoma, from 1995 to 2011, treated with anthracycline chemotherapy at our Centre and with a follow-up echocardiography carried out ⩾3 years from cardiotoxic therapy completion. Cardiac toxicity was graded using Common Terminology Criteria for Adverse Events version 4.0. RESULTS: A total of 82 patients were eligible. The median age at treatment was 11.9 years (1.44-18). We evaluated the median cumulative anthracycline dose, age at treatment, sex, thoracic radiotherapy, hematopoietic stem cell transplantation, and high-dose cyclophosphamide treatment as possible risk factors for cardiotoxicity. The median cumulative anthracycline dose was 390.75 mg/m2 (80-580). Of the 82 patients, 12 (14.6%) developed cardiotoxicity with grade ⩾2 ejection fraction decline: four patients were asymptomatic and did not receive any treatment; six patients were treated with pharmacological heart failure therapy; one patient with severe cardiomyopathy underwent heart transplantation and did not need any further treatment; and one patient died while waiting for heart transplantation. The median time at cardiac toxicity, from the end of anthracycline frontline chemotherapy, was 4.2 years (0.05-9.6). Cumulative anthracycline dose ⩾300 mg/m2 (p 0.04) was the only risk factor for cardiotoxicity on statistical analyses. CONCLUSIONS: In our population, the cumulative incidence of cardiotoxicity is comparable to rates in the literature. This underlines the need for primary prevention and lifelong cardiac toxicity surveillance programmes in long-term childhood cancer survivors.

Expression of the pol gene of human endogenous retroviruses HERV-K and -W in leukemia patients.

The human endogenous retroviruses (HERVs) are a family of endogenous retroviruses that integrated into the germ cell DNA of primates over 30 million years ago. HERV expression seems impaired in several diseases, ranging from autoimmune to neoplastic disorders. The purpose of this study was to evaluate the overall endogenous retroviral transcription profile in bone marrow (BM) samples. A total of 30 paediatric high-risk leukaemia patients (lymphoid and myeloid malignancies) were tested for HERVs virus gene expression. Our findings show that HERV-K expression was significantly higher in leukaemia patients when compared to healthy donors of a similar median age. We observed a significantly high expression of HERV-K in acute lymphoblastic leukemia (ALL) patients. In this study, we also found a relative overexpression of the endogenous retrovirus HERV-K in BM cells from the majority of leukemia samples analyzed, in particular in ALL. This overexpression might be related to lymphatic leukemogenesis and it warrants further investigations.

Endocrine late effects after total body irradiation in patients who received hematopoietic cell transplantation during childhood: a retrospective study from a single institution.

PURPOSE: To evaluate the effects of total body irradiation (TBI) on the endocrine system in adults treated with hematopoietic cell transplantation (HCT) during childhood. METHODS: We studied 40 patients who underwent HCT between 1988 and 2004, mainly for childhood cancer. In 23 patients, the conditioning regimen consisted of high-dose chemotherapy and TBI (TBI+). In the other 17 patients, who did not receive TBI (TBI-), HCT was performed after high-dose chemotherapy alone. RESULTS: Overall, 34% of patients in the TBI+ group showed growth hormone deficiency, compared with none of the patients in the TBI- group (P < 0.05). Leydig cell failure was found in 23% of patients in the TBI+ group and in 0% of the patients in the TBI- group. Elevated FSH levels, suggesting spermatogenesis damage, were found in all the patients receiving TBI and in 36% of the patients in the TBI- group (P < 0.001). Also, primary hypothyroidism was more common in TBI+ (34%) than in TBI- (5.8%) patients (P < 0.05). CONCLUSIONS: Our data indicate that endocrine late effects after HCT are more frequent in patients who received TBI, an observation that should be considered, even if the choice of the conditioning regimen is determined by the underlying condition in most cases.
