    Patients with Cancer and Immune Checkpoint Inhibitor-Induced Rheumatic irAEs Treated by DMARDs: The RHUMICI Single-Centre Retrospective Cohort

    by Emmanuel Massy, Julien Seiller, Muriel Piperno, Edith Bonnelye, Denis Maillet, Stéphane Dalle, Clara Fontaine-Delaruelle, Pierre-Jean Souquet, Julien Péron, Cyrille B. Confavreux

    Background/Objectives: Immune checkpoint inhibitors (ICIs) can lead to immune-related adverse events (irAEs), including rheumatic manifestations affecting 5–10% of treated patients. Managing rheumatic irAEs is challenging, as the use of glucocorticoids (GCs) or disease-modifying antirheumatic drugs (DMARDs) raises concerns about potentially impairing ICI antitumour efficacy. The oncological safety of DMARDs used specifically for rheumatic irAE management remains poorly characterised. Our objective was to evaluate the oncological safety profile of various rheumatic irAE treatment strategies. Methods: This single-centre retrospective observational study included 55 patients out of 104 who underwent rheumatological evaluation between July 2016 and October 2022. Patients were categorised into three groups: symptomatic treatment alone (analgesics/NSAIDs, n = 11), systemic glucocorticoids (GCs) only (n = 27), and conventional synthetic or biological disease-modifying antirheumatic drugs (csDMARDs and/or bDMARDs, n = 17). Overall survival (OS) and progression-free survival (PFS) were compared using a Kaplan–Meier analysis. Results: The three most frequent rheumatic irAE patterns were undifferentiated arthritis (n = 20), rheumatoid arthritis-like presentations (n = 14), and polymyalgia rheumatica (n = 11). Patients in the DMARD group had more severe irAEs (CTCAE grade ≥3: 30% vs. 15%, p < 0.01) and a higher baseline CRP (27.5 vs. 17.4 mg/L, p < 0.05), reflecting greater disease burden at treatment initiation. No significant difference was observed between groups for OS (p = 0.22) or PFS (p = 0.31) over a median follow-up of 34 months. Conclusions: No detrimental oncological safety signal was identified across rheumatic irAE treatment strategies, including GCs combined with csDMARDs or bDMARDs. These results support the cautious use of DMARDs as GC-sparing agents when clinically indicated, consistent with current EULAR and ESMO guidelines, and underline the need for prospective trials to optimise immunosuppressive management in ICI-treated patients.

  • Immunité de la métastase osseuse et effets de l'utilisation d'inhibiteurs de check point immunitaires

    by Emmanuel Massy

    Les métastases osseuses, complications graves et fréquentes des cancers solides, notamment du poumon, résultent d’interactions complexes entre cellules tumorales, osseuses et immunitaires. La colonisation osseuse par les cellules tumorales entraîne des déséquilibres dans l'homéostasie osseuse, souvent en stimulant les ostéoclastes, ce qui conduit à des lésions ostéolytiques, ostéoblastiques ou mixtes. Les nouveaux traitements des cancers par immunothérapie sont une avancée récente majeure mais la réponse des métastases osseuses à ces traitements semble moins claire. Cette étude vise à explorer les caractéristiques immunitaires des métastases osseuses dans des échantillons humains, en comparant cet environnement avec celui des tumeurs primaires pulmonaires, et à évaluer la possible role de ces spécificités sur l'efficacité des inhibiteurs de points de contrôle immunitaires (ICI) dans un modèle murin. Nos résultats montrent que les métastases osseuses sont associées à un microenvironnement immunosuppressif distinct, marqué par une diminution de l'activité des lymphocytes T cytotoxiques, une augmentation des macrophages M2 pro-tumoraux, ainsi qu’une infiltration accrue de lymphocytes T régulateurs, par rapport aux tumeurs pulmonaires primaires. La présence de macrophages M2 et de lymphocytes T régulateurs, associés à des cytokines immunosuppressives, contribue vraisemblablement à une tumeur « froide » sur le plan immunitaire, caractéristique des métastases osseuses. Ce phénomène limite l'efficacité des immunothérapies dans ce contexte, car les cellules tumorales échappent plus facilement à la surveillance immunitaire et favorisent la progression métastatique. Afin de mieux comprendre cette résistance, nous avons utilisé le traitement anti-PD-L1 dans un modèle murin de métastase osseuse pour évaluer ses effets sur la réponse immunitaire. Bien que le traitement stimule la prolifération et l'activité des lymphocytes T in vivo, nos données montrent qu'il reste inefficace pour inhiber la croissance tumorale osseuse. Ces observations soulignent les limites de l’immunothérapie par inhibition de points de contrôle dans les métastases osseuses, où l’environnement immunitaire particulier favorise l’évasion des cellules tumorales et une réponse immunitaire affaiblie. Cependant, l’analyse des cytokines et des voies moléculaires activées dans les métastases osseuses suggère des pistes pour contourner cette résistance. En ciblant des voies cytokiniques spécifiques comme l’IL6, le TGF-β et le MCSF, qui sont modulées par le traitement anti-PD-L1 in vitro, on pourrait remodeler le microenvironnement osseux. Ces cytokines semblent jouer un rôle clé dans la différenciation des macrophages vers un profil M2 et dans l’accroissement des lymphocytes Th17. Ainsi, une approche combinée visant à inhiber ces voies pourrait réduire la polarisation M2 et la présence de Th17, renforçant l’activité des lymphocytes T cytotoxiques dans les métastases osseuses. Ces découvertes mettent en lumière l'importance d'une stratégie thérapeutique intégrée pour traiter les métastases osseuses. En optimisant les ICIs par des traitements qui bloquent les voies d’immunosuppression spécifiques à l’os, il serait possible d’augmenter l'efficacité des immunothérapies dans les métastases osseuses. Ces travaux ouvrent la voie à de nouvelles perspectives thérapeutiques pour les patients atteints de métastases osseuses, souvent résistantes aux immunothérapies actuelles, et soulignent l'importance de prendre en compte les spécificités immunitaires de chaque site métastatique dans le développement de traitements plus efficaces.

    METHOFRACT, a methotrexate osteopathy multicentre cohort study

    by François Robin, Roba Ghossan, Nadia Mehsen-Cetre, Louise Triquet, Guillaume Larid, Guillaume Coiffier, Marine Mina, Marie Eva Pickering, Claire Barthe, Julien Paccou, et al.

    Methotrexate-induced osteopathy (MTX-IO) is a rare condition typically involving the lower limbs, especially tibia or foot fractures, among patients with well-controlled rheumatoid arthritis (RA) or psoriatic arthritis (PsA). This study aimed to identify the affected population, describe fracture characteristics and identify risk factors for poor clinical outcome. A multicentre retrospective study included patients with MTX-IO diagnosed by bone specialists or identified through French pharmacovigilance. The data collected included clinical presentation, imaging features, bone mineral density and biochemical markers. Between 2012 and 2024, 92 patients were included, predominantly postmenopausal women with seropositive RA. A history of major fractures was noted for 22% of the patients, and 56% presented osteoporosis at diagnosis. Fractures were most common in the tibial metaphysis (distal and proximal) (88%) and the foot bones (49%), with multiple fractures often present at diagnosis (76%), and frequently repeated fractures in the patients’ recent histories (63%). Diagnosis was conducted using MRI of the painful sites (84%), but bone scintigraphy was also used (41 patients, 45%). Management involved methotrexate discontinuation in 79% of the cases. Fracture healing and pain relief were achieved in 77% of the cases, with a significant difference in outcomes between those who discontinued methotrexate (91%) versus those who continued (29%) (p<0.001). MTX-IO is a rare but significant condition, especially among postmenopausal women with RA or PsA. Early diagnoses via MRI or bone scintigraphy and the discontinuation of methotrexate are critical, as stopping the drug significantly improves outcomes and prevents further fractures.

    Efficacy and safety of balneotherapy in rheumatology: a systematic review and meta-analysis

    by Ikram Aribi, Mikail Nourredine, Caroline Giroudon, Emmanuel Massy, Jean-Christophe Lega, Behrouz Kassai, Guillaume Grenet

    Objective The efficacy of balneotherapy in rheumatology remains unclear. We aimed to estimate its benefits and risks in rheumatology. Methods We conducted a systematic review of randomised trials assessing any European balneotherapy for a rheumatological indication in adults versus any control, on clinical outcomes. We searched PubMed, Cochrane Library, Embase and https://clinicaltrials.gov/ (up to 28 November 2023). We used the Cochrane risk of bias tool version 2, funnel plot and asymmetry tests. We used a random effects model with an inverse-variance weighting method for standardised mean difference (SMD) and risk ratio (RR). We used the Grading of Recommendations Assessment, Development and Evaluation approach for two primary outcomes, pain and quality of life (QoL) at 3 months, and two safety outcomes, withdrawal and any adverse event (AE). Results We included 29 trials in mechanical disorders, 9 in inflammatory diseases and 4 in fibromyalgia. The synthesis suggested a decrease in pain of a very low level of certainty (SMD: −0.72 (95% CI (−1.00; −0.44)), very serious risk of bias and of inconsistency, publication bias strongly suspected); an increase in QoL of a very low level of certainty (SMD: 0.56 (95% CI (0.37; 0.75)), very serious risk of bias and serious risk of inconsistency); inconclusive results regarding the risk of withdrawal (RR: 0.75 (95% CI (0.46; 1.20)), very serious risk of bias and serious risk of imprecision) and of AE (RR: 0.80 (95% CI (0.43; 1.50)), serious risk of bias and of inconsistency and very serious risk of imprecision). Conclusion The certainty of the effect of balneotherapy in rheumatology was very low. PROSPERO registration number CRD42023448206.
