RESUMEN

BACKGROUND: Rheumatic immune-related adverse events (R-irAEs) occur in 5-15% of patients receiving immune checkpoint inhibitors (ICI) and, unlike other irAEs, tend to be chronic. Herein, we investigate the factors influencing cancer and R-irAEs outcomes with particular focus on adverse effects of anti-inflammatory treatment. METHODS: In this prospective, multicenter, long-term, observational study, R-irAEs were comprehensively analyzed in patients with malignant melanoma (MM, n=50) and non-small cell lung cancer (NSCLC, n=41) receiving ICI therapy who were enrolled in the study between August 1, 2018, and December 11, 2022. RESULTS: After a median follow-up of 33 months, progressive disease or death occurred in 66.0% and 30.0% of MM and 63.4% and 39.0% of patients with NSCLC. Male sex (progression-free survival (PFS): p=0.013, and overall survival (OS): p=0.009), flare of a pre-existing condition (vs de novo R-irAE, PFS: p=0.010) and in trend maximum glucocorticoid (GC) doses >10 mg and particularly ≥1 mg/kg prednisolone equivalent (sex-adjusted PFS: p=0.056, OS: p=0.051) were associated with worse cancer outcomes. Patients receiving disease-modifying antirheumatic drugs (DMARDs) showed significantly longer PFS (n=14, p=0.011) and OS (n=20, p=0.018). Effects of these variables on PFS and/or OS persisted in adjusted Cox regression models. Additionally, GC treatment negatively correlated with the time from diagnosis of malignancy and the latency from ICI start until R-irAE onset (all p<0.05). R-irAE features and outcomes were independent of other baseline patient characteristics in both studied cancer entities. CONCLUSION: Male sex, flare of pre-existing rheumatologic conditions and extensive GC treatment appeared to be linked with unfavorable cancer outcomes, while DMARD use had a favorable impact. These findings challenge the current dogma of restrictive DMARD use for R-irAE and thus may pave the way to better strategies and randomized controlled trials for the growing number of patients with R-irAE.

RESUMEN

OBJECTIVES: Rheumatic immune-related adverse events (irAE) such as (poly)arthritis in patients undergoing immune checkpoint inhibitor (ICI) treatment pose a major clinical challenge. ICI therapy improves CD8+ T cell (CD8) function, but CD8 contributes to chronic inflammation in autoimmune arthritis (AA). Thus, we investigated whether immune functional and metabolic changes in CD8 explain the development of musculoskeletal irAE in ICI-treated patients. METHODS: Peripheral CD8 obtained from ICI-treated patients with and without arthritis irAEs and from AA patients with and without a history of malignancy were stimulated in media containing 13C-labelled glucose with and without tofacitinib or infliximab. Changes in metabolism, immune-mediator release, expression of effector cell-surface molecules and inhibition of tumour cell growth were quantified. RESULTS: CD8 from patients with irAE showed significantly lower frequency and expression of cell-surface molecule characteristic for activation, effector-functions, homing, exhaustion and apoptosis and reduced release of cytotoxic and proinflammatory immune mediators compared with CD8 from ICI patients who did not develop irAE. This was accompanied by a higher glycolytic rate and ATP production. Gene-expression analysis of pre-ICI-treated CD8 revealed several differentially expressed transcripts in patients who later developed arthritis irAEs. In vitro tofacitinib or infliximab treatment did not significantly change the immune-metabolic profile nor the capacity to release cytolytic mediators that inhibit the growth of the human lung cancer cell line H838. CONCLUSIONS: Our study shows that CD8 from ICI-treated patients who develop a musculoskeletal irAE has a distinct immune-effector and metabolic profile from those that remain irAE free. This specific irAE profile overlaps with the one observed in CD8 from AA patients and may prove useful for novel therapeutic strategies to manage ICI-induced irAEs.

RESUMEN

Pain in the musculoskeletal system and in the joints is what comes to mind first when people talk about rheumatic diseases. However, rheumatic diseases are multisystem disorders that can affect every organ system. Therefore, ocular manifestations are common and can occur in almost every rheumatic disease. On the one hand, they can even precede musculoskeletal manifestations. On the other hand, they can remain unrecognized without a thorough ophthalmologic examination in some disease entities. Consequently, a close cooperation between medical specialties is warranted, to prevent permanent impairment in vision or consequential damage to organs or joints.The following article thus focuses on the most important ocular manifestations of rheumatic diseases. For example, we address keratoconjunctivitis sicca as a complication in many rheumatic disorders, which include rheumatoid arthritis and, most importantly, Sjogren's syndrome. Furthermore, we cover uveitis and associated diseases such as spondyloarthritis or sarcoidosis. Also, we discuss giant cell arteritis as a rheumatological emergency. All in all, we aim to give a synopsis of clinical presentations, important diagnostic measures, and current therapeutic options of the above-mentioned disorders.

RESUMEN

BACKGROUND: Keeping up motivation to learn when socially isolated during a pandemic can be challenging. In medical schools, the COVID-19 pandemic required a complete switch to e-learning without any direct patient contact despite early reports showing that medical students preferred face-to-face teaching in clinical setting. We designed close to real-life patient e-learning modules to transmit competency-based learning contents to medical students and evaluated their responses about their experience. METHODS: Weekly e-learning cases covering a 10-week leading symptom-based curriculum were designed by a team of medical students and physicians. The internal medicine curriculum (HeiCuMed) at the Heidelberg University Medical School is a mandatory part of clinical medical education in the 6th or 7th semester. Case-design was based on routine patient encounters and covered different clinical settings: preclinical emergency medicine, in-patient and out-patient care and follow-up. Individual cases were evaluated online immediately after finishing the respective case. The whole module was assessed at the end of the semester. Free-text answers were analyzed with MaxQDa following Mayring`s principles of qualitative content analyses. RESULTS: N = 198 students (57.6% female, 42.4% male) participated and 1252 individual case evaluations (between 49.5% and 82.5% per case) and 51 end-of-term evaluations (25.8% of students) were collected. Students highly appreciated the offer to apply their clinical knowledge in presented patient cases. Aspects of clinical context, interactivity, game-like interface and embedded learning opportunities of the cases motivated students to engage with the asynchronously presented learning materials and work through the cases. CONCLUSIONS: Solving and interpreting e-learning cases close to real-life settings promoted students' motivation during the COVID-19 pandemic and may partially have compensated for missing bedside teaching opportunities.

RESUMEN

Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic inflammation of the joints. Untreated RA leads to a destruction of joints through the erosion of cartilage and bone. The loss of physical function is the consequence. Early treatment is important to control disease activity and to prevent joint destruction. Nowadays, different classes of drugs with different modes of action are available to control the inflammation and to achieve remission. In this review, we want to discuss differences and similarities of these different drugs.

RESUMEN

INTRODUCTION: Progress tests provide students feedback on their level of proficiency over the course of their medical studies. Peer-assisted learning and competency-based education have become increasingly important in medical education. Although progress tests have been proven to be useful as a longitudinal feedback instrument, there are currently no progress tests that have been created in cooperation with students or that focus on competency in medical education. In this study, we investigated the extent to which students can be included in the development of a progress test and demonstrated that aspects of knowledge related to competency can be represented on a competency-based progress test. METHODS: A two-dimensional blueprint for 144 multiple-choice questions (MCQs) covering groups of medical subjects and groups of competency areas was generated by three expert groups for developing the competency-based progress test. A total of 31 students from seven medical schools in Germany actively participated in this exercise. After completing an intensive and comprehensive training programme, the students generated and reviewed the test questions for the competency-based progress test using a separate platform of the ItemManagementSystem (IMS). This test was administered as a formative test to 469 students in a pilot study in November 2013 at eight medical schools in Germany. The scores were analysed for the overall test and differentiated according to the subject groups and competency areas. RESULTS: A pool of more than 200 MCQs was compiled by the students for pilot use, of which 118 student-generated MCQs were used in the progress test. University instructors supplemented this pool with 26 MCQs, which primarily addressed the area of scientific skills. The post-review showed that student-generated MCQs were of high quality with regard to test statistic criteria and content. Overall, the progress test displayed a very high reliability. When the academic years were compared, the progress test mapped out over the course of study not only by the overall test but also in terms of the subject groups and competency areas. OUTLOOK: Further development in cooperation with students will be continued. Focus will be on compiling additional questions and test formats that can represent competency at a higher skill level, such as key feature questions, situational judgement test questions and OSCE. In addition, the feedback formats will be successively expanded. The intention is also to offer the formative competency-based progress test online.
