Clonal T cell populations scarcely impair patients with rheumatic diseases: a prospective long-term follow up study.

Background: Clonal T cell populations are frequently detected in patients with rheumatic diseases. The relevance of this finding is often uncertain, as the clinical spectrum can range from being asymptomatic to T cell leukemia. Former studies suggested that certain anti-rheumatic drugs might influence the course of the clonal T cell populations.

Psychological impact of autologous hematopoietic stem cell transplantation in systemic sclerosis patients and influence of resilience.

Objective: In severe cases of systemic sclerosis (SSc), autologous hematopoietic stem cell transplantation (aHSCT) is superior compared to cyclophosphamide. But treatment related morbidity and mortality have to be considered. To date, data on major physical and psychological impacts of aHSCT are scarce.

Use of Janus kinase inhibitors before and after European Medicines Agency safety recommendations: a retrospective study.

Background: Safety recommendations for Janus kinase inhibitors (JAKi) issued by the European Medical Agency (EMA) in 2023 could potentially influence treatment patterns for rheumatoid arthritis (RA) drugs, but little is known about the impact of these recommendations in routine clinical care.

Methods: We retrospectively analyzed the German RHADAR rheumatology database for adult patients with RA and documentation of a new therapy with a JAKi, tumor necrosis factor inhibitor (TNFi), or interleukin-6 receptor inhibitor (IL-6Ri). Data were grouped into half-yearly intervals from quarter (Q)2/2020 to Q3/2023.

Vaccination status of patients with primary immunodeficiencies in Germany-a multicentric epidemiologic analysis.

Background: Vaccinations represent an easily accessible, safe, and important method for preventing infections. Patients with primary immunodeficiencies (PID) are more susceptible to infections and should receive an extended spectrum of immunizations in many countries.

Methods: Between January 2019 and May 2020, vaccination certificates of 70 patients with PID from the regions of Würzburg and Hanover in Germany were evaluated.

Vignette-based comparative analysis of ChatGPT and specialist treatment decisions for rheumatic patients: results of the Rheum2Guide study.

Background: The complex nature of rheumatic diseases poses considerable challenges for clinicians when developing individualized treatment plans. Large language models (LLMs) such as ChatGPT could enable treatment decision support.

Objective: To compare treatment plans generated by ChatGPT-3.

The exercise-app Axia for axial spondyloarthritis enhances the home-based exercise frequency in axial spondyloarthritis patients - A cross-sectional survey.

Background: Patients with axial spondyloarthritis (axSpA) benefit from regular home-based exercise (HbE). In spite of recommendations, a relevant proportion of German axSpA patients does not adhere to recommended HbE practices. To enhance HbE care, we developed the novel digital therapeutic (DTx) "Axia" compliant with the European medical device regulation (MDR).

Immunogenicity of tick-borne-encephalitis-virus-(TBEV)-vaccination and impact of age on humoral and cellular TBEV-specific immune responses in patients with rheumatoid arthritis.

Inactivated vaccines, such as tick-borne-encephalitis-virus-(TBEV) vaccine, have been discussed as less immunogenic in elderly and in immunocompromised patients. In this controlled cross-sectional cohort study, the antibody and cellular responses after TBEV-vaccination were investigated in 36 rheumatoid arthritis (RA) patients and 112 healthy controls (HC) by evaluating IgG-anti-TBEV concentration, neutralization and relative avidity index (RAI). Cellular reactivity was assessed by IFNgamma-producing spot-forming-units (SFU) by ELISPOT assay and flow cytometry.

High-resolution Magnetic Resonance Imaging visualizes intracranial large artery involvement in Giant Cell Arteritis.

Objective: Giant Cell arteritis (GCA) is a large vessel vasculitis, typically involving the aorta and its branches with predilection for the scalp arteries. Intracranial involvement is still part of ongoing research. We assess inflammation of the intracranial arteries on 3D-black-blood magnetic resonance imaging (3D-CS-BB-MRI) in patients with GCA and age-matched controls.

Case Report: Effectiveness of secukinumab in systemic sclerosis with early skin progress after autologous hematopoietic stem cell transplantation and end-stage kidney disease.

Autologous hematopoietic stem cell transplantation (aHSCT) represents an effective treatment option in patients with severe forms of systemic sclerosis (SSc) by resetting the immune system. Nevertheless, secondary autoimmune disorders and progressive disease after aHSCT might necessitate renewed immunosuppressive treatments. This is particularly challenging when organ dysfunction, i.

Real-World Effectiveness and Safety of SDZ ETN, an Etanercept Biosimilar, in Patients with Rheumatic Diseases: Final Results from Multi-Country COMPACT Study.

Introduction: COMPACT, a non-interventional study, evaluated the persistence, effectiveness, safety and patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA), axial-spondyloarthritis (axSpA) or psoriatic arthritis (PsA) treated with SDZ ETN (etanercept [ETN] biosimilar) in Europe and Canada.

Methods: Patients (aged ≥ 18 years) who have been treated with SDZ ETN were categorised on the basis of prior treatment status (groups A-D): patients in clinical remission or with low disease activity under treatment with reference ETN or biosimilar ETN and switched to SDZ ETN; patients who received non-ETN targeted therapies and switched to SDZ ETN; biologic-naïve patients who started SDZ ETN after conventional therapy failure; or disease-modifying anti-rheumatic drug (DMARD)-naïve patients with RA considered suitable for treatment initiation with a biologic and started on treatment with SDZ ETN. The primary endpoint was drug persistence, defined as time from study enrolment until discontinuation of SDZ ETN treatment.

PET-Derived Increased Inflammation in Large Vessels is linked to Relapse-Free Survival in Patients with Giant Cell Arteritis.

Background:  Despite anti-inflammatory treatment, patients with giant cell arteritis (GCA) experience relapse. We aimed to determine respective relapse predictors focusing on [F]fluorodeoxyglucose ([F]FDG)-PET-based parameters.

Material And Methods:  21 therapy-naïve GCA patients received [F]FDG-PET/CT.

Impact of Systemic Sclerosis-Associated Interstitial Lung Disease With and Without Pulmonary Hypertension on Survival: A Large Cohort Study of the German Network for Systemic Sclerosis.

Background: Pulmonary involvement is the leading cause of death in systemic sclerosis (SSc) and may manifest as interstitial lung disease (ILD), pulmonary arterial hypertension (PAH), or in combination of both (ILD with pulmonary hypertension [ILD-PH]). The aim of this analysis was to determine prevalence, clinical characteristics, and survival of these different forms within the registry of the German Network for Systemic Sclerosis.

Research Question: Does SSc-associated ILD-PH or ILD without PH affect survival differently, and are there any risk factors that have an additional impact?

Study Design And Methods: Clinical data of 5,831 patients with SSc were collected in the German Network for Systemic Sclerosis registry.

Mesenchymal stem cells modulate IL-17 and IL-9 production induced by Th17-inducing cytokine conditions in autoimmune arthritis: an explorative analysis.

Background: The importance of proinflammatory T-cells and their cytokine production in patients with autoimmune arthritis has been widely described. Due to their immunomodulatory properties, mesenchymal stem cells (MSCs) have come into focus as a potential therapeutic concept. The aim of this study was to investigate the influence of MSCs on the phenotype, cytokine profile, and functionality of naive and non-naive CD4 T-cells from healthy donors (HD) and patients with autoimmune arthritis under Th17-cytokine polarizing conditions in an explorative way using a transwell system prohibiting any cell-cell-contact.

Student-led clinics and ePROs to accelerate diagnosis and treatment of patients with axial spondyloarthritis: results from a prospective pilot study.

We aimed to investigate (1) student-led clinics and (2) electronic patient-reported outcomes (ePROs) to accelerate diagnosis and treatment of patients with axial spondyloarthritis (axSpA). Patients with suspected axSpA completed an initial student-led clinic visit (T-1) prior to their planned actual rheumatologist visit (T0). Acceleration of patient appointment and NSAID therapy start, availability of diagnostic findings, and treatment response at T0 were evaluated.

Patient-reported outcomes provide evidence for increased depressive symptoms and increased mental impairment in giant cell arteritis.

Objectives: The spectrum of giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) represents highly inflammatory rheumatic diseases. Patients mostly report severe physical impairment. Possible consequences for mental health have been scarcely studied.

Stepwise asynchronous telehealth assessment of patients with suspected axial spondyloarthritis: results from a pilot study.

Patients with axial spondyloarthritis (axSpA) suffer from one of the longest diagnostic delays among all rheumatic diseases. Telemedicine (TM) may reduce this diagnostic delay by providing easy access to care. Diagnostic rheumatology telehealth studies are scarce and largely limited to traditional synchronous approaches such as resource-intensive video and telephone consultations.
