Background: Day care units are an essential part of psychiatric treatment in Germany. In rheumatology they are also regularly used. Axial spondylarthritis (axSpA) is an inflammatory rheumatic disease that causes pain, diminished quality of life, limitations in activities of daily living and ability to work, especially if insufficiently treated. The multimodal rheumatologic complex treatment with at least 14 days of inpatient care is an established tool to control exacerbated disease activity. The feasibility and effect of an equivalent treatment in a day care setting has not yet been evaluated., Methods: The effect of a therapy in a day care unit comparable to the inpatient multimodal rheumatologic complex treatment was investigated using clinically established patient reported outcomes (NAS pain, FFbH, BASDAI, BASFI)., Results: Selected subgroups of axSpA patients can routinely and effectively be treated in day care units. Intensified multimodal as well as nonintensified treatment forms lead to reduced disease activity. Additionally, compared to nonintensified treatment, the intensified multimodal treatment approach leads to significantly reduced pain, and disease-related and functional limitations in daily life., Conclusion: If available, treatment in a day care unit can complement the established inpatient treatment modalities in selected axSpA patients. In cases with high disease activity and suffering, intensified multimodal treatment should be preferred due to better outcomes., (© 2023.

Objectives: To investigate, whether inflammatory rheumatic diseases (IRD) inpatients are at higher risk to develop a severe course of SARS-CoV-2 infections compared to the general population, data from the German COVID-19 registry for IRD patients and data from the Lean European Survey on SARS-CoV-2 (LEOSS) infected patients covering inpatients from the general population with SARS-CoV-2 infections were compared., Methods: 4310 (LEOSS registry) and 1139 cases (IRD registry) were collected in general. Data were matched for age and gender. From both registries, 732 matched inpatients (LEOSS registry: n = 366 and IRD registry: n = 366) were included for analyses in total., Results: Regarding the COVID-19 associated lethality, no significant difference between both registries was observed. Age > 65°years, chronic obstructive pulmonary disease, diabetes mellitus, rheumatoid arthritis, spondyloarthritis and the use of rituximab were associated with more severe courses of COVID-19. Female gender and the use of tumor necrosis factor-alpha inhibitors (TNF-I) were associated with a better outcome of COVID-19., Conclusion: Inflammatory rheumatic diseases (IRD) patients have the same risk factors for severe COVID-19 regarding comorbidities compared to the general population without any immune-mediated disease or immunomodulation. The use of rituximab was associated with an increased risk for severe COVID-19. On the other hand, the use of TNF-I was associated with less severe COVID-19 compared to the general population, which might indicate a protective effect of TNF-I against severe COVID-19 disease., Competing Interests: TW was employed by company Biocontrol Jena.

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. Kaplan-Meier estimates were used to compare overall survival in patients with SSc-associated ILD-PH and ILD without PH with patients without pulmonary involvement and those with PAH. The Cox proportional hazard model was used to analyze the influence of pulmonary involvement and other potential predictors on patient survival., Results: Clinical data of 3,257 patients with a mean follow-up time of 3.45 ± 1.63 years have been included in our analysis. At baseline, ILD was present in 34.5%, whereas PH without ILD had a lower prevalence with 4.5%. At the end of follow-up, 47.6% of patients with SSc had ILD, 15.2% had ILD-PH, and 6.5% had PAH. ILD was more frequent in the diffuse cutaneous form (57.3%), whereas PAH did not differ significantly between SSc subtypes. Significant differences in baseline characteristics between PAH vs ILD-PH vs ILD without PH were found for age at diagnosis, sex, SSc subsets, antibody status, FVC, diffusing capacity of the lung for carbon monoxide, and therapy. Overall survival at 5 years was 96.4% for patients without pulmonary involvement and differed significantly between patients with ILD without PH, PAH, and being worst in patients with ILD-PH. Female sex (hazard ratio [HR], 0.3), higher BMI (HR, 0.9), and higher diffusing capacity of the lung for carbon monoxide values (HR, 0.98) were associated with a lower mortality risk., Interpretation: ILD is the most prevalent pulmonary involvement in SSc, whereas the combination of ILD and PH is associated with the most detrimental survival., Competing Interests: Financial/Nonfinancial Disclosures The authors have reported to CHEST the following: M.
