Abatacept inhibits inflammation and onset of rheumatoid arthritis in individuals at high risk (ARIAA): a randomised, international, multicentre, double-blind, placebo-controlled trial.

BACKGROUND: Individuals with anti-citrullinated protein antibodies (ACPAs) and subclinical inflammatory changes in joints are at high risk of developing rheumatoid arthritis. Treatment strategies to intercept this pre-stage clinical disease remain to be developed. We aimed to assess whether 6-month treatment with abatacept improves inflammation in preclinical rheumatoid arthritis. METHODS: The abatacept reversing subclinical inflammation as measured by MRI in ACPA positive arthralgia (ARIAA) study is a randomised, international, multicentre, double-blind, placebo-controlled trial done in 14 hospitals and community centres across Europe (11 in Germany, two in Spain, and one in the Czech Republic). Adults (aged ≥18 years) with ACPA positivity, joint pain (but no swelling), and signs of osteitis, synovitis, or tenosynovitis in hand MRI were randomly assigned (1:1) to weekly subcutaneous abatacept 125 mg or placebo for 6 months followed by a double-blind, drug-free, observation phase for 12 months. The primary outcome was the proportion of participants with any reduction in inflammatory MRI lesions at 6 months. The primary efficacy analysis was done in the modified intention-to-treat population, which included participants who were randomly assigned and received study medication. Safety analyses were conducted in participants who received the study medication and had at least one post-baseline observation. The study was registered with the EUDRA-CT (2014-000555-93). FINDINGS: Between Nov 6, 2014, and June 15, 2021, 139 participants were screened. Of 100 participants, 50 were randomly assigned to abatacept 125 mg and 50 to placebo. Two participants (one from each group) were excluded due to administration failure or refusing treatment; thus, 98 were included in the modified intention-to-treat population. 70 (71%) of 98 participants were female and 28 (29%) of 98 were male. At 6 months, 28 (57%) of 49 participants in the abatacept group and 15 (31%) of 49 participants in the placebo group showed improvement in MRI subclinical inflammation (absolute difference 26·5%, 95% CI 5·9-45·6; p=0·014). Four (8%) of 49 participants in the abatacept group and 17 (35%) of 49 participants in the placebo group developed rheumatoid arthritis (hazard ratio [HR] 0·14 [0·04-0·47]; p=0·0016). Improvement of MRI inflammation (25 [51%] of 49 participants in the abatacept group, 12 [24%] of 49 in the placebo group; p=0·012) and progression to rheumatoid arthritis (17 [35%] of 49, 28 [57%] of 49; HR 0·14 [0·04-0·47]; p=0·018) remained significantly different between the two groups after 18 months, 12 months after the end of the intervention. There were 12 serious adverse events in 11 participants (four [8%] of 48 in the abatacept group and 7 [14%] of 49 in the placebo group). No deaths occurred during the study. INTERPRETATION: 6-month treatment with abatacept decreases MRI inflammation, clinical symptoms, and risk of rheumatoid arthritis development in participants at high risk. The effects of the intervention persist through a 1-year drug-free observation phase. FUNDING: Innovative Medicine Initiative.

[Pulmonary involvement in idiopathic inflammatory myopathies]. / Pulmonale Beteiligung bei idiopathischen inflammatorischen Myopathien.

Idiopathic inflammatory myopathies are rare systemic diseases with different types of pulmonary manifestations depending on the underlying aetiology; here, interstitial lung diseases (ILD) are the most frequently found patterns depending on the underlying disorder. There is a lack of sufficient prospective studies on this heterogeneous group of patients, particularly in case of ILD being involved. The diagnosis is based upon guideline recommendations for ILD and requires a multidisciplinary discussion within a team with specific expertise in this field. Myositis specific antibodies and myositis associated antibodies form an essential part of the diagnostic tools and may also be associated with a certain phenotype or disease progression. Anti-t-RNA-synthetase antibodies (Anti-ARS) and anti-melanoma differentiation-associated gene 5 antibodies (MDA5) play an important clinical role for treatment the estimation of response and prognosis. The most common ILD patterns are nonspecific interstitial pneumonia (NSIP) and organising pneumonia (OP) or a mixed pattern of both. Treatment is based on systemic steroids and early initiation of other immunosuppressant drugs. Evidence for this is, however, sparse, since most of the studies having investigated treatment modalities are of retrospective nature, even though some new prospective data may be useful for the establishment of treatment pathways in the future.

Humoral immunogenicity of COVID-19 vaccines in patients with inflammatory rheumatic diseases under treatment with Rituximab: a case-control study (COVID-19VacRTX).

OBJECTIVES: Patients with inflammatory rheumatic diseases (IRDs) treated with the anti-CD20 mAb rituximab (RTX) have been identified as high-risk for severe COVID-19 outcomes. Additionally, there is increased risk due to reduced humoral immune response, induced by therapeutic B cell depletion. This study sought to quantify humoral response after vaccination against SARS-CoV-2 in patients with IRD treated with RTX. It also sought to elucidate the influence of the time frame between the last RTX dose and the first vaccination, or the status of B cell depletion on antibody titre. METHODS: In this case-control study, patients with IRDs previously treated with RTX were examined for humoral immune response after completing the first series of vaccinations with approved vaccines [BNT162b2 (Biontech/Pfizer), RNA-1273 (Moderna), AZD1222 (AstraZeneca/Oxford), Ad26.COV2.S (Janssen/Johnson & Johnson)]. Antibody levels were quantified using the Euroimmun Anti-SARS-CoV-2 QuantiVac ELISA (EI-S1-IgG-quant). Blood samples were taken just before the next infusion with RTX after the vaccination. The interval between the last RTX infusion and the first vaccination against SARS-CoV-2 and other possible factors influencing the antibody levels were evaluated. RESULTS: A total of 102 patients were included. Of these, 65 (64%) showed a negative antibody level (<24 IU (international unit)/ml) after the vaccination. The comparative univariate analysis of the antibody levels achieved a significant result (P = 0.0008) for the time between the last RTX infusion and first vaccination against SARS-CoV-2. No CD19+ peripheral B-cells could be detected in 73 of the patients (72%). CONCLUSION: The study confirms the negative impact of RTX on antibody level after vaccination against SARS-CoV-2. A clear relationship exists between the antibody titre and the interval between the last RTX infusion and the first vaccination, the number of peripheral B-cells, and immunoglobulin quantity. Improved understanding of the effect of these parameters can help guide synchronization of vaccination in relation to the RTX therapy regimen.

[Rheumatologic inpatient treatment-more than a complex treatment : Data reflecting services and structures]. / Akutstationäre Rheumatologie ­ mehr als eine Komplexbehandlung : Versorgungsdaten und -strukturen.

To review and be prepared for upcoming reforms, data from the InEK (Institut für das Entgeltsystem im Krankenhaus, institute for remuneration in hospitals) data browser and the structured quality reports for inpatient rheumatologic treatment were evaluated. Rheumatologic treatment is very diversified, both in terms of diagnoses and structures. Different specializations can be identified. Rheumatologic complex treatment (RCT) is just one of these and is performed on average in just over 10% of cases. In 2020, cases for selected rheumatological diagnoses decreased by more than 20% compared to 2019. For RCT, the decline was even more pronounced with more than 30%. Evidence of higher disease severity could not be found in the available data. It remains to be seen whether the pre-Corona caseload will be regained in the coming years. In all, 146 organizational departments with more than 20 principal diagnoses of rheumatoid arthritis (RA) were identified in 2019. Forty-seven (32%) of these coded RCT more than ten times, and 29 (20%) more than one hundred times. All 23 departments with more than 300 principle diagnoses of RA are members of the Association of Rheumatological Acute Care Hospitals (Verband rheumatologischer Akutkliniken, VRA), 15 of which participated in the KOBRA quality project and carry the VRA seal of approval. Of the 116 internal medicine departments, only 55 (47%) use a specific specialty code for a rheumatology department according to Article 301 SGB V (social insurance code). Information on specialist staffing was partly contradictory. How many cases with inflammatory rheumatic diseases are treated in specialized departments cannot be answered with the available data. Nevertheless, the available data can be used for specialist, structural, and organizational developments in acute inpatient rheumatology.

[Publicity campaign rheuma2025 of the Union for Rheumatology]. / Öffentlichkeitskampagne "rheuma2025" des Bündnisses für Rheumatologie.

The publicity campaign "rheuma2025", initiated by the Union for Rheumatology, aims at improvement of patient-centered care. For this the number of positions for trainees in rheumatology needs to increase to a level which matches the public needs. Students in medical school must have even more interest for the discipline and they must be recruited. Regulatory constraints in the approval by the authorities for opening a private rheumatology practice must become much more flexible. The possibilities for in-patient acute care of patients in specialized hospitals have to be strengthened. Finally, the public image of rheumatology per se must be sharpened. To achieve these goals a homepage for the campaign was created ( https://rheuma2025.de ), which provides a toolkit of items for the public, for physicians and students. Various media channels for rheuma2025 were established with specific contents for each target group.

Tetraspanin CD9 affects HPV16 infection by modulating ADAM17 activity and the ERK signalling pathway.

Human papillomaviruses (HPV) are causative agents of various tumours such as cervical cancer. HPV binding to the cell surface of keratinocytes leads to virus endocytosis at tetraspanin enriched microdomains. Complex interactions of the capsid proteins with host proteins as well as ADAM17-dependent ERK1/2 signal transduction enable the entry platform assembly of the oncogenic HPV type 16. Here, we studied the importance of tetraspanin CD9, also known as TSPAN29, in HPV16 infection of different epithelial cells. We found that both overexpression and loss of the tetraspanin decreased infection rates in cells with low endogenous CD9 levels, while reduction of CD9 expression in keratinocytes that exhibit high-CD9 protein amounts, led to an increase of infection. Therefore, we concluded that low-CD9 supports infection. Moreover, we found that changes in CD9 amounts affect the shedding of the ADAM17 substrate transforming growth factor alpha (TGFα) and the downstream phosphorylation of ERK. These effects correlate with those on infection rates suggesting that a specific CD9 optimum promotes ADAM17 activity, ERK signalling and virus infection. Together, our findings implicate that CD9 regulates HPV16 infection through the modulation of ADAM17 sheddase activity.

Corrigendum: ErbB2/HER2 receptor tyrosine kinase regulates human papillomavirus promoter activity.

[This corrects the article DOI: 10.3389/fimmu.2024.1335302.].

ErbB2/HER2 receptor tyrosine kinase regulates human papillomavirus promoter activity.

Human papillomaviruses (HPVs) are a major cause of cancer. While surgical intervention remains effective for a majority of HPV-caused cancers, the urgent need for medical treatments targeting HPV-infected cells persists. The pivotal early genes E6 and E7, which are under the control of the viral genome's long control region (LCR), play a crucial role in infection and HPV-induced oncogenesis, as well as immune evasion. In this study, proteomic analysis of endosomes uncovered the co-internalization of ErbB2 receptor tyrosine kinase, also called HER2/neu, with HPV16 particles from the plasma membrane. Although ErbB2 overexpression has been associated with cervical cancer, its influence on HPV infection stages was previously unknown. Therefore, we investigated the role of ErbB2 in HPV infection, focusing on HPV16. Through siRNA-mediated knockdown and pharmacological inhibition studies, we found that HPV16 entry is independent of ErbB2. Instead, our signal transduction and promoter assays unveiled a concentration- and activation-dependent regulatory role of ErbB2 on the HPV16 LCR by supporting viral promoter activity. We also found that ErbB2's nuclear localization signal was not essential for LCR activity, but rather the cellular ErbB2 protein level and activation status that were inhibited by tucatinib and CP-724714. These ErbB2-specific tyrosine kinase inhibitors as well as ErbB2 depletion significantly influenced the downstream Akt and ERK signaling pathways and LCR activity. Experiments encompassing low-risk HPV11 and high-risk HPV18 LCRs uncovered, beyond HPV16, the importance of ErbB2 in the general regulation of the HPV early promoter. Expanding our investigation to directly assess the impact of ErbB2 on viral gene expression, quantitative analysis of E6 and E7 transcript levels in HPV16 and HPV18 transformed cell lines unveiled a noteworthy decrease in oncogene expression following ErbB2 depletion, concomitant with the downregulation of Akt and ERK signaling pathways. In light of these findings, we propose that ErbB2 holds promise as potential target for treating HPV infections and HPV-associated malignancies by silencing viral gene expression.

Clinical relevance of positively determined myositis antibodies in rheumatology: a retrospective monocentric analysis.

BACKGROUND: The increased availability of myositis autoantibodies represents new possibilities and challenges in clinical practice (Lundberg IE, Tjärnlund A, Bottai M, Werth VP, Pilkington C, de Visser M, et al. 2017 European League Against Rheumatism/American College of Rheumatology classification criteria for adult and juvenile idiopathic inflammatory myopathies and their major subgroups. Ann Rheum Dis. 2017;76:1955-64. https://doi.org/10.1136/annrheumdis-2017-211468 .). The aim of this study was to perform a retrospective data analysis of patient cases with positive myositis autoantibodies to analyse their significance in routine rheumatology practice. METHODS: A monocentric analysis of all the orders used to determine myositis autoantibodies from July 2019 to May 2022 in the Department of Rheumatology, Krankenhaus Porz am Rhein, Cologne, Germany, was carried out. RESULTS: In the defined time interval, a total of 71,597 laboratory values for the antibodies mentioned above were obtained. A total of 238 different positive autoantibodies ​​were detected in 209 patients. Idiopathic inflammatory myopathy was diagnosed in 37 patients (18%), and inflammatory rheumatic diseases other than idiopathic inflammatory myopathy were diagnosed in 90 patients (43%). No inflammatory rheumatic disease was diagnosed in 82 patients (39%). General clusters of clinical manifestations were observed. CONCLUSIONS: In our cohort, we were able to show that a relevant proportion of patients with positive myositis antibodies did not have idiopathic inflammatory myopathies or inflammatory rheumatic diseases. This finding indicates the importance of myositis autoantibodies in this group of patients. However, further studies on the course of symptoms and examination results in patients without inflammatory rheumatic diseases and with positive myositis antibodies are necessary.

Effect of Lifestyle Counselling via a Mobile Application on Disease Activity Control in Inflammatory Arthritis: A Single-Blinded, Randomized Controlled Study.

BACKGROUND: Mobile applications (apps) are a resource for information on lifestyle and nutrition which are associated to improved outcomes in inflammatory arthritis. OBJECTIVE: The aim of this study was to explore whether targeted lifestyle counselling via an app improves disease activity in arthritis patients. METHODS: Patients with rheumatoid arthritis (RA), spondyloarthritis (SpA), psoriatic arthritis (PsA) were randomized to 12 weeks of lifestyle counselling via an app (Mida, Midaia GmbH, Germany) pertaining to a healthy Mediterranean Diet, physical activity, and mental health. Disease activity was measured with specific instruments by a blinded physician and categorized (remission, low, moderate, high). Dietary adherence was assessed by the Mediterranean Diet Adherence Screener (MEDAS). Mixed effects logistic regression adjusted to baseline disease activity, age, and sex were calculated. RESULTS: Of 158 patients included (73% female, 53.3 ± 11.7 years), 74 were in the active counselling group (ACG). All showed improvement in low disease activity or remission. ACG patients had an odds ratio (OR) of 2.8 (95%-CI 1.1-7.2, p = 0.035), while OR in the control group was not significant OR = 2.1 (0.9-5.0, p = 0.097). The control group was less likely to reach a MEDAS >= 4 (OR = 0.16 (0.03-0.77), p = 0.02), while this was not seen in the ACG (OR = 0.54 (0.06-4.63), p = 0.6). Patients in the ACG showed a tendency towards improved adhesion to a Mediterranean Diet (MEDAS) (ß = 0.35 (-0.05-0.74), p = 0.086). This tendency was not observed in the control group (ß = 0.09 (-0.29-0.46), p = 0.64). CONCLUSIONS: Individualized lifestyle and dietary counselling via app may help to improve disease control in inflammatory arthritis patients.

The US7 score is sensitive to change in a large cohort of patients with rheumatoid arthritis over 12 months of therapy.

PURPOSE: To determine the sensitivity to change of the US7 score among RA patients under various therapies and to analyze the effect of each therapeutic option over 1 year. To estimate predictors for development of destructive bone changes. METHODS: Musculoskeletal ultrasound (US7 score), DAS28, CRP and ESR were performed in 432 RA patients at baseline and after 3, 6 and 12 months. The cohort was divided into four sub-groups: first-line DMARDs (Group 1; 27.3%), therapy switch: DMARDs to second DMARDs (Group 2; 25.0%), first-line biologic after DMARDs therapy (Group 3; 35.4%) and therapy change from biologic to second biologic (Group 4; 12.3%). RESULTS: The US7 synovitis and tenosynovitis sum scores in grey-scale (GSUS) and power Doppler ultrasound (PDUS) as well as ESR, CRP decreased significantly (p<0.05) after 12 months in group 1 to 3. Group 1+2 also illustrated a significant change of DAS28 after 1 year (p<0.001). Only in Group 4, the US7 erosion sum score decreased significantly from 4.3 to 3.6 (p=0.008) after 1 year. Predictors capable of forecasting US erosions after one year were: higher score of US7 synovitis (p<0.001), of US7 erosions in GSUS (p<0.001), as well as of DAS28 (p<0.001) at baseline. CONCLUSIONS: The comparable developments of the US7 score with clinical and laboratory data illustrates its potential to reflect therapeutic response. Therefore, the novel US7 score is sensitive to change. Patients who switched from one biologic to another exhibited a significant decline in erosions after 12 months, while the erosions scores in the other groups were stable.

Evaluation of the novel ultrasound score for large joints in psoriatic arthritis and ankylosing spondylitis: six month experience in daily clinical practice.

BACKGROUND: To evaluate the utility of the recently introduced SOLAR score (sonography of large joints in Rheumatology), which has been validated in RA patients, in a cohort of patients with Psoriatic Arthritis (PsA) and Ankylosing Spondylitis (AS) presenting with involvement of large peripheral joints. METHODS: The recently established SOLAR score has been designed to determine the degree of inflammation in the shoulder, the elbow, the hip and the knee joint in patients suffering from RA. Since large joints are frequently involved in PsA and AS, synovitis and synovial vascularity were scored semiquantitatively (grade 0-3) by grey scale (GSUS) and power Doppler ultrasound (PDUS) utilizing the validated scoring system. Each joint was scanned from different angles, the knee joint for example was divided into four areas to score for synovitis: the suprapatellar longitudinal, the medial longitudinal, the lateral longitudinal, and the posterior region. Each area was scored from 0-3, so a maximum score of 12 could be achieved. PsA and AS patients presenting with peripheral joint disease involving large joints were examined at baseline, 3 and 6 months after initiation of local or systemic therapy (DMARDs/Biologics). For evaluation of the inflammatory status, the erythrocyte sedimentation rate (ESR) was determined. RESULTS: A cohort of 126 patients were enclosed, and 83 of these were followed for 6 months. At baseline before modification of the therapy, patients received DMARDs (n = 83), DMARDs plus biologics (n = 30), or biologic monotherapy (n = 29). Following intervention, all US scores demonstrated a marked improvement. The GSUS and the PDUS scores for all joint areas, except the PDUS score of the hip, exhibited a significant improvement (p < 0.05), while the GSUS of the knee showed even a highly significant (p < 0.001) change. The ESR displayed a significant decrease from 27 to 19 mm (p < 0.002) representing good treatment response. CONCLUSION: The SOLAR score, which has been recently introduced for RA patients, is a very suitable instrument for the qualitative and quantitative evaluation of large joint involvement in PsA and AS patients and allows for treatment monitoring.

[Treatment alternatives for amyopathic MDA5-positive dermatomyositis]. / Therapiealternativen bei amyopathischer MDA5-positiver Dermatomyositis.

We report a case of an atypical course of therapy in amyopathic MDA5-antibody-positive dermatomyositis with interstitial lung disease. Due to the poor prognosis, early therapy with cyclophosphamide followed by rituximab was carried out initially in addition to the administration of prednisolone. Due to therapy failure, treatment was switched to mycophenolate mofetil. This showed a surprisingly rapid positive course in terms of interstitial lung disease, skin manifestation, and general disease activity.

Sensitivity and specificity of ultrasonography and low-field magnetic resonance imaging for diagnosing arthritis.

OBJECTIVES: To evaluate the value of grey-scale ultrasonography (US) including power Doppler ultrasonography (PDUS) and low-field magnetic resonance imaging (MRI) for the diagnosis of arthritis in a diagnostic phase III study. METHODS: Fifty consecutive patients with suspected arthritis were included in the study. Following a standardised protocol, US of the carpus and the metacarpophalangeal (MCP) joints of the dominant hand was performed. Subsequently, low-field MRI was done using standard sequences, with contrast agent (Gadolinium DTPA) administered to 29 patients. RESULTS: In 32 out of 50 patients a clinical diagnosis of arthritis was established. In grey-scale ultrasonography including PDUS, sensitivity and specificity were determined as 0.94 and 0.5, respectively, for synovitis (effusion and hypertrophy), 0.72 and 0.94, respectively, for Doppler signals, and 0.38 and 1.0, respectively, for bone erosions. In low-field MRI, sensitivity and specificity values were 0.77 and 0.75, respectively, for synovitis (when using contrast agent), 0.48 and 0.78, respectively, for bone marrow oedema, and 0.58 and 0.83, respectively, for bone erosion. CONCLUSIONS: Both grey-scale ultrasonography including PDUS and low-field MRI are suitable imaging methods for diagnosing arthritis at an early stage. However, PDUS displays a higher specificity and almost the same sensitivity as compared to contrast-enhanced MRI, while being a much simpler and less costly procedure.

HPV16 Induces Formation of Virus-p62-PML Hybrid Bodies to Enable Infection.

Human papillomaviruses (HPVs) inflict a significant burden on the human population. The clinical manifestations caused by high-risk HPV types are cancers at anogenital sites, including cervical cancer, as well as head and neck cancers. Host cell defense mechanisms such as autophagy are initiated upon HPV entry. At the same time, the virus modulates cellular antiviral processes and structures such as promyelocytic leukemia nuclear bodies (PML NBs) to enable infection. Here, we uncover the autophagy adaptor p62, also known as p62/sequestosome-1, as a novel proviral factor in infections by the high-risk HPV type 16 (HPV16). Proteomics, imaging and interaction studies of HPV16 pseudovirus-treated HeLa cells display that p62 is recruited to virus-filled endosomes, interacts with incoming capsids, and accompanies the virus to PML NBs, the sites of viral transcription and replication. Cellular depletion of p62 significantly decreased the delivery of HPV16 viral DNA to PML NBs and HPV16 infection rate. Moreover, the absence of p62 leads to an increase in the targeting of viral components to autophagic structures and enhanced degradation of the viral capsid protein L2. The proviral role of p62 and formation of virus-p62-PML hybrid bodies have also been observed in human primary keratinocytes, the HPV target cells. Together, these findings suggest the previously unrecognized virus-induced formation of p62-PML hybrid bodies as a viral mechanism to subvert the cellular antiviral defense, thus enabling viral gene expression.

HPV16 Entry into Epithelial Cells: Running a Gauntlet.

During initial infection, human papillomaviruses (HPV) take an unusual trafficking pathway through their host cell. It begins with a long period on the cell surface, during which the capsid is primed and a virus entry platform is formed. A specific type of clathrin-independent endocytosis and subsequent retrograde trafficking to the trans-Golgi network follow this. Cellular reorganization processes, which take place during mitosis, enable further virus transport and the establishment of infection while evading intrinsic cellular immune defenses. First, the fragmentation of the Golgi allows the release of membrane-encased virions, which are partially protected from cytoplasmic restriction factors. Second, the nuclear envelope breakdown opens the gate for these virus-vesicles to the cell nucleus. Third, the dis- and re-assembly of the PML nuclear bodies leads to the formation of modified virus-associated PML subnuclear structures, enabling viral transcription and replication. While remnants of the major capsid protein L1 and the viral DNA remain in a transport vesicle, the viral capsid protein L2 plays a crucial role during virus entry, as it adopts a membrane-spanning conformation for interaction with various cellular proteins to establish a successful infection. In this review, we follow the oncogenic HPV type 16 during its long journey into the nucleus, and contrast pro- and antiviral processes.
