The Joint Vasculitis Registry in German-speaking countries (GeVas): subgroup analysis of 266 AAV patients.

OBJECTIVES: Prospective long-term observational data on the disease course of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) were missing in Germany to date. Therefore, the Joint Vasculitis Registry in German-speaking countries (GeVas) has been established to follow the course of patients with AAV. The aim of this study is to present baseline data of patients with newly diagnosed and relapsing AAV enrolled in the GeVas registry. METHODS: GeVas is a prospective, web-based, multicentre, clinician-driven registry for the documentation of organ manifestations, damage, long-term outcomes, and therapy regimens in various types of vasculitis. Recruitment started in June 2019. RESULTS: Between June 2019 and October 2022, 266 patients with AAV were included in the GeVas registry: 173 (65%) with new-onset and 93 (35%) with relapsing AAV. One hundred and sixty-two (61%) patients were classified as granulomatosis with polyangiitis (GPA), 66 (25%) as microscopic polyangiitis (MPA), 36 (13%) as eosinophilic granulomatosis with polyangiitis (EGPA), and 2 (1%) as renal limited AAV. The median age was 59 years (51-70 years, IQR), 130 (51%) patients were female. Most patients were ANCA positive (177; 67%) and affected by general symptoms, pulmonary, ear nose throat (ENT), renal and neurological involvement. For induction of remission, the majority of patients received glucocorticoids (247, 93%) in combination with either rituximab (118, 45%) or cyclophosphamide (112, 42%). CONCLUSIONS: Demographic characteristics are comparable to those in other European countries. Differences were found regarding ANCA status, frequencies of organ manifestations, and therapeutic regimens. The GeVas registry will allow longitudinal observations and prospective outcome measures in AAV.

The Joint Vasculitis Registry in German-speaking countries (GeVas): subgroup analysis of 195 GCA patients.

OBJECTIVES: Giant cell arteritis (GCA) is one of the most common forms of vasculitis. There is an abundance of studies which are conducted in a randomised controlled trial setting but limited with respect to cohort size and follow-up time. GeVas is the first large-scale registry for vasculitides in German-speaking countries that enables to evaluate this rare disease. Herein we focus on the subgroup of GCA patients including follow-up data up to one year. METHODS: GeVas is a prospective, web-based, multicentre registry for the documentation of organ manifestations, outcomes, and therapy regimens in vasculitides. Recruitment started in June 2019. By April 2023, 15 centres were initiated and have started to enrol patients. RESULTS: After 4 years, 195 GCA-patients were included in the registry, of which 64% were female and 36% were male. The average age was 76 years at the time of recruitment (IQR=69-82). Seventy-nine percent were included in the registry because of a newly diagnosed GCA and 21% because of a relapse. At the first assessment most of the patients (89%) described general symptoms. Thirty-one percent stated ocular symptoms. Cranial symptoms were documented in 78% of the cases. All patients were documented with immunosuppressive treatment at start, of whom 95% received prednisolone, 16% cyclophosphamide, 20% methotrexate, and 48% tocilizumab. After three months 62% and after one year 91% of the patients achieved remission. CONCLUSIONS: Regarding demographics, clinical manifestations and diagnostics, our study showed a similar composition compared to other studies. However, our data differed in terms of treatment regimens.

Multiple Abscess Collections: Antibiotics or Steroids?

Aseptic abscess syndrome (AAS) is a medical rarity. The combination of multiple abscess collections in different organs, negative microbiological studies, and the association with an inflammatory bowel disease is highly suggestive for an AAS. The AAS is an acute neutrophilic dermatosis, so "generalized pyoderma gangraenosum" or "generalized bullous sweet syndrome" might be used synonymously. It is important to note that the diagnosis of an AAS can be made only after careful exclusion of an infectious disease. Of interest, despite the severity of the inflammation, patients with AAS are commonly hemodynamically stable. To date, no studies have investigated the optimal regimen, dose, and duration of therapy. Corticosteroids are the cornerstone of immunosuppression during the acute phase. After the induction phase, therapy might be switched to anakinra or infliximab.

[Secondary vasculitides]. / Sekundäre Vaskulitiden.

Vasculitides that occur in association with underlying primary diseases are called secondary vasculitides. In the diverse differential diagnostics of vasculitides, a large variety of secondary vasculitides have to be considered. Secondary vasculitides cover the full spectrum of vasculitides, presenting in manifold clinical manifestations. This article provides an overview of systemic diseases and etiological factors, such as infections, drugs, and malignancies, which can be associated with vasculitides. The possible associations with infectious agents are too numerous to be comprehensively covered and are discussed in an exemplary fashion and with a western European focus. Especially in atypical and refractory disease courses, a secondary vasculitis should be considered. In light of the diversity of differential diagnoses and the particular challenges posed by secondary vasculitides, interdisciplinary collaboration is the key for an accurate and early diagnosis as well as for successful treatment management. Treatment of the primary disease should always be prioritized and, if a drug-induced vasculitis is suspected, immediate cessation of the culprit drug is mandatory.

[Immunoglobulin A vasculitis (IgAV)]. / Immunglobulin-A-Vaskulitis (IgAV).

IgA vasculitis (IgAV) is an immune complex-mediated vasculitis characterized by IgA1-dominant immune deposits in small vessels. It is the most common systemic vasculitis in childhood with a mostly uncomplicated and self-limiting course. Adults are less affected but the course is frequently more complicated and more frequently accompanied by renal involvement. IgAV characteristically manifests itself on the skin with palpable purpura and in joints, the kidneys and the gastrointestinal tract. In cases of incomplete or atypical symptoms a differential diagnostic work-up is required. A number of triggers have been suggested, especially infections and drugs. Disease management is tailored to organ manifestations and the severity of the symptoms. For children, optimized supportive care and targeted symptom relief are usually sufficient. Management of renal and gastrointestinal manifestations follows recommendations for ANCA-associated vasculitis and IgA nephropathy. Treatment options include glucocorticoids and immunosuppressive agents with varying and mostly insufficient evidence.

Perioperative management of patients with inflammatory rheumatic diseases : Updated recommendations of the German Society for Rheumatology.

BACKGROUND: Prior to surgical interventions physicians and patients with inflammatory rheumatic diseases remain concerned about interrupting or continuing anti-inflammatory medication. For this reason, the German Society for Rheumatology has updated its recommendations from 2014. METHODS: After a systematic literature search including publications up to 31 August 2021, the recommendations on the use of of glucocorticoids, conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and biologics (bDMARDs) were revised and recommendations on newer drugs and targeted synthetic (ts)DMARDs were added. RESULTS: The glucocorticoid dose should be reduced to as low as possible 2-3 months before elective surgery (in any case <10 mg/day) but should be kept stable 1-2 weeks before and on the day of surgery. In many cases csDMARDs can be continued, exceptions being a reduction of high methotrexate doses to ≤15 mg/week and wash-out of leflunomide if there is a high risk of infection. Azathioprine, mycophenolate and ciclosporin should be paused 1-2 days prior to surgery. Under bDMARDs surgery can be scheduled for the end of each treatment interval. For major interventions Janus kinase (JAK) inhibitors should be paused for 3-4 days. Apremilast can be continued. If interruption is necessary, treatment should be restarted as soon as possible for all substances, depending on wound healing. CONCLUSION: Whether bDMARDs increase the perioperative risk of infection and the benefits and risks of discontinuation remain unclear based on the currently available evidence. To minimize the risk of a disease relapse under longer treatment pauses, in the updated recommendations the perioperative interruption of bDMARDs was reduced from at least two half-lives to one treatment interval.

[Neoehrlichiosis as a cause of feaver of unknown origin]. / Neoehrlichiose als Ursache eines Fiebers unklarer Genese.

Establishing a diagnosis in cases of fever of unknown origin (FUO) in immunocompromised patients can be difficult. In 25-35% infectious diseases are the underlying cause. This article reports the case of a 74-year-old woman with a 5-month history of fever. Through open biopsy of the femoral shaft and microbiological analysis, a diagnosis of neoehrlichiosis could be established. After initiation of treatment with doxycycline, the symptoms quickly resolved resulting in a complete recovery.

The Joint Vasculitis Registry in German-speaking countries (GeVas) - a prospective, multicenter registry for the follow-up of long-term outcomes in vasculitis.

BACKGROUND: Vasculitides comprise a group of rare diseases which affect less than 5 in 10.000 individuals. Most types of vasculitis can become organ- and life-threatening and are characterized by chronicity, high morbidity and relapses, altogether resulting in significant morbidity and mortality. Previous studies have been either monocentric or mainly retrospective - studies with a prospective design mostly consisted of rather small cohorts of 100 to 200 patients. The aim of the Joint Vasculitis Registry in German-speaking countries (GeVas) is to record all patients who have been recently diagnosed with vasculitis or who have changed their treatment due to a relapse (inception cohort). In GeVas, data are collected prospectively in a multicenter design in Germany, Austria and Switzerland. By this approach, courses of vasculitis and their outcomes can be monitored over an extended period. METHODS: GeVas is a prospective, web-based, multicenter, clinician-driven registry for the documentation of organ manifestations, damage, long-term progress and other outcomes of various types of vasculitis. The registry started recruiting in June 2019. As of October 2020, 14 centers have been initiated and started recruiting patients in Germany. Involvement of sites in Austria and the German-speaking counties of Switzerland is scheduled in the near future. DISCUSSION: In June 2019, we successfully established a prospective multicenter vasculitis registry being the first of its kind in German-speaking countries. The participating centers are currently recruiting, and systematic analysis of long-term vasculitis outcomes is expected in the ensuing period. TRIAL REGISTRATION: German Clinical Trials Register (Deutsches Register Klinischer Studien): DRKS00011866 . Registered 10 May 2019.

[Current state of vaccination against SARS-CoV-2]. / Aktueller Stand der Impfung gegen SARS-CoV-2.

On 21 December 2020 the European Medicines Agency (EMA) approved the mRNA vaccine BNT162b2 (Comirnaty®, BioNTech, Mainz, Germany; Pfizer, New York City, NY, USA) as the first vaccine against SARS-CoV­2 in the European Union and the second vaccine (Moderna®, Moderna, Cambridge, MA, USA) followed on 6 January 2021. Many more approvals will follow within a short period of time. With the availability of the vaccination many questions have arisen for patients as well as for physicians, which are addressed as up to date as possible in this hot topic article.

Updated recommendations of the German Society for Rheumatology for the care of patients with inflammatory rheumatic diseases in times of SARS-CoV-2-methodology, key messages and justifying information.

A few days after the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was declared a pandemic, the German Society for Rheumatology (DGRh) compiled the first group of recommendations for the care of patients with inflammatory rheumatic diseases in light of SARS-CoV-2/coronavirus disease 2019 (COVID-19). These first recommendations were based on an expert consensus and were largely non-evidence-based. Now that the first scientific data from registries, cross-sectional studies, case reports and case series are available, the DGRh has developed a timely update. This update is based on a literature search of publications available through 15 June 2020 and addresses preventive measures (such as hygiene measures or vaccinations) and the use of immunomodulatory/immunosuppressive drugs. Driven by the commitment to let patients benefit from these new evidence-based recommendations as quickly as possible, the DGRh published the update in German on its homepage and in the Zeitschrift für Rheumatologie immediately after completion. Here we report the key recommendations to make them available to the international community, provide the scientific methodology used to develop the recommendations, give additional thoughts and advice for the management of patients with rheumatic diseases during the COVID-19 pandemic and discuss our recommendations in the context of other international recommendations.

Granulomatosis with polyangiitis: mind the airway.

Granulomatosis with polyangiitis (GPA) is a potentially life-threatening disease that affects all ages. As the disease may be rapidly progressive, the undelayed recognition of its inflammatory activity is critical. This is especially important in central airway involvement, which contributes to morbidity and mortality.

A few days after the SARS-CoV-2 infection was declared a pandemic, the German Society for Rheumatology (DGRh) compiled first recommendations for the care of patients with inflammatory rheumatic diseases (IRD). These first recommendations were based on an expert consensus and were largely non-evidence-based. Now that the first scientific data from registers, cross-sectional studies, case reports and case series are available, the present update is intended to update the previous recommendations and to add new findings. The current recommendations are based on a literature search of publications available up to 15 June 2020 and address preventive measures (such as hygiene measures or vaccinations) and the use of immunomodulatory/immunosuppressive drugs. An important goal of the current recommendations is also to prevent harm to patients with IRD through unjustified restriction of care. The DGRh will continue to update its recommendations in the case of new aspects and will publish them as well as further information on the COVID-19 pandemic on its homepage ( www.dgrh.de ) in an ongoing process.
