Abstract
Abstract
Background
Small medical specialties may be more vulnerable to workforce shortage and the COVID-19 pandemic and this may directly impact in the provision of care for chronically-ill patients. This study aims to explore health workforce development and new needs, using rheumatology in Germany as a case study.
Methods
An explorative multi-methods approach was applied, combining health labour market assessment of rheumatology physicians (public statistics 2000-2019) and a questionnaire-based online survey conducted in early 2021 (n = 101 respondents; rheumatology physicians and residents). Main selected topics: work hours, workload, mental health issues, discrimination and sexual harassment experiences, impact of COVID-19. Descriptive statistical analysis was performed and qualitative content analysis for free-text information.
Results
Health labour market analysis showed that the numbers of rheumatologists increased markedly between 2000 and 2019 in the groups aged +50 years, but only 9% in younger groups under 50 years; since 2010 the group 40-50 years showed decreases. In 2019, the absolute number of rheumatologists working in healthcare after retirement-age exceeded those aged 40 and under. Survey data revealed a strong mismatch between actual and desired work hours for women and men. 81% rated their workload as high or very high; every sixth rheumatologist has suffered from stress or burnout syndromes at least once in the past. Experiences of gender discrimination and sexual harassment/violence were frequently reported, mostly by women. COVID-19 was an amplifier of stress with major stressors being digitalisation and increased demand for communication and patient education.
Conclusions
Decreasing health workforce capacities in German rheumatology combine with negative perceptions of work and workplace conditions, threatening both retention and service delivery.
Key messages
• Small medical specialties, like rheumatology, face severe shortage that threaten healthcare for chronically-ill patients and need greater attention.
• COVID-19 has reinforced rheumatologists’ workload and stressors, thus worsing mental health and retention.

Abstract
BackgroundSjögren’s Syndrome is well known for its characteristic sicca symptoms due to autoinflammatory destruction of the salivary and lacrymal glands, but neurological involvement is also common in this entity. Nevertheless, previously published smaller studies suggested distinct clinical features for Sjögren’s syndrome with and without neurological involvement, such as a more balanced gender distribution and lower IgG levels in patients with Sjögren‘ syndrome and neurological involvement1,2.ObjectivesWe therefore aimed to systematically assess clinical features of patients with Sjögren’s syndrome with and without neurological involvement, find relevant in-between group differences and hereby aid early detection of both patient groups in the clinical routine to facilitate further studies, potentially with new therapeutic approaches.MethodsWe retrospectively assessed patients with Sjögren’s syndrome treated at the neurological and rheumatological/ immunological departement of our university hospital between 05/2014 and 09/2021 for available laboratory and clinical data. The displayed data represent preliminary results of this ongoing study.Results405 patients, who fulfilled the current ACR/EULAR classification criteria for Sjögren’s syndrome3 were currently included in the study (median age 59years [IQR 50-70 years], median ESSDAI 10 [IQR 3-16]). 228 patients (56%) showed neurological involvement. They were significantly more often male (32% vs. 14%; p<0.001) and showed lower IgG serum levels (median 11 g/l [IQR 9-13 g/l] vs 12 g/l [IQR 10-16 g/l], p<0.01) in comparison to patients with Sjögren’s syndrome but without neurological involvement. However, presence of objective xerostomia, objective xerophthalmia, SSA(Ro)-antibody-positivity or sialadenits grade 3 or 4 (Chisholm and Mason) on salivary gland biopsy did not differ between the two groups.ConclusionPreliminary analysis of this ongoing study supports the hypothesis, that patients with Sjögren’s syndrome and neurological impairment might express a distinct clinical phenotype in comparison to patients with Sjögren’s syndrome but without neurological involvement.References[1]Sjögren’s syndrome should be considered in patients with motor neuropathy.

Abstract
BackgroundSystemic lupus erythematosus (SLE) is a chronic autoimmune disease with a variety of clinical manifestations [1] and has a profound effect on physical health [2]. Anxiety and depression are common symptoms of SLE which can have a significant impact on the quality of life [3].ObjectivesTo study whether or not the physical state of health relates to the extent of anxiety and depression in SLE patients.MethodsThe Physical Component Summary Score (PCS) was determined using the 36-Item Short Form Survey (SF-36) in a cohort of 146 SLE patients consecutively visiting our outpatient clinic. Two groups were compared: one group with low PCS<50 % (LPCS) and the comparison group with high PCS ≥50 % (HPCS). Patients with SLE who visited our Rheumatology clinic between March 2019 and December 2020 as part of a monocentric cross-sectional study completed additional standardized questionnaires: Hospital Anxiety and Depression Scale (HADS), Beck’s Depression Inventory (BDI II), Multidimensional Assessment of Fatigue (MAF), Functional questionnaire Hanover (FFbH) and the international questionnaire on physical activity in short form (IPAQ-SF). The data was analyzed with SPSS 27 (IBM, Armonk, NY, USA). The tests include bivariate and partial correlations. Significance tests were performed using non-parametric tests.ResultsIn total, 146 patients participated in the study. 14.4 % (n = 21) were male and the mean age was 48.6 ± 12.2 years. The mean state of physical health according to SF36 was 54.9 % ± 25.6 % in the examined cohort.There were 62 (42.5 %) patients with LPCS, of average age 50.4 ± 10.3 years and 84 (57.5 %) with HPCS, of average age 47.2 ± 13.3 years. The majority of patients in both groups were female (55/7, 88.7 % and 70/14, 83.3 %).A SLEDAI score > 2 was confirmed in 33.9 % (n = 21) of the patients with LPCS and in 25 % (n = 21) of patients with HPCS, the mean SLEDAI score did not significantly differ between LPCS and HPCS patients (2.4 versus 1.9, p = 0.261). Among patients with LPCS, 54.8 % (n = 34) presented low physical activity and 64.5 % reported functional impairment (FFbH < 80). More than half of LPCS-patients (53.2 %, n = 33) showed a low Mental Health summary score (MCS < 50 %) and over a third of them had moderate to severe depression (BDI II > 19, 38.7 %, n = 24) and indicated pathological anxiety (HADS > 10, 37.1 %, n = 23).Compared to the LPCS group, a smaller number of patients with HPCS had low physical activity (36.9 %, n = 31, p = 0.031) and the difference in mean weekly MET between the two groups was 2730 counts (p = 0.003). There was no impairment of functional capacity in patients with HPCS (FFbH mean Score 90.9 %, p < 0.001). In contrast to the LPCS group, only 17.9 % (n = 15) of the patients with HPCS showed MCS < 50 % (p < 0.001). Completely free of depressive symptoms were 65.5 % (n = 55) of the patients with HPCS and only 4 patients (4.8 %) reported moderate to severe depression (p < 0.001).Patients with LPCS reported fatigue (GFI > 20) more often than patients with HPCS (98.4 % versus 54.8, p < 0.001).ConclusionSLE patients with low physical health conditions have highly significant mental health impairment, particularly anxiety and depression. Physical functioning and limitations due to physical health should be considered and physical activity needs to be improved. Measurement of the PCS should be a routine tool in the overall assessment of the health conditions of SLE patients.References[1]Lisnevskaia, L., G. Murphy, and D.

Abstract
BackgroundSicca syndrome represents a heterogeneous group of conditions, including Sjögren syndrome, causing xerophthalmia and xerostomia.ObjectivesThis study characterizes in depth patients with Sicca syndrome and evaluates salivary gland ultrasound (SGUS) in this cohort.MethodsPrincipal component analysis and hierarchical clustering of clinical parameters, including ESSPRI, ESSDAI and laboratory data were performed on all referrals for assessment of Sicca symptoms between October 2018 and March 2021. SGUS and labial gland biopsies were compared across groups.Results583 patients were assessed. Objective dryness was confirmed in 73% of patients. Cluster analysis identified 3 groups with post-hoc analysis confirming distinct phenotypes: Somatic Group (283/583; 49%) with higher reported symptoms but limited objective dryness; Dry Without Autoimmune Features (DAFneg, 206/532; 35%) and Dry With Autoimmune Features (DAFpos, 94/532; 16%). DAFpos patients had highest autoantibody titres (SSA 240 vs 3.6 vs 3.8; p<0.001), most extra-glandular manifestations (p<0.001) and highest median SGUS Score (DAFpos: 8 [IQR 4-10] vs SG: 2 [1-4] vs DAFneg 4 [2-5]; p< 0.001). No tangible correlation primary Sjögren syndrome criteria was observed.ConclusionSGUS score correlated with a subset of Sjögren syndrome patients, identified in the DAFpos cluster. This study highlights heterogeneity within Sicca and indeed Sjögren syndrome, highlighting the need for further studies.References[1]Chisholm DM, Mason DK.

Abstract
Abstract
Background
Health workforce shortage in German rheumatology and its negative impact in healthcare are increasingly recognised. Health policy has increased staffing targets, but effective intervention strategies are lacking. This paper aims to systematically map the rheumatology workforce and to explore opportunities for intervention, thus contributing to better health workforce management.
Methods
The WHO National Health Workforce Accounts (NHWA) provided a conceptual framework for the mapping exercise. Four major sets of indicators were selected, comprising staffing levels, health labour market flows, skill-mix and education/training. Comparison of age-groups and time series was applied to explore trends. Public statistics and other secondary sources served the analysis, using descriptive methodology.
Results
Rheumatologists nearly doubled in absolute numbers since 2000, but this trend shows a problematic demographic bias. Between 2000 and 2019 numbers increased markedly in the groups aged +50 years, but only about 9% in younger groups under 50 years. Most alarming, since 2010 the group 40 to 50 years showed a reverse trend and strong decreases. In 2019, absolute numbers of rheumatologists working in healthcare after retirement-age exceeded those aged 40 and under. Since 2015 an expanding workforce trend overall flattened, but strongest in the hospital sector; annual inflows do not show relevant growths.
Conclusions
Health workforce assessment reveals negative demographic trends and decreasing appeal of the specialty especially to men, thus highlighting a need for more effective health workforce management. Intervention strategies should target innovation in resident training and task shifting and improve gender equality.
Key messages
Health workforce trends indicate that new health policy planning targets cannot be met with an available stock of rheumatologist. The WHO NHWA provide a useful toolbox to map health workforce trends and identify weaknesses and gaps.

Abstract
Background:Patients with primary Sjögren´s syndrome (pSS) suffer from pain, oral or ocular dryness and fatigue. Such symptoms can have a detrimental impact on health-related quality of life. The prevalence of mental health disorders in patients with pSS is considerably higher than in the general population [1]. Regular physical activity, such as nordic walking, improves aerobic capacity and may reduce reported fatigue [2]. According to current European League Against Rheumatism (EULAR) recommendations, management of pSS concomitant diseases should be evaluated in patients presenting with fatigue and pain, and severity scored using specific tools [3].Objectives:This study analyses the frequency and severity of depressive symptoms in patients with pSS and their relationship to fatigue and physical activity.Methods:In this monocentric, cross-sectional study, patients with pSS attending our Rheumatology clinic between January 2019 and March 2020 completed standardized questionnaires: Beck´s depression inventory second edition (BDI II) and the international physical activity questionnaire short form (IPAQ-SF). Data were analyzed using SPSS 26 (IBM, Armonk, NY, USA). The tests include bivariate and partial correlations and nonparametric Kruskal-Wallis-Test.Results:In total, 134 patients were included. The majority were female (117/134, 87.3 %), and the patients median age was 57 [21 – 85] years. Median duration of disease-related symptoms at inclusion was 56 months (range 0-388 months). Physical activity was low in 44. 8 % (n = 60), moderate in 32.1 % (n = 43), and high in 23.1 % (n = 31) of patients. Depressive symptoms of varying severity were identified in 76/134 (56.7%) of patients. Severe depression occurred in 10/76 (13.2%) and moderate depression in 14/76 (18.4%) patients. The remaining 52/76 (68.4%) patients had minimal or mild depression. Over two-thirds (67.7%) of patients reporting high physical activity showed no depression and no one with a high level of physical activity had severe depression. There was a clear association between the BDI II depression score and the level of physical activity (p = 0.003) regardless of age and illness duration. However, not all the symptoms assessed by BDI II had the same impact. From 21 items of the BDI II Inventory, symptoms such as loss of energy and fatigue were profoundly relevant, being reported by over 75 % of patients. The main depressive symptoms, which had a strong negative correlation with the level of physical activity were loss of energy (p < 0.001), sadness (p=0.018), inability to make decisions (p=0.007) and loss of pleasure (p=0.004). Somatic symptoms of decreased activation such as fatigue (p=0.026) and concentration difficulty (p=0.013) were also significant. The cognitive, self-negative symptoms were not associated with the level of physical activity.Conclusion:A negative correlation of physical activity with fatigue and depression in patients with pSS has been demonstrated. The somatic symptoms of decreased activation played a profound role in this association, while the cognitive self-negotiation symptoms were not influenced by physical activity in our patients. Such symptoms as fatigue and loss of energy could potentially be reduced by exercises and functional training and consequently decrease the level of depression. An intervention study in this regard would be recommended.References:[1]Cui, Y., et al., Anxiety and depression in primary Sjögren’s syndrome: a cross-sectional study.

Abstract
Background:Use of telemedicine in Germany has increased due to the COVID-19 lockdown. Between March and May 2020, government restrictions led to cancellation of routine outpatient appointments to limit viral spread and optimize resources.Objectives:This study assesses patient satisfaction of follow-up telemedicine appointments among patients known to be in disease remission, attending either secondary or tertiary care Rheumatology clinics. Appointments were conducted either by a rheumatologist or a qualified medical assistant for rheumatology (RFA). Additional data regarding perceived concerns arising from the COVID-19 pandemic as well as attitudes to vaccination were collected.Methods:Methods: Patients not requiring adjustment of their DMARDs at the two previous attendances were considered stable. At cancellation of the planned attendance, patients were offered participation in the study and provided verbal informed consent. Participants were randomized to a telemedicine appointment by either a physician or RFA. Telemedicine appointments consisted of a standardized patient interview, including assessment of disease activity (modified CDAI score), attitudes to vaccination as well as current vaccine status and concerns about COVID-19. Following participation, all patients received a pseudonymized postal questionnaire to evaluate appointment satisfaction (FAPI-Score).Results:In total 112/116 (96%) patients that were offered appointments, participated in the study (RA 50%, axSpA 30%, PsA 20%). Of these 88/112 (79%) returned their postal questionnaires. Overall patient satisfaction was excellent (mean 4.3/5 modified FAPI score) and did not differ between care setting or clinical status of the interviewer. RFAs conducted 19/112 (17%) of appointments, 6 (32%) of which required additional physician intervention. Change of DMARDs occurred in 19/112 (17%) appointments. Patients reporting a pain score ≥7 (VAS 1-10) were most dissatisfied with the telemedicine appointment (p=0.036). Concerns about COVID-19 correlated with disease activity: high disease activity (p = 0.031), presence of tender joints (p=0.001), high pain levels (p=0.009) correlated with concern of contracting COVID-19 or experiencing severe disease course. Only 38% of the patients had been vaccinated against pneumococci in the past 5 years and 54% had been vaccinated against influenza in 2019/2020.Conclusion:Telemedicine can contribute to patient care in stable patients. RFAs can also contribute to patient care especially for follow-up appointment when patients are in remission. Vaccination rates and motivation needs to be improved as influenza and pneumococcal vaccination is recommended to all patients with rheumatic diseases without contraindications.Disclosure of Interests:None declared

Abstract
BACKGROUND Patients with rheumatoid arthritis (RA) tend to be less physically active. Physical activity has been shown to have a positive impact on disease activity and quality of life and is recommended by the European League Against Rheumatism (EULAR) as an integral component of standard treatment. OBJECTIVE A cross-sectional analysis of RA patients was carried out assessing disease activity, functional capacity and fatigue associated with physical activity. MATERIAL AND METHODS Physical activity, functional capacity and the global fatigue index (GFI) were examined using standardized questionnaires: the international physical activity questionnaire short form (IPAQ-SF), the functional questionnaire Hannover (FFbH) and the multidimensional assessment of fatigue (MAF). The data were evaluated using SPSS 26 (IBM, Armonk, NY, USA). The level of significance was tested with bivariate and partial correlations and nonparametric tests. RESULTS In total 164 patients were included in the study. The majority of the patients were female (127/164; 77%) and the median age of the cohort was 58.3 years (range 21-86 years). The median duration of disease-related symptoms at inclusion was 169 months (range 0-713 months). Physical activity was low in 39%, moderate in 37% and high in 24%. Patients reporting higher levels of physical activity reported significantly lower GFI (p < 0.001), functional limitations (p < 0.001) and disease activity (p = 0.045) scores than those with less physical activity. CONCLUSION Physical activity in RA patients was significantly correlated with functional capacity and levels of fatigue. In order to reduce the proportion of patients with low physical activity, the possibilities for functional training should be expanded and the patients should be encouraged to undertake sporting activities.

Abstract
Abstract
Background
The importance of a sustainable health workforce is increasingly recognised. However, the specialised heath workforce remains marginal in health workforce planning, policy and research. This paper aims to improve the integration of small specialised professional groups in health workforce governance and to critically assess existing tools, using Germany and rheumatology physicians as a case study.
Methods
A qualitative explorative approach was applied, which draws on a scoping review of the literature, public statistics and expert information. The National Health Workforce Accounts (NHWA) and the WHO 'AAAQ' framework served as guidance to assess workforce development in rheumatology in Germany.

On average physician density is high in Germany, yet access to specialised care may be seriously delayed and services may not be accessible to all patients; e.g. currently only half of the patients with spondyloarthritis are treated by a rheumatologist which impacts quality of care. An estimated 850 to 1000 additional rheumatologists are needed to ensure early diagnoses and treatment and prevent long-term health damage. However, shortage will even reinforce in future: annual inflow of newly registered rheumatologists over recent years did not exceed 30 to 50 physicians and young rheumatologists more often prefer part-time work.
Conclusions
Specialised health professions with small numbers and long duration of training face specific challenges to create a sustainable workforce. This calls for (1) greater investment in education and training, (2) greater attention to qualitative indicators, such as assess and prevention measurements like early diagnosis, and (3) a dynamic health workforce approach to respond to both new technologies/ treatments and changing preferences of the health professionals, like part-time work.
Key messages
Integrating the specialised health workforce in health workforce governance is important to improve prevention, quality and access to care. NHWA may be aligned to qualitative indicators and prevention policies to respond more effectively to future population needs.

Abstract
A 64-year-old male patient developed over a period of 20 years a peripheral neuropathy symmetrically affecting the upper and lower limbs. The histological examination of a sural nerve biopsy revealed a severe axonal neuropathy. Despite extensive laboratory investigations including immunological and metabolic tests the origin could not be identified. Finally, a Schirmer test revealed xerophthalmia. A subsequent salivary gland biopsy from the lower lip revealed a grade III lymphocytic inflammation according to Chisholm and Mason and confirmed the diagnosis of Sjögren's syndrome.

Abstract
Background:Interstitial lung disease (ILD) represents a frequent extra-glandular manifestation of primary Sjögren’s Syndrome (pSS). Limited published data regarding phenotyping and treatment exists. Advances in managing specific ILD phenotypes have not been comprehensively explored in patients with coexisting pSS.Objectives:This retrospective study aimed to phenotype lung diseases occurring in a well-described pSS cohort and describe treatment course and outcomes.Methods:Between April 2018 and September 2019, all pSS patients attending our Outpatient clinic were screened for possible lung involvement. Clinical, laboratory and computer tomography (CT) findings were analysed. Patients were classified according to CT findings into 5 groups: usual interstitial pneumonia (UIP), non-specific interstitial pneumonia (NSIP), desquamative interstitial pneumonia (DIP), combined pulmonary fibrosis and emphysema (CPFE) and unspecific-ILD.Results:Lung involvement was confirmed in 24/240 patients (10%). Clinically manifest pSS occurred later in patients with ILD vs. non-ILD (53.2 [42.0-61.7]vs.62.3 [55.6-68.8] years; p=0.0016). The commonest phenotype was UIP n=10 (41%), followed by NSIP n=7 (29%), DIP n=2 (8%), CPFE n=2 (8%) and unspecific-ILD n=3 (13%). Forced vital capacity (FVC) and carbon monoxide diffusion capacity (DLCO) appeared lower in UIP and DIP, without reaching a significant difference. Treatment focused universally on intensified immunosuppression, with 12/24 patients (50%) receiving cyclophosphamide. No anti-fibrotic treatments were used. Follow-up was median 13.2 [7.9-72.3] months, during which 6/24 (25%) patients exhibited a further decline in FVC. No deaths occurred.Conclusion:Lung involvement in pSS is heterogeneous. Better phenotyping and tailored treatment may improve outcomes and requires further evaluation in larger prospective studies.Disclosure of Interests:None declared

Abstract
BACKGROUND B cells play a central role in IgE-mediated allergies. In damaged airway epithelium, they are exposed directly to aeroallergens. We aimed to assess whether direct exposure of B cells to pollen constituents affects allergic sensitization. METHODS B cells from murine splenocytes and from blood samples of healthy donors were incubated for 8 days under Th2-like conditions with aqueous ragweed pollen extracts (Amb-APE) or its constituents. Secreted total IgM, IgG, and IgE was quantified by ELISA. Additionally, birch, grass, or pine-pollen extracts were tested. The number of viable cells was evaluated by ATP measurements. B-cell proliferation was measured by CFSE staining. IgE class switch was analyzed by quantitation of class switch transcripts. In an OVA/Alum i.p.-sensitization mouse model, Amb-APE was intranasally instilled for 11 consecutive days. RESULTS Upon Th2 priming of murine B cells, ragweed pollen extract caused a dose-dependent increase in IgE production, while IgG and IgM were not affected. The low-molecular-weight fraction and phytoprostane E1 (PPE1) increased IgE production, while Amb a 1 did not. PPE1 enhanced IgE also in human memory B cells. Under Th1 conditions, Amb-APE did not influence immunoglobulin secretion. The IgE elevation was not ragweed specific. It correlated with proliferation of viable B cells, but not with IgE class switch. In vivo, Amb-APE increased total IgE and showed adjuvant activity in allergic airway inflammation. CONCLUSIONS Aqueous pollen extracts, the protein-free fraction of Amb-APE, and the pollen-contained substance PPE1 specifically enhance IgE production in Th2-primed B cells. Thus, pollen-derived nonallergenic substances might be responsible for B-cell-dependent aggravation of IgE-mediated allergies.

Abstract
BACKGROUND Ragweed (Ambrosia artemisiifolia) is a strong elicitor of allergic airway inflammation with worldwide increasing prevalence. Various components of ragweed pollen are thought to play a role in the development of allergic responses. The aim of this study was to identify critical factors for allergenicity of ragweed pollen in a physiological model of allergic airway inflammation. METHODS Aqueous ragweed pollen extract, the low molecular weight fraction or the major allergen Amb a 1 was instilled intranasally on 1-11 consecutive days, and allergic airway inflammation was evaluated by bronchoalveolar lavage, lung histology, serology, gene expression in lung tissue, and measurement of lung function. Pollen-derived adenosine was removed from the extract enzymatically to analyze its role in ragweed-induced allergy. Migration of human neutrophils and eosinophils toward supernatants of ragweed-stimulated bronchial epithelial cells was analyzed. RESULTS Instillation of ragweed pollen extract, but not of the major allergen or the low molecular weight fraction, induced specific IgG1 , pulmonary infiltration with inflammatory cells, a Th2-associated cytokine signature in pulmonary tissue, and impaired lung function. Adenosine aggravated ragweed-induced allergic lung inflammation. In vitro, human neutrophils and eosinophils migrated toward supernatants of bronchial epithelial cells stimulated with ragweed extract only if adenosine was present. CONCLUSIONS Pollen-derived adenosine is a critical factor in ragweed-pollen-induced allergic airway inflammation. Future studies aim at therapeutic strategies to control these allergen-independent pathways.

Abstract
INTRODUCTION Although cardiac complications have been reported in established spondyloarthritis (SpA), little is known about peripheral axial SpA in large vessel vasculitis (LVV). The aim of this study was to assess the prevalence of SpA in patients with newly diagnosed LVV. METHOD Retrospective single-centre analysis of all newly diagnosed LVV patients was performed between January 2011 and December 2012. Vasculitides were confirmed on thoracic magnetic resonance imaging (MRI) or 18-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT). Patients completed a standardized questionnaire incorporating the Berlin criteria to assess inflammatory back pain. Existing scans were reassessed for sacroiliitis and ferritin antibodies measured in all patients. RESULTS Fifteen patients exhibiting new LVV were identified. Diagnosis was confirmed using MRI in nine patients and FDG-PET/CT in six. Six patients (40%) fulfilled American College of Rheumatology (ACR) criteria for giant cell arteritis (GCA) and polymyalgia rheumatica (PMR), and nine PMR only. Four patients fulfilled the Berlin criteria for inflammatory back pain, with three demonstrating sacroiliitis on imaging. All remaining patients demonstrated no sacroiliitis. One further patient with LVV lacking features of inflammatory back pain had known psoriatic arthritis (PsA). Patients with coexisting SpA were younger (mean age 57 years vs. 66 years) and had higher C-reactive protein (CRP) levels (200 mg/L vs. 85 mg/L) at presentation. Four SpA patients and seven out of nine patients with isolated LVV had ferritin antibodies. CONCLUSIONS We have demonstrated a higher than anticipated prevalence of SpA in LVV, given the reported 0.5-1% prevalence in the general population. Coexisting SpA should be considered in LVV patients exhibiting inflammatory back pain despite steroid initiation. Ferritin antibodies demonstrated a similarly high prevalence in aortitis and SpA as reported previously in untreated GCA and PMR.

Abstract
Splenectomy has been used in patients with common variable immunodeficiency disorders (CVID), mainly in the context of refractory autoimmune cytopenia and suspected lymphoma, but there are understandable concerns about the potential of compounding an existing immunodeficiency. With increasing use of rituximab as an alternative treatment for refractory autoimmune cytopenia, the role of splenectomy in CVID needs to be re-examined. This retrospective study provides the largest cohesive data set to date describing the outcome of splenectomy in 45 CVID patients in the past 40 years. Splenectomy proved to be an effective long-term treatment in 75% of CVID patients with autoimmune cytopenia, even in some cases when rituximab had failed. Splenectomy does not worsen mortality in CVID and adequate immunoglobulin replacement therapy appears to play a protective role in overwhelming post-splenectomy infections. Future trials comparing the effectiveness and safety of rituximab and splenectomy are needed to provide clearer guidance on the second-line management of autoimmune cytopenia in CVID.

Abstract
AIMS/HYPOTHESIS Sphingolipid synthesis is typically initiated by the conjugation of L-serine and palmitoyl-CoA, a reaction catalysed by serine palmitoyltransferase (SPT). SPT can also metabolise other acyl-CoAs (C(12) to C(18)) and other amino acids such as L-alanine and glycine, giving rise to a spectrum of atypical sphingolipids. Here, we aimed to identify changes in plasma levels of these atypical sphingolipids to explore their potential as biomarkers in the metabolic syndrome and diabetes. METHODS We compared the plasma profiles of ten sphingoid bases in healthy individuals with those of patients with the metabolic syndrome but not diabetes, and diabetic patients (n = 25 per group). The results were verified in a streptozotocin (STZ) rat model. Univariate and multivariate statistical analyses were used. RESULTS Deoxysphingolipids (dSLs) were significantly elevated (p = 5 × 10⁻⁶) in patients with the metabolic syndrome (0.11 ± 0.04 μmol/l) compared with controls (0.06 ± 0.02 μmol/l) but did not differ between the metabolic syndrome and diabetes groups. Levels of C(16)-sphingosine-based sphingolipids were significantly lowered in diabetic patients but not in patients with the metabolic syndrome but without diabetes (p = 0.008). Significantly elevated dSL levels were also found in the plasma and liver of STZ rats. A principal component analysis revealed a similar or even closer association of dSLs with diabetes and the metabolic syndrome in comparison with the established biomarkers. CONCLUSIONS/INTERPRETATION We showed that dSLs are significantly elevated in patients with type 2 diabetes mellitus and non-diabetic metabolic syndrome compared with healthy controls. They may, therefore, be useful novel biomarkers to improve risk prediction and therapy monitoring in these patients.

Abstract
Forests in Europe face significant changes in climate, which in interaction with air quality changes, may significantly affect forest productivity, stand composition and carbon sequestration in both vegetation and soils. Identified knowledge gaps and research needs include: (i) interaction between changes in air quality (trace gas concentrations), climate and other site factors on forest ecosystem response, (ii) significance of biotic processes in system response, (iii) tools for mechanistic and diagnostic understanding and upscaling, and (iv) the need for unifying modelling and empirical research for synthesis. This position paper highlights the above focuses, including the global dimension of air pollution as part of climate change and the need for knowledge transfer to enable reliable risk assessment. A new type of research site in forest ecosystems ("supersites") will be conducive to addressing these gaps by enabling integration of experimentation and modelling within the soil-plant-atmosphere interface, as well as further model development.

Abstract
This study aims to assess whether or not incomplete filling of primary lithium heparin tubes may influence the activity of creatine kinase (CK), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyltransferase (GGT). Blood was drawn from 20 healthy volunteer using an identical sequence of tubes. First, a 6 mL, 13 x 100 mm 14 unit/mL lithium heparin Vacuette was filled and discharged. Then, three identical lithium heparin Vacuette tubes were filled, one to the nominal volume (i.e., full-draw tube), another with half of the nominal volume (half-draw tube) and the last with one-third of the nominal volume (low-draw tube). The plasma was separated and tested for CK (non-activated by N-acetylcysteine), AST and ALT on a Beckman Coulter Unicel DxC 800. Tests for CK were performed with a different reagent on a Beckman Coulter AU5800 (activated by N-acetylcysteine). Although the concentrations of ASL and ALT measured on the Unicel DxC and that of CK measured on the AU5800 did not change significantly across the different specimens, those of CK and GGT measured on the Unicel DxC 800 were significantly increased in the half-draw and low-draw tubes. The percentage bias of CK on the Unicel DxC 800 (using Bland Altman plots) was 3.3% and 7.9% for the half-draw and low-draw tubes, respectively, whereas that of GGT was 10.3% and 16.6% for the half-draw and low-draw tubes, respectively. These results suggest that short-draw lithium heparin tubes might be unsuitable for testing GGT and CK using specific combinations of reagents and instrumentation.

Abstract
BACKGROUND Tamoxifen (TX) represents the prototype selective oestrogen receptor modulator. In addition to its use in breast cancer, TX possesses immunomodulatory functions and displays beneficial effects in models of systemic lupus erythematosus. We hypothesized that TX might inhibit type I allergic reactions, which are also characterized by deviations in humoral immunity. OBJECTIVE To evaluate the effects of TX on the allergic immune response in appropriate mouse models. METHODS Balb/c mice were sensitized with ovalbumin (OVA)-alum by the intraperitoneal route, and humoral parameters, T cell cytokine patterns and OVA-induced ear swelling responses were determined in a preventive (start of TX treatment before sensitization) and a therapeutic setting (start after sensitization), respectively. In addition, the impact of TX on clinical signs, epidermal thickness and leucocyte infiltration of the skin was investigated in a model of allergen-induced dermatitis. RESULTS Preventive TX treatment interfered with all aspects of the allergic immune response, leading to a reduction of allergen-specific Ig levels (IgE, IgG1 and IgG2a), a skewing effect in the T cell compartment with the inhibition of IL-4 and an abrogation of ear swelling responses. Interestingly, a therapeutic TX administration was also effective in reducing Ig levels and ear swelling responses. The vigorous systemic effects were additionally mirrored by local changes in allergen-dependent dermatitis with reduced clinical symptoms, diminished epidermal thickness and decreased CD4+ and CD8+ cell infiltrates. CONCLUSION TX inhibits allergic responses when given preventively and also therapeutically, and improves allergen-induced dermatitis. Because of its effectiveness, TX could bear significant therapeutic potential for the treatment of allergies.

Abstract
Upcoming decades will experience increasing atmospheric CO2 and likely enhanced O3 exposure which represents a risk for the carbon sink strength of forests, so that the need for cause-effect related O3 risk assessment increases. Although assessment will gain in reliability on an O3 uptake basis, risk is co-determined by the effective dose, i.e. the plant's sensitivity per O3 uptake. Recent progress in research on the molecular and metabolic control of the effective O3 dose is reported along with advances in empirically assessing O3 uptake at the whole-tree and stand level. Knowledge on both O3 uptake and effective dose (measures of stress avoidance and tolerance, respectively) needs to be understood mechanistically and linked as a pre-requisite before practical use of process-based O3 risk assessment can be implemented. To this end, perspectives are derived for validating and promoting new O3 flux-based modelling tools.

Abstract
Ozone and light effects on endophytic colonization by Apiognomonia errabunda of adult beech trees (Fagus sylvatica) and their putative mediation by internal defence compounds were studied at the Kranzberg Forest free-air ozone fumigation site. A. errabunda colonization was quantified by "real-time PCR" (QPCR). A. errabunda-specific primers allowed detection without interference by DNA from European beech and several species of common genera of plant pathogenic fungi, such as Mycosphaerella, Alternaria, Botrytis, and Fusarium. Colonization levels of sun and shade leaves of European beech trees exposed either to ambient or twice ambient ozone regimes were determined. Colonization was significantly higher in shade compared to sun leaves. Ozone exhibited a marginally inhibitory effect on fungal colonization only in young leaves in 2002. The hot and dry summer of 2003 reduced fungal colonization dramatically, being more pronounced than ozone treatment or sun exposure. Levels of soluble and cell wall-bound phenolic compounds were approximately twice as high in sun than in shade leaves. Acylated flavonol 3- O-glycosides with putatively high UV-B shielding effect were very low in shade canopy leaves. Ozone had only a minor influence on secondary metabolites in sun leaves. It slightly increased kaempferol 3- O-glucoside levels exclusively in shade leaves. The frequently prominent hydroxycinnamic acid derivative, chlorogenic acid, was tested for its growth inhibiting activity against Apiognomonia and showed an IC50 of approximately 8 mM. Appearance of Apiognomonia-related necroses strongly correlated with the occurrence of the stress metabolite, 3,3',4,4'-tetramethoxybiphenyl. Infection success of Apiognomonia was highly dependent on light exposure, presumably affected by the endogenous levels of constitutive phenolic compounds. Ozone exerted only minor modulating effects, whereas climatic factors, such as pronounced heat periods and drought, were dramatically overriding.

Abstract
Suppression subtractive hybridization (SSH) was performed to isolate cDNAs representing genes that are differentially expressed in leaves of Fagus sylvatica upon ozone exposure. 1248 expressed sequence tags (ESTs) were obtained from 2 subtractive libraries containing early and late ozone-responsive genes. Sequences of 1139 clones (91 %) matched the EBI/NCBI database entries. For 578 clones, no putative function could be assigned. Most abundant transcripts were O-methyltransferases, representing 7 % of all sequenced clones. ESTs were organized into 12 functional categories according to the MIPS database. Among them, 12 % (early)/15 % (late) were associated with disease and defence, 19/11 % with cell structure, 4/10 % with signal transduction, and 9/6 % with transcription. The expression pattern of selected ESTs (ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit [rbcS], WRKY-type transcription factor, ultraviolet-B-repressible protein, aquaporine, glutathione S-transferase, catalase, caffeic acid O-methyltransferase, and pathogenesis-related protein 1 [PR1]) was analysed by quantitative real-time RT-PCR (qRT-PCR) which confirmed changed transcript levels upon ozone treatment of European beech saplings. The ESTs characterized will contribute to a better understanding of forest tree genomics and also to a comparison of ozone-responsive genes in woody and herbaceous plants.
