Infektiologische Versorgung minderjähriger Flüchtlinge am Beispiel der Ukraine

Hintergrund

Bis Anfang Juni 2022 sind ca. 300.000 Kinder und Jugendliche aus der Ukraine im deutschen Ausländerzentralregister registriert worden.

Die vorliegenden Handlungsempfehlungen sollen die Grundlage für eine evidenzbasierte und zielgerichtete infektiologische Versorgung minderjähriger Flüchtlinge am Beispiel der Ukraine schaffen.

Ziele

Die Handlungsempfehlungen sollen medizinisches Personal in der Versorgung minderjähriger Flüchtlinge aus der Ukraine unterstützen, um

1. einen unvollständigen Impfschutz frühzeitig zu erkennen und zu vervollständigen;

2. übliche Infektionskrankheiten zu diagnostizieren und zu behandeln;

3. in Deutschland seltene Infektionskrankheiten frühzeitig zu erkennen und zu therapieren.

Material und Methoden

Die Handlungsempfehlungen wurden als durch die Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF) koordinierte Leitlinie der Stufe 1 verfasst und an die Situation Flucht aus der Ukraine angepasst.

Die Empfehlungen wurden durch eine repräsentativ zusammengesetzte Expertengruppe der beteiligten Fachgesellschaften im informellen Konsens erarbeitet und final von den Vorständen der Fachgesellschaften offiziell verabschiedet.

Ergebnisse

Es werden Empfehlungen für den Umfang der Anamnese und der körperlichen Untersuchung minderjähriger Flüchtlinge, angepasst an die Situation Flucht aus der Ukraine, ausgesprochen. Für alle minderjährigen Flüchtlinge werden die Bestimmung eines Differenzialblutbilds sowie Untersuchungen auf Tuberkulose, Hepatitis B und C sowie eine Human-Immunodeficiency-Virus(HIV)-Infektion empfohlen.

Zur raschen Vervollständigung des Impfstatus wird eine alters- und Indikationsbezogene Priorisierung einzelner Impfungen vorgenommen.

Diskussion

Angesichts anhaltend hoher Flüchtlingszahlen nicht nur aus der Ukraine ist eine weitere Professionalisierung der medizinischen Versorgung minderjähriger Flüchtlinge notwendig. Hierzu sollten die notwendigen strukturellen und personellen Rahmenbedingungen geschaffen werden.

Axillary Staging after Neoadjuvant Chemotherapy for Initially Node-Positive Breast Carcinoma in Germany: Initial Data from the AXSANA study

Introduction To date, the optimal axillary staging procedure for initially node-positive breast carcinoma patients after neoadjuvant chemotherapy (NACT) has been unclear. The aim of the AXSANA study is to prospectively compare different surgical staging techniques with respect to the oncological outcome and quality of life for the patients. Little is known about current clinical practice in Germany. Material and Methods In this paper we analyzed data from patients enrolled in the AXSANA study at German study sites from June 2020 to March 2022. Results During the period under investigation, 1135 patients were recruited at 143 study sites. More than three suspicious lymph nodes were initially found in 22% of patients. The target lymph node (TLN) was marked in 64% of cases. This was done with clips/coils in 83% of patients, with magnetic seeds or carbon suspension in 8% each, and with a radar marker in 1% of patients. After NACT, targeted axillary dissection (TAD) or axillary lymphadenectomy (ALND) were each planned in 48% of patients, and sentinel lymph node biopsy alone (SLNB) in 2%. Clinically, the nodal status after NACT was found to be unremarkable in 65% of cases. Histological lymph node status was correctly assessed by palpation in 65% of patients and by sonography in 69% of patients. Conclusion At the German AXSANA study sites, TAD and ALND are currently used as the most common surgical staging procedures after NACT in initially node-positive breast cancer patients. The TLN is marked with various markers prior to NACT. Given the inadequate accuracy of clinical assessment of axillary lymph node status after NACT, it should be questioned whether axillary dissection after NACT should be performed based on clinical assessment of nodal status alone.

POS0170 EXPERIENCES WITH COVID-19 INFECTIONS IN GERMAN PEDIATRIC RHEUMATOLOGY CENTERS

Background

Although the risk for severe COVID-19 progression in children is low, this may be aggravated by the underlying disease and/or immunosuppressive drugs.

Objectives

We analyzed clinical data of COVID-19 cases among paediatric patients with rheumatic diseases reported to the BIKER registry.

Methods

The main task of the German BIKER (Biologics in Pediatric Rheumatology) registry is to monitor the safety of biologics therapies in JIA. After the onset of the COVID-19 pandemic, the survey was expanded with a standardized form to proactively interview all participating centers about the occurrence, presentation, and outcome of SARS-CoV-2- infections in children with rheumatic diseases. Interviews were conducted with 68 centers initially weekly and later biweekly.

Results

A total of 68 centres participated in the survey. Clinical data from 194 COVID-19 cases reported to the BIKER registry from 41 German and 1 Austrian pediatric rheumatology institutions between February 2020 and December 2021 were analyzed. Juvenile idiopathic arthritis (JIA, n=144) was the most common diagnosis followed by genetic autoinflammation (n=18; i.e. FMF, TRAPS, CAPS, HIDS, DADA2), systemic autoimmune diseases (n=11; i.e. SLE, dermatomyositis, vasculitis) and 16 with other rheumatic diseases (i.e. CRMO, Uveitis). 5 patients with no rheumatic disease were excluded. 104 (54%) patients were receiving conventional DMARDs, 81 (43%) received biologics, mainly TNF inhibitors (n=66 (35%)).

Of the 189 rheumatic patients with SARS-CoV2 infection, 123 (63%) were female. The mean age was 12.4+/-4.4 years in females and 13.2+/-4.1 in males. The duration of SARS-Co2 infection associated symptoms was 13.8+/-15.3 days (max. 113 days), in 35 (43%) patients they lasted for > 12 days. 46 (24%) were asymptomatic. Patients with autoinflammation and systemic autoimmunopathies reported more symptoms such as fever, head and throat ache. 4 patients only complained about dyspnea.

Only 3 patients were hospitalized and received Oxygen-supplementation. The only patients admitted to ICU, received ventilation but succumbed. This 3½-year-old patient, initially diagnosed with systemic JIA, developed fatal disease with intracranial edema and respiratory failure, as well as typical pulmonary texture changes. Prior to her SARS-CoV-2 infection, the patient was treated with MTX and low-dose steroids. Genetic testing revealed a so far unrecognized congenital immunodeficiency.

In the total JIA cohort, treatment with corticosteroids, conventional DMARDs, biologics or combinations did not influence the number of reported symptoms or the favorable outcome of the cohort. However, the duration of symptoms was lower in the TNF-treated cohort (10.4+/-6.4 days vs. 15.7 +/- 19.7 days). In the cohort with autoinflammation, fever was observed in 11 (61%). Those 6 who received IL-1-inhibitors did not show a different outcome than those 12 who did not. No case of PIMS/MISC in children with rheumatic diseases was reported.

Conclusion

Except for one patient with congenital immunodeficiency who died from her COVID-19 infection, no case of severe COVID-19 was reported in our cohort. At the time of infection, over 80% of patients in our cohort had been treated with conventional DMARDs and/or biologics. This did not appear to have a negative impact on the severity or outcome of SARS-CoV2 infection. Interestingly, no case of PIMS/MISC was observed.

POS1374 LONG-TERM SAFETY OF CANAKINUMAB IN PATIENTS WITH AUTOINFLAMMATORY DISEASES - INTERIM ANALYSIS OF THE RELIANCE REGISTRY

Background

Autoinflammatory diseases (AID) are characterized by severe systemic and organ inflammation as well as high burden of disease for patients and their families. Treatment with the monoclonal antibody canakinumab (CAN), an interleukin-1β inhibitor, has been proven to be safe and effective in clinical trials and real-life.

Objectives

The present study explores the long-term efficacy and safety of CAN in routine clinical practice conditions in pediatric (age ≥2 years) and adult patients with CAPS (cryopyrin-associated periodic syndromes), FMF (familial Mediterranean fever), TRAPS (tumor necrosis factor receptor-associated periodic syndrome) and HIDS/MKD (hyperimmunoglobulinemia D syndrome/mevalonate kinase deficiency).

Methods

RELIANCE is a prospective, non-interventional, observational study based in Germany. Patients with clinically confirmed diagnoses of AID routinely receiving CAN are enrolled. Besides efficacy parameters regarding disease activity and remission, safety parameters were recorded at baseline and assessed at 6-monthly intervals.

Results

Here, we present the interim analysis of patients with AID (N=199) enrolled in the RELIANCE Registry between October 2017 and December 2021. Mean age in this cohort was 24.4 years (2–79 years) and the proportion of female patients was 53% (N=104). At baseline, median duration of prior CAN treatment was 2 years (0–12 years).

A total of 123 patients (62%) experienced any AE (N=653) among which nasopharyngitis, increase of inflammatory markers and pyrexia were the most frequent AE with incidence rates per 100 patient years (IR) of 8.3, 6.2, and 6.2, respectively.

29 patients (15%) were affected by severe AE (SAE, total number N=90) including 11 patients (6%) with SAE suspected to be drug-related (SADR; total number N=30) with IR from 0.2 to 0.7 (Table 1). Overall, 16 AE comprised upper respiratory tract infections (URI). One death (COVID-19, not related) and one malignancy (skin papilloma, not related) were reported. No vertigo and no hypersensitivity reactions were observed. N=10 (IR 2.36) vaccination reactions were reported (no SAE).

Conclusion

The interim data from the RELIANCE study, the longest running real-life canakinumab registry, confirm safety of long-term canakinumab treatment across the entire study population. A trend for dose-related increase of SAE/SADR requires continuous close monitoring and awareness in patient groups (children, severe phenotypes, certain genotypes) requiring greater than standard dose treatment regimens.

OP0217 EFFECTIVENESS AND SAFETY OF IL-6 INHIBITION (TOCILIZUMAB) VERSUS TUMOUR NECROSIS FACTOR INHIBITION IN POLYARTICULAR JUVENILE IDIOPATHIC ARTHRITIS: RESULTS FROM THE OBSERVATIONAL BIKER STUDY

Background

Tocilizumab (TCZ) has been approved for treatment of juvenile idiopathic arthritis (JIA) for 10 years.

Objectives

Evaluation of 12-month efficacy and safety of TCZ compared to TNF inhibitors (TNFi).

Methods

BIKER WA 29358 is a 5-year multi-centre prospective, observational cohort study including polyarticular JIA patients in Germany starting treatment between 2015 and 2020 with TCZ and matched 1:1 by date of treatment start and region to patients starting an approved TNFi. Clinical disease activity (JADAS10), JADAS MDA (≦3.8)/remission (≦1.0), safety and drug adherence at 12 months were assessed and compared between cohorts.

Results

The analysis included 342 participants with 12-month treatment data (TCZ n=171; TNFi n=171). TCZ was used as 2nd line biologic in the majority of patients (84%) while TNFi were mostly 1st line biologics (86%). Patients starting TCZ had a longer disease duration. Efficacy was demonstrated by a marked decrease in JADAS10 in both cohorts (TCZ vs. TNFi at baseline: 15.0+/-6.7 vs. 14.6+/-6.3; at month 12: 3.8+/-5.1 vs. 3.4+/-4.5). Proportions of patients in TCZ/TNFi cohorts achieving JADAS remission at 12 months were 48%/41% in 1st line biologic users and 32%/33% in 2nd line biologic users. JADAS MDA was achieved in 64%/69% in 1st line and 52%/58% in 2nd line users of TCZ/TNFi.

After 12 months of treatment JADAS10 (mean +/SD) was higher in the 2nd line TNFi cohort compared to the 1st line (4.5+/-5.6 vs. 3.2+/-4.3), similar to patients receiving 2nd or 1st line TCZ (4.0+/-5.2 vs. 2.9+/-4.4). Patients receiving TCZ or TNFi as first biologic reached JADAS10 remission and MDA numerically more frequently but not statistically significant compared to 2nd line users.

Safety was assessed based on adverse event (AE) reporting. 57 (33%) patients in the TCZ cohort and 43 (25%) patients in the TNFi cohort reported AE. The AE rate was significantly higher in the TCZ cohort (69 vs. 44.8/100 patient years, RR 1.5 [95%CI 1.1-2.0], p=0.006, Wald-test). There were 6 serious AE in the TCZ and 3 in the TNFi cohort. Injection site reactions were more common in the TNFi cohort (9 vs. 1, p=0.043). No further differences were identified to date. There was no death and no opportunistic infection.

In the TCZ cohort, 32 patients discontinued treatment, 27 due to lack of efficacy, while in the TNFi cohort only 6 patients discontinued treatment. Treatment discontinuation was more frequent among the 2nd biologic users (n=29; 17.4%) than in first line users (n= 9; 5.1%).

Conclusion

In this first interim analysis, treatment targets were reached with similar frequency after 12 months of treatment with TCZ or TNFi. TCZ was used predominantly as 2nd line biologic. Higher rates of remission /MDA were observed in 1st line compared to 2nd line biologic users. Although more AE were reported in the TCZ cohort, the occurrence of serious AE and infections was comparable in both cohorts. No new safety signals were identified. Observation is ongoing.

POS0221 LONG-TERM EFFICACY AND SAFETY OF CANAKINUMAB IN PATIENTS WITH TRAPS (TUMOR NECROSIS FACTOR RECEPTOR-ASSOCIATED PERIODIC SYNDROME) – INTERIM ANALYSIS OF THE RELIANCE REGISTRY

Background

Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is a rare hereditary autoinflammatory disease characterized by periodic fever as well as severe systemic and organ inflammation. Successful treatment was achieved with the interleukin-1β inhibitor canakinumab (CAN) in a pivotal phase 3 study, in which 45% of patients reached clinical remission after 16 weeks (primary endpoint)1. CAN has been approved and applied for the treatment of TRAPS patients since 20172.

Objectives

The present study explores the long-term efficacy and safety of CAN under routine clinical practice conditions in pediatric (age ≥2 years) and adult TRAPS patients.

Methods

RELIANCE is a prospective, non-interventional, multi-center, observational study based in Germany. Patients with clinically confirmed diagnosis of TRAPS who routinely receive CAN are enrolled in order to evaluate efficacy and safety of CAN under standard clinical practice conditions at baseline and at 6-monthly intervals.

Results

The interim analysis of TRAPS patients enrolled by December 2021 includes baseline (N=19, 1 patient with atypical TRAPS) and preliminary 24-month data. Of these patients, N=12 (63%) were females and median age at baseline was 16 years (3–43 years).

Preliminary results indicate stable remission by physicians´ assessment and laboratory parameters. Disease control by patients´ assessment showed no major changes over time (Table 1). In total, N=7 adverse drug reactions where observed, of which none was classified as severe.

POS0171 A STANDARDIZED ASSESSMENT OF TREATMENT AND OUTCOME OF NEWLY DIAGNOSED PATIENTS WITH JIA WITHIN THE PROKIND PROJECT – PATHWAYS FOR POLYARTICULAR JIA

Background

The ProKind Commission of the Society for Paediatric and Adolescent Rheumatology (GKJR) has developed evidence- and consensus-based protocols for the diagnosis and therapy of children and adolescents with defined rheumatic diseases (e.g., [1]). In the ProKind-Rheuma project, it is now investigated whether the protocols are followed in everyday clinical practice and what the treatment-associated outcomes are.

Objectives

To investigate the mode of treatment and treatment response in patients with polyarticular juvenile idiopathic arthritis (pJIA).

Methods

ProKind-Rheuma is a multicenter prospective non-interventional observational study. Patients with pJIA enrolled until 17/1/2022 were included into this analysis. Treatments and outcomes up to the 3-month follow-up visit (3FU) were analyzed. Disease states were categorized based on the 2021 cJADAS10 cutoffs [2].

Results

To date, 18 pediatric rheumatology facilities have participated in ProKind-Rheuma. Data from 203 patients with JIA are available. Of those, 44% have oligoarthritis, 36% polyarthritis, 9% systemic JIA, 6% enthesitis-related arthritis and 3% psoriatic arthritis.

In total, 76 patients were diagnosed with pJIA, 38 with already completed 3FU:

For 23 patients with pJIA and completed 3FU, we were able to analyze the protocol-defined [1] treatment goal of at least “minimal improvement”. In total, 18 (78%) achieved minimal improvement, 5 (22%) missed it. For 4 of those 5 patients, the underlying MTX therapy was escalated to a bDMARD (3 changed to MTX+bDMARD-combi, 1 to bDMARD-mono). In 3 other patients, therapy was also escalated to an MTX+bDMARD-combi.

Between baseline and 3FU, 72% achieved cJADAS10-disease state improvement (Table 1) by at least one category (range 1 - 2), 0% decreased.

Within the first 3 months after diagnosis, the treatment pathways proposed by the ProKind Commission [1] were followed in about three-quarters of patients: i) 5 (13%) received MTX and intra-articular glucocorticoid injections in more than 4 joints (IAGC), but no high-dose intravenous glucocorticoid pulse (HDGC) or bDMARD; ii) 8 (21%) received MTX and HDGC (no bDMARD, no IAGC); iii) 16 (42%) patients received MTX, of whom 4 received a bDMARD up to or at the 3FU (no HDGC, no IAGC). Nine (24%) patients were not treated with MTX or did not fit any of these categories, mostly due to starting bDMARD therapy in conjunction with HDGC or IAGC.

Conclusion

In the routine care of JIA patients with polyarthritis, the proposed treatment protocol and treat-to-target strategy are followed in most patients. At 3FU, improvements of JADAS10 and other outcomes were evident, with 41% having achieved inactive or minimal active disease.

POS0338 TRANSITION COMPETENCE IN YOUNG PEOPLE WITH JUVENILE IDIOPATHIC ARTHRITIS HAS IMPROVED OVER TIME

Background

In recent years, transition clinics have been set up at an increasing number of paediatric rheumatology sites in Germany to reduce identified deficits in the care of young people with rheumatic diseases1. In addition, the German Rheumatic Diseases League (Deutsche Rheuma-Liga, DRL), the largest self-help organisation in Germany, has been offering support services for young people in transition since 2016, including the interactive website www.mein-rheuma-wird-erwachsen.de.

Objectives

To assess the transition competence of young people with juvenile idiopathic arthritis (JIA) and their knowledge of self-help services.

Methods

Cross-sectional data of the National Paediatric Rheumatology Database (NPRD) from 2016 to 2020 were used to evaluate the health-related transition competence of young people with JIA aged ≥16 years. Health-related knowledge and health-care competence were assessed using a modified self-report instrument2 on a 4-point Likert scale as part of routine documentation in the NPRD. Young people were also asked about their information behaviour and knowledge of new support services. Linear mixed models were used to determine whether health-related transition competence changed between 2016 and 2020, adjusted for disease duration.

Results

During the years 2016 to 2020, between 1.908 to 2.536 patients with JIA aged ≥16 years were annually recorded in the NPRD from 56 to 61 paediatric rheumatology sites. The annual patient collectives comprised 34-39% oligoarthritis, 23-26% RF-negative or RF-positive polyarthritis and 22-27% enthesitis-related arthritis cases. In the years from 2016 to 2020, about one-third of patients had inactive disease (cJADAS-10≤1) and about 60% had no functional limitations (CHAQ=0).

Over the years, the proportions of patients who rated their disease knowledge and health care competence as “very well” increased significantly in most areas. Although over time, no increase in numbers of patients seeking information about their disease outside of rheumatology consultations were recorded (2016: 22.8%; 2020: 20.9%), awareness of the DRL’s new website for young people with rheumatic diseases increased from 7.7% in 2016 to 26.9% in 2020. Compared to those who were unaware of the new website, those who knew about the website were more likely to have received care in rheumatology settings that offer transition clinics and were more likely to be girls (75% vs 65%), to attend high school (51% vs 46%) and to be slightly older (17.6 vs 17.1 years).

Conclusion

The transition competence of young people with JIA seems to have improved over the last five years. During this time, more transition services were made available for young people with rheumatic diseases. However, most young people are not yet aware of these services. Moreover, the effectiveness of the different measures/interventions has yet to be evaluated.

OP0042 LONG-TERM EFFICACY AND SAFETY OF CANAKINUMAB IN PATIENTS WITH FAMILIAL MEDITERRANEAN FEVER (FMF) - INTERIM ANALYSIS OF THE RELIANCE REGISTRY

Background

Familial Mediterranean Fever (FMF) is a chronic disease characterized by recurrent attacks of fever as well as serositis and bears the risk of serious complications (e. g. amyloidosis). Treatment of FMF according to EULAR aims to control acute attacks and subclinical inflammation as well as to improve patient´s quality of life1. Clinical data indicate that the inhibition of interleukin-1β with canakinumab (CAN) is effective in controlling and preventing flares in FMF patients2.

Objectives

The present study explores the long-term efficacy and safety of canakinumab in routine clinical practice conditions in pediatric (age ≥2 years) and adult FMF patients.

Methods

RELIANCE is a prospective, non-interventional, multi-center, observational study based in Germany with a 3-year follow-up period. Patients with clinically confirmed FMF diagnosis who routinely receive canakinumab are enrolled in order to evaluate effectiveness and safety of canakinumab. Disease activity and remission by physicians´ assessment, disease activity, fatigue and impact on social life by patients’ assessment, inflammatory markers and AIDAI (Auto-Inflammatory Diseases Activity Index) score were recorded at baseline and assessed at 6-monthly intervals within the 3-year observation period of the study.

Results

This interim analysis of FMF patients (N=74) enrolled by December 2021 includes baseline as well as 6- to 24-month data. Mean age in this cohort was 25 years (2−61 years) and the proportion of female patients was 51 % (N=38). At baseline, median duration of prior CAN treatment was 1.0 years (0−6 years).

At month 24, physician ratings report around 63% of patients in disease remission and patient-reported disease activity (mean PPA) decreased from moderate (3.0) to low (2.6) during the observation period. Other disease activity parameters also decreased (Table 1). A total of 18 serious adverse events were reported, of which 2 (1 case of tonsillectomy and 1 case of tachycardia) were classified as drug - related.

POS1202 EXPERIENCE WITH COVID-19 IN GERMAN PAEDIATRIC RHEUMATOLOGY CENTRES

Background:

COVID-19 is a major challenge worldwide. Although the risk for a severe disease course is low among children with COVID-19, symptoms may be exacerbated by underlying disease and/or immunosuppressive medication. We analysed clinical data from COVID-19 cases in among pediatric patients with juvenile idiopathic arthritis (JIA) in Germany reported to the BIKER registry.

Objectives:

This is an analysis of clinical data for 56 COVID-19 cases reported to the German BIKER registry from 29 German pediatric rheumatology centers and clinics from February 2020 to January 2021.

Methods:

The major task of the German BIKER (Biologics in Paediatric Rheumatology) Registry is surveillance of biologics used in pediatric rheumatology patients. Following the start of the COVID-19 pandemic in Germany, a survey was established to proactively interview all participating centers regarding the occurrence, presentation and outcome of SARS-CoV-2-infected children with rheumatic diseases. Initially, the interviews were conducted in weekly intervals, later bi-weekly.

A standardized Adverse Event of Special Interest form was developed requesting biographic data, pre-treatment, current medication, data on clinical presentation, course, treatment and outcome of COVID-19 pediatric rheumatology patients.

Results:

In all, 56 patients with JIA and SARS-CoV-2 infection were reported (Table 1). Of these patients, 71% were 12 or more years old.

Table 1.

At the time of infection, 41% of the patients received conventional DMARDs and 52% received biologics (Table 1). Forty-four patients (79%) received either a conventional DMARD or a biologic. Most patients had a polyarticular course of their JIA (57%).

In 49 of the 56 cases (88%) COVID-19 was detected directly by PCR (n=46), by antigen test only (n=1) or an undisclosed method (n= 2). Six patients had detectable SARS-CoV2 antibodies and reported to have had typical symptoms. One patient tested negative but developed typical symptoms at approximately the same time a positive SARS-CoV-2 test was returned for a family member.

Symptoms were reported in 43 of the 56 patients (77%): fever n=15, rhinitis n=14, cough n=12, headache n=10, loss of sense of taste and/or smell n=9, pharyngitis n=8, fatigue n=5, musculoskeletal pain n=5, GI symptoms n=2 (abdominal pain n=1, diarrhoea n=1), dizziness n=3, encephalitis/seizure/respiratory failure/death n=1. Thirteen patients (23%) were asymptomatic.

A 3½ -year-old female patient initially diagnosed with systemic JIA developed intracranial oedema and respiratory failure. Her SARS-CoV2 PCR test was positive and pulmonary imaging displayed typical changes in lung texture. Before her SARS-CoV-2 infection, the patient was treated with methotrexate and low-dose steroids. Unfortunately, she died three days following hospital admission. Genetic testing revealed an inborn immunodeficiency. Except for this one patient, all other cases were treated as outpatients and no deaths were reported.

Conclusion:

Apart from one patient with an inborn immunodeficiency who died from her COVID-19 infection, no case of hospitalization or severe COVID-19 was reported in our cohort of JIA patients. At the time of COVID-19 diagnosis, nearly 80% of patients in our cohort had been treated with conventional DMARD and/or biologics. This seemed not to have a negative effect on severity or outcome of SARS-CoV2 infection.

LB0004 EFFICACY AND SAFETY OF SECUKINUMAB IN ENTHESITIS-RELATED ARTHRITIS AND JUVENILE PSORIATIC ARTHRITIS: PRIMARY RESULTS FROM A RANDOMISED, DOUBLE-BLIND, PLACEBO-CONTROLLED, TREATMENT WITHDRAWAL, PHASE 3 STUDY (JUNIPERA)

Background:

Enthesitis-related arthritis (ERA) and juvenile psoriatic arthritis (JPsA) are two ILAR categories of juvenile idiopathic arthritis (JIA) and represent paediatric correlates of axial spondyloarthritis (axSpA) and adult psoriatic arthritis (PsA), respectively.1,2 Secukinumab (SEC) has demonstrated efficacy and safety in adult patients (pts) with PsA, ankylosing spondylitis and non-radiographic axSpA.3-5

Objectives:

Evaluate efficacy and safety of SEC using a flare prevention design in pts with active ERA and JPsA.

Methods:

This 2-yr study consisted of an open-label (OL) s.c. SEC (75/150 mg in pts <50/ ≥50 kg) at baseline (BL), and at Weeks (Wk) 1, 2, 3, 4, 8 and 12 in treatment-period (TP) 1. Responder pts who achieved at least JIA ACR 30 response at Wk 12 were randomised into the double-blinded TP2 to continue SEC or placebo (PBO) q4w until a disease flare, or up to Wk 100. Pts (aged 2 to <18 yrs) classified as ERA or JPsA according to ILAR criteria of ≥6 months duration with active disease were included. Primary endpoint was time to flare in TP2 and key secondary endpoints were JIA ACR 30/50/70/90/100, inactive disease, JADAS, enthesitis count and safety. Analysis of time to flare in TP2 included proportion of disease flare, Kaplan-Meier (KM) estimate of median time to flare in days, hazard ratio (95% CI) from Cox model, and P-value for the Stratified log-rank test. KM estimates of the probability to disease flare by treatment groups in TP2 were plotted against days. Observed data were used in all analyses. Post-hoc analyses using non-responder imputation (NRI) were performed for JIA ACR 30/50/70/90/100 responses.

Results:

86/97 (89%) pts were enrolled in the OL period TP1 (mean age, 13.1 yrs; female, 33.7%; ERA, n=52; JPsA, n=34). At BL, mean JADAS-27 score was 15.1 and enthesitis count was 2.6. At the end of TP1, 90.4% (75/83) of pts achieved JIA ACR 30 and 69.9% (58/83) achieved JIA ACR 70. There were 21 and 10 flares in TP2, respectively in PBO and SEC treated pts with a significantly longer time to flare and 72% risk of flare reduction in SEC treatment vs PBO (HR: 0.28; 95% CI: 0.13–0.63; P<0.001) (Figure 1). JIA ACR responses, disease activity and enthesitis count are reported in Table 1. NRI analyses showed that 87.2%, 83.7%, 67.4%, 38.4% and 24.4% of pts achieved JIA ACR 30/50/70/90/100, respectively. Rates of adverse events (AEs; 91.7% vs 92.1%) and serious AEs (14.6% vs 10.5%) in SEC and PBO groups were comparable in the entire TP. No new safety signals were observed.

POS0075 SAFETY AND EFFICACY OF GOLIMUMAB FOR THE TREATMENT OF POLYARTICULAR JUVENILE IDIOPATHIC ARTHRITIS - AN UPDATE FROM THE BIKER REGISTRY

Background:

Golimumab (GOL) is approved for treatment of polyarticular juvenile idiopathic arthritis (pJIA) in patients 2 years and older. Data on long-term safety of GOL in this indication are limited.

Objectives:

To assess long-term safety and efficacy of GOL in pJIA patients.

Methods:

In this ongoing non-interventional observational study, clinical characteristics, disease activity and safety parameters were analysed using the German Biologics in Paediatric Rheumatology (BiKeR) registry. 81 pJIA-patients treated with GOL were body weight-matched with 162 patients receiving alt. tumor necrosis factor inhibitors (TNFi) and 81 biologic–naïve patients under methotrexate (MTX)-therapy.

Results:

Baseline parameters of GOL patients differed from the alternative TNFi and MTX cohorts. In patients starting with GOL treatment, disease duration was longer, corticosteroid use was less and disease activity, measured by the mean number of active joints and the JADAS10, was lower (Table 1).

The long-term clinical efficacy of GOL in pJIA is highlighted by a decrease of the mean JADAS 10 from 11.6 (baseline) to 5.2 after 24 months. After 2 years, a JADAS 10 minimal disease activity was reached by 44.4 % of patients, whereas 22.2 % of patients were in remission and the JIA ACR 30/50/70/90 response rates were 77.8/72.2/66.7/55.6% respectively.

AE, SAE and infectious AE rates between the three cohorts were comparable (Table 1). In the GOL cohort, 4 SAE (1 uveitis, 1 arthritis flare, 1 fibromyalgia syndrome and 1 abscess) were reported, while in the alt. TNFi group 7 SAEs and in the MTX cohort 1 SAE were noted (Table 1). One serious infectious event (1 abscess) was documented in the GOL cohort, 2 alt. TNFi patients had influenza and no serious infectious events were seen in the MTX control group.

Few autoimmune processes occurred: 2 incident events in the GOL cohort (1 uveitis, 1 psoriasis), 3 cases in the alt. TNFi group (2 uveitis, 1 psoriasis,) and 1 event in MTX-patients (celiac disease) (Table 1). Out of the 20 GOL patients with preexisting uveitis at baseline, 6 had flare events; there were no reported uveitis flares of the 17 patients in the alt. TNFi group and no patients with preexisting uveitis in the MTX-group. No malignancies or deaths were reported.

Conclusion:

Our interim results show an acceptable safety profile of GOL therapy, comparable to treatment with alt. TNFi or MTX. No new safety signals occurred. The efficacy outcome data confirm long-term benefits of GOL treatment in pJIA patients.

POS1379 LONG-TERM EFFICACY AND SAFETY OF CANAKINUMAB IN PATIENTS WITH FAMILIAL MEDITERRANEAN FEVER (FMF) - INTERIM ANALYSIS OF THE RELIANCE REGISTRY

Background:

Familial Mediterranean Fever (FMF) is characterized by recurrent attacks of fever and serositis as well as elevated inflammatory markers. FMF treatment goals according to EULAR are to control acute attacks and subclinical inflammation and to improve patients´ quality of life1. In a phase 3 pivotal study (CLUSTER study), FMF patients treated with the interleukin-1β inhibitor canakinumab met all these goals2.

Objectives:

The present study explores the long-term efficacy and safety of canakinumab (CAN) in routine clinical practice in pediatric (age ≥2 years) and adult FMF patients.

Methods:

RELIANCE is a prospective, non-interventional, multi-center, observational study based in Germany with a three-year follow-up period. Patients with clinically confirmed diagnosis of FMF who routinely receive CAN were enrolled in order to evaluate effectiveness and safety of CAN under standard clinical practice conditions. Disease activity and remission by physicians´ assessment, disease activity, fatigue and impact on social life by patients’ assessment, inflammatory markers and AIDAI (Auto-Inflammatory Diseases Activity Index) score were recorded at baseline and were assessed at 6-monthly intervals within the three-year observation period of the study.

Results:

This interim analysis of FMF patients (N=54) enrolled by December 2020 includes baseline as well as 6-, 12- and 18-month data. Mean age in this cohort was 25 years (4−56 years) and the proportion of female patients was 46 % (N=25). At baseline, median duration of prior CAN treatment was 2.0 years (0−6 years).

While physician ratings report around 62% of patients in disease remission, 52% with absent and 34% with mild-moderate disease activity, patient-reported disease activity decreased from moderate (PPA 3.0) to low (PPA 2.0) during the observation period. A decrease was observed regarding disease activity parameters, in particular in patients without prior CAN therapy (Table 1, Figure 1). A total of 11 serious adverse events was reported, of which one case of tonsillectomy was classified as drug-related.

Conclusion:

Interim data of FMF patients from the RELIANCE study, the longest running real-life CAN registry, confirm efficacy and safety of long-term CAN treatment.

SAT0502 LONG-TERM OBSERVATIONAL SAFETY SURVEILLANCE OF GOLIMUMAB TREATMENT FOR POLYARTICULAR JUVENILE IDIOPATHIC ARTHIRTIS—AN INTERIM ANALYSIS

Background:

Golimumab (GOL) is approved for treatment of polyarticular juvenile idiopathic arthritis (pJIA) in patients 2 years and older. Data on long-term safety in this indication are limited.

Objectives:

Prospective monitoring of long-term safety and effectiveness of GOL in routine care using the German BIKER registry.

Methods:

In this non-interventional study baseline and safety parameters were compared between patients initiating GOL and contemporary matched control cohorts starting either an alternative TNF inhibitor (TNFi) or methotrexate (MTX) without exposure to a biologic. Efficacy outcomes were JADAS10, JIA ACR scores, joint counts and Childhood Health Assessment Questionnaire disability-index (CHAQ-DI). Safety assessments were based on adverse event (AE) reports.

Results:

From 2016 to 2019, 55 patients initiating GOL have been recruited and matched to 110 patients starting alternative TNFi and 47 biologic-naïve patients. Patients starting GOL had a longer disease duration (6.8y vs. 4.1 y and 1.0y; p<0.0001) and use of GOL was significantly more often second-line (85% vs 31% and 0%, p<0.0001). Disease activity was lower at baseline compared to MTX patients as indicated by active joint counts, JADAS10 and concomitant steroid use. Otherwise they were comparable with patients treated with other TNFi (Table 1).

In GOL treated patients a marked clinical response was noted at 6 months and beyond demonstrated by a significant decrease of the mean JADAS 10 from 11.3 to 6.4 (p=0.0008), as well as JIA ACR 30/50/70/90 response rates of 56/56/35/21%. JADAS remission and minimal disease activity was observed in 18% and 47% after 6 months and in 29% and 43% of patients after 12 months.

Rates of AE, SAE and infectious AE were comparable between the GOL cohort (96, 4.2 and 12.8/100PY), the alternative TNFi cohort (114, 5.4 and 11.8/100PY) and the MTX cohort (107, 2.7 and 24.5/100PY). SAE reported in the GOL cohort were uveitis and JIA flare (each 1). Two serious infections, both influenza, were reported in the alternative TNFi cohort, none in the GOL cohort. No case of pregnancy, malignancy or death was reported.

Conclusion:

Interim results from this ongoing safety surveillance study indicate acceptable safety and tolerability of GOL in pJIA that is comparable to treatment with alternative TNFi or MTX. The long-term effectiveness data reinforce the established efficacy of GOL in pJIA treatment.

SAT0490 MATCHED CONTROLLED SURVEILLANCE OF TOCILIZUMAB TREATMENT FOR POLYARTICULAR JUVENILE IDIOPATHIC ARTHRITIS–AN INTERIM ANALYSIS

Background:

Tocilizumab (TOC) is approved for treatment of polyarticular juvenile idiopathic arthritis (pJIA). Data out of clinical practice are limited.

Objectives:

Long-term surveillance of patients initiating TOC treatment compared to a cohort of patients initiating a comparator biologic using the BIKER-registry.

Methods:

Baseline parameters, efficacy and safety parameters were compared. Efficacy outcomes were JADAS10 and joint counts. Functional status was determined with the Childhood Health Assessment Questionnaire disability-index (CHAQ-DI). Safety was assessed by adverse events (AE) reports.

Results:

Until January 2020, 152 patients have been recruited to each cohort. Patients starting on TOC were older at treatment start (12.1 vs. 10.1 years (y); p<0.0001) and had a longer disease duration (5.4y vs. 3.0y; p<0.0001). TOC was significantly more often a second-line biologic (84% vs 13%, p< 0.0001). Otherwise patients were comparable (Table 1).

Upon TOC a substantial response to treatment with a significant reduction in JADAS 10 from 16.8 to 3.4 (p<0.0001) after 12 months was observed. There were no significant differences between patients from the TOC cohort and their matched controls regarding JIA ACR 30/50/70/90 criteria and active joint counts. JADAS 10, JADAS remission (REM) and minimal disease activity (MDA) was reached by comparable numbers in the TOC (37% and 58%) and the control cohort (37% and 60%).

While the total number of AE was comparable between the TOC cohort (58/100PY) and in the control cohort (54/100PY; RR 1.1; 95%CI 0.9-1.4), more serious AE (SAE) were reported with TOC (4.8/100PY compared to 1.4/100PY; RR 3.5; 95% CI 1-10.9). Medically important infections and uveitis events were documented at significantly lower frequency in the TOC- (0.8/100PY) than in the control cohort (4.1/100PY; RR 0.2; 95% CI 0.04-0.9). SAE with TOC were suicidal intent (n=3), depression (n=2), exacerbation of JIA, abscess, gastrointestinal infection, abdominal pain, colitis, bone surgery and fracture (n=1). SAE in the control cohort were depression, osteomyelitis, gastrointestinal infection and superinfected eczema (n=1). No significant differences regarding cytopenia and elevated transaminases were observed. No gastrointestinal perforation, no vascular event, no malignancy and no death occurred.

Conclusion:

The efficacy of tocilizumab is comparable to that of alternative biologics. Tolerability was acceptable. As Tocilizumab was given as a second-line biologic in the vast majority of patients, comparisons between the cohorts have to be interpreted carefully. Observation in the registry is ongoing.

THU0515 SYSTEMIC LUPUS ERYTHEMATOSUS IN CHILDHOOD AND ADOLESCENCE - UPDATE FROM THE NATIONAL PEDIATRIC RHEUMATOLOGY DATABASE

Background:

Systemic lupus erythematosus (SLE) is a clinically heterogeneous disease, which begins in childhood and adolescence in 15 - 20% of cases. Since 2004, data on SLE have been collected by means of a disease-specific questionnaire as part of the National pediatric rheumatology database (NPRD) in Germany. Since 2014, kidney biopsy results have been recorded to further specify kidney involvement.

Objectives:

Evaluation of clinical signs and symptoms, outcome and laboratory data of patients with juvenile systemic lupus erythematosus from a large database in Germany.

Methods:

Data from patients with SLE recorded in the NPRD in 2017 were considered for the analysis. In addition to age, sex, onset of disease, the criteria that led to the diagnosis, various laboratory parameters, organ involvement (current, ever) and therapy (current, last 12 months), current disease activity (numerical rating scale 0-10, NRS) and ECLAM (score 0-10) were recorded. Patient-reported outcomes included global assessments of overall-wellbeing and fatigue (NRS 0-10) and functional ability (CHAQ).

Results:

196 patients (86% female) with a median age of 16 years were documented. Criteria most frequently met at diagnosis included “antinuclear antibodies” (88%), followed by “anti-ds-DNA-Ab” (66%), “butterfly erythema” (42%) and “arthritis” (41%). A positive family history was found in 10% of patients.

At documentation, 85% of patients received disease-modifying anti-rheumatic drugs, most frequently hydroxychloroquine (73%), followed by mycophenolate mofetil (32%) and azathioprine (17%). Systemic glucocorticoids obtained 52% of patients, 12% ≥ 0.2 mg/kg/day. Biologics (rituximab 2%) and cyclophosphamide i.v. (3%) were rarely administered during the last 12 months. Disease activity was reported as 1.0 (NRS, median, IQR 0 - 9), ECLAM as 1.0 (median, range 0 - 10). In the laboratory, leukopenia < 3500/µl was found in 9% of patients, lymphopenia < 1500/µl in 47% and erythrocyte sedimentation rate (ESR) > 25 mm in 15% of patients. Mean CHAQ was 0.24, and 86% of patients had a CHAQ score < 0.5. Mean patient`s global assessment of overall-wellbeing was 1.5, while the mean fatigue score was 2.86 (18% NRS score 7-10).

The following organ involvement was ever present: general symptoms 84%, skin/mucosa 72%, joints 73%, thyroid 15%, muscle 25%, lungs 17% and CNS 30%. In 45/190 (24%) patients, a kidney involvement was stated. In 34 patients (75%) a kidney biopsy was performed and histology yielded the following results: Class 1: 6.7%, Class 2: 16.7%, Class 3: 40.0%, Class 4: 23.3%, Class 5: 13.3%.

Conclusion:

The most common clinical symptoms documented in juvenile SLE patients were skin and joint involvement. In the course of the disease, a quarter of the patients developed kidney involvement, mostly proliferative nephritis. Apparently, azathioprine is increasingly being replaced by mycophenolate mofetil, biologicals have hardly been used so far. Although functional outcome and overall-wellbeing of jSLE patients was good, fatigue was a concern for some patients.

Diagnosis and treatment of Guillain-Barré Syndrome in childhood and adolescence: An evidence- and consensus-based guideline

This evidence- and consensus-based practical guideline for the diagnosis and treatment of Guillain-Barré Syndrome (GBS) in childhood and adolescence has been developed by a group of delegates from relevant specialist societies and organisations; it is the result of an initiative by the German-Speaking Society of Neuropediatrics (GNP), and is supported by the Association of Scientific Medical Societies (AWMF, Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften). A systematic analysis of the literature revealed that only a few adequately-controlled studies exist for this particular age group, while none carries a low risk of bias. For this reason, the diagnostic and therapeutic recommendations largely rely on findings in adult patients with GBS, for which there are a higher number of suitable studies available. Consensus was established using a written, multi-step Delphi process. A high level of consensus could be reached for the crucial steps in diagnosis and treatment. We recommend basing the diagnostic approach on the clinical criteria of GBS and deriving support from CSF and electrophysiological findings. Repetition of invasive procedures that yield ambiguous results is only recommended if the diagnosis cannot be ascertained from the other criteria. For severe or persistently-progressive GBS treatment with intravenous immunoglobulin (IVIG) is recommended, whereas in cases of IVIG intolerance or inefficacy we recommended treatment with plasmapheresis. Corticosteroids are ineffective for GBS but can be considered when acute onset chronic inflammatory demyelinating polyneuropathy (A-CIDP) is suspected due to a prolonged disease course. The full German version of the Guideline is available on the AWMF website (https://www.awmf.org/leitlinien/detail/ll/022-008.html).

Breastfeeding and vitamin D supplementation reduce the risk of Kawasaki disease in a German population-based case-control study

Background

In Kawasaki disease (KD), a vasculitis of unknown etiology, the most serious complication is the development of coronary artery aneurysm (CAA). To date, the exact pathomechanism of KD is unknown. Both environmental and genetic factors seem to be associated with the development of the disease.

Methods

Data on KD patients recruited from the population-based German Pediatric Surveillance Study during 2012–2014 were used to evaluate the impact of various factors from the perinatal and infancy period on the development of KD. The study design was a matched case-control study with respect to age, sex and place of residence (n = 308 KD cases, n = 326 controls). All KD patients were individually re-evaluated; all fulfilled the international diagnostic KD criteria. A standardized questionnaire was used to review breastfeeding practices, vitamin D supplementation and birth characteristics. Logistic regression analyses were performed to obtain odds ratios (OR) for various risk factors among the case-control pairs. Simple measures of association were used to assess the impact of these factors on the clinical course.

Results

There was no difference in lengths of gestation, birth weight or parturition between KD patients and controls, but independently from each other vitamin D supplementation and breastfeeding were negatively associated with KD, even when adjusted for age, place of residence and sex. The duration of vitamin D was significantly shorter among children with KD than among children without KD (p = 0.039, OR = 0.964, 95% CI: 0.931–0.998), as was the duration of breastfeeding (p = 0.013, OR = 0.471, 95% CI: 0.260–0.853). Comparing KD patients with and without breastfeeding and/or vitamin D supplementation, there were no differences regarding developing CAA, being refractory to intravenous immunoglobulin treatment, age at onset of the disease and levels of inflammatory laboratory values.

Conclusion

Our findings indicate breastfeeding and vitamin D supplementation to have protective effects in association with KD in our study population; however, these seem not to influence the natural course of the disease. Although the overall effects were relatively small, they nevertheless underline the overall benefit of both interventions.

Abstract P1-13-01: Final results of the ASG1-3 study, a randomized phase III study comparing a standard dose chemotherapy with epirubicin/cyclophosphamide and paclitaxel with a dose dense regimen with epirubicin and paclitaxel

Background

Dose dense chemotherapy (DDT) has shown improvements of disease-free survival (DFS) and overall survival for primary breast cancer patients with a high risk of relapse. There are much less data about the effect of DDT in patients with intermediate risk of recurrence (1-3 positive axillary lymph nodes). Aim of this prospectively randomized trial was to investigate the superiority of a DDT schedule over a standard chemotherapy (ST) in primary breast cancer patients with 1-3 positive axillary lymph nodes.

Methods

The ASG1-3 study is a prospectively randomized, open label phase III study of the Adjuvant Study Group of the NOGGO association. Patients were eligible for the trial, if they had a primary invasive breast cancer (pT1-3) with 1-3 positive axillary lymph nodes and no evidence of distant metastases. Patients were randomized to an adjuvant therapy with either 4 cycles epirubicin (90mg/m2 body surface area, BSA) and cyclophosphamide (600mg/m2 BSA) q3w, followed by 4 cycles of paclitaxel (175mg/m2 BSA) referred to as ST or to a therapy with 4 cycles of epicubicin (120 mg/m2 BSA) q2w and primary G-CSF support followed by 4 cycles of paclitaxel (175mg/m2 BSA) q2w and primary G-CSF support referred to as DDT. Trastuzumab was not given in this study. The study was designed to show an increase of 70% DFS (ST) to 80% DFS (DDT) 5 years after randomization. Comparisons were conducted using Kaplan Meier estimates, log rank tests and Cox regression analyses. In an exploratory way, subgroup analyses were performed for HER2, hormone receptor status and grading using Cox regression models with interaction terms.

Results

A total of 936 patients were eligible for survival analysis, of which 465 were randomized to ST and 471 to DDT from 2001 to 2004. Patient characteristics were mainly well balanced, with patients being 52.5/52.1 years old, 71.9/78.1% being hormone receptor positive, 24.4/24.6% being HER2 positive and 38.6/38.8% having a tumor grade of 3 in the ST arm and DDT arm respectively. 53 events occurred after ST and 46 after DDT. Adjusted hazard ratio (HR) was 0.87 (95%CI: 0.57-1.35; p=0.54). 5 year DFS rates were 85% (ST) vs. 87% (DDT). Hematological toxicities were the most common grade 3 or 4 adverse events. Grade 3/4 neutropenia occurred in 57.2 vs. 28.0%, grade 3/4 anemia in 15.3% vs. 17.1% and grade 3 /4 pain symptoms were seen in 13.2 vs. 12.4% of the patients in the ST arm vs. DDT arm respectively. Other grade 3/4 toxicities were less frequent than 10%. Subgroup analysis showed a significant interaction (p&lt;0.001) between HER2 status and randomization arm with regard to DFS. In HER2 negative patients the HR was 1.53 (95%CI: 0.91-2.59), whereas in HER2 positive patients the HR was 0.22 (95%CI: 0.09-0.55). Patients with HER2 positive disease and DDT had a similar prognosis like HER2 negative patients.

Conclusion

In the overall population a statistically significant improvement of DFS could not be shown for the DDT arm. In patients with HER2 positive breast cancer DDT chemotherapy improved the disease-free survival to a prognosis which was similar to patients with HER2 negative disease.

Cardiac thrombus with risk of fulminant pulmonary embolism in paediatric antiphospholipid syndrome

Antiphospholipid Syndrome (APS) describes a systemic disease caused by autoantibodies to membrane components. Involving coagulation pathways, complement factors and immune cells, it results in thrombosis in any blood vessel. Its clinical presentation varies considerably depending upon the organ affected. Paediatric data on APS remain sparse. Most case reports focus on catastrophic APS with multiple small-vessel occlusions and a life-threatening course. Here, we report on a 15-year-old patient with deep vein thrombosis and a right ventricular tumour posing the risk of a fulminant pulmonary embolism. The tumour was surgically removed. Histology revealed it to be a thrombus. The patient fully recovered and is currently treated with long term anticoagulation.

Primary cutaneous cryptococcosis in an eight-year-old immunocompetent child: how to treat?

Here we report on a case of primary cryptococcal skin infection in an immunocompetent 8-year-old boy. The infection first manifested itself as a subcutaneous abscess around the proximal joint of his right thumb after a minor injury from contact with a thorny shrub. After surgical incision and drainage was performed, Cryptococcus neoformans var. neoformans was the only pathogen cultured from the lesion. An agglutination test for the capsular antigen in serum displayed negative results and the immunological work-up revealed no underlying immunodeficiency. A "watch and wait" strategy - one without systemic antifungal treatment - was adopted and this resulted in uneventful healing. In summary, primary cryptococcal skin infections in immunocompetent hosts may be managed successfully by surgical treatment in combination with careful clinical follow-up. This approach may help avoid unnecessary antimicrobial treatments.

Prevention of group B streptococcal neonatal disease revisited. The DEVANI European project

The purpose of this paper was to present the current knowledge on the prevention of group B streptococcus (GBS) neonatal infections and the status of prevention policies in European countries and to present the DEVANI pan-European program, launched in 2008. The aim of this program was to assess the GBS neonatal infection burden in Europe, to design a new vaccine to immunize neonates against GBS infections, to improve the laboratory performance for the diagnosis of GBS colonization and infection, and to improve the methods for the typing of GBS strains. The current guidelines for GBS prevention in different countries were ascertained and a picture of the burden before and after the instauration of prevention policies has been drawn. After the issue of the Centers for Disease Control and Prevention (CDC) guidelines, many European countries have adopted universal screening for the GBS colonization of pregnant women and intrapartum prophylaxis to colonized mothers. Nevertheless, some European countries continue advocating the risk factor approach to GBS prevention. Most European countries have implemented policies to prevent GBS neonatal infections and the burden of the disease has decreased during the last several years. Nevertheless, further steps are necessary in order to develop new strategies of prevention, to improve microbiological techniques to detect GBS colonization and infection, and to coordinate the prevention policies in the EU.

[The pain situation for residents of nursing homes. Results of a study in Münster]

BACKGROUND

Little is known about the phenomenon of pain in German nursing homes. In particular, it is unknown to what extent and severity pain occurs among residents and how their pain can be described.

MATERIAL AND METHODS

A total of 13 nursing homes located in the city of Münster, Germany, were included as part of the health services research project "Action Alliance Pain-free City Münster." Data were collected from 436 residents over 65 years old via self-report or the observational pain tool pain assessment in advanced dementia, german version (PAINAD-G), according to the cognitive status of the residents.

RESULTS

At the time of the interview, the majority of the residents questioned reported suffering from pain at rest and/or during movement. Approximately one quarter of residents complained about moderate to intolerable pain at rest and nearly 45% during movement. Residents encountered pain most often when standing up, sitting, resting in bed and walking and three quarters of residents had suffered from pain for more than 1 year. Many residents experienced pain in several body regions. Among residents assessed solely by the observational pain scale PAINAD-G, signs indicating pain existed in 21% (≥ 6) or 69% (≥ 2), respectively, depending on the cut-off value chosen on the PAINAD-G scale.

CONCLUSION

Pain in nursing homes is a challenge that needs more attention as it has considerable negative consequences for the persons concerned. The extent of pain in the studied facilities indicates an urgent need for action on the part of all professionals caring for residents in nursing homes.

[Hemorrhagic skin lesions associated with infections]

Eine Vielzahl von bakteriellen, viralen oder parasitären Infektionserkrankungen kann mit hämorrhagischen Effloreszenzen einhergehen. Die Symptomkonstellation Fieber und Petechien kann Vorbote einer fulminanten bakteriellen Sepsis sein, die einer sofortigen intensiven Therapie zugeführt werden muss. Viel häufiger liegt der Symptomatik aber ein harmloser selbstlimitierender Virusinfekt zugrund, sodass man in Bezug auf das Ausmaß der notwendigen Diagnostik vor einem Dilemma steht. Der vorliegende Beitrag gibt eine Übersicht über die Differenzialdiagnosen und Pathophysiologie infektionsassoziierter Hautblutungen, und es wird ein differenzialdiagnostischer Algorithmus für die Diagnosefindung bei der Konstellation Fieber plus Petechien vorgeschlagen.

[Japanese encephalitis: risk for endemic populations and for travellers]

The importance of Japanese encephalitis (JE) in endemic populations and in travellers requires a balanced assessment. This disease represents an important public health problem in some endemic areas, which contrasts with the minimal risk for travellers to endemic areas. This is reflected by high numbers of infections mainly among children in endemic countries and by few case reports among tourists and even expatriates. The total number of case reports between 1978 and 2008 amounts to a risk of one to two cases per year. Nevertheless, some travelling groups may be at higher risk when visiting or working in high risk areas. A new vaccine against Japanese encephalitis will soon be registered in Switzerland. This paper contributes to the scarce data available for decision making whether or not to recommend the vaccination to tourists and expatriates.

[Differential diagnosis of neurodegenerative disorders in young adults]

Neurodegenerative diseases are relatively common and usually occur in older patients. In young adulthood, neurodegeneration is less common and more frequent due to underlying inborn errors of metabolism (IEMs) that typically have a wide range of clinical presentations. In the following overview, we present a case of SSPE and NBIA. The main differential diagnoses, cardinal symptoms, diagnosis and treatment options of neurodegenerative-like disesase in young adults are presented.

[Successful continuous renal replacement therapy in a neonate with early-onset group B streptococcal sepsis and multi-organ dysfunction syndrome]

BACKGROUND

Group B streptococcal early-onset sepsis (GBS EOS) in neonates has a mortality rate of approximately 5%, particularly in the presence of multi-organ dysfunction. Fluid management is crucial in these patients, and continuous venovenous haemofiltration (CVVH) should be considered a therapeutic option even in newborn babies.

CASE REPORT

After an uneventful pregnancy within hours after birth, a female term infant presented with dyspnoea, irritability and cyanosis. The systemic inflammatory response syndrome (SIRS) progressed to multi-organ dysfunction with acute respiratory distress syndrome (ARDS), impaired myocardial contractility, pulmonary hypertension and fluid overload. The maximum PRISM score was 51. The child required maximal respiratory and inotropic support with high volume intravenous fluid administration. However, only by using of CVVH from day 5 to 14, we successfully resolved progressive pulmonary and cardiovascular dysfunction. The child improved directly after initiation of fluid removal, was extubated on day 17 and discharged without obvious sequelae on day 57. All microbiology studies revealed GBS.

CONCLUSION

Perinatal GBS-infections remain a major life-threatening event for newborn babies. CVVH should be considered an option for reversing fluid overload even in neonates with overwhelming SIRS. Alternatively, extracorporeal membrane oxygenation (ECMO) is discussed.

Distribution of four capsular serotypes of Enterococcus faecalis among clinical isolates from different geographical origins and infection sites

BACKGROUND

Enterococci possess capsular polysaccharide antigens that are the targets of opsonic antibodies. These antibodies are potential candidates for development as immunotherapy.

MATERIAL AND METHODS

The present study analyzes the distribution of four capsular serotypes within a collection of 157 isolates of Enterococcus faecalis from four countries with different sites of clinical infection.

RESULTS

By using a capsular polysaccharide-specific ELISA, 42% of the isolates were grouped into one of four serogroups, and another 9% showed cross-reactivity between two serotype-specific sera. Heterogeneity of serotype distribution by both geographical origin and infection site was observed.

CONCLUSION

Half of the strain collection could be typed with four serotype-specific sera. No serotype from a given country or infection site clearly predominated.

Analysis of the Specific Immune Response against Capsular Polysaccharides of Two Patients with Systemic Enterococcal Infections

Systemic enterococcal infections often lead to life-threatening disease. By analyzing the immune response of two patients with systemic enterococcal infections against enterococcal polysaccharide antigens, we found that both patients had antibodies against all four of the capsular serotypes identified to date. Antibody concentrations against the causative capsular serotype were in the same range as antibodies against the other three capsular protoserotypes. Interestingly, we noted a difference between the two patients with respect to opsonic activity in the killing assay: one patient showed better killing of all four capsular prototypes than the other. However, killing against the infecting serotype was not increased in comparison to killing of the other serotypes in the two patients. This finding supports previously published data that most healthy humans possess preexisting, naturally acquired, anti-enterococcal antibodies. We conclude, therefore, that systemic infection with enterococci does not lead to higher antibody concentrations or better opsonic killing against the causative capsular serotype.

In vitro Assessment of the Host Response against Enterococcus faecalis Used in Probiotic Preparations

Along with other lactic acid bacteria, enterococci are used in food products and as health promoting agents. The safety of these products must be ensured, because they contain potentially pathogenic microorganisms. Here we present an in vitro opsonophagocytic assay that closely mimics the protective human immune response to Enterococcus faecalis and Enterococcus faecium. A collection of closely related E. faecalis isolates used as probiotics showed different susceptibilities to opsonic killing, suggesting that some of these isolates possess a capsule while other do not. This information may be helpful in assessing the safety of a given bacterial isolate used and could detect likely enterococcal candidates for probiotic preparations.

Rapid molecular discrimination between infection with wild-type varicella-zoster virus and varicella vaccine virus

Varicella-zoster virus (VZV) infection is immunocompromised patients may cause life-threatening complications. Prevention measures include administration of VZV immuloglobulin, acyclovir and live attenuated varicella vaccine. After vaccination, a mild varicella-like exanthem appears in up to 5% of vaccinees. Morphologically this exanthem cannot be differentiated from wild-type (wt) varicella. The risk of virus transmission after varicella vaccination, in contrast to wt varicella, is low, even in immunocompromised patients. We report on a 2-year-old girl with relapse of cereral anaplastic ependymoma, who received one dose of varicella vaccine. Two weeks later, a maculopapular rash developed while she was an inpatient on the oncology ward. Using VZV-specific PCR and restriction fragment length polymorphism (RFLP) analysis, we were able to diagnose wt varicella infection. Thus, appropriate prevention measures (VZV immunoglobulin and acyclovir) were justified for close contacts to prevent virus transmission. No secondary cases occurred.
