Despite current recommendations that infants with history of prematurity/LBW should receive routine immunization according to the same schedule and chronological age as full-term infants, immunization is often delayed. Methods Here we summarize 10 clinical studies and 15 years of post-marketing safety surveillance of GSK's hexavalent vaccine (DTPa-HBV-IPV/Hib), a combined diphtheria-tetanus-acellular-pertussis-hepatitis-B-inactivated-poliovirus-Haemophilus influenzae-type-b (Hib) conjugate vaccine, when administered alone, or co-administered with pneumococcal conjugate, rotavirus, and meningococcal vaccines and respiratory syncytial virus IgG to infants with history of prematurity/LBW in clinical trials. Results At least 92.5\% of infants with history of prematurity/LBW as young as 24 weeks gestation in clinical studies were seropositive to all vaccine antigens after 3-dose primary vaccination with GSK's hexavalent DTPa-HBV-IPV/Hib vaccine, with robust immune responses to booster vaccination. Seropositivity rates and antibody concentrations to hepatitis B and Hib appeared lower in infants with history of prematurity/LBW than term infants. Between 13-30\% of medically stable infants with history of prematurity developed apnea after vaccination with GSK's hexavalent DTPa-HBV-IPV/Hib vaccine; usually after dose 1. The occurrence of post-immunization cardiorespiratory events appears to be influenced by the severity of any underlying neonatal condition. Most cardiorespiratory events resolve spontaneously or require minimal intervention. GSK's hexavalent DTPa-HBV-IPV/Hib vaccine was well tolerated in co-administration regimens. Conclusion GSK's hexavalent DTPa-HBV-IPV/Hib vaccine alone or co-administered with other pediatric vaccines has a clinically acceptable safety and immunogenicity profile when used in infants with history of prematurity/LBW for primary and booster vaccination. Additional studies are needed in very premature and very LBW infants. However, currently available data support using GSK's hexavalent DTPa-HBV-IPV/Hib vaccine to immunize infants with history of prematurity/LBW according to chronological age.}, language = {en} } @article{SpadaBaronElliottetal.2019, author = {Spada, Marco and Baron, Ralf and Elliott, Perry M. and Falissard, Bruno and Hilz, Max J. and Monserrat, Lorenzo and T{\o}ndel, Camilla and Tylki-Szymańska, Anna and Wanner, Christoph and Germain, Dominique P.}, title = {The effect of enzyme replacement therapy on clinical outcomes in paediatric patients with Fabry disease - A systematic literature review by a European panel of experts}, series = {Molecular Genetics and Metabolism}, volume = {126}, journal = {Molecular Genetics and Metabolism}, doi = {10.1016/j.ymgme.2018.04.007}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-239287}, pages = {212-223}, year = {2019}, abstract = {Background Fabry disease is caused by a deficiency of the lysosomal enzyme α-galactosidase, resulting in progressive accumulation of globotriaosylceramide (GL-3). The disease can manifest early during childhood and adolescence. Enzyme replacement therapy (ERT) with recombinant human α-galactosidase is the first specific treatment for Fabry disease and has been available in Europe since 2001. This paper presents the findings of a systematic literature review of clinical outcomes with ERT in paediatric patients with Fabry disease. Methods A comprehensive systematic review of published literature on ERT in Fabry disease was conducted in January 2017. The literature analysis included all original articles reporting outcomes of ERT in paediatric patients. Results Treatment-related outcomes in the paediatric population were reported in six publications derived from open-label clinical trials and in 10 publications derived from observational or registry-based studies. ERT was shown to significantly reduce plasma and urine GL-3 levels in paediatric patients with Fabry disease. The effect of ERT on GL-3 clearance from renal podocytes appeared to be agalsidase dose-dependent. ERT relieved pain and improved gastrointestinal symptoms and quality of life. Conclusions Based on the published literature, the use of ERT in paediatric patients can significantly clear GL-3 accumulation, ameliorate the early symptoms of Fabry disease, and improve quality of life. Treatment with ERT in paediatric patients with Fabry disease may be important to prevent further disease progression and overt organ damage.}, language = {en} } @article{ArgyrousideNijsLagattaetal.2019, author = {Argyrousi, Elentina K. and de Nijs, Laurence and Lagatta, Davi C. and Schl{\"u}tter, Anna and Weidner, Magdalena T. and Z{\"o}ller, Johanna and van Goethem, Nick P. and Joca, S{\^a}mia R.

Moreover, several studies have shown that DNA methylation is able to affect the expression of (e.g. plasticity) genes that are important for several cognitive functions. In this study, the effect of the DNA methyltransferase (DNMT) inhibitor RG108 was assessed on object pattern separation (OPS) task in mice. In addition, its effect on the expression of target genes was monitored. Administration of RG108 before the test led to a short-lasting, dose-dependent increase in pattern separation memory that was not present anymore after 48 h. Furthermore, treatment with RG108 did not enhance long-term memory of the animals when tested after a 24 h inter-trial interval in the same task. At the transcriptomic level, acute treatment with RG108 was accompanied by increased expression of Bdnf1, while expression of Bdnf4, Bdnf9, Gria1 and Hdac2 was not altered within 1 h after treatment. Methylation analysis of 14 loci in the promoter region of Bdnf1 revealed a counterintuitive increase in the levels of DNA methylation at three CpG sites. Taken together, these results indicate that acute administration of RG108 has a short-lasting pro-cognitive effect on object pattern separation that could be explained by increased Bdnf1 expression. The observed increase in Bdnf1 methylation suggests a complex interplay between Bdnf methylation-demethylation that promotes Bdnf1 expression and associated cognitive performance. Considering that impaired pattern separation could constitute the underlying problem of a wide range of mental and cognitive disorders, pharmacological agents including DNA methylation inhibitors that improve pattern separation could be compelling targets for the treatment of these disorders. In that respect, future studies are needed in order to determine the effect of chronic administration of such agents.}, language = {en} } @article{GraystonCzannerElhaddetal.2019, author = {Grayston, Rebecca and Czanner, Gabriela and Elhadd, Kareim and Goebel, Andreas and Frank, Bernhard and {\"U}{\c{c}}eyler, Nurcan and Malik, Rayaz A and Alam, Uazman}, title = {A systematic review and meta-analysis of the prevalence of small fiber pathology in fibromyalgia: Implications for a new paradigm in fibromyalgia etiopathogenesis}, series = {Seminars in Arthritis and Rheumatism}, volume = {48}, journal = {Seminars in Arthritis and Rheumatism}, doi = {10.1016/j.semarthrit.2018.08.003}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-227566}, pages = {933-940}, year = {2019}, abstract = {Objectives Fibromyalgia is a condition which exhibits chronic widespread pain with neuropathic pain features and has a major impact on health-related quality of life. The pathophysiology remains unclear, however, there is increasing evidence for involvement of the peripheral nervous system with a high prevalence of small fiber pathology (SFP). The aim of this systematic literature review is to establish the prevalence of SFP in fibromyalgia. Methods An electronic literature search was performed using MEDLINE, EMBASE, PubMed, Web of Science, CINAHL and the Cochrane Library databases. Published full-text, English language articles that provide SFP prevalence data in studies of fibromyalgia of patients over 18years old were included. All articles were screened by two independent reviewers using a priori criteria. Methodological quality and risk of bias were evaluated using the critical appraisal tool by Munn et al. Overall and subgroup pooled prevalence were calculated by random-effects meta-analysis with 95\% CI. Results Database searches found 935 studies; 45 articles were screened of which 8 full text articles satisfied the inclusion criteria, providing data from 222 participants. The meta-analysis demonstrated the pooled prevalence of SFP in fibromyalgia is 49\% (95\% CI: 38-60\%) with a moderate degree of heterogeneity, (I2= 68\%). The prevalence estimate attained by a skin biopsy was 45\% (95\% CI: 32-59\%, I2= 70\%) and for corneal confocal microscopy it was 59\% (95\% CI: 40-78\%, I2= 51\%). Conclusion There is a high prevalence of SFP in fibromyalgia. This study provides compelling evidence of a distinct phenotype involving SFP in fibromyalgia.

A crucial clinical question is whether cerebral microbleeds indicate patients with recent ischaemic stroke or transient ischaemic attack in whom the rate of future intracranial haemorrhage is likely to exceed that of recurrent ischaemic stroke when treated with antithrombotic drugs. We therefore aimed to establish whether a large burden of cerebral microbleeds or particular anatomical patterns of cerebral microbleeds can identify ischaemic stroke or transient ischaemic attack patients at higher absolute risk of intracranial haemorrhage than ischaemic stroke. Methods We did a pooled analysis of individual patient data from cohort studies in adults with recent ischaemic stroke or transient ischaemic attack. Cohorts were eligible for inclusion if they prospectively recruited adult participants with ischaemic stroke or transient ischaemic attack; included at least 50 participants; collected data on stroke events over at least 3 months follow-up; used an appropriate MRI sequence that is sensitive to magnetic susceptibility; and documented the number and anatomical distribution of cerebral microbleeds reliably using consensus criteria and validated scales. Our prespecified primary outcomes were a composite of any symptomatic intracranial haemorrhage or ischaemic stroke, symptomatic intracranial haemorrhage, and symptomatic ischaemic stroke. We registered this study with the PROSPERO international prospective register of systematic reviews, number CRD42016036602. Findings Between Jan 1, 1996, and Dec 1, 2018, we identified 344 studies. After exclusions for ineligibility or declined requests for inclusion, 20 322 patients from 38 cohorts (over 35 225 patient-years of follow-up; median 1·34 years [IQR 0·19-2·44]) were included in our analyses. The adjusted hazard ratio [aHR] comparing patients with cerebral microbleeds to those without was 1·35 (95\% CI 1·20-1·50) for the composite outcome of intracranial haemorrhage and ischaemic stroke; 2·45 (1·82-3·29) for intracranial haemorrhage and 1·23 (1·08-1·40) for ischaemic stroke. The aHR increased with increasing cerebral microbleed burden for intracranial haemorrhage but this effect was less marked for ischaemic stroke (for five or more cerebral microbleeds, aHR 4·55 [95\% CI 3·08-6·72] for intracranial haemorrhage vs 1·47 [1·19-1·80] for ischaemic stroke; for ten or more cerebral microbleeds, aHR 5·52 [3·36-9·05] vs 1·43 [1·07-1·91]; and for ≥20 cerebral microbleeds, aHR 8·61 [4·69-15·81] vs 1·86 [1·23-2·82]). However, irrespective of cerebral microbleed anatomical distribution or burden, the rate of ischaemic stroke exceeded that of intracranial haemorrhage (for ten or more cerebral microbleeds, 64 ischaemic strokes [95\% CI 48-84] per 1000 patient-years vs 27 intracranial haemorrhages [17-41] per 1000 patient-years; and for ≥20 cerebral microbleeds, 73 ischaemic strokes [46-108] per 1000 patient-years vs 39 intracranial haemorrhages [21-67] per 1000 patient-years). Interpretation In patients with recent ischaemic stroke or transient ischaemic attack, cerebral microbleeds are associated with a greater relative hazard (aHR) for subsequent intracranial haemorrhage than for ischaemic stroke, but the absolute risk of ischaemic stroke is higher than that of intracranial haemorrhage, regardless of cerebral microbleed presence, antomical distribution, or burden.}, language = {en} } @article{WaszakNorthcottBuchhalteretal.2018, author = {Waszak, Sebastian M and Northcott, Paul A and Buchhalter, Ivo and Robinson, Giles W and Sutter, Christian and Groebner, Susanne and Grund, Kerstin B and Brugi{\`e}res, Laurence and Jones, David T W and Pajtler, Kristian W and Morrissy, A Sorana and Kool, Marcel and Sturm, Dominik and Chavez, Lukas and Ernst, Aurelie and Brabetz, Sebastian and Hain, Michael and Zichner, Thomas and Segura-Wang, Maia and Weischenfeldt, Joachim and Rausch, Tobias and Mardin, Balca R and Zhou, Xin and Baciu, Cristina and Lawerenz, Christian and Chan, Jennifer A and Varlet, Pascale and Guerrini-Rousseau, Lea and Fults, Daniel W and Grajkowska, Wiesława and Hauser, Peter and Jabado, Nada and Ra, Young-Shin and Zitterbart, Karel and Shringarpure, Suyash S and De La Vega, Francisco M and Bustamante, Carlos D and Ng, Ho-Keung and Perry, Arie and MacDonald, Tobey J and Driever, Pablo Hern{\´a}iz and Bendel, Anne E and Bowers, Daniel C and McCowage, Geoffrey and Chintagumpala, Murali M and Cohn, Richard and Hassall, Timothy and Fleischhack, Gudrun and Eggen, Tone and Wesenberg, Finn and Feychting, Maria and Lannering, Birgitta and Sch{\"u}z, Joachim and Johansen, Christoffer and Andersen, Tina V and R{\"o}{\"o}sli, Martin and Kuehni, Claudia E and Grotzer, Michael and Kjaerheim, Kristina and Monoranu, Camelia M and Archer, Tenley C and Duke, Elizabeth and Pomeroy, Scott L and Shelagh, Redmond and Frank, Stephan and Sumerauer, David and Scheurlen, Wolfram and Ryzhova, Marina V and Milde, Till and Kratz, Christian P and Samuel, David and Zhang, Jinghui and Solomon, David A and Marra, Marco and Eils, Roland and Bartram, Claus R and von Hoff, Katja and Rutkowksi, Stefan and Ramaswamy, Vijay and Gilbertson, Richard J and Korshunov, Andrey and Taylor, Michael D and Lichter, Peter and Malkin, David and Gajjar, Amar and Korbel, Jan O and Pfister, Stefan M}, title = {Spectrum and prevalence of genetic predisposition in medulloblastoma: a retrospective genetic study and prospective validation in a clinical trial cohort}, series = {The Lancet Oncology}, volume = {19}, journal = {The Lancet Oncology}, doi = {10.1016/S1470-2045(18)30242-0}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-233425}, pages = {785-798}, year = {2018}, abstract = {Background Medulloblastoma is associated with rare hereditary cancer predisposition syndromes; however, consensus medulloblastoma predisposition genes have not been defined and screening guidelines for genetic counselling and testing for paediatric patients are not available. We aimed to assess and define these genes to provide evidence for future screening guidelines. Methods In this international, multicentre study, we analysed patients with medulloblastoma from retrospective cohorts (International Cancer Genome Consortium [ICGC] PedBrain, Medulloblastoma Advanced Genomics International Consortium [MAGIC], and the CEFALO series) and from prospective cohorts from four clinical studies (SJMB03, SJMB12, SJYC07, and I-HIT-MED). Whole-genome sequences and exome sequences from blood and tumour samples were analysed for rare damaging germline mutations in cancer predisposition genes. DNA methylation profiling was done to determine consensus molecular subgroups: WNT (MBWNT), SHH (MBSHH), group 3 (MBGroup3), and group 4 (MBGroup4). Medulloblastoma predisposition genes were predicted on the basis of rare variant burden tests against controls without a cancer diagnosis from the Exome Aggregation Consortium (ExAC). Previously defined somatic mutational signatures were used to further classify medulloblastoma genomes into two groups, a clock-like group (signatures 1 and 5) and a homologous recombination repair deficiency-like group (signatures 3 and 8), and chromothripsis was investigated using previously established criteria. Progression-free survival and overall survival were modelled for patients with a genetic predisposition to medulloblastoma. Findings We included a total of 1022 patients with medulloblastoma from the retrospective cohorts (n=673) and the four prospective studies (n=349), from whom blood samples (n=1022) and tumour samples (n=800) were analysed for germline mutations in 110 cancer predisposition genes. In our rare variant burden analysis, we compared these against 53 105 sequenced controls from ExAC and identified APC, BRCA2, PALB2, PTCH1, SUFU, and TP53 as consensus medulloblastoma predisposition genes according to our rare variant burden analysis and estimated that germline mutations accounted for 6\% of medulloblastoma diagnoses in the retrospective cohort. The prevalence of genetic predispositions differed between molecular subgroups in the retrospective cohort and was highest for patients in the MBSHH subgroup (20\% in the retrospective cohort). These estimates were replicated in the prospective clinical cohort (germline mutations accounted for 5\% of medulloblastoma diagnoses, with the highest prevalence [14\%] in the MBSHH subgroup). Patients with germline APC mutations developed MBWNT and accounted for most (five [71\%] of seven) cases of MBWNT that had no somatic CTNNB1 exon 3 mutations. Patients with germline mutations in SUFU and PTCH1 mostly developed infant MBSHH. Germline TP53 mutations presented only in childhood patients in the MBSHH subgroup and explained more than half (eight [57\%] of 14) of all chromothripsis events in this subgroup. Germline mutations in PALB2 and BRCA2 were observed across the MBSHH, MBGroup3, and MBGroup4 molecular subgroups and were associated with mutational signatures typical of homologous recombination repair deficiency. In patients with a genetic predisposition to medulloblastoma, 5-year progression-free survival was 52\% (95\% CI 40-69) and 5-year overall survival was 65\% (95\% CI 52-81); these survival estimates differed significantly across patients with germline mutations in different medulloblastoma predisposition genes. Interpretation Genetic counselling and testing should be used as a standard-of-care procedure in patients with MBWNT and MBSHH because these patients have the highest prevalence of damaging germline mutations in known cancer predisposition genes.

Der in der Best{\"a}tigungsdiagnostik verwendete Kochsalzbelastungstest basiert dabei auf einem fehlenden Absinken der Aldosteronkonzentration im Testverlauf bei Patient:innen mit PA im Vergleich zu Patient:innen mit essentieller Hypertonie (EH). Die Konzentrationsbestimmung erfolgte bisher mittels Immunoassay. Mit der LC-MS/MS steht jedoch mittlerweile eine weitere wichtige analytische Methode in der quantitativen Bestimmung von Steroidhormonen zur Verf{\"u}gung, welche in dieser Arbeit im Hinblick auf den Kochsalzbelastungstest untersucht wurde. Hohe Bedeutung kommt außerdem der Subtypdifferenzierung des PA zu, da die {\"A}tiologie der Erkrankung wegweisend f{\"u}r die Art der Therapie ist. Das Ziel dieser Studie war einerseits die Ermittlung eines LC-MS/MS-spezifischen Aldosteron-Cut-off-Wertes im Kochsalzbelastungstest und die Evaluation des Nutzens der Bestimmung von Steroidprofilen in der Diagnostik des PA. Zum anderen wurde der diagnostische Nutzen des Orthostasetests zur Unterscheidung von unilateraler und bilateraler Genese bei vorliegendem PA untersucht. Im Rahmen dieser Studien wurden 187 bzw. 158 Patient:innen analysiert, die zwischen 2009 und 2019 bei Verdacht auf oder Vorliegen eines PA im Universit{\"a}tsklinikum W{\"u}rzburg vorstellig wurden. Die Diagnose wurde gem{\"a}ß der aktuellen Leitlinie anhand der Ergebnisse des Kochsalzbelastungstests, NNVKs, Bildgebung und postoperativen Outcomes gestellt. Mithilfe der LC-MS/MS wurden erneut die Aldosteronkonzentrationen der aufbewahrten Serumproben des Kochsalzbelastungstests, sowie ein erweitertes Steroidpanel bestimmt. Unter Verwendung einer ROC-Analyse wurden die jeweils bestehenden Cut-off-Werte optimiert bzw. neu ermittelt. Die mittels Immunoassay bestimmten Aldosteronkonzentrationen lagen um 28 ng/L h{\"o}her als die mittels LC-MS/MS bestimmten Konzentrationen. Trotzdem lag der neu ermittelte LC-MS/MS-spezifische Aldosteron-Cut-off-Wert f{\"u}r den Kochsalzbelastungstest bei 69 ng/L und damit h{\"o}her als der f{\"u}r den Immunoassay geltende, optimierte Aldosteron-Cut-off von 54 ng/L. Unter Verwendung des LC-MS/MS- spezifischen Cut-off-Werts erreichte der Kochsalzbelastungstest eine Sensitivit{\"a}t von 78,6\% bei einer Spezifit{\"a}t von 89,3\%. Die Sensitivit{\"a}t des Immunoassay-spezifischen Cut-off-Werts betrug 95,2\% bei einer Spezifit{\"a}t von 86,9\%. Das Bestimmen des gesamten Steroidprofils f{\"u}hrte zu keiner zus{\"a}tzlichen diagnostischen Information bei Durchf{\"u}hrung des Kochsalzbelastungstests. Bei Betrachtung der gesamten Patient:innenkohorte erreichte der Orthostasetest, basierend auf einem Absinken der Plasmaaldosteronkonzentration nach 4h in Orthostase um ≥ 28\% eine Sensitivit{\"a}t von 36,7\% bei einer Spezifit{\"a}t von 100\%. Wurde das Vorliegen eines g{\"u}ltigen Tests (Cortisolabfall nach 4h ≥ 10\%) oder das Vorliegen einer unilateralen Raumforderung in der Bildgebung vorausgesetzt, stieg die Sensitivit{\"a}t des Orthostasetests auf 51,4\% bzw. 51,6\% bei gleichbleibend hoher Spezifit{\"a}t von 100\% an. Abschließend l{\"a}sst sich sagen, dass der Orthostasetest keine Alternative zum NNVK darstellt, jedoch als einfache, nicht invasive Methode der zus{\"a}tzlichen Orientierung zur Untersuchung der {\"A}tiologie des PAs dienen kann. Eine prospektive Evaluation der jeweils neu ermittelten Cut-off-Werte wird notwendig sein, um deren Anwendbarkeit im klinischen Alltag zu {\"u}berpr{\"u}fen.

Here we show that IL-4-activated STAT6 transcription factor is required for the direct transcriptional repression of a large number of genes during in vitro and in vivo alternative macrophage polarization. Repression results in decreased lineage-determining transcription factor, p300, and RNA polymerase II binding followed by reduced enhancer RNA expression, H3K27 acetylation, and chromatin accessibility. The repressor function of STAT6 is HDAC3 dependent on a subset of IL-4-repressed genes. In addition, STAT6-repressed enhancers show extensive overlap with the NF-κB p65 cistrome and exhibit decreased responsiveness to lipopolysaccharide after IL-4 stimulus on a subset of genes. As a consequence, macrophages exhibit diminished inflammasome activation, decreased IL-1β production, and pyroptosis. Thus, the IL-4-STAT6 signaling pathway establishes an alternative polarization-specific epigenenomic signature resulting in dampened macrophage responsiveness to inflammatory stimuli.}, language = {en} }
