A dysbalance between FoxP3+ regulatory CD4+ T cells (Tregs) and inflammatory T-helper (Th) 17 cells has been suggested. Methods: The study aimed (1) to investigate the phenotypical and functional characteristics of Th17 and Tregs in SSc patients depending on disease manifestation (limited vs. diffuse cutaneous SSc, dcSSc) and activity, and (2) the transcriptional level and methylation status of Th17- and Treg-specific transcription factors. Results: There was a concurrent accumulation of circulating peripheral IL-17-producing CCR6+ Th cells and FoxP3+ Tregs in patients with dcSSc. At the transcriptional level, Th17- and Treg-associated transcription factors were elevated in SSc. A strong association with high circulating Th17 and Tregs was seen with early, active, and severe disease presentation. However, a diminished suppressive function on autologous lymphocytes was found in SSc-derived Tregs. Significant relative hypermethylation was seen at the gene level for RORC1 and RORC2 in SSc, particularly in patients with high inflammatory activity. Conclusions: Besides the high transcriptional activity of T cells, attributed to Treg or Th17 phenotype, in active SSc disease, Tregs may be insufficient to produce high amounts of IL-10 or to control proliferative activity of effector T cells in SSc. Our results suggest a high plasticity of Tregs strongly associated with the Th17 phenotype. Future directions may focus on enhancing Treg functions and stabilization of the Treg phenotype.}, language = {en} } @article{KepplerWeissbachLangeretal.2016, author = {Keppler, Sarah and Weißbach, Susann and Langer, Christian and Knop, Stefan and Pischimarov, Jordan and Kull, Miriam and St{\"u}hmer, Thorsten and Steinbrunn, Torsten and Bargou, Ralf and Einsele, Hermann and Rosenwald, Andreas and Leich, Ellen}, title = {Rare SNPs in receptor tyrosine kinases are negative outcome predictors in multiple myeloma}, series = {Oncotarget}, volume = {7}, journal = {Oncotarget}, number = {25}, doi = {10.18632/oncotarget.9607}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-177840}, pages = {38762-38774}, year = {2016}, abstract = {Multiple myeloma (MM) is a plasma cell disorder that is characterized by a great genetic heterogeneity. Recent next generation sequencing studies revealed an accumulation of tumor-associated mutations in receptor tyrosine kinases (RTKs) which may also contribute to the activation of survival pathways in MM. To investigate the clinical role of RTK-mutations in MM, we deep-sequenced the coding DNA-sequence of EGFR, EPHA2, ERBB3, IGF1R, NTRK1 and NTRK2 which were previously found to be mutated in MM, in 75 uniformly treated MM patients of the "Deutsche Studiengruppe Multiples Myelom". Subsequently, we correlated the detected mutations with common cytogenetic alterations and clinical parameters. We identified 11 novel non-synonymous SNVs or rare patient-specific SNPs, not listed in the SNP databases 1000 genomes and dbSNP, in 10 primary MM cases. The mutations predominantly affected the tyrosine-kinase and ligand-binding domains and no correlation with cytogenetic parameters was found. Interestingly, however, patients with RTK-mutations, specifically those with rare patient-specific SNPs, showed a significantly lower overall, event-free and progression-free survival. This indicates that RTK SNVs and rare patient-specific RTK SNPs are of prognostic relevance and suggests that MM patients with RTK-mutations could potentially profit from treatment with RTK-inhibitors.}, language = {en} } @article{WernerBeykanHiguchietal.2016, author = {Werner, Rudolf A. and Beykan, Seval and Higuchi, Takahiro and L{\"u}ckerath, Katharina and Weich, Alexander and Scheurlen, Michael and Bluemel, Christina and Herrmann, Ken and Buck, Andreas K. and Lassmann, Michael and Lapa, Constantin and H{\"a}nscheid, Heribert}, title = {The impact of \(^{177}\)Lu-octreotide therapy on \(^{99m}\)Tc-MAG3 clearance is not predictive for late nephropathy}, series = {Oncotarget}, volume = {7}, journal = {Oncotarget}, number = {27}, doi = {10.18632/oncotarget.9775}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-177318}, pages = {41233-41241}, year = {2016}, abstract = {Peptide Receptor Radionuclide Therapy (PRRT) for the treatment of neuroendocrine tumors may lead to kidney deterioration.

The progress of liver fibrosis and cirrhosis is accompanied by deteriorating liver function. This review summarizes the regulatory and functional changes in phase I and phase II metabolic enzymes as well as transport proteins and provides an overview regarding lipid and glucose metabolism in cirrhotic patients. Interestingly, phase I enzymes are generally downregulated transcriptionally, while phase II enzymes are mostly preserved transcriptionally but are reduced in their function. Transport proteins are regulated in a specific way that resembles the molecular changes observed in obstructive cholestasis. Lipid and glucose metabolism are characterized by insulin resistance and catabolism, leading to the disturbance of energy expenditure and wasting. Possible non-invasive tests, especially breath tests, for components of liver metabolism are discussed. The heterogeneity and complexity of changes in hepatic metabolism complicate the assessment of liver function in individual patients. Additionally, studies in humans are rare, and species differences preclude the transferability of data from rodents to humans.

Patients and methods Untreated patients with MPC (N = 861) received nab-P + Gem or Gem alone. CA19-9 was evaluated at baseline and every 8 weeks. Results Patients with baseline and week-8 CA19-9 measurements were analyzed (nab-P + Gem: 252; Gem: 202).

It is important to test these recommended protocols on nonsimulated "in vivo" specimens before full clinical evaluation. The testing of an animal model of invasive aspergillosis (IA) overcomes the low incidence of disease and provides experimental design and control that is not possible in the clinical setting. Inadequate performance of the recommended protocols at this stage would require reassessment of methods before clinical trials are performed and utility assessed. The manuscript describes the performance of EAPCRI protocols in an animal model of invasive aspergillosis. Blood samples taken from a guinea pig model of IA were used for WB and serum PCR. Galactomannan and beta-D-glucan detection were evaluated, with particular focus on the timing of positivity and on the interpretation of combination testing. The overall sensitivities for WB PCR, serum PCR, galactomannan, and beta-D-glucan were 73\%, 65\%, 68\%, and 46\%, respectively. The corresponding specificities were 92\%, 79\%, 80\%, and 100\%, respectively. PCR provided the earliest indicator of IA, and increasing galactomannan and beta-D-glucan values were indicators of disease progression. The combination of WB PCR with galactomannan and beta-D-glucan proved optimal (area under the curve AUC], 0.95), and IA was confidently diagnosed or excluded. The EAPRCI-recommended PCR protocols provide performance comparable to commercial antigen tests, and clinical trials are warranted. By combining multiple tests, IA can be excluded or confirmed, highlighting the need for a combined diagnostic strategy.

Fungi and Toxoplasma gondii are the predominant causative agents. The diagnosis of CNS infections is based on neuroimaging, cerebrospinal fluid examination and biopsy of suspicious lesions in selected patients.

Conclusions MBDA improved the prediction of relapses in patients with RA in stable remission undergoing DMARD tapering. If combined with ACPA testing, MBDA allowed prediction of relapse in more than 80\% of the patients.

Methods We used an analysis of variance model in patients on stable therapy (discovery cohort) to establish critical differences (d(crit)) for the minimum change associated with a significant individual patient response (beyond normal variation) in the PRO measures of pain (0-10), fatigue (0-10), and function (Funktionsfragebogen Hannover questionnaire; 0-100). We then evaluated PRO responses in patients initiating adalimumab in a noninterventional study (treatment cohort). Results In the discovery cohort (n=700), PROs showed excellent long-term retest reliability. The minimum change that exceeded random fluctuation was conservatively determined to be 3 points for pain, 4 points for fatigue, and 16 points for function. In the treatment cohort (n=2,788), 1,483 patients (53.2\%) achieved a significant individual therapeutic response as assessed by Disease Activity Score in 28 joints (DAS28)-d(crit) (1.8 points) after 12 months of adalimumab treatment; 68.5\% of patients with a DAS28-d(crit) response achieved a significant improvement in pain, whereas approximately 40\% achieved significant improvements in fatigue or function. Significant improvements in all 3 PROs occurred in 22.7\% of patients; 22.8\% did not have any significant PRO responses. In contrast, significant improvements in all 3 PROs occurred in only 4.4\% of 1,305 patients who did not achieve a DAS28-d(crit) response at month 12, and 59.1\% did not achieve any significant PRO responses.

A growing number of studies suggest a major host genetic component in disease susceptibility. Here, we evaluated whether 14 single-nucleotide polymorphisms within NFκB1, NFκB2, RelA, RelB, Rel, and IRF4 genes influence the risk of IA in a population of 834 high-risk patients (157 IA and 677 non-IA) recruited through a collaborative effort involving the aspBIOmics consortium and four European clinical institutions. No significant overall associations between selected SNPs and the risk of IA were found in this large cohort. Although a hematopoietic stem cell transplantation (HSCT)-stratified analysis revealed that carriers of the IRF4rs12203592T/T genotype had a six-fold increased risk of developing the infection when compared with those carrying the C allele (ORREC = 6.24, 95\%CI 1.25-31.2, P = 0.026), the association of this variant with IA risk did not reach significance at experiment-wide significant threshold. In addition, we found an association of the IRF4AATC and IRF4GGTC haplotypes (not including the IRF4rs12203592T risk allele) with a decreased risk of IA but the magnitude of the association was similar to the one observed in the single-SNP analysis, which indicated that the haplotypic effect on IA risk was likely due to the IRF4rs12203592 SNP. Finally, no evidence of significant interactions among the genetic markers tested and the risk of IA was found. These results suggest that the SNPs on the studied genes do not have a clinically relevant impact on the risk of developing IA.}, language = {en} } @article{SchofferSchueleinArandetal.2016, author = {Schoffer, Olaf and Sch{\"u}lein, Stefanie and Arand, Gerlinde and Arnholdt, Hans and Baaske, Dieter and Bargou, Ralf C. and Becker, Nikolaus and Beckmann, Matthias W. and Bodack, Yves and B{\"o}hme, Beatrix and Bozkurt, Tayfun and Breitsprecher, Regine and Buchali, Andre and Burger, Elke and Burger, Ulrike and Dommisch, Klaus and Elsner, Gudrun and Fernschild, Karin and Flintzer, Ulrike and Funke, Uwe and Gerken, Michael and G{\"o}bel, Hubert and Grobe, Norbert and Gumpp, Vera and Heinzerling, Lucie and Kempfer, Lana Raffaela and Kiani, Alexander and Klinkhammer-Schalke, Monika and Kl{\"o}cking, Sabine and Kreibich, Ute and Knabner, Katrin and Kuhn, Peter and Lutze, Stine and M{\"a}der, Uwe and Maisel, Tanja and Maschke, Jan and Middeke, Martin and Neubauer, Andreas and Niedostatek, Antje and Opazo-Saez, Anabelle and Peters, Christoph and Schell, Beatrice and Schenkirsch, Gerhard and Schmalenberg, Harald and Schmidt, Peter and Schneider, Constanze and Schubotz, Birgit and Seide, Anika and Strecker, Paul and Taubenheim, Sabine and Wackes, Matthias and Weiß, Steffen and Welke, Claudia and Werner, Carmen and Wittekind, Christian and Wulff, J{\"o}rg and Zettl, Heike and Klug, Stefanie J.}, title = {Tumour stage distribution and survival of malignant melanoma in Germany 2002-2011}, series = {BMC Cancer}, volume = {16}, journal = {BMC Cancer}, number = {936}, doi = {10.1186/s12885-016-2963-0}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-164544}, year = {2016}, abstract = {Background Over the past two decades, there has been a rising trend in malignant melanoma incidence worldwide. In 2008, Germany introduced a nationwide skin cancer screening program starting at age 35. The aims of this study were to analyse the distribution of malignant melanoma tumour stages over time, as well as demographic and regional differences in stage distribution and survival of melanoma patients. Methods Pooled data from 61 895 malignant melanoma patients diagnosed between 2002 and 2011 and documented in 28 German population-based and hospital-based clinical cancer registries were analysed using descriptive methods, joinpoint regression, logistic regression and relative survival. Results The number of annually documented cases increased by 53.2\% between 2002 (N = 4 779) and 2011 (N = 7 320). There was a statistically significant continuous positive trend in the proportion of stage UICC I cases diagnosed between 2002 and 2011, compared to a negative trend for stage UICC II. No trends were found for stages UICC III and IV respectively. Age (OR 0.97, 95\% CI 0.97-0.97), sex (OR 1.18, 95\% CI 1.11-1.25), date of diagnosis (OR 1.05, 95\% CI 1.04-1.06), 'diagnosis during screening' (OR 3.24, 95\% CI 2.50-4.19) and place of residence (OR 1.23, 95\% CI 1.16-1.30) had a statistically significant influence on the tumour stage at diagnosis. The overall 5-year relative survival for invasive cases was 83.4\% (95\% CI 82.8-83.9\%). Conclusions No distinct changes in the distribution of malignant melanoma tumour stages among those aged 35 and older were seen that could be directly attributed to the introduction of skin cancer screening in 2008.

The historical cohort included 694 patients with CR data and 1112 patients with OS data compared with 189 patients with CR and survival data in the blinatumomab trial. The weighted analysis revealed a CR rate of 24\% (95\% CI: 20-27\%) and a median OS of 3.3 months (95\% CI: 2.8-3.6) in the historical cohort compared with a CR/CRh rate of 43\% (95\% CI: 36-50\%) and a median OS of 6.1 months (95\% CI: 4.2-7.5) in the blinatumomab trial.
