According to the current literature, the parasite induces vigorous immune responses that are controlled by Th2 helper cells at the expense of Th1 helper cells. The latter cell type is, however, indispensable for anti-viral immune responses. Remarkably, there is no reliable literature among 230 million patients worldwide describing defective anti-viral immune responses in the upper respiratory tract, for instance against influenza A virus or against respiratory syncitial virus (RSV). We therefore re-examined the immune response to a human isolate of S. mansoni and challenged mice in the chronic phase of schistosomiasis with influenza A virus, or with pneumonia virus of mice (PVM), a mouse virus to model RSV infections. We found that mice with chronic schistosomiasis had significant, systemic immune responses induced by Th1, Th2, and Th17 helper cells. High serum levels of TNF-alpha, IFN-gamma, IL-5, IL-13, IL-2, IL-17, and GM-CSF were found after mating and oviposition. The lungs of diseased mice showed low-grade inflammation, with goblet cell hyperplasia and excessive mucus secretion, which was alleviated by treatment with an anti-TNF-alpha agent (Etanercept). Mice with chronic schistosomiasis were to a relative, but significant extent protected from a secondary viral respiratory challenge. The protection correlated with the onset of oviposition and TNF-alpha-mediated goblet cell hyperplasia and mucus secretion, suggesting that these mechanisms are involved in enhanced immune protection to respiratory viruses during chronic murine schistosomiasis. Indeed, also in a model of allergic airway inflammation mice were protected from a viral respiratory challenge with PVM.}, language = {en} } @article{ScheerVokuhlBlanketal.2019, author = {Scheer, Monika and Vokuhl, Christian and Blank, Bernd and Hallmen, Erika and von Kalle, Thekla and M{\"u}nter, Marc and Wessalowski, R{\"u}diger and Hartwig, Maite and Sparber-Sauer, Monika and Schlegel, Paul-Gerhardt and Kramm, Christof M. and Kontny, Udo and Spriewald, Bernd and Kegel, Thomas and Bauer, Sebastian and Kazanowska, Bernarda and Niggli, Felix and Ladenstein, Ruth and Ljungman, Gustaf and Jahnukainen, Kirsi and Fuchs, J{\"o}rg and Bielack, Stefan S. and Klingebiel, Thomas and Koscielniak, Ewa}, title = {Desmoplastic small round cell tumors: Multimodality treatment and new risk factors}, series = {Cancer Medicine}, volume = {8}, journal = {Cancer Medicine}, number = {2}, doi = {10.1002/cam4.1940}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-228444}, pages = {527-545}, year = {2019}, abstract = {Background To evaluate optimal therapy and potential risk factors. Methods Data of DSRCT patients <40 years treated in prospective CWS trials 1997-2015 were analyzed. Results Median age of 60 patients was 14.5 years. Male:female ratio was 4:1. Tumors were abdominal/retroperitoneal in 56/60 (93\%). 6/60 (10\%) presented with a localized mass, 16/60 (27\%) regionally disseminated nodes, and 38/60 (63\%) with extraperitoneal metastases. At diagnosis, 23/60 (38\%) patients had effusions, 4/60 (7\%) a thrombosis, and 37/54 (69\%) elevated CRP. 40/60 (67\%) patients underwent tumor resection, 21/60 (35\%) macroscopically complete. 37/60 (62\%) received chemotherapy according to CEVAIE (ifosfamide, vincristine, actinomycin D, carboplatin, epirubicin, etoposide), 15/60 (25\%) VAIA (ifosfamide, vincristine, adriamycin, actinomycin D) and, 5/60 (8\%) P6 (cyclophosphamide, doxorubicin, vincristine, ifosfamide, etoposide). Nine received high-dose chemotherapy, 6 received regional hyperthermia, and 20 received radiotherapy. Among 25 patients achieving complete remission, 18 (72\%) received metronomic therapies. Three-year event-free (EFS) and overall survival (OS) were 11\% (±8 confidence interval [CI] 95\%) and 30\% (±12 CI 95\%), respectively, for all patients and 26.7\% (±18.0 CI 95\%) and 56.9\% (±20.4 CI 95\%) for 25 patients achieving remission. Extra-abdominal site, localized disease, no effusion or ascites only, absence of thrombosis, normal CRP, complete tumor resection, and chemotherapy with VAIA correlated with EFS in univariate analysis. In multivariate analysis, significant factors were no thrombosis and chemotherapy with VAIA. In patients achieving complete remission, metronomic therapy with cyclophosphamide/vinblastine correlated with prolonged time to relapse. Conclusion Pleural effusions, venous thrombosis, and CRP elevation were identified as potential risk factors. The VAIA scheme showed best outcome. Maintenance therapy should be investigated further.}, language = {en} }
