31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two

Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival

Dependence of the textural properties and surface species of ZnO photocatalytic materials on the type of precipitating agent used in the hydrothermal synthesis

Three different precipitating agents (NaOH, NH4(H)CO3 and CO(NH2)2) have been applied for the hydrothermal synthesis of ZnO powder materials, aiming at obtaining various types of porosity and surface species on ZnO. The synthesis procedures were carried out in the presence and in the absence of tri-block copolymer Pluronic (P123, EO20PO70EO20). These materials were characterized by powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM)–energy-dispersive X-ray spectroscopy (EDX), BET method and TG–differential thermal analysis (DTA) method, and their photocatalytic activities were tested in the removal of azo dye Reactive Black 5 (RB5). The urea precipitant yields spongy-like surface forms and the greatest share of mesopores. It has the highest specific surface area, the highest degree of crystallinity of wurtzite ZnO phase and largest content of surface OH groups in comparison with the other two precipitants. The zinc hydroxycarbonate intermediate phase is missing in the case of NaOH as a precipitating agent; therefore, it manifests poorer textural characteristics. The morphology of P123-modified sample is different and consists of needle-shaped particles. The urea-precipitated samples display superior performance in the photocatalytic oxidation reaction, compared with the other precipitated samples. The other two precipitating agents are inferior in regard to their photocatalytic activity due to a greater share of micropores (not well-illuminated inner surface) and different surface morphologies

DISCOLORATION OF REACTIVE DYES IN WASTEWATERS BY OZONATION

Three different reactive dyes - Reactive Blue 19, Reactive Orange 16 and Reactive Red 180 were dissolved in water separately in concentration 0.04g/l as model pollutants for contaminated wastewaters from textile industry. Every wastewater sample was treated by ozone with concentration 2000 ppm for 30 minutes at ambient temperature and the effect of discoloration was traced after 5, 10, 20 and 30 minutes. The highest degree of discoloration was obtained for Reactive Blue 19 model water pollutant dye where 98% discoloration was reached after 5 minutes ozonation and 99% after 30 minutes treatment, while the lowest discoloration was observed for Reactive Orange 16 – 84% after 30 minutes treatment. The discoloration degree for the three sample solutions in the whole time interval was as follows: Reactive Blue 19 > Reactive Red 180 > Reactive Orange 16. In summary it can be concluded than application of ozone treatment for wastewaters, containing different reactive dyes is very effective and practically applicable

Acute Kidney Injury and Acute Renal Failure in Coronaviral Infection

In December 2019 a newly described single-stranded coronavirus, later named SARS-CoV-2, started its expansion around the world and subsequently caused a global pandemic, affecting the lives of millions of people worldwide. SARS-CoV-2 can bind multiple receptors on different cells and thus invade many target organs, including the respiratory and gastrointestinal mucous membranes, lungs, central nervous system, heart, etc. This virus can affect the kidney tissue both directly and as a consequence of other organ involvement or of the treatment administered, causing acute kidney injury and leaving long term squeals that worsen the prognosis. We describe three patients with acute kidney injury and subsequent acute renal failure at the background of coronaviral infection

Initial presenting manifestations in 16,486 patients with inborn errors of immunity include infections and noninfectious manifestations

none313siBackground: Inborn errors of immunity (IEI) are rare diseases, which makes diagnosis a challenge. A better description of the initial presenting manifestations should improve awareness and avoid diagnostic delay. Although increased infection susceptibility is a well-known initial IEI manifestation, less is known about the frequency of other presenting manifestations. Objective: We sought to analyze age-related initial presenting manifestations of IEI including different IEI disease cohorts. Methods: We analyzed data on 16,486 patients of the European Society for Immunodeficiencies Registry. Patients with autoinflammatory diseases were excluded because of the limited number registered. Results: Overall, 68% of patients initially presented with infections only, 9% with immune dysregulation only, and 9% with a combination of both. Syndromic features were the presenting feature in 12%, 4% had laboratory abnormalities only, 1.5% were diagnosed because of family history only, and 0.8% presented with malignancy. Two-third of patients with IEI presented before the age of 6 years, but a quarter of patients developed initial symptoms only as adults. Immune dysregulation was most frequently recognized as an initial IEI manifestation between age 6 and 25 years, with male predominance until age 10 years, shifting to female predominance after age 40 years. Infections were most prevalent as a first manifestation in patients presenting after age 30 years. Conclusions: An exclusive focus on infection-centered warning signs would have missed around 25% of patients with IEI who initially present with other manifestations.noneThalhammer J.; Kindle G.; Nieters A.; Rusch S.; Seppanen M.R.J.; Fischer A.; Grimbacher B.; Edgar D.; Buckland M.; Mahlaoui N.; Ehl S.; Boztug K.; Brunner J.; Demel U.F.; Forster-Waldl E.; Gasteiger L.M.; Goschl L.; Kojic M.; Schroll A.; Seidel M.G.; Wintergerst U.; Wisgrill L.; Sharapova S.O.; Goffard J.-C.; Kerre T.; Meyts I.; Roosens F.; Smet J.; Haerynck F.; Eric Z.P.; Milenova V.; Gagro A.; Richter D.; Chovancova Z.; Hlavackova E.; Litzman J.; Milota T.; Sediva A.; Elaziz D.A.; Alkady R.S.; El Sayed El Hawary R.; Eldash A.S.; Galal N.; Lotfy S.; Meshaal S.S.; Reda S.M.; Sobh A.; Elmarsafy A.; Brosselin P.; Courteille V.; De Vergnes N.; Kracker S.; Pergent M.; Randrianomenjanahary P.; Ahrenstorf G.; Albert M.H.; Ankermann T.; Atschekzei F.; Baumann U.; Becker B.C.; Behrends U.; Belohradsky B.H.; Biegner A.-K.; Binder N.; Bode S.F.N.; Boesecke C.; Boetticher B.; Borte M.; Borte S.; Classen C.F.; Dirks J.; Duckers G.; El-Helou S.; Ernst D.; Fasshauer M.; Fecker G.; Felgentreff K.; Foell D.; Ghosh S.; Girschick H.J.; Goldacker S.; Graf N.; Graf D.; Greil J.; Hanitsch L.G.; Hauck F.; Heeg M.; Heine S.I.; Henes J.C.; Hoenig M.; Holzer U.; Holzinger D.; Horneff G.; Hundsdoerfer P.; Jablonka A.; Jakoby D.; Joean O.; Kaiser-Labusch P.; Klemann C.; Kobbe R.; Korholz J.; Kramm C.M.; Kruger R.; Landwehr-Kenzel S.; Lehmberg K.; Liese J.G.; Lippert C.F.; Maccari M.E.; Masjosthusmann K.; Meinhardt A.; Metzler M.; Morbach H.; Muller I.; Naumann-Bartsch N.; Neubert J.; Niehues T.; Peter H.-H.; Rieber N.; Ritterbusch H.; Rockstroh J.K.; Roesler J.; Schauer U.; Scheible R.; Schmalzing M.; Schmidt R.E.; Schneider D.T.; Schreiber S.; Schuetz C.; Schulz A.; Schulze-Koops H.; Schulze-Sturm U.; Schuster V.; Schwaneck E.C.; Schwarz K.; Schwarze-Zander C.; Sirin M.; Skapenko A.; Sogkas G.; Sparber-Sauer M.; Speckmann C.; Steinmann S.; Stiehler S.; Tenbrock K.; von Bernuth H.; Warnatz K.; Wasmuth J.-C.; Weiss M.; Witte T.; Wittke K.; Wittkowski H.; Zeuner R.A.; Farmaki E.; Hatzistilianou M.N.; Kakkas I.; Kanariou M.G.; Kapousouzi A.; Liatsis E.; Maggina P.; Papadopoulou-Alataki E.; Raptaki M.; Speletas M.; Tantou S.; Goda V.; Krivan G.; Marodi L.; Abolhassani H.; Aghamohammadi A.; Rezaei N.; Feighery C.; Leahy T.R.; Ryan P.; Batzir N.A.; Garty B.Z.; Tamary H.; Aiuti A.; Amodio D.; Azzari C.; Barzaghi F.; Baselli L.A.; Cancrini C.; Carrabba M.; Cazzaniga M.; Cesaro S.; Chinello M.; Danieli M.G.; Dellepiane R.M.; Fabio G.; Gambineri E.; Lodi L.; Lougaris V.; Marasco C.; Martire B.; Marzollo A.; Milito C.; Moschese V.; Pignata C.; Plebani A.; Porta F.; Quinti I.; Ricci S.; Soresina A.; Tommasini A.; Vacca A.; Vanessa C.; Blaziene A.; Sitkauskiene B.; Gowin E.; Heropolitanska-Pliszka E.; Pietrucha B.; Szaflarska A.; Wiesik-Szewczyk E.; Wolska-Kusnierz B.; Esteves I.; Faria E.; Marques L.H.; Neves J.F.; Silva S.L.; Teixeira C.; Pereira da Silva S.; Capilna B.R.; Guseva M.N.; Shcherbina A.; Bobcakova A.; Ciznar P.; Gabzdilova J.; Jesenak M.; Kapustova L.; Orosova J.; Petrovicova O.; Raffac S.; Kopac P.; Allende L.M.; Antoli A.; Blanch G.R.; Carbone J.; Dieli-Crimi R.; Garcia-Prat M.; Gil-Herrera J.; Gonzalez-Granado L.I.; Agullo P.L.; Olbrich P.; Parra-Martinez A.; Paz-Artal E.; Pleguezuelo D.E.; Rodriguez N.S.; Sanchez-Ramon S.; Santos-Perez J.L.; Solanich X.; Soler-Palacin P.; Gonzalez-Amores M.; Ekwall O.; Fasth A.; Bitzenhofer-Gruber M.; Candotti F.; Dimitriou F.; Heininger U.; Holbro A.; Jandus P.; Kolios A.G.A.; Marschall K.; Schmid J.P.; Posfay-Barbe K.M.; Prader S.; Reichenbach J.; Steiner U.C.; Truck J.; Bredius R.G.; de Kruijf- Bazen S.; de Vries E.; Henriet S.S.V.; Kuijpers T.W.; Potjewijd J.; Rutgers A.; Stol K.; van Aerde K.J.; Van den Berg J.M.; van de Ven A.A.J.M.; Montfrans J.; Aydemir S.; Baris S.; Dogu F.; Ikinciogullari A.; Karakoc-Aydiner E.; Kilic S.S.; Kiykim A.; Kokcu Karadag S.I.; Kutukculer N.; Ocak S.; UNAL E.; Boyarchuk O.; Hilfanova A.; Kostyuchenko L.V.; Alachkar H.; Arkwright P.D.; Baxendale H.E.; Bernatoniene J.; Coulter T.I.; Garcez T.; Goddard S.; Gompels M.M.; Grigoriadou S.; Herriot R.; Herwadkar A.; Huissoon A.; Ibberson L.; Nademi Z.; Noorani S.; Parvin S.; Steele C.L.; Thomas M.; Waruiru C.; Yong P.F.K.; Bourne H.Thalhammer, J.; Kindle, G.; Nieters, A.; Rusch, S.; Seppanen, M.
