Erythropoiesis defect observed in STAT3 GOF patients with severe anemia.

STAT3 mediates inflammation and modulates immunity. We found that in addition to its role in autoimmunity, over-activated STAT3 interferes in early erythro-myeloid precursor development and reduces commitment towards the erythroid lineage by interfering with the erythropoietin-STAT5 signalling pathway

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.
