    (Nature Publishing Group, 2015-04-23) Yin, Xianyong; Low, Hui Qi; Wang, Ling; Li, Yonghong; Ellinghaus, Eva; Han, Jiali; Estivill, Xavier; Sun, Liangdan; Zuo, Xianbo; Shen, Changbing; Zhu, Caihong; Zhang, Anping; Sanchez, Fabio; Padyukov, Leonid; Catanese, Joseph J.; Krueger, Gerald G.; Duffin, Kristina Callis; Mucha, Sören; Weichenthal, Michael; Weidinger, Stephan; Lieb, Wolfgang; Foo, Jia Nee; Li, Yi; Sim, Karseng; Liany, Herty; Irwan, Ishak; Teo, Yikying; Theng, Colin T.

    Psoriasis is a common inflammatory skin disease with complex genetics and different degrees of prevalence across ethnic populations. Here we present the largest trans-ethnic genome-wide meta-analysis (GWMA) of psoriasis in 15,369 cases and 19,517 controls of Caucasian and Chinese ancestries. We identify four novel associations at LOC144817, COG6, RUNX1 and TP63, as well as three novel secondary associations within IFIH1 and IL12B. Fine-mapping analysis of MHC region demonstrates an important role for all three HLA class I genes and a complex and heterogeneous pattern of HLA associations between Caucasian and Chinese populations. Further, trans-ethnic comparison suggests population-specific effect or allelic heterogeneity for 11 loci. These population-specific effects contribute significantly to the ethnic diversity of psoriasis prevalence. This study not only provides novel biological insights into the involvement of immune and keratinocyte development mechanism, but also demonstrates a complex and heterogeneous genetic architecture of psoriasis susceptibility across ethnic populations.

    National Psoriasis Foundation COVID-19 Task Force Guidance for Management of Psoriatic Disease During the Pandemic: Version 1
    (Elsevier, 2020) Gelfand, Joel M.; Armstrong, April W.; Bell, Stacie; Anesi, George L.; Blauvelt, Andrew; Calabrese, Cassandra; Dommasch, Erica D.; Feldman, Steve R.; Gladman, Dafna; Kircik, Leon; Lebwohl, Mark; Lo Re, Vincent, III; Martin, George; Merola, Joseph F.; Scher, Jose U.; Schwartzman, Sergio; Treat, James R.; Van Voorhees, Abby S.; Ellebrecht, Christoph T.; Fenner, Justine; Ocon, Anthony; Syed, Maha N.; Weinstein, Erica J.; Smith, Jessica; Gondo, George; Heydon, Sue; Koons, Samantha; Ritchlin, Christopher T.; Medicine, School of Medicine
    Objective To provide guidance about management of psoriatic disease during the coronavirus disease 2019 (COVID-19) pandemic. Study design A task force (TF) of 18 physician voting members with expertise in dermatology, rheumatology, epidemiology, infectious diseases, and critical care was convened. The TF was supplemented by nonvoting members, which included fellows and National Psoriasis Foundation (NPF) staff. Clinical questions relevant to the psoriatic disease community were informed by questions received by the NPF. A Delphi process was conducted. Results The TF approved 22 guidance statements. The average of the votes was within the category of agreement for all statements. All guidance statements proposed were recommended, 9 with high consensus and 13 with moderate consensus. Limitations The evidence behind many guidance statements is limited in quality. Conclusion These statements provide guidance for the management of patients with psoriatic disease on topics ranging from how the disease and its treatments impact COVID-19 risk and outcome, how medical care can be optimized during the pandemic, what patients should do to lower their risk of getting infected with severe acute respiratory syndrome coronavirus 2 and what they should do if they develop COVID-19. The guidance is intended to be a living document that will be updated by the TF as data emerge.

    National Psoriasis Foundation COVID-19 Task Force guidance for management of psoriatic disease during the pandemic: Version 2—Advances in psoriatic disease management, COVID-19 vaccines, and COVID-19 treatments
    (Elsevier, 2021-05) Gelfand, Joel M.; Armstrong, April W.; Bell, Stacie; Anesi, George L.; Blauvelt, Andrew; Calabrese, Cassandra; Dommasch, Erica D.; Feldman, Steven R.; Gladman, Dafna; Kircik, Leon; Lebwohl, Mark; Lo Re, Vincent, III; Martin, George; Merola, Joseph F.; Scher, Jose U.; Schwartzman, Sergio; Treat, James R.; Van Voorhees, Abby S.; Ellebrecht, Christoph T.; Fenner, Justine; Ocon, Anthony; Syed, Maha N.; Weinstein, Erica J.; Gondo, George; Heydon, Sue; Koons, Samantha; Ritchlin, Christopher T.; Dermatology, School of Medicine
    Objective To update guidance regarding the management of psoriatic disease during the COVID-19 pandemic. Study Design The task force (TF) includes 18 physician voting members with expertise in dermatology, rheumatology, epidemiology, infectious diseases, and critical care. The TF was supplemented by nonvoting members, which included fellows and National Psoriasis Foundation staff. Clinical questions relevant to the psoriatic disease community were informed by inquiries received by the National Psoriasis Foundation. A Delphi process was conducted. Results The TF updated evidence for the original 22 statements and added 5 new recommendations. The average of the votes was within the category of agreement for all statements, 13 with high consensus and 14 with moderate consensus. Limitations The evidence behind many guidance statements is variable in quality and/or quantity. Conclusions These statements provide guidance for the treatment of patients with psoriatic disease on topics including how the disease and its treatments affect COVID-19 risk, how medical care can be optimized during the pandemic, what patients should do to lower their risk of getting infected with severe acute respiratory syndrome coronavirus 2 (including novel vaccination), and what they should do if they develop COVID-19. The guidance is a living document that is continuously updated by the TF as data emerge.
