Item Glutathione S-transferase M1 and T1 gene polymorphisms in patients with chronic plaque-type psoriasis: A case-control study(Karger, 2015-11-03) Solak, Berna; Karkucak, Mutlu; Turan, Hakan; Uslu, Esma; Erdem, Teoman; Ocakoğlu, Gökhan; Sağ, Şebnem Özemri; Yakut, Tahsin; Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Genetik Anabilim Dalı.; AAH-8355-2021; AAH-5180-2021; 57073882900; 57116515700; 6602802424Objective: To determine the role of glutathione S-transferase (GST) isoenzyme polymorphisms as susceptibility factors in patients with psoriasis in a Turkish cohort. Subjects and Methods: In this case-control study, 105 patients with plaque-type psoriasis and 102 healthy controls were recruited from the dermatology outpatient clinics of two university hospitals. Genomic DNA was extracted from whole blood using a DZ DNA isolation kit. Multiplex PCR was used to determine GSTM1 and GSTT1 polymorphisms in the isolated DNAs. Results: Of the 150 patients with psoriasis, 83 (79%) were identified with the GSTT1 genotype and 22 (21%) with the null genotype. Of the 102 patients in the control group, 69 (67.6%) subjects were identified with the GSTT1 genotype and 33 (32.4%) with the null genotype. There was no significant difference between the patient and control groups (p = 0.063). Regarding the GSTM1 polymorphism, 54 (51.4%) patients were identified with this genotype and 51 (48.6%) with the null genotype; in the control group, 50 (49%) were identified with this genotype and 52 (51%) with the null genotype. Again there was no statistically significant difference between the groups (p = 0.957). Conclusion: In this Turkish cohort of patients with psoriasis, neither GSTT1 nor GSTM1 polymorphisms were associated with disease susceptibility. Larger studies with a wider range of GST isoenzyme are needed.Item Recommendations on the use of systemic treatments for urticaria and atopic dermatitis during the COVID-19 pandemic: Statement of Dermatoallergy Working Group of the Turkish Society of Dermatology(Galenos Yayıncılık, 2020-12) Salman, Andaç; Alper, Sibel; Atakan, Nilgün; Borlu, Murat; Canpolat, Filiz; Erdem, Teoman; Erdem, Yasemin; Gül, Ülker; Kartal, Selda Pelin; Koca, Rafet; Küçük, Özlem Su; Başkan, Emel Bülbül; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Dermatoloji Anabilim Dalı.; 0000-0002-0144-3263; AAH-1388-2021; 6602518817
