In our study, 33 individuals with different autoimmune diseases were treated with cyclophosphamide according to standard protocols. The responses to the treatments were determined by measuring the alteration of several typical parameters characterizing the given autoimmune diseases over time. We concluded that about 45% of the patients responded to the treatment. Patients were genotyped for polymorphisms of the CYP3A4, CYP2B6, GSTM1, GSTT1, and GSTP1 genes and disease remission cases were compared to the individual polymorphic genotypes. It was found that the GSTP1 I105V allelic variation significantly associated with the cyclophosphamide treatment-dependent disease-remissions. At the same time the GSH content of the erythrocytes in the patients with I105V allelic variation did not change. It appears that the individuals carrying the Ile105Val SNP in at least one copy had a significantly higher response rate to the treatment. Since this variant of GSTP1 can be characterized by lower conjugation capacity that results in an elongated and higher therapeutic dose of cyclophosphamide, our data suggest that the decreased activity of this variant of GSTP1 can be in the background of the more effective disease treatment.<\/jats:p>","DOI":"10.3390\/molecules25071542","type":"journal-article","created":{"date-parts":[[2020,4,3]],"date-time":"2020-04-03T05:55:16Z","timestamp":1585893316000},"page":"1542","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Genetic Polymorphism of GSTP-1 Affects Cyclophosphamide Treatment of Autoimmune Diseases"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7705-2074","authenticated-orcid":false,"given":"P\u00e9ter","family":"Hajdin\u00e1k","sequence":"first","affiliation":[{"name":"Department of Applied Biotechnology and Food Science, Laboratory of Biochemistry and Molecular Biology, Budapest University of Technology and Economics, Szent Gell\u00e9rt t\u00e9r 4., Budapest 1111, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melinda","family":"Szab\u00f3","sequence":"additional","affiliation":[{"name":"National Institute of Rheumatology and Physiotherapy, Clinical Immunology Adult and Pediatric Rheumatology, Frankel Le\u00f3 u. 25-29., Budapest 1023, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emese","family":"Kiss","sequence":"additional","affiliation":[{"name":"National Institute of Rheumatology and Physiotherapy, Clinical Immunology Adult and Pediatric Rheumatology, Frankel Le\u00f3 u. 25-29., Budapest 1023, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lili","family":"Veress","sequence":"additional","affiliation":[{"name":"National Institute of Rheumatology and Physiotherapy, Clinical Immunology Adult and Pediatric Rheumatology, Frankel Le\u00f3 u. 25-29., Budapest 1023, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L\u00edvius","family":"Wunderlich","sequence":"additional","affiliation":[{"name":"Department of Applied Biotechnology and Food Science, Laboratory of Biochemistry and Molecular Biology, Budapest University of Technology and Economics, Szent Gell\u00e9rt t\u00e9r 4., Budapest 1111, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6594-254X","authenticated-orcid":false,"given":"Andr\u00e1s","family":"Szarka","sequence":"additional","affiliation":[{"name":"Department of Applied Biotechnology and Food Science, Laboratory of Biochemistry and Molecular Biology, Budapest University of Technology and Economics, Szent Gell\u00e9rt t\u00e9r 4., Budapest 1111, Hungary"},{"name":"Pathobiochemistry Research Group of Hungarian Academy of Sciences and Semmelweis University, P.O.
