Factors predicting HU, and its association with graft function, remains equivocal. Materials and Methods: We conducted a retrospective longitudinal study to assess factors associated with HU in KTR, and to determine risk factors associated with graft function, measured as glomerular filtration rate (GFR). Moreover, GFR &gt; 60 mL\/min\/1.73 m2 was considered normal. HU was defined as a serum uric acid level of &gt; 416 \u03bcmol\/L (4.70 mg\/dL) in men and &gt;357 \u03bcmol\/L (4.04 mg\/dL) in women, or xanthine-oxidase inhibitor use. We built multiple logistic regression models to assess predictors of HU in KTR, as well as the association of demographic, clinical, and biochemical parameters of patients with normal GFR after a three-year follow-up. We investigated the effect modification of this association with HU. Results: There were 144 patients (mean age 46.6 \u00b1 13.9), with 42.4% of them having HU. Predictors of HU in KTR were the presence of cystic diseases (OR = 9.68 (3.13; 29.9)), the use of diuretics (OR = 4.23 (1.51; 11.9)), and the male gender (OR = 2.45 (1.07; 5.56)). Being a younger age, of female gender, with a normal BMI, and the absence of diuretic medications increased the possibility of normal GFR. HU was the effect modifier of the association between demographic, clinical, and biochemical factors and a normal GFR. Conclusions: Factors associated with HU in KTR: Presence of cystic diseases, diuretic use, and male gender. HU was the effect modifier of the association of demographic, clinical, and biochemical factors to GFR.<\/jats:p>","DOI":"10.3390\/medicina56030095","type":"journal-article","created":{"date-parts":[[2020,2,25]],"date-time":"2020-02-25T08:12:22Z","timestamp":1582618342000},"page":"95","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Predictors of Hyperuricemia after Kidney Transplantation: Association with Graft Function"],"prefix":"10.3390","volume":"56","author":[{"given":"Inese","family":"Folkmane","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Univeristy of Latvia, LV-1004 Riga, Latvia"},{"name":"Pauls Stradins Clinical University Hospital, Centre of Nephrology of Latvia, LV-1002 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lilian","family":"Tzivian","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Univeristy of Latvia, LV-1004 Riga, Latvia"},{"name":"Holon Institute of Technology, Holon 5810201, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabete","family":"Folkmane","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Univeristy of Latvia, LV-1004 Riga, Latvia"},{"name":"St. Bonifatius Hospital, 49808 Lingen (Ems), Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elina","family":"Valdmane","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Univeristy of Latvia, LV-1004 Riga, Latvia"},{"name":"Pauls Stradins Clinical University Hospital, Centre of Nephrology of Latvia, LV-1002 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Viktorija","family":"Kuzema","sequence":"additional","affiliation":[{"name":"Pauls Stradins Clinical University Hospital, Centre of Nephrology of Latvia, LV-1002 Riga, Latvia"},{"name":"Faculty of medicine, Riga Stradins University, LV-1007 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aivars","family":"Petersons","sequence":"additional","affiliation":[{"name":"Pauls Stradins Clinical University Hospital, Centre of Nephrology of Latvia, LV-1002 Riga, Latvia"},{"name":"Faculty of medicine, Riga Stradins University, LV-1007 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"134","DOI":"10.1053\/j.ajkd.2012.07.021","article-title":"Uric Acid as a Target of Therapy in CKD","volume":"61","author":"Jalal","year":"2013","journal-title":"Am.
