Comparisons were made using non-parametric statistics, and the correlations assessed using Spearman's correlation coefficient. Data are presented as median [minimum-maximum].<h4>Results</h4>Nineteen hyperthyroid cats were inJournal of feline medicine and surgery1098612X261418859https://www.ebi.ac.uk/biostudies/studies/S-EPMC12924991biostudies-literatureEXPRESS: Changes in serum symmetric dimethylarginine (SDMA) concentrations after treatment of feline hyperthyroidism with anti-thyroid medications.PMC12924991Cox SETarrant ELWilliams TLfalseEXPRESS: Changes in serum symmetric dimethylarginine (SDMA) concentrations after treatment of feline hyperthyroidism with anti-thyroid medications.<h4>Objectives</h4>To report changes in serum creatinine and symmetric dimethylarginine (SDMA) concentrations following treatment of feline hyperthyroidism with anti-thyroid medications and compare these biomarkers at baseline between cats that were and were not azotaemic after treatment.<h4>Methods</h4>Retrospective study; hyperthyroid cats that were euthyroid (total thyroxine concentration (TT4) 7-40 nmol/L) at 1 month (T1) and/or 2-9 months (T2) following treatment were identified and grouped by renal status defined by serum creatinine concentrations post-treatment.
