As compared to the current drugs used in gout treatment, metformin (Met) has the potential advantage of targeting multiple aspects of the disease. The study <strong>aims</strong> to investigate the effect of Met on SUA levels in gout patients with T2DM.</p> <p><strong>Materials and methods. </strong>A retrospective analysis of medical records was carried out on 208 gout patients with Т2DM ≥18 years with at least one year of follow-up treatment in the rheumatology department. The survey was divided into 2 groups: Met group (n=107) – gout patients received Met (1000-2500 mg/daily) and control group (n=101) – gout patients received other peroral hypoglycemic therapy.</p> <p><strong>Results. </strong>Analysis of the baseline parameters in the groups of gout patients showed that Met users were somewhat younger (60 (58.72±9.73) and 61 (60.9±9.4), respectively) (P&lt;0.02) and had better renal function ((Me 60 [50-70] and 50 [44-66], respectively) (P&lt;0,005) compared to non-Met users. The vast majority of patients in both groups had more than two joints affected (79.4 and 83.2%, respectively). The drug of the choice to start urate-lowering therapy in most cases was allopurinol (98.1 and 98.0%, respectively). After one year, gout patients in the Met group showed a significant decrease in SUA levels from (468.9±61.9) to (318.7±44.9) μmol/L (P&lt;0.0001). Within one year, 63.6% of the Met group had reached target SUA levels compared to 47.5% in the control group (P&lt;0.023). The achievement of a significant decrease in fasting blood IRI (from 28.1 [12.8; 49.2] to 19.1 [11.5; 45.8] μmol/L (P&lt;0.01), the HOMA-IR (from 3.5 [1.7; 9.1] to 2.8 [1.4; 9.2] (P&lt;0.01) in patients Met group. The mean incidence of gout attacks was 2.02 per year (95% CI (1.28-2.36)) in the Met group and 4.00 per year (95% CI (2.56-5.42)) in the control group (P&lt;0.01). The mean daily dosages of allopurinol at target for the Met group and control group did not differ significantly and amounted to (258±120) and (246±110) mg, respectively.</p> <p><strong>Conclusions: </strong>The use of a combination of metformin plus urate-lowering therapy (allopurinol) in gout patients with type 2 diabetes mellitus allows to achieve the target of serum urine acid level in 64% of patients; helps to reduce the severity of insulin resistance and significantly associated with a lower incidence of gout attacks.</p>}, number={4}, journal={Problems of Endocrine Pathology}, author={Mykytyuk, Myroslava and Chernyaeva, Anna and Karachentsev, Yurii}, year={2022}, month={Dec.}, pages={61-66} }
