THU0518 New Cardiovascular Risk Factors Screening in Patients with Gout

BackgroundGout is a disease triggered by the crystallization of uric acid in the joints secondary to persistent hyperuricemia, that leads to chronic inflammation. Patients with gout frequently have comorbidities including cardiovascular (CV) disease, kidney failure, diabetes mellitus etc. In fact, some these can increase the levels of uric acid and contribute to develop gout, and also deteriorate the CV profile of these patients. Therefore, their control and identification is essential for a proper management.ObjectivesTo assess the prevalence of unknown cardiovascular risk factors (CVRF) in patients with gout.MethodsCross-sectional analysis of a inception cohort of gout patients recruited by consecutive sampling in our rheumatology unit. Gout was diagnosed by visualization of monosodium urate crystals in synovial fluid or tophus sample. A structured CV assessment included CVRF, measurement of blood pressure, anthropometry and lab tests. Arterial Hypertension (AH) was defined by previous diagnosis, blood pressure ≥140/90mmHg and/or use of antihypertensive agents. Type 2 Diabetes Mellitus (DM-2) was defined by previous diagnosis, fasting blood glucose ≥126 mg/dL, glycosylated hemoglobin ≥6.5%; presence of microangiopathic complications was also registered. Dyslipidemia (DLP) was defined by previous diagnosis, use of hypolipidemic agents, or total cholesterol>200 mg/dL and/or triglycerides >150 mg/dL. A descriptive analysis of the results is presented.ResultsThe study involved 199 patients. The mean age was 63.4 (SD ±13.2) years, with 171 (85.9%) men. At inclusion the prevalence of CVRF was: AH in 136 patients (68.3%), DLP in 13 (51.8%), and DM-2 in 47 (23.6%). Seventy-six (38.6%) were found obese, smoking background was present in 40 (20.1%), use of diuretics (loop and/or thiazide) in 87 (43.7%), and chronic renal failure in 57 (28.6%). After structured assessment, the following undiagnosed CVRF were found: DLP in 59 patients (29.6%), AH in 20 (10.1%) and DM-2 in 14 (7%). New CVRF were found in 94 (46.7%) patients, among them 52 (26.1%) had one CVRF, 13 (6.5%) had 2 CVRF, and even 3 CVRF were identified in 2 cases (1.0%). The final prevalence of CVRF in included gout patients is shown in the Figure.ConclusionsHalf of our patients showed at least one unknown CVRF, mostly DLP followed by hypertension and DM-2. This finding highlights the need for active screening for new CVRF in patients diagnosed with gout, due to the potential impact on the proper CV manage
