[Various epidemiological aspects of hyperuricemia and gout in Mexico: incidence and the cardiovascular risk factor]

We studied the prevalence and the risk factor among the patients of gout in Mexico. Research was conducted in the National Institute of Cardiology and in our private practice. Prevalence of hiperuricemia and gout in the Institute of Cardiology was of 1% (970 out of nearly 100,000 patients). We divided those cases of two subgroups: Reumatology patients (333) and Cardiovascular patients (529). In the first group primary gout was (96.3), and (50.32% in the second. Risk factor was quite different too: nephropathy 9.9%, lithiasis 9.3%, pyelonephritis 2.7%, cardioangiosclerosis 12.9%, aortosclerosis 6.6%, coronary insufficiency 6.3%, myocardial infarction 0.9%, arterial hypertension 24.6% obesity 56.1% and diabetes 9.9% in the Reumatology group; in the Cardiovascular one, nephropathy 14.3%, lithiasis 12.2%, pyelonephritis 7.1%, cardioangiosclerosis 62.7%, aortosclerosis 31.7%, coronary insufficiency 24.9%, myocardial infarction 29%, arterial hypertension 51%, obesity 54.8% and diabetes 20.4%. Among the private practice patients prevalence was of 10.1% (961). In an early age (39 years) in men and a later one for women (53 years). Other characteristics of epidemiology and risk factor are: primary gout 89%, atherosclerosis 5%, coronary disease 4.6%, lithiasis 4.7%, nephropathy 2%, pyelonephritis 1%, obesity 43%, and diabetes 4.6%. In an small group of patients of our private practice we made an exhaustive study of risk factor and the metabolic disorder of lipids. We found the following frequency: 9.3 of nephropathy, 31.2% of lithiasis, 18.7% of pyelonephritis, 68.9% of cardioangiosclerosis, 46.8% de coronary insufficiency, 9.3% of myocardial infarction, 68.7% of arterial hypertension, 68.7% of obesity and 18.7% of diabetes. In the lipid profile we found an increase in triglicerids and prebeta lipoprotein. We have amply discussed the relation between hiperuricemia and pathology considered as a risk factor from the genetic point of view as well as the metabolic and circumstancial aspect. From all that we concluded that risk is multifactorial.
