360: Q192R polymorphism and activity of paraoxonase 1 in high cardiovascular risk subjects on hypolipidemic drugs

Paraoxonase 1 (PON1), a high-density lipoprotein-associated antioxidant enzyme, hydrolyzes several organophosphate pesticides and oxidized lipids. The PON1 Q192R polymorphism affects the catalytic efficiency and is considered a risk factor for pesticide intoxication and cardiovascular disease (CVD) but the association is not consistent between individuals or populations. We aimed to study the association of PON1 Q192R polymorphism with CVD risk in coffee harvesters of central Colombia. Demographics were collected from 205 subjects via standardized questionnaires. Lipid profiles and serum butyrylcholinesterase (BChE) were measured by standard procedures. The calculated 10-year atherosclerotic CVD (ASCVD) risk was used as the cardiovascular risk estimate. Q192R genotype was determined by real-time PCR. Prevalence of hypertension, hypercholesterolemia, and the 10-year ASCVD risk was 33%, 62%, and 22%, respectively. BChE levels were no indicative of recent pesticide exposure, although a positive correlation was observed with BChE and hypercholesterolemia. The Q192R genotype frequencies were 38% (QQ), 44% (QR), and 18% (RR). We found an association of the 192Q genotype with hypertension. The results of this study signal the importance to evaluate the influence and potential interactions of BChE and PON1 192Q allele with known genetic and environmental factors implicated in the pathogenesis of CVD.

A significant number of epidemiological studies have shown that hyperuricemia is highly associated with the risk of developing cardiovascular disease, chronic kidney disease, and diabetes. In this connection, increased attention is required to monitor serum uric acid levels in patients, not only from a rheumatological point of view, but also with regard to reducing cardiovascular and renal risks. This article is a review of studies on the association of hyperuricemia with cardiovascular risk and a new consensus for the management of patients with hyperuricemia and high cardiovascular risk, published in december 2019 by a group of experts of the Russian Medical Society for Arterial Hypertension, which, among other things, includes a management algorithm of this category of patients.

Current Guidelines

The worldwide morbidity and mortality burden of cardiovascular disease (CVD) is overwhelming and caused by increasing life expectancy and an epidemic of risk factors, including hypertension. Therapeutic options targeting different areas of the renin–angiotensin–aldosterone system (RAAS) to disrupt pathophysiological processes along the cardiovascular continuum are available. Angiotensin-converting enzyme (ACE) inhibitors are first-line treatments for CVD and angiotensin receptor blockers (ARBs) are suitable alternatives. Both ACE inhibitors and ARBs prevent CVD by lowering blood pressure (BP). Additionally, several studies have demonstrated that RAAS blockade can reduce cardiovascular risk beyond what might be expected from BP lowering alone. However, the ARBs are not all equally effective. Telmisartan is a long-lasting ARB that effectively controls BP over the full 24-hour period. Recently, the Ongoing telmisartan alone and in combination with ramipril global endpoint trial (ONTARGET) study showed that telmisartan reduces cardiovascular events in high cardiovascular risk patients similarly to the gold standard ACE inhibitor ramipril beyond BP lowering alone, but with a better tolerability. Based on the results of the ONTARGET and Telmisartan randomized assessment study in ACE intolerant subjects with cardiovascular disease (TRANSCEND) studies, telmisartan is indicated for the reduction of cardiovascular morbidity. This article aims to review current guidelines for the management of CVD and consider key data from clinical trials and clinical practice evaluating the role of telmisartan in CVD.
