The Relationship

The relationship between serum uric acid (SUA) and hypertension has been a subject of increasing interest since the 1870 discovery by Frederick Akbar Mahomed. Several epidemiological studies have shown a strong association between high SUA levels and the presence or the development of hypertension. Genetic analyses have found that xanthine oxidoreductase (XOR) genetic polymorphisms are associated with hypertension. However, genetic studies on urate transporters and Mendelian randomization studies failed to demonstrate a causal relationship between SUA and hypertension. Results from clinical trials on the role of urate-lowering therapy in the management of patients with hypertension are not uniform. Our study sought to analyze the prognostic and therapeutic role of SUA in the hypertensive disease, from uric acid (UA) biology to clinical trials on urate-lowering therapies.

The Relationship

C-reactive protein (CRP) and coronary heart disease (CHD) have been the subject of intensive investigations over the last decades. Epidemiological studies have shown an association between moderately elevated CRP levels and incident CHD whereas genetic studies have shown that polymorphisms associated with elevated CRP levels do not increase the risk of ischemic vascular disease, suggesting that CRP might be a bystander rather than a causal factor in the progress of atherosclerosis. Beside all those epidemiological and genetic studies, the experimental investigations also try to reveal the role of CRP in the progress of atherosclerosis. This review will highlight the complex results of genomic, epidemiological, and experimental studies on CRP and will show why further studies investigating the relationship between CRP and atherosclerosis might be needed.

Abstract Hyperuricemia is common in chronic kidney disease (CKD) and may be present in 50% of patients presenting for dialysis. Hyperuricemia can be secondary to impaired glomerular filtration rate (GFR) that occurs in CKD. However, hyperuricemia can also precede the development of kidney disease and predict incident CKD. Experimental studies of hyperuricemic models have found that both soluble and crystalline uric acid can cause significant kidney damage, characterized by ischemia, tubulointerstitial fibrosis, and inflammation. However, most Mendelian randomization studies failed to demonstrate a causal relationship between uric acid and CKD, and clinical trials have had variable results. Here we suggest potential explanations for the negative clinical and genetic findings, including the role of crystalline uric acid, intracellular uric acid, and xanthine oxidase activity in uric acid-mediated kidney injury. We propose future clinical trials as well as an algorithm for treatment of hyperuricemia in patients with CKD.

The Relationship

It has been well documented that there is an increased prevalence of standard cardiovascular (CV) risk factors in association with diabetes and with diabetes-related abnormalities. Hyperglycemia, in particular, also plays an important role. Heart failure (HF) has become a frequent manifestation of cardiovascular disease (CVD) among individuals with diabetes mellitus. Epidemiological studies suggest that the effect of hyperglycemia on HF risk is independent of other known risk factors. Analysis of datasets from populations including individuals with dysglycemia suggests the pathogenic role of hyperglycemia on left ventricular function and on the natural history of HF. Despite substantial epidemiological evidence of the relationship between diabetes and HF, data from available interventional trials assessing the effect of a glucose-lowering strategy on CV outcomes are limited. To provide some insight into these issues, we describe in this review the recent important data to understand the natural course of CV disease in diabetic individuals and the role of hyperglycemia at different times in the progression of HF.

The strong association between alcohol usage and the development of oral cancer (OC) has been reported in numerous papers. As some mouthrinses contain significant amounts of ethanol, a possible relationship to this pathology has been considered. The purpose of the present paper is to analyze several epidemiological studies which evaluated the association between commercial mouthrinses and the etiology of OC. Although some authors report an association, most of the studies are unclear and sometimes contradictory. The controversial aspects regarding the role of alcohol in OC may also make difficult to find a clear relationship between the use of mouthrinses containing alcohol and OC.

The Relationship

Autophagy is a conserved homeostatic mechanism enabling cells to cope with various stresses. The pathways leading up to the activation of autophagy are interconnected with those of tumorigenesis. However, the relationship between the two events is not a straightforward one and very often context-dependent. Generally, autophagy appears to act against the tumor during the initiation stage and most often drives cancer progression subsequently. Published clinical trials for the treatment of various tumors, where autophagy was pharmacologically inhibited, were obtained and tabulated. Targeting autophagy for the treatment of tumors can be rewarding in the appropriate context, such as cancer type, grade, and microenvironment.

Abstract Background Increased uric acid levels have been known to be associated with different cardiovascular and renal diseases.  Over the last few years, several studies have examined the role of urate-lowering therapy (ULT) in hypertension and Major Adverse Cardiac Events (MACE) and results are pointing to a potential role of elevated serum uric acid as an emerging independent cardiovascular risk factor. Objective  To determine if urate-lowering therapy (Febuxostat vs Allopurinol) has an association on blood pressure and MACE among adult patients with hyperuricemia. Methodology Randomized controlled trials with outcomes of blood pressure, all-cause mortality, myocardial infarction, and stroke were searched through PubMed and Cochrane database. Results Pooled analysis of studies on hyperuricemic patients showed that Febuxostat 40 mg has no significant difference compared with Allopurinol 100/300mg with respect to lowering diastolic (MD -0.56 with 95% CI of -4.28 to 3.15) and systolic blood pressure (MD -0.72 with 95% CI of -4.87 to 6.31).  No significant differences were also noted on all-cause mortality (OR 1.21 with 95% CI of 0.35 to 4.12) and myocardial infarction (MI) (OR 1.38 with 95% CI of 0.19 to 9.94). Outcomes on non-fatal stroke were only reported by Becker, et. al (2010) with only 2 events reported in the Febuxostat 80 mg group (0.26%) and no event in the Allopurinol group (CI= 0.082 to 1.155). Conclusion The results of this meta-analysis showed that urate-lowering therapy (Febuxostat vs Allopurinol) has no significant association on blood pressure among adult patients with hyperuricemia.  No significant association was also found with respect to all-cause mortality and MI. Outcomes on stroke were inconclusive since only one study reported on its events.

Obsessive-compulsive disorder (OCD) is a psychiatric disorder in which the patient suffers from recurrent intrusive ideas, impulses, thoughts (obsessions), and/or patterns of behavior (compulsions) that are ego-alien and produce anxiety if resisted. The ego-dystonic nature of OCD is one of the hallmarks of this disorder. OCD can be a disabling condition because the obsessions and compulsions are time-consuming and interfere with patients' everyday activities and their relationships with friends and family. In severe cases, OCD conflicts even with the simplest tasks of daily living.Research interest in OCD has been growing steadily in the past decade. A search on MEDLINE reveals an over 300% increase in citations on OCD from 1986 to 1998. These range across the spectrum of research fields, from genetic studies, brain imaging, and neurobiological research examining the underlying pathogenesis of OCD to epidemiological studies evaluating the course of clinical symptoms, comorbidities, and outcomes. Each area represents an important piece in the complex jigsaw puzzle of OCD.

Abstract Background IgA Nephropathy (IgAN) is one of the most common glomerular diseases. However, the effect of uric acid on the prognosis of IgAN is still unclear, especially between males and females. Therefore, the present study aimed to explore the role of hyperuricemia in IgAN patients and the differences in gender. Consequently, the study conducted a retrospective analysis of the prognosis of IgAN in patients from the General Hospital of Tianjin Medical University. Methods: A total of 1,022 patients with primary IgAN, diagnosed through renal biopsy were enrolled from the Department of Nephrology, General Hospital of Tianjin Medical University. However, after applying the exclusion criteria, only 463 patients remained and were regularly followed up in the hospital. In addition, the relationship between Time Average Uric Acid (TA-UA) and prognosis of IgAN was analyzed. Results: The findings showed that TA-UA was an independent risk factor for the prognosis of IgAN in the 463 patients studied (OR=1.752，95%CI=1.348-2.277，p＜0.001). Additionally, higher TA-UA values were associated with a faster progression of disease and worse prognosis (p < 0.05). Elevated TA-UA was also shown to be an independent risk factor for the progression of disease in female patients but not in their male counterparts (women: HR=1.998，95%CI=1.398-2.854，p＜0.001，men: HR=1.405，95%CI=0.869-2.274, p=0.166). Conclusion: Increased TA-UA is an independent risk factor for the progression of IgAN, especially in women.

Uric Acid Secretion

In humans, the end product of purine metabolism is uric acid. Over 70% of uric acid is excreted through the kidneys. When renal function is impaired, uric acid secretion is also impaired. This directly correlates the prevalence of hyperuricemia with the severity of chronic kidney disease (CKD). It has been reported that the prevalence of hyperuricemia in patients with Stage I-III CKD is 40–60% and up to 70% in patients with Stage IV-V CKD. Some studies found a link between serum uric acid levels and decreased glomerular filtration rate (GFR), an independent risk factor for CKD development. Because CKD and serum uric acid levels are related, the relationship between the two frequently generates controversy. As such, this review of the literature discusses the role of uric acid in the pathogenesis and progression of CKD.
