Association of blood pressure and hyperuricemia with proteinuria and reduced renal function in the general population.

This study aimed to investigate the effect of hyperuricemia (HU) on the association of systolic blood pressure (SBP) with the prevalence of proteinuria and low estimated glomerular filtration rate (eGFR) in the general population. This cross-sectional study enrolled 24,728 Japanese individuals (11,137 men and 13,591 women) who underwent health checkups in 2010. The prevalence of proteinuria and low eGFR (< 60 mL/min/1.

Augmented Association Between Blood Pressure and Proteinuria in Hyperuricemic Patients With Nonnephrotic Chronic Kidney Disease.

Background: Hyperuricemia (HU) may enhance susceptibility to hypertensive renal damage via disrupted autoregulation of glomerular hemodynamics. The effect of HU on the association between blood pressure (BP) and proteinuria remains unknown in patients with chronic kidney disease (CKD).

Methods: In total, 109 patients with nonnephrotic CKD (55 men and 54 females) who underwent renal biopsy were recruited.

Effects of xanthine oxidase inhibitors on renal function and blood pressure in hypertensive patients with hyperuricemia.

Hyperuricemia may promote the progression of hypertension and renal dysfunction. However, the effects of hyperuricemia treatment on blood pressure and renal function in adult hypertensive patients with hyperuricemia remain unclear. A total of 137 hypertensive patients with hyperuricemia (96 men and 41 women; mean age of 67 years) who recently started taking xanthine oxidase inhibitors (allopurinol or febuxostat) as outpatients were recruited.

Associations between serum uric acid levels and the incidence of hypertension and metabolic syndrome: a 4-year follow-up study of a large screened cohort in Okinawa, Japan.

The purpose of this study was to examine the associations between serum uric acid (SUA) levels and the incidences of hypertension and metabolic syndrome (MetS) in a large screened cohort of Japanese men and women. We evaluated 4812 subjects (males, 2528; females, 2284; mean age, 47.5 years) who underwent health checkups between 2006 and 2010 and were free of hypertension and MetS in 2006.

Effective treatment of congestive heart failure using adaptive servo-ventilation in an end-stage renal disease patient on hemodialysis.

A 61-year-old man who was being treated with hemodialysis (HD) for end-stage renal disease presented with symptoms of severe congestive heart failure (CHF). Removing excess intravascular fluid during HD was difficult due to the patient's chronic hypotension induced by severe left ventricular (LV) dysfunction. The application of adaptive servo-ventilation (ASV) increased the patient's cardiac output and blood pressure during HD, thus resulting in the effective removal of excess intravascular fluid.

Hyperuricemia predicts future metabolic syndrome: a 4-year follow-up study of a large screened cohort in Okinawa, Japan.

The aim of this study was to determine whether hyperuricemia could predict future metabolic syndrome (MetS) in a large screened cohort of Japanese male and female subjects. We evaluated 5936 subjects (3144 male subjects, 2792 female subjects; mean age 48.7 years) who underwent health checkup programs in 2006 and 2010, who were MetS free in 2006.

Hypertriglyceridemia accompanied by increased serum complement component 3 and proteinuria in non-nephrotic chronic kidney disease.

Background: Hypertriglyceridemia (hTG) is a risk factor for progression of chronic kidney disease (CKD); however, it remains unknown whether the adipocytokine complement component 3 (C3) is involved in the association between hTG and CKD.

Methods: The study included 138 patients (54 % male) with non-nephrotic (serum albumin ≥3 g/dl) CKD who had undergone a renal biopsy and did not have hypocomplementemic disease. Renal arteriolopathy was assessed semi-quantitatively.

An association between uric acid levels and renal arteriolopathy in chronic kidney disease: a biopsy-based study.

Uric acid (UA) can induce renal arteriolopathy in animal models. Whether there is an association between UA and renal arteriolopathy in patients with chronic kidney disease (CKD) is unknown. Here, we examined the cross-sectional association of serum UA levels with renal arteriolar hyalinosis and wall thickening.

Penicillin G-induced hemorrhagic cystitis with hydronephrosis.

Irritable urological symptoms with gross hematuria and bilateral lumbar pain developed when the patient received penicillin G for endocarditis. These symptoms were followed by renal insufficiency. A contrast-enhanced abdominal computed tomography (CT) scan revealed a thickened bladder wall, bilateral hydroureter and hydronephrosis, suggesting hemorrhagic cystitis complicated with urinary tract obstruction.

Proteinuria as a significant determinant of hypertension in a normotensive screened cohort in Okinawa, Japan.

To evaluate the influence of proteinuria on the development of hypertension in normotensive screened subjects. We studied 4,428 normotensive subjects without heart disease (2888 men, 1540 women, age 19-89 years) who were participants in a 1-day health evaluation in both 1997 and 2000. The 3-year frequency of developing hypertension was 6.

Hyperuricemia as a predictor of hypertension in a screened cohort in Okinawa, Japan.

Several epidemiological studies have shown a positive association between serum uric acid levels and the risk of hypertension. However, subjects in these studies were mostly men, or were incompletely examined for lifestyle-related variables. We prospectively examined the relation between hyperuricemia and the risk of developing hypertension with consideration for alcohol consumption and smoking habits in a large screened cohort of men and women.

Hyperuricemia and cardiovascular risk factor clustering in a screened cohort in Okinawa, Japan.

The relation between serum uric acid level and cardiovascular risk factors is complex and has been investigated mainly in men. We examined the correlation between serum uric acid level and obesity, hypertension, dyslipidemia, and diabetes mellitus (DM) in both men and women of a screened cohort in Okinawa, Japan. A total of 9,914 individuals (6,163 men and 3,751 women ranging in age from 18 to 89 years) who were screened at Okinawa General Health Maintenance Association were subjects in this study.

Cardiovascular risk factors associated with pulse pressure in a screened cohort in Okinawa, Japan.

We evaluated the association between pulse pressure (PP) and cardiovascular risk factors in a screened cohort. Individuals who were receiving medications for hypertension or heart disease, who had no ECG record, or who had a record of arrhythmia were excluded. In total, 8,508 subjects (5,299 men and 3,209 women; age range, 18 to 89 years) were studied.
