Achievement rate of target blood pressure in patients with hypertension treated by hypertension specialists and non-specialists in a real-world setting.

Hypertension remains a major global healthcare issue. Considering that most Japanese patients with hypertension are managed by general practitioners, hypertension specialists should be involved in actual clinical practice. We investigated the blood pressure (BP), guidelines recommended for achievement rate of the target BP, and clinical variables of patients with hypertension treated by hypertension specialists and those treated by non-specialists in a real-world setting.

Urate-lowering drugs for chronic kidney disease with asymptomatic hyperuricemia and hypertension: a randomized trial.

Introduction: Xanthine oxidase (XO) inhibitors may slow down chronic kidney disease (CKD) progression. The comparative effectiveness of the different urate-lowering drugs is unknown. The aim of this study was to determine whether urate-lowering therapy with an XO inhibitor (febuxostat) and that with a uricosuric drug (benzbromarone) are comparable in slowing renal function decline in patients with CKD complicated with hypertension and hyperuricemia.

Salt and potassium intake evaluated with spot urine and brief questionnaires in combination with blood pressure control status in hypertensive outpatients in a real-world setting.

Reducing salt and increasing potassium intake are recommended lifestyle modifications for patients with hypertension. The estimated 24-h urinary salt excretion value from spot urine using Tanaka's formula and the salt check-sheet scores, questionnaire-based scores of salt intake, are practical indices of daily salt intake. However, few studies have evaluated salt intake with these methods in hypertensive outpatients.

A questionnaire survey to assess lower urinary tract symptoms in patients with chronic stroke.

Objectives: In this study, we evaluated the prevalence of lower urinary tract symptoms and the associated clinical features in patients with chronic stroke.

Methods: Patients with stroke who had been regularly followed up at general medical hospitals in Okinawa, Japan were enrolled in the study. The patients were asked to complete a self-reported questionnaire regarding their physical activity, medical history, and the core lower urinary tract symptom score (CLSS) questionnaire, with anonymity.

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.

Prevalence and Risk Factors for Nocturia in an Outpatient Clinic.

Objectives: We evaluated the prevalence of and risk factors in patients with nocturia at a general medical clinic in Naha, Japan.

Methods: We enrolled patients who had been regularly followed-up at a general medical clinic in Naha. Patients were asked to complete a self-reported questionnaire regarding medical history and the frequency of nocturnal voids in the last month with anonymity.

Beneficial effect of switching from a combination of angiotensin II receptor blockers other than losartan and thiazides to a fixed dose of losartan/hydrochlorothiazide on uric acid metabolism in hypertensive patients.

Among the angiotensin II receptor blockers (ARBs), losartan (LOS) has uricosuric action. The clinical benefits of LOS compared with those of other ARBs may be apparent when it is combined with diuretics, which have an unfavorable influence on serum uric acid (SUA). The effects of switching from combinations of ARBs other than LOS and thiazides to a fixed-dose combination comprising 50 mg LOS and 12.

Switching therapy from variable-dose multiple pill to fixed-dose single-pill combinations of angiotensin II receptor blockers and thiazides for hypertension.

The efficacy and tolerability of switching therapy from free combinations of angiotensin II receptor blocker (ARB) and thiazide (A/T) to a fixed-dose of losartan and hydrochlorothiazide (L/H) has not been evaluated in Japan. We examined effects of switching therapy from variable-dose multiple-pill A/T to a fixed-dose L/H on blood pressure (BP) along with medication adherence and the degree of satisfaction in 91 hypertensive outpatients (mean age, 65.2 ± 9.

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.

Role of HCN4 channel in preventing ventricular arrhythmia.

Bradycardia is a trigger of ventricular arrhythmias in patients with arrhythmia including Brugada syndrome and long QT syndrome. The HCN4 channel controls the heart rate, and its mutations predispose to inherited sick sinus syndrome and long QT syndrome associated with bradycardia. We found a 4 base-insertion at the splice donor site of the HCN4 gene in a patient with idiopathic ventricular tachycardia, which was supposed to generate a truncated channel.

[A case of hemodynamic brain infarction with postprandial hypotension].

A 76-year-old man with left internal carotid artery occlusion developed a progressing right hemiparesis. Brain MRI presented reinfarctions in the left anterior border zone and terminal zone in the left deep white matter. Ambulatory blood pressure monitoring showed a decrease in systolic blood pressure by more than 20 mmHg one hour after starting meals, which is considered as postprandial hypotension.

Evidence for elevated pulse pressure in patients on chronic hemodialysis: a case-control study.

Background: Few analyses have compared pulse pressure (PP) values in hemodialysis patients with healthy individuals, and they have provided only limited data. We retrospectively examined PP in a large cohort of hemodialysis patients and healthy control subjects.

Methods: The relationships of systolic blood pressure (SBP), diastolic blood pressure (DBP), and PP to mean arterial pressure (MAP) levels were investigated in 234 chronic hemodialysis patients and in 682 control subjects matched for age, sex, diabetes mellitus, and body mass index.

Severe abdominal pain associated with allergic reaction to nafamostat mesilate in a chronic hemodialysis patient.

A 33-year-old woman was referred from an outside dialysis clinic to our hospital because of severe abdominal pain during hemodialysis. She had been on chronic hemodialysis for the past 11 years due to chronic glomerulonephritis. Nafamostat mesilate was used as an anticoagulant for hemodialysis, because it was during her menstrual period with hypermenorrhea.

Analysis of drug prescription in chronic haemodialysis patients.

Background: Information concerning medication use in Asian haemodialysis patients is sparse. We surveyed prescribed medications and examined the relation between the number of medications and mortality and clinical characteristics in chronic haemodialysis patients, in Okinawa, Japan.

Methods: We conducted a cross-sectional multicentre survey in August 1999 and patients were observed during 13 months of follow up.

End-stage renal disease associated with familial Mediterranean fever.

A 39-year-old man had been suffering from periodic fever since childhood. He was started on hemodialysis due to secondary amyloidosis on December 2000. The patient was believed to have Familial Mediterranean fever (FMF) because of recurrent fever with peritonitis, arthritis and inflammatory changes and secondary amyloidosis in his kidneys, heart and colon.

A patient with adult-onset type II citrullinemia on long-term hemodialysis: reversal of clinical symptoms and brain MRI findings.

A 40-year-old woman was referred for several episodes of coma lasting from 2 hours to 2 days. She had been on maintenance hemodialysis for polycystic kidney disease for 9 months. Laboratory findings showed high serum levels of ammonia and citrulline, and a diagnosis of adult-onset type II citrullinemia was made.
