Efficacies of Controlling Morning Blood Pressure and Protecting the Kidneys by Treatment With Valsartan and Nifedipine CR or Valsartan and Amlodipine (MONICA Study).

Background: It is controversial whether a single-pill fixed-dose combination of angiotensin II type 1 receptor blocker and calcium channel blocker (CCB) is effective for all types of hypertension.

Methods: Thirty-five patients with uncontrolled blood pressure (BP) under treatment with valsartan 80 mg/day or amlodipine 5 mg/day were enrolled. They were randomly divided into two treatment groups: a single-pill fixed-dose combination of valsartan 80 mg/day and amlodipine 5 mg/day in the morning (VA group), or valsartan 80 mg/day in the morning and nifedipine CR 20 mg/day at night (VN group), and treated for 16 weeks.

A case of infectious endocarditis-associated crescentic glomerulonephritis with intracranial hemorrhage.

A 55-year-old woman was admitted to our hospital because of fever and renal impairment. The patient had undergone a tooth extraction 11 months prior to admission. Echocardiography demonstrated vegetation on the mitral valve, and Streptococcus mitis was detected on blood culture.

[A randomized controlled trial of postoperative adjuvant chemotherapy for colorectal cancer-optimal duration of the treatment].

Methods: Subjects were 239 patients with colorectal cancer who underwent curative resection surgery from December 1994 to March 1997(Stage I-III b). The patients were given 5'-DFUR for postoperative 10 months as scheduled. They had been allocated into either a 1-year group or a 3-year group by dynamic randomization.

Successful steroid treatment in a patient with membranoproliferative glomerulonephritis associated with hepatitis C virus.

Thirteen years ago, a 65-year-old woman was diagnosed to have chronic active hepatitis with hepatitis C virus. After starting interferon alpha administration, she noticed edema and hypoalbuminemia. Renal biopsy revealed mesangial proliferation with focal endocapillary proliferation, and double contour of the glomerular basement membrane due to mesangial interposition.

Role of amyloidosis in determining the prognosis of dialyzed patients with rheumatoid arthritis.

The role of secondary amyloidosis in determining the prognosis of dialyzed patients with rheumatoid arthritis (RA) was examined in 22 patients with a mean age of 60.1 years included 21 renal amyloidosis. RA duration until the start of dialysis was 19.

LDL apheresis for cholesterol embolism following coronary artery bypass graft surgery--a case report.

A 76-year-old man without any prior history of abnormal urinalysis findings or renal insufficiency demonstrated mild renal dysfunction after coronary bypass graft surgery (CABG). Two months after CABG, pain and blueness in the toes (blue toe syndrome) appeared and, the serum creatinine level (S-Cr) increased from 1.2 to 2.

Successful treatment of six patients with neuroleptic malignant syndrome associated with myoglobulinemic acute renal failure.

Neuroleptic malignant syndrome is a rare but potentially lethal, rare reaction to neuroleptics which is characterized by altered levels of consciousness, extrapyramidal effects, autonomic instability, hyperthermia, and elevated serum creatine phosphokinase levels. The most serious complication of neuroleptic malignant syndrome is acute renal failure. We investigated six cases of neuroleptic malignant syndrome associated with myoglobulinemic acute renal failure due to rhabdomyolysis and effect of hemodialysis or hemodiafiltration.

Effects of thyroid function on the course of experimental chronic renal failure in rats.

Thyroid hormone has been reported to affect renal function. To investigate the effects of thyroid hormone on the progression of renal deterioration, thyroid hormone (dried thyroid) and an antithyroid drug (thiamazole) were administered to adriamycin (ADR)-induced renal failure rats. The rats were divided into four groups, including 1) ADR-DT, given dried thyroid and thiamazole; 2) ADR-T, given thiamazole; 3) ADR; and 4) control.

Impact of interferon-gamma and interleukin-4 gene polymorphisms on development and progression of IgA nephropathy in Japanese patients.

Background: Cytokines have an important role in the pathogenesis and disease progression of immunoglobulin A (IgA) nephropathy. The aim of this study is to investigate the impact of gene polymorphisms of T helper cell subtype 1 (T(H)1)/T(H)2 cytokines, interferon-gamma (IFN-gamma), and interleukin-4 (IL-4) on IgA nephropathy in Japanese patients.

Methods: We investigated IFN-gamma gene (IFNG) and IL-4 gene (IL4) polymorphisms in 96 patients with biopsy-confirmed IgA nephropathy who were followed-up for more than 3 years in our outpatient clinic and 61 healthy controls by polymerase chain reaction and direct sequencing methods.

Different effects of 22-oxacalcitriol and calcitriol on the course of experimental chronic renal failure.

Calcitriol, 1,25(OH)(2)D(3), has been reported to have a beneficial effect on bone histology in patients with predialysis chronic renal failure; however, such treatment involves a risk of hypercalcemia. To investigate the effects of 1,25(OH)(2)D(3) and 22-oxacalcitriol (OCT) on the progression of histologic deterioration, we administered intraperitoneal 1,25(OH)(2)D(3) or OCT, three times a week, to rats with adriamycin-induced progressive renal failure, from the 10th week after the induction of ADR-induced nephropathy. The rats were divided into the following groups: (1) high-dose 1,25(OH)(2)D(3), 0.

Locally activated renin-angiotensin system associated with TGF-beta1 as a major factor for renal injury induced by chronic inhibition of nitric oxide synthase in rats.

Chronic inhibition of nitric oxide synthase (NOS) is known to cause renal parenchymal injury with systemic hypertension. To elucidate the pathogenetic mechanism in renal damage induced by NOS inhibition, N(omega)-nitro-L-arginine methyl ester (L-NAME) was given orally for 12 wk in Wistar rats, and the roles of tissue renin-angiotensin system and transforming growth factor-beta1 (TGF-beta1) were investigated. BP and urinary protein excretion increased significantly in L-NAME rats compared with control rats, and glomerulosclerosis and interstitial fibrosis developed.
