The lack of benefit of a combination of an angiotensin receptor blocker and calcium channel blocker on contrast-induced nephropathy in patients with chronic kidney disease.

Aim: Contrast-induced nephropathy (CIN) is a relatively common and serious complication, which occurs after the administration of contrast materials to patients. Although the pathophysiology of CIN is not exactly understood, ischemia of the medulla, oxidative stress, and direct toxicity of the contrast material are some of the factors that are implicated for the pathogenesis of CIN. To date, the only therapy that reduces the risk of CIN is volume expansion.

Association between depression, nutritional status, and inflammatory markers in peritoneal dialysis patients.

Background: To investigate the relationship between depression, nutritional status, and inflammatory markers in patients on peritoneal dialysis (PD).

Patients And Methods: This prospective study included 40 PD patients and 20 healthy people. The severity of depressive symptoms was assessed using the Beck depression inventory, the Hamilton depression rating scale, and the Hamilton anxiety rating scale.

Locking tunneled hemodialysis catheters with hypertonic saline (26% NaCl) and heparin to prevent catheter-related bloodstream infections and thrombosis: a randomized, prospective trial.

Objective: Tunneled cuffed dual-lumen catheters (TCCs) are commonly used for vascular access in hemodialysis (HD) patients. Catheter-related bloodstream infection (CRBSI) is the major problem leading to morbidity and mortality. We investigated whether 26% NaCl solution has any favorable effect on the infections and thrombosis caused by HD catheters.

Relationship between depression and proinflammatory cytokine levels in hemodialysis patients.

Aim: To evaluate the presence of the relationship between depression and proinflammatory cytokine levels in hemodialysis (HD) patients.

Methods: The study included 40 HD patients and 20 healthy controls. All participants were evaluated for the presence of depression using the structured clinical interview based on criteria defined by Diagnostic and statistical manual mental disorders (Fourth Edition, Text Revision) Axis I disorders.

Unusual clinic presentation of polyarteritis nodosa: involvement of axillary and brachial artery.

Polyarteritis nodosa (PAN) is a necrotizing inflammatory vasculitis of small- and medium-sized muscular arteries. Multiple organs, especially the kidney, skin, peripheric nerves, striated muscles, and intestine, are affected. In this case report, a patient with renal and hepatic involvement and axillary and brachial artery aneurysm resulting in shoulder hematoma and pain due to underlying PAN is presented.

Brucella glomerulonephritis and prosthetic valve endocarditis: a case report.

Although brucellosis is an endemic disease in Mediterranean countries, there are few reported cases of Brucella endocarditis and glomerulonephritis. We report a case of Brucella prosthetic mitral valve endocarditis and glomerulonephritis that could be managed by using only antibiotic therapy, including rifampicin, doxycycline and ceftriaxone, without a surgical procedure.
