Physiological changes during hemodialysis in patients with intradialysis hypertension

Changes in Plasma Copeptin Levels during Hemodialysis: Are the Physiological Stimuli Active in Hemodialysis Patients?

OBJECTIVES Plasma levels of copeptin, a surrogate marker for the vasoconstrictor hormone arginine vasopressin (AVP), are increased in hemodialysis patients. Presently, it is unknown what drives copeptin levels in hemodialysis patients. We investigated whether the established physiological stimuli for copeptin release, i.e. plasma osmolality, blood volume and mean arterial pressure (MAP), are op...

Pulmonary Hypertension in Hemodialysis Patients

Hemodynamic and hormonal changes during erythropoietin therapy in hemodialysis patients.

To better understand the mechanism of recombinant human erythropoietin (rhEPO)-induced increase in BP, hemodynamic parameters, body fluid volumes, and the hormones implicated in BP regulation were studied in 32 anemic hemodialysis patients before and after 3 to 4 mo of rhEPO therapy. Hemoglobin levels increased from 83 +/- 1.5 to 119 +/- 2.3 g/L (P < 0.01) after rhEPO therapy (25 to 43 U/kg) ad...

Dentomaxillofacial Radiographic Changes in a Group of Iranian Patients with End Stage Renal Disease Undergoing Hemodialysis

Introduction: This study aims to evaluate the dentomaxillofacial radiographic changes in end stage renal disease (ESRD) patients who were on hemodialysis. Methods: Parathyroid hormone (PTH), calcium, phosphorus and alkaline phosphatase (ALP) measurements, as well as Panoramic and periapical radiographs were obtained from seventy four patients with a history of end stage renal disease (ESRD). Re...

Frequency of Pulmonary Hypertension in Hemodialysis Patients

OBJECTIVE Pulmonary hypertension (PH) has been described in hemodialysis (HD) patients and has been associated with increased morbidity and mortality. Our objective was to determine the prevalence of pulmonary hypertension in patients on regular hemodialysis. METHODS This cross sectional study was conducted in Department of Nephrology, Liaquat National Hospital Karachi from April 2013 to Marc...
