    Introduction: The IRC publications on anemia are extremely numerous and American, European and more recently French recommendations, under the aegis of the French Agency for the Safety of Health Products (AFSSAPS), have been produced on this subject. Definition of anemia of chronic renal failure: The classic definition of anemia in the general population is that…

    Spinal hypoplasia: Anemia is constant during chronic renal failure (CRF), with the exception of polycystic disease. It worsens along with the decrease in glomerular filtration. The main cause is bone marrow hypoplasia, a consequence of renal hyposecretion of erythropoietin (EPO); the other mechanisms are accessory: various deficiencies, chronic hemolysis, plasma inhibitors of erythropoiesis, medullary fibrosis in large…

    INTRODUCTION: Cardiovascular disease is responsible for more than 50% of deaths in patients with renal failure treated with chronic hemodialysis. Heart complications alone account for 40% of mortality. Ventricular hypertrophy and heart failure as well as arterial atheroma are the main causes, while the incidence of pericarditis, a classic complication of terminal uremia, has decreased. UREMIC PERICARDITIS:…

    Introduction : Acute renal failure (ARI) in the renal transplant patient is an acute decrease in glomerular filtration rate (GFR). The IRA in the transplant recipient may be identical in its causes to that of the clean kidneys in a non transplanted subject, with in addition to specific causes related to the dysfunctional kidney transplant state. These…

    Epidemiology: The frequency of acute renal failure (ARI) in pregnancy is very different in developed and developing countries. Prevalence and prognosis data can not be interpreted without taking into account the geographic context in which they were obtained. The IRA has become, in France, an exceptional complication of pregnancy. Its incidence has declined significantly in developed countries…

    INTRODUCTION: In France, the annual incidence of end-stage renal failure is 6 children / 1 million children under 15, ie 1.2 pediatric patients / 1 million inhabitants. Children under 5 represent 26% of patients. CAUSES OF TERMINAL RENAL FAILURE IN CHILDREN: They are in order of frequency renal hypoplasia-dysplasia associated or not with malformation uropathy (36%),…

    Generalities: Acute renal failure (ARF) is a common complication in HIV-positive patients for the human immunodeficiency virus (HIV).It occurs on average 4.5 years after the diagnosis of seropositivity. The etiologies of the IRA are multiple. Acute tubular necrosis of ischemic origin is the leading cause of ARI in HIV patients. It mainly complicates shock and sepsis. It is favored…

    Dr. Taoufik

    Introduction: Acute renal failure (ARI) is defined in general terms as a sudden decrease in renal function, sufficient to lead to nitrogen waste retention and disrupt hydroelectrolytic homeostasis. While this qualitative definition is generally accepted, there is no consensus on the quantitative importance of the decrease in renal function necessary for the diagnosis of ARI. Commonly used…

    Acute renal failure is defined by a rapid decrease (hours to 1-2 weeks) of renal function, constituting an electrolyte imbalance and acid-base brutal. classically There are 3 major groups of acute renal failure (ARF), as the mechanism involved in the infringement: – Functional or Prerenal IRA; – Renal IRA (or organic); – Obstructive or post-renal…
