    Renal manifestations of systemic autoimmune diseases

    Introduction: Systemic autoimmune diseases can have severe kidney involvement.Renal involvement may be clinically silent, but may also cause serious permanent damage that is extremely damaging to the patient. This is why great vigilance is required vis-à-vis the renal involvement in any systemic disease involving this risk. In this article, we will review current knowledge about renal…

  • Acute renal failure during HIV infection

    Acute renal failure during HIV infection

    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…

  • Clinical and biological diagnosis of acute renal failure

    Clinical and biological diagnosis of acute renal failure

    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…

    GLOMÉ RULES AND GLOBAL FILTRATION: Constitution of the primitive urine: Renal blood flow accounts for 20% of the cardiac output and crosses almost all the glomeruli. The first step in the development of urine is the formation of the glomerular ultrafiltrate by diffusion of the plasma components through the glomerular filtration barrier. This diffusion is done as…

  • Measurement of renal function by radioisotopic methods

    Measurement of renal function by radioisotopic methods

    Introduction: Renal function: which parameter to choose? If the nature of kidney function were to be defined, it would probably be considered that the main role of the kidney is to maintain homeostasis of the inner environment. However, there is no obvious parameter that directly quantifies this role. In addition, the kidney also has a distinct metabolic…

  • Exploration of renal tubular functions

    Exploration of renal tubular functions

    Introduction: The vital role of the kidneys is intimately linked to their function in the homeostasis of the internal environment, thus protecting the cells from the consequences of environmental variations of the organism. The kidneys eliminate the terminal metabolic products (urea, protons, uric acid, creatinine, bilirubin, etc.), a large number of exogenous substances such as certain…

    Renal biopsy: techniques

    History of renal biopsy: The kidney was one of the last full organs explored by percutaneous puncture-biopsy. For this deep organ, there was not only a risk of hemorrhagic complications of the kidney itself but also injury to another intra- or retroperitoneal organ (pancreas, colon, spleen, liver, suprarenal, large vessels, etc.). .). This injury could lead to…

  • Renal biopsy: contraindications, complications

    Renal biopsy: contraindications, complications

    Introduction: Renal biopsy is an essential step in the study of kidney disease. It provides indispensable histological arguments which create the basis for the nosology of nephropathies, in particular glomeruli. Immunological marking and molecular biology studies have helped to clarify the clinical and histological individualization of kidney disease and have opened up many possibilities for their pathogenic…

  • Acute Renal Failure

    Acute Renal Failure

    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…

  • Renal Tissue recreated stem cells

    Renal Tissue recreated stem cells

    Japanese researchers said they were able to develop for the first time kidney tissue from induced pluripotent stem cells (iPS). This is an important step that has just revealed a report released today: A team of Japanese scientists led by Kenji Osafune, managed to develop kidney tissue with a success rate of over 90% after…
