Nephrology and Hypertension

Acute kidney injury (AKI) is a clinical syndrome that complicates the course and worsens the outcome in a significant number of hospitalised patients. Recent advances in clinical and basic research will help with a more accurate definition of this syndrome and in the elucidation of its pathogenesis. Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood's chemical makeup may get out of balance.Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly, usually in less than a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care.

Immunosuppression (IS) is administered to kidney transplant recipients to prevent rejection episodes and loss of the renal allograft. Most centers rely on a triple IS after induction with either interleukin‑2 receptor antibodies or antithymocyte globulin. The most frequently used substances for maintenance IS are glucocorticoids, antimetabolites, mTOR inhibitors (mTORi), calcineurin inhibitors (CNI) and the costimulation blocker belatacept. Guidelines recommend a triple combination consisting of CNIs, antimetabolites and corticosteroids for the majority of patients. The long-term risk for malignancy in general is increased in solid organ recipients compared to the general population. Modification of IS may result in reduced risk for non-melanoma skin cancers but results in higher graft rejection rates and in the case of mTORi, deaths. In the case of posttransplantation lymphoproliferative disorders (PTLD) treatment options are reduction of IS, rituximab, chemotherapy, radiation therapy or a combination of these. The optimal protocol has not yet been established and depends on patient age and status, tumor load, laboratory findings, organ functions (heart, kidney, liver) and PTLD subtype. Posttransplantation diabetes mellitus is a frequent complication after kidney transplantation. Tacrolimus more than cyclosporine A.

Renal hypertension (or renovascular hypertension) is high blood pressure caused by the narrowing of your arteries that carry blood to your kidneys. It is also sometimes called renal artery stenosis. Because your kidneys are not getting enough blood, they react by making a hormone that makes your blood pressure rise. Blood pressure is the force of blood against your artery walls as your heart pumps blood through your body. A reading of 120/80 mmHg, or “120 over 80,” is normal. A reading of 140/90 mmHg or above is considered high blood pressure.

Renal hypertension is caused by a part or total bock of the arteries that supply blood to your kidneys. These renal (kidney) arteries carry blood rich in oxygen and nutrients from your heart to your kidneys. If your kidneys do not get enough blood or oxygen, it may be because these renal arteries are narrowed, a condition called renal artery stenosis. Plaque, made up of fat, cholesterol, calcium and other substances, builds up inside your arteries and causes them to harden and narrow (stenosis). Plaque can block, either partially or totally, your blood's flow through an artery in the heart, brain, pelvis, legs, arms or kidneys.

Pediatric Nephrology is a specialized field within medicine that focuses on kidney health and diseases in children.

Studying the physiology of the kidney is known as renal physiology (Latin: rns, "kidneys"). The maintenance of acid-base balance, fluid balance, sodium, potassium, and other electrolytes regulation, toxin removal, absorption of glucose, amino acids, and other small molecules, blood pressure control, production of various hormones, including erythropoietin, and vitamin D activation are all included in this.The nephron, the smallest functional unit of the kidney, is the unit of study for a large portion of renal physiology. Each nephron starts with a filtration unit that cleans the blood before it enters the kidney. The filtrate then moves along the length of the nephron, a tubular organ lined with a single layer of specialized cells and encircled by capillaries.

The kidneys perform a variety of physiological tasks in addition to eliminating uremic poisons. They serve to maintain acid-base balance, balance electrolytes and water, create erythropoietin, and are essential for bone and mineral metabolism. Kidneys have various distinct anatomical and ultrastructural properties that enable them to perform these wide-ranging tasks. To detect the make-up of bodily fluids and react to physiologic changes, the various functions also need diverse specialized cells. Some molecules cannot travel via the glomerulus or through the renal tubules, while other molecules are transported into and out of the urine through the media of other cell types. The kidney can be harmed by a wide variety of genetic, hemodynamic, chemical, viral, and autoimmune insults because of its wide spectrum of activities.

Nephrotic lupus: A multisystem, autoimmune connective tissue illness with a wide range of clinical manifestations is systemic lupus erythematosus (SLE). The gender ratio of those affected is 9:1, and the majority of cases occur between the second and fifth decades of life. The intensity and signs of the disease vary greatly, and it is linked to significant morbidity and early death.

Congestive heart failure: Acute decompensated heart failure (ADHF) accounts for 90% of the more than 1 million annual hospitalizations for congestive heart failure (CHF) . The economic burden of CHF in the United States continues to rise, with annual costs of more than 33.2 billion dollars [60]. Pre-existing or worsening renal failure is commonly associated with ADHF and in fact may precipitate decompensation . The frequent occurrence of combined cardiac and renal dysfunction in CHF, whereby one organ failure

A set of diseases known as dysproteinemias are defined by an excessive synthesis of a monoclonal (M) protein as a result of aberrant clonal growth of plasma cells. An immunoglobulin fragment (light chain or heavy chain) or a whole immunoglobulin can both be this M protein. These conditions are collectively referred to as "dysproteinemias," "paraproteinemias," or "monoclonal gammopathies" and include multiple myeloma, light-chain amyloidosis, monoclonal gammopathy of uncertain significance, and others.
