  • Goodpasture syndrome

    serch.it?q=Goodpasture-syndrome

    Goodpasture syndrome (GPS), also known as anti-glomerular basement membrane disease, is a rare autoimmune disease in which antibodies attack the basement membrane in lungs and kidneys, leading to bleeding from the lungs and kidney failure. It is thought to attack the alpha-3 subunit of type IV collagen, which has therefore been referred to as Goodpasture's antigen. Goodpasture syndrome may quickly result in permanent lung and kidney damage, often leading to death. It is treated with medications that suppress the immune system such as corticosteroids and cyclophosphamide, and with plasmapheresis, in which the antibodies are removed from the blood. The disease was first described by an American pathologist Ernest Goodpasture of Vanderbilt University in 1919 and was later named in his honor.

  • Kidney failure

    serch.it?q=Kidney-failure

    Kidney failure, also known as end-stage kidney disease, is a medical condition in which the kidneys no longer function. It is divided into acute kidney failure (cases that develop rapidly) and chronic kidney failure (those that are long term). Symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, or confusion. Complications of acute disease may include uremia, high blood potassium, or volume overload. Complications of chronic disease may include heart disease, high blood pressure, or anemia. Causes of acute kidney failure include low blood pressure, blockage of the urinary tract, certain medications, muscle breakdown, and hemolytic uremic syndrome. Causes of chronic kidney failure include diabetes, high blood pressure, nephrotic syndrome, and polycystic kidney disease. Diagnosis of acute disease is often based on a combination of factors such as decrease urine production or increased serum creatinine. Diagnosis of chronic disease is typically based on a glomerular filtration rate (GFR) of less than 15 or the need for renal replacement therapy. It is also equivalent to stage 5 chronic kidney disease. Treatment of acute disease typically depends on the underlying cause. Treatment of chronic disease may include hemodialysis, peritoneal dialysis, or a kidney transplant. Hemodialysis uses a machine to filter the blood outside the body. In peritoneal dialysis specific fluid is placed into the abdominal cavity and then drained, with this process being repeated multiple times per day. Kidney transplantation involves surgically placing a kidney from someone else and then taking immunosuppressant medication to prevent rejection. Other recommended measures from chronic disease include staying active and specific dietary changes. In the United States acute disease affects about 3 per 1,000 people a year. Chronic disease affects about 1 in 1,000 people with 3 per 10,000 people newly develop the condition each year. Acute disease is often reversible while chronic disease often is not. With appropriate treatment many with chronic disease can continue working.

  • Shortness of breath

    serch.it?q=Shortness-of-breath

    Shortness of breath, also known as dyspnea, is the feeling that one cannot breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of the distinct sensations, the degree of distress involved, and its burden or impact on activities of daily living. Distinct sensations include effort/work, chest tightness, and air hunger (the feeling of not enough oxygen). Dyspnea is a normal symptom of heavy exertion but becomes pathological if it occurs in unexpected situations or light exertion. In 85% of cases it is due to asthma, pneumonia, cardiac ischemia, interstitial lung disease, congestive heart failure, chronic obstructive pulmonary disease, or psychogenic causes, such as panic disorder and anxiety. Treatment typically depends on the underlying cause.
