Bright's disease is a historical classification of kidney diseases that would be described in modern medicine as acute or chronic nephritis. It was characterized by edema, the presence of albumin in the urine and was frequently accompanied by high blood pressure (hypertension).
The symptoms and signs of Bright's disease were first described in 1827 by the English physician Richard Bright, after whom the disease was named. In his Reports of Medical Cases, he described 25 cases of dropsy (edema) which he attributed to kidney disease. Symptoms and sign included: inflammation of serous membranes, hemorrhages, apoplexy, convulsions, blindness and coma. Many of these cases were found to have albumin in their urine (detected by the spoon and candle-heat coagulation), and showed striking morbid changes of the kidneys at autopsy. The triad of dropsy, albumin in the urine and kidney disease came to be regarded as characteristic of Bright's disease. Subsequent work by Bright and others indicated an association with cardiac hypertrophy, which was attributed by Bright to stimulation of the heart. Subsequent work by Mahomed showed that a rise in blood pressure could precede the appearance of albumin in the urine, and the rise in blood pressure and increased resistance to flow was believed to explain the cardiac hypertrophy.
