History
The first reports of renal failure occurring in individuals with chronic liver diseases were from the late 19th century by Frerichs and Flint. However, the hepatorenal syndrome was first defined as acute renal failure that occurred in the setting of biliary surgery. The syndrome was soon re-associated with advanced liver disease, and, in the 1950s, was clinically defined by Sherlock, Hecker, Papper and Vessin as being associated with systemic hemodynamic abnormalities and high mortality. Hecker and Sherlock specifically identified that individuals with HRS had low urinary output, very low sodium in the urine, and no protein in the urine. Murray Epstein was the first to characterize splanchnic vasodilation and renal vasoconstriction as the key alterations in hemodynamics in patients with the syndrome. The functional nature of the renal impairment in HRS was crystallized by studies demonstrating that kidneys transplanted from patients with hepatorenal syndrome returned to function in the new host, leading to the hypothesis that hepatorenal syndrome was a systemic condition and not a renal disease. The first systematic attempt to define hepatorenal syndrome was made in 1994 by the International Ascites Club, a group of liver specialists. The more recent history of HRS has involved elucidation of the various vasoactive mediators that cause the splanchnic and renal blood flow abnormalities of the condition.

Famous quotes containing the word history:
“We don’t know when our name came into being or how some distant ancestor acquired it. We don’t understand our name at all, we don’t know its history and yet we bear it with exalted fidelity, we merge with it, we like it, we are ridiculously proud of it as if we had thought it up ourselves in a moment of brilliant inspiration.”
—Milan Kundera (b. 1929)
“I feel as tall as you.”
—Ellis Meredith, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 14, by Susan B. Anthony and Ida Husted Harper (1902)
“No one can understand Paris and its history who does not understand that its fierceness is the balance and justification of its frivolity. It is called a city of pleasure; but it may also very specially be called a city of pain. The crown of roses is also a crown of thorns. Its people are too prone to hurt others, but quite ready also to hurt themselves. They are martyrs for religion, they are martyrs for irreligion; they are even martyrs for immorality.”
—Gilbert Keith Chesterton (1874–1936)
