Spontaneous bacterial peritonitis (SBP) is the development of a bacterial infection in the peritoneum, despite the absence of an obvious source for the infection. [1] It is specifically an infection of the ascitic fluid – an increased volume of peritoneal fluid. [2] Ascites is most commonly a complication of cirrhosis of the liver. [1]
Ascites (/ ə ˈ s aɪ t i z /; [5] Greek: ἀσκός, romanized: askos, meaning "bag" or "sac" [6]) is the abnormal build-up of fluid in the abdomen. [1] Technically, it is more than 25 ml of fluid in the peritoneal cavity, although volumes greater than one liter may occur. [4]
Spontaneous bacterial peritonitis (SBP) is a peculiar form of peritonitis occurring in the absence of an obvious source of contamination. It occurs in people with ascites, including children. Intra-peritoneal dialysis predisposes to peritoneal infection (sometimes named "primary peritonitis" in this context).
Infections that are common in those in the hospital with cirrhosis include spontaneous bacterial peritonitis (with a prevalence of 27% among hospitalized patients), urinary tract infections (22-29%), pneumonia (19%), spontaneous bacteremia (8-13%), skin and soft tissue infections (8-12%) and C. difficile colitis (2.4-4%).
Chronic liver failure usually occurs in the context of cirrhosis, itself potentially the result of many possible causes, such as excessive alcohol intake, hepatitis B or C, autoimmune, hereditary and metabolic causes (such as iron or copper overload, steatohepatitis or non-alcoholic fatty liver disease).

The most common infection is peritonitis, followed by lung, skin, and urinary infections, meningoencephalitis and in the most serious cases septicaemia. The most notable of the causative organisms are Streptococcus pneumoniae and Haemophilus influenzae. Spontaneous bacterial peritonitis can develop where there is ascites present. This is a ...
Hepatic veno-occlusive disease (VOD) or veno-occlusive disease with immunodeficiency is a potentially life-threatening condition in which some of the small veins in the liver are obstructed. It is a complication of high-dose chemotherapy given before a bone marrow transplant or excessive exposure to hepatotoxic pyrrolizidine alkaloids .
