Hepatomegaly is enlargement of the liver. [4] It is a non-specific medical sign , having many causes, which can broadly be broken down into infection , hepatic tumours , and metabolic disorder . Often, hepatomegaly presents as an abdominal mass .
Signs and symptoms of liver masses vary from being asymptomatic to patients presenting with an abdominal mass, hepatomegaly, abdominal pain, jaundice, or some other liver dysfunction. Treatment varies and is highly specific to the type of liver tumor. [3]
Treatment of NAFLD is generally by dietary changes and exercise to bring about weight loss. [1] In those who are severely affected, liver transplantation may be an option. [1] More than 90% of heavy drinkers develop fatty liver while about 25% develop the more severe alcoholic hepatitis. [4]
Natural killer cells are the primary drivers of the initial innate response and create a cytokine environment that results in the recruitment of CD4 T-helper and CD8 cytotoxic T-cells. [63] [64] Type I interferons are the cytokines that drive the antiviral response. [64] In chronic Hepatitis B and C, natural killer cell function is impaired. [63]
Patients commonly present with symptoms and signs of infection of the reticuloendothelial system, including generalized lymphadenopathy, hepatomegaly, and splenomegaly. The respiratory system is commonly involved as well; cough, fever, dyspnea, and chest pain may be present, reflecting the probable inhalational route of acquisition.
Cysteine is an essential amino acid that acts as the limiting amino acid for glutathione synthesis in humans. Factors that increase demand for glutathione may increase demand for cysteine, and hence methionine. Such demands have been hypothesized to increase the risk for kwashiorkor.
The principal treatment for this feature of GSD Ib is filgrastim; however, patients often still require treatment for frequent infections, and a chronically enlarged spleen is a common side effect. [4] GSD Ib patients often present with inflammatory bowel disease. [5] It is the most common of the glycogen storage diseases.
Hepatomegaly: Medical imaging: Longitudinal axis > 15.5 cm at the hepatic midline, or > 16.0 cm at the midclavicular line [14] Autopsy: Weight over upper limit of standard reference range, of 1,860 g (4.10 lb) in men [12] and 1,770 g (3.90 lb) in women. [13] Lymph nodes: Lymphadenopathy: Generally 10 mm [15] [16
