Enlargement of the Liver

Treatment

  • Patient conditions remained stable with a median follow-up of 40 months (range, 3-53), and treatment tolerance was good.[childrenliverindia.org]
  • Medical treatment consisting of cholestyramine, phenobarbital, UDCA and/or rifampicin was started in all pts immediately after diagnosis of PFIC.[journals.lww.com]
  • New treatments, such as the development of the farnesoid X receptor agonists for the treatment of PBC, are highlighted. Current guidelines and areas of uncertainty are also covered.[books.google.com]
  • Partial External Biliary Diversion (PEBD) PEBD may be used as the first choice of treatment for patients who have not yet developed cirrhosis. This treatment helps reduce circulation of bile acids in the liver.[cincinnatichildrens.org]

  • Most children with PFIC caused by mutations in ABCB11 who undergo PEBD have a favorable long-term prognosis including histological improvement and long-term survival without the need for liver transplantation. List of papers: I.[openarchive.ki.se]
  • Prognosis [ edit ] The disease is typically progressive, leading to fulminant liver failure and death in childhood, in the absence of liver transplantation.[en.wikipedia.org]

Etiology

  • The book emphasizes not only the pathology seen in biopsy and surgical material, but also the most pertinent clinical and laboratory findings including epidemiology, etiologic and pathophysiologic concepts, and the differential diagnoses.[books.google.com]
  • Etiology PFIC2 is due to mutations in the ABCB11 gene (2q24) encoding the bile salt export pump (BSEP) protein resulting in impaired biliary bile acid secretion which leads to decreased bile flow and bile salt accumulation in hepatocytes with ongoing[orpha.net]
  • Regardless of the etiology of the cholestasis, bile accumulates in the liver, which causes damage and results in lower concentrations of intestinal luminal bile.[acgcasereports.gi.org]

  • Decreased bile flow also prevents the body from being able to absorb fats and vitamins as it should. Each person is born with many genes that make up their body. These genes are passed on to them (inherited) from their parents.[cincinnatichildrens.org]
  • Prognosis Early treatment with UDCA or biliary diversion may prevent significant morbidity and mortality from end-stage liver disease.[orpha.net]
  • We demonstrate that in a patient with PFIC 2 and severe refractory vitamin E deficiency, liver transplant can improve vitamin E absorption, prevent further neurological sequelae, and reverse prior neurologic dysfunction.[acgcasereports.gi.org]
  • Ursodeoxycholic acid therapy (UDCA) should be initiated in all patients to prevent liver damage but is not fully efficient. 12, 13 Rifampicin is helpful to control pruritus.[nature.com]
