The present report describes two individuals from the same family whose symptoms were typical of the clinical characteristics of type 2 benign recurrent intrahepatic cholestasis. [ncbi.nlm.nih.gov]

In the present study, the ROR was calculated as 15.7% during an episode of jaundice which was comparable to that of the normal liver (13.7%) as reported previously ( 6 ). [spandidos-publications.com]

• Long Arm

  Genetic studies have mapped the defect of this disorder to the long arm of chromosome 18 and a gene that codes for a P-type ATPase, which appears to be involved in aminophospholipid transport. [ncbi.nlm.nih.gov]

  Each chromosome has a short arm designated “p” and a long arm designated “q”. Chromosomes are further sub-divided into many bands that are numbered. For example, “chromosome 7q21.1” refers to band 21.1 on the long arm of chromosome 7. [lifewithnogallbladder.com]

• Pruritus

  Since all former approaches to medical treatment of the patients severe pruritus were ineffective, the patient was treated by 3 sessions of albumin dialysis (MARS, Molecular Adsorbents Recirculating System). [ncbi.nlm.nih.gov]

• Suggestibility

  It has been suggested that an imbalance between the gut absorption of bile acids and the liver excretion possibly causes the development of cholestasis. [ncbi.nlm.nih.gov]

• Seizure

  Conclusion: Tremors, Dystonia, Dysarthria are frequent neurological manifestations but Seizures are an infrequent component of Wilson’s disease. [japi.org]

In conclusion, although a rare condition, the possibility of BRIC should be considered and an appropriate workup should be performed when patients present with severe pruritus, an increase in direct bilirubin and a mild increase in transaminase levels [spandidos-publications.com]

• Bile Acids Increased

  During the icteric phase, serum levels of total bile acids increased, most being conjugates of primary bile acids. Electron microscopy revealed that the bile canaliculi were filled with an increased volume of granular substances. [ncbi.nlm.nih.gov]

  Concomitant with loss of canalicular bile secretion, cholestatic bile acid uptake increases and the bile acid pool increases across the intestinal wall because of reduced in farnesoid X receptor expression[19-22]. [ghrnet.org]

Treatment is often ineffective and symptoms, particularly pruritus, can be severe. [ncbi.nlm.nih.gov]

Prognosis The prognosis is generally good with a tendency for a reduction in the frequency of attacks with age. However, progression from BRIC to PFIC and cirrhosis has been reported in the literature, indicative of a clinical continuum. [orpha.net]

The serum transaminases remain normal even during symptomatic exacerbations indicating a good prognosis. [ijdvl.com]

Prognosis: This disease is fatal without a liver transplant. Ancillary treatments and support: Antipruritic medications can have a role in severe cases. [wohproject.org]

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]

Prognosis is better for cholestatic compared to hepatocellular DILI, based on the data from Spain and Sweden but the opposite was found in results from the United States. [wjgnet.com]

Authors report 6 cases of benign recurrent intrahepatic cholestasis (BRIC), a rare disease of unknown etiology first described 30 years ago by Summerskill and Walshe, and thought to represent a study model for human cholestasis. [ncbi.nlm.nih.gov]

Though the etiology is obscure, the coincidence in two boys, possibly related (2), and in two brothers (3) suggests that this may be a constitutional form of jaundice. [annals.org]

Summary Epidemiology The prevalence of BRIC is unknown. Clinical description The first cholestatic episode can occur at any age but onset within the first two decades of life is most common. [orpha.net]

Epidemiology [ edit ] Consanguinity is believed to be a major risk factor. Similar transport protein mutations are believed to pose a higher risk for intrahepatic cholestasis of pregnancy. [en.wikipedia.org]
