PSC and PBC are the most commonly recognized cholestatic liver disease in the adult population
Biliary atresia and Alagille syndrome are commonly recognized in the pediatric population
In infants, the causes are usually congenital or inherited -usually jaundice
In adult patients “silent” progressive cholestatic liver disease for years prior to development of symptoms such as jaundice and pruritus

PSC in Children versus Adults
The incidence in children - 0.23 cases/100,000 person-years1.11 / 100,000 in adults (Canada), male predominance (62%)
Cholangiocarcinoma in children-extremely rare
May associated with immunodeficiencies, neoplasms (eg,Langerhans cell histiocytosis), trauma, cystic fibrosis and sicklecell
SC may have strong features of autoimmunity (autoimmune SC)

Autoimmune Sclerosing Cholangitis in Children
Often associated with florid autoimmune features: elevated titres of ANA and SMA; elevated IgG; and interface hepatitis
This variant of PSC is diagnosed in 1.4–17% PSC patients
The same prevalence as AIH-1 in childhood

AIH /PSC overlapping syndrome in adults
Bile duct injury and ductular reaction are very common (83%) in newly diagnosed AIH and cannot be predicted biochemically
Bile duct injury may subside in the majority of treated AIH cases while DR tends to persist during follow up
Part of the spectrum of AIH with dissimilar responses to treatment and do not necessarily an overlap syndrome)

Overlap syndrome AIH/PSC-outcome
Accepted to constitute a variant of the primary disorder, mostly PSC,
In all patients, the original diagnosis was AIH
All patients insufficiently responded to immunosuppressive therapy and eventually showed typical signs of a large duct PSC
Increasing evidence for a better outcome of PSC/AIH overlap compared to classical PSC
This would indicate that immunosuppression may benefit both conditions

Immunomodulatory effect of vancomycin on Treg in pediatric inflammatory bowel disease and primary sclerosing cholangitis
Vancomycin affect TNF-α pathways, an immunomodulator; separate from its function as an antibiotic
OV administration may result in the induction of regulatory T (Treg) cells (anti-inflammatory properties)
OV was an effective treatment for concomitant PSC and IBD in children

Vancomycin in Adults
35 patients with PSC - 4 groups: vancomycin 125 mg or 250 mg four times/day, or metronidazole 250 mg or 500 mg three times/day for 12 weeks
Vancomycin appears to be the better-tolerated drug
Both low and high-dose vancomycin groups achieved significant decrease in ALKP
The low-dose group normalisation of ALKP
The low-dose group other biochemical improvements, a decrease in Mayo PSC risk score, Bilirubin and CRP

• The family history may reveal ICP in their mothers, a relation between genetic defects in MDR3 and ICP
• Herheterozigous carrier state of ABCB4 gene mutation
