Q

Can AZA be used in AIH?

A

If no cirrhosis, then yes can be used. But can’t be used for induction therapy because it takes 6-8 weeks to take effect.

Q

When to wean meds for AIH?

A

After two years of remission, can wean. Can do biopsy before withdrawing IS, because if inflammatory activity is present, relapse is almost universal, and therefore IS should be continued in the long term.

In adults, biopsy is not absolutely necessary before withdrawal. In children, it is strongly recommended

58
What should you give household contacts of someone with Hep A
post exposure prophylaxis for hepatitis A infection vary by age and health status. For healthy people over 12 months to 40 years old, hepatitis A vaccine is preferred over IG due to likelihood of response, long-term protection, and equivalent efficacy to IG. IG is recommended within TWO WEEKS of exposure for persons over 40 years old due to lack of knowledge on vaccine performance and possibility of more severe presentation in patients with older age.WHAT HEP

How is overt HE defined? How is covert defined?
Grade 2 Asterixsis Disorientation Covert: diagnosed with psychomotor or neuropsychological testing
76
How do you use ammonia in HE?
Increased blood ammonia alone does not add any diagnostic, staging, or prognostic value for HE in patients with CLD. A normal value calls for diagnostic reevaluation however
77
What type of hemorrhage is seen in HE
Intracerebral hemorrhage is five times more likely in patients with HE. So a CT isn't needed to diagnose HE, but should be used to rule out other diseases like a bleed
78
When should rifaximin be used in HE?
Not enough data for rifaximin alone, should be used in conjunction with lactulose for prevention of recurrence of HE Rifaximin added to lactulose is the best-documented agent to maintain remission in patients who have already experienced one or more bouts of OHE while on lactulose treatment after their initial episode of OHE
79
What are alternative regimens for HE?
IV LOLA Oral (not IV) BCAA for additional or alternative treatment ORAL BCAA may have more of an effect on promotion of lean body mass rather than treatment of HE Metronidazole or neomycin for alternative treatment
80
What type of HE do you treat?
Overt only
81
How do you prevent post TIPS HE
Routine prophylaxis is NOT recommended
82
When can prophylactic therapy for HE be discontinued?
Under circumstances where the precipitating factors have been well controlled (i.e., infections and VB) or liver function or nutritional status improved, prophylactic therapy may be discontinued
83
What influences the risk of repeated episodes of HE?
1. overall liver function 2. body habitus/ muscle mass 3. controlling precipitins factors If these are all controlled, prophylactic therapy may be able to be stopped
84
What are the daily energy intakes for HE?
35-40 kcal/kg ideal body weight
85
What are the daily protein intake for HE?
1.2-1.5 g/kg/day
86
What is the most common pediatric liver tumor
hepatoblastoma Can be asymptomatic or painful from a larger tumor
87
What is the best thing for survival in kids with hepatoblastoma
resection (but this has to be possible anatomically) AFP is a great biomarker for tumor
88

elevated bilirubin on Day of life 1
91
What is the triangular cord sign
seen in biliary atresia increased echogenicity along anterior wall of portal vein
92
What is the gold standard dx for BA? What are other helpful tests
Intraoperative cholangiogram or PTC- want to see dye go into the liver and out of intestine U/S - triangular cord sign HIDA - want to see good excretion into intestine Liver biopsy- not diagnostic, will see bie duct proliferation that detects extra hepatic biliary obstruction
93
What is kasai
all extra hepatic biliary tissue excised creation of roux en y roux jejunum anatomiste to portal plate restores bile flow
94
What determines need for transplant in BA after kasai
time to kasai those who got kasai within 30 days DOL were more likely to survive with native liver than those who got kasai >90 day of life Total bili <2 at 3 months post kasai associated with higher survival with native liver
95
What is the definition of ALF in peds
1. absence of pre-existing liver disease 2. biochemical evidence of acute liver disease --coagulopathy not corrected by vit k ----INR >1.5 + HE or INR>2 --> status 1A
96
Vit A deficiency
ocular changes: dry eyes and night blindness Skin changer: poor wound healing, hyperkeratosis growth retardation *if not responding well to supplementation, can give zinc as well
97
what is therapeutic target of vit D
>30ng/mL
98
How is it best to supplement vit D in children?
D3, because it has better water solubility and therefore better absorption
99
Vit E defiiciency
Hemolytic anemia Nuerologic deficits (ataxia, peripheral neuropathy) muscle pain High doses antagonize Vit A and adversely affect wound healing and platelet function
