100 ml/kg/day); 0.9% NaCl, Ringer’s solution 5% glucose, albumin 5 ml/kg

enterosorption 2-3 wks lactulose for 10-14 days desoxycholic acid (ursophalk) in case of cholestasis 10

mg/kg prednizone (in possibility of fulminant form

development and for infants before 1 year with unfavorable premorbid background):

2 - 3 mg/kg/day divided in 4 equal doses 7-10 days

Heptral (tabl. - 0.4 g, amp. - 0.4 g) 1-2 tabl. 3 times a day (20-25 mg/kg/day)

Essentiale (caps., amp.) 1-2 cap. 3 times a day Carsil (dragee) 1-2 dragee 3 times a day Hepabene 1-2 dragee 3 times a day Thiotriazolinum 1 tabl. 3 times a day Chophytol 1-2 tabl. 3 times a day

Treatment of fulminant form Straight bed regimen Diet N 5a with protein restriction up to 40% Intravenously:

prednizone 10-15 mg/kg/day divided in 4 equal doses

detoxication therapy (total – 50-100 ml/kg/day) with diuresis control;

extracorporeal detoxication in case of ineffective previous therapy plasmapheresis

hyperbaric oxygenation

Treatment of fulminant form in case of edema, ascytis – water-electrolyte balance

correction K-serving diuretics (verospiron, triampur) Fresh frozen plasma 10 ml/kg as coagulation factors

donator Heparin 100-300 IU/kg in possibility of DIC-

syndrome development Protease-inhibitors (trasilol, contrical, gordox) in

case of DIC-syndrome development Antibacterial therapy for bacterial complication

prevention (less hepatotoxic medicine) Enema and stomach-washing lactulose for 10-14 days

Discharge from the hospital, supervision, control

patients with mild and moderate forms can be treated at home;

discharge on 15-20 day of illness with the remaining phenomena (hepatomegaly, slight increased ALAT, ASAT, dysproteinemia);

Finish treatment in dispensary cabinet: first examination - in 7 days, then - in 1, 3, 6 months. In absence of the remaining phenomena - stop dispensarization;

can visit school on 40-50 day, release from physical education on 3-6 months, sport - 12 months
