Acute-on-chronic liver failure, ACLF, cirrhosis, acute hepatitis

50 patients of Acute-on-chronic liver failure (ACLF) will be enrolled and randomized into G-CSF+EPO or Placebo arms Treatment protocol To administer G-CSF (in prefilled syringe) at a dose of 5 µg/kg s/c at days 1, 2, 3, 4, 5 and then every 3rd day till day 28 (total 12 doses), along with Darbopoetin alpha 100 mcg/ week (in prefilled syringe) for 4 weeks (total 4 doses). Standard medical therapy included as per requirement lactulose, bowel wash, albumin, terlipressin, antibiotics (if indicated) will be continued and recorded. Pentoxiphylline in alcoholic hepatitis and Tenofovir in Hep B reactivation Controls: Standard medical therapy will be given along with placebo in similar prefilled syringes. Follow up Physical examination will be done daily, after 1 week and at 4 weeks, at 2 months, at 3 months and at 6 months CBC on alternate day for 1 week, at end of 1 week and then at end of 4 weeks , at 2 months, at 3 months and at 6 months KFT on alternate day for 1 week, at end of 1 week and then at end of 4 weeks, at 2 months, at 3 months and at 6 months LFT along with PT/INR on alternate day for 1 week, at end of 1 week and then at end of 4 weeks, at 2 months, at 3 months and at 6 months AFP at baseline, after 4 weeks, at 3 months and at 6 months Liver regenerative potential efficacy testing at baseline and after 4 weeks

50 patients of ACLF will be enrolled and randomized into G-CSF+EPO or Placebo arms Baseline investigations: * Hematology * CBC, Prothrombin time and INR * Peripheral smear, Retics * Biochemistry * Liver function testing, AFP * Kidney function test * Etiology of acute event: * Infectious etiology: IgM anti HAV, IgM anti HEV, IgM anti HBc ( If HBsAg +ve), IgM anti HDV ( If HBsAg +ve), HEV RNA * Non Infectious etiology: Alcohol binging in last 4 weeks, hepatotoxic drugs, ANA (\>1: 80), IgG , surgeries in past 4 weeks, acute variceal bleed within 4 weeks * Etiology of underlying chronic liver disease : * Infectious etiology: total antiHBc, anti HCV, HCV RNA, HBV DNA * Non infectious etiology: Autoimmune markers, copper studies, iron studies, HOMA IR, FBS Ascitic fluid analysis ( wherever its possible) UGI endoscopy Imaging USG abdomen with Doppler for spleno-portal axis CECT- Triple phase upper abdomen Liver regenerative potential efficacy testing (wherever it is possible) Histology ( by transjugular liver biopsy) Liver Dendritic cells ( CD11c, CD40, CD 54, CD 123, BDCA 2 staining) by flow cytometry CD 34+ cells and CD 133+ cells measurement in hepatic venous blood, peripheral blood and liver biopsy by flow cytometry Markers of proliferation like ki- 67, proliferating cell nuclear antigen (PCNA) in hepatic venous blood and liver biopsy Markers of angiogenesis like VEGF, v WF in hepatic venous blood Measurement of Hepatic venous pressure gradient ( HVPG) Treatment protocol To administer G-CSF (in prefilled syringe) at a dose of 5 µg/kg s/c at days 1, 2, 3, 4, 5 and then every 3rd day till day 28 (total 12 doses), along with Darbopoetin alpha 100 mcg/ week (in prefilled syringe) for 4 weeks (total 4 doses).
