- Detailed Description
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)
